摘要
随着国家交通行业基础设施的不断发展,立体交叉的线路工程日益增多。本文结合吉林市哈达湾地下综合管廊下穿既有铁路,在不中断铁路行车的情况下,采用D型施工便梁加固既有线路,顺利完成了施工任务,确保了铁路运营安全,同时总结了相关经验,以期可为后续同类工程的施工提供参考。
With the continuous development of national transportation infrastructure,the number of three-dimensional crossing line projects is increasing.In this article,combining with the utility tunnel underpassing the existing railway of Hadawanin in Jilin city,under the condition of not interrupting the running of the railway,the existing railway is reinforced by adopting the D-type construction beam,which successfully completes the construction task and ensures the safety of the railway operation.The relevant experiences are summarized,which can provide references for similar projects.
