观音湖隧道快速施工技术研究

Research on Rapid Construction Technology of Guanyin Lake Tunnel

在涪江水系同步实施半闭半流和项目节点工期十分紧张的情况下,对遂宁观音湖隧道工程进行了重难点分析,介绍了如何科学组织、快速有序地选择施工方案,以投入多倍于常规的策略,重点突出"抢、快、严、优",实施湖中围堰、深基坑开挖与支护、模板与支架设计、清水混凝土浇筑、综合防水等关键技术,为类似工程提供借鉴。

Considering synchronous implementation of half-closing and half-flowing for the Fujiang River water system and highly tense schedule,the paper analyzed the emphasis and difficulties of Guanyin Lake Tunnel engineering in Suining,and introduced how to select the construction plan scientifically,rapidly and orderly,so as to put into times strategies of the conventional to highlight the characteristics of ＂rush,fast,strict and excellent＂. By implementing the key technologies such as cofferdam in lake,excavation and supporting of deep foundation pit,template and support design,concrete pouring and composite waterproof,it could provide reference for similar projects.
