Then, when a new lightweight steel sheet pile P is inserted into the chuck mechanism 10, the chuck mechanism is operated by a conventional crane or the like.
It is not necessary to hang it above 10 and the lightweight steel sheet piles P can be arranged side by side in advance in a vertical line and inserted into the chuck mechanism 10 in sequence for construction. Therefore, it is possible to reduce the construction time, which is wasteful for crane lifting work. Further, even when the lightweight steel sheet pile P is pulled out, the lightweight steel sheet pile P in the chuck mechanism 10 can be quickly removed from the open portion 17 of the chuck mechanism 10 without lifting it with a crane or the like. Further, the chuck mechanism 10 can be separated from the lightweight steel sheet pile P during the drawing of the lightweight steel sheet pile P. Therefore, the remaining pulling work during the pulling is performed by a crane or the like, during which the chuck mechanism 10 can prepare for the next pulling work of the light weight steel sheet pile P, so that the construction time can be shortened.

As described above, in this embodiment, since the web Pw of the lightweight steel sheet pile P and the connecting portion Pm of the grip Pg are held, the stability at the time of holding is significantly improved. In other words, since both ends of the lightweight steel sheet pile P are held at two horizontal positions at the same time, the chuck mechanism 10 holds the lightweight steel sheet pile P during the press-fitting / pulling-out work while self-propelled on the pile row. When the whole apparatus A is supported by the lever, the inclination of the apparatus A can be prevented.
