AI Technical Summary

Technical Problem

In the prior art, it is difficult for large pipe piles to evenly wrap fibers and ensure uniform resin coating, resulting in uneven performance of composite piles and unsolid bonding of fibers.

Method used

Using a rotatable rotation ring and prepreg unit, the prepreg unit rotates along the circumference of the pipe pile and rotates with respect to the rotation ring, maintaining a constant angle, combining the variable speed gear set and the angle holding unit to ensure that the prepreg liquid evenly covers the fibers and the fibers are wound evenly around the outer circumference of the pipe pile.

Benefits of technology

The uniform winding of fibers on the outer periphery of the pipe pile and the uniform coating of resin are achieved, which enhances the corrosion resistance, impact resistance and soil friction resistance of the composite pile.

Abstract

The invention discloses a fiber winding mechanism and a manufacturing device of a composite pile. The fiber winding mechanism comprises a rotatable rotating ring, a fiber winding mechanism and a fiber winding mechanism, wherein a winding hole allowing a pipe pile to penetrate through is formed in the middle of the rotating ring; the pre-impregnation unit is rotatably arranged on the rotating ring and rotates along with the rotating ring in the circumferential direction of the pipe pile so as to wind fibers to the outer surface of the pipe pile; wherein the pre-impregnation unit rotates along the circumferential direction of the pipe pile along with the rotating ring, and the pre-impregnation unit can rotate relative to the rotating ring, so that the included angle between the pre-impregnation unit and the horizontal plane is kept constant. According to the composite pile, the fibers are firmly bonded to the peripheral wall of the pipe pile, the corrosion resistance, impact resistance and soil friction resistance of the composite pile can be improved, meanwhile, the presoaking pool is always kept horizontal or forms a constant included angle with the horizontal plane, and leakage of presoaking liquid is avoided.
