Automatic steel pipe column perpendicularity adjusting device using reverse construction method

The utility model discloses an automatic steel pipe column perpendicularity adjusting device using the reverse construction method, which comprises a support. An auxiliary adjusting steel pipe is inserted in the middle of the support, a horizontal adjusting mechanism which is used for adjusting perpendicularity of the auxiliary adjusting steel pipe is disposed on the support, and a vertical adjusting mechanism which is used for adjusting levelness of the support is disposed below the bottom of the support. Perpendicularity of steel pipe columns in a foundation pit is corrected by controlling the perpendicularity of the auxiliary adjusting steel pipe, and the automatic steel pipe column perpendicularity adjusting device is easy in operation, accurate in controlling and especially suitable for perpendicularity controlling for large-diameter long steel pipe columns.
