PILE COLUMN BUILT-UP DEVICE

摘要

PROBLEM TO BE SOLVED: To solve problems in a conventional pile column built-up device causing dispersion in the height of a plurality of pile columns after erected and incapable of ensuring accuracy in the erected positions of the pile columns. SOLUTION: This pile column built-up device is provided with a fixed base 2 fixed to the ground 7; a frame 3 equipped with a pile column perpendicularity adjusting mechanism 6 and provided separately from the fixed base; a frame fixing position adjusting mechanism 4 fixing the frame to the fixed base and making the fixing position changeable; and a pile column height adjusting mechanism 5. The pile column height adjusting mechanism 5 is formed of an active body (a piston 30A of a hydraulic jack 30) provided corresponding to a ground fixed side part (the frame 3) and the pile column 25, and a pressure receiving body 31 receiving the pressure of the active body. The pressure receiving body 31 follows the vertical movement of the active body to change the height of the pile column 25. COPYRIGHT: (C)2006,JPO&NCIPI
