Point is consistent with the absolute coordinate origin constructed;
(2)Install in place using computer simulation, the absolute coordinate space X/Y/Z of actual tie point is chosen on cantilevered structure;Even
Contact coordinate chosen position is installation with regard on the outside of site;
(3)It is marked in the actual tie point position of cantilevered structure;
(4)Determine actual connection point coordinates at the scene using total powerstation, actual connection point coordinates is controlled, it is defeated in instrument
The absolute coordinate X/Y/Z for entering tie point is consistent with tie point actual coordinate;
(5)Cantilevered structure and buckling support bar are synchronously installed, and installation site, buckling support bar and knot of encorbelmenting are controlled using total powerstation
Structure is connected by flange welding.
