METHOD FOR PREPARATION OF BASE OF STRUCTURE ON WEAK GROUNDS Russian patent published in 2020 - IPC E02D27/26 

FIELD: construction.

SUBSTANCE: invention relates to construction and can be used in building foundations on weak soils and embankments of transport facilities. Method of preparing the foundation of the structure on weak soils involves excavating the excavation, filling the soil cushion with the layer-by-layer seal, laying the geoweb and fastening the ends of its panels to the anchoring elements. Before laying the geoweb in the center of the pad, a linear crossbar is placed, the soil is poured over the geoweb from the device of the loading prisms above its end sections, then the crossbar is lifted above the surface of the pillow, heating the geoweb to temperature providing occurrence in its material of heat shrinkage stresses, measuring the force required to hold the beam at a given height, after reaching the specified value of force, traverse is removed and soil is filled and compacted above geoweb between loading prisms.

EFFECT: technical result consists in improvement of efficiency of reinforcement of soil cushion, namely, improvement of its stability and reduction of settling of erected structure due to prestressing of reinforcing layers.
