Construction method for erecting in-situ prefabricated railway box girder
The invention discloses a construction method for erecting an in-situ prefabricated railway box girder, which comprises the following steps of: 1, driving a girder transporting vehicle to an installed box girder, and prefabricating the railway box girder on the girder transporting vehicle in situ; 2, supporting the bridge girder erection machine on a girder surface; step 3, loading the prefabricated railway box girders by a girder transporting vehicle, moving the prefabricated railway box girders from the tail part of the bridge erecting machine to the interior of the bridge erecting machine and between a middle supporting leg and a rear supporting leg, and taking the railway box girders at a fixed point through a main crown block on the bridge erecting machine; fourthly, after beam taking is finished, the beams are erected, the beam transporting vehicle is moved out of the tail of the bridge girder erection machine, and the next section of railway box beam is prefabricated in situ; 5, crossing the bridge girder erection machine; sixthly, after crossing is completed, the third step to the fifth step are repeated till all the railway box girders are erected. The problems of low construction efficiency, single function, poor safety and the like of railway bridge box girder erection can be solved, the construction quality and efficiency are improved, and smooth proceeding of railway box girder construction is promoted.
本发明公开了一种原位预制铁路箱梁架设的施工方法，包括如下步骤：步骤一、运梁车行驶至已安装好的箱梁上，并在运梁车上原位预制铁路箱梁；步骤二、架桥机支撑于梁面上；步骤三、运梁车装载预制好的铁路箱梁从架桥机尾部移动至架桥机内部，位于中支腿及后支腿之间，通过架桥机上的主天车对铁路箱梁进行定点取梁；步骤四、取梁结束后，进行架梁，运梁车移出架桥机尾部并原位进行下一段铁路箱梁的预制；步骤五、架桥机过跨；步骤六、过跨完成后，重复上述步骤三至五，直至完成所有铁路箱梁架设。本发明可以解决铁路桥梁架设箱梁施工效率低、功能单一、安全性差等问题，提高施工质量和效率，促进铁路箱梁施工的顺利进行。
