METHOD OF FOUNDATION CONSTRUCTION AND HOW IT IS SET UP Russian patent published in 2018 - IPC E02D27/01 

FIELD: construction.

SUBSTANCE: method of compound foundation construction includes preparing the foundation pit bottom for the sole of the load bearing structural component of the foundation, producing the structural component of the foundation, and forming a load bearing ground structural component of the foundation. The foundation is compound and is made of load bearing ground and prefabricated structural components. The soil is extruded by the shock action of a falling heavy rammer with given geometric parameters of the sole of a plane-convex rotation shape and simultaneous concomitant formation of a densified core in the form of a circular cone of a load bearing ground structural component of the foundation. A precast reinforced concrete foundation slab with a coaxially located and rigidly connected rod concrete post with a sole in the shape of rotation and geometric parameters of a rammer which is equivalent to the sole is laid in a deepening of the base of the load bearing ground structural component of the foundation. The precast reinforced concrete frusto-conical shell is mounted coaxially on the foundation slab on the distribution layer from the freshly applied cement-sand mortar. The anti-corrosion ring of the base of the shell cone is rigidly connected to the foundation slab by performing monolithic reinforced concrete "rivets" of reinforcing anchors and cast concrete on a shallow aggregate. The upper frusto-conical end of the support column is rigidly connected by embedment with cement-sand mortar in a cylindrical cavity coaxially located in the hard disk of truncation of the shell of the bearing precast structural component of the foundation.

EFFECT: increased stability, bearing capacity of the foundation, quality, reliability, technical and economic efficiency and competitive ability of the foundation, consisting of a single facility of load bearing ground and structural components, providing new conditions for interaction of the composite soil foundation with its soil-compacted foundation.
