Hydropower station high-water-head vertical shaft pressure steel pipe drainage system and construction method
The hydropower station high-water-head vertical shaft pressure steel pipe drainage system comprises a pressure steel pipe arranged in a rock mass, lining concrete is arranged between the pressure steel pipe and the rock mass, and the pressure steel pipe is further sleeved with a water seepage and drainage ring pipe used for collecting pipe walls. The drainage ring pipe is arranged between the pressure steel pipe and the lining concrete, and the drainage ring pipe is communicated with a pipe wall drainage pipe used for discharging seepage water on the pipe wall. Auxiliary devices are additionally arranged on the outer wall of the pressure steel pipe and the concrete lining layer, so that the final purpose of drainage of the outer wall of the pressure steel pipe and the concrete lining layer of the vertical shaft is achieved; the problems that due to water seepage of the underground buried pipe, the power conveying pressure steel pipe runs unstably, and drainage is difficult when drained water enters a workshop are solved, the running safety and reliability of the power conveying pressure steel pipe during power generation are greatly improved, meanwhile, the running cost of a hydropower station is greatly saved, and the running efficiency of the later hydropower station power generation stage is improved.
本发明公开了一种水电站高水头竖井压力钢管排水系统及施工方法，包括设置在岩体中的压力钢管，所述压力钢管与岩体之间设置有衬砌混凝土，所述压力钢管外还套设有用于汇集管壁渗水排水环管，所述排水环管设置在压力钢管和衬砌混凝土之间，所述排水环管连通有用于排出管壁渗水的管壁排水管，本发明通过在压力钢管外壁及混凝土衬砌层加装辅助装置完成竖井压力钢管外壁及混凝土衬砌层排水的最终目的，解决了因地下埋管渗水造成动力输送压力钢管运行不稳定及排水进入厂房内部排水困难等难题，大大提高了发电期间动力输送压力钢管运行的安全可靠性，同时大大节约了水电站运行成本，提高了后期水电站发电阶段运行效率。
