1溢洪道施工方案陆浑水库溢洪道工程位于拦河坝东部,距大坝东坝头约500m,溢洪道泄洪闸为3孔闸,呈“U”型结构,单孔净宽12m,闸墩长度27m(规范要求一般不超过20m,比规范要求超长7m),闸墩高程313.00m~332.00m,高度19m。左右边墩为衡重式结构,衡重台高程319.0m,宽度为10.5m(属大体积混凝土);中墩厚度3.75m,中间设2cm伸缩缝,两缝墩厚度各为1.865m。该闸建于60年代,因闸体出现多道贯穿性裂缝,除险加固采取保留原闸底板,将老闸墩拆除重建的除险加固方案。拆除内容包括:老启闭机室、工作桥、交通桥和2个边墩、2个中墩(中墩为缝墩);重建工程有新浇中墩2个,边墩2个,混凝土浇筑7683m~3;另有溢洪道进口围堰工程等。
1 spillway construction program Lu Hun reservoir spillway project is located in the east of the dam, from the dam east dam about 500m, spillway flood gate is 3 hole gate, a “U” type structure, single hole net width of 12m, gate length of 27m (specifications generally do not More than 20m, longer than the standard specification 7m), pier height 313.00m ~ 332.00m, height 19m. The left and right side piers are weighing type structure, the height of weighing platform is 319.0m, the width is 10.5m (belonging to mass concrete); the thickness of middle pier is 3.75m, the middle is 2cm expansion joint, the thickness of two-seam pier is 1 each. 865m. The gate was built in the 60s, due to multi-channel cracks occur through the gate body, to reinforce the reserve to retain the original brake floor, the old pier demolition and reconstruction of the reinforcement program. Demolition includes: old hoist room, working bridge, traffic bridge and two side piers, two in the pier (pier in the pier); redevelopment project has two new pouring pier, two pier, concrete pouring 7683m ~ 3; another spillway inlet cofferdam project.
