摘要
结合石长铁路增建第二线工程曹河立交桥,介绍下穿站内多股道以及在道岔区顶进施工中,对既有线多股道及道岔的架空加固防护、对地下管线及信号机的防护措施,以及如何利用D型便梁纵梁及工字钢横梁组合抬梁法施工,在满足对既有线路架空加固施工的前提下达到对转撤机的防护。
Combined with the project of the second added line of Cao River overpass of Shimen North-Laodao River Railway, this paper introduced the protective measures during the jacking construction of underpassing multistrand and turnout area, such as aerial reinforcement protection for the multistrand existing railway and turnout,protection for underground line and signal machine,and how to use the method of combination D-shaped longitudinal beam with I-beam to achieve the purpose of protection against switch machine on the basis of satisfying the construction of aerial reinforcement for the existing railway.
