REINFORCEMENT METHOD OF FOUNDATION BASE DURING RECONSTRUCTION OF BUILDINGS AND STRUCTURES Russian patent published in 2019 - IPC E02D27/08 

FIELD: construction.

SUBSTANCE: invention relates to construction and can be used for reinforcement of foundations of barrel-type foundations and shell-type foundations during reconstruction of buildings and structures subjected to uneven precipitation and loads arising from their local soaking and freezing during operation. Method of reinforcing a foundation base during reconstruction of buildings and structures involves placing reinforcing elements parallel to each other in the base with formation of their end sections outside the outline of the foundation. First, leading wells are made at an angle to foundation, reinforcing elements are made by punching of semi-dry compacting sand-cement mix by means of pneumatic puncheon at its multiple driving to the leader well. Then, formation of reinforcement elements is installed under the sole of the cement-sand mixture base into the wells and cement-sand mortar is poured into the wells. Then reinforcement grid is laid in points of armoelements output, they are welded together and poured with concrete.

EFFECT: technical result consists in simplification of technology, increase of bearing capacity of foundation in flooded ground conditions, prevention of deformations of base and foundation, as there are no precipitations and effects of forces of frost heaving soil with simultaneous reduction of labor intensity and metal consumption.
