Lateral prefabricated yard girder erection construction method
The invention provides a lateral precast yard girder erection construction method which comprises the following specific steps: step 1, erecting a gantry crane rail bracket, erecting a first hole precast beam by using a gantry crane, and reinforcing and connecting the erected precast beams; secondly, a transverse bridge direction walking track is laid on the top face of the erected precast beam, and a beam stopping platform is erected in the large mileage direction; thirdly, a bridge girder erection machine is assembled on the top face of the erected precast beam, a gantry crane rail support on the small mileage side is dismantled, and hole passing operation is conducted after the bridge girder erection machine is assembled; first holes of the precast beams are erected through a gantry crane, the other precast beams are erected through a bridge erecting machine, and the erecting methods of all the holes are basically the same. In the erecting process of the precast beam, the bridge-direction traveling rails of the beam transporting flatcars on the bridge floor synchronously follow up, the reversing mode of the beam transporting flatcars is easy to operate, reversing is rapid and convenient, and the construction time is effectively saved.
本发明提供一种侧方预制场架梁施工方法，具体步骤为：步骤一：搭设龙门吊轨道支架，利用龙门吊架设第一孔预制梁，并对已架设的预制梁进行加固连接；步骤二：在已架设的预制梁顶面铺设横桥向行走轨道，在大里程方向搭设停梁平台；步骤三：在已架设的预制梁顶面拼装架桥机，拆除小里程侧的龙门吊轨道支架，架桥机拼装完成后进行过孔作业；本发明中预制梁第一孔采用龙门吊架设，其余预制梁均采用架桥机架设，各孔架设方法基本相同。在预制梁架设的过程中，桥面上运梁平车的顺桥向行车轨道同步跟进，本发明运梁平车换向方式操作简单，换向快速且便捷，有效的节约了施工时间。
