Sound Absorption Block

• The Track Sound Absorption Block, ‘Field of Technical Art’, written on the claim.
• Technical Substance the Invention Tries to Slove
  • The invention has its purpose to provide the track sound absorption block that reliably absorbs the vicious noise from the vehicle itself and friction between wheel and rail through integrating recyclable rubber from wasted tire, gravel, or hard slag which has excellent ability on buffer and sound absorption with the railroad or the substructure of rail on the subway section.
• Substance of Solution from the Invention
  • The invention is being installed on the both sides of track which creates fixed storage space inside. Sound absorption material storage box is formed with many drainage holes on the bottom; is inherent in the above sound absorption material storage box, and is a sound absorbing material which absorbs the noise transferred from the track with fixed size gap; is a supporting method to attach it to the roadbed while equipped on the bottom of above sound absorbing material storage box; is being installed on the substructure of rail on above track; as well as it provides the track absorption block covering the sleeper sound absorption method to absorb the vibration transferred to it while installed on the outside of sleeper which supports above track.
• Major Use of the Invention
  • The invention is being installed on the bottom of roadbed to reduce noise and vibration transferred from upper structure.

Vibration Absorber

• The invention is in regard to the track vibration absorber which Increases the vibration absorption and minimizes the track destruction through absorbing the impact load from each direction effectively by installation of sleeper and roadbed concrete facility in unfixed way while using the existing sleeper and roadbed concrete facility. It is being inserted between the inside bottom of vibration absorber box equipped on the roadbed concrete and bottom of sleeper box, it is formed with elastic material, and it is the first load absorption method which is being transformed through absorbing the vertical directional load transferred from the sleeper block; it is being inserted between top of the sleeper block and bottom of the rail, it is formed with elastic material, and it is the second load absorption method which is being transformed through absorbing the vertical directional load transferred from the rail; it is being inserted between both ends of horizontal extension part on the substructure of rail and each clip holder, it is formed with elastic material, and it is the third load absorption method which is being transformed through absorbing the horizontal load transferred from the rail; The bottom of one side is attached with the top of above sleeper block, and the bottom of block is combined with the above clip holder to pressurize the top of horizontal extension of rail for supporting the rail; It is a rail supporting method and formed with elastic material to displace the rail to vertical and horizontal directions from the vertical and horizontal directional load of railroading; as well as it provides the track vibration absorber including combination method to combine above rail supporting method with the clip holder, and it is used for reducing vibration and noise from the track.
