Lateral girder erection and construction method for truss double-girder type bridge girder erection machine
The invention belongs to a precast girder mounting construction method, in particular to a lateral girder erection and construction method for a truss double-girder type bridge girder erection machine. A lateral girder erection structure of the truss double-girder type bridge girder erection machine comprises two transverse moving tracks, wherein the two transverse moving tracks are respectively arranged on the tops of bent caps at two ends of a to-be-erected hole; two ends of each transverse moving track are suspended out of the bent caps; outer suspended ends of each transverse moving track are supported on temporary buttresses; a high-position gantry crane structure is arranged on the tops of the two transverse moving tracks; and a transverse moving wheel box serves as a walking system of the high-position gantry crane structure. The construction method comprises the following steps of mounting the temporary buttresses; mounting and reinforcing the transverse moving tracks; mounting main longitudinal girders; and assembling, examining and receiving the bridge girder erection machine. The lateral girder erection method of the truss double-girder type bridge girder erection machine comprises the following steps of girder conveying, girder feeding, girder lifting, transverse moving, girder falling, temporary reinforcing and welding of crossbeams among girders. By the lateral girder erection and construction method for the truss double-girder type bridge girder erection machine, the construction cost is reduced effectively, and construction safety is ensured.
