Anti-seepage drainage heat preservation structure suitable for pumped storage upper reservoir bank and construction method of anti-seepage drainage heat preservation structure
The invention discloses an anti-seepage drainage heat preservation structure suitable for a pumped storage upper reservoir bank and a construction method of the anti-seepage drainage heat preservation structure. The structure comprises a broken stone hardcore, a leveling cementing layer, a gravel-doped clay drainage pipe network layer, a fiber-doped asphalt concrete layer, a heat preservation layer and a mastic sealing layer which are sequentially arranged on the upstream side of the slope surface of a bank slope from inside to outside. And the leveling cementing layer is made of an asphalt mixture. The gravel-doped clay drainage pipe network layer is made of gravel-doped clay and a slope drainage pipe network buried in the gravel-doped clay, a water outlet in the lower end of the slope drainage pipe network is connected with a slope bottom drainage pipe, and the slope bottom drainage pipe penetrates through the backwater side of the bank slope. The anti-seepage drainage capacity of the reservoir bank on the pumped storage power station can be effectively improved, meanwhile, the flexible drainage layer is arranged below the asphalt concrete face, the structure arrangement is reasonable, operability is high, and the overall construction quality and the anti-seepage effect of the structure are guaranteed.
本发明公开了一种适用于抽水蓄能上水库库岸防渗排水保温结构及其施工方法，该结构包括从内到外依次设置在岸坡坡面迎水侧的碎石垫层、整平胶结层、掺砾黏土排水管网层、掺纤维沥青混凝土层、保温层和玛蹄脂封闭层。所述整平胶结层的材料为沥青混合料。所述掺砾黏土排水管网层的材料包括掺砾黏土以及埋设在掺砾黏土内的坡面排水管网，坡面排水管网下端的出水口与坡底排水管连接，坡底排水管贯穿岸坡的背水侧。本发明能够有效的提高抽水蓄能电站上水库库岸防渗排水能力，同时在沥青混凝土面板下设置柔性排水层，结构设置合理，可操作性大，保证了结构整体的施工质量和防渗效果。
