Reservoir head karst depression treatment method
The invention discloses a reservoir head karst depression treatment method, relates to the technical field of karst depression treatment, and solves the problems of proper disposal of karst depression flood drainage and cave excavation waste slag disposal when a reservoir is built in a karst region. According to the treatment method for the karst depression of the reservoir head, the karst depression is located on the upper portion of a mountain along the bank of the reservoir head, a water retaining dam is arranged at the position of the reservoir head, anti-seepage curtains connected with the water retaining dam are arranged on the two banks of the water retaining dam respectively, and the treatment method comprises the steps that grouting holes are built in the direction from the two sides of the water retaining dam to the mountain respectively, and the anti-seepage curtains are constructed in the grouting holes; when the grouting hole is built, a communicating hole communicating from the karst depression to the grouting hole is built on the side with the karst depression; filling the karst depression with hole excavation waste slag excavated by the grouting holes and the communicating holes to form permanent cultivated land; and the communicating hole and the grouting hole are communicated to form a flood discharge hole connected into the reservoir area from the karst depression.
本发明公开一种水库库首岩溶洼地处理方法，涉及岩溶洼地处理技术领域，解决了在喀斯特地区修建水库时妥善处置岩溶洼地排洪和洞挖弃渣处置的问题。本水库库首岩溶洼地处理方法，其中岩溶洼地处于水库库首沿岸山体上部，水库库首处设置有挡水大坝，挡水大坝两岸分别设置连接挡水大坝的防渗帷幕，包括：分别从挡水大坝两侧往山体方向修建灌浆洞，在灌浆洞内施工形成防渗帷幕；修建灌浆洞时，在具有岩溶洼地的一侧修建从岩溶洼地连通至灌浆洞的连通洞；灌浆洞及连通洞开挖的洞挖弃渣堆填在岩溶洼地内，形成永久耕地；连通洞和灌浆洞连通形成从岩溶洼地连接至水库库区内的排洪洞。
