Karst cave section concrete spraying construction method based on karst cave and underground river environment tunnel construction
The invention relates to a karst cave section concrete spraying construction method based on karst cave and underground river environment tunnel construction. The karst cave section concrete sprayingconstruction method comprises the following steps that S1, a wall of a karst cave is cleaned, and concrete is sprayed to seal a rock surface except for an arch crown part of a tunnel section B; S2, aplurality of anchor cables are evenly constructed on the wall of the karst cave; S3, the karst cave is fully filled, and the anchor cables are connected with a fully filled backfill body; S4, the backfill body is excavated to form the tunnel section B communicated with a tunnel section A; S5, a sprayed surface of the tunnel section B is cleaned; S6, the concrete is primarily sprayed to the tunnelsection B to seal a rock surface of the tunnel section B; S7, anchor rods, steel frames and reinforcing meshes are constructed on the tunnel section B; and S8, the concrete is re-sprayed to the designed thickness. The karst cave section concrete spraying construction method has the advantages of being stable, 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喷射混凝土施工方法，包括以下步骤：S1：对溶洞洞壁进行清理，喷射混凝土封闭除隧道B段拱顶部以外的岩面；S2：在洞壁上均匀施作多根锚索；S3：对溶洞进行满填，并使锚索与满填后的回填体连接；S4：对回填体进行开挖形成与隧道A段连通的隧道B段；S5：清理隧道B段的受喷面；S6：对隧道B段初喷混凝土封闭隧道B段岩面；S7：对隧道B段施作锚杆、钢架和钢筋网；S8：复喷混凝土至设计厚度。具有稳定可靠、安全性高、能防止沉降的优点。
