钢管桩支架在和龙高架桥现浇箱梁中的应用

Application of Steel Pipe Pile Trestle in Cast-in place Box Beam of Elevated Bridge

和龙高架桥现浇箱梁经过方案比较选用钢管桩支架施工。钢管桩基础以零沉降控制 ,免预压 ,施工中整体监控。支架通过吊蓝设备由下至上进行拆卸。钢管桩支架在表土为软质地基中使用充分发挥了优势 ,支架体现了较高可靠性 ,取得理想效果。

The Holong elevated bridge adopts steel pipe pile trenstle construction after the schemes comparing.Te foundation of steel pipe pile is controlled by zero settlement without preload,is surveied integrally.By means of cradle equipment,trenstle is disassembled from bottom to up.The trenstle of steel pipe pile is used in ground with soft surface soil,therefore brings superiority into full play,with higher reliability and ideal effect.
