Abstract

The invention discloses a deep foundation pit supporting structure, which relates to the technical field of foundation pit excavation engineering. The anchor rod and the fixed anchor rod are connected, and the two support bases are hinged on both sides of the support rod respectively, and the two support bases are respectively fixed and installed on the side plate and the bottom plate, and mounting holes are opened on the side plate and the bottom plate. Both the anchor rod and the second plug-in anchor rod include a hollow body, a threaded rod, a drive disk, and a plurality of plug-in boards slidably connected to the circumferential side wall of the drive disk. There are one-to-one corresponding chutes, the plug-in boards are respectively slidably plugged into the chutes through the drive disk, and the first plug-in anchor rod and the second plug-in anchor rod are respectively installed on the side plate and the bottom plate; through the above structure Supporting deep foundation pit has the purpose of improving its construction quality, firmness and stability of supporting structure.

Description

technical field [0001] The invention relates to the technical field of foundation pit excavation engineering, more specifically, it relates to a deep foundation pit support structure. Background technique [0002] The foundation pit will inevitably cause deformation of the surrounding soil during the excavation process, which will affect the surrounding buildings and underground pipelines, and seriously endanger its normal use or safety; in order to avoid this situation, it will increase Support system to stabilize the safety of foundation pit, there are three main forms: flat support, diagonal support and reverse anchoring technology. [0003] Flat braces are currently widely used in deep foundation pits, but flat braces take up a lot of space in the pit, and the construction period is long, which is not conducive to excavation operations. There are great safety hazards in later demolition, which not only increases the cost of the project, but also is not conducive to envir...
