Manufacturing method of super-large eccentric half-range steel-concrete combined box girder
The invention relates to a manufacturing method of a super-large eccentric half-range steel-concrete combined box girder with the length of 32.25 m, the width of 17.8 m and the weight of more than 539 tons. The manufacturing method comprises the following steps that a left eccentric half-range steel-concrete combined box girder and a right eccentric half-range steel-concrete combined box girder are integrally spliced; a prefabricated concrete bridge deck slab is hoisted and assembled through an ultra-long hoisting type frame type hoisting tool; a transverse wet joint of the half prefabricated bridge deck slab is constructed; four beam transporting flatcars are connected in parallel to synchronously support and transport left and right half-range steel-concrete combined box girders for integral tire discharge; an integrated supporting pier support tool system is used for supporting eccentric overweight half-range steel-concrete combined box girder segments; four beam transporting flatcars are used for transporting the eccentric sections in parallel; rigid supporting piers are used for supporting and controlling deformation of the half-range steel-concrete combined box girder during large-volume wet joint construction; the half section is transported and supported by using four parallel beam transporting flatcars and a supporting system to carry out subsequent sanding and coating construction; the integrated supporting pier support tool system and the combined type multi-surface stool are used for supporting the segments, and it is guaranteed that the eccentric segments are stably supported in the transportation process.
本发明涉及一种长32.25m，宽17.8m，重量超过539吨的超大偏心半幅钢混组合箱梁制造方法，包含以下步骤：左右偏心半幅钢混组合箱梁整体总拼；超长抬吊式框式吊具吊装组装预制混凝土桥面板；半幅预制桥面板横向湿接缝施工；利用四台运梁平车并联，同步支撑运输左右半幅钢混组合箱梁整体出胎；利用集成支撑墩支架工装系统支撑偏心超重半幅钢混组合箱梁节段；利用四台运梁平车并联运输偏心节段；利用刚性支撑墩支撑控制半幅钢混组合箱梁大方量湿接缝施工时的变形；利用四台并联运梁平车及支撑系统运输和支撑半幅节段进行后续的打砂、涂装施工；利用集成支撑墩支架工装系统及组合式多面凳支撑节段，保证偏心节段运输支撑稳固。
