Ji'nan real estate "dust removal" dilemma: environmental protection facilities display
broken dustproof net, bare loess heap, fuzzy construction road... Whenever a vehicle passes, it rolls up waves of loess and looks far away. The whole construction site is enveloped in smoke and dust.
this is a true portrayal of a real estate site in the eastern part of Ji'nan. In fact, there are still many construction sites in the eastern area like this. As the project is dense, and the construction parties do not attach importance to the dust control, there are often four dusts, and the constructor's perfunctory attitude also makes the area become a heavy disaster area of the building dust.
in the construction of real estate intensive East Ji'nan, the air quality has become a hot spot of attention in recent years, and the dust caused by construction construction has also become the main source of inhalable particulate matter pollution. According to the "2014 Ji'nan PM2.5 source analysis results" issued by the Ji'nan Environmental Protection Bureau, the main sources of PM2.5 in the air of Ji'nan are coal and dust, among which, 24% of the dust is raised.
yesterday, the reporter passed through the East Ji'nan iron and international yand, a car roar, with the car bumps all the way down the dust makes the passers-by difficult to fight, one after another to hide their nose.
China Railway International Yi locates densely located sites, and roughly estimates that the number of properties currently under construction is 10. According to nearby residents, 3 years ago, it was Nanhu village and Bei Hu village. In 2009, the village was dismantled and the house began to be rebuilt. As the project started, the dust pollution caused by the construction had been criticized.
construction parties perfunctory "dust" facilities in the form of virtual
2013, the Shandong issued relevant regulations on the management of the control of dust pollution, however, there are not many enterprises in the actual implementation. As for the governance of "dust", we all support it.
in accordance with the regulations, the construction units should harden the ground and vehicle roads in the construction site during the construction period; cover materials such as engineering materials, sand and stone and other materials that easily produce dust; and the flushing platform should be set up at the exit and entrance of the vehicle.
however, the actual situation is that most of the construction sites on the surface do this, but careful observation will find that many site sand and stone bare, the dust net is only a symbolic cover; the construction site of the construction site is hardened, but the hardening is not complete; the cleaning and setting of the entrance and exit vehicle is set in the same shape.
yesterday, when the reporter visited the area, it happened to catch up with the vehicles that transported the residual soil. As the road was not completely hardened, the vehicle passed and the ground had rolled up the dust. Besides, there are several bare mounds on the east side of the entrance, and pedestrians have to hold their mouths and nose to hold their breath. The reporter observed about half an hour in the vicinity, and the traffic was not less than ten times.
when environmental benefits meet the economic interests of the site "dust removal" in the face of the dilemma
construction personnel told reporters that the reason why the dust is rampant, with the builders perfunctory attitude has a great relationship, but the most fundamental or economic interests. "During construction, workers always cover up building materials and dust, which not only delays construction, but also wastes manpower and material resources," the worker said.
and Mr. Zhao, who is responsible for managing a construction site in the area, told reporters that enterprises are pursuing economic benefits, and construction units are no exception. The construction party contract the developer's project, and the developer pays limited money, in order to realize the maximum economic benefit, the construction party generally does not want to put the energy into the dust.
in addition, the developer's project has time limit, so long as the developers do not delay, the developers will not interfere. For some specific regulations, such as the cleaning of the construction site of the vehicle, the construction party also has the measures to deal with. The construction party installs the cleaning equipment according to the regulations, but does not use it for a long time. "It will only open at the time of inspection." Mr. Zhao said to be frank, cleaning a car for at least 7, 8 minutes, the residue is also charged, "the construction party will not delay the time and cost of the vehicle to dust the vehicle."

Construction site workers explained that the gravel pavement porous, good dust, water, noise, unloaded dust, dust in the gravel pore, this is a good way to control the site of dust.
South Korea:
site workshops management
according to "Yangzi Evening News", South Korea's management of construction sites is workshops, and entering the site is like entering a well-organized workshop. The whole site is separated into a block of work area by the yellow line. It is a bit like the main road and the secondary road, which the intersection Department has drawn on the road, and is very striking; the cleaning in the operation area is very neat, and no one should take up the line.
in the area where all kinds of building materials are stacked, they are covered with rainproof cloth because they are open-air. Construction waste such as waste concrete, sand and waste bricks are all used as raw materials for building road infrastructure, greening and landscaping. Even if it is necessary for Sinotrans, the muck truck has been dustproof and sealed in advance.

some friends who have been to Japan, once sighed that they saw the site, very neat and clean. On the eve of World Expo, Shanghai, Jiefang Daily found that the Japanese pavilion built in the Expo site was "special" without dust. One detail can explain the strict management of the Japanese site: every local car entering and out of the site must be monitored by the manager's site, and after cleaning the tires with a brush, a high pressure water gun and a mop, it is necessary to leave. According to experts, Japan and other developed countries have implemented the "5S movement" for many years, that is, sorting, rectifying, cleaning, standards and upbringing.
