逆の手順で行える。This point will be described with reference to FIG. 5. Before the press-fitting pile P is completely pressed into the ground, the pile chuck 6 is raised to the position 6a of the imaginary line to firmly hold the pile, and the pile clamp 20 , Release 20. Then, when the pile chuck 6 is lowered, the main body 1 is relatively raised by the reaction force of the pile P. In this state, the base 2 is moved forward, and the clamp 20a in front of the base P2
The main body 1 is lowered when it reaches above. The main body 1 thus moved forward is again clamped by the clamp 20 to the pile row P.
Fix it to 1 and continue the press-fitting work of the pile. Such a body 1
The forward movement process can be performed by the same procedure as the conventional self-propelled pile driver on piles, and various methods can be considered depending on the situation, and an appropriate method can be adopted. Further, in the above-mentioned embodiment, the operation is explained only by the press fitting of the pile, but the pulling out work of the pile can be performed by the reverse procedure of the press fitting work.
