Lift the column, and when the bottom of the column is 0.5 ~ 1m higher than the foundation bolt, make the flange at the bottom of the column directly above the foundation bolt, and the adjusters should stabilize the root of the column, make the bolt hole of the flange of the column align with the foundation bolt up and down, and then slowly lower the column, so that the column can be seated on the foundation flange smoothly. After the column falls smoothly, screw the anchor bolt and nut diagonally.
