Description

Method for installing at least one cable and/or hollow pipe in a laid supply or discharge pipeline, in particular into an underground pipe system or pipe network and the like

The invention relates to an installation method for installing at least one cable and/or hollow pipe in a pipe already laid to be used as a supply pipe or discharge pipe, in particular to an underground pipe system or pipe network and the like object. The cables and/or hollow pipes to be laid therein are introduced into the interior of the duct and fastened to its walls.

The field of communication shows a continuous high growth rate, and this growth has no end in sight so far. While developments have revolved around satellites, particularly in long-range, large-area communications, the transmission of data and information via underground cables has remained at least as important as via satellites. In addition, cables and wires located underground are regaining importance with the use of fiberglass cables. Because this cable can transmit large amounts of data at high speed.

Especially using fiberglass cables, people expect to establish a communication network with a wide coverage quickly, quickly and at low cost. The laying of such cables or conductors naturally requires a large amount of earthworks unless there are already installed hollow ducts or other underground ducts available.

A now practical method of installing cables and/or hollow pipes into which cables - such as information transmission cables - can be drawn, is in existing underground pipes, such as in In drainage pipes, which may have a large cross-section, the newly installed cables or hollow pipes are fastened to the wall by means of cable clips or pipe clips at fixed distances by driving anchors into the underground pipe wall. This method is naturally very labor-intensive and expensive, and can only be carried out in underground pipes with a large cross-section, so that workers can enter. Unless a robot with a camera to guide and monitor is used for the installation work, then cables or hollow pipes can also be installed without the underground pipe being inspectable.

It is also possible to fix several hollow tubes or cables by means of clamping rings which are stretched over the entire circumference of the channel cross-section. Such tensioning snap rings can also be laid by means of robots, and the installation site also includes existing underground pipes with a small cross-section, such as drainage pipes, but this cross-section is still large enough for these robots, i.e. The diameter of these pipes must not be less than 200mm. It can be seen that the hollow pipes and cables installed later, no matter whether they are fixed by pipe clips or cable clips, or by the tension snap ring mentioned above, all will stand the test of harsh pipeline operating conditions. Such pipelines must withstand waste water scour at high water flow rates and high pressure-channel cleaning. Especially at the wire clips and tensioning rings, empirically, solid matter from the waste water deposits, so that sooner or later the channels are blocked. It must therefore be taken into account that these fixing elements of cables or hollow pipes installed later may not be able to withstand the resulting blocking pressure. For this reason, it is unlikely that this approach will be implemented in the future, taking into account the expected disturbances.

In addition, normal channel operation becomes more difficult. Corresponding channels can no longer be closed with blower plugging or pressure tested.

According to DE-U1 298 01 424, for the placement of cables in non-visitable waste water pipes, flat hollow shapes are used, such as a cable channel, which are made of metal or plastic or are fixed and glued to underground pipes on the inner wall, or fixed on it. For this kind of placement process, in the gas pipes, water pipes and waste water pipes that cannot be inspected, people need to use robots to enter the corresponding pipes.

The downside of this robotic system is that the passageway had to be refurbished beforehand. If the channel has not been repaired before, after the robot has hung the cable, it is then necessary to cover the cable with a pipe cover, which is technically impossible in most cases. And this is a crucial, additional cost-intensive process step.

There are also tunnel repair methods in which dimensionally stable pipe sections are inserted into an old or damaged pipe and connected to each other. In this measure, the space between the newly inserted pipe and the old pipe can be filled with a suitable filling substance, a so-called "clogging agent". In the case of this method of filling in a shape-fixed re-alignment pipe, such as proposed by the company Hobas Rohre AG in Switzerland, it is also proposed to insert cables or hollow pipes in the space between the new pipe and the old underground pipe. It can be seen that the method is complex in principle and always needs to be connected with the installation of these dimensionally stable tube covering elements made of metal or plastic if cables or hollow tubes for telecommunication are to be accommodated.

