| 摘 要： | 水工建筑物伸缩缝止水老化失效是引起伸缩缝渗漏水的一个重要原因。常庄水库泄洪洞伸缩缝极不规则且止水均已老化，渗漏严重。用水溶性聚氨脂灌浆，双组分聚硫密封胶填注伸缩缝处理取得了很好的效果。

| Abstract: | Watertight seal ageing of expansion joint of hydraulic structure is one important factor resulting in the expansion joint leakage. The watertight seal of Changzhuang reservoir spillway tunnel is irregular and ageing, having caused severe leakage. By adopting water-soluble polyurethane grouting technique of filling the expansion joint with two-component polysulfide sealant, the leakage has been effectively controlled. |
