综合处理技术在混凝土坝水平施工缝渗水处理中的应用

Application of Comprehensive Treatment Technology in Seepage Treatment of Horizontal Construction Joints of Concrete Dams

水平施工缝渗水是水工混凝土建筑物常见的主要病害之一。本文结合实际工程,采用湿法注胶和扩大截面加固相结合的综合渗漏处理技术,能快速有效地解决混凝土坝水平施工缝渗漏问题,增强水平施工缝上下层混凝土粘结强度,提升坝体混凝土的耐久性和整体性,排除大坝因渗漏带来的结构安全隐患。

Water seepage in horizontal construction joints is one of the most common diseases of hydraulic concrete buildings. In this paper, combined with practical engineering, a comprehensive seepage treatment technology with wet glue injection and expanded the cross section reinforcement is studied, which can quickly and effeetively solve the leakage of horizontal construction joints in concrete dams and enhance the bonding strength between upper and lower concrete of horizontal construction joints, improve the durability and integrity of the dam concrete, and eliminate the structural safety hazard caused by the leakage of the dam.
