摘要
近年来,在既有站场改造施工中,有关既有线下穿铁路框架涵接长施工常用方法为:封停既有线现浇施工。这种方法封闭既有线时间长,对铁路运输影响较大,一般适用于运输量较小或对铁路运输影响小的区段,因此如何减小既有线下穿铁路框架涵接长施工对既有线运营的影响,已成为施工的一个棘手问题。本方法通过理论设想并成功运用于实际,解决了既有线下穿铁路框架涵接长对运输影响大的问题,既安全、省时,又提高了经济效益和环保效益。
In recent years,in the reconstruction of existing stations and yards,the commonly used method for the lengthening construction of frame culverts under existing lines is to close down the cast-in-situ construction of existing lines.This method of closing existing lines takes a long time and has a significant impact on railway transportation.It is generally applicable to sections with small transportation volume or small impact on railway transportation.Therefore,how to reduce the impact of the construction of existing line undercrossing railway frame culvert extension on the operation of existing lines has become a thorny issue in construction.Through theoretical assumption and successful application in practice,this method solves the problem that the extension of frame culverts under existing railways has a significant impact on transportation,which is safe and time-saving,and improves economic and environmental benefits.
