Abstract

The invention relates to a foundation pit supporting structure and a foundation pit construction method, and relates to the technical field of foundation pit construction. The foundation pit supporting structure comprises a plurality of bidirectional telescopic rods and a connecting assembly used for connecting the two bidirectional telescopic rods which are arranged in a crossed mode. The two-way telescopic rod comprises a sleeve and two telescopic pipes, and the two telescopic pipes are located in inner cavities in the two ends of the sleeve respectively. Each telescopic pipe comprises a fixed pipe, at least one movable pipe and a one-way limiting assembly, the movable pipes are inserted into the fixed pipes and are in sliding connection with the fixed pipes, and the opposite ends of the fixed pipes of the two telescopic pipes are fixedly connected; the one-way limiting assembly is located between the fixed pipe and the movable pipe and used for controlling the movable pipe to slide out of the fixed pipe in a one-way mode. The foundation pit supporting structure has the effect of improving the applicability of the foundation pit supporting structure.

Description

technical field [0001] The present application relates to the technical field of foundation pit construction, and in particular, to a foundation pit support structure and a foundation pit construction method. Background technique [0002] The foundation pit is a soil pit excavated at the base design position according to the base elevation and the size of the base plane. The foundation pit is a temporary project whose purpose is to provide a space in which the foundation masonry work can be carried out according to the location specified by the design. Engineering foundation pits are mainly used for the construction of caps, bridge abutments and enlarged foundations, and are generally divided into two categories: unsupported and supported. [0003] In the related art, a foundation pit supporting structure is disclosed, which includes a plurality of steel pipe piles arranged in sequence along the circumference of the foundation pit. The steel pipe piles are vertically arrang...
