FIELD: construction.SUBSTANCE: invention can be used in the reconstruction of buildings and structures with a strip foundation, a pile grillage or a grillage-free pile foundation, due to increased loads on the foundation. The method of reinforcing the foundation during reconstruction involves creating galleries under the foundation base of the existing building and driving multisectional piles from the galleries with jacks under the foundation base, with the abutment on the existing foundation plate, concreting the pile cavity and forming the pile head. The method is implemented under conditions where the total pile driving force exceeds the weight before the reconstruction of the building arranged either on a pile grillage, or on a strip foundation, or on a grillage-free foundation.

Driving the piles is carried out from the galleries arranged at an appropriate stage under the bottom of a grillage or a strip foundation, or under the building elements, which are used as supporting elements at the abutment of jacks. At the initial reinforcement stages, the carrying capacity of the soil base under the foundation is used, taking into account its weakening by the galleries, and at each subsequent stage the load-bearing capacity of the pile grillage with the structures built thereon is used, taking into account the weakening of the ground base by the galleries for the piles driven at the next stage.EFFECT: reinforcement of the foundation, when the total pile driving force exceeds the weight of the building before reconstruction, increasing the carrying capacity.6 cl, 2 dwg
