FIELD OF THE INVENTION The invention relates to construction and may find application in the field. construction of the main Tpy6ont OBOODs in the waterways.

There is a method of laying an underground pipeline, which consists in extracting a trench, laying a pipeline into it, fixing it to the bottom of the pipeline with anchors and filling Tl. However, providing a high-quality fixing of the pipeline in soils of medium and high density, the method is inapplicable on very dense rocky soil because inability to immerse in. these are anchors.

The closest technical solution to the present invention is a method of laying an underground pipeline, consisting in taking a trench, laying a pipeline in it, hanging weighty reinforced concrete pockets on the pipeline, ensuring that they are supported by flat bottom surfaces on the bottom of the trench, backfilling of pockets and trench. ,

The disadvantage of this method (is the relatively high cost of work due to the use of a significant number of pockets of reinforced concrete.

The purpose of the invention is to reduce the cost of work by reducing the consumption of concrete.

This goal is achieved in that according to the method of laying the underground pipeline, plates are used as pockets, and before they are mounted on the pipeline, the bottom of the trench is leveled and covered with a layer of adhesive material.

The method of constructing an underground pipeline is as follows.

The trenches are torn off at its sites characterized by cohesive properties (sandstone, limestone, rock, etc. hard rocks, the bottom of the trench is carefully leveled, and then the pipeline is laid at the bottom. The pipeline-free surface is covered with tacks of adhesive material, for example , cement-based, and on these places are placed reinforced concrete slabs, which are connected to each other by the forces imposed on the pipeline themselves. At the same time, the slabs act as pockets for reinforcing their backfill. closing pockets and trenches are filled up.

Thus, as a result of the fact that the extensible functions are in addition to ma-. the slabs also perform adhesion forces between the surfaces of the trench bottom and the slabs, and it is possible to perform slabs-pockets of reduced mass, which leads to a decrease in the consumption of concrete.
