目前,我国中长期铁路网规划正在推进实施,9条客运专线及京沪高速铁路陆续开工建设。随着铁路建设高潮的到来,无碴轨道工程的建设迅速展开,无碴轨道施工机械的研制也随之全面展开。无碴轨道是一种新型的轨道结构,它既具有足够的强度,又有一定的弹性,残余变形的积累甚小,轨道结构 At present, China’s medium and long-term railway network planning is being implemented, nine passenger lines and the Beijing-Shanghai high-speed railway started construction. With the advent of the railway construction climax, the construction of ballastless track project started rapidly, and the development of ballastless track construction machinery also started in full swing. Ballastless track is a new type of track structure, which not only has sufficient strength, but also has some elasticity, the accumulation of residual deformation is very small, orbital structure
