Abstract

To create a drainage device next to the track 1 of a railway line, a trench 4 is first excavated from the ground 12. Then 4 drainage or drainage pipes 24 and filling material 27 and possibly a filter fabric 21 are entered into the excavated trench. The corresponding devices are arranged on one or more work car 2, which is continuously moved forward during the work.

Description

The The invention relates to a method for creating a drainage device next to the track of a railway line according to the preamble of the claim 1.

Next The tracks of railway lines are often drainage facilities. These are parallel to the track with trenches water-bearing backfilling as well as with drainage or drainage pipes.

So far become such drainage facilities manufactured by using conventional construction machinery, in particular excavators, as well as means of transport, in particular railway carriages or trucks. The excavator lifts it out first the ground a trench parallel to the track. Then be in the dug ditch drainage or laid drainage pipes. Finally, backfilling material entered. A filter fleece can also be introduced.

Of the Disadvantage of this known method for creating a drainage device consists in that it discontinuous, viz cyclically performed becomes. The individual workloads are corresponding high. The individual steps are due to the cyclic design not very effective and allow it not, the sequence of work steps in a continuous Consequence implement.

Furthermore is by this design at greater depths a so-called shoring is required, which the side walls of Excavated trench supports. This shoring must by means of an excavator or other lifting device installed in the pit become. According to the progress of the work then the shoring then again clockwise get extended. Again, due to the intermittent work process size Vorhaltelängen of the Verbaus required. Because it always has the length of one Working cycle reserved, installed and rebuilt, before the next Working cycle can start with the provided shuttering quantity. Another disadvantage of the cyclical Verbaus is that he only after the preparation of the excavation can be introduced. This is but the danger of the collapse of the lateral soil of the trench until wrapping given to the Verbaus. This means, however, that worked continuously in the trenches must become, around the collapsing Remove soil.

Often must also a filter fleece to be installed to the filter stability of the built-in Trench material opposite to ensure the upcoming soil. This requires a further, manual step in the intermittent Reconstruction process.

Finally is the survey for the production of the trench hitherto purely manual work. The accuracy and compliance with tolerances is a matter of an experienced Excavator driver and can not be carried out automatically.

Of the The invention is therefore based on the object, a faster and more effective method of creating a drainage device besides the Track to create a railway line.

The technical solution is characterized by the features in the characterizing part of claim 1.

Thereby is a method with a corresponding machine for fast and effectively producing a drainage device next to the track created a railway line. The machine is railbound as well as independently in their handling and operation. The machine is unique and just creating the drainage facility next to the Railway of a railway line. This machine to carry out the The process can all the necessary steps for the production of drainage ditches continuously and perform in sequence. These are first digging the trench, laying the drainage or drainage pipes, the possible installation of a filter fleece and the installation of all fill layers Such as gravel, drainage gravel, covering material or the like. The machine leads all Consumables, which are carried out in one or more shift performances, with them and transported automatically or semi-automatically to the installation site. Due to the design of the corresponding railway wagons with their superstructures together or in different dependencies be controlled. You can Depending on the construction, also installed as a common work car become.

The basic idea of the development according to claim 2 lies in the use of a corresponding trench lifting device in a track-bound or track-guided, continuous method for excavating a trench of a railway line parallel to a track. The excavator performs the excavation of the U-shaped trench so accurately and continuously that no separate backfilling is required. When using a milling device preferably corresponds to the width of the trench exactly the channel to be excavated. This excavation of the trench is carried out continuously during the course of the machine activity. The advantage is a continuous operation with associated high power rates in a single operation. The excavation takes place by means of a corresponding excavation installation both in earth strata and optionally in rock strata, according to requirements and local conditions. Thus, a continuous execution of all steps in a single pass and even at long distances to the track outside the track area is guaranteed. The technical realization thus provides that it is a continuous excavation of the trench. This means that the work car travels continuously on the track and that a corresponding excavating device is arranged on this work car, which synchronously digs out the trench during the forward movement of the work car and the excavated material immediately on the work car or a preceding or downstream other work car or a work car a parallel track feeds. Thus, a rail-mounted excavator in the form of a stand-alone, heavy machine on the work car created that ensures a continuous excavation in particular by means of a router in great depths of several meters and with long distances to the track axis of several meters. The excavated material is disposed of directly after the excavation in a continuous operation. The excavated material can be loaded by means of a conveyor belt to conventional upstream or downstream or located on a neighboring track railway cars or other means of transport, such as trucks, by means of the conveyor belt.

A preferred training proposes according to claim 3 that the Excavated material is milled by the excavating device. It is thus a track-guided or track-bound trencher. The milling has the advantage that it a continuous workflow in the Sense of continuous forward motion of the work car is.

