Inclined supporting pile structure for foundation pit support and construction method thereof

Abstract

The invention relates to the field of foundation pit supports, in particular to an inclined supporting pile structure for a foundation pit support and a construction method of the structure. The inclined supporting pile structure for the foundation pit support comprises a fender post, a top beam, a foundation pit base plate, a building structure, an inclined supporting pile, a waterstop device and a soil improved structure, wherein the inclined supporting pile is implanted in primary soil below the foundation pit base plate in an inclined mode by a certain angle, the top end of the inclined supporting pile is fixedly connected with the top end of the fender post, and is embedded inside the top beam, and the whole structure is formed through the inclined supporting column and the top beam. The soil improved structure is fixed to the bottom end of the inclined supporting pile and the periphery of the bottom end of the inclined supporting pile, and the inclined supporting pile, the building structure and the foundation pit base plate penetrate through the waterstop device on the inclined supporting pile. According to the inclined supporting pile structure, the structural design and the construction method are reasonable, the construction period is greatly shortened, the construction cost are greatly reduced, barrier-free earth cutting and structural construction can be achieved, the structure is environmentally friendly and safe, and the potential safety hazards, generated by dismounting the support, of the suspended wall of the foundation pit support are thoroughly avoided.

Description

technical field [0001] The invention relates to the field of foundation pit enclosure, in particular to an oblique support pile structure for foundation pit enclosure and a construction method thereof. Background technique [0002] During the excavation of the foundation pit, the surrounding soil will inevitably be deformed, which will affect the surrounding buildings (structures) and underground pipelines. Seriously, it will endanger its normal use or safety. In order to avoid this situation, a support system will be added to stabilize the safety of the foundation pit in deep foundation design and pit construction. At present, there are three main forms: flat brace, diagonal brace 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, w...
