<P>PROBLEM TO BE SOLVED: To simplify a construction method, to reduce construction costs and to suppress an industrial waste generation amount, in a natural ground reinforcement earth method. <P>SOLUTION: A lower reinforcement material 11 of a reinforcement material 1 is a cylindrical steel pipe, one end 11a of which is crushed, while the interval dimension of a pair of wall surfaces 11b, 11c being reduced toward the distal end, the distal ends of the pair of wall surfaces 11b, 11c are turned into a linearly matching shape. Also, the end 11a functions as a sharp part for going into the banking of natural ground during placing. Also, on the side face of the cylindrical lower reinforcement material 11, a circular opening 11e is formed. The opening 11e functions as a discharge port for discharging grout press-fitted in the inside from the rear end side of the reinforcement material 1 to the periphery of the reinforcement material 1. <P>COPYRIGHT: (C)2012,JPO&INPIT |
