The renovation of old residential areas is not only a practical matter of people's livelihood that benefits the people, but also an important starting point for urban renewal, and it is also a hot spot for people's livelihood that residents have always paid attention to. Recently, the first batch of pilot projects in Beijing to carry out renovation in the mode of "original demolition and original construction" - Building 8 of Huapichang Hutong has completed the capping of the main structure, and in the first half of this year, the original residents can move into their new homes in situ.
It is reported that the No. 8 building of Huapichang Hutong before the renovation is a 5-storey single residential building, the old house built in the 70s is in disrepair, the structural system is old, the equipment pipeline is aging, the thermal insulation effect is degraded, and the fire hazard is prominent. In addition, problems such as disorderly outdoor environment seriously affect the living environment and quality of life of residents.
The 20 households in Building 8 of Huapichang Hutong hope to live in a safe and comfortable new house as soon as possible, improve their living environment and improve their quality of life. As the contractor of the project, in order to build Building 8 of Huapichang Hutong faster and better, so that residents can move back to the new house as soon as possible, China Construction Hailong Technology has introduced a new prefabricated construction process, that is, modular integrated building (MIC building) technology.
Different from the traditional prefabricated component assembly, the modular integrated building can split a building into independent modules to the greatest extent, each module unit is a closed reinforced concrete box, with its own decoration and equipment, and the box can be hoisted in place on site and then connected by concrete pouring to form a reliable whole, so as to achieve "building a house like a car".
The modular integrated building moves the building from the construction site to the factory, changes the serial project of traditional construction into a parallel project of the factory and the construction site, and changes the vertical operation into a plane flow operation, which solves the problem of difficult on-site construction and shortens the project period by 75% compared with the traditional construction period. It only takes about 3 months for residents to move out to hardcover delivery and move back in, and they can spend a reunion in their new home during the Spring Festival this year.
In the process of demolition and reconstruction of the original site, if ordinary construction methods are adopted, it will take a long time and cause a lot of noise and dust. However, modular integrated buildings can reduce construction waste emissions by 75%, reduce material waste by 25%, reduce dust pollution and noise disturbance, and are feasible technical solutions to solve the renovation of dilapidated buildings in old communities.
In addition, CSCEC Hailong Technology uses digital means to open up the six links of design, production, transportation, construction asset delivery and management through BIM technology, and integrates digital design, intelligent production, intelligent transportation, intelligent construction, intelligent operation and maintenance and other customized full-life cycle intelligent construction solutions to realize the whole process of intelligent management, ensure the orderly connection of the construction process, and the coordination and efficiency of construction organization, so that "standardized construction" can escort "speed".
The implementation of urban renewal action is a major measure to promote the solution of outstanding problems and shortcomings in urban development and enhance the people's sense of gain, happiness and security. In the future, CSCEC Hailong Technology will continue to promote the application of innovative technologies, empower the transformation of old communities with science and technology, and effectively turn "small transformation" into "big people's livelihood".
