Cast-in-place beam support structure crossing channel and existing bridge and construction method
The invention discloses a cast-in-place beam support structure crossing a channel and an existing bridge and a construction method, and relates to the technical field of bridge construction. The bracket structure is arranged on the steel pipe pile close to the existing bridge; the bracket structure inclines towards the existing bridge in the transverse bridge direction, and the supporting area of the inclined bracket structure accounts for more than half of the projection overlapping area of the existing bridge and the cast-in-place beam. The steel pipe short columns are vertically arranged on the top face of the existing bridge, and the top ends of the steel pipe short columns, the bracket structures and the steel pipe piles are flush; the bailey beam is broken in the transverse bridge direction, most of the bailey beam is borne at the top ends of the steel pipe piles and the bracket structures, and a small part of the bailey beam is borne at the top ends of the steel pipe short columns. According to the cast-in-place beam support structure and the construction method, the technical problem that in the prior art, drilling and piling greatly damage an existing bridge is solved.
本申请公开了一种跨渠跨既有桥梁的现浇梁支架结构及施工方法，涉及桥梁施工技术领域，包括：若干插打于既有渠内的钢管桩；牛腿结构，其设置于临近既有桥梁的钢管桩；所述牛腿结构沿横桥向朝既有桥梁倾斜，且倾斜后的牛腿结构支撑面积占既有桥梁和现浇梁的投影重叠区的一半以上；若干垂直设置于既有桥梁顶面的钢管短柱，所述钢管短柱、牛腿结构和钢管桩的顶端平齐；贝雷梁，其从横桥向断开，其大部分承载于钢管桩和牛腿结构的顶端，其小部分承载于钢管短柱的顶端。本申请的现浇梁支架结构及施工方法，解决现有技术钻孔打桩对既有桥梁伤害大的技术问题。
