METHOD FOR CONSTRUCTION OF PILE FOUNDATION Russian patent published in 2016 - IPC E02D27/48 

FIELD: construction.

SUBSTANCE: invention relates to construction and can be used in construction of buildings and structures on wooden piles. Erection method of pile foundation includes grid device on prepared soil base, step-by-step pressing of piles with jacks as erection of bearing structures of buildings proceeds, concreting cavity of pile and formation of pile head. In installation places of piles step-by-step created tunnel, and pressing of piles is carried out from tunnel driving arranged at appropriate stage under grid with stop jacks in foundation frame. At initial stages of erection is load-carrying capacity of foundation soil under grill for attenuation of drift ways, and on each following stage is used carrying capacity of pile grid with erected on it structures with account of attenuation of foundation soil under grid by galleries at pile, trapped at next stage.

EFFECT: technical result consists in expansion of sphere of using method, in particular, in construction in constrained conditions, simplification of technology, reduction of cost and reduction of material consumption of working at pressed piles, as well as in simplification of works on executing assembly interface of pile with grill or another support element.
