Construction method for erecting a beam of a road-rail integrated double-layer viaduct with full precast beams
The invention relates to a construction method for erecting a beam of a road-rail integrated double-layer viaduct with full precast beams, which is suitable for Y-shaped piers or H-shaped piers with closed frame-shaped piers of the double-layer integrated viaduct, and is characterized in that precast beams are adopted as an upper-layer beam body and a lower-layer beam body; the upper-layer precastbeam and the lower-layer precast beam are conveyed to an erecting point from a beam lifting point in an on-beam beam conveying mode and share one set of bridge erecting machine frame beam. In the same span, the lower-layer beam is erected firstly, then the upper-layer beam is erected, overall arrangement is conducted, the construction period and cost are optimized, and the construction speed is increased.
本发明为一种全预制梁的公轨一体化双层高架桥架梁施工方法，适用于双层一体化高架桥的桥墩为闭口框架型的Y形墩或H形墩，其特征是上层、下层梁体均采用预制梁，上层预制梁和下层预制梁分别采用梁上运梁的方式从提梁点运送至架设点，上层预制梁和下层预制梁共用一套架桥机架梁。同一跨内，先架下层梁，再架上层梁，统筹安排，实现工期及费用的最优化，加快施工速度。
