摘要
本文主要阐述了锦屏二级水电站引水隧洞成功封堵1 m3/s以上高压大流量涌水的思路及方案,介绍了盖重混凝土浇筑、沉箱强制引排及针对出水大小添加特材比例控制等重大施工技术突破。
The concept and scheme for successfully sealing high pressure and large flow groundwater surge of 1 m3/s occurred in the diversion tunnel of Jinping II Hydropower Station are mainly expatiated herein, and then the important technical breakthroughs such as placement of cover-weight concrete, forced drainage with caisson, proportion control on the special additive materials for sealing groundwater surges with various inflows, etc. are introduced as well.
