Method for assembling arch rib sections of large-span multi-pipe butt-joint arch bridge
The invention discloses a method for assembling arch rib sections of a large-span multi-pipe butt-joint arch bridge. A construction zoning step: arranging a single-truss splicing area, a double-truss splicing area and a segment splicing area on a construction site, and respectively arranging a single-splicing jig frame, a double-splicing jig frame and a segment jig frame in the single-truss splicing area, the double-truss splicing area and the segment splicing area; a single truss piece splicing step: in the single truss piece splicing area, splicing at least two parallel main chord pipes and a plurality of first connecting pieces between two adjacent main chord pipes to form a single truss piece; in the double-truss-piece assembling area, the two parallel single truss pieces and the multiple second connecting pieces between the two single truss pieces are assembled to form the double truss pieces; and a section splicing step: in the section splicing area, splicing the two parallel double-truss pieces and the plurality of third connecting pieces between the two double-truss pieces to form an arch rib section. According to the method for assembling the arch rib sections, the assembling efficiency of the arch rib sections of the large-span multi-pipe butt-joint arch bridge can be improved, and the construction period is effectively shortened.
本发明公开了一种大跨径多管对接拱桥的拱肋节段拼装方法，包括；施工分区步骤：在施工现场设置单桁片拼装区、双桁片拼装区及节段拼装区，并在单桁片拼装区、双桁片拼装区及节段拼装区分别布置单拼胎架、双拼胎架及节段胎架；单桁片拼装步骤：在单桁片拼装区，将至少两个并列的主弦管及相邻两个主弦管之间的多个第一连接件拼装形成单桁片；双桁片拼装步骤：在双桁片拼装区，将两个并列的单桁片及两个单桁片之间的多个第二连接件拼装形成双桁片；节段拼装步骤：在节段拼装区，将并列的两个双桁片及两个双桁片之间的多个第三连接件拼装形成拱肋节段。本发明提供的拱肋节段拼装方法，能够提高大跨径多管对接拱桥的拱肋节段的拼装效率，有效缩短工期。
