Abstract

[purpose]

It is an object of the present invention to provide a method for constructing a reinforced earth retaining wall using a reinforcing reinforcing material which is easy to work and has a small loss of reinforcement and is economical, easy to work and does not kink, an attachment ring on a coil, .

[Configuration]

The reinforcing member a is folded to a half length so that the parts of the rings 5a and 5b are sandwiched between the attaching hooks 9 of the front plate 11 and then the hooks 5a and 5b and the attaching hook 9 are hooked And the strands of the stiffener a are simultaneously pulled toward the stratum end face 12 in a firm manner to form a tension B is inserted and fixed to the anchor holes 4 of the clips 3a and 3b to fill the gap between the end face 12 and the front plate 11. [ It is a reinforcement soil method using a string reinforcement.
