Tower crane installation method for foundation bolt with overlarge pre-embedded distance

The invention belongs to the technical field of building engineering construction, and discloses a tower crane installation method for a foundation bolt with an overlarge pre-embedded distance. The method comprises the steps that the distance between foundation pre-embedded bolts and the distance between fixing bolt holes of a tower crane foundation section are measured; according to the load condition of a tower crane height foundation, conversion supports are designed, each conversion support comprises a bottom plate surface, an upper panel, a connecting column, a connecting strip and a supporting strip, and the bottom plate surfaces are connected with the upper panels through the connecting columns; the supporting strips are connected with the connecting columns through the connecting strips; the conversion supports are installed on the foundation pre-embedded bolts; the upper panels of the four conversion supports are integrally calibrated; the tower crane foundation section is installed on the conversion
