Description

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

In addition to the tracks of railway lines are often drainage facilities. These are trenches parallel to the track with water-bearing fillings as well as drainage or drainage pipes.

So far, such drainage devices are made by using conventional construction equipment, especially excavators, as well as means of transport, especially railroad cars or trucks. The excavator first lifts out of the ground a trench parallel to the track. Then drainage or drainage pipes are laid in the excavated trench. Finally, backfill material is entered. A filter fleece can also be introduced.

The disadvantage of this known method for creating a dewatering device is that it is performed discontinuously, namely cyclically. The individual workloads are correspondingly high. The individual work steps are not particularly effective due to the cyclic design and do not make it possible to implement the sequence of work steps in a continuous sequence.

Furthermore, a so-called shoring is required by this construction at greater depths, which supports the side walls of the excavated trench. This shoring must be installed in the excavation by means of an excavator or other lifting device. According to the progress of work, the shoring must then be removed again intermittently. Again, due to the cyclic working process long lead lengths of Verbaus are required. Because it must always held the length of a work cycle, installed and removed again before the next cycle can start with the held shuttering quantity. Another disadvantage of the cyclic construction is that it can be introduced only after the preparation of the excavation. This, however, the risk of collapse of the lateral soil of the trench is up to the wrapping of the Verbaus. However, this means that it must be reworked continuously in the trenches to remove the collapsing soil.

Often, a filter fleece must be installed to ensure the filter stability of the built-trench material against the upcoming soil. This requires another, manual work step in the cyclic conversion process.

After all, the survey for producing the trench has so far been purely manual work. The accuracy and compliance with tolerances is a matter of an experienced excavator driver and can not be automated.

The DE 42 34 442 A1 shows a method for introducing bottom concrete in pipe trenches during pipe laying work on railway lines. For this purpose, a work train is provided on which all necessary construction equipment and materials are located. To excavate the trench next to the working track, an excavator progressively moves backwards on overreachable railway carriages and loads the railway carriages released in front of the excavator with the resulting excavated trenching material. After excavating the trench, the concrete is poured into the trench. For this purpose, a dry mortar silo and a water container is stored on the work train. The dry mortar is mixed with the water shortly before processing and fed to the pipe trench by means of an inclined chute or a conveyor belt. After filling the pipe grave section with the concrete floor, the entire work train is moved so that the next section can be edited.

The DE 101 02 328 A1 shows a puller for a platform edge foundation. The basic principle is that the peeler is moved on the tracks of a track body. The puller has a feed chute with a filling opening for concrete. Below this feed chute has an outlet. A second feed chute can supply gravel and / or gravel. Between the feeding of the concrete through the first feed chute and the feeding of the gravel and / or gravel through the second feed chute is a supply channel for a lateral formwork to laterally support the introduced concrete and to prevent sagging of the foundation.

The US 5 435 081 A shows a device for loosening the ballast in railway lines. For this purpose, a laterally projecting arm is provided on a work car, which has a corresponding tool at its outer end.

The US 4,713,898 A shows a work car for track distances, by means of which the side of the track a ditch can be excavated. For this purpose, the work car on a laterally pivotable boom. At the front end there is a trench cutter. This is pivotable about a vertical axis.

The invention has for its object to provide a fast and effective method of creating to create a drainage device next to the track of a railway line.

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

As a result, a method is provided with a corresponding machine for the rapid and effective production of a drainage device next to the track of a railway line. The machine is rail-bound and independent in its handling and operation. The machine is solely for the creation of the drainage facility next to the track of a railway line. This machine for carrying out the method can perform all the necessary steps for the production of drainage ditches continuously and in sequence. These are first the excavation of the trench, the laying of the drainage or drainage pipes, the possible installation of a filter fleece and the installation of all filling layers such as gravel, drainage gravel, covering material or the like. The machine performs all consumables, running in one or more layer performances be transported with them and transported automatically or semi-automatically to the installation site. Due to the design, the corresponding railway carriages with their superstructures can be controlled jointly or in different dependencies. Depending on the design, they can also be installed as a common work car. After excavation of the trench, the lateral soil of the trench is supported by lateral support boards. These support boards are preferably made of sheet metal or steel. This is especially at greater depths of advantage, where the risk is very large that soil collapses. The basic idea is thus that during the propulsion of the work car an automatic entrainment of a Verbaus takes place. This means that the shoring must be held only for the length just to be processed and that this shoring is continuously carried along the working speed of the continuous process. For this purpose, the support means is preferably arranged on a telescopically projecting arm, which can position the support boards exactly in the excavated channel. An essential aspect is that these lateral support boards are carried synchronously with the forward drive of the work car. This means that immediately after digging the trench, the support boards come into action and protect the trench against lateral collapse. These support boards thus define a so-called ongoing shoring. The lateral support boards can be defined by a U-shaped profile. The floor (or ceiling) thus forms the rigid structural connection between the two lateral support boards. This floor or the ceiling does not need to extend over the entire length of this support means. It is sufficient that the soil is formed only over a partial length. Where there is no soil, then, for example, the gravel for covering the bottom of the trench can be introduced. Are then the two lateral support boards still connected by a horizontal, web-like scraper, the introduced gravel can be smoothed and possibly compacted.