When an inner line has already been installed, that is to say an inner covering is already present, additional cabling or hollow pipe laying is always associated with further inner line refurbishment. It doesn't matter where the passage needs to be refurbished but has not been refurbished, and even brings economic advantages.

However, this means that if such additional cables are installed in intact or even newly laid passages, ie in passages which do not require refurbishment, the associated refurbishment results in additional work and additional costs.

The object of the present invention is to avoid the above-mentioned disadvantages existing in the prior art and to provide a method. It enables the additional laying or subsequent installation of cables and/or hollow pipes in existing channels and is directly competitive with conventional excavation construction methods. In this case, reliable protection of cables and pipes installed later can be provided, technically possible prior or subsequent renovations can be carried out as required, but are not essential tasks and do not restrict the operation of the passage. Furthermore, a subsequent inner cable refurbishment can also be dispensed with, wherein the cables and/or hollow tubes in the channels can remain unchanged.

This is accomplished by means of a method of beginning to mention types. It is characterized in that a tubular or hose-shaped lining is pushed and/or pulled into the laid pipe, wherein at least one flexible empty pipe and/or a cable is arranged in the area of its outer surface .

Preferred embodiments of the invention are given by the dependent claims.

The basic idea of the invention is to push or pull a tubular inner lining into existing, laid underground pipes, underground piping systems or networks and the like, also including ventilation ducts, and Between the inner wall of the existing underground pipe, a new cable or a hollow pipe is placed, so that the cable can be inserted in it later. In this way, individual cables and/or hollow pipes to be newly laid can be fastened and held in the underground pipe without the use of additional suspension elements or fixing elements. In addition, the use of the tubular liner results in a new smooth pipe wall through which the waste water flows without creating disturbance spaces that block its flow through the underground pipe, or in these areas, due to the solid matter carried by the waste water. deposition to form a blockage. Conversely, the smooth interior surface of one such new tubular liner also facilitates fluid flow. All newly laid hollow pipes and cables are isolated from the fluids flowing in the underground pipes without the risk of corrosion or abrasion associated with newly installed cables. At the same time, existing underground pipes can be additionally sealed or refurbished using this method. It can be seen that by this method, practically unlimited possibilities can be obtained to establish or expand data transmission networks with a rather simple structure, since in practice all households or other industrial and community facilities are connected to wastewater underground. Pipes are connected, the latter being able to be utilized even those underground pipes having a relatively small diameter, for example between 80 and 150 mm in diameter. This is because the method of the present invention can also be applied to these underground pipes.

It may be the case that an existing installed underground pipe, underground pipe system, or network is such that, in order to pull a tubular liner in, its outer diameter must be smaller than the inner diameter of the underground pipe in which Push or pull in the tubular liner. Especially in the following cases, as the tubular lining is an irreversibly deformable hose, the outer diameter of which is such that it can be easily pulled into the underground pipe. Next, the hose is deformed by suitable measures, such as being subjected to a high internal pressure, and here pressed against the inner wall of the underground pipe, so that between the deformed hose and the underground pipe wall, cables and /or the hollow tube is squeezed and cannot move.

As such a deformable hose, a flexible hose is preferably used. Furthermore, its cross-section should be able to fold over so as to form a flat strip. It is simply pulled into existing underground pipes or into an underground pipe system or network. By pulling in the hose, the necessary cables and hollow tubes can be placed on its outer surface at the same time. After the hose has been pulled into the underground pipe, the end of the hose can be closed and pressed against the inner wall of the underground pipe by filling it with a liquid medium or a gaseous medium, such as compressed air. If the material from which the hose is produced is a heat-curable or UV-radiation-curable material, the hose is hardened irreversibly against the inner wall by heating or UV radiation. Once the hose has hardened in place, the pressure acting on the inner space of the hose can be removed. The hose then fits snugly against the inside wall of the underground pipe, holding the cable and hollow pipe in place.

