裕溪船闸复线工程闸室施工技术

Construction technology of lock chamber in the twin-line project of Yuxi lock

深软土基上闸室工程施工,不仅影响工程的工期、造价,而且还直接影响到工程质量与后期维护。结合裕溪船闸复线工程深软地基闸室施工经验,对闸室基础处理、闸室墙底节模板及支护、垂直度控制等施工过程进行详细阐述。指出合理组织、严格执行以及及时监测、科学分析与决策是复杂地基闸室施工前提条件。

The construction of the lock chamber on the deep soft ground can affect not only the project duration and cost,but also the project quality and later maintenance.This paper expounds in detail the soft ground treatment of the lock chamber,the bottom form of chamber wall and form brace,and the controlling of perpendicularity,etc.It reveals the preconditions of complicated foundation in the construction of the lock chamber： proper organization,strict execution,timely monitoring and survey,as well as scientific analysis and decision.
