大型渡槽混凝土结构伸缩缝防渗处理施工技术
|
摘要
分析了山西省禹门口黄河提水工程渡槽混凝土结构伸缩缝渗漏水的原因,提出了嵌填U形橡胶止水带结合单组分聚脲表面防渗的处理方案,详细阐述了防渗处理的施工工艺。该工程修复后经过通水运行,伸缩缝渗漏问题得到了彻底解决。
The article analyzes the water leakage reasons of concrete structure expansion joints of the aqueduct of water-taking project from the Yellow River in Yumenkou, Shanxi Province, and it puts forward a plan of caulking with U type rubber waterstop combined with single component ployurea for surface anti-seepage. The paper introduces the anti-seepage application technology in details. After repairing, the project is working with water, and the leakage problems of expansion joints are solved completely.
