1 Project Overview Xiaolangdi Hydro Project supporting project - Xixiayuan anti-regulation reservoir is located downstream of Xiaolangdi Project 16km. Its development tasks to counter-adjustment-based, combined with power generation, taking into account irrigation, water supply and other comprehensive utilization. The permanent structures of the project are composed of concrete dams (including flood gates, riverbed power stations, drainage sluices), earth-rock dams, irrigation diversions, and Wangzhuang diversion gates. Among them, the right bank earth-rock dam is 857.7m long and the left bank earth-rock dam is 1725.5m long. 2 Construction Technology Concrete cutoff wall construction process flow chart shown in Figure 1.
