Abstract: With the rapid economic growth in China, the construction industry is also experiencing a rapid development, but such rapid developmentalso brings negative effects. Among them, the environmental pollution problemperhaps has the greatest impact, so the linkage technologyof construction site environmental monitoringand dust removal is adopted. Thattechnology is speciallydesigned for the construction siteenvironment, whichmonitors from the very beginning with the equipment of advanced technologysuch as Internet +, big data and cloud platform. It uses water jet technology for efficient atomization of water particles, so that droplets adsorption dust particles, and suppress the dust effectively. The dust removal effect of the linkage system is obvious, and it can minimize the environmental pollution of construction site and achieve the desired environmental effects.
