Block prefabrication construction method for section steel box girder of cable-stayed bridge
The invention discloses a block prefabrication construction method for a segment steel box girder of a cable-stayed bridge, which comprises the following steps of: transversely dividing a standard segment into three installing and welding modules for manufacturing, manufacturing a temporary matching piece, and erecting a jig frame in a pre-splicing field; then sequentially hoisting three assembly welding modules, transversely placing the three assembly welding modules on the jig frame and aligning the three assembly welding modules so as to complete the in-place step of a group of standard sections to be assembled; the step of placing the standard sections to be assembled in place is cyclically carried out, then the temporary matching pieces are used for matching the three installing and welding modules into the standard sections, and the multiple standard sections are matched into the steel box girder combination sections; then, connection of the temporary matching pieces is removed, a set of standard sections at the rearmost end of the jig frame is left, the rest of the installing and welding modules are transferred to the next construction area one by one through a beam transporting vehicle, and the set of standard sections at the rearmost end of the jig frame is moved to the front end of the jig frame; and finally, the step S2 and the step S3 are repeated, and block prefabrication construction of the steel box girder is completed. The purpose of transferring the steel box girder in a narrow shortcut is achieved.
本申请公开了一种斜拉桥节段钢箱梁分块预制施工方法，通过将标准节段横向分为三块组焊模块进行制作，制作临时匹配件，并在预拼场搭设胎架；然后依次吊放三个组焊模块，将三个组焊模块横向摆放在胎架并对齐，以完成一组待拼装标准节段就位步骤；循环进行待拼装标准节段就位步骤，然后利用临时匹配件将三块组焊模块匹配成标准节段，将多个标准节段匹配成钢箱梁组合段；接着解除临时匹配件连接，留下胎架最后端的一组标准节段，利用运梁车将剩余组焊模块逐一转运至下一施工区域，并将胎架最后端的一组标准节段挪着胎架前端；最终重复所述S2和所述S3，完成钢箱梁分块预制施工。本申请实现了在狭小便道中钢箱梁的转运目的的。
