天生桥水库金属结构设计制造与安装回顾

Review on the design, manufacture and installation of metal structures for Tianshengqiao Reservoir

大型弧门支座埋件采用一期砼浇筑是不合理的，挂钩式锁定不适用于大容量启闭机，双P型的顶水封布置形式不能满足水头高于50m的弧形工作闸门封水要求，在设计溢洪道时应留出检修门槽。

The reason of that why it is not reasonable to adopt concrete pouring for the bracket base of large scale arc gate at the first phase, why unsuitable to adopt pothook type cogged joint for the large scale hoist, why the doubleP waterseal could not meet the need of the arc gates with water head over 50 m, and why should obligate gate slots for overhauling during design the spillway are summarized in this paper.
