Railway inserting plate type super-high strength concrete-micro-porous ceramic compound sound barrier unit plate
The invention discloses a railway inserting plate type super-high strength concrete-micro-porous ceramic compound sound barrier unit plate. The sound barrier unit plate is composed of two rib plates on the periphery, a back plate fixed on the back portions of the rib plates and a micro-porous ceramic sound-absorbing plate fixed between the rib plates; the back plate and the rib plates are prefabricated and combined through reactive powder concrete to form a dovetail-groove-shaped cavity, and the upper end and the lower end of the sound-absorbing plate are each provided with a first oblique plane matched with the dovetail-groove-shaped cavity; the sound-absorbing plate is embedded in the dovetail-groove-shaped cavity to form an embedded fixing structure, and a hollow cavity is formed between the back plate and the sound-absorbing plate. The sound barrier unit plate adopts the reactive powder concrete with super strength, the sound-absorbing plate adopts a micro-porous ceramic body, the sound-absorbing plate is installed by applying structural modes such as embedding and fixing in the stress structure, therefore, the unit plate has better weather resistance, the construction is more reasonable and stable, materials are more environment-friendly, the effects of sound absorbing and noise reducing are obvious, and the maintenance is more convenient and safer in operation.
