Description
Technical field
The present invention relates to dust falling device technical fields, device for reducing dust and its depositing dust side more particularly, to a kind of temporary pavement
Method.
Background technique
In engineering construction place and open pit transportation mode, dump truck means of transportation is widely applied.Due to
The temporal characteristics of engineering and place, the road in engineering construction place, opencut getting working face and casting line are typically all not
Road surface is built, and only through the appropriate dirt road for flattening, being compacted, form temporary pavement.The operation of engineering construction place and opencut is special
Point is all that short distance, high density are open to traffic that rate, transport vehicle tonnage are larger etc., and operation mode is caused per when the vehicle is running, and dust is more
Unrestrained, dust in air concentration may be up to tens to several hundred mg/m3。
Since engineering construction place and two kinds of opencut of operating condition are about the same, carried out by taking the operating condition of opencut as an example below
Analysis.According to the opencut field data of the former Soviet Union, Automobile Transportation road surface dust emission accounts for the 70%~90% of the total dust-producing amount of full mine, right
Ambient contamination is extremely serious.As it can be seen that the prevention and treatment of opencut road surface fugitive dust is particularly significant and urgent.Road surface fugitive dust is reduced,
Key, which is to maintain road surface, certain water content and good pavement behavior.For this purpose, watering can be taken, solid soil stabilization road surface, used
The measures such as hygroscopic inorganic salt material or cohesive material dust suppression.
The degree of stability and bearing capacity on opencut soil property road surface depends mainly on compaction and the material on road surface
Shearing strength.Compaction is good, and road surface is destroyed just slow；The shearing strength of material is the function of soil type and state, due to
The continuous variation of soil conditions, in 1 year, the shearing strength of dirt road shows very big fluctuation, thus it is unstable, therefore, soil
Under the wheel load effect of heavy duty dump truck, road surface and subsoil will all generate certain stress, and thus produce on matter road surface
Raw certain deformation；In addition also due to rolling the rubbing effect of wheel and repeating the influence of load, road surface is destroyed quickly, shape
At rough surface.Frequently due to vehicle operation, when the road surface being destroyed and Automobile Transportation ore-rock, the ore-rock scattered exists
Rolling and crumpling down repeatedly for wheel generates a large amount of dust, therefore, when the tire of locomotive is pressed on uneven surface in traveling,
Air in those holes is compressed, and when wheel is crossed from the stranded air pressed against, air will expand suddenly, and road pavement generates
One very strong suction (or suction) effect, forms one powerful impact air-flow, raises the dust on road surface.
Opencut soil property road surface is subject to be damaged under heavy duty dump truck effect, generates a large amount of dust.From point above
Analysis is it is found that this is mainly due to the solid, liquid, gas three-phases of the composition soil road soil body to have variability, and the connection between soil particle
It is faint, external force and the water resistant such as the load action of anti-running automobile wheel, the rubbing effect for rolling wheel and stronger suction effect
Performance is lower.Therefore, it need to be consolidated with physics, physical chemistry and chemical method, be allowed to preferable physical mechanics and durable
Performance.The three elements of consolidation are densification, particles cured and contact solidifies.There are many method of use, including Mechanical Method: compacting is solid
Soil, particle are with the solid soil of grade mixed compaction；Humidification method；The solid soil of watering；Cementing method: cement adds the cement soil fixation of outer-penetrating agent, lime
Add the solid soil of the lime of outer-penetrating agent, pitch or add the solid soil of the pitch of outer-penetrating agent, tar or add the solid soil of the tar of outer-penetrating agent, pitch and
The solid soil of tar；Chemical method: chloride, phosphoric acid, resin, calcium acrylate, aniline-furfural, sulfite waste liquor and the chemical dust suppression of synthesis
Local method is consolidated in agent etc.；There are also the various solid comprehensive synthesis used of indigenous method to consolidate local method.
These existing methods more or less have some defects: at high cost, low efficiency, waste water, road surface slippery situation causes to pacify
Full hidden danger, complicated for operation etc., it is therefore desirable to a kind of easy to operate, inexpensive and efficient dust-removing method.
