BACKGROUND OF THE INVENTION The present invention relates to a process for incorporating a trench filled with a self-curing suspension in geological conditions with high groundwater levels. It is desirable to use the invention to produce an underground conduit such as sewerage, water and gas pipelines. > The well-known manufacturing process is to store the individual parts of the pipe directly into the groove on the leveled bottom, respectively. on a concrete substrate or thresholds. The individual pieces are joined in a watertight manner. The groundwater level is maintained below the groove bottom. The walls of the groove are joined by a side spread, respectively. anchorage. Usually, the sheeting is done before digging the trench and before lowering the groundwater level.

It is known to store a long section of the duct. The difference with the previous one is that the long section of the pipeline is made up of pellets and stored by the assembly device at once. The groundwater level is maintained by pumping down the sediment or by means of needle filters which are placed in the groove.

The profiled, e.g., sewage drains are constructed such that the sheeting is carried out by monolithic or prefabricated underground walls. After the bottom and the ceiling have been fabricated, the underground walls form part of the channel structure. If they do not penetrate underground into an impermeable layer of soil, groundwater is reduced by pumping through the water or surface system.

Also known is a process for producing underground conduits, where the water flow is used to crease the grooves and prevent water from flowing! a sheet pile. In all of the aforementioned processes for the production of sewage, water, or gas pipelines, particular structures are required for the groove wall and if the sheeting structures do not interfere with the non-permeable subsoil, it is necessary to reduce the groundwater level in depth or surface manner.

Manufacturing processes are known where they are used for trench shoring! sheet, monolithic, or prefabricated underground walls, which support the armor to prevent groundwater inflow if embedded in an impermeable subsoil. In prefabricated underground walls, where a self-hardening cushion is used, the prefabricated elements do not need to be laid up to the impermeable layer of soil, but it is sufficient if the abundant cave is up to the impermeable soil. Thereafter, the cured mass of the self-curing suspension present in the sapod prefabricates serves as a seal.

The disadvantage of the above production processes is the high labor cost and increased investment costs.

Also known is a process for producing underground conduits, wherein the grooves of the underground walls do not deepen up to the impermeable subsoil. The soil remaining between the walls after the excavation of the groove is injected. If self-hardening sus-pension is used to crease the groove walls and also to thicken the walls, injection is done only after hardening. The hardening of the injection mass in the soil exhausts 218630 water from the space bounded by the underground walls and the injected soil. Further work, such as grooving, pipe installation and filling is carried out without the presence of groundwater.

This manufacturing process has disadvantages in increasing the labor intensities converted to meters of underground power and is expensive to invest. The process is only advantageous for large sewers.

The above mentioned drawbacks are eliminated by the process of production of the underground conduit according to the invention, according to which a pipe is inserted into the groove filled with the hardening suspension. The pipe sections are closed at both ends with shutters, whereby the pipe is filled with liquid. Supporting frames are placed above the groove to be secured by rods with rectification devices and bearing thresholds. A pipe is installed on the thresholds, its height is checked and the height is rectified. surface layer. In the connection of piping or shafts, the spaces in the hardened mass are heated out of the self-hardening suspension, removed the caps and drained the liquid. In the place of pipe shafts, the walls, bottoms and ceilings are decorated. The underground space at the piping connection point is filled with a self-curing suspension up to the level of the cover layer. Upon partial hardening of the self-curing suspension, it forms the remaining portion of the cover and surface layers.

By placing the pipe in a groove filled with a self-curing suspension, the production of the construction of the trench walls and the lowering of the groundwater level is eliminated. The support frames with rods and rectification devices allow the pipeline to reach the desired position. The piping connection or the concrete or reinforced concrete construction is carried out without the presence of underground water.

This process reduces production time, reduces labor, reduces investment and production costs per subway line.
