Forebay anti-seepage drainage structure of vertical shaft type water inlet or water outlet and construction method thereof
The invention provides a forebay anti-seepage drainage structure of a vertical shaft type water inlet or a water outlet, a surface anti-seepage structure is arranged on a reservoir bank, a reservoir bottom and a forebay of a reservoir, the reservoir bottom of the forebay is provided with a vertical shaft type water inlet/outlet structure, and a drainage gallery is arranged on the lower portion of the surface anti-seepage structure. The drainage galleries are provided with first drainage galleries communicated with the outside of the reservoir basin at the periphery of the reservoir bottom, the periphery of the top and the periphery of the bottom of the forebay are respectively provided with second drainage galleries and third drainage galleries, and the second drainage galleries are communicated with the first drainage galleries in the same structural layer; and a communicating gallery is arranged on the forebay bank slope section between the third drainage gallery and the second drainage gallery. The drainage galleries on the periphery of the top of the forebay are communicated with the channel for draining the reservoir bottom seepage water to the foundation pit, so that the drainage pressure in the forebay is reduced, and the leakage monitoring accuracy of the anti-seepage structure is also improved.
本发明提供了竖井式进水口或出水口的前池防渗排水结构，在水库的库岸、库底和前池上共同设置表面防渗结构，所述前池的库底设置有竖井式进/出水口结构，所述表面防渗结构的下部设置排水廊道，所述排水廊道在库底的四周设置连通库盆外部的第一排水廊道，所述前池的顶部周边和底部四周分别设置第二排水廊道和第三排水廊道，所述第二排水廊道与同一结构层内的第一排水廊道相连通，所述第三排水廊道与第二排水廊道之间的前池岸坡段设置连通廊道。本发明通过前池顶部四周的排水廊道接通库底渗水向基坑排泄的通道，不仅降低前池内排水压力，也提高了防渗结构渗漏监测的准确性。
