Abstract

The invention discloses an ultra-high performance concrete decorative air purification type sound barrier unit prefabricated slab and relates to the technical field of traffic construction. The prefabricated slab comprises a self-cleaning sound-absorbing layer, a structural layer and a decorative layer. The self-cleaning sound-absorbing layer is made of sawdust, nano photocatalytic materials and cement mortar, the structural layer is made of alkali-resistant glass fiber gridding cloth reinforced ultra-high performance concrete, and the decorative layer is made by adopting an embossing process.In the invention, the nano photocatalytic materials are absorbed by utilizing loose and porous characteristics of industrial waste sawdust; the self-cleaning sound-absorbing layer has triple effectsof absorbing sound, being hydrophilic and self-cleaning and decomposing harmful substances in air; and meanwhile, the structural layer further improves the strength of the ultra-high performance concrete through the alkali-resistant glass fiber gridding cloth, the decoration effect of the decoration layer is optimized through the embossing process, durability is good, and decoration is attractive.

Description

Technical field: [0001] The invention relates to the technical field of traffic construction, in particular to a prefabricated panel of an ultra-high-performance concrete decorative and air-purifying sound barrier unit. Background technique: [0002] Residents on both sides of the highway traffic line are often trapped by the noise generated by the vehicles and the large amount of harmful gases emitted by the vehicles. Installing sound barriers on both sides of the road can only reduce the sound produced by vehicles during operation beyond the volume that people can bear in life, and cannot reduce the impact of harmful components emitted by vehicles on the environment. [0003] The sound barrier is mainly made of resin plastic, metal material and prefabricated concrete plus sound insulation cotton and other materials. The cost of resin plastic and metal sound barrier materials is high. Resin plastic is easy to age when exposed to ultraviolet light in sunlight, and metal mat...
