长距离小断面水工隧道施工技术研究

Research on Construction Technology of Long-distance and Small-section Hydraulic Tunnels

水工隧道工程的科学修建可有效缓解水资源紧缺问题。文章依托某水工隧道引水隧洞项目,重点分析爆破技术、开挖技术、塌方处理技术、变形处理技术和二次衬砌施工技术的实践应用要点,以期为同类型工程施工提供参考,应对开挖掘进中所面对的涌水、涌砂、地质状况复杂和塌方变形问题。

The scientific construction of hydraulic tunnel engineering can effectively alleviate the shortage of water resources.Based on a hydraulic tunnel diversion tunnel project,this paper focuses on analyzing the practical application points of blasting technology,excavation technology,collapse treatment technology,deformation treatment technology and secondary lining construction technology,in order to provide reference for the construction of the same type of engineering,and to deal with the problems of water gushing,sand gushing,complex geological conditions and collapse deformation in excavation and tunneling.
