A foundation pit support structure based on multi-miniature piles and its construction method

Abstract

The invention discloses a foundation pit support structure based on multi-miniature piles, which includes a border protection mechanism, a pit wall support mechanism and a drainage mechanism. The border protection mechanism includes a base, and the upper surface of the base is fixedly connected with The support column, the front of the base is fixedly connected with an electric control box, the pit wall support mechanism includes a crown beam, and the lower surface of the crown beam is fixedly connected with micro piles; the present invention also proposes a multi-miniature pile-based The construction method for the support structure of the foundation pit includes the following steps: S1, using the support column to fix the protective net, and using the electric control box and the light bulb to provide lighting for people at night. The foundation pit support structure based on multi-micro piles can provide lighting at night by setting electric control boxes and light bulbs, protect light bulbs by setting light boxes, prevent water and soil landslides by setting baffles, and prevent landslides by setting micro piles, The pressure-dividing horizontal plate and the pressure-dividing vertical plate can achieve a safer and more stable effect of the foundation pit support structure based on the multi-miniature piles.

Description

technical field [0001] The invention relates to the technical field of foundation pit support, in particular to a foundation pit support structure based on multiple miniature piles and a construction method thereof. Background technique [0002] Foundation pit support is to ensure the safety of the underground structure construction and the surrounding environment of the foundation pit. The support, reinforcement and protection measures are adopted for the side wall of the foundation pit and the surrounding environment. The common support forms include row pile support and continuous wall. Support, cement retaining wall, soil nail wall, original soil grading, etc. [0003] Micro-piles refer to cast-in-situ piles with a pile diameter less than four meters and an aspect ratio greater than 30, which adopt drilling, strong reinforcement and pressure grouting construction techniques. The existing micro-pile foundation pit support generally has low stability, and there are Securi...