In principle, it is possible to place installed cables and/or hollow pipes (for the introduction of cables) on any side of the tubular lining and thus on any side of an existing underground pipe. However, these hollow pipes and/or cables are preferably arranged in the upper region of the outer surface of the tubular covering so that they are located above the underground pipe after the installation of the tubular lining.

In order to facilitate installation work on site, ie on a building site, it can be advantageous to use a tubular lining which is already assembled in its wall and thus contains hollow tubes and/or cables. These cables and hollow tubes can be integrated in the wall thanks to the deformable hose as an inner lining.

In order to keep the hollow pipes and/or cables to be installed in a fixed configuration with it during the installation of the tubular liner, it is only necessary to place them on the outer side of the drawn or pushed in tubular liner along the It is sufficient to fasten it in points on the outer side along its length. Such point fixing can also be done directly on site during the installation of the tubular lining with simple tools. Thus, individual installed pipes or cables, if desired, can be secured directly over the tubular liner as it is drawn in.

If a hose is to be drawn into an underground pipe, it should be a textile hose, preferably a fiberglass hose, from a strength point of view. In addition, hoses impregnated with hardenable resin, woven hoses and/or braided hoses are also available as hoses. Resins can be selected here that harden when exposed to UV-radiation or heat, so that the hose, which is pressed against the wall of the channel under pressure, can harden in place. Since the resin is viscous until it hardens, a hose-like film should be placed on the outside and/or inside of the hose so that the walls of the hose do not stick to each other, especially when the hose is folded When the state is pulled into the underground pipe.

If the tubular lining is used as a dimensionally stable material, i.e. is not pressed into its final shape after being drawn in and subsequently hardened, the tubular lining, when inserted into the underground pipe, will Helical, shape-stable forms coiled from strip material (Bahnenmaterial) will have particular advantages. For this purpose, a corresponding mechanical structure is placed in an access shaft and the strip is fed into the machine as a continuous strip. In the machine, the strip is then wound into a helix, the longitudinal sides of which adjoin one another in the longitudinal direction are connected to one another by suitable methods, for example by crimping or welding. The helical pipe is then continuously pushed into the underground pipe, while the cable to be installed and/or the hollow pipe to be installed is fed in on its outer wall. To form the helically configured tube, the tape primer used can be a metal tape or a plastic tape.

Another possibility is, under certain conditions, preferably to use a plastic pipe as the tubular inner lining, whose wall cross-section is drawn into the existing underground pipe in a folded configuration and subsequently with the aid of a A heated medium re-deforms to its original tube cross-sectional shape under the action of internal pressure.

In order to make the shape-stable pipe forming the tubular lining rest tightly on the inner wall of the underground pipe, the following method is advantageous, in which a plastic pipe is used as the tubular lining, the pipe cross-section of which is drawn into the existing Before there is an underground pipe, it is mechanically reduced by drawing and extrusion, and after being pulled in, the original pipe cross-sectional size is restored by canceling the tensile stress. By means of such a measure, it is possible to make the tubular inner lining tightly abut against the underground pipe wall, and thus the hollow pipes and/or cables drawn in between the outer wall of the plastic pipe and the inner wall of the existing underground pipe are Hold tightly against the tube wall.

Subsequent installation of cables and/or hollow pipes in existing underground pipes, underground pipe systems, pipe networks, or the like is preferably started at so-called access shafts or other easily accessible locations. In these installation entry areas, the ends of the cables and/or hollow pipes placed between the tubular lining and the existing underground pipes can be passed into a distribution box and/or connection box so that they can be These connection boxes are connected to each other to form a network, or to an existing communication network, or to a power grid; the same is true for the hollow pipes, which can be accessed through the connection boxes, cables, such as data transmission The cable can then be drawn into the hollow tube.

The assembly material used for wetting the cables and/or hollow tubes and for bonding the cables and/or hollow tubes to each other and to the walls of the tubes simultaneously constitutes protection on all sides. This is especially the case when the cables and/or hollow tubes are completely embedded in the assembly material, ie similarly cast.

