Tunnel main tunnel area construction method based on karst cave underground river environment tunnel construction
The invention discloses a tunnel main tunnel area construction method based on karst cave underground river environment tunnel construction. The method includes the steps that S1, a tunnel section A is excavated to be communicated with a karst cave; S2, an underground river is redirected; S3, the karst cave is backfilled; S4, the cave wall of the karst cave is protected, and anchor cables are evenly constructed on the cave wall; S5, the karst cave is fully filled, and the anchor cable is connected with a fully filled backfill body; S6, measuring and setting out are conducted on a left sectionand a right section; S7, the left section and the right section are blasted; S8, the left section and the right section are excavated to enable the left section to be communicated with the right section; S9, base plane treatment is conducted on the left section and the right section of a tunnel B; S10, concrete primary spraying and supporting are conducted on the left section and the right sectionof the tunnel B; S11, anchor cable and anchor rod construction is conducted on the left section and the right section of the tunnel B; and S12, re-spraying is conducted on the left section and the right section of the tunnel B. The tunnel main tunnel area construction method based on karst cave underground river environment tunnel construction has the advantages of being stable, reliable, high insafety, 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：对左段和右段进行测量放样；S7：对左段和右段进行爆破；S8：对左段和右段进行开挖使左段和右段贯通；S9：对隧道B左段和右段进行基面处理；S10：对隧道B左段和右段进行混凝土初喷和支护；S11：对隧道B左段和右段进行锚索和锚杆施工；S12：对隧道B左段和右段进行复喷。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。
