From 1997 to 2007,China implemented six times the range of existing line speed , greatly changed the face of railway transportation .E xpand petitiveness of the railway transportation in transportation market . It has achieved great economic and social benefit. The sixth railway speed railway will no longer speed, China Railway will focus on the construction of high-speed passenger dedicated line, which reached a maximum speed of three hundred and fifty kilometers per hour. To achieve this goal, and ensure the safety of train operation, on the railway line, must be kept in good condition, it is to the railway line in accordance with the provisions of the plan, including bridges and tunnels, repair and maintenance of regular, this work is maintenance work. Among them, a tension bolt is an important project of railway department. The main task of railway line maintenance is elastic fastening bolts, bolts and bolt oiling. The main line of the fastener is connected into the rail and sleeper frame structure, to resist the rail and sleeper in the horizontal plane between the rotation and the rail and rail movement, so as to ensure that the frame structure of the whole Sichuan .
