METHOD FOR REINFORCING BASEMENT SOIL Russian patent published in 2008 - IPC E02D17/20 E02D3/00 

FIELD: constructional engineering.

SUBSTANCE: invention refers to constructional engineering, namely to building of foundation beds and house footings. Method for reinforcing basement soil, includes placing reinforcing elements, layer-by-layer deposition of soil followed by grouting of filling compound, through outflows, to cavity pocket of reinforcing elements. Extensive hoses made of semipermeable polymer fabric or glass fabric are laid on piled soil as reinforcing elements. Hardening or consistent filling solution is grouted to hose cavity pocket until solution penetrates pores of reinforcing element fabric, and basement soil contact area is cemented, or until fabric is ruptured, and cells of circumferential soil are filled. Cement mortar or bentonitic clay solution can be grouted as hardening or consistent solution respectively. Filling solution can be grouted using injector tube mounted in hose cavity pocket. Plane or volume reinforcing cage, metal or synthetic, of strand or bar reinforcement can be placed into hose cavity pocket.

EFFECT: increased durability and reliability of basement soil, decreased dimensional instability of reinforcement.
