FIELD: machine building.
SUBSTANCE: method includes underground installation of a pipeline in a wide trench with gentle slopes. At the same time to avoid contact of the pipeline with a wall and a bottom of the trench and a filling soil, elastoplastic elements are installed (laid) onto the external surface of the pipeline in the form of bags or reservoirs of various geometrical shape with dimensions (0.2 ÷ 1.5 m) x (0.4 ÷ 3.0 m), filled with chippings of non-compressed glass-fibre materials or foam propylene, foam rubber materials, sand or peat. Installation of a rock shield into the pipeline is provided. Then the trench is filled with crushed stone. Loads at the pipeline are compensated and pipeline oscillations are damped by properties of elastoplastic elements and accordingly by capability of free displacement and deformation of the pipeline in the trench.
EFFECT: elimination of pipe wall damage or insulation of a pipe from the filling soil.
