Whole reservoir basin surface anti-seepage reservoir bottom gallery structure and construction method thereof
The invention provides a whole reservoir basin surface anti-seepage reservoir bottom gallery structure which comprises an anti-seepage panel arranged on a reservoir basin bank and a geomembrane covering the reservoir bottom, and meanwhile a drainage gallery on the periphery of the reservoir bottom is communicated with a traffic gallery communicated with the outside of the reservoir. A diversion channel in the construction period of the reservoir basin is formed through the drainage corridor and the traffic corridor; the traffic corridor is provided with a corridor extension section in a protruding mode in the direction towards the middle of the reservoir basin, and the corridor extension section is communicated with the drainage corridor and the traffic corridor through flow guide channels. A permanent channel is formed by arranging the gallery extension section with priority drainage and reserving the flow guide notch in the top of the gallery extension section, the flow guide problem in the construction period can be solved by adopting a prefabricated cover plate for blocking, meanwhile, overhaul and maintenance in the operation period can be achieved through the flow guide notch, and the construction period is shortened. And the function of the drainage gallery is further improved.
本发明提供了一种全库盆表面防渗库底廊道结构，包括设置在库盆库岸的防渗面板，以及覆盖在库底的土工膜，同时库底周边的排水廊道和与连通库外的交通廊道之间相互连通，通过所述排水廊道和所述交通廊道形成库盆施工期的导流通道；所述交通廊道在其朝库盆中间部分方向突出设置廊道延伸段，且所述廊道延伸段与所述排水廊道以及所述交通廊道之间通过导流道连通。本发明通过设置具有优先级排水的廊道延伸段，在廊道延伸段顶部预留导流缺口，来形成一个永久性通道，并可采用预制盖板进行封堵的方式，来解决施工期的导流问题，同时也可通过导流缺口实现运行期检修维护，进一步提高了排水廊道的功能。
