土岩组合地区富水砂层隧道施工注浆技术

本文从隧道工程施工质量不断提升的时代背景入手,对于土岩组合富水砂层隧道施工注浆技术中的技术管理与注浆材料、参数对比分析进行分析与研究。注浆工艺通过发挥浆体的粘合和密封作用,能够在很大程度上提高结构稳定性。本文首先简述了提升土岩组合地区富水砂层隧道施工注浆技术效果的重要性,同时结合香山2号隧道施工实际,分析了现阶段陇南地区富水砂层隧道施工注浆与上软下硬地层施工中存在的问题,且探究了进一步提升我国土岩组合地区富水砂层隧道施工注浆技术方案的高效性和质量的策略。

Grouting Technology for Tunnel Construction in Water Rich Sand Layer in Soil Rock Combination Area

Starting from the background of the continuous improvement of tunnel construction quality,this paper analyzes and studies the technical management and comparative analysis of grouting materials and parameters in the tunnel construction grouting technology of soil rock combination water rich sand layer.Grouting technology can improve the structural stability to a great extent by giving play to the bonding and sealing role of slurry.Firstly,this paper briefly describes the importance of improving the effect of grouting technology in the construction of water rich sand tunnel in soil rock combination area.At the same time,combined with the construction practice of Xiangshan No.2 tunnel,this paper analyzes the problems existing in the construction grouting of water rich sand tunnel and the construction of upper soft and lower hard stratum in Longnan area,It also explores the strategies to further improve the efficiency and quality of grouting technical scheme for tunnel construction in water rich sand layer in China's land rock combination area.
