s2: transporting the deck slab onto a lifting platform (112);
s3: fixing a driving device (12) and a lifting platform (112), and enabling the lifting platform (112) to rise to the same height as the top surface of the reinforced concrete combination beam (100) along a lifting vertical rail (110) through the driving device (12);
s4: the deck slab is transported from the lifting platform (112) through the panning channel (13) to a designated location on the top surface of the steel-concrete bond beam (100) and installed.
9. A method of laying a lifting device according to claim 8, characterized in that the lifting device (1) further comprises a small gantry crane (15),
step S1, further comprising:
two sliding rails (101) are respectively arranged on the top surface of the reinforced concrete combination beam (100) along the transverse bridge towards the two side edges, and the small gantry crane (15) can be movably arranged on the two sliding rails (101) in a crossing manner;
step S4, further comprising:
after the bridge deck is transported to the top surface of the steel-concrete combination beam (100), the bridge deck is accurately lifted to a designated position through a small gantry crane (15).
10. A method of laying a lifting device according to claim 8, wherein the drive means (12) comprises a hoist (121), a block and a plurality of slings (122), the hoist (121) being arranged at the top end of the frame assembly (11), and the hoist (121) causing the lifting platform (112) to rise or fall along the lifting vertical rail (110) via the slings (122) and the block; the lifting platform (112) is also provided with a transportation trolley (14) for transporting the bridge deck;
in step S2, further comprising:
firstly, transporting the bridge deck to a lifting platform (112) positioned at the lowest part by using a transport ship, and then transporting the bridge deck to a transport trolley (14);
in step S4, further comprising:
the deck slab is transported from the lifting platform (112) to the top surface of the reinforced concrete bond beam (100) by means of a transport trolley (14).
