大跨度旋转扇形门在吴淞江工程上的应用

Application of large-span rotating sector gate in Wusongjiang Project

以吴淞江整治工程某高等级航道大孔径闸工作门作为研究对象,调查并总结已建大跨度闸门的运转特性及各自特点,提出了一种新型的大跨度扇形旋转门设计方案,从技术上及经济上对各门型进行门型比选,最终选定大跨径扇形旋转门方案。结合工程实际需求及设计工况对大跨径扇形旋转门的设计进行了介绍,为类似工程闸门选型及设计研究提供借鉴。

Taking the working gate of large aperture gate in a high-grade channel of Wusong River Regulation Project as the research object,the operation characteristics and respective characteristics of typical large-aperture gate are investigated and summarized.A new design scheme of large-aperture sector rotating gate is put forward.By comparing and selecting each gate type technically and economically,a large-span sector rotating gate scheme is finally selected.The design of large span sector rotary gate is introduced in combination with actual engineering requirements and design conditions,which provides a reference for gate type selection and design research of similar projects.
