Drainage tunnel treatment method for building small and medium-sized reservoirs in karst depression areas
The invention discloses a drainage tunnel treatment method for building small and medium-sized reservoirs in karst depression areas. The drainage tunnel treatment method comprises the following steps that a drainage tower is arranged by using a natural drainage tunnel in a natural reservoir basin, a trash rack, a gate and a channel connected with the natural drainage tunnel are arranged in the drainage tower, and a reinforced concrete locking opening is built in the natural drainage tunnel; and the drainage of flood and the plugging of the drainage tunnel during water storage of the reservoir are realized. According to the drainage tunnel treatment method for building the small and medium-sized reservoirs in the karst depression areas, the drainage tower is used for blocking the drainage tunnel when the reservoir normally stores water, the natural drainage tunnel is used as a flood discharge channel in the flood season, flood discharge is achieved by opening a gate structure in the drainage tower, and for reservoir construction with the reservoir basin condition of the natural drainage tunnel in a karst area, the blocking effect is good. Original hydrogeological conditions are damaged as little as possible, and the drainage tunnel treatment method for building the small and medium-sized reservoirs in the karst depression areas is eco-friendly to the tail end area of an original underground river system.
本发明公开了一种在岩溶洼地地区修建中小型水库的落水洞处理方法，利用天然库盆中的天然落水洞设置泄水塔，泄水塔内部设置拦污栅、闸门、及与天然落水洞衔接的通道，天然落水洞修筑钢筋混凝土锁口，实现洪水宣泄和水库蓄水时落水洞的封堵。利用泄水塔，实现水库正常蓄水时对落水洞进行封堵，汛期利用天然落水洞作为泄洪通道通过开启泄水塔中的闸门结构实现洪水下泄，对岩溶地区具有天然落水洞的库盆条件的水库施工来说，封堵效果好，尽可能少的破坏原有水文地质条件，对原暗河系统末端地区生态友好。
