摘要
针对公明水库-清林径水库连通工程竖井施工空间小,结构稳定要求高,周边基岩破碎等情况,拟采用地下连续墙的施工工艺,在对施工环境分析综合分析的基础上,进行施工合理布设,对地下连续墙施工中的导墙、泥浆护壁、成槽和浇筑环节进行控制,对施工中的技术质量关键问题进行技术控制,以确保基坑围护工程开挖施工安全稳固,为区间盾构隧道的稳定安全奠定基础.
Abstract
The connection project between Gongming Reservoir and Qinglinjing Reservoir has problems such as small vertical shaft construction space,high structural stability requirements,and broken surrounding bedrock.This paper intends to adopt the construction technology of underground continuous walls,and based on a comprehensive analysis of the construction environment,carry out reasonable construction layout.It controls the guide wall,mud protection wall,trenching,and pouring processes in the construction of underground continuous walls,and controls key technical quality issues during construction to ensure the safe and stable excavation and construction of foundation pit enclosure projects,laying the foundation for the stability and safety of interval shield tunnels.
