the method comprises the following steps: the operation personnel completes the assembly of the overpass bridge on the platform of the bank according to the direction parallel to the rail and the section-by-section assembly mode;
step two: after the line is closed, the spliced overpass bridge is pushed to a specified position, and a guide beam carrier roller (30) is fixed at the position of an axis of the overpass bridge erection at the opposite-shore station;
step three: pushing out the bridge body of the overpass bridge obliquely relative to the rail direction, and continuously adjusting the inclination until the axis of the bridge is vertical to the platform; when the bridge span module is pushed out, only one bridge span module (2) is allowed to hang out of the station;
step four: continuously pushing the bridge forwards along the direction vertical to the platform until the rollers (28) of the bridge falling device (7) at the front end of the second bridge span module (2) in front fall on the edge of the platform, adjusting the rollers (28) of all the bridge falling devices (7) on the platform to be in a braking state, and lifting the bridge falling device (7) at the foremost end of the first bridge span module (2);
step five: the restraint of the guide beam assembly (6) on the bridge section assembly (5) is removed, the guide beam assembly (6) is pushed to the edge of the opposite-shore platform, the guide beam assembly (6) is dropped on the guide beam carrier roller (30) according to the design requirement in a manual assistance mode, and a rolling moving pair is formed by the guide beam assembly and the guide beam carrier roller (30);
step six: locking the guide beam assembly (6), checking and releasing the brakes of all the walking rollers (8), pushing the fixedly connected overpass bridge and the guide beam assembly (6) until the tail ends of the fixedly connected overpass bridge and the guide beam assembly (6) reach the edge of the shore station;
step seven: continuously pushing the overpass bridge and the guide beam assembly (6) forwards to the front of the guide beam carrier roller (30), so that the originally lifted bridge falling device (7) at the front end of the bridge falls onto the opposite-shore platform;
step eight: locking rollers (28) of the bridge falling devices (7) on all the platforms, removing the guide beam carrier roller (30), releasing the locking state of the guide beam assembly (6), and withdrawing the guide beam assembly (6) and fixing the guide beam assembly on the bridge section assembly (5); then the wheel brakes of the rollers (28) of the bridge falling devices (7) on all the platforms are released, and the overpass bridge is continuously pushed forwards to the designed bridge position;
step nine: and (3) putting down the springboard assembly (1), clamping and positioning, and commanding the vehicle to pass after checking that the preset requirements are met.
