Foundation pit supporting structure based on row piles and inner supports

Abstract

The invention discloses a foundation pit supporting structure based on row piles and inner supports, which comprises a plurality of pile bodies arranged on the side wall of a pit body, the pile bodies are vertically arranged, the lower ends of the pile bodies are inserted into soil, the pile bodies are used for supporting the side wall of the pit body, the multiple pile bodies are arranged side by side, the pile bodies located at the corners of the pit body are first pile bodies, and the pile bodies located at the corners of the pit body are second pile bodies; other pile bodies are second pile bodies, and clamping grooves are formed in the upper ends of the pile bodies; the rectangular frame can be clamped in the clamping grooves in the upper ends of the pile bodies, so that the multiple pile bodies form a stress whole; the clamping groove in the upper end of the first pile body is a first clamping groove, the clamping groove in the upper end of the second pile body is a second clamping groove, the first clamping groove is in an L shape, a rectangular frame is arranged, the rectangular frame is clamped in the clamping grooves in the upper ends of the pile bodies, then the multiple pile bodies form a stress whole, the pile bodies cannot incline towards the inner side, and the pile bodies cannot incline towards the inner side. And finally, the pile body can stably support the side wall of the pit body.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a foundation pit support structure based on row piles and internal supports. Background technique [0002] In building construction, it is necessary to build the foundation at the bottom, and the foundation pit is the stable point of the foundation. During the construction of the foundation pit, in order to prevent the outer layer of soil from falling into the foundation pit, a concrete layer will be built on the inner wall of the foundation pit, and row piles will be installed on the inner bottom of the foundation pit, so that the concrete layer can be supported by row piles. After the row of piles is installed, concrete will be poured on the top of the row of piles to form a crown beam, and the top of the concrete layer will be supported by the crown beam to prevent the top of the concrete layer from collapsing. [0003] However, in the existing found...

Problems solved by technology

[0003] However, in the existing foundation pit support structure, the installation stability of the row of piles is not enough. The specific row of piles is placed in the soil, and it is easy to be tilted or loosened by external force, which further affects the support stability of the side wall of the foundation pit. not enough
