METHOD TO CREATE SPATIAL STRUCTURES FROM HARDENING MATERIAL IN SOIL MASSIF Russian patent published in 2012 - IPC E02D3/12 

FIELD: construction.

SUBSTANCE: method to create spatial structures from a hardening material in a soil massif includes formation of a wall, arrangement of a longitudinal stress riser on its wall, locking of the upper part of the well with isolation of an injection zone, formation of a vertical rupture plane in the massif and its filling with the hardening material. The hardening material is soaked from 7 to 24 hours. The well is cleaned at this age from the hardening material within the injection zone. A cutter is turned at the specified angles in the range from 0 to 360°, and structural elements of the required shape and dimensions are formed. Then they are combined in the base of building and structure foundations, uniting them in plan and along height into spatial structures for joint operation.

EFFECT: reduced material intensity and energy intensity, improved quality of works, higher reliability of weak soils reinforcement in foundations of buildings and structures.
