Karst cave section anchor cable construction method based on karst cave underground river environment tunnel construction
The invention discloses a karst cave section anchor cable construction method based on karst cave underground river environment tunnel construction. The method comprises the following steps that S1, atunnel section A is subjected to excavating until the tunnel section A communicates with a karst cave; S2, an underground river is diverted to enable the underground river to not flow through the karst cave; S3, the karst cave is subjected to backfilling, until backfilling is conducted on a tunnel foundation surface; S4, the cave wall of the karst cave is protected; S5, anchor hole construction is conducted on the cave wall, and an expansion bolt is driven into the rock surface on the periphery of an anchor hole; S6, a pulley is arranged on the rock surface on the side edge of the anchor hole, and a winch is used for pushing an anchor cable into the anchor hole; S7, after the anchor cable is pushed in place, the anchor cable is fixed to the expansion bolt through an iron wire, and the pulley and the winch are detached; S8, grouting is conducted on the anchor hole to enable the anchor cable is fixed to the rock surface of the cave wall; and S9, the karst cave is subjected to full filling to enable the anchor cable is fixedly connected with a backfilled body subjected to full filling. The method has the advantages of being stable and reliable, high in safety and capable of preventing sedimentation.
一种基于溶洞暗河环境隧道施工的溶洞段锚索施工方法，包括以下步骤：S1：将隧道A段开挖至连通溶洞；S2：对暗河进行改道，使暗河不流经溶洞；S3：对溶洞进行回填，直至回填至隧道基础面；S4：对溶洞洞壁进行防护处理；S5：对洞壁进行锚孔施工，在锚孔周边的岩面上打入膨胀螺栓；S6：在锚孔侧边的岩面上安装滑轮，利用卷扬机将锚索向锚孔中推送；S7：在锚索推送就位后，用铁丝将锚索固定在膨胀螺栓上，卸除滑轮和卷扬机；S8：对锚孔进行灌浆使锚索与洞壁岩面固定；S9：对溶洞进行满填，使锚索与满填后的回填体形成固定连接。具有稳定可靠、安全性高、能防止沉降的优点。
