市政工程基坑中竖井支护工艺运用研究

Study on the Application of Shaft Support Technology in Municipal Engineering Foundation Pit

随着市政工程复杂性的增加,基坑中竖井支护工艺的选择及其施工管理变得尤为关键。本文深入分析了竖井支护工艺的选择原则、常见技术及其技术创新,包括钢支撑、混凝土喷射和锚杆支护等,并讨论了各技术的适用条件和优缺点。在此基础上,本文探讨了支护工艺施工管理的技术要点和支护效果的评估方法,希望为市政工程基坑竖井支护提供一定的参考。

With the increase of the complexity of municipal engineering,the selection of the shaft support technology and its construction management in the foundation pit have become particularly critical.This paper deeply analyzes the selection principles,common technologies and technical innovations of the shaft support process,including steel support,concrete injection and bolt support,and discusses the applicable conditions and advantages and disadvantages of each technology.On this basis,this paper discusses the technical points of supporting process construction management and the evaluation method of supporting effect,hoping to provide some reference for the foundation pit shaft support of municipal engineering.
