摘要 三峡水利枢纽泄洪深孔弧形工作门已安全运行20多年。闸门水封虽未到更换年限,但由于各种原因导致局部破损射水严重。通过研究水封的制作工艺,成功探索了局部硫化粘结更换水封破损段的技术。在硫化粘结过程中严格控制加热温度在130~160℃,时间在60 min以内,使硫化的接头粘结牢固,无裂口,无海绵,凸凹面不超过0.5 mm。局部硫化粘结更换方案的人工、工期是传统更换方案的1/15,省料,且效果良好。 The radial gates of deep outlets in Three Gorges Project has operated safely for more than 20 years.Although the water seals of the gates are still under the replacement age,local damages are found due to various reasons,which lead to serious water jetting.Based on an analysis of the manufacturing process of the water seals,a technology of replacing the damaged section of the water seals with local vulcanization bond is proposed and successfully implemented.During the vulcanization bonding process,the heating temperature is strictly controlled within 130~160℃,and the time within 60 minutes.Thus,the vulcanized joint is firmly bonded without crack and sponge,and the convex-concave surface within 0.5 mm.The proposed local vulcanization technology is of satisfactory performance as the labor requirement and construction period are only 1/15 of traditional replacement scheme.
