Chuanhui District, Zhoukou City, Henan Province is perfecting the industrial chain of prefabricated construction

"Eat" into the trash and "spit" out the building materials. At Zhoukou Xingyuan New Building Materials Company, various construction wastes are sent to the crusher to be broken into particles of different sizes, and construction dust and steel bars are spit out from two outlets. The remaining material is conveyed to the screening machine through the conveyor belt, and flows out from 5 outlets according to the particle size. The largest particle can be used as a water-stable layer of the road, and the second largest particle can be used as a stone to make concrete. The smallest particles can replace sand and gravel to produce permeable bricks, slope protection bricks, grass-planting bricks and other products, which are used in the construction of sponge cities, which strongly promotes the construction and development of Zhoukou city.

Xingyuan New Building Materials Company is an enterprise engaged in the resource utilization of construction waste. It has witnessed the ongoing "green building" industrial innovation in Chuanhui District, Zhoukou City, Henan Province.

In recent years, based on the advantages of location, market and industrial foundation, Chuanhui District has actively promoted the adjustment of the industrial structure around the leading industries of new building materials, attracting and fostering dozens of new green building materials companies. The products cover multiple aspects of building main structure, building materials, smart home, construction waste recycling, etc., forming a new type of building materials industry cluster with complete types, large-scale agglomeration, and complete supporting facilities, with an annual output value of more than 10 billion yuan.

As an emerging industry and a sunrise industry, prefabricated buildings are the development direction of future buildings. Drawin Group Zhoukou Green Building Technology Park and Henan Zhugong Technology Industrial Park are representatives of the prefabricated construction industry in Chuanhui District.

Drawin Group is a well-known leader in the field of domestic prefabricated construction, and Zhoukou Green Building Science and Technology Park is one of the important supports for its establishment in the Central Plains. Liang Zongyuan, the person in charge of the science and technology park project, said that the project started in 2020 and put into production that year, with an annual output of 250,000 cubic meters of PC components. The automated production line of the base includes a central control system, a mold pretreatment system, a maintenance system, etc., which can realize intelligent production such as central intelligent real-time monitoring system management, fully automated flow of assembly lines, precise positioning of molds with laser technology, and high-precision standardized fabrics.

Steel structure is also the key development direction of prefabricated buildings in Chuanhui District. Not long ago, the Henan Zhugong Science and Technology Industrial Park project was officially put into operation. As a key project in Henan Province, the project covers an area of 240 acres and has a total investment of 2.5 billion yuan. It is the largest steel structure production base for prefabricated buildings in China. The company adopts the most advanced steel structure production line in China to provide services for many steel structure prefabricated construction projects in the province.

"The implementation of these two projects has lengthened and improved the chain of the prefabricated construction industry in Chuanhui District, and the pattern of dual-headed leadership and coordinated development of upstream and downstream related enterprises has been formed." said Hu Youtao, the head of Chuanhui District.

In recent years, relying on Henan Zhugong Science and Technology Industrial Park and Drawin Group Zhoukou Green Building Science and Technology Park, Chuanhui District has driven the deep integration of more than a dozen industrial chains and innovation chains, such as Great Wall Lejia Whole House Customization, Yonzhiyou Glass, Yuantong Pipe Industry, and Xingyuan Building Materials. Put the concept of green environmental protection throughout the entire life cycle of green buildings from R&D, production, application to waste recycling, lengthen the industrial chain of green prefabricated buildings, and enhance the stamina of industrial clusters.

In order to promote the transformation, optimization and upgrading of the traditional industrial structure, Chuanhui District continues to promote the "three major transformations" (technical transformation, intelligent transformation, and green transformation) to promote the high-quality development of the enterprise. Among them, Jinhua Xia Construction Engineering Group invested 20 million yuan to jointly develop a new type of hollow row column steel structure residential system and engineering application technology system with Hangzhou Tonggenshu Architectural Structure Design Office. The Jiayiliang insulating glass project introduces full CNC edging and cleaning equipment, automatic insulating glass equipment and the most advanced 6-meter flat-bending integrated tempering furnace, filling the gap in the city that there is no large-scale tempering furnace. Great Wall Doors vigorously implements a green assembly-type decoration production line, establishes a digital model, realizes digital management of the entire operation process, and realizes the interconnection and integration of information between intelligent logistics and other equipment.

"In the next step, Chuanhui District will fully implement the requirements for the development of prefabricated buildings, and make every effort to promote the high-quality development of green buildings." The traditional industry of building materials has realized the transition from "gray manufacturing" to "green manufacturing", laying a solid foundation for the development of ultra-low energy consumption green buildings.
