Based on the bolt circle jig for double-layer Registration Board, the two annular plate spacing is not less than 100 mm, the bolt is not much of the exposed length. Two-tier registration plate a steel tube welded to the center with angles.

Uses the double-decked localization board to the circular foundation bolt adjusting clamp, two ring-like board spacings are not smaller than 100mm, is not bigger than the bolt to appear externally the length.Between two localization boards uses the steel pipe welding, among the circle uses the angle

Bolt spacer-fold positioning the circular base plate and two floors of annular plates spaced not less than 100mm, is not greater than the exposed length of the bolt. Between the two layers of the locating plate steel pipe welding, round angle connection in the middle.
