<P>PROBLEM TO BE SOLVED: To provide a reinforcement material coupling device which makes a natural ground reinforcement material driven without disturbing the ground to the utmost, which makes a frictional force against the ground sufficiently exerted by suppressing rotation of the natural ground reinforcement material after the natural ground reinforcement material is driven, and which enables simple construction. <P>SOLUTION: After a natural ground reinforcement material (6) is driven into a ground (2) by a reinforcement material driver (10), a rotation inhibition mechanism (11) for inhibiting the natural ground reinforcement material (6) from coming off by rotating is installed on a head (6H) of the natural ground reinforcement material (6) protruding from a wall surface (3) of the ground (2). <P>COPYRIGHT: (C)2013,JPO&INPIT |
