Suspension Protection System and Construction Method of Water Supply Pipe Crossing Foundation Pit

Abstract

The invention relates to a suspension and protection system for a water supply pipe crossing a foundation pit and a construction method. The system is characterized by comprising a water supply pipe area foundation pit excavation auxiliary sizing device; a pile-beam integrated suspension supporting beam placing system; a unit assembly type suspension and protection system for the water supply pipecrossing the foundation pit; a rigid cast-in-situ concrete base and light roof covering backfill system for the water supply pipe crossing the foundation pit. The invention belongs to the field of underground engineering, effectively protects the integrity of a water supply pipe crossing the foundation pit, improves the construction safety, solves the integral stability problem of the suspensionsupporting structure consisting of a supporting pile and a reinforced concrete lintel, and obviously improves the construction efficiency, the construction process is simple and feasible. And good technical and economic benefits can be obtained when the system is applied to practical projects.

Description

technical field [0001] The invention relates to the technical field of underground water supply pipe protection engineering, in particular to a suspension protection system and a construction method for a water supply pipe crossing a foundation pit. Background technique [0002] With the continuous improvement of my country's comprehensive national strength, the basic transportation facilities of various cities in our country are changing with each passing day, especially the subway project is constantly under construction. The subway project is basically located under the main roads of the city, and it is easy to interact with the existing municipal pipelines, especially in the process of open excavation foundation pit construction. If the necessary measures are not taken for the pipeline before construction, there will be a greater risk of damage during the construction process, which will affect the progress of the construction in the slightest, and cause communication in...

AI Technical Summary

Problems solved by technology

In the existing construction, the excavation process near the pipeline is likely to cause damage to the pipeline and the construction efficiency is not high. The integrity and stability of the connection between the lintel and the support pile are poor, and the water supply pipe is likely to be damaged during the backfill process of the water supply pipe across the foundation pit, etc. question
