在泄水闸的水工试验中,作者曾遇到两个工程:一个是汉江杜家台分洪工程,另一个是广东省的芦苞闸。这两个闸在结构上有着很大的差别,可以代表两种典型。杜家台为新建工程,属于各孔一致的多孔闸典型(30孔);芦苞闸为修复工程,闸孔较少,且中孔为一滚水坝的混合结构,属于不一致的较少孔闸典型(6孔及一坝)。由于以往曾有某闸在运用操作过程中,因发生闸门启闭机失灵,造成个别闸门开后不能关闭,导
In the sluice hydraulics test, the author has encountered two projects: one is the Dujiantai flood diversion project in Hanjiang River and the other is the Lujiabu in Guangdong Province. The two brakes are very different in structure, can represent two kinds of typical. Dujiatai is a new construction project, which belongs to the typical porous hole (30 holes) with the same hole. For the restoration project, the LuBaZhong gate has fewer gate holes and the mesopore is a mixed structure with a rolling dam, which is inconsistent with less hole gates Typical (6 holes and a dam). In the past, there was a gate in the operation process, due to the gate hoist failure, resulting in an individual gate can not be closed after the opening, guide
