摘要
城市发展促进轨道交通快速发展,地铁作为解决日益恶化的城市交通主要途径之一,车站多设置在交通拥堵及商业繁华路段,这些地区施工区附近多为交通要道,地下密集分布着多条市政管线,并且距离周边建筑物距离较近,总体施工难度较大。以苏站轨道交通6号线苏站东路站为例,在路口处采用顺做法和逆作法相结合先施工部分顶板,然后恢复道路通行,继续施工车站其余结构。这种施工方法一方面可以减少对地面交通的影响;另一方面可以将管线集中布置减少管线迁改次数。
The development of city facilitates rapid development of railway transportation.As a major method to solve increasingly deteriorating urban traffic,stations are normally set at the spots of congestion and commercial hubs,whose construction zones are among main arteries.Moreover,underground municipal pipelines are densely scattered there,with a close distance to surrounding buildings,causing difficulty for construction.Taking Donglu Station on the Sixth Railway of the Suzhou Station railway transportation as an example,we can combine cut-cover method and top-down construction method at the junction so as to construct sectional roof and later resume the traffic.Sequentially,the rest construction of the station goes on.For one thing,this method can help reduce impacts on the surface transportation;for another,it makes the concentrated layout of pipelines possible and might decrease modifications of pipelines accordingly.
