Block B of Northwest Lake in Zhongtian Liujian Dingyu:

The grass wall makeup that "breathe"

Military transport slogan outside the green fence

At the intersection of Hankou Qingnian Road and Huangxiao West Road, Dingxi Northwest Lake Block B project is standing upright. As a demonstration project of the "six chemical" management standard of Zhongtian Sixth Construction Company, continuous on-site environmental improvement on the site is remarkable.

This project newly built 2 super high-rise office buildings and 3 floors of commercial podiums. The site is equipped with monitoring devices such as dust and noise, and is equipped with building sprinklers, fog cannons, and mobile sprinklers. "It's so good. I didn't expect the construction site enclosure to make such a good 'background wall'." On the afternoon of the 19th, the reporter saw on the spot that a 6-meter ecological green fence was set up around the project enclosure. There are spray paintings related to the military games, and pots of fresh green flowers are embedded in the special green wall, which becomes a landscape on the street.

On-site project executive manager Chen Xiaodi said that the project department introduced the landscape design concept on the basis of the full use of tall green plant enclosures, and cleverly planted "breathing" real grass on the enclosures. Watering maintenance has beautified the construction site and social environment, and also highlighted the concept of healthy development, often attracting passers-by to stop and watch. At the construction site, except for the rebar processing area, all materials and processing areas are all set up in the basement to prevent noise and dust from material processing and stacking.

In order to create a good environment, Zhongtian Sixth Construction strictly manages and requires each project to self-examine and rectify in accordance with the "Atlas of Site Environmental Improvement and Improvement of the" Six Chemicals "Standard Atlas".

Urban Construction Bureau:

Strong support to create a good atmosphere for military transport

Chinese style walls line the streets

Ms. Liu, who lives in Wuchang, told reporters that before driving on some roads in Sanzhen, she would encounter potholes, breakages, and other road diseases. Now these roads have been upgraded and upgraded to become beautiful and smooth. The degree has been greatly improved, and the Chinese-style subway construction site enclosures are clean and tidy. The ecological green enclosure can even take pictures. "Great Wuhan is really different every day."

During the preparations for the military games, the Municipal Urban Construction Bureau set up a sub-command of the Urban Urban Construction Bureau of the Ambient Air Quality Assurance Command during the military games in accordance with the work arrangements of the municipal government and the Environmental Protection Department of the Military Games to coordinate the city construction management system Safeguard work to improve the level of civilized construction management in the city.

Taking the Military Games as an opportunity, the Urban Construction Bureau has stepped up the construction of urban road networks. Over the past year, a total of 42 urban roads have been constructed, including 33 key lines and 9 basic lines. The total length of the roads involved is about 1002 kilometers. The classification has improved the road environment, while facilitating the citizens' travel, and also improving the Wuhan urban road network, making the urban environment more tidy.

"Run a meeting well and invigorate a city." This is the direction of Wuhan's efforts. In improving the urban environment, relevant construction units and construction units around the city have implemented the 2018 version of the enclosure standards and the construction site "six transformations" management standards. Each construction project department uses tall green plant enclosures and antique garden enclosures to promote standard implementation. implement.

Today, looking at the three towns of Wuhan, some Chinese-style publicity pictures and public service advertisements are increasingly appearing on construction site fences, becoming "more fun" and "lovelier", becoming a landscape.

In terms of strengthening the standardization of construction sites, the Urban Construction Bureau emphasized the key points of improvement. In response to the common and dynamic issues such as untimely coverage of bare soil and random opening of enclosures, "grab repetitions and repetitions" and increase punishment. Construction sites that fail to implement and detect problems will be put in place within strict deadlines, and will continue to do a good job of public exposure of "ten poor construction sites" to form a concerted effort to supervise and compact the responsibility.

Continue to conduct third-party evaluations of site dust control. Each month, the companies of each district and platform are scored, and the scoring results are included in the assessment scope of the Urban Comprehensive Commission. For the problems found, the comprehensive management platform such as urban comprehensive management and air pollution prevention and control are issued to the districts to issue supervision notices, and one by one sales rectification is in place.

During the event, the Urban Construction Bureau's sub-headquarters will also strengthen dispatching and conduct comprehensive safeguard inspections on construction site safety production, dust and air defense, fuel machinery control, and fire control approval to create a good atmosphere for the military games.

Up to now, the PM10 concentration index related to construction sites in Wuhan has maintained a downward trend, and no dangerous accidents have occurred in construction sites in Wuhan.
