具备长期开通闸条件的船闸设计方案

Design scheme of long-term opened shiplock

在航道整治项目中,对承受双向水头的船闸或为满足水利部门特定时段防洪需要,有时需配套建设具备开通闸条件的船闸挡水。船闸通过能力一般小于航道通过能力,容易成为通航瓶颈,船闸的通过能力成为航道整治项目的关键。以丹金船闸为研究对象,对门机电系统、输水系统、平面布置方案进行系统分析论证和经济比选,保证航道通过能力的发挥和整治工程的整体效益,对于国内平原水网地区类似项目的建设及船闸标准规范的完善均有借鉴意义。

For the channel improvement project with the shiplock enduring bilateral water head action or to meet the needs of specific-period flood control required by water administrative sector, sometimes it need be equipped with open shiplock to hold the back water. As the shiplock＇s passing capability is generally less than that of channels, which is likely to create the bottleneck of navigation, the shiplock passing capability becomes a key point of channel improvement projects. Taking Danjin shiplock as a research object, this paper analyzes and compares the electro- mechanical system of the gate, water supply system and layout plan with a view of giving reference for carrying out similar projects in water networks of plain areas and improving shiplock standards and norms.
