城市地下工程变形缝渗漏水治理施工技术研究

Research on Construction Technology for Water Leakage Treatment of Deformation Joint in Urban Underground Engineering

城市地下工程变形缝易出现渗漏水等质量问题,不仅治理难度高,并且对地下工程的正常运营影响较大。针对城市地下工程变形缝渗漏水治理的问题,以天津地区的几个工程实例,主要介绍了采用注浆封堵、再造变形缝、预留排水措施和表面处理等治理工艺措施,效果良好,对于减少地下工程的渗漏水问题意义重大,也为类似工程缺陷治理提供借鉴经验。

Deformation joints of urban underground engineering are prone to quality problems such as water leakage,which not only has high difficulty in governance,but also has a greater impact on the normal operation of underground engineering.Aiming at the problem of water leakage treatment of deformation joints in urban underground engineering,this article mainly introduces the treatment technology measures such as grouting plugging,reconstruction of deformation joints,reserved drainage measures and surface treatment with several engineering examples in Tianjin.The effect is good.It is of great significance to reduce the leakage of underground engineering,and also provides reference experience for the treatment of similar engineering defects.
