摘　　要：针对三峡工程排漂孔及泄洪孔过流面墙壁的检修分别提出了多种专用检修装备方案。经过分析比较,得出安全合理的检修装备方案。排漂孔检修方案:闸室段侧墙用升降台车,斜坡段侧墙采用单梁吊篮,排漂孔底板采用双侧单台车;泄洪深孔检修方案:闸室段和斜坡段侧墙采用升降台车检修,底面与排漂孔检修方案相同。Due to the characteristics of the flow surfaces and side walls of the drift holes and flood discharge holes in Three Gorges Dam, special equipment is required in their maintenance and repairing.A comparison of the equipment schemes is carried out and the most reasonable and safest scheme is selected.For drift holes, the lifting platform is a-dopted for the gate chamber sidewalls, while the single-beam hanging basket is adopted for the sidewalls of slope seg-ments, and the double-side single lifting platform for bottom plates.For flood discharge holes, the lifting platform is a-dopted for both the gate chamber and the slope segments, while the double-side single lifting platform is selected for bot-tom plates.
