Prefabricated buildings build "green" Hongqi Village

Recently, the reporter walked into Hongqi Village, located in Xujiawan Street, Weiyang District, Xi'an City. At this time, low-rent housing in Hongqi Village is being built here. The construction site is busy, and various work is progressing in an orderly manner. There is a scene of tower cranes standing in full swing.

Entering from the gate of the construction site, the main road is paved with steel plates as a temporary construction road, and the road surface is not easy to dust, and it is clean and tidy. "For the steel road at the gate, we use I-beams and steel plates as temporary construction roads. Compared with concrete roads, steel roads are more environmentally friendly and have a smoother look. And all I-beams, angle irons and steel plates can be used in multiple turnovers, thereby reducing production costs. “ explained the builders.

When it comes to the highlight of the project, we have to mention the prefabricated construction process. Inside the building, some high-precision formwork, prefabricated stairs, prefabricated laminated panels, ALC wall panels, laminated walls and other components are placed on the ground, waiting to be assembled and installed. In addition, prefabricated construction technologies such as integrated kitchens, integrated bathrooms, and dry floor integrated heating modules will also be used for the interior decoration of the rooms in the later stage. The overall assembly rate of the project can reach 42%. Compared with traditional decoration, prefabricated decoration can greatly shorten the construction period and save resources.

In addition, green production can be seen everywhere at the construction site. In the corner of the construction site, a dust monitor is working. According to reports, the dust monitor can be linked to the automatic control of the sprinkler system. After switching to the intelligent sprinkler and dust reduction mode, the system will automatically start to work. That is to say, after the monitor detects that the particulate matter on the construction site exceeds the standard, the central control system will send a command to the intelligent spraying equipment through the intelligent computing processing, so that it will automatically start the dust reduction operation, which not only reduces the manpower input, but also improves the work efficiency. In addition to dust monitors, new energy sprinklers, cutting dust collectors, car wash sheds, pump pipe sedimentation tanks, high-pressure dedusting water cannons, and woodworking can also be seen on site.

In terms of "five festivals and one environmental protection", the Hongqi Village project is also making more efforts. For example, in terms of water-saving measures, the project has set up a rainwater recovery system on the roof of the garage, and water-saving appliances are used for domestic water in the office and living areas of the construction site. In terms of material saving, the used short square wood and broken square wood with a length of more than 80 cm are reused for other construction sites through the docking method. The use of concrete is expected to make concrete prefabricated bricks, which are beautiful and elegant, and can be turned over many times in the later period; in terms of energy saving, wind energy and solar street lights are installed in the main channel to reduce the consumption of outdoor lighting electricity. LED light strips are used for lighting in the construction room. Among them, the three tower crane headlights at the project construction site use domestic advanced LED high-power floodlights instead of traditional light-off lights. The normal service life is 10 years, and the luminous intensity is about 16 times that of incandescent lamps of the same power, and the tower headlights are also set to automatically switch on and off.

It is reported that after the completion of the project, it will provide more than 500 low-rent housing, effectively solve the housing problem of some low- and middle-income families, and help China achieve the social goal of "appropriate housing for all", the "people-oriented" value and the concept of a harmonious society of "benefiting all the people".
