摘要
根据设计要求,冶勒水电站工程右坝体深厚覆盖层防渗墙处理深度需达220m。目前,国内外施工工艺无法达到该深度,设计将防渗墙分为上、下两段,下段防渗墙在廊道内施工,在施工中采用了最先进的成墙设备--双轮铣及改型的低桅杆冲击反循环钻机,取得了良好效果。
Base on the design requirements, the cut-off system in the right bank area of Yele hydropower station has to reach 220 m deep. This depth cannot be reached by any reliable construction technologies worldwide presently. Cut-off system has been divided into upper and lower sections. Regarding the lower section, the cut-off wall executed in a tunnel, the latest and advance equipment Bauer Trench Cutter and modified low head percussion drilling rig have been used in this project successfully.
