摘要
合理运用注浆技术可以有效地提高公路桥梁与隧道围岩结构的抗渗能力与稳定性,保障工程建设的安全性,提高公路桥梁隧道的耐久性和稳定性。本文结合某桥梁隧道工程实例,梳理不同注浆材料的优缺点并对材料方案作出选择,并逐一阐述隧道二衬施工不同阶段中注浆技术的具体应用,并给出了相应的质量保证方法,进一步为桥隧加固工程建设提供支持。
The rational application of grouting technology can effectively improve the permeability resistance and stability of surrounding rock structures of highway bridges and tunnels,ensure the safety of engineering construction,and improve the durability and stability of highway bridges and tunnels.In this paper,the advantages and disadvantages of different grouting materials are sorted out and the material scheme is selected based on a bridge and tunnel project.The specific application of grouting technology in different stages of tunnel secondary lining construction is described in details,and the corresponding quality assurance methods are given to further support the construction of bridge and tunnel reinforcement projects.