In a further preferred embodiment, the cables and/or hollow pipes to be laid are wetted with an adhesive mounting compound. They are then brought into the pipe with an assembly hose as a hose-like lining. The fitting hose is then spread out, and the cable and/or hollow tube is thus pressed against the tube wall, and after a sufficient holding time so that the cable and/or hollow tube sticks to the wall, will act on the fitting The pressure on the hose is removed. The special advantage of this method is that only one assembly hose is used, which can be removed after the cable or hollow pipe has been placed in the already laid pipe and can be reused, thus remaining in the existing installation. In a pipe, such as an underground pipe, only cables or hollow pipes are placed. Thus, with this method, cables and/or hollow pipes can be installed side by side, at defined intervals, and in various other ways at the same time.

The assembly hose used, as already mentioned above, is preferably removed from the tube after assembly; in the case of such an assembly hose made of a suitable material, the assembly hose can be used several times Use to install cables or hollow pipes into existing supply or discharge piping/systems.

The installation positions for the subsequent installation of the cables or the hollow tubes on the inner wall of the channel can be predetermined by positioning the cables accordingly on the mounting hose. In most cases, however, this assembly location is located in the upper semicircle or upper arc of the cross-section of the duct in which the cables and hollow tubes are placed.

The cable or hollow tube to be installed is preferably embedded over its entire length in an adhesive mounting material, ie a correspondingly suitable adhesive. Together with this adhesive, they are then pressed against the wet channel inner wall and can be glued there. Such an epoxy resin may be a two-component epoxy resin which can be cured over time, either with additionally supplied heat, or by radiation of a suitable wavelength.

In addition, mineral and/or synthetic inserts, for example in the form of textiles, knits, or even felt, can be used as carrier materials for the mounting material or adhesive. Use suitable materials as needed.

Obviously, after bonding and hardening, the additional cables are firmly connected to the underground pipe wall and are preferably connected in the assembly material, if necessary in the additional carrier material, so that the cables and/or hollow The tube is integrated with the assembly material. If the pipe is a waste pipe, the cable is covered and protected by a defined layer of material with respect to the interior of the pipe and the waste water. The material covering the cables has a smooth transition to the underground pipes and connects them to the tunnel inner wall in a form-fitting and force-transmitting manner. If necessary, an outer covering layer can also be provided, which is used in the form of a strip, that is, such a strip is first placed on the assembly hose, the cables and hollow pipes to be placed are placed on this strip and embedded in the material. The covering layer can also be firmly connected to the carrier material from one side on the outside and remain after the hollow tube has been bonded in the channel.

It is even possible with the given method to increase the static load-bearing capacity of the channels in which cables or hollow tubes are placed, if the adhesive and load-carrying materials used have static material property values.

As assembly hoses to be drawn into the pipeline, flat hoses should preferably be used. The flat hose here means that before it is sent into the channel, it can be stacked into a flat belt at first, so that cables or hollow tubes can be placed on it, and after such a hose is pulled into the channel, Expansion is carried out by means of a suitable fluid, gaseous or liquid, so that the cables and hollow tubes preferably placed thereon are embedded in the viscous material and pressed against the inner wall of the channel. To expand the hose, a gaseous or also liquid medium can be used. Among them, gaseous media such as air are preferred in most cases. To blow up the hose, it can be closed off at one end unless the hose is blown up from both ends.

In order to ensure optimum pressing of the assembly material together with the cables or hollow pipes, the flat hoses should have a slightly smaller circumference compared to underground pipes and should be expandable so that they can be adapted to the conditions in the pipe. The preferred list also includes hoses made of rubber or silicone, which inherently have good separability with respect to the assembly material.

In order to ensure optimal detachment of the fitting hose from the material in the channel after the material has hardened, a separating layer can also be placed between the fitting hose and the adhesive fitting material or adhesive and/or carrier material, Such as a separating layer in the form of a pasty separating substance or a suitable tape, such as a plastic film.

