PURPOSE:To prevent the non-uniform settlement of buried tubes by providing the third frame with chucks in a reciprocally movable manner to the second frame bilaterally moving on the first frame with a presser to sheathing walls. CONSTITUTION:The oil-pressure cylinder plunger device 8 of a pile penetrator set in the trench C between sheathing walls A and B is operated to set up the height of the first frame 1, or the height of a chuck 5. Pressers 4 are pressed on the sheathing walls A and B. The necessary position of the chuck 5 is adjusted by bilateral movement of the second frame 2 and/or the reciprocal movement of the third frame 3, the pile (a) is grasped by the chuck 5, the chuck 5 is pushed down by the oil-pressure cylinder plunger device 6, and the pile (a) is penetrated into the ground. |
