以某桥梁15~18号桥墩检测加固项目为工程背景,介绍了某桥梁高潮差低净空下的工具式可拆卸循环利用双壁钢围堰使用方法,该工具式可拆卸循环利用双壁钢围堰的施工考虑了涨落潮变化、桥下净空较小等环境因素,以及围堰及辅助措施的设计、制作安装。应用证明,该方法具有减少施工工期、降低成本、节能环保等特点。
以某橋樑15~18號橋墩檢測加固項目為工程揹景,介紹瞭某橋樑高潮差低淨空下的工具式可拆卸循環利用雙壁鋼圍堰使用方法,該工具式可拆卸循環利用雙壁鋼圍堰的施工攷慮瞭漲落潮變化、橋下淨空較小等環境因素,以及圍堰及輔助措施的設計、製作安裝。應用證明,該方法具有減少施工工期、降低成本、節能環保等特點。

In this paper,in the engineering background of detection and reinforcement project of the No.14~18 Pier of a bridge,the construction method of the Tool-Typed Double Wall Steel Cofferdam in the bridge of low clearance flyovers which is removable and recyclable in the spring tide of poor wa-ter is introduced.In the method,the factors,the spring tide of poor water,low clearance flyovers, and details of design and fabrication of the steel cofferdams are considered.An application example shows that the method can reduce construction time,cost,energy conservation and environmental protection..