The technical realization of the trencher looks according to the development in claim 4, that as milling device an endlessly circulating band or an endlessly circulating chain or Like. Is used, which is equipped with cutting elements. The advantage of such a milling device is that a continuous excavation up to great depths of several meters as well as with big ones lateral distances to the track of several meters is possible. Here is the milling device preferably interchangeable. By different width milling equipment can Thus, different widths ditches are easily excavated.

there corresponds according to the development in claim 5, the width of the milling device preferably the width of the trench to be excavated. This means, that in a single operation with a single forward drive the milling device the trench dug according to the required dimensions can be.

A preferred training proposes according to claim 6 that the Excavation device on a transverse to the direction of movement of the work car telescopic boom is arranged. This cantilever boom, at the end of which the excavating device, in particular the milling device has the advantage that long distances between the track and the trench to be excavated, and Although distances of several meters. The milling device can be pivoted be around it obstacles, for example in the form of masts to be able to. The stable leadership the excavating device is due to the compact design of the work car with the appropriate structure for reached the excavation. The weight of the unit described above serves to the tilting moment of the overhanging excavating device counteract. The weight can also be optionally variable chosen By, for example, the work car with additional weights equipped becomes. Thus, a continuous execution of all steps in a passage even at large time distance to the track guaranteed.

The Training according to claim 7 has the advantage that on technically simple way very large depths of several meters can be dug. Furthermore is a possibility created for avoiding obstacles. Thus, the Telescopic arms the milling device in their required position in terms of height and direction as well as in terms of Keep the inclination by a corresponding pivoting movement.

The Interchangeability of the excavating device on the work cart according to the development in claim 8 has the advantage that according to the variable Construction site requirement profiles corresponding excavation facilities can be used. The interchangeability but also has the advantage that others Tools as excavation equipment attached as an optional additional solution can be for example, drills or compactors or other tools of any kind.

The development according to claim 9 has the advantage that the positioning of the excavating device, in particular the milling device is automatically automatically adjusted in terms of height and lateral position and in terms of inclination, without the trench dimensions must be measured by hand. Thus, the automatic inclination regulation of the milling device can take place, for example, via laser control as a function of the depth and width of the trench to be excavated. Thus, the entire device can control the work processes semi-automatic or fully automatic, in particular by means of a laser control.

The Respectively the excavated material to the work car can claim according to the development 10 by means of a conveyor belt respectively. Thus, the track-bound or track-guided excavating device in particular in the form of a trencher with a conveyor belt technology combined in that a direct discharge of the excavated material on a connected conveyor belt in the continuous Operation takes place.

Preferably is in accordance with the training in claim 11, the conveyor belt pivotable about a vertical axis. That way that can Excavation material both on railway wagons in front of head or on loading a neighboring track vehicle or a road truck become.

The Training according to claim 12 sees a bunker car for the backfill material in front. The trams give it the funding from the bunker car on conveyor belts. It can If required, several bunker cars are coupled in series to provide enough backfill material to be able to transport. The development thus provides that the work car a storage container for the backfill material which is introduced into the trench. By means of a corresponding transport device or by means of appropriate Transport facilities become the filling materials, such as Gravel fed to the ditch. It can also several layers of different materials are installed. The materials of the different layers are led by conveyor belts. at Demand can be several Conveyor belts in parallel operate.

controlled and guided is the corresponding installation unit via the automatic or semi-automatic upper carriage of the work car.

A preferred training proposes Claim 13 to the effect that after the excavation of the trench through the lateral soil of the trench lateral support boards supported becomes. These support boards are preferably made of sheet metal or steel. This is special at greater depths an advantage, where the danger is very great, that soil is breaking down. The basic idea is thus that during the Propulsion of the work car an automatic entrainment of a Shoring done. This means that the shoring just for the straight length to be processed must be held and that this shoring continuously the pace of the continuous process carried becomes. For this purpose, the support device preferably arranged on a telescopically projecting arm, which the support boards can position exactly in the excavated channel. An essential Aspect is that this lateral support boards synchronous with the forward drive the work car carried become. This means that immediately after digging the trench, the support boards come into effect and protect the trench from collapsing laterally. These supporting boards thus define a so-called ongoing shoring. The lateral ones supporting boards can doing so by a U-shaped profile be defined. The floor (or ceiling) thus forms the rigid one structural connection between the two lateral support boards. This floor or the ceiling does not need it over the whole length this support device to extend. It is sufficient that the soil only over one Part length formed is. Where there is no ground, then, for example the gravel for the cover of the bottom of the trench are introduced. Are then the two side support boards still connected by a horizontal, web-like scraper, The applied gravel can be smoothed and possibly compressed.

