介绍了寨子沟2#特大桥深水桩钢护筒沉设技术、深水露岩钢护筒沉设方法、钢护筒沉设倾斜处理方法。同时,结合宣阳寨1#桥深水桩基钢护筒沉设工程实例,重点介绍了钢护筒卷制、加工,钢护筒运输,钢护筒导向架安装,钢护筒安放与焊接,钢护筒振沉控制等过程。对6#主墩深水露岩钢护筒沉设及钢护筒沉设后倾斜处理步骤和方法展开研究,为深水桩基钢护筒沉设施工的技术分析、过程控制、安全经济提供了参考。
Introduced the Zhaizigou 2 # super-bridge deepwater pile steel sheathing technology, deep exposed dew steel tube casing installation method, the steel casing sinking tilt treatment method. In the meantime, combining with the project of deepwater pile foundation steel casing protection for Xuanyangzhai 1 # Bridge, the paper introduces the rolling and processing of steel casing, the transportation of steel casing, the installation of steel casing guide, the installation and welding of steel casing, Steel casing vibration Shen control process. The 6 # main pier deep water exposed dew steel tube casing and steel casing after the settlement of the tilt processing steps and methods to study for the deep pile foundation steel casing sinking of the technical analysis, process control, safety and economy provide a reference .
