Expanded-base steel pipe pile structure and construction method thereof
The expanded-base steel pipe pile structure comprises a steel pipe pile, a plurality of stiffening plates are welded to the outer side of the lower portion of the steel pipe pile, a bottom sealing plate is welded to the bottom of the steel pipe pile, a plurality of expanded-base wing plates are arranged at the bottom of the steel pipe pile in the annular direction of the steel pipe pile, the expanded-base wing plates are connected with the steel pipe pile through hinges, and conical sleeves are installed below the expanded-base wing plates. A grouting pipe is installed in the steel pipe pile, the upper portion of the grouting pipe is connected with grouting equipment, and the bottom of the grouting pipe is connected with an air bag. The overall vertical bearing capacity of the steel pipe pile is remarkably improved, and the pile length of the steel pipe pile can be effectively reduced; large equipment is not needed, operation is easy, construction is convenient and fast, and the reliability of the grouting range and the grouting effect is guaranteed through air bag type grouting; the integrity of the steel pipe pile is guaranteed, the steel pipe pile can be recycled, and the construction cost is greatly reduced; and the effectiveness and safety of the side friction resistance of the steel pipe pile are ensured.
本发明是一种扩底型钢管桩结构及其施工方法，包括钢管桩，钢管桩下部外侧焊接有若干加劲板，钢管桩底部焊接有底封板，钢管桩底部沿钢管桩环向设置有若干扩底翼板，扩底翼板与钢管桩间通过铰链连接，扩底翼板下方安装有锥形套筒，钢管桩内部安装有注浆管，注浆管上方与注浆设备连接，注浆管底部连接有气囊。本发明对于钢管桩整体的竖向承载力有显著提高，可有效降低钢管桩桩长；无需大型设备，操作简单，施工方便快捷，且气囊式注浆保证了注浆范围和注浆效果的可靠性；保证了钢管桩的完整性，钢管桩可回收利用，大幅降低工程造价；保证了钢管桩侧摩阻力的有效性与安全性。
