Karst cave section full-filling ventilation method based on karst cave underground river environment tunnel construction
The invention discloses a karst cave section full-filling ventilation method based on karst cave underground river environment tunnel construction. The karst cave section full-filling ventilation method comprises the following steps that S1, a tunnel section A is excavated to communicate with a karst cave; S2, an underground river is subjected to course change, so that the underground river does not flow through the karst cave; S3, the karst cave is backfilled until the karst cave is backfilled to the foundation surface of the tunnel; S4, the cave wall of the karst cave is protected, and a 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, two axial flow fans are arranged at an inlet of the tunnel section A, and one or two axial flow fans are started for press-in type ventilation; S7, two axial flow fans are arranged outside the opening of a horizontal pilot cave, and one or two axial flow fans are started for press-in type ventilation; and S8, two axial flow fans are arranged in a transverse cave, and one or two axial flow fans are started for press-intype ventilation. The karst cave section full-filling ventilation method has the advantages of being stable, reliable, high in safety, capable of preventing sedimentation and good in ventilation effect.
一种基于溶洞暗河环境隧道施工的溶洞段满填通风方法，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，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：在隧道A段进口设置2台轴流风机，启动其中一台或两台轴流风机进行压入式通风；S7：在平导洞洞口外设置2台轴流风机，启动其中一台或两台轴流风机进行压入式通风；S8：在横洞内设置2台轴流风机，启动其中一台或两台轴流风机进行压入式通风。具有稳定可靠、安全性高、能防止沉降、通风效果好的优点。
