Construction method of tunnel main cave side area based on karst cave underground river environment tunnel construction
The invention discloses a construction method of a tunnel main cave side area based on karst cave underground river environment tunnel construction. The method comprises the steps that S1, a tunnel section A is excavated to communicate with a karst cave; S2, the underground river is subjected to course change; S3, the karst cave is backfilled; S4, the cave wall of the karst cave is protected, anda plurality of anchor cables are evenly constructed on the cave wall; S5, the karst cave is fully filled, and the anchor cables are connected with a fully filled backfilling body; S6, the backfillingbody is excavated to form a tunnel section B; S7, measuring and setting out are performed on the left side and the right side of the tunnel section B; S8, mechanical excavation is performed on the left side and the right side of the tunnel section B; S9, base plane treatment is performed on the left side and the right side of the tunnel section B; S10, primary concrete spraying is performed on theleft side and the right side of the tunnel section B; S11, anchor cable and anchor rod construction is performed on the left side and the right side of the tunnel section B; and S12, re-spraying is performed on the left side and the right side of the tunnel section B. The construction method has the advantages of being stable, reliable, high in safety, capable of preventing sedimentation and capable of improving construction quality and efficiency.
溶洞暗河环境隧道施工的隧道正洞侧边区域施工方法，包括S1：将隧道A段开挖至连通溶洞；S2：对暗河进行改道；S3：对溶洞进行回填；S4：对溶洞洞壁进行防护处理，并在洞壁上均匀施作多根锚索；S5：对溶洞进行满填，并使锚索与满填后的回填体连接；S6：对回填体开挖形成隧道B段；S7：在隧道B段的左侧和右侧进行测量放样；S8：在隧道B段的左侧和右侧进行机械开挖；S9：在隧道B段的左侧和右侧进行基面处理；S10：在隧道B段的左侧和右侧进行混凝土初喷；S11：在隧道B段的左侧和右侧进行锚索和锚杆施工；S12：在隧道B段的左侧和右侧进行复喷。具有稳定可靠、安全性高、能防止沉降、可提高施工质量和效率的优点。
