Pumped storage upper reservoir dry-wet cycle lower thermal insulation anti-seepage reservoir bank structure and construction method thereof
The invention discloses a pumped storage upper reservoir dry-wet cycle lower heat preservation anti-seepage reservoir bank structure and a construction method thereof. The structure is sequentially provided with a broken stone hardcore, a leveling cementing layer, an asphalt stabilized broken stone drainage layer, a polyester grid, a fiber-doped asphalt concrete layer, a heat preservation layer and a mastic sealing layer from inside to outside on the upstream side of the slope surface of a bank slope. The leveling cementing layer is made of an asphalt concrete mixture, and the porosity of the leveling cementing layer is 10%-15%. The asphalt stabilized macadam drainage layer is made of an asphalt macadam mixture, and the porosity of the asphalt stabilized macadam drainage layer is 15%-25%. The fiber-doped concrete is adopted, the defects of a traditional asphalt concrete panel anti-seepage technology are overcome, the heat preservation layer is additionally arranged on the basis, and the problem that due to frequent water level fluctuation of an upper reservoir, the panel is prone to cracking due to dryness, wetness and temperature changes is effectively solved.
本发明公开了抽水蓄能上水库干湿循环下保温防渗库岸结构及其施工方法，该结构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、沥青稳定碎石排水层、聚酯网格、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凝土混合料，整平胶结层的孔隙率为10％～15％。所述沥青稳定碎石排水层的材料为沥青碎石混合料，沥青稳定碎石排水层的孔隙率为15％～25％。本发明采用了掺纤维混凝土，改善了传统沥青混凝土面板防渗技术的缺陷，在此基础上加上保温层，有效解决了上水库的水位涨落频繁带来的干湿、温度变化面板易产生裂缝的问题。
