摘要
龙湖大桥横跨棉花滩水库,主墩桩基位于河谷两侧,利用4台200t连续式千斤顶同步整体提升234.81t的主墩钻孔平台,成功解决了在库区或内陆湖地区不具备大型水上起吊设备的情况下钻孔平台的安装问题。该文着重对同步提升系统的结构设计和提升工艺进行研究,可为今后解决库区或内陆湖地区不具备大型水上起吊设备的钻孔平台安装问题提供借鉴。
The Longhu Bridge spans the Mianhuatan Reservoir,and the main pier pile foundations are located on both sides of the river valley.Four sets of 200t continuous jacks were employed to synchronously lift the 234.81t main pier drilling platform,successfully solving the installation problem of the drilling platform in where water lifting equipment can be used like reservoir and inland lake areas.This paper focused on research of the structural design and lifting techniques of the synchronous lifting system.It can provide a reference for solving such problem.
