浅论导流洞龙抬头段封堵施工技术

摘要

导流隧洞封堵水库下闸蓄水是水利枢纽工程建设的一个重要里程碑,而导流洞封堵施工又是实现这一里程碑的关键.着重对吉林省老龙口水利枢纽工程导流洞龙抬头、封堵闸门槽及门顶引水洞底板闸门孔口封堵的施工工艺进行探讨,对类似工程提供一定的借鉴.%Diversion tunnel plugging reservoir impoundment is an important milestone in the construction of water conservancy project, and diversion tunnel plugging construction is key to achieving this milestone.In this paper, Laolongkou Water Conservancy Project of Jilin Province, especially the diversion tunnel in the rise of the dragon, plugging gate slot and portal roof construction technology of diversion bottom hole gate hole plugging were introduced in details, which provide certain reference for similar projects.
