JETTING APPARATUS FOR SUPPLYING LIQUID OR FLUID SOLIDIFYING MATERIAL, STEEL PILE USING THE SAME, CONSTRUCTION METHOD OF STEEL PILE, AND FOUNDATION PILE

摘要

PROBLEM TO BE SOLVED: To provide a steel pipe pile, an apparatus used for the steel pipe pile, a construction method of the steel pipe pile, and a foundation pile.;SOLUTION: The steel pipe pile 1 is formed by arranging and fixing a metal outer pipe 7 having jet holes 6 in the tip part and a circumferential sidewall, in a pile axis direction on the outside of a steel pipe pile body 2, fitting a tubular valve element 8 for supplying liquid, slidably to the inside of the metal outer pipe 7, and providing the tip part and the peripheral sidewall of the tubular valve element 8 for supplying liquid, with holes for connection to the inlet 5a side of the jet holes, and a wall part for blocking the inlet side of the jet holes. The jetting apparatus 22 for supplying a fluid solidifying material includes the metal outer pipe 7 and the tubular valve element 8 for supplying liquid. The steel pipe pile 1 is used to jet water or a material cured with time such as cement milk from the jet holes in the tip part of the metal outer pipe 7 and to jet the material cured with time from jet holes in the side wall to construct the steel pipe pile 1 and to construct the foundation pile.;COPYRIGHT: (C)2011,JPO&INPIT
