FIELD: construction.SUBSTANCE: construction method of pile-slab foundation of high-rise building includes excavation of pits and piling field with subsequent concreting of foundation slab. Piling field is constructed over the entire area of the pit made of bored piles of the same length, after that the resistance of piles is increased in the central zone of the piling field along the lateral surface by injecting the cement, polymer or polymer-cement solution along the lateral surface of pile.EFFECT: increase of the resistance along the lateral surface of pile and load-carrying ability of the foundation under the high-rise building, provision of load transfer between piles, reduction of labour coefficient of its construction and materials consumption.1 ex, 2 dwg |
