Example Embodiment
[0028] Example 1
[0029] For the track of the present invention, see figure 1 , It includes the track body, which is composed of the rail head 11, the rail waist 12 and the rail bottom 13. A layer of solid high damping is provided on the non-working outer surface of the rail body except the rail head top surface 111 and the side working surface 112 Material 21. The solid high damping material is specifically based on the high damping modified asphalt that is solid at room temperature, and the high damping material made of rubber powder, talc powder, mica powder, etc. is added, and a layer of high-strength fiber mesh is inserted in the middle to make a damping coil. , Hereinafter referred to as modified asphalt damping coil. The solid high damping material is a viscoelastic solid at room temperature, and becomes a viscous liquid after heating, and can be integrated with the track body by means of self-adhesive, hot-melt bonding or thermal coating.
[0030] For the track with this...
Example Embodiment
[0031] Example 2
[0032] See figure 2 , On the surface of the constraining structure 3, usually a rigid aluminum plate or color steel plate, bent or rolled into a profile with a cross section similar to the rail waist 12, rail jaw 114 and rail bottom 131, or engineering plastic extrusion Two layers of solid high damping material 21 are hot-melt bonded to the profile, that is, the constraining plate, and the modified bitumen damping coil is still made into a damping structure, and then the rail waist 12, rail jaw 114 and The upper surface 131 of the rail bottom is directly thermally fused to the rail body.
Example Embodiment
[0033] Example 3
[0034] See image 3 The difference from Example 2 is that the high damping material is two layers of high damping rubber, which is vulcanized with the restraining plate in the factory to form a damping structure, which is tightly pressed by the clamps 6 arranged on both sides of the rail waist 12 On both sides of the track body. The clamping member 6 is a C-shaped clamp around the bottom of the rail between the rail sleepers, and it can also be an extension of the rail fastener elastic strip toward the rail waist, or a bolt penetrating the rail waist.
[0035] Embodiments 1-3 can be implemented in factory production or on-site, but Embodiment 3 is relatively more suitable for rapid on-site implementation. If it is produced in a factory, the restraint plate and the track body are directly vulcanized into one body with high-damping rubber, without clamping parts, and the vibration damping effect is better.
