High-rise building foundation strengthening protection structure and construction method thereof

Abstract

The invention discloses a high-rise building foundation strengthening protection structure and a construction method thereof. The high-rise building foundation strengthening protection structure comprises a plurality of cast-in-place piles which are distributed on the periphery of the bottom of a high-rise building in the circumferential direction of the high-rise building, a reinforced concrete terrace which is laid on the ground outside a foundation of the high-rise building, is used for pulling and combining the foundation and the cast-in-place piles into a whole and wraps the tops of the cast-in-place piles and exposed parts of the foundation, and concrete circumferential beams which are arranged on the periphery of the cast-in-place piles, wherein the distances between the concrete circumferential beams and the tops of the cast-in-place piles are preset depths, and the concrete circumferential beams are connected to the outer sides of the cast-in-place piles in a supported mannerand used for exerting lateral prepressing stress on the cast-in-place piles. The high-rise building foundation strengthening protection structure is simple and stable in structure and easy and rapid to construct; soil on the periphery of the high-rise building is convenient to excavate, safety requirement during excavating construction of the soil on the periphery meets an engineering specification, the peripheral engineering construction schedule is advantageously accelerated, the using function of an exiting high-rise building is not affected, and the migration work of the high-rise buildingis avoided.

Description

technical field [0001] The invention relates to the technical field of building foundation reinforcement, in particular to a towering building foundation reinforcement protection structure and a construction method thereof. Background technique [0002] In the construction of urban roads, new roads inevitably pass through some important high-rise buildings, such as high-voltage transmission towers, high-rise water towers, etc. Usually, in the construction design, it is chosen to keep the designed road away from the existing important towering structures as much as possible. However, when continuous or multiple high-rise buildings (such as: continuous high-voltage electricity towers, etc.) Investing a lot of money and manpower and material resources is also likely to bring hidden dangers to construction safety. Therefore, it is necessary to reinforce and reinforce the foundation of the existing towering structure, and then excavate the soil around the foundation of the towe...
