大型绞吸挖泥船桥架技术发展现状及趋势

Development Status and Trend of Bridge Technology for Large Cutter Suction Dredger

绞吸挖泥船是实施水库清淤、航道疏浚、吹填成陆、港口建设等工程建设的特种工程船,安装有绞刀头、水下泵、泥管、横移滑轮等一系列设备的桥架是施工设备系统中的设计重点与难点,它对整个绞吸挖泥船的主尺度以及整体布局有着重要的影响,是绞吸挖泥船设计的重要环节。从桥架设计要求、桥架结构形式、桥架布置位置、绞刀驱动方式等方面进行分析和比较,提出了未来大型自航绞吸挖泥船桥架发展趋势和设计特点,为绞吸挖泥船桥架设计提供理论和技术参考。

The cutter suction dredger is a special engineering ship used for reservoir dredging,waterway dredging,land reclamation,port construction,and other engineering projects.The bridge structure equipped with a series of equipment such as cutter heads,underwater pumps,mud pipes,and transverse pulleys is a key and difficult design point in the construction equipment system.It has an important impact on the main scale and overall layout of the entire cutter suction dredger,and is an important link in the design of the cutter suction dredger.This article analyzes and compares the design requirements,structural forms,layout positions,and cutter driving methods of cable trays,and proposes the development trends and design characteristics of cable trays for future large self-propelled cutter suction dredgers.It provides theoretical and technical references for the design of cable trays for cutter suction dredgers.
