on April 10, at the gate of Haibitai Phase II construction site, a large yellow truck was preparing to leave the construction site, but before leaving, it had to pass through a "checkpoint", that is, the vehicle cleaning equipment at the gate of the construction site. The tires and bodies of the truck could only leave after being washed and cleaned. "This is to prevent vehicles from carrying mud on the road and causing dust pollution when driving." The person in charge of the site told reporters.
Reporters learned from the Municipal Housing and Construction Bureau that with the warming of the weather, most of the construction sites in Qinhuangdao City have resumed construction, and the dust control work has been followed up synchronously, especially in spring, when there are more windy weather, more stringent measures need to be taken to solve the dust problem in construction sites.
According to the Measures for the Prevention and Control of Dust Pollution in Hebei Province and other documents, effective measures should be taken to prevent and reduce dust pollution in construction projects, so as to ensure that the discharge of dust pollutants in construction sites meets the national and provincial pollutant discharge standards. Construction sites are required to set up public signs at obvious locations at the entrances and exits of the construction site to publicize information such as the person in charge of the construction site, environmental protection supervisors, dust-proof measures, dust supervision and management departments, and complaint calls; A hard enclosed enclosure or wall shall be set around the construction site, with a height of not less than 2.5 meters for the main road section and 1.8 meters for the general road section, and an anti-overflow seat of not less than 0.2 meters shall be set at the bottom of the enclosure; Hardening treatment shall be carried out for the entrances and exits of the construction site, construction roads in the site, material processing and stacking area, office area and living area, and the ground shall be kept clean; vehicle cleaning facilities shall be set up at the exit of the construction site, and supporting drainage and mud sedimentation facilities shall be set up, and vehicles shall not leave until they are washed clean; When building materials such as ready-mixed concrete and ready-mixed mortar are used in accordance with regulations and can only be mixed on site, dust-proof measures shall be taken; when powdery and granular building materials such as cement, lime soil, sand and stone, and construction earthwork, which are likely to produce dust, are stacked in the construction site, dust-proof measures such as sealing or covering shall be taken, and dust-proof measures shall be taken during loading, unloading and handling; The construction waste shall be cleared and transported in time. If it is piled up in the site, it shall be piled up in a centralized way and dust-proof measures such as sealing or covering shall be taken. In the process of earthwork construction, the time of earthwork excavation and retention shall be reasonably controlled, and dust-proof measures such as sprinkling and spraying shall be taken on the working surface; In the construction of high-altitude operations, the construction waste on the construction floor shall be transported by closed pipelines or bagged by vertical lifting machinery, and it is forbidden to throw or scatter it at high altitude. Li Yunpeng, Secretary of the branch of
the Municipal Construction Safety Service Center, introduced that the staff of the center would inspect and supervise the implementation of dust control measures one by one before the start of construction. At present, in accordance with the standards of safe and civilized construction sites, the city has cultivated 10 benchmarking demonstration sites, such as Haibitai, Jinmeng Bay No.1 and Hanhai Fengjing, so that all construction sites can learn from examples, and at the same time, continuously carry out law enforcement and inspection, especially strengthen the supervision of earthwork, external network operation and night construction, so as to eliminate the problems of inadequate measures. The command platforms at the city, county and district levels continuously investigate and push problems 24 hours a day, and promptly remind the relevant construction sites to reform the existing problems.
