Summary:An independent H-pile constructing method for manufacturing introducing initial tensile force is provided to increase resistance against displacement and tensile force, and to increase construction height of the pile by installing PC(Prestressed Concrete) steel wires without timbers. Perforated parts are formed in the ground with predetermined depth and predetermined diameters. H-piles(100,100') are arranged with at least one PC(prestressed concrete) steel wire along a longitudinal direction and installed in the perforated parts. The PC steel wires are tightened to extend the opposite side of the side arranged with the PC steel wires of the piles. Front surfaces(F) of the extended side of the H-piles are perforated. Soil pressure is injected in rear surfaces(B) of the piles when perforating the front surfaces of the piles. Deflection stress opposed to the deflection stress caused by the tension of the PC steel wires is applied to the H-piles. The ground deflection of the H-piles is generated to the front surfaces of the H-piles.
