Karst cave backfilling method based on karst cave and underground river environment tunnel construction
A karst cave backfilling method based on karst cave and underground river environment tunnel construction comprises the following steps that S1, an underground river is redirected, so that the underground river does not flow through a karst cave; S2, an upstream diversion intersection of the underground river is blocked; S3, a downstream part, located outside a karst cave area, of the undergroundriver is blocked; S4, the part, between two blocking points, of the underground river is backfilled; S5, a cave wall of the karst cave is protected, and a plurality of anchor cables are evenly constructed on the cave wall; S6, the karst cave is fully filled from bottom to top according to elevations on the basis of underground river backfilling, and the anchor cables are connected with a fully filled backfilling body; and S7, grouting is conducted in a gap between the backfilling body and the cave wall of the karst cave, and the gap is sealed. The karst cave backfilling method has the advantages of being stable, reliable, high in safety and capable of preventing a filler from settling.
一种基于溶洞暗河环境隧道施工的溶洞回填方法，包括以下步骤：S1：将暗河进行改道，使暗河不流经溶洞；S2：将暗河上游改道交汇处进行封堵；S3：将暗河位于溶洞区域外的下游进行封堵；S4：将两个封堵点之间的暗河进行回填；S5：对溶洞洞壁进行防护处理，并在洞壁上均匀施作多根锚索；S6：以暗河回填为基础由下至上分高程对溶洞进行满填，并使锚索与满填后的回填体连接；S7：在回填体与溶洞洞壁的间隙中进行灌浆，使间隙密封。具有稳定可靠、安全性高、能防止填体产生沉降的优点。
