The difference between the whole sound barrier of the bridge and the sound barrier of the board
Talking about the technical requirements of sound barrier and integral board
Sound barrier in the technical aspects of a lot of requirements, in order to ensure the acoustic barrier acoustic performance to ensure that the structure is safe and durable. The following is a small series for the Green Hill for everyone to talk about the railway sound barrier overall and plug-type technical requirements.
Sound barrier technical requirements
(1) The sound barrier must be set to meet the railway operating safety requirements and meet the needs of railway facilities for maintenance and repair.
(2) Barrier spacing of sound barrier: 2.0m.
(3) sound barrier components should be simple, standardized, easy to install and maintenance of construction and maintenance.
(4) Under normal conditions of use, the main structure of the sound barrier design life of 50 years, the life of sound-absorbing material for 25 years, and should have easy to replace the sound-absorbing material conditions.
(5) All exposed and concealed steel components, fittings, angle steel, etc. must be hot-dip galvanized, the corrosion resistance of metal parts should not be less than 15 years.
(6) sound barrier should be in accordance with the relevant provisions of the grounding design.
(7) Materials and materials, the connection between the unit plate and the unit plate, the cell plate and the column, the unit plate and the foundation shall be the corresponding structural measures to resist the telescopic deformation, avoid the noise leakage and the secondary structure noise.
