Abstract
A ground-borne noise and vibration damping system in which is a track bed formed with rails for a railway vehicle and generating noise and vibration, a structure is to be protected against the noise and vibration; and a damper for ground-borne noise and vibration is embedded vertically in the ground and interposed between the track bed and the structure. The damper has two upright rigid concrete plates defining a vertical gap between them, and an elastic mat sandwiched between the concrete plates and in contact therewith.
Claims6
A ground-borne noise and vibration damping system comprising:
- a track bed formed with rails for a railway vehicle and generating noise and vibration;
- a structure to be protected against said noise and vibration;
- and
- a damper for ground-borne noise and vibration embedded vertically in the ground and interposed between said track bed and said structure, said damper comprising:
- two upright rigid concrete plates defining a vertical gap between them, and
- a rubber mat sandwiched between said concrete plates and in contact therewith, said concrete plates extending substantially to the surface of the ground in which said damper is embedded, a textile layer being inlaid in said mat.
A ground-borne noise and vibration damping system comprising:
- a track bed formed with rails for a railway vehicle and generating noise and vibration;
- a structure to be protected against said noise and vibration;
- a damper for ground-borne noise and vibration embedded vertically in the ground and interposed between said track bed and said structure, said damper comprising:
- two upright rigid concrete plates defining a vertical gap between them, and
- an elastic mat sandwiched between said concrete plates and in contact therewith;
- and
- a channel formed along an edge of one of said plates opening toward the other of said plates, and a contoured gasket received in said channel and bridging said gap.
The ground-borne noise and vibration damping system comprising:
- a track bed formed with rails and a rail support;
- and
- a damper for ground-borne noise and vibration beneath said bed and comprising:
- a lower concrete plate having an upwardly-extending portion outwardly of said bed,
- a tub-shaped elastic mat lining said lower concrete plate, and
- an upper concrete plate cast in situ on said mat and supporting said bed, said concrete plates sandwiching said mat between them.
