The invention provides a cone for a concrete pile. The cone for the concrete pile comprises a top, a bottom and an outer wall face between the top and the bottom. The top of the cone is matched with apile body of the concrete pile and is used for being connected with the pile body of the concrete pile, the outer diameter of the bottom of the cone is smaller than that of the top, the outer wall face of the cone is a conical face, and the included angle between the central axis of the conical face and the central axis of the cone is smaller than 45 degrees. The invention further discloses the concrete pile. The concrete pile comprises the pile body and the cone, and after the cone is connected with the pile body of the concrete pile, the conical face of the cone faces the bottom of a pile hole. According to the cone, the center of the cone coincides with the central axis of the concrete pile after installation; by utilizing the included angle of the central axis of the conical face andthe central axis of the concrete pile and the downward inclination of the conical face, when the concrete body settles downwards, the cone generates direct and strong extrusion on concrete between thewall of the pole hole and the conical face in all dimensions around the axis of the concrete pile by 360 degrees, huge positive pressure is generated by the concrete and the wall of the pile hole, huge frictional resistance is generated by the positive pressure, settling of the concrete pile is prevented, the bearing capacity of the concrete pile is improved, and settling is reduced.
本发明提供了一种用于砼桩的锥体，包括顶部、底部及顶部和底部之间的外壁面，所述锥体的顶部与砼桩的桩体适配，用于连接砼桩的桩体，所述锥体的底部外径小于顶部外径，锥体的外壁面为锥面，该锥面与锥体的中心轴线夹角＜45°。本发明还提供了一种砼桩，包括桩体及上述锥体，所述锥体与砼桩的桩体连接后，其锥面朝向桩孔底部。本发明提供的锥体，安装后该锥体中心与砼桩中心轴线重合，利用锥面与砼桩中心轴线的夹角和锥面朝下的倾向，当砼桩向下沉降时，锥体在环绕砼桩轴线360°的全方位使桩孔孔壁与锥面之间的砼产生直接的、强烈的挤压，砼与桩孔孔壁产生巨大的正压力，正压力产生巨大的摩阻力，阻挡砼桩的下沉，使砼桩承载力提高，沉降减小。
