STEEL PIPE PILE FOR ROTATION PRESS FIT AND PRESS FIT CONSTRUCTION METHOD USING STEEL PIPE PILE

摘要

PROBLEM TO BE SOLVED: To provide a steel pipe pile for rotation press fit which improves construction speed and reduces construction cost.;SOLUTION: The steel pipe pile for rotation press fit includes a cylindrical steel pipe pile 12 having a plurality of drilling bits 13 formed circumferentially on the lower end of the pile 12, and a drilling rib 14 which is so fixed inside the steel pipe pile 12 as to be point symmetry with regard to the center of the steel pipe pile 12 and can be rotatively press fitted or press fitted together with the steel pipe pile 12. One or a plurality of the drilling ribs 14 are arranged on a plane at each step, and one or plurality of steps for fixing the drilling ribs 14 may be provided. The drilling rib 14 may have a cutter blade formed on its lower end, the cutter blade having an edge sloped against the vertical.;COPYRIGHT: (C)2008,JPO&INPIT
