1工程概述宝泉抽水蓄能电站位于河南省辉县市薄壁乡宝泉村附近,为引水式电站。装机容量1200MW,安装4台可逆式水泵水轮机。电站按两洞四机的布置方式,在厂房前90．0m处设置卜型岔管。岔管段总长20m,主管洞径6．5m,支管洞径4．5m,公切球直径5．5m,分岔角55°。岔管采用钢筋混凝土结构,衬砌厚度0．6m。高压岔管是电站引水系统的关键部分,该部分是否安全可靠直接关系到整个引水系统的结构性态。由于岔管部分几
1 Project Overview Baoquan pumped storage power station is located in Huixian City, Henan Province, near the village of Po-chuen, Baoquan Village, a diversion-type power station. Installed capacity of 1200MW, the installation of 4 reversible pump turbine. According to the arrangement of two holes and four machines, the power station shall set Bu-type bifurcation pipe at 90.0m in front of the plant. The length of the bifurcated pipe segment is 20m, the diameter of the competent pipe is 6.5m, the diameter of the branch pipe is 4.5m, the diameter of the public cut ball is 5.5m, and the branch angle is 55 °. Bifurcated reinforced concrete structure, the lining thickness of 0.6m. The high-pressure bifurcation pipe is a key part of the water diversion system of the power station. Whether the part is safe and reliable is directly related to the structural state of the entire water diversion system. Due to the bifurcation of some
