Construction method of river-crossing bridge
The invention discloses a construction method of a river-crossing bridge, which comprises the following steps: respectively splicing one part of river channel box girders on river banks on two sides of the outer side of the bridge in the length direction of the bridge, oppositely moving the spliced river channel box girders to realize closure to form a complete river channel box girder, transversely moving the complete river channel box girder to the in-situ position of the bridge, and constructing the river-crossing bridge. And the river channel box girder is lifted to the required height through the lifting device so as to be closed with the side span part, so that a complete bridge structure is formed. According to the construction method, rapid construction of the river-crossing bridge can be achieved for some water source protection areas or navigable rivers with small spans and limited peripheral construction sites, water source pollution or river traffic blocking can be avoided in the construction process, and the construction cost is relatively low.
本发明公开了一种跨河桥梁的施工方法，通过在桥梁原位外侧的两侧河岸沿桥梁长度方向各拼装河道箱梁的其中一部分，将拼装好的河道箱梁相向移动实现合龙构成完整的河道箱梁，将完整的河道箱梁横向移动至桥梁原位处，通过起吊装置将河道箱梁提升至所需高度以实现与边跨部分的合龙，从而形成完整的桥梁结构。本发明的施工方法对于一些跨度相对较小、且周边施工场地有限的的水源保护地或者通航河道，可以实现跨河桥梁的快速施工，施工过程中可以避免污染水源或者阻断河道交通，而且施工成本相对较低。
