Quality Control of the Ballastless Track Box Beam Surface Flatness of Passenger Dedicated Line CRTS II Plate

The beam surface of passenger dedicated line CR-TS-II plate flatness inspection requirements higher, this paper introduces specific control measures and construction method of the I standard box beam surface flatness control in Jiangxi Shanghai Kunming passenger dedicated line segment in produ-ced by Yushan beam field. In order to meet the beam surface acceptance of 3 mm/4 m, 2 mm/1 m, beam field in the process, vibration level of equipment made the reform and innovation, to reduce the amount of later deck polishing, and save cost.
