基于冻融条件下隧道工程防水注浆机理与施工技术分析

Analysis of Waterproof Grouting Mechanism and Construction Technology of Tunnel Engineering Based on Freeze-thaw Condition

冻融条件下,隧道工程受冻害等因素影响,围岩、结构缝等部位很容易出现渗水现象,隧道安全无法保证。防水注浆是治理隧道渗漏问题的工程措施之一,利于提高隧道工程质量。以隧道工程为研究对象,结合大量文献资料,分析了冻融条件下的隧道工程防水注浆机理。同时,以结合具体的工程实例,探讨了隧道工程防水注浆施工技术。

Under the condition of freezing and thawing, the tunnel project is affected by frost damage and other factors. Water seepage is prone to occur in the surrounding rock and structural joints, and the tunnel safety can not be guaranteed. Waterproof grouting is one of the engineering measures to solve the problem of tunnel leakage, which will help to improve the quality of tunnel engineering. Taking the tunneling project as the research object and combining with a large amount of literature data, the tunneling waterproof grouting mechanism under the condition of freezing and thawing is analyzed. At the same time, combined with specific engineering examples, the waterproof grouting construction technology of tunnel engineering is discussed.
