新型单组分喷涂聚氨酯对改进蓄水大坝工程止水性的试验研究

Experimental study on improving water sealing performance of water storage dam engineering with a new single component sprayed polyurethane

以某抽水蓄能电站大坝工程混凝土面板为例,采用新型单组分喷涂聚氨酯防水涂料对改进大坝工程止水性进行试验研究,分析涂料本身性能、涂层抗渗能力、涂层附着力以及耐候性能。结果表明,该新型单组分喷涂聚氨酯防水涂料具有优异的拉伸性能、良好的耐久性能和优异的黏结性能,可有效改进蓄水大坝工程的止水性。

This study focuses on the experimental study of the application of a new single component sprayed polyurethane waterproof coating to improve the water sealing performance in water storage dam engineering,using the concrete panel of a pumped storage power station dam as a case study.The performance of the coating itself,the impermeability,the adhesion,and the weather resistance are analyzed.The results show that the new single component sprayed polyurethane waterproof coating exhibits excellent tensile performance,good durability,and superior bonding capabilities,which can effectively improve the water sealing performance of water storage dam engineering.
