Construction ventilation and dust prevention in alley The alley, as a dividing line between the roads of urban residents and the interchange of roads, has special space characteristics and affects the orderly operation of urban construction. The construction dust, which cannot be easily discharged in the alley, will cause great harm to the local peoples health, so a good dust prevention measure needs to be put in place.
The most important measure is to set up dust prevention fences in the alley. Dust prevention fences are the first line of defense in alley construction dust prevention. In addition to setting up dust barriers for construction entrances and exits, the dust fence should also be set up along the whole side of the alley. This dust-proof fence should be 50 centimeters high and use non-toxic and harmless materials. The dust fence should not have gaps and can be designed with bar-shaped columns, arrow-shaped fence sections or double-cross structure.
In addition to dust fences, other measures need to be taken in timely. Right before construction starts, spraying a layer of wet cement on the surface of the road can greatly reduce the amount of dust in the air. During the construction, there should be increasing frequency of water flushing and wetting the surface of the roadbed in order to effectively prevent the dust from contaminating the local environment. Also, construction machinery should be equipped with dust collectors and filters to reduce the emission of construction dust.
At the same time, construction workers should wear masks when handling construction tasks and pay attention to personal hygiene so as to reduce the chance of contact between dust and human bodies. Furthermore, a complete dust removal system should be established around the construction site to prevent dust from entering the atmosphere. The dust removal system should include a wet curtain, a filter device and an exhaust fan, which can collect dust from the construction site and process it through these devices.
To sum up, construction ventilation and dust prevention in the alley are very important, and the roads and alleys of urban residents are important passages for home life. Therefore, in construction projects in the alley, people should do a better job of dust prevention and pollution control, establish a complete dust collection and filter system, and use protective measures accordingly, so as to protect the health of the local residents.
