Reservoir deep foundation reservoir bottom composite membrane anti-seepage structure and construction technology
The invention discloses a reservoir deep foundation reservoir bottom composite membrane anti-seepage structure and a construction technology, and belongs to the technical field of reservoir construction. A reservoir deep foundation reservoir bottom composite membrane anti-seepage structure comprises an intercepting and sewering ditch, a drainage system used for drainage is arranged in the intercepting and sewering ditch, the reservoir deep foundation reservoir bottom composite membrane anti-seepage structure further comprises a blind ditch drainage system, the blind ditch drainage system is communicated with the intercepting and sewering ditch, a geomembrane is laid on the end face of the top of the blind ditch drainage system, and a geotechnical blind pipe is arranged in the blind ditch drainage system; the blind ditch drainage system communicated with the cut-off ditch is formed in the reservoir bottom, the geotechnical blind pipe is laid in the blind ditch drainage system, water or gas permeating underground can be discharged into the cut-off ditch through the geotechnical blind pipe, the drainage efficiency and the safety of the geomembrane are improved, the risk that the geomembrane is floated and broken due to gas expansion is avoided, and the safety of the geomembrane is improved. Therefore, the anti-seepage effect of the reservoir can be obviously improved.
本发明公开了一种水库深基库底复合膜防渗结构及施工工艺，属于水库施工技术领域。一种水库深基库底复合膜防渗结构，包括截渗沟，所述截渗沟内设置有用于排水的排水系统，还包括盲沟排水系统，所述盲沟排水系统与截渗沟相连通，所述盲沟排水系统顶部端面铺设有土工膜，且所述盲沟排水系统内设置有土工盲管；本发明通过在库底开设与截渗沟相连通的盲沟排水系统，在盲沟排水系统内铺设土工盲管，可以将地下渗入的水或气经过土工盲管排放到截渗沟内，提高排水效率与土工膜的安全性，避免土工膜因气胀而浮托、胀破的风险，从而可以显著提高水库的防渗效果。
