10. A method for installing steel bars by using the tunnel two-lining steel bar prefabricated module assembly trolley as claimed in claim 5, which is characterized by comprising the following steps:
s1, early-stage preparation work, namely determining that the section steel bar contour is consistent with the lining contour, and measuring and lofting the trolley walking line type and the trolley space;
S2, moving the trolley, starting a hydraulic rod (33), enabling a travelling wheel (35) to extend out of a supporting seat (19), and moving the trolley to a designated position;
s3, positioning a trolley, after the central line of the trolley is overlapped with the central line of the tunnel, contracting the hydraulic rod (33) to enable the travelling wheel 35 to retract into the supporting seat (19), and fixing the trolley to a designated position;
s4, lifting the platform roof, and starting a power cylinder (17) to enable the longitudinal steel bar clamp (10) and the circumferential steel bar clamp (9) to be attached to the inner wall of the tunnel;
s5, binding the steel bars, prefabricating and processing the second lining steel bars in a factory, binding the section steel bars in a hole, enabling workers to walk on the panel (8) through a walking stair (16), placing the section steel bars (13) on a lifting seat (23), starting a driving motor (25) of a lifting assembly (20), conveying the section steel bars (13) on the panel (8), positioning and fixing the steel bars according to the positions of annular steel bar clamps (9), and connecting the section steel bars (13) through special-shaped sleeves (15);
S6, system conversion, namely connecting reserved steel bars of inverted arches on two sides after the steel bar segments are assembled, starting a power cylinder (17), and enabling the trolley to fall, wherein the stress state is changed from the stress of the trolley to the stress of the whole two-lining steel bar structure;
S7, the trolley descends and exits, after the system conversion is completed, a hydraulic rod (33) is started, a travelling wheel (35) extends out of the supporting seat (19) and moves to a construction position at the next stage until all tunnel reinforcing steel bars are installed.
