Description

The invention relates on the one hand to a method and others on the one hand a device for laying several oneself side by side and overlapping tubes in Create a longitudinal direction below the surface of the earth tunnel-like tube according to the features in the upper understood the claims 1 and 2.

It is known pipes that are used to transport liquids ten or gases or pipes in which supply cables, in particular high-voltage cables, laid should be next to and / or one above the other in tunnels to pull in like tubes, which are created there the one where the pipes are under water, under streets or must be led under buildings, d. H. wherever none from the surface of the earth from above accessible trenches can be made. Such Tubes are also often not straight, son  are curved, with horizontal and vertical Can overlap curvatures. The length of such tubes can be several hundred meters. you will be mostly manufactured in the prepress process and consist of Concrete.

If you want to pull a single pipe into such a tube hen, a suitable feed device must first for example a rope, a cable or a chain the tube will be relocated. Then the pipe with connected to this feeder and then through the Tube pulled. This effort has to be repeated for each pipe be picked up, unless it succeeds for two or also several pipes be a suitable feeder to sit down, which can be shifted through the tube. Regardless of whether the pipes one after the other or several pipes, for example two or three pipes, are drawn into the tube at the same time but the risk that the installation position of the pipes is not can be ensured without complex corrective measures can, because they may have twisted when moving in, d. that is, they are not parallel to each other. Is too to take into account that for economic considerations out a tunnel created below the surface of the earth like tube usually in terms of their entire Cross-section should be used. Twisted pipes but do not allow such use. The not exact The parallel position of the pipes is particularly significant Lich disadvantage if high-voltage cables in the pipes should be relocated to a precisely prescribed Minimum distance must be that of the height of the transporting electrical energy is dependent. The So far, however, the exact minimum spacing of the pipes can with the known possibilities not without considerable Effort can be guaranteed.

DE 39 31 058 C1 describes a method for laying a pipe system intended for the transport of media tion system with an outer cladding tube and at least an inner medium tube arranged in the cladding tube knows. Between the cladding tube and the medium tube are Ab stand holder provided. To un this piping system ter using known welding or joining technology It is envisaged that it can be installed quickly and easily hen that first the cladding tubes to one another Envelope pipeline of specified length welded or ver be bound. Only then will the media tubes also be with each other to an essentially equal length Medium pipeline welded or connected and in the already laid cladding pipeline, keeping one free predetermined radial space inserted.

The invention is accordingly based on the object Method and device for laying pipes in a tunnelarti created below the earth's surface to create a tube that is economical the exact drawing in of any number of Pipes in precisely prescribed relative positions up to the on ensure construction position.

The solution of the procedural part of this task be stands according to the invention in the characteristics of Pa Features listed in claim 1.

This procedure involves initially all in one tube pipes to be pulled in exactly in front of one end of the tube able to position that in their installation position corresponds to the tube. Then this will be Aggregation while maintaining the rela tive position of the tubes completely into the tube up to Moved to the installation position. Now be the areas on the circumference of the pipes and between the Tubes and the inner surface of the tube with a Fixing compound, such as concrete, poured on the finally hardens and thus leaves the pipes immovable geared up.

The particular advantage of the method according to the invention lies in the fact that it is independent of the length a tube as well as from its horizontal or vertical Curve course is possible, the relative position of the pipes to be followed exactly, so that especially in the pipes high-voltage cables laid the prescribed min distance and the cross-section of the tube ma can be used ximal.  

With regard to the objective part of the task be the solution is in the characteristic features of the Pa claim 2.

Then the pipes are oriented on one link-like tube feed unit outside the tube. After this orientation, the pipe feed unit forcibly moved through the tube until that on the Pipe feed unit, pipes are in their installation position achieved. The pipe brackets are designed in this way and distributed into the pipe feed unit in a link-like manner tegrates that the pipes - based on the cross section of the Tube - with a maximum possible number without friction contact with the inner surface of the tube through this can be relocated. The limited lateral mobility of the tubes on the tube supports allows that the tubes with vertical and / or horizontal curvatures according to the tube to the side, up or down can move without ultimately their can change predetermined relative position.

The tube feed unit can be hanging in the tube or to be positively guided. It is important that the pipe-in traction unit is positively guided to by the pipe supports supported tubes according to the curvature to be able to move the tube through it.

The link-like tube feed unit has the installation positions reached the pipe, it is locked and remains together with the tubes in the tube, d. H. it will be if covered by the fixing compound. So seen the pipe feed unit as well as its positive guidance trained that it is simple, but nevertheless the safe retraction of the tube package or tube guaranteed in the tube.  

