PURPOSE:To enable smooth driving of a concrete sheet pile, by a method wherein the side, in the rear in a driving-forward direction, of a sheet pile under driving is pressed by means of the one roller, and the rear end surface of the sheet pile is pressed by means of the other roller. CONSTITUTION:H-steels 22, being guide forms, are placed on the ground surface on both sides in a driving-forward direction of a sheet pile A. Thereafter, a roller 20, attached to the H-steel 22, is brought into contact with the side of a joint between an existing sheet pile A and the sheet pile A under driving to press it thereby, and presses the front side in the driving-forward direction of the sheet pile A under driving and the rear side in the driving-forward direction of the existing sheet pile A. By means of the other roller 21, the rear end surface in the driving-forward direction of the sheet pile A is pressed, and the sheet pile A is guided by the use of the rollers 20 and 21. This, though the sheet pile has a particular shape, enables the sheet pile to be smoothly driven as planned. |
