白莲崖水库泄洪中孔工作闸门是该水库泄水建筑物重要控制设备之一。闸门设计孔口7.0m×7.725m,设计水头61.45m,动水启闭。闸门为直支臂双主纵梁结构,支铰为自润滑球面滑动轴承,采用预压式转铰止水。门叶结构纵向对称分成两片,现场用高强螺栓及水密焊缝连接成整体,妥善解决了制作、运输及吊装等问题,为高水头弧形闸门设计积累了的经验。
Floodgate Bailianya reservoir flood gate work is one of the important control equipment of the reservoir drainage structures. Gate design aperture 7.0m × 7.725m, design head 61.45m, open and close the water. The gate is a straight support arm double main stringer structure, the hinge is a self-lubricating spherical plain bearing, the pre-compression type hinge to stop water. Longitudinal symmetry of the door leaf structure is divided into two, the scene with high-strength bolts and watertight welded joints into a whole, properly solve the production, transportation and hoisting and other issues for the design of high-head curved gate accumulated experience.
