Body noise reducing railway track bed - has flexible support pads accessible through entry holes with concrete covers

摘要

The body noise damping railway track bed is used in tunnels or on bridges. The noise damping arrangement pads are readily inserted and removed. The track support plates (3) are placed by means of flexible pads (4) on the tunnel floor (2) or on a bridge. The track support plates have between rails (5) entry openings of rectangular or round shape with conical seat. The entry openings are provided optionally with a concrete cover plate (8) or with a concrete trough filled with a noise damping material. The concrete cover can have water draining channels (11) and enclosing circumferential flexible rims (7) are used as a protection for the edges.
