摘要
FIELD: construction.;SUBSTANCE: invention relates to transport construction and can be used for reinforcement of road bed of automobile roads in places of arrangement of culverts. Method for strengthening the roadbed in places where the culverts are installed includes the creation of a spatial frame structure by layering the geocell system with filler from crushed stone-sand and/or gravel-sand mixtures with a continuous grain size distribution of grains not exceeding 80 mm, which forms a protective prism around the pipe. First layers are laid at the pipe body, the subsequent layers are above them, and the last layer is laid above the pipe body to the width of the road bed, with each subsequent layer being laid with a slight offset to the pipe axis.;EFFECT: technical result consists in increasing the resistance of the soil mass to compressive and shear stresses in places where the culverts are installed, improving the quality and efficiency of the work carried out.;1 cl, 3 dwg
