The present disclosure discloses a fiber reinforce plastic (FRP) composite material pile prepared by an FRP composite material. The FRP composite material pile includes: an FRP winding pipe, an FRP pultrusion hollow profile, and a connecting device. The FRP pultrusion hollow profile includes an outer ring pipe, an inner ring pipe, and a plurality of reinforcing bars. The FRP pultrusion hollow profile is pultruded at one time by pultrusion equipment, and fiber materials thereof are arranged in the longitudinal direction of the pipe. The FRP winding pipe is provided with circumferential fiber materials by taking the FRP pultrusion hollow profile as a membrane, and forms a composite pipe section with the FRP pultrusion hollow profile. The inner ring shape of the cross section of the FRP winding pipe is matched with the FRP pultrusion hollow profile. The FRP connecting device includes connecting plates, connecting bars, and connecting pins.
