水溶性聚氨酯在病险水库混凝土渗水裂缝堵漏处理中的应用

Application of Sealing Concrete Leakage Cracks with Water-soluble Polyurethane in Sick Reservoir

我国病险水库众多,许多病险水库都存在混凝土裂缝渗水问题。混凝土渗水裂缝的封堵加固也是病险水库除险加固的一项重要内容,根据葠窝水库、大伙房水库和江垭大坝等工程施工的成功经验,论述了水溶性聚氨酯在病险水库混凝土渗水裂缝堵漏处理中的应用及施工方法。

There are numerous sick reservoirs in China and many of them have leakage problems caused by concrete cracks. How to seal these cracks is an important content to the reinforcement of the sick reservoirs. On the basis of successful experience of construction of Shenwo Reservoir, Dahuofang Reservoir and Jiangya Dam, the application and construction method of water-soluble polyurethane is introduced used for the seal of concrete leakage cracks in sickly reservoir.
