摘要
在彭水水电站大坝导流洞永久堵头的封堵过程中,由于2号导流洞闸门下游渐变段出现大量漏水的现象,渗水量大约为1.3 m3/s,造成洞内积水,为此采取在永久堵头上下游设置混凝土临时堵头挡水,确保永久堵头干地施工。
During the construction of the permanent plug for the diversion tunnel of Pengshui Hydropower Project, leakage in a large quan-tity occurs at the transition section at the downstream of the Diversion Tunnel No.2 gate, resulting in water accumulated in the tunnel. The seepage flow is about 1.3 m3/s.Therefore, the temporary concrete plugs are proposed to build on both sides of the permanent plug to retaining the seepage so that the permanent plug can be constructed in dry condition.
