This absorbent lined barrier concrete structure and functional description as follows: by with clamping block erection column by the clamping of acoustical cotton block live, the fixation of acoustical cotton block is stablized, by sound-absorption hole, the noise that road sends is absorbed, noise is adsorbed by acoustical cotton block, decrease noise, the living environment of the resident around road is improved, this barrier also has sound rebounding mechanism, when position noise is upwards propagated, recoiled in sound-absorption hole by gear soundboard and absorbed by sound-absorbing sponge, further reduce noise, design ingenious, in addition, when meeting rainy weather, by the setting of rainproof film, make rainwater cannot enter in installation cavity by suction hole, maintain the validity of acoustical cotton block, it is thorough that design is considered.
In above-mentioned a kind of double-face sound-absorbing barrier, the both sides bottom described mounting shell are all fixed with the fixed block be square, described fixed block have several screwed holes.
Realize the fixing, easy for installation of mounting shell by fixed block, mechanism installs firmly stable.
In above-mentioned a kind of double-face sound-absorbing barrier, described rainproof film is that transparent nylon material is made.
Transparent nylon material cost is low, practical.
In above-mentioned a kind of double-face sound-absorbing barrier, the quantity of described erection column is 5 and lays respectively at corner place and the center of described installation cavity.
The erection column of this quantity can make that acoustical cotton block is stable to be firmly arranged in installation cavity, prevents from rocking even coming off.
Compared with prior art, this double-face sound-absorbing barrier has the following advantages:
1, the design of this double-face sound-absorbing barrier structure is ingenious, abates the noise effective.
2, the clamping of acoustical cotton block is lived by the erection column with clamping block by this double-face sound-absorbing barrier, and the fixation of acoustical cotton block is stablized.
