Fengshun County, Guangdong Province, Hanjiang Dongshan Water Conservancy Project is based on power generation, taking into account the shipping of a comprehensive water control project. Above the dam site, the catchment area is 27,500 km 2, the normal designed water reservoir is 25.5m, the check flood level is 32.44m, and the total storage capacity is 1.16 × 108m 3. Engineering grade I and other large (1) type of project, the main building is 2, the secondary building is 3. The project is located on the Hanjiang section of Dongshan Village, Liuhuang Town, Fengshun County with a total hub width of 624.29m. The hub is composed of a right bank powerhouse, a middle 19-hole barrage, a left bank lock, left bank and right bank connecting earth dam and substation. This paper introduces the layout and construction control of anti-seepage wall of high-jetting seepage prevention wall in the first phase of Dongshan Project, and proposes relevant problems for reference and improvement of the second-phase project to ensure the smooth implementation of the project.
