DE8804826U1 - Self-propelled gun for carrying construction equipment - Google Patents

Description

The invention relates to a self-propelled gun, which is characterized in that a self-propelled carrier gun travels over a pipe or cable trench. Until now, it has been usual to carry out all work on the above-mentioned construction projects from the side of the trench. Working in deep trenches (e.g. when building canals) is often complicated and time-consuming.

The technical advance of the invention is that it is now possible to carry out work in deep trenches not only from the sides and inside the trenches, but only from above and beyond the trenches. It is therefore possible that the trench no longer has to be entered during pipe-laying work. One consequence of this is that the width of the trench can be concealed.

The sequence of the method according to the invention is described as follows using the self-propelled carrier carriage shown here as an example - using the example of a canal construction.

First, a tar cutting machine with two saw blades at the required distance is attached to the support carriage and the tar covering is cut open. The trench is dug using an excavator, which also lifts the trench shoring. If the ground is unsuitable, it may also be possible to use a trench cutter, which is attached to the support carriage. Once the pipe trench has been dug, a pipe support - previously made of precast concrete - is lowered using the pipe laying machine with the telescopic arm and lowered to the desired level by turning the slewing ring. The operator of the support carriage determines the desired level by placing ^a laser target in the pipe support. The angle mirror can be used to convey the glow to the operator. Once the support has been installed, the sewer pipe can be inserted into the trench using the pipe laying machine. The rear pipe support represents the socket of the previously laid pipe, the front one the precast concrete part. The pipe laying device is most effective for pipe diameters from DN200 to DN400. Once the pipe has been installed, the sand or concrete for the pipe support can be poured, packed and sealed. After

Once the pipe casing has been installed in the same way, the vibrating plate is attached to the hook of the trench laying device, lowered and the trench filling material is compacted. The installed shoring plates are pulled from the support carriage. Once the trench has been filled, the tar gap is installed. Tar machines can be attached to the support carriage, as can many other devices.
