摘要
The present invention is excellent in the effect of dispersing the cross-sectional force acting on the steel pipe pile head and the adhesion performance with the enlarged base concrete is improved so that the action force transmitted through the expansion base can be smoothly transferred to the steel pipe pile and at the same time through the steel pipe pile This invention relates to a steel pipe pile head reinforcement structure that is easy to install due to its solid coupling with a stuffed concrete, and a steel pipe pile head reinforcement method using the same. According to a preferred embodiment of the present invention, the steel pipe pile 10 is formed with a plurality of reinforcing hole 10a along the upper circumferential surface; A bottom plate 12 fixed to a predetermined depth of the steel pipe pile 10; A plurality of vertical reinforcing members 13 installed in the longitudinal direction along the inner circumferential surface of the steel pipe pile 10; A fixing root 14 coupling the plurality of vertical reinforcing members to each other; And a plurality of through bars 15 coupled to the steel pipe pile 10 so as to penetrate the rebar insertion holes 10a facing each other, and the vertical reinforcing member 13 includes a fixed muscle straddling protrusion for installing a fixed muscle ( 132, a steel pipe pile projection 133 to be spread over the steel pipe pile and a gap holding projection 134 for maintaining a gap with the inner surface of the steel pipe pile, each projection is to cut a portion and protrude the cut portion from the surface A steel pipe pile head reinforcement structure is provided, which is configured to protrude from a surface while forming an opening therein.
