Blade-type screw pile and screw pile driving system
The invention relates to the technical field of pile driving equipment, and discloses a blade-type screw pile and a screw pile driving system. The screw pile includes a pile end section of a screw pile, a blade is fixed to the outer circumferential side of the pile end section of the screw pile, a grouting pipe is arranged inside the pile end section of the screw pile, a grouting hole communicating with the inner part and the outer part of the pile end section of the screw pile is formed in the peripheral side of the pile end section of the screw pile, the bottom end of the grouting pipe protrudes from the grouting hole from the inner part of the pile end section of the screw pile, and the top end of the grouting pipe extends in the axial direction of the pile end section of the screw pile. The pile driving system includes a drilling rig, a grouting device and the blade-type screw pile. A grouting after pile-driving technology is realized by installing the grouting pipe in the pile endsection of the screw pile, soil around the screw pile is strengthened, and the bearing capacity of a pile foundation is improved.
本发明涉及打桩设备技术领域，公开了一种叶片式螺旋桩及螺旋桩打桩系统。该螺旋桩包括：螺旋桩桩端段，螺旋桩桩端段的外周侧固定有叶片，螺旋桩桩端段内部设有注浆管，且在螺旋桩桩端段的周侧设有连通于螺旋桩桩端段内部和外部的注浆孔，注浆管的底端由螺旋桩桩端段内部从注浆孔伸出，注浆管的顶端沿螺旋桩桩端段的轴向延伸。该打桩系统包括：钻机、注浆装置以及本发明的叶片式螺旋桩。本发明通过在螺旋桩桩端段内安装注浆管，从而实现了打桩后注浆技术，对螺旋桩周围土体的加固，提高了桩基承载力。
