Cone used for concrete pile and concrete pile
The invention provides a cone used for a concrete pile. The cone is formed by enclosing a cone wall and is matched with a pile body of the concrete pile and is used for being connected with the pile body of the concrete pile. The bottom outer diameter of the cone is less than the top outer diameter of the cone, the outer wall surface of the cone is a conical surface with an angle of less than 45 degrees with the central axis of the cone. The invention further provides the concrete pile, the concrete pile includes the pile body of the concrete pile and the cone used for the concrete pile, the cone used for the concrete pile is connected with the pile body of the concrete pile, and the conical surface of the cone faces the bottom of a pile hole. According to the cone, the center of the conecoincides with the central axis of the concrete pile after installation, and an included angle between the conical surface and the central axis of the concrete pile and the downward tendency of the conical surface are used; when the concrete pile sinks downward, the cone enables concrete between the hole wall of the pile hole and the conical surface to produce direct and strong extrusion around 360 degrees of the axis of the concrete pile in all directions, the concrete and the hole wall of the pile hole produce huge positive pressure, the positive pressure produces huge frictional resistance,the settlement of the concrete pile is blocked, the bearing capacity of the concrete pile is improved, and settlement is reduced.
本发明提供了一种用于砼桩的锥筒，所述锥筒由筒壁合围形成，与砼桩的桩体适配，用于连接砼桩的桩体，所述锥筒的底部外径小于锥筒的顶部外径，锥筒的外壁面为与锥筒的中心轴线呈＜45°夹角的锥面。本发明还提供了一种砼桩，包括砼桩的桩体及所述的用于砼桩的锥筒，所述用于砼桩的锥筒与砼桩的桩体连接，锥筒的锥面朝向桩孔底部。本发明提供的锥筒，安装后该锥筒中心与砼桩的中心轴线重合，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，锥筒在环绕砼桩轴线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。
