Abstract

The invention discloses a foundation pit structure comprising a pit (1) formed by down digging, a pit peripheral engineering pile (2) arranged on one side of the pit (1) and a hard shell layer (4). Residual slurry overflowing during installation of the pit peripheral engineering pile (2) is solidified on the pit bottom of the pit (1) to form the hard shell layer (4), and the hard shell layer (4) is used for allowing excavation equipment to enter for operation. The foundation pit structure has the advantages that the residual slurry in the foundation pit construction process is used, the hard shell layer is formed at the pit bottom of the pit, the operation of laying gravels on the foundation pit bottom is eliminated, the residual slurry is utilized, and the on-site construction environmentis tidied.

Description

technical field [0001] The invention relates to a foundation pit structure and a construction method thereof. Background technique [0002] In the existing foundation pit, first divide the foundation pit area, then implement the engineering pile driving operation, and then drive into the excavation equipment to excavate the soil in the foundation pit area until the foundation pit that meets the elevation depth is reached. When the soil in the foundation pit area is relatively soft, the excavation equipment excavating the foundation pit area will crush or crook the engineering piles driven into the soil when excavating the soil. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a foundation pit structure, which overcomes the shortcomings of the background technology and cleans up the construction environment on site. [0004] In order to solve the above technical problems, the technical solution provided by the pre...
