Novel screw pile

The novel spiral pile comprises a tubular pile body, a spiral piece and a mud guard, the spiral piece is fixedly arranged at the bottom end of the tubular pile body, and the mud guard is arranged at the pile tip of the tubular pile body in a weak connection mode. According to the screw pile, a pile tip structure and a pile top structure are modified on the basis of a traditional screw pile so as to adapt to hole cleaning and grouting of a riprap pore channel. The spiral pile foundation can be applied to the riprap stratum, the bearing effect of the expanded head at the bottom of the spiral pile is achieved through built-in reinforcing steel bars and grouting of the spiral pile, and therefore the bearing capacity of the spiral pile is greatly improved, large machines do not need to intervene in the construction process, and the spiral pile foundation has the advantages of being convenient to implement, short in construction period and low in cost. 本申请公开一种新型螺旋桩，包括管桩、螺旋片和挡泥板，所述螺旋片固定设置于所述管桩底端，所述挡泥板采用弱连接的方式设置于管桩的桩
