REACTION FRAME, AND INITIAL PRESS-IN METHOD FOR PILE AND THE LIKE

摘要

PROBLEM TO BE SOLVED: To provide a reaction frame and an initial press-in method therefor, which can enhance the accuracy of construction of a pile and the like to be pressed in, by increasing the speed of attitude control of a pile press-in/pull-out machine on the reaction frame, in the initial press-in of the pile and the like.;SOLUTION: A plurality of leveling mechanisms 20, which maintain a level by moving up and down prescribed places of the reaction frame 10, are mounted in the prescribed places of the reaction frame 10 and operated. Thus, the pile P1 is pressed in along with the acquirement of the reaction from the reaction frame 10, while the pile press-in/pull-out machine 60, which is arranged on the reaction frame 10 in the initial press-in of the pile P1, is kept in an optimum press-in attitude.;COPYRIGHT: (C)2005,JPO&NCIPI
