Prefabricated erection construction process for small-curve box girder crossing existing railway yard
The invention relates to the technical field of small-curve box girder construction, in particular to a prefabricated erection construction process for a small-curve box girder crossing an existing railway yard. The method comprises the following steps: 1, prefabricating a box girder: (1) manufacturing a girder pedestal; (2) customizing a box girder template; 2, box girder erection (1), cross-railway box girder erection (2), bridge deck widening and temporary buttress erection at a curve; 3, bridge deck system rapid construction: (1) wet joint construction and (2) outer side anti-collision wall construction; and 4, long-distance and large-component box girder transportation. According to the method, the problems that the prefabricated box girders are large in difference, oversized box girder cross-railway key point construction is slow, curve oversized box girder erection is slow and bridge deck system construction is slow are solved, the construction process has replicability and generalization performance, good application and popularization prospects are achieved, and reliable decision basis and technical guidance are provided for future planning and construction of the type.
本发明涉及小曲线箱梁施工技术领域，特别涉及小曲线箱梁跨既有铁路站场预制架设施工工艺。一、箱梁预制(1)制梁台座制作(2)箱梁模板定制；二、箱梁架设(1)跨铁路箱梁架设(2)桥面变宽和曲线处临时支墩搭设；三、桥面系快速施工(1)湿接缝施工(2)外侧防撞墙施工；四、长距离、大构件箱梁运输。本发明解决了预制箱梁差异大、超大箱梁跨铁路要点施工、曲线超大箱梁架设以及桥面系施工慢的问题，施工工艺具有可复制性和推广性，具有很好的推广应用前景，为以后的该类规划建设提供了可靠的决策依据和技术指导。
