市政结构顶管工程沉井结构设计分析

Design Analysis of Caisson Structure for Municipal Structure Pipe Jacking Project

在市政结构顶管工程中,沉井结构的设计需要根据实际情况进行,在设计中,为了保证设计符合要求,应对沉井的特点以及工程要求合理设计,控制好各项参数,加强沉井结构的设计效果。本文对市政顶管工程沉井结构方案进行了阐述,结合某市政结构顶管工程分析市政结构顶管工程沉井结构设计内容,包括沉井井壁厚度设计,标高设计,平面尺寸设计,顶力计算,环向计算,竖向抗拉计算等。通过对顶管工程沉井结构的合理设计,为顶管井的设计提供更好的条件,加强工程的建设效果,使市政工程的整体质量得到提升。

In the municipal structure pipe jacking project,the design of the caisson structure needs to be carried out according to the actual situation.In the design,in order to ensure that the design meets the requirements,the characteristics of the caisson and the engineering requirements are reasonably designed,and various parameters are controlled to make the caisson structure The design effect is enhanced.This article describes the caisson structure plan of municipal pipe jacking project,and analyzes the caisson structure design content of municipal structure pipe jacking project in combination with a municipal structure pipe jacking project,including the design of caisson wall thickness,elevation design,plane size design,jacking Force calculation,hoop calculation,vertical tensile calculation.The rational design of the caisson structure of the pipe jacking project provides better conditions for the design of the pipe jacking well,strengthens the construction effect of the project,and improves the overall quality of the municipal engineering.
