External control construction method of super high-rise building core tube shaft net

The invention relates to a construction method, in particular to an external control construction method of a super high-rise building core tube shaft net, and aims at solving the problem of vertical accuracy control of super high-rise building core tube construction and providing the external control construction method of the super high-rise building core tube shaft net. The external control construction method comprises the steps of arranging a multilevel control net composed of control points within peripheral orientations of a building under construction, performing projection measurement on a building structure from projection faces, accurately positioning the shaft net with a tube structure to ensure that errors are not upward transferred and a core tube is constructed at high perpendicularity accuracy. The external control construction method utilizes a total station to perform lofting so as to externally control the perpendicularity of the core tube, and measured data deviation caused by frequent change of vertical transmission control points in a transitional method is avoided. The errors are not upward transferred, the core tube is constructed at high perpendicularity accuracy, the practical engineering requirement is met, the construction quality is ensured, the project progress is accelerated, and good economic and social benefits can be obtained.
