鱼形钢管桩制造技术

本发明专利技术公开了一种鱼形钢管桩。一种是在底部封闭的钢管桩侧面从上至下依次焊接多层侧翼片，每层侧翼片为2～4个；在底部封闭的钢管桩锥形尖端侧面焊接尾翼片。另一种是在在底部开口的钢管桩侧面从上至下依次焊接多层侧翼片，每层侧翼片为2～4个；在底部开口的钢管桩下端侧面焊接一层尾翼片，尾翼片为2～4个。本发明专利技术是单桩受到扭矩作用时桩身和桩端翼片挤压土体产生较大土体反力，从而大幅提高单桩扭矩承载力。本发明专利技术改善了传统圆形钢管桩在扭矩作用下的受力特点，抗扭转能力强、稳定性好、改造成本小，可应用于近海工程、港口工程中各种结构物的基础。

Fish shaped steel pipe pile

The invention discloses a fish shaped steel pipe pile. One side of the steel pipe pile whose bottom is closed is welded with multilayer lateral wings from top to bottom, each side plate is 2~4, and the tail fin is welded at the tapered end of the steel pipe pile closed at the bottom. The other one is in the pipe in the opening at the bottom of the pile side from top to bottom welding multilayer wing, each layer is 2 ~ 4 wing; welding layer of fin on the bottom of steel pipe pile side of the lower end opening, fin is 2 ~ 4. When the single pile is subjected to torque action, the pile body and the pile end fin squeeze the soil mass to produce larger soil counterforce, thereby greatly improving the torque carrying capacity of the single pile. The invention improves the force characteristics of the traditional round steel pipe pile under the action of torque, has strong anti torsion ability, good stability and small reconstruction cost, and can be applied to the foundation of various structures in offshore engineering and harbor engineering.
