Description
Technical field
The utility model relates to a kind of noise barrier, specifically is meant a kind of light-duty sound absorbing-insulating barrier.
Background technology
Traffic noise is a urban traffic in the process that modernized directions such as high-grade, high-speed, overhead solid develop, motor vehicle quantity sharply increase bring make the serious day by day noise pollution of urban highway traffic noise pollution.The reason that the traffic noise pollution problem produces; Mainly contain two aspects: the one, the traffic above-ground facility has existed or existing planning; Build noise-sensitive structures such as school, hospital, dwelling house in its adjacent domain; Because programming and distribution are unreasonable, reserve necessary antinoise distance, the traffic noise pollution problem appears after causing noise-sensitive structure to come into operation: the 2nd, because the construction of traffic above-ground facility or the pollution from environmental noise that operation causes.Except that newly-built traffic above-ground facility may produce the pollution from environmental noise, some traffic above-ground facilities put the back into operation along with the increase of vehicle flowrate, or the change of operational factor (like railway speed increase), also possibly produce new noise pollution problem.Road traffic noise has the advantages that intensity is big, influence basin is wide, becomes the primary pollution source of urban environment noise gradually, also becomes the difficult point of environmental noise control.The development of noise barrier is exactly the influence for transport solution noise on human life and work; Control from the source of noise and route of transmission and abate the noise, noise barrier refers to alleviating the driving noise near resident influence is arranged on the other wall formula structure of roadside.But there are problems such as structure is single, weight big, installation inconvenience in present noise barrier, develops the trend that noise barrier in light weight, easy for installation is the industry.