If the cables and/or hollow pipes to be installed in the channel are to be placed on the sides of the channel cross-section ("arches"), it is useful to fasten the separating layer to the assembly hose. A preferred possibility for this is realized by a hook-and-loop connection strip. The material and the cables and/or the hollow tubes are then placed on the separating layer so that they can be positioned exactly relative to the channel cross-section.

Another possibility is to connect the separating layer, for example in the form of a film, to one of the outer carrier material or the insert layer by bonding, which when removing the assembly hose after the cables and/or hollow tubes have been bonded, Remains firmly and adhesively in the channel.

There is the possibility of fastening the separating layer in the form of a strip to the mounting hose by means of a double-sided adhesive tape. Such an adhesive tape can be removed from the pipe at the same time as the fitting hose is being removed or thereafter.

Further details and features of the invention are given in the ensuing description of the exemplary embodiments with the aid of figures. The legend shows:

In order to install cables and/or hollow pipes 2 in existing underground pipelines 1 that have been laid, such as underground sewage pipelines, as shown in FIG. The pipe 3 is drawn from a supply reel 4 and is lowered by an introduction roller 5 into a shaft 6 which is located vertically between the street surface 7 and the underground pipe 1 or channel 8 . The hose 3 can be a textile hose and/or a braided hose, which is impregnated with resin, so that the hose 3 or the flattened strip obtained therefrom is light, flexible and easy to use. During the feeding of the hose 3, for example, a stock roll 11 placed on the supply truck 9, uncoiled cables or flexible hollow tubes are passed around a deflection wheel 10, together with the flattened hose. Send it off. In the region of the insertion roller 5 , the cables and/or hollow tubes 2 can be fixed relatively in a point manner above the flattened hose 3 , so that the cables/hollow tubes 2 cannot move relative to each other. The hose 3 together with the cable/hollow pipe 2 can be drawn into the channel 1 in the shaft 6 by means of a pulling rope pulled in the direction indicated by the arrow 12 . The shaft 6 provides easy access to the channel 1 . The hose 3 is then drawn into the channel and as far as another access (not shown in FIG. 2 ), such as another shaft, so that the end can be accessed there. The hose 3 with the cable/hollow pipe 2 lying thereon lies on the bottom of the underground pipe 1, as indicated by the dotted line 13 in FIG. 2 or the schematic cross-section of the underground pipe in FIG. 1A. The hose 3 is then cut from the supply reel 4 and closed at its two open ends to make it airtight. Compressed air is blown through at least one of the two closed ends by means of a compressor mounted on the truck 9 , blowing the hose 3 up and thus pressing it against the inner wall of the underground pipe 1 . In this way, the cable/hollow pipe 2 is pressed against the upper part of the underground pipe 1, as shown in Fig. 1B. At the position where the flexible pipe 3 abuts against the inner wall of the underground pipeline 1, it is cured in different ways according to the difference of the kind of the flexible flexible pipe 3 used. For example, if the hose 3 is impregnated with a heat-curable resin, heating is applied inside the hose 3 to harden the resin. In the case of using resins that are hardenable by UV-radiation, the interior of the hose 3 is irradiated with infrared light by means of a suitable radiation device. After the hose 3 hardens, the internal pressure can be removed. The cables and/or hollow pipes 2 are then sent to and fixed in a transfer station 14, which is fixed to the wall of the shaft 6 and is easily accessible. The end of the hose 3 can then be fastened appropriately in the transition region of the underground pipe 1 to the shaft 6 , so that the intermediate space between the wall of the underground pipe 1 and the outside of the hose 3 is sealed off. As shown in FIG. 1B , the channel 1 is thus provided with a smooth inner lining, which is protected and sealed at the same time as the cables or hollow pipes 2 abutting against the inner wall of the underground conduit 1 . Starting from the transfer station 14 , the necessary cables, such as data transmission cables in the form of fiber optic cables, can then be pulled into the hollow pipe 2 arranged between the underground tunnel 1 and the hose 3 .

