深圳抽水蓄能电站引水道首次充水试验研究

结合深圳抽水蓄能电站引水道首次充水试验过程,在施工支洞堵头、厂房排水廊道等部位布设量水堰,在高压岔管和地下厂房埋设渗压计、钢筋计进行充水过程监控,充水完成后,监测数据结果表明引水道总渗水量不大,说明引水道充水成功。引水道充水完成至今,引水道各主体工程状态正常,说明引水道设计合理,施工质量良好,结构安全可靠。

Experimental Study on the First Water Filling of the Headrace Tunnel of Shenzhen Pumped-storage Power Station

Combined with the first water filling test process of the headrace tunnel of Shenzhen Pumped-storage Power Station,the water measuring weirs are installed in the construction branch tunnel plugs,plant drainage corridors and other positions,and the piezometers and reinforcement stress meters are embedded in the high-pressure branch pipes and underground powerhouses for monitoring the test.After the water filling is completed,the monitoring data results show that the total seepage volume of the headrace tunnel is not large,indicating that the tunnel is successfully filled.Since the completion of water filling of the headrace tunnel,the main structures of the headrace tunnel are in normal condition,indicating that the design of the headrace tunnel is reasonable,the construction quality is good,and the structure is safe and reliable.
