Abstract

The invention discloses a structure for controlling foundation pit deformation and a construction method. The structure comprises an enclosure body arranged along the periphery of a foundation pit, wherein an inner support is arranged on the inner side of the enclosure body, a continuous underground wall is arranged in the foundation pit and is perpendicular to the long edge direction of the foundation pit, and the underground wall is composed of a lower reinforcement underground continuous wall and an upper plain concrete underground continuous wall. According to the structure, the underground wall is used for controlling foundation pit deformation, the problem of damage of deep foundation pit deformation to the surrounding environment is solved, the foundation pit construction safety requirement is met, the influence of large foundation pit deformation on the surrounding environment is avoided, and the engineering cost can be reduced.

Description

technical field [0001] The invention relates to a structure and a construction method for controlling the deformation of a foundation pit, belonging to the technical field of industrial and civil construction engineering. Background technique [0002] With the development of the economy, in the construction of large and medium-sized cities, the construction land is becoming more and more scarce, and the cost of land is getting higher and higher, which has recently brought about the development of high-rise and super high-rise buildings, followed by the use of underground space and With the development, the characteristics of deep and large foundation pit engineering are also highlighted. In order to control the impact of foundation pit deformation on underground and above-ground structures, it is necessary to increase the anti-deformation capacity of the foundation pit enclosure system, which undoubtedly increases the construction cost. Contents of the invention [0003] ...
