Abstract
The utility model discloses an anti-vibration foundation spiral ground pile. The anti-vibration foundation spiral ground pile is characterized in that a pile pressing face is arranged on a steel pipe base body, the lower end of the steel pipe base body and the large-diameter end of a conical body are connected in a smooth mode through a transition face, the conical body and at least one part of the steel pipe base body connected with the conical body are provided with spiral blades, the outer wall of the steel pipe base body and the outer wall of the conical body are provided with anti-vibration grooves, and a fastening bolt is welded to the pipe wall of the upper end of the steel pipe base body. When the anti-vibration foundation spiral ground pile is used, installation work of a foundation is finished under the guidance of a butterfly-shaped guiding head and through a spiral piece under the action of torsion, when the pile pressing face, a second pile pressing face and an auxiliary pile pressing face vibrate, soil exerts downward pressure on the pile pressing face, the second pile pressing face and the auxiliary pile pressing face, the contact area between the steel pipe base body and the soil is enlarged by the anti-vibration grooves, and the anti-vibration grooves exert downward force on the steel pipe base body when vibrate. The anti-vibration foundation spiral ground pile has the advantages that the installation technology is simple, shock resistance, drawing force and bearing force are strong, and construction on hard and other complicated grounds can be achieved. The anti-vibration foundation spiral ground pile is particularly suitable for being used for regions where the ground vibration frequency is large.
