唐山G205改建工程王盼庄立交桥由一座主线桥,A~H,J~K,R、S共12条匝道组成,其中C匝道有两联,F匝道、A匝道各一联钢箱梁。在钢箱梁施工前期,原材料钢板、焊条进场,横向、纵向节段钢板之间的焊接,部分焊缝的初期检测都在加工棚内成型,节段钢箱梁制作完成后运送至施工现场场地,现场场地需设置钢箱梁底座,底座的曲线、高程要满足设计图纸中钢箱梁的平面曲线及相对高程控制。然后在现场进行横向节段之间的拼装、外观涂装、焊缝检测等工作。
Tangshan G205 reconstruction project Wang Panzhuang overpass by a main bridge, A ~ H, J ~ K, R, S a total of 12 ramp, of which C ramp with two, F ramp, A ramp each with a steel box girder. In the early stage of steel box girder construction, raw materials such as steel plates and welding rods, welding between transverse and longitudinal sections of steel plates, and initial tests of some of the welded seams are all formed in the processing shed, and the steel girders of the sections are delivered to the construction site Site, the site needs to set the steel box girder base, the base of the curve, elevation to meet the design drawings of the steel box girder curve and the relative elevation control. And then assembled at the scene between the horizontal segments, the appearance of paint, weld testing and so on.
