Description
Technical field
The invention belongs to road travel noise abatement technical fields, it particularly relates to be integrated to a kind of based on flyash
The environment-friendly type road sound barrier utilized.
Background technology
With the fast development of highway communication, the travel speed of vehicle is getting faster, the road noise problem thus brought
It is more and more prominent, it is one of to eliminate and obstruct the most economical effective method of noise in both sides of highway setting sound barrier.Sound-screen at present
Barrier research is concentrated mainly on plastic-steel board, the coloured silk of concrete slab, steel plate, various light materials (glass fibre, mineral wool, asbestos etc.)
Steel plate etc., they are each advantageous, and there is also certain disadvantages.Sound-absorbing material of the country for road sound barrier is mainly thin glass
The inorfils class material such as cotton, mineral wool, intensity is relatively low, and brittleness is easily broken, and secondary pollution is easily caused after dust formation, after water suction is made moist
Sound absorbing performance weakens significantly, and there is an urgent need for seeking a kind of novel sound-absorbing material to overcome existing sound-absorbing material intensity low, durability is poor, ring
The deficiencies of border adaptability is weak and the feature of environmental protection is poor, develops high-performance novel noise barrier structure.
Primary solids waste of the flyash as coal-fired power plant, it has also become the single dirt of maximum of Chinese industrial solid waste
Dye source, it is enriched the heavy metal substance that a large amount of arsenic, lead and selenium etc. are detrimental to health and other pollutants.In China, mostly
Addressing, anti-flying, antiseep, the Anti-lost measure of number ash field are far not enough to reach the mesh of effectively prevention flyash environmental pollution
's.The sandstorm of approach the north of China main coal-producing area and thermal power plant is swept along and is largely handled on the way without non-proliferation
Flyash is transferred to North China, East China even Hongkong and Macro Tai Area, forms " coal dust is sudden and violent " for having great threat to public health.Fine coal
Ash comprehensive utilization has become one of Domestic Resources and the hot spot of Study on Environmental Protection.
Lytag has following excellent performance：(1) density is small, light.Its appearance is hard, and there is many in inside
More micropores；(2) heat preservation, heat-insulated, sound absorption, are more than 0.5 with the standby porous material average sound absorption coefficient of coal ash for manufacturing；(3) fire resisting
Property it is good, haydite have excellent fire resistance.Studies have shown that at a high temperature of 650 DEG C, haydite concrete can maintain intensity under room temperature
85%, and normal concrete can only maintain the 35%-75% of intensity under room temperature；(4) anti-seismic performance is good.Haydite concrete due to
Light weight, elasticity modulus is low, and anti-deformation is good, has preferable anti-seismic performance；(5) water absorption rate is low, anti-freezing property and durable
Performance is good.Above-mentioned excellent properties based on lytag can both efficiently use fine coal using it as sound barrier main material
The sound absorbing performance of grey porous material, and flyash can be largely consumed, and this kind of consumption ways will not cause secondary pollution, be one
Kind cleaning, efficient Land use systems have significant economic, social and environmental benefit.
