Construction of cut-off wall and vibro replacement gravel pile for capital junction of Peru San gawang Hydropower project
秘鲁圣加旺水电站工程首都枢纽防渗墙及振冲碎石桩工程
SAN Gavan Hydropower Station is located in the Puno region of southeast Peru. It is powered by low dam length diversion head and installed with 2 percussive hydro-generators with a total installed capacity of 209.3 MW. Hydropower station is mainly composed of the head hub, water diversion and power generation buildings. The impervious wall of the first hub and vibroflotation gravel pile project have many large pebbles, boulders and boulders in the stratum, and the geological conditions are complicated. The vibroflotation treatment is about 90,000 m, and the concrete impervious wall is nearly 10,000 m².
圣加旺水电站位于秘鲁东南部普诺大区，采用低坝长引水集中水头发电，安装2 台冲击式水轮发电机，总装机容量 209 .3MW。水电站主要由首部枢纽、引水发电建筑物等组成。首部枢纽防渗墙及振冲碎石桩工程地层大卵石、孤石、漂 石较多，地质条件复杂，振冲处理约9万m，混凝土防渗墙近1万m²。
