The invention discloses an overhaul structure and a detection method for a service gate of an overflow surface bay. The overhaul structure comprises a hoisting system, a transfer system, a transfer platform, a reverse hook gate slot, a stop log and radial gates, wherein a gate pier is arranged on a dam, the gate pier is provided with the reverse hook gate slot, the stop log is arranged at one endof the reverse hook gate slot, the radial gates are arranged at the other end of the reverse hook gate slot, the hoisting system is arranged at the top of one end of the reverse hook gate slot, the transfer system is arranged at the top of the other end of the reverse hook gate slot, and the transfer platform is arranged on the side wall of the transfer system. There is no need to modify the shapeof an original dam body, and meanwhile a portal crane rail girder is omitted; a sealing plate is arranged at the lower end of a reverse hook type steel rail as a supporting stop log gate, a traditional bottom sill device is not needed any longer, and the time for underwater construction operation is omitted or shortened; and the service gate is convenient to operate and run, good in operability and flexible in operation.
本发明公开了一种溢流表孔工作闸门的检修结构及检测方法;包括:吊装系统、转运系统、转运平台、反钩门槽、叠梁闸门、弧形闸门;大坝上设置有闸墩,闸墩上设置有反钩门槽,反钩门槽一端设置有叠梁闸门,反钩门槽另一端设置有弧形闸门,反钩门槽一端顶部设置有吊装系统,反钩门槽另一端顶部设置有转运系统,转运系统侧壁设置有转运平台。对原坝体体型不需做修改,同时省去了门机轨道大梁;在反钩式钢轨下端部设封板作为支承叠梁门,从而不需要传统的底槛装置,免除或缩短了水下施工作业的时间;闸门操作运行方便,可操作性好,运行灵活。
