摘要
伸缩沉降缝漏水是水工建筑物中一种常见的质量通病。针对传统式混凝土管伸缩沉降缝的止水材料性能缺点及结构缺陷,提出采用聚乙烯泡沫塑料板作填缝板、合成橡胶作止水带、埋入式与外贴式组合止水的双层式止水结构。实践证明,这种新结构的止水效果良好,施工简单,使用期长,维修方便,全寿命周期费用少,是一种宜于推广应用的水工建筑物接缝止水处理方法。
The leakage of stretching-and-shrinking space is a frequent phenomenon in the hydraulic concrete buildings. Considering the limitation of watertight structure and watertight materials of traditional stretching-and-shrinking space in concrete pipe in the paper,a new method is given to innovate its technology. Than traditional structure , the new structure＇s watertight effect is better,its course life is longer ,its maintenance cost is cut down and its working is simple. The method is worth popularizing.
