Cross-line erecting method for crossing multi-pier and multi-line beam
The invention discloses a cross-line erecting method for crossing multiple piers and multiple line beams. The method comprises the steps that a first side line beam falls on a moving and transporting device through a bridge girder erection machine; a telescopic oil cylinder is used for moving the first side boundary beam to the position above the first side boundary pier through a rail; the first side boundary beam is jacked upwards by 2-3 cm through an oil jack; the moving and transporting device and the telescopic oil cylinder are moved to the position above the main line pier, and the rail above the first side line pier is dismantled; the first side boundary beam is descended through retraction of the oil jack, support grouting is started, and erection of the first side boundary beam is completed; and then erecting the other side line beam, and finally completing the erection of the main line box beam. The main line bridge girder erection machine is used for moving girders of other lines across holes, then the girders fall to the position above the moving and transporting device, and the box girders are transported to the designated line through the moving and transporting device for girder body erection. The moving and transporting device is low in manufacturing cost and convenient to construct, and the construction period and the construction cost can be greatly saved. The moving and transporting device is low in manufacturing cost and convenient to construct, and the construction period and the construction cost can be greatly saved.
本发明公开了一种跨多墩多线梁的跨线架设方法，包括利用架桥机将第一边线梁落在移运器上；使用伸缩油缸将第一边线梁通过轨道移至第一边线桥墩上方；利用油顶将第一边线梁向上顶起2‑3cm；将移运器及伸缩油缸移至主线桥墩上方，拆除第一边线桥墩上方轨道；利用油顶的回缩降落第一边线梁，开始进行支座灌浆，完成第一边线梁架设；再进行另一边线梁架设，最后完成主线箱梁架设即可；本发明利用主线架桥机将其余线路的梁移跨过孔后，下落至移运装置上方，由移运装置将箱梁运输到指定线路进行梁体的架设。该移运装置造价低，施工方便，能极大的节约施工工期和施工成本。该移运装置造价低，施工方便，能极大的节约施工工期和施工成本。