As shown in Figures 1 and 2, this method of later placing cables and/or hollow pipes in an existing underground pipeline, underground pipeline system or underground pipeline network is a very flexible and versatile method. In this way, the existing underground pipeline system can be used to expand the communication network.

What has been described above is a method for installing cables and/or hollow pipes 2 using a flexible, flattened hose 3 in an existing underground pipe system. Shown in FIG. 3A is a cross-section of an underground pipeline 1 . It shows the tube profile formed by folding a deformable plastic tube. Seen in cross-section, the plastic tube is folded inwards from its edges, ie both edges are folded down and face each other. A tube thus deformed, if made of plastic material, exhibits a certain shape stability in the folded state, as shown in FIG. 3A. On top of the hose 3 in this folded state, the cables/hollow pipes 2 are placed and fixed so that they face the upper wall of the underground pipe. When the hose 3 is properly positioned in the underground pipeline 1, the hose is deformed by the heated medium and under the action of internal pressure, and returns to the original pipe cross-section, so it paves the ground for the underground pipeline 1. an inner surface, and at the same time press the cable/hollow pipe 2 against the inner wall of the underground pipeline 1, as shown in Figure 3B.

The above is a method using a hose as a tubular lining. However, FIG. 4A schematically shows an underground pipeline 1 extending between two shafts. The method differs from the method described above in that in FIG. 4A individual pipe sections 16 are lowered from a shaft 3 and pushed into the underground pipeline 1 in sections by means of a pusher 17 . Here, the individual pipe sections 16 are plugged into each other, welded to each other, or screwed to each other by means of a screw thread, thereby being connected to each other. At the same time, the cables/hollow pipes 2 are placed on top of these pipe sections 16 and pushed forward together with the pipe sections 16 . These cables/hollow pipes 2 can be delivered directly from a storage vehicle as shown in FIG. 2 . After the pipe section 16 has been passed forward into the second shaft 3, the cable/hollow pipe 2 is fed into a transfer station 14 and fixed there. The required length of the cables/hollow pipes 2 can already be retained when the first pipe section 16 is fed into the underground pipeline 1 , or these cables or hollow pipes can be extended to the transfer station 14 . If desired, a packing material 15 can then be extruded in the intervening space, or annular space, which may remain, as shown in FIG. 4B .

A network construction using the above method is schematically shown in FIG. 5 . For example, to set up a new information transmission network, it is best to select a laid main underground pipeline 1 of an underground pipeline network, such as a waste water discharge pipeline, to be utilized so that between every two adjacent transfer stations 14 As described above, individual cables/hollow pipes 2 are installed using a tubular lining, for example a hose 3 or pipe sections 16 . Via the existing house connection, i.e. the house connection-underground pipe, it discharges the waste water of a house 18 into the underground pipe 1, also marked here with 1, by pulling in a tubular lining, in this case the most Preferably hose 3, bring the wires/hollow pipes in and snap them between this hose and underground pipe 1. In the premises 18, a relay station 14 is located to connect the household to the newly established network. A special connection point 19 can be provided in the transition area between the house connection underground pipe 1 and the main underground pipe 1 in order to carry out the necessary branching of the cables/hollow pipes 2 there for leading into the house 18 .

The second embodiment shown in FIG. 6 is also for the subsequent installation and laying of cables and/or hollow pipes 102 in an existing underground pipeline 101 , such as an underground pipeline. For this purpose, also in the area of the shaft 103 located vertically between the street surface 107 and the underground pipe 101 , a supply 104 of assembly hoses 105 is prepared lying flat together. In addition, at the supply shaft 103 a stock roll 106 is prepared, on which the cable/hollow pipe 102 to be laid is wound. The stock roll 106 can be carried by a truck 108, for example. From the truck 108 , the cables or hollow tubes 102 are fed vertically downwards into the shaft 103 via a steering wheel 109 provided at the rear of the truck 108 . Below the deflection wheels 109, a container 111 is arranged on a platform 100, in which an adhesive assembly material 112 is contained. In the approximate center of the container 111 there is also a coating device 113 which has two guide and coating rollers 114 . The cables/hollow tubes 102 coming off the deflection wheels 109 are threaded between them. As the cables/hollow tubes 102 fall, they are wetted on all sides, ie on both sides, by the mounting material 112 at the coating device 113 , guide and coating rollers 114 .