An advantageous embodiment of a pipe feed Unit consists in the features of claim 3. Da after a rail string is fixed on the bottom of the tube on which transport trolley, preferably rolling, are relocatable. Rolling therefore in order to get one as possible struggle to generate resistance. The soothing forced guidance allows a simply constructed track, which ultimately remains in the fixing compound. The transport wa genes are limited vertically and horizontally hinged together coupled, so that the curvature of the tube ent can be taken into account. The number of Dolly and its length is based on the length of the pipes as well as the curvature or the degree of each Curvatures of the tube stopped.

It is conceivable that the ver on a rail track storable tube feed unit with a self-drive ver is seen, but not when introducing the fixing compound is embedded with. Also a cable or chain drive is conceivable. It is more economical because it is cheaper however, the tube feed unit according to claim 4 with a rope, especially a steel rope gladly. A rope can be comparatively easy in the longitudinal direction direction of the tube to be routed.

An advantageous design of the transport carriage of the pipe Feed unit is in the features of the claim 5 seen. The side member can preferably be made of egg nem square hollow profile exist. This training reduces the cost of materials and conveys the length wear an elastic deformability, which, especially when cornering, preferably in one the vertical cornering, the independent Adaptation of the tube feed unit to the curvature the tube without constraints.  

The couplings are on the end faces of the side member means the trolley in the form of a clutch fork one end and a coupling tab on the the end face provided. For connecting two trans portwagen becomes the coupling bracket of a transport vehicle into the coupling fork of the neighboring trolley introduced and then these parts through a dome lungs bolts connected to each other in a tensile and compressive manner. Whether it is conceivable that the trolley with three or To provide multiple pipe brackets, it is according to the Invention advantageous, each in the middle of a trans port wagon as well as shelf-like pipe supports at one end provisions. Such pipe brackets make it possible depending on their configuration pipes with different large cross-sections securely and at appropriate distances to transport. In the context of the invention, it is sufficient only a trolley in the middle and at both ends with a tube equip brackets. All other transport cars are only equipped with two pipe brackets, the one in the middle and one end of the dolly are provided. In this way, all pipe holders are distributed evenly apart arranges.

The pluggability and screwability of the diver Sen elements of the pipe brackets according to Pa claim 6 is associated with the advantage that at Orientation of the pipes on the pipe feed unit outside the tube one after the other, selectively the pipe brackets can be placed. This is ins This is particularly advantageous if the pipes have lengths of several hundred meters. According to the invention but also that the pipe brackets visible their vertical and hori carrying the pipes zontal elements are designed as welded structures. in the In the context of this embodiment, it is then advantageous  if the adjacent to the inner surface of the tube Pipe bracket elements (stems) can be swiveled, if necessary or can be plugged in so that the pipes can be easily attached to the Pipe brackets can be placed.

A particularly advantageous embodiment of a pipe bracket is in the features of claim 7 ge indicates. Each pipe bracket can be installed on each level be built up, the higher lying Shelf supports together with the pipe rack assigned to them len make sure that the pipes in the below horizontal pipe shelves limited transverse movement, d. H. since are oriented and upwards. The single ones Elements preferably consist of hollow profiles, which can be positively plugged together and screwed can. As a result, the individual pipe racks can also Cross sections of the pipes can be adapted largely freely. Although the pipe shelves can be formed by elements which represent the receptacles for the pipes, but it is also conceivable that the inner surface elements of the tube shelves adjacent to the tube from to lower-facing elements of the higher ones Shelf supports are formed. This is particularly evident which is advantageous in those cases where the pipes are have higher weight and therefore not yet over the The upper edges of the cantilever from the pipe shelves upwards the elements must be relocated. In this case the height of the outer elements when inserting the pipes saved.

The flawless guidance of the trolleys on the rails strand is useful due to the characteristics of Pa claim 8 ensured.

To ensure that even with smaller radii of curvature of the tube If possible, clean the tube feed unit in the tube  To ensure low-exercise, the characteristics of Pa claim 9 are used. These thrust rollers are, for example, only every fourth or fifth trans assigned to port wagons. You can then look at the inner one Support the surface of the tube in a rolling manner without the Get pipe supports in contact with the tube wall.

An advantageous design of the rail track exists in the features of claim 10. Such an off Education allows the casters to rest on top flanges the U-profiles, the support rollers on the Un flanges and the guide rollers on the webs of the U Can roll profiles.

For guiding the pipe infeed unit Ropes are, according to claim 11, rope guide stations on various rail bars, especially dismantled cash, fixed. Can be dismantled because every cable guide tion station when the pipe feed unit approaches builds and is not embedded in the fixing compound. The Rope guiding stations preferably comprise two um vertical axes rotating rope pulleys with circumferential towards rope grooves. These form a closed rope fen ster for the pull rope. In certain applications it is but also conceivable that the rope guide stations Rail bars are not releasably assigned. Here who the rope guide stations from the dolly run over and after reaching the installation position with embedded in the fixing compound.
