<p>PURPOSE: To provide a laying structure of cable for railway which can carry out tamping work with a tamping machine over the full length of a cable without damaging the cable protective material of the cable nor cutting the cable. CONSTITUTION: Ballast 4 tamping work with an automatic ballast tamping machine can be carried out over the full length of a cable 9 without damaging the cable protective material 6 of the cable 9 nor cutting the cable 9, because the cable protective material 6 surrounding the cable 9 is buried in the roadbed, of a railway. Therefore, the rationalization of the tamping work can be facilitated, because the ballast tamping work can be carried out over the full length of the cable 9 by using the automatic tamping machine.</p> |
