Abstract

The embodiment of the invention discloses a construction method for excavating a deep foundation pit. The construction method includes the step of excavating soil, the step of erecting a supporting system and the step of setting a plurality of monitoring projects, wherein the step of erecting the supporting system is matched with the step of excavating the soil, and the step of excavating the soil and the step of erecting the supporting system are performed in a matched mode according to monitored data of the monitoring projects. According to the construction method, the step of excavating the soil and the step of erecting the supporting system are performed in a crossed mode, and the safety performance in the construction process is improved.

Description

technical field [0001] The invention relates to the technical field of engineering construction, in particular to a construction method for excavating deep foundation pits. Background technique [0002] With the continuous development of urban buildings, various types of engineering buildings, such as deep foundations of high-rise buildings, basements or underground structures, require deep foundation pit excavation. Earthwork excavation and support erection in foundation pit construction are the key processes that determine the success or failure of foundation pit construction, and are the main risk stages of deep foundation pit engineering. Earthwork excavation is an unloading process, which destroys and disturbs the strata, destroys the original equilibrium state of the soil structure, and causes changes in the stress field in the soil. The rebound of the subsoil and the inward movement of the enclosure and retaining structure. In order to effectively control this displ...
