Research On Dust Emitting And Safe Distance In Construction

In the process of urbanization, a large number of the old building was torn down andnew buildings, produce a large amount of construction dust, serious damage to the naturallandscape and ecological environment. In addition, the development of new buildingneeds a lot of construction workers into building a line up, and led to patients withsilicosis were rising sharply, seriously affected the social labor group’s health and normallife. Due to construction dust silicosis need timely treatment, because in the constructionsite is more, the demand for construction workers, lead to more construction workerssuffering from silicosis, overall, could avoid the high treatment to the society has broughtthe enormous waste. In accelerating the development of urbanization, therefore, at thesame time, strengthen the construction process of dust protection, minimize constructiondust of construction workers and surrounding residents physical harm, adhere to thepeople-oriented, building a conservation-minded society, to form individual and socialharmonious development is of great significance.Based on building construction dust produced in the representation of the process asthe research object, using the simulation analysis and field measurement analysis method,combining the analysis of the distribution of construction site dust, and then reflect theharm of the construction site dust and the deficiency of the traditional dust controlmanagement. Fluid mechanics in the simulation section, based on FLUENT simulationsoftware to the construction site dust trajectory is simulated, the image intuitively showsthe specific job link construction sites around the concentration distribution, determine theconstruction link in safety area and dangerous area; In actual analysis section, through thestatistical analysis of field measured data describes specific process of dust distributionfunction, confirmed the consistency of simulation results; Finally, the simulation analysisand field measurement based on the results of analysis, combined with the relevant duststandards, methods of protection in the process of construction and selection of equipmentare analyzed and the suggestion, for the construction management personnel to providetheoretical basis for dust hazard control strategies.
