The railway vehicle is used for repairing the faults in current railway subgrade face. It can be used for gravel track spacing, wired or 4 m and more than double track or line of the assignments section of roadbed surface,it can finish the following procedure in one flow path:digging the old ballast in the upper of the roadbed, and bring them to metal seperation and recycling; Mixed sand material and control its water content; digging the rest trackbed and roadbed upper; Flat top subgrade; Laying the corresponding protection object, such as geotextile, polystyrene plate and so on; laying sand mixed material and solidified so that to form protective layer of roadbed surface.
