Drilling Holes on the Rail


Different aperture corresponding to different positions:

A. Section air choke and yard choke rail will be used with Φ 13mm drilling bit.

B. Drilling bit with Φ 9.8mm will be used for interval Capacitance and Station Capacitance Rail drilling.

C. Double body protection box rail drilling with Φ 13.2 bit. If not, butter is applied to the hole to prevent rust; if German plug is used, use a professional casing tool to push it into the plug.

D. The connection of double body box and choke adjacent equipment is fixed on the sleeper with a 10 chemical anchor bolt and "M" card. The relationship between the rail connection and the direction of the train operation should be considered when the rail anchor bolts are fixed, and the long line is required to be installed on the back of the sleepers in the direction of the train running.


In the case of sleeper board joints, transponders and rail welds, the compensation capacitor mounting position shall be 0.65 m from the sleeper board joint or transponder center, and all rail drilling (hole center) shall be 0.45 m from the rail weld line.

The piercing position of the connecting line of the same equipment on the two rails shall be maintained at the same coordinates. The distance between the two adjacent eyes is 80 mm when using double wire connection.
