Urban viaduct main line diversion and confluence widening section combination structure
The invention discloses an urban viaduct main line diverging and converging widening section combined structure which comprises a normal bridge section and a widening bridge section which are located on the two sides of a main line road center line respectively. The combined structure comprises a linear end cross beam, a middle cross beam, a steel-concrete combined small box girder and a broken line type end cross beam which are arranged in the extending direction of the center line of the main road, wherein the middle cross beam and the steel-concrete combined small box girder are arranged between the linear end cross beam and the broken line type end cross beam at intervals. The steel box girder is pulled and the concrete bridge deck slab is pressed at the same time, so that the span of the main line flow dividing and converging widening section is further increased, the widening and slope changing adaptability of the main line flow dividing and converging section is improved, and the end cross beam prestress setting and slab staggering phenomena are avoided; the steel box girder is rapid in construction, short in period and small in influence on surrounding traffic and environment.
本发明公开了一种城市高架桥主线分合流变宽区段组合结构，其中城市高架桥主线分合流变宽区段包括分别位于主线道路中心线两侧的正常桥段和变宽桥段，本组合结构包括沿主线道路中心线延伸方向布置的直线型端横梁、中间横梁、钢混组合小箱梁和折线型端横梁，中间横梁和钢混组合小箱梁间隔布置于直线型端横梁和折线型端横梁之间。本发明同时利用钢箱梁受拉和混凝土桥面板受压，进一步增加了主线分合流变宽段的跨径，提高了主线分合流段变宽、变坡的适应性，从而避免了端横梁预应力的设置和错台现象；钢箱梁施工快捷，周期短，对周围交通、环境的影响较小。
