Fan pile pier foundation and construction method thereof
The invention relates to a fan pile pier foundation and a construction method thereof, and discloses a fan pile pier foundation, which comprises a center pier foundation. The fan pile pier foundation is characterized in that an anchor rod pile is arranged at the bottom part of the center pier foundation, 8-12 inclined piles are arranged around the center pier foundation, a concrete pile cap is arranged at the top part of the center pier foundation, a reinforced bar at the top part of each inclined pile is connected with a reinforced bar of the concrete pile cap, the concrete pile cap is cast together with the inclined piles, and a prestressed anchor rod is arranged in the center pier foundation. The fan pile pier foundation has the advantages that the problems of insufficient bearing capacity and loess collapsibility of soft soil are solved; at the premise of meeting the domestic standard requirements, the material is saved, the construction period is shortened, the whole safety, stability and settling control property are sufficiently guaranteed, and the higher practicality is realized for the ground foundation reinforcing and foundation design of wind power generators in eastern coastal areas and northwestern collapsibility loess areas of China.
