Anti-seepage reinforcing structure and construction method
The invention relates to an anti-seepage reinforcing structure and a construction method, an earth and rockfill dam is provided with an upstream side and a downstream side in the thickness direction, a geomembrane anti-seepage reinforcing structure comprises a geomembrane anti-seepage layer, a concrete tooth groove, a dam body drainage pipe and a drainage groove, the geomembrane anti-seepage layer comprises a geomembrane, and the geomembrane is laid on the upstream side of the earth and rockfill dam; the concrete tooth groove is located in the upstream side slope toe of the earth and rockfill dam, concrete is poured in the concrete tooth groove, and the geomembrane extends to one side of the concrete tooth groove and is connected with the concrete tooth groove in an anchoring mode. The dam body drainage pipe extends in the thickness direction of the earth and rockfill dam and penetrates through the upstream side and the downstream side of the earth and rockfill dam. The drainage groove extends along the dam face of the earth and rockfill dam and communicates with a dam body drainage pipe. In addition, the geomembrane impermeable layer further comprises a three-dimensional geotechnical drainage net and a cushion layer, and the cushion layer, the three-dimensional geotechnical drainage net and the geomembrane are sequentially laid on the upstream side of the earth and rockfill dam. The geomembrane anti-seepage reinforcing structure can reinforce an anti-seepage structure and a drainage structure of an earth and rockfill dam.
本申请涉及一种防渗加固结构及施工方法，土石坝在厚度方向上具有上游侧和下游侧，土工膜防渗加固结构包括土工膜防渗层、混凝土齿槽、坝体排水管和排水槽，土工膜防渗层包括土工膜，土工膜铺设于土石坝的上游侧；混凝土齿槽位于土石坝的上游侧坡脚，混凝土齿槽内浇筑有混凝土，土工膜延伸至混凝土齿槽的一侧并与混凝土齿槽锚固连接；坝体排水管沿土石坝的厚度方向延伸并贯穿土石坝的上游侧和下游侧；排水槽沿土石坝的坝面延伸，排水槽与坝体排水管连通；此外，土工膜防渗层还包括三维土工排水网和垫层，垫层、三维土工排水网和土工膜依次铺设于土石坝的上游侧；该土工膜防渗加固结构能够强化土石坝的防渗结构及排水结构。
