Transporting technology of large-span structural sheet

A transporting technology of a large-span structural sheet comprises the following steps: 1, prefabricating the large structural sheet; 2, laying a plurality of hydraulic jacking devices at a jacking point below the large structural sheet; 3, after jacking the large structural sheet to an appointed height, mounting a temporary support below the large structural sheet; 4, connecting a transporting framework with a trolley axis of a self-powered hydraulic flat car; 5, driving the self-powered hydraulic flat car below the large structural sheet, and after jacking the large structural sheet, transporting the large structural sheet out of a workshop to an advanced outfitting site; 6, driving the self-powered hydraulic flat car away, and supporting by the temporary support; 7, driving the self-powered hydraulic flat car below the large structural sheet, and after jacking the large structural sheet, transporting the large structural sheet to a spraying workshop; and 8, after finishing spraying the large structural sheet, transporting the sprayed large structural sheet out of the spraying workshop to an assembly site, and carrying out assembly operation. The transporting technology solves the problem that the existing site transporting vehicle cannot realize the transporting operation of the large-span structural sheet and realizes safe and efficient transporting operation.