The assembly material 112 here is preferably selected from two components-epoxy resin.

Such wetted cables/hollow tubes 102 hang down from the underside of the platform 100, merge with the mounting hose 105, and are placed on top of it. For this purpose, the assembly hose 105 is unwound from the supply reel 104, passes a first deflection wheel 115 and a second deflection wheel 116 erected at the edge of the shaft 103, wherein in particular the second deflection wheel 116 ensures that The mounting hose 105 is a flat strip in the region where it moves with the cable/hollow tube 2 .

The fitting hose 105 may be a silicone hose or a rubber hose.

The assembly hose 105 with the cables and/or hollow tubes 102 lying thereon moistened with the assembly material 112 is then fed into the underground conduit 101 at the bottom of the shaft 103 . During this laying process, the assembly hose 105 is pulled in in the direction of the arrow 117 . For this purpose, a traction rope can be fastened at the end of the not shown assembly hose 105, which belongs to a not further shown traction device, which draws the assembly hose 105 to the other end to communicate with the underground pipeline 101. Shaft 103.

As can be seen in FIG. 6 , two bundles 118 of carrier strips 119 , for example in the form of braided straps, are additionally placed in the container 111 of the assembly material 112 . They are impregnated with assembly material 112 , then guided by application and guide rollers 114 and placed on the cable/hollow pipe 102 to be laid from both sides.

After the assembly hose 105 is fed into the underground pipeline 101 with the cable/hollow pipe 102 above it and possibly additional carrier strips 119, the assembly hose 105 is not shown on another The end at the shaft 103 , not shown, is closed and separated from the supply coil 104 at the shaft 103 shown in FIG. 6 . Next, a pump on the truck 108 is connected to the inner cavity of the assembly hose 105, and fluid, preferably air, is blown into the inner cavity of the hose.

Figure 7A shows the state of the assembly hose 105 pulled into the underground pipeline 101 with the cable/hollow pipe 102 placed on it and two carrying straps 119, one of which is located on the assembly hose 105 and the cable/hollow tube 102, while the other is on the upper surface of the cable/hollow tube 102. From this position shown in FIG. 7A, the fitting hose 105 is blown up by pumping air into the inner space of the fitting hose 105, as shown in FIG. 7B. As the assembly hose 105 is blown up, under the action of pressure, the cable/hollow pipe 102 is embedded in the assembly material 112, and is located between the bearing strips 119, and is pressed against the bottom of the underground pipe 101. on the upper surface.

The fitting hose 105 then remains in the blown up state, as shown in FIG. It is bonded to the wall of the underground pipeline 101. In order to harden the mounting material 112, heating or other radiation treatments may be used depending on the type of mounting material.

After a sufficiently long holding time has elapsed so that the fitting material 112 hardens, the pressure inside the fitting hose 105 can be removed. Under the effect of the elastic contraction, the fitting hose 105 is detached from the fitting material 112 , so that it can be pulled out of the underground pipeline 101 through the shaft 103 again. The cable/hollow tube 102 then remains, as shown schematically in Figure 7C. It can be seen that on the one hand the cable/hollow tube 102 is embedded in the carrier material 102 and on the other hand it is also covered by an outer carrier strip 119 facing the inner space of the channel 101 .

The fitting position of the cable/hollow tube 102 on the inner wall of the channel can be predetermined, but in most cases is located in the upper semicircular region of the channel cross-section.

The mounting material is preferably a two-component epoxy resin, which can also be cold cured.

The hardening process can be accelerated by additional heating, i.e. the hardening time can be shortened. This can be achieved by heating water, air or steam which expands the fitting hose 105 .
