On-beam beam transporting construction method suitable for segmental prefabricated assembled bridge
The invention discloses an on-beam beam transporting construction method suitable for a segmental prefabricated assembled bridge, which comprises the steps of transporting beams on the bridge and feeding beams at the tail part of a bridge girder erection machine, and comprises the following specific steps: firstly, transporting prefabricated segmental beams to the tail part of the bridge girder erection machine by a beam transporting vehicle on the beams; thirdly, prefabricated segmental beams are hung at a high position, and the beams are fed to the penultimate block section by section; secondly, sequentially hanging the last fourth segment precast beam, the third segment precast beam, the first segment precast beam and the second segment precast beam in place; then, adjusting the prefabricated segmental beams by using a bridge girder erection machine; and finally, splicing the segmental precast beams by glue, tensioning, grouting and falling the beams to complete the erection of the whole-hole segmental precast beams. According to the construction method, the engineering construction cost of the segmental prefabricated assembled bridge can be effectively reduced, the construction progress is accelerated, and the influence on the surrounding environment is reduced.
本发明公开了一种适用于节段预制拼装桥梁的梁上运梁施工方法，“桥上运梁，架桥机尾部喂梁”，具体步骤如下：首先，运梁车在梁上将预制节段梁运输至架桥机尾部；接着，预制节段梁高位吊挂、逐段喂梁至倒数第5块；其次，依次将倒数第4块、第3块、第1块、第2块节段预制梁悬挂到位；然后，使用架桥机调整预制节段梁；最后，节段预制梁胶拼、张拉、灌浆、落梁，完成整孔节段预制梁架设。该施工方法可以有效降低节段预制拼装桥梁的工程建设费用，加快施工进度，减少对周边环境的影响。
