Active powder concrete noise barrier

Abstract

The invention discloses an active powder concrete noise barrier which comprises a thin noise absorption board, a composite noise absorption board, a groove body, transparent resin boards and columns. The thin noise absorption board is a thin single-wall board provided with corrugations and holes, the composite noise absorption board is a composite board provided with corrugations, holes and a noise attenuation material, double layers of clamping grooves are formed in the inner side wall of the groove body, the resin boards are embedded and inserted into the clamping grooves and are arranged among the columns in a staggered mode, the inner surfaces of the resin boards are adhered with the man-made luminescent stones, and titanium dioxide material bags are filled among the resin boards. The active powder concrete noise barrier is diversified in function and high in ecological value, achieves road noise blocking and absorption, also achieves decomposition of automobile tail gas and further has a flow guide function, and the problems including the poor noise insulation effect, single function and the like of a traditional noise barrier for a road are well solved.

Description

technical field [0001] The invention relates to the field of road accessory engineering, in particular to an active powder concrete sound barrier. Background technique [0002] While highways and railways bring convenience to residents’ travel, they also bring huge noise pollution. The noise generated by roads and railways built in residential areas seriously affects the quality of life of surrounding residents. Sound barriers are a way to block and reduce noise. an effective means. Sound insulation walls are mainly used for sound insulation and noise reduction in transportation and municipal facilities such as expressways, elevated composite roads, and urban light rail subways, to control the impact of traffic noise on nearby urban areas, and can also be used for sound insulation and noise reduction in factories and other noise sources. It is generally divided into pure sound insulation reflective sound barriers, and composite sound barriers that combine sound absorption a...

AI Technical Summary

Problems solved by technology

[0003] The survey found that the traditional sound insulation wall has defects such as insignificant sound insulation effect and single function

For example, the Chinese invention patent CN105064231A discloses an environmentally friendly sound insulation wall for roads. The lower part of the sound insulation wall frame is provided with two sound insulation panels with a gap in the middle, and the upper part is provided with two glass panels with a gap in the middle. The sound insulation panel and the glass panel Separated by a partition in the middle, it has a certain sound insulation and sound absorption effect, but the use of glass plate material is not safe and does not play an ecological and environmental role.

For example, the Chinese invention patent CN204080659U discloses a sound-proof wall for expressways. The plug-in slots are fixedly arranged on both sides of the column body, and two plug-in slots are arranged on each side. The wall panels are arranged in the plug-in slots. The production process is complex and Single function

For example, Chinese utility model patent 97226381.0 discloses a highway sound insulation wall, which also has problems such as general sound insulation effect and single function.

[0004] On the whole, the new sound barriers published in the literature have problems such as complex process and single function to a certain extent, and some products use brittle materials, which have potential safety hazards
