Bridge fabrication machine transverse-moving pushing construction method
The invention provides a bridge fabrication machine transverse-moving pushing construction method. The transverse-moving pushing is used for achieving transverse-moving steering from a linear precastbeam to an adjacent curve precast beam in the precast beam erecting process, and a bridge fabrication machine comprises a main body, a forward-moving device and a supporting device used for supportingthe main body. The forward-moving device comprises a front fulcrum trolley and a rear fulcrum trolley. The supporting device comprises a front supporting leg, a middle supporting leg and a rear supporting leg. The construction method comprises the steps of S1), after a section of linear precast beam is erected, moving the bridge fabrication machine to the junction position of the erected linear precast beam and an adjacent to-be-erected curved precast beam; S2) arranging a sliding assembly for reducing sliding friction between the bridge fabrication machine and the supporting device between the bridge fabrication machine and the supporting device; S3) applying a moment to the bridge fabrication machine to enable the bridge fabrication machine to horizontally deflect towards the adjacent to-be-erected curved precast beam by a preset angle; and S4) withdrawing the sliding assembly, and fixing the bridge fabrication machine with the supporting device.
本发明提供了造桥机横移顶推施工方法，横移顶推用于在预制梁架设过程中实现直线预制梁到相邻的曲线预制梁的横移转向，造桥机包括：主体、前移装置和用于支撑主体的支撑装置；前移装置包括：前支点小车和后支点小车；支撑装置包括：前支腿、中支腿以及后支腿；施工方法包括：S1)在完成一段直线预制梁架设之后，将造桥机移动至已架设的直线预制梁与相邻的待架设的曲线预制梁的交界位置；S2)在造桥机与支撑装置之间设置用于减小造桥机与支撑装置之间滑动摩擦的滑移组件；S3)对造桥机施加力矩，使得造桥机朝向相邻的待架设的曲线预制梁水平偏转预定角度；S4)撤出滑移组件，将造桥机与支撑装置固定。