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 excavating both in layers of earth and optionally in rock layers, depending on the needs and requirements of 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 separate, heavy machine on the work car created which 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 embodiment proposes according to claim 3, that the excavated material by the excavating device is milled off. It is thus a track-guided or track-bound trencher. The milling has the advantage that it ensures a continuous flow of work in the sense of continuous forward movement of the work car.

The technical realization of the trencher provides according to the embodiment in claim 4, that is used as a milling device endlessly circulating belt or an endlessly circulating chain or the like., Which is equipped with cutting elements. The advantage of such a milling device is that a continuous excavation is possible up to great depths of several meters and with large lateral distances to the track of several meters. In this case, the milling device is preferably replaceable. By different width milling devices can thus be excavated in a simple way different width trenches.

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

A preferred development proposes according to claim 6, that the excavating device is arranged on a transversely to the direction of movement of the work carriage telescopic boom. This projecting boom, at the end of the excavating device, in particular the milling device is, has the advantage that large distances between the track and the trench to be excavated can be bridged, and indeed distances of several meters. The milling device can be pivotable in order to avoid obstacles in the form of masts, for example. The stable guidance of the excavating device is achieved by the compact design of the work cart with the corresponding structure for the excavating device. The weight of the unit described above serves to counteract the overturning moment of the projecting excavating device. The weight can also optionally be chosen variable, for example, by the work car is equipped with additional weights. Thus, a continuous execution of all operations in one pass is guaranteed even at a long time distance to the track.

The development according to claim 7 has the advantage that in a technically simple way very large depths of several meters can be excavated. In addition, a possibility for avoiding obstacles is created. Thus, the telescopic arms can hold the milling device in its required position in terms of height and direction and in terms of inclination by a corresponding pivoting movement.

The interchangeability of the excavating device on the work cart according to the embodiment 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 other tools can be grown as excavating equipment as an optional additional solution, such as 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 feeding of the excavated material to the work car can be carried out according to the embodiment in claim 10 by means of a conveyor belt. Thus, the track-bound or track-guided excavating device is combined in particular in the form of a trench cutter with a conveyor belt technology to the effect that a direct discharge of the excavated material on a connected conveyor belt in a continuous operation.

Preferably, according to the embodiment of claim 11, the conveyor belt is pivotable about a vertical axis. In this way, the excavated material can be loaded both on railway wagon head or even on a neighboring track vehicle or a road truck.

The development according to claim 12 provides a bunker for the backfill material. The trolleys deliver the conveying material from the bunker trolley to conveyor belts. If required, several bunker cars can be coupled in series in order to be able to transport sufficient backfill material. The development thus provides that the work cart has a storage container for the filling material, which is introduced into the trench. By means of a corresponding transport device or by means of appropriate transport facilities, the filling materials, such as gravel, the trench fed. It can also be installed several layers of different materials. The materials of the different layers are led by conveyor belts. If required, several conveyor belts can be operated in parallel.

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

The development according to claim 13 proposes the previously mentioned variant in that the gravel abandoned to the bottom of the trench is smoothed by a scraper and optionally compacted. This means that initially the soil of the gravel or the like. Is abandoned, the entrained scraper stripping off the gravel and precompressed if necessary. This thus represents a possibility to feed the excavated trench the soil material without much effort. It is only necessary that from a corresponding storage container of the work cart the gravel stored there, for example, by means of a conveyor belt is fed to the trench.

As already stated above, the scraper according to the embodiment in claim 14 is preferably formed on the support boards of the current Verbaus for supporting the lateral soil. This represents a technically simple measure on the one hand for supporting the lateral soil and on the other hand for stripping the abandoned gravel.

A further development proposes according to claim 15, 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 or drainage pipes can additionally serve as a running shoring for the 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 development according to claim 16 proposes the automatic feeding of a filter fleece. The filter fleece is stored on the work cart in the form of a nonwoven roll and can be rolled from there and automatically fed to the installation site.

The development according to claim 17 proposes that at the end of the input backfilling material is recompressed and / or smoothed.

The development according to claim 18 suggests that the machine can perform all surveying relevant activities on a corresponding position control, in particular laser control independently. This concerns the distance to the track, the height of the U-shaped channel elements and the lateral position of the channel, as well as the displacement of the channel during the operation, namely the warping during the forward movement. Thus, the survey for the production of the trench and other work is no longer pure manual work and the accuracy and compliance with tolerances no longer Thing of an experienced excavator driver. Rather, the measurement of the trench is done automatically. Thus, the device allows all surveying services both after manual operation, but preferably also fully automatic. This means that in the fully automatic mode, the relevant dimensions, the distance to the track, inclination of the trench, distortion of the trench in the longitudinal direction, distortion of the trench in height, are determined by a corresponding position detection device, in particular by a laser control.

An embodiment of an apparatus for carrying out the method for creating a drainage device next to the track of a railway line is described below with reference to the drawings. 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 supporting 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.
