既有单股道铁路硬架空方案设计与施工
|
摘要
在我国城镇化进程中,道路发展速度很快,就会不可避免引起道路和城市既有铁路的交叉设计越来越多。其中下穿既有铁路的交叉设计应用较广泛。在设计以及既有单股道铁路硬架空施工中,进行新技术的利用,在设计中遵循图纸严格进行设计,并在施工中进行实施,就可以使建设水平得到提高,有利于既有铁路硬架空下道路箱桥的完工。结合具体的工程实例进行方案设计并对既有单股道铁路硬架空施工进行了研究。
In the process of urbanization in China,the rapid development of roads will inevitably lead to more and more cross-design between roads and existing railways in cities. The cross design of the existing railway is widely used. In the design and in the hard overhead construction of the existing single-track railway,the construction level can be improved by utilizing the new technology,strictly following the drawings in the design,and carrying out the design in the construction. It is advantageous to the completion of the box bridge of the existing railway. In this paper,the project design and the hard overhead construction of the existing single track railway are studied in combination with concrete engineering examples.
