摘要
随着公路工程规模大、线路长的特点日益突出,以及国家在临时用地管控上日益严格,对项目钢栈桥设计与施工的要求也越来越高。在通航河流上施工,需要考虑栈桥施工过程及完工后的航道通行保障及安全。文章以264省道淮安区段建设工程苏北灌溉总渠栈桥为例,分析在通航河流上钢栈桥的设计与施工问题,为同类型工程提供借鉴。
With the increasing scale of the existing highway project,the characteristics of the long route,and the increasingly stringent national measures on temporary land management and control,the requirements for the design and construction of the steel trestle of the project are becoming increasingly urgent.It is also necessary to consider the channel traffic guarantee and safety during and after the trestle construction.This paper discusses the design and construction of steel trestle on navigable rivers by borrowing from the construction project of the trestle of the North Jiangsu Irrigation Canal in Huai'an section of Provincial Highway 264,to provide some experience for other engineers and technicians in similar projects.
