马马崖一级水电站导流洞堵头混凝土快速施工技术

Rapid construction technique adopted for diversion tunnel plug concrete at Mamaya I Hydropower Station

根据马马崖水电站工程整体施工进度计划,导流洞下闸后,为确保洞内施工人员及设备安全,要求永久堵头安全、高效、快速施工完成。为此,结合工程的实际情况,设计了相应的导流洞封堵快速施工技术方案,实施后,安全、快速地完成了施工,导流洞封堵效果好。

According to the construction schedule of Mamaya I Hydropower Station,the permanent tunnel plug is required to be constructed safely and rapidly after the diversion tunnel is closed with gate.Combined with the actual conditions of the project,corresponding rapid construction scheme of tunnel plug was drafted and executed with good effects.
