Abstract:

 In order to increase the running speed of the trains and to strengthen the competibility of the railway transportation system, the level railway crossing junctions are required to be converted into grade junctions. Therefore, jacking of frameshaped culverts is needed so as to avoid the interruptions of the railway system. This paper introduces the technology for the reinforcement of the existing railways, as well as the construction methods, technical measures, deviation prevention methods and deviation correction methods taken during the jacking of the largespan obliquecrossing frameshaped culvert.

Key words: frameshaped culvert, jacking  technology
