FOUNDATION REINFORCEMENT METHOD Russian patent published in 2005 - IPC

FIELD: building, particularly for reinforcing foundations built on soil base in the case of increased loads applied to them and in the case of soil structure failure.

SUBSTANCE: method involves excavating foundation pits, compacting soil by placing reinforcing members, namely microtunnels filled with hardening material under foundation along the full length thereof. Microtunnels are formed by pushing and compacting soil with the use of cone with through channel moving under base. Hollow tie rod is arranged in cone channel. Hardening material is fed through tie rod into microtunnel formed after the cone. Cone axis is located so that compacted soil boundary adjoins foundation base. Distance between cone axis and foundation base is determined from a given relation.

EFFECT: possibility of soil compaction without welding operation use; increased load bearing capacity of foundation and building structure stability due to increased load-bearing capacity of soil.
