Abstract

The invention relates to a deep foundation pit supporting structure. The deep foundation pit supporting structure comprises a stress plate and a supporting rod arranged on one side of the stress plate; the side, away from the supporting rod, of the stress plate is connected with an insertion rod; the end face, close to the stress plate, of the insertion rod is provided with a fixed hole extending in the length direction of the insertion rod; the stress plate is provided with a grouting hole communicating with the fixed hole; a flow guide hole communicating with the outer wall of the insertion rod is formed in the hole wall of the fixed hole; an elastic piece used for opening and closing the flow guide hole is arranged on the insertion rod; one end of the elastic piece is a fixed end fixed to the side wall, away from the stress plate, of the flow guide hole; the other end of the elastic piece is a movable end extending towards the side, away from the insertion rod, of the flow guide hole; and the insertion rod is connected with an opening and closing assembly used for pushing the elastic piece to open the flow guide hole. The structure has the effect of improving the connecting strength of the stress plate and the side wall of a foundation pit.

Description

Technical field [0001] The present application relates to the technical field of foundation pit support, in particular, to a deep base pit support structure. Background technique [0002] Foundation pit support is to ensure the construction of underground structures and the environmental safety of the foundation pit, and the measures such as partition, reinforcement and protection of the side walls of the foundation pit and the surrounding environment, the common foundation pit support forms include pile support, Pile anchor support, etc. [0003] In the relevant technique, the announcement No. CN207597398U is disclosed in China Patent Publication Open a foundation pit support structure including the force plate and the oblique support rod. The upper upper portion of the force plate is fixedly provided with a lateral reinforcing column, and an infusion pile is provided in the foundation pit. The lower end of the oblique support rod is fixed to the top end of the infusion pile, an...
