Problems solved by technology

[0004] During the assembly process of sound-absorbing panels, sound-absorbing materials and sound-insulating panels, adhesives or screws are usually used to connect them. The bonding fastness of adhesives is not enough. It will be loose between them, which will affect the sound absorption effect. It is more troublesome to use screws to connect, and the screws are easy to rust and oxidize, and they will loosen later.
[0005] In addition, the currently commonly used sound-absorbing materials include metal, cement-based, and glass fiber r

Abstract

The invention relates to a road surface supporting facility, in particular to a cement-based non-metal sound barrier unit plate. The unit plate comprises a sound absorption plate, a sound insulation plate and a sound absorption material arranged between the sound absorption plate and the sound insulation plate; the sound absorption plate is provided with a pipeline, the interior of the pipeline is hollow, and the sound insulation plate is provided with a convex block of which the shape is matched with that of the interior of the pipeline. When assembling is performed, the convex block on the sound insulation plate is directly inserted into the pipeline arranged on the sound absorption plate, the sound absorption material is clamped between the sound absorption plate and the sound insulation plate, tediousness of traditional screw fixing is omitted, better convenience, rapidness and firmness are achieved, and the loosing risk generated by using a binding agent or the screw is avoided.

Description

technical field [0001] The invention relates to a pavement supporting facility, in particular to a cement-based non-metal sound barrier unit board. Background technique [0002] During the operation of high-speed railways, road vehicles or equipment, a lot of noise will be generated, which will disturb the residents, schools and office areas along the road and nearby. At present, sound barriers are mainly used to block the transmission of noise, so as to achieve the purpose of preventing noise pollution. [0003] The traditional sound barrier unit board is composed of a sound-absorbing board, a sound-absorbing material and a sound-insulating board. The sound-absorbing material is set in the cavity formed between the sound-absorbing board and the sound-insulating board, and sound waves enter through the sound-absorbing holes on the sound-absorbing board. Sound-absorbing material, the sound wave can go deep into the material along the gap of the sound-absorbing material, fric...
