Underground river diversion method based on karst cave underground river environment tunnel construction
The invention discloses an underground river diversion method based on karst cave underground river environment tunnel construction. The method comprises the following steps that S1, excavation construction is conducted outside a karst cave area to obtain a drainage tunnel communicating with the upstream portion of an underground river; S2, excavation construction is conducted outside the karst cave area to obtain a blocking channel communicating with the upstream portion of the underground river, and the intersection point of the blocking channel and the underground river is located at the downstream portion of the intersection point of the drainage tunnel and the underground river; S3, the underground river is blocked through the blocking channel, so that river water is diverted to flowout from the drainage tunnel; S4, excavation construction is conducted outside the karst cave area to obtain a backfilling channel communicating with the downstream portion of the underground river; and S5, the downstream portion of the underground river is subjected to backfilling through the backfilling channel. The method has the advantages of being convenient in operation, stable and reliable,high in safety and capable of preventing the settlement of a backfilling body.
一种基于溶洞暗河环境隧道施工的暗河改道方法，包括以下步骤：S1：在溶洞区域外开挖施工一条与暗河上游连通的泄水洞；S2：在溶洞区域外开挖施工一条与暗河上游连通的封堵通道，封堵通道与暗河的交汇点位于泄水洞与暗河交汇点的下游；S3：通过封堵通道对暗河进行封堵，使河水改道从泄水洞流出；S4：在溶洞区域外开挖施工一条与暗河下游连通的回填通道；S5：通过回填通道将暗河下游进行回填。具有操作方便、稳定可靠、安全性高、能防止填体产生沉降的优点。
