METHOD FOR PROTECTION OF SOLID SLAB REINFORCED-CONCRETE FOUNDATIONS ON UNDERMINED TERRITORIES Russian patent published in 2021 - IPC E02D27/34 

FIELD: construction.

SUBSTANCE: invention relates to construction, particularly, to methods of protecting foundations of buildings and structures erected in undermined territories. Method for protection of solid slab-type reinforced concrete foundations on undermined territories includes erection on soil foundation of compacted sand cushion, erection on sand cushion of solid slab reinforced concrete foundation, formation in the "foundation-foundation" system of the compensation layer, which prevents formation of cavities under the solid reinforced concrete slab foundation at subsidence of an underworked base. Solid plate foundation is made of two layers, upper bearing layer of reinforced concrete and lower layer of non-reinforced concrete, wherein lower layer of concrete slab foundation layer plays the role of compensation layer.

EFFECT: technical result consists in prevention of formation of cavities under a solid reinforced concrete slab foundation with subsidence of undermined base.
