Abstract

The invention discloses a foundation pit supporting structure based on multiple mini piles. The structure comprises an edge protection mechanism, a pit wall supporting structure and a drainage mechanism. The edge protection mechanism comprises a base, the upper surface of the base is fixedly connected with supporting columns, and the front face of the base is fixedly connected with an electric control box. The pit wall supporting mechanism comprises a top beam, and the lower surface of the top beam is fixedly connected with the mini piles. The invention further provides a construction method of the foundation pit supporting structure based on the multiple mini piles. The construction method includes the following steps that S1, a protection net is fixed through the supporting columns, andillumination is provided for staff at night through the electric control box and a lamp bulb. According to the foundation pit supporting structure based on the multiple mini piles, through the arrangement of the electric control box and the lamp bulb, illumination can be provided at night; through the arrangement of a lamp box, the lamp bulb can be protected; through the arrangement of baffles, water and soil landslide can be blocked; and through the arrangement of the mini piles, pressure sharing cross plates and pressure sharing vertical plates, the foundation pit supporting structure basedon the multiple mini piles has the effects of being safer and more stable.

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...
