PROCESS FIXING SLOPE OF SOIL FOUNDATION TRENCH Russian patent published in 2003 - IPC

FIELD: civil engineering. SUBSTANCE: in agreement with proposed process tubular injector at least one meter longer than depth of foundation trench is driven into soil base prior to stripping of foundation trench, reinforcing rod is placed into tubular injector, lost tip is pushed by rod, injector is removed from hole pierced in soil, hardening and reinforcing solutions are injected into soil under pressure, soil is broken hydraulically along directions of cracks formed by knives of injector, head pressure is reduced to pressure of soil breaking, injector is sunk into soil for the second time, secondary hydraulic breaking of soil is carried out in same manner, cruciform anchor is formed in slope of soil foundation trench. After hardening of solution thrust plate with tension gear is superimposed across dug section of slope on which cruciform anchor is pulled with fixing. After fixing slope of first story next story is stripped and all operations are repeated in way similar to fixing of first story. Anchors are arranged at angle to slope both in vertical and horizontal directions. As anchors are arranged thrust plates are joined to form anchor wall-guarding structure. EFFECT: simplified technology of formation of vertical fixing members, reduced cost of fixing and raised stability of slope of soil foundation trench. 4 cl, 10 dwg
