架桥施工时,传统现浇或整孔架设的施工方法都对地面(水上)交通造成不同程度的影响,需征用较多的施工用地。而节段拼装法施工不仅可节省施工用地,甚至可做到桥上的架设施工不影响桥下的交通。另外,由于节段箱梁工厂化预制,质量易于保证,外形设计优美,节段长度和重量可根据运输起吊设备灵活划分,拼装速度较快。可以说,节段拼装法是未来城市高架桥施工的发展方向。 During bridge construction, the construction methods of traditional cast-in-place or erected all have different degrees of impact on the ground (water) traffic, and more construction land will be requisitioned. The segment assembly method construction can not only save construction land, and even can do erection of the bridge construction does not affect the traffic under the bridge. In addition, due to the prefabricated box girder factory, easy to ensure the quality assurance, beautiful shape design, length and weight of the segment can be flexibly divided according to the transport lifting equipment, assembled faster. It can be said that the segment assembly method is the future direction of urban viaduct construction.
