Fiber-constrained composite reinforced concrete prefabricated pipe pile and construction method

The invention belongs to the technical field of offshore power transmission tower foundation engineering, and particularly relates to a fiber-constrained composite reinforced concrete prefabricated pipe pile and a construction method.The fiber-constrained composite reinforced concrete prefabricated pipe pile is formed by splicing a ground pile, a plurality of connecting piles, a plurality of internal connecting assemblies and a top pile, connection is convenient, and the construction efficiency is improved. Internal connecting assemblies are arranged between every two adjacent connecting piles, between the top pile and the connecting piles and between the ground pile and the connecting piles, the structural strength of the pile body connecting positions can be effectively improved, meanwhile, external reinforcing assemblies are arranged on the outer sides of the pile body connecting positions, the structural strength of the pile body connecting positions is further improved, and the service life of the pile b
