凌津滩水电站泄洪闸工作闸门及启闭机设计特点

Design features of flood-releasing service gate and hoist for Lingjintan Hydropower Station

凌津滩水电站首次采用大型盘香式启闭机启闭大型平面工作闸门,取消常规布置中的混凝土高排架,加快了工程进度,实现提前6个月发电,取得了非常好的经济效益与社会效益。自1998年下闸蓄水以来,泄洪闸已经安全运行了近5年时间,工作闸门及启闭机经历了各种洪水的考验,总体运行情况基本良好,可供类似工程借鉴。

This paper outlines the first use of large disc-type hoist for operating the large plane gate of the Lingjintan Hydropower Station. In addition, the cancellation of concrete trestle stand usually on the concrete dam brought about a speed-up of construction progress and 6-month early first power generation as well as good economic and social benefits. During five-year operation since 1998, the flood-releasing gate and hoist have experienced all kinds of flood and maintained a safe and reliable operation, presenting a sound system operation. This paper summarizes the design features of the operating flood-releasing gate and hoist, which can use for reference for the colleagues in the work of the similar projects.
