Claims

[Claims for Utility Model Registration] 1 (a) Sheet piles (Fig. 1) are held by a special device (Fig. 3) attached to a support structure (Fig. 3), and are advanced alternately. (b) The support structure (Fig. 3) is divided into two parts, each of which is moved forward by hydraulic pressure. (c) Immediately before the sheet pile 1 moves forward, install the shoring material 5 and the earth retaining sheet pile 4 at the rear of the support structure, and perform the earth retaining work. 2. At the contact surface between the sheet pile (Fig. 1) and the support structure (Fig. 2), a ball bearing piece 8 is attached to the support structure or a chevron-shaped groove 11 is provided in the sheet pile in order to facilitate sliding.
