[0002] In a highway project in Chongqing, the main bridge is a 40-meter-span T-beam bridge. The main beam is a structure that is simply supported first and then continuous. The bridge deck is composed of 7 T-beams, and the total bridge deck width is 15m. In an area called a certain interchange, there are several ramp bridges connected to the main bridge. The bridge width is widened from 15m to 27m, and the number of beams is increased from 7 to 12.
[0003] Due to the delay in the erection of beams in the ramp area, the beam segments connecting this area with the main bridge have not yet been erected. The transverse track of the bridge-erecting machine must be placed at the end of the erected beam segments, resulting in the main bridge's bridge-erecting machine being unable to move horizontally to the widened area.
[0004] At present, the construction specifications all start from the abutment and erect the beams one span at a time along the longitudinal direction of the bridge. In this variable amplitude area, and without the erection of ramp beams, the fulcrum in the bridge erector has no installation position (suspended in the air) and cannot be moved horizontally. There are no relevant regulations on how to erect the beams. And no relevant methods can be found in the domestic public information. The bridge crane is 40 meters above the ground. It is very costly and posing safety hazards to erect a horizontal support for the bridge crane from the ground. Utility Model Content
