INITIAL PRESS FIT METHOD FOR STEEL PILE, INITIAL REACTION EQUIPMENT AND INITIAL REACTION LOADING PLATFORM

摘要

PROBLEM TO BE SOLVED: To provide an initial press fit method without interruption upon completion of the initial press fit; being capable of coping with the shortage of reaction in the press fit after the second one during continuous press fit of steel pile; initial press fit method and its initial reaction method enhancing the press fit efficiency for steel pile; and an initial reaction loading platform.;SOLUTION: A power unit 3 is arranged at the front side on a travelling equipment 2, a reaction loading platform 4 is installed at the rear side on the travelling equipment 2, and on the static load type pile press fit pull-out apparatus equipped with a pile press fit pull-out machine main body 5 arranged above in a state of a clamping portion 4a of the reaction loading platform 4 held in a clamped state, the reaction loading platform 4 arranged and extended to the rear, the travelling equipment 2 is held from both the sides of the reaction loading platform 4 and is driven upward or downward by a lift arm 7 driven by the up and down cylinder 8, and the initial press fit reaction can be obtained by press fitting the reaction loading platform 4 to the ground surface, thereby providing the initial press fit method for steel pile, the initial reaction equipment and the initial reaction loading platform.;COPYRIGHT: (C)2003,JPO
