A construction method of deep foundation pit and its intelligent detection system

Abstract

The invention provides a construction method of a deep foundation pit and an intelligent detection system thereof, comprising: a first foundation pit area, a second foundation pit area and a third foundation pit area, the first foundation pit area and the second foundation pit area A first construction platform is dug at the joint position of the second foundation pit area and a second construction platform is dug at the joint position of the second foundation pit area and the third foundation pit area. The centers of the inner cavities of the three foundation pit areas are all vertically poured with support piles. In the present invention, through the cooperation of the first foundation pit excavation, the first foundation pit support protection, the second foundation pit excavation, the second foundation pit support protection and the third foundation pit excavation, the overall deep foundation pit can be cyclically progressive At the same time, it can effectively support and protect the slopes of the first foundation pit area, the second foundation pit area and the third foundation pit area, preventing the first foundation pit area, the second foundation pit area and the third foundation pit area from In the process of excavation, landslides and blockages occur, which improves the overall excavation safety performance of deep foundation pits.

Description

technical field [0001] The invention relates to the field of deep foundation pit construction, in particular to a construction method of a deep foundation pit and an intelligent detection system thereof. Background technique [0002] Deep foundation pit refers to a project whose excavation depth is more than 5 meters (including 5 meters), or the depth is less than 5 meters, but the geological conditions, surrounding environment and underground pipelines are particularly complicated. Using the central island excavation method and the basin excavation method, in the process of excavating the foundation pit, the supporting slope protection effect is poor, which will easily lead to landslides on the slope of the foundation pit, which will easily cause accidental burial of equipment and personnel. It greatly affects the overall excavation progress of the foundation pit, and during the excavation process of the foundation pit, real-time sensing monitoring of the depth data and tem...
