摘要
针对岩滩水电站扩建工程5号、6号机组尾水检修闸门室施工因尾水隧洞交面时间滞后,闸门室超高超深、空间窄小、地质条件较差而增加施工内容和施工难度等问题,笔者从闸门室开挖支护、混凝土施工、闸门安装等方面阐述了施工组织设计优化,通过改变闸室开挖方案和混凝土施工方式,精心策划,科学安排,实现了优质、高效施工,且按合同工期完工。
In view of the problems of construction content and construction difficulty caused by the lag of tailrace tunnel intersection time,ultra-high and ultra-deep gate chamber,narrow space and poor geological conditions in the construction of tailrace bulkhead gate chamber of No.5 and No.6 units of Yantan Hydropower Station extension project,the author expounds the construction organization design optimization from the aspects of gate chamber excavation support,concrete construction and gate installation.By changing the gate chamber excavation scheme and concrete construction method,careful planning and scientific arrangement,high-quality and efficient construction is realized,and the construction is completed according to the contract period.
