摘要
导流隧洞的封堵施工是水利枢纽工程下闸蓄水后需立即实施的最后一个关键施工项目,其封堵的成功与否及效果好坏直接关系到水电站坝前库区的蓄水速度及厂房机组的发电出力大小。长潭河水利水电枢纽工程导流隧洞永久混凝土堵头在洞内渗水严重、岩体较差等特殊地质条件下成功实施封堵并达到了预期效果,取得了良好的经济效益和社会效益。
Plugging Technology for diversion tunnel is the last key construction projects need to be immediately implemented after water storage in the water hydro-junction project.The plugging result is directly related to the power station dam reservoir water storage rate and plant power output size.In Changtan River hydro-junction project,the diversion tunnel is plugged successfully under the special geological conditions of bad rock strength and severe water leakage in the tunnel which gain good social benefit and economic benefit.