The Training according to claim 14 hits the previously mentioned Variant ago, that the The gravel abandoned by the gravel was smoothed by a scraper and possibly compressed. This means that first the bottom of the gravel or Like. Is abandoned, the entrained scraper pulls off the gravel and, if necessary, pre-compressed. This therefore represents a possibility to be without big Effort to feed the excavated soil the soil material. It is only necessary that of a corresponding reservoir of the work car, the gravel stored there, for example by means of a conveyor belt is fed to the trench.

As previously also executed, is the scraper according to the development in claim 15 preferably on the support boards of the ongoing Verbaus for support formed of the lateral soil. This represents a technical simple measure on the one hand for supporting of the lateral soil and on the other hand for stripping the abandoned Gravel

A further development proposes according to claim 16, the storage of drainage or drainage pipes on the work car. The stocked drainage or drainage pipes can be supplied to the trench by means of a corresponding feeder. As a feeder, for example, serve a conveyor belt, which extends laterally next to the work car obliquely in the direction trench. As a result, the drainage or drainage pipes are fed to a certain extent obliquely from behind the trench. The corresponding installation device of the drainage tion or drainage pipes can also serve as a running shoring for lateral support of the soil. But it is also conceivable in principle that the mounting device with the side boards described above are immediately after the excavation combined with each other, so that there is already the installation of drainage or drainage pipes, after previously been abandoned in the area of these side boards of the split floor. As a result, an upper carriage may be less necessary in the optimal case. However, the functions and principles of the two units described above remain the same. They are only united in a facility in the ditch area. In principle, a special transport vehicle can be provided for the drainage or drainage pipes. Here, the drainage or drainage pipes, which have been palletised or specially post-palletized from the factory, can be transported by means of a gantry crane to a laying trolley. This Ablegewagen is thus equipped with the above-described feeder. The gantry crane moves here on its rail wheels on flank rails of train carriages coupled in series. The gantry crane is equipped with a pallet fork or other lifting device, which are capable of transporting the palletized, drainage or drainage pipes. The depositing trolley picks up a fractionated unit of drainage or drainage pipes from the pallets and places them on a cross conveyor. The cross conveyor transports the drainage or drainage pipes to a transfer conveyor. Since the drainage or drainage pipes are stored on standard pallets, a quick evacuation must be possible after emptying this pallet. For this purpose, an additional cross conveyor the pallet can be driven immediately after emptying from the storage area for the new, filled pallet. This ensures that a continuous work progress is guaranteed. In order to ensure a continuous supply of drainage or drainage pipes, several transport trolleys for the drainage or drainage pipes can be additionally strung without trolleys. A gantry crane moves from one wagon to another to transport the pallets. He can transport both the old pallets and the new pallets to the intended workstation.

The Training according to claim 17 beats the automatic feeder a filter fleece before. The filter fleece is on the work cart stored in the form of a nonwoven roll and can be rolled from there and automatically fed to the installation site.

The Training according to claim 18 beats before that on Stop that entered filling material densified and / or smoothed becomes.

The Training according to claim 19 beats before that the Machine all measurement-relevant activities via a corresponding position control, In particular, laser control can run independently. This concerns the Distance to the track, the altitude the U-shaped Channel elements and the lateral position of the channel, as well as the displacement of the Channels during the Working process, namely warping during the forward movement. Thus, the survey for the production of the trench and others No longer work purely by hand and the accuracy and compliance Tolerances no longer a matter of an experienced excavator driver. Rather, the measurement of the trench is done automatically. Thus, the Installation of all surveying services both after manual operation, but preferably also fully automatic. This means that in fully automatic Mode the relevant dimensions, the distance to the track, inclination of the trench, distortion of the trench longitudinal, Distortion of the ditch in height, by a corresponding position detection device, in particular be determined by a laser control.

One embodiment a device for implementation the method for creating a drainage device next to the Track of a railway line is described below with reference to the drawings described. In these shows:

1 a single view of the device for digging a trench;

2 a section along the line AA in 1 ;

3 a schematic side view of the device for creating a drainage device;

4a a section along the line BB in 3 ;

4b a section along the line CC in 3 ;

4c a section along the line DD in 3 ;

5 a bunker wagon for the materials;

6 another bunker wagon for the materials with a transfer conveyor.

First, in the 1 and 2 the device for digging a trench shown in a single view.

On a track 1 a railway line is a work car 2 with a superstructure 3 traversable. Task of this work car 2 with an appropriate tool, it is by far the side of the track 1 a ditch 4 dig.

For this purpose, one is at the superstructure 3 of the work cart 2 laterally projecting, telescopic boom 5 intended. At the outer end of this jib 5 there is an excavation facility 6 , This excavating device 6 is as a milling device 7 in the form of an endless circulating band 8th with milling elements on it 9 educated.

