METHOD OF FIXING AND ENHANCING THE CARRYING CAPACITY OF WET FINE GRAIN SOILS OF RUNNING TYPE UNDER BASES AND FOUNDATIONS OF BUILDINGS AND STRUCTURES Russian patent published in 2016 - IPC E02D3/12 

FIELD: construction.

SUBSTANCE: invention relates to construction, particularly, to techology of fixing the wet fine grain soils of running type under bases and foundations of buildings and structures. Method of fixing and enhancing the carrying capacity of wet fine grain soils running type under bases and foundations of buildings and structures involves deepening of injection wells through which low-viscosity solution is fed with the help of injectors under pressure. To increase the radius of propagation of the injection low-viscosity solution additionally at the distance of L, for example at least two side wells are drilled on both sides from 3 to 3.5 m from the injection well, into each of which device for pumping water, for example, perforated pipe, covered with a microporous material and connected to vacuum pumps is lowered, and water is pumped out of pores of injected wet fine soil, reducing resistance of interstitial water to injection low-viscosity solution, fed by the injector from the injection well, running in one time mode with vacuum pumps.

EFFECT: technical result consists in increase of radius of propagation of the injection solution, and hence, pitch between injection wells and distance between rows of wells, reduction of material consumption and labour intensity of construction.
