Its concentration of emission remains high for a long time.China's Urban Building Construction scene airborne dust discharge intensity is big, for the main source of PM10
One of, air quality is had a significant impact.
Dust controlling measure is divided into two kinds of forms: one is Prevention method, and it two is Mitigation methods.Prevention method refers to change
Producing activity pattern, from the generation of front-end control airborne dust, Mitigation methods is to take engineering means to reduce airborne dust discharge intensity.Different
Airborne dust source control efficiency under different measure is different.Wherein reduce mechanical disturbance intensity, moistening and surface, solidification airborne dust source, subtract
Slow wind-force is the measure generally used on the impact of polluter.The most common dust-suppression method in domestic construction construction site is more
Traditional watering dust suppression, the method is big to the demand of the water yield, and the effectiveness persistent period is short.Watering can aggravate exposed earth's surface repeatedly
Weathering speed, it is easier to produce respirable dust.Part building site is abroad had to utilize New Dust-Depressor to be sprayed at open ground
Surface controls construction fugitive dust, obtains better effects.Show according to director association of US West (WGA) statistics, by dust suppression skill
The non-paved area that art is applied in construction project, dust suppression efficiency is up to 84%.
The anti-dust effect of the dust controlling measure that current domestic job site is commonly used is poor, does not has and improves urban atmosphere
The effect of environment.Due to job site air be dried, eolian erosion strong, general dust suppressant humidity is difficult to keep for a long time pressing down after declining
Dirt effect.
Summary of the invention
[solving the technical problem that]

Fruit substantially, is treated during wind that dust suppression region surface, without playing a dirt phenomenon, and has Dense mesh screen drawknot, treats that dust suppression region surface is without crack.
Dust suppression is tested
With manually dust suppressant being sprayed onto the surface, trial zone covering Dense mesh screen in advance.Part in trial zone and check plot
Two TSP concentration monitor points are not set, place monitoring instrument, by continuing to monitor the TSP concentration of trial zone and check plot, and tie
Close and observe the apparent breakoff phenomenon of dust suppressant, the anti-dust effect of assessment dust suppressant.The specification of this type of TSP sampler of this experimental evidence is built
View, uses 24h uninterruptedly to sample, and every day after filter membrane numbering is changed filter membrane and weighs, carry out data record.Date of test: November 5
Day～November 29.
Dust suppressant forms the dust suppression film that a layer thickness is about 7～10mm on bare soil surface, and by Dense mesh screen drawknot, causes
Close without crack.Pilot region dust controlling effect is obvious, and during wind, surface, trial zone is without playing dirt phenomenon, and has Dense mesh screen drawknot,
Surface, test block is without crack.
Collect trial zone and the data of the ambient air total suspended particles amount of check plot in the same period, obtain following knot
Really: within the Dense mesh screen dust suppressant test monitoring cycle (1,1/5 11/29 days), use Dense mesh screen dust suppressant region compared to not making
Substantially reduction, average dust suppression efficiency (i.e. TSP concentration difference is divided by the TSP concentration of blank group on the same day) is all had by region TSP concentration
Being 20%, anti-dust effect is obvious.Check plot and the TSP concentration difference of test block, maximum (November 7) reaches 0.43mg/m3.Examination
Test in the cycle, November 14,18 19 days, 23 24 days, 27 daily have bigger rainfall, affect dust measuring precision.Get rid of shadow
Ring the interference of the rainy weather of measuring accuracy, calculate the dust suppression efficiency in non-rainfall sky, obtain the dust suppressant dust suppression efficiency in non-rainfall
Reach 26%.
Result of the test shows: the atmosphere particle concentration of trial zone reduces by 20% compared to check plot meansigma methods, and dust suppression is imitated
Fruit is substantially.Dense mesh screen strengthens the surface of trial zone, has aobvious for the Ability of Resisting Disturbance of the exposed soil body and the durability of dust suppressant
Write and promote.Study through this topic experiment, it is proposed that the use Dense mesh screen dust suppressant on long-term (30 days) exposed earth's surface in construction site
Dust suppression mode, anti-dust effect is up to most preferably.
From above example and test it can be seen that the embodiment of the present invention is by being sprayed on covering by film-forming type dust suppressant
The soil surface of Dense mesh screen forms thin film, utilizes this thin film to be combined with Dense mesh screen and covers and soil mass consolidation surface, keeps soil
Moisture content, suppression airborne dust discharge, there is preferable anti-dust effect.
It is to be appreciated that the embodiment of foregoing description is a part of embodiment of the present invention rather than whole embodiment, the most not
It it is limitation of the present invention.Based on embodiments of the invention, those of ordinary skill in the art are not paying creative work premise
Lower obtained every other embodiment, broadly falls into protection scope of the present invention.