Furthermore, a conveyor belt 10 intended. This opens with its front end above a - not shown - another work car 2 on the same track 1 or on a neighboring track. This conveyor belt 10 is pivotable about a vertical axis.

The operation of the trenching apparatus is as follows:
First, the telescopic boom brings 5 the milling device 7 the excavating device 6 in the correct lateral distance with respect to the track 1 , But it is exactly the place where the ditch 4 to be dug.

Then the milling device 7 pivoted by a corresponding drive down, with an inclination angle, as in 1 is recognizable. Through the endless circulating band 8th is by means of the milling elements 9 milled the soil, leaving the ditch 4 arises. It is essential that during this milling process of the work car 2 continuously moving forward. This means that during this forward drive of the work car 2 the soil continuously by means of the milling device 7 is milled and thus according to the forward drive of the work car 2 the ditch 4 is created. By a height adjustment of the boom 5 at his superstructure 3 of the work cart 2 and / or by the inclination of the milling device 7 can the depth of the trench 4 be predetermined. The control is preferably carried out automatically by means of a laser positioning.

That of the milling device 7 milled excavated material 11 gets the conveyor belt 10 given up. This conveyor belt 10 is pivoted about its vertical axis such that the front end of this conveyor belt 10 the excavated material 11 dumped into a corresponding reservoir. It can be the work car 2 to a behind or in front of the work car 2 to a work car 2 on a neighboring track or around a truck.

After getting into the soil 12 the ditch 4 has been introduced, there is a risk that the lateral soil 12 in the ditch 4 breaks. For this reason, following the excavation 6 a support device 13 for the side walls of the trench 4 intended. For this purpose, a U-profile with lateral support boards is used 4 , This is on a telescopic cantilever 15 arranged such that the U-profile in such a way in the trench 4 sticks out that the lateral support boards 14 at the side of the ditch 4 abutment and the soil 12 support. It is essential that this through the support boards 14 formed Verbau synchronously mitfährt. This means that immediately behind the excavator 6 the support boards 14 be tracked. Another special feature of the support boards 14 defining U-profile is that this only in the front area has a bottom (which the support boards 14 rigidly spaced), while the bottom is omitted in the rear area.

Because this bottomless area of the U-profile is gravel 16 fed. This is in a storage container 17 stored. This defines together with a transport device 18 in the form of a conveyor belt, a gravel application device 19 ,

The functionality is as follows:
The in the storage container 17 stockpiled gravel 16 is via the obliquely forward transport device 18 in the form of the conveyor belt the ditch 4 fed, in the area of the U-profile, which the side support boards 14 Are defined. Specifically, the gravel 16 supplied to that region of the U-profile, which has no bottom. This means that the gravel 16 directly to the underground of the excavated trench 4 is supplied.

However, located at the rear end of the two support boards 14 a transverse scraper 20 , This sweeps the passing below gravel 16 smooth and compact it if necessary.

After the ditch 4 in the soil 12 has been created and also the trench 4 has been laterally supported in the manner described above, now the individual elements of the drainage device can be introduced.

This shows how a filter fleece 21 is introduced. This is on the work car 2 on a roll 22 stored. The filter fleece 21 will from this role 22 unrolled and automatically digging 4 fed. The associated installation unit 23 which also have the side support boards 14 for supporting the trench 4 Defined, is about the superstructure by means of the boom in the form of the support arm 15 controlled.

Furthermore, a warehouse for the drainage or drainage pipes to be installed 24 intended. These are by means of a mounting device 25 the ditch 4 fed and installed there. The lateral supply of drainage or drainage pipes 24 on the work cart 2 takes place via a cross conveyor 26 ,

Finally, the ditch 4 still with backfill material 27 refilled. This purpose is served by a filling material introduction device 28 , In the backfill material 27 it can be gravel or other material. The filling material is from corresponding storage containers 29 by means of a transport device 30 in the form of a conveyor belt of the backfill feed device 28 fed. In this case, a plurality of layers of different materials can be installed if corresponding insertion devices are arranged in series one behind the other. If necessary, several transport facilities 30 operated in parallel.

The filling material introduction device is controlled and guided 28 via the automatic or semi-automatic superstructure. It should be noted here that, by design, the various superstructures can also be controlled together or in different dependencies. Basically, the most diverse variants are conceivable here. So it is also possible on one and the same work car 2 to arrange the most varied superstructures with their superstructure for the corresponding functions. But it is also conceivable that for each individual function each have their own work car 2 is provided. Also, several functions can be combined on a work car, other functional units can then on other work car 2 be arranged.

Finally, optionally, a re-compressor 31 or smoother be downstream.
