Overpass existing line large-span large-section steel box girder and construction method
The invention relates to an overpass existing line large-span large-section steel box girder and a construction method, a steel box girder in-place guide device is adopted, a to-be-in-place steel box girder section is dragged and guided by the in-place steel box girder section, the operation difficulty of temporary in-place operation of the steel box girder is reduced, and the construction efficiency is improved. The workload of subsequent adjustment of the horizontal position of the steel box girder is reduced, so that the construction efficiency is improved; a steel box girder accurate beam falling in-position device is adopted, and the horizontal position of a steel box girder section position is adjusted through a horizontal jack; by the adoption of the steel box girder elevation fine adjustment device, after the steel box girder segments are jacked to the elevation by the jack with the sleeve, the wedge-shaped sets and the tensioning stand columns are used for jacking, and the steel box girder elevation adjustment precision is improved through a plurality of pieces of adjustment equipment.
本发明涉及一种上跨既有线大跨径大断面钢箱梁及施工方法，采用了钢箱梁就位导向装置，利用已就位的钢箱梁节段对待就位的钢箱梁节段进行牵引导向，降低了钢箱梁临时就位操作的操作难度，减少了后续钢箱梁水平位置调整的工作量，进而提高了施工效率；采用了钢箱梁精确落梁就位装置，通过水平千斤顶调整钢箱梁节段落位的水平位置；采用了钢箱梁标高精调装置，带套筒千斤顶顶升钢箱梁节段至标高后，用楔形组和张紧立柱顶住，通过多个调节设备，提高了钢箱梁标高调整的精度。
