In the new era, high quality development is advancing. Intelligent manufacturing is the only way for the industry to move towards high quality development. In Changsha, struggling to build an intelligent manufacturing center, the construction of the industrial corridor of the west line of Ningxiang City is accelerating, and the Ningxiang Economic Development Zone is struggling to seek high-quality development. The blue moon Valley smart manufacturing pilot demonstration enterprise is increasing, and the concept of intellectual creation is increasing. Blue Moon Valley has become a wind. building materials industry
At the China (Changsha) Prefabricated Building and Construction Engineering Technology Expo held in Changsha in November 2018, the debut of China Construction Technology surprised many audiences: 75% of the assembly rate of China Construction Technology Changsha City Investment and Exhibition Project refreshed Hunan Province It is recorded that the construction area of 6 single units and about 30,000 square meters is only 90 days from the construction of the site to the completion of construction. Compared with the traditional construction method, it can save 80% of water, 40% of energy saving, 20% of materials and festivals. At 60% of the time and 20% of the land, the construction process can achieve “five-section and one environmental protection”, and achieve the goal of energy conservation, emission reduction and green development in line with national standards.
So what is a prefabricated building? To put it simply, building a house is like a machine, a batch of production, and then assembling the finished product, such as a assembly line, into a building. With curiosity, the reporter visited Zhongjian Technology Hunan Co., Ltd., located in the Economic Development Zone of Ningxiang, to gain an in-depth understanding of the “black technology” behind the industrialization of construction. wood-based panel industry
Committed to "technology development in the whole industry chain" to achieve green manufacturing
Zhongjian Technology Hunan Co., Ltd. is committed to “Technology R&D in the Whole Industry Chain”, breaking through the traditional secondary design pattern of prefabricated buildings, forming a prefabricated design system for residential systems, public housing systems, sports cultural facilities, and integrated factories. Complete sets of innovative technologies such as production systems, assembly and construction systems, information management systems, parts and components, and new materials research and development and application systems.
The industrialization base meets the production and production of all components of the assembly house and the subway tube piece, which ensures the advanced technology, and its manufacturing level, production efficiency and product quality are leading in China. The production plant consists of 4 PC component automation production lines and 2 automatic production lines for subway segments. The concrete mixing station in the factory can meet the production requirements of components. The scientific research departments of industrialization bases include technical centers, design institutes and laboratories. They have carried out research and development of a number of scientific research projects, participated in 2 national key research and development projects in the “13th Five-Year Plan”, and participated in one major research project of Hunan Province. There are 8 standards for national standards and provincial standards, and 37 achievements have been obtained for work methods and patents. A number of scientific research results have been applied to actual production applications.
The prefabricated architectural concept of “building a house like a car, buying a house like a supermarket” has penetrated into the hearts of every employee of CSC. CSR's prefabricated buildings adopt technology (EPC mode) of design standardization, production factoryization, on-site assembly, main decoration and electromechanical integration, and whole process management informationization, which not only greatly reduces construction waste, but also improves construction speed. It is 1.6 times the speed of traditional building construction and truly achieves green construction.
Construction of subway "body armor" to improve urban traffic conditions
The tube of Changsha Metro was also built by China Construction Technology Hunan Co., Ltd. According to the technical staff Tang Hong, the concrete strength and impermeability grade of the shield tunnel segment of Changsha Metro is relatively high, and the structural design life is not less than 100 years. The segments are closed and interlocked, and the shield segments are constructed. The tunnel is like a "body armor" that protects it. It has high standard of compression, impermeability and seismic performance. It can provide safe space and guarantee for the vehicles flying in the tunnel, which can effectively improve the urban traffic conditions.
Since 2016, the tube factory has completed all the production tasks of the Changsha Metro Lines 3, 4 and 5, and began to supply the Changsha Metro Line 6, Wanjiali Power Tunnel and other project segments. The comprehensive strength of the segment is the first in Hunan, and CCT Technology will continue to provide high-quality projects for the country and expand the space for the people to enjoy happiness.” Peng Yizhou, general manager of China Construction Technology Hunan Co., Ltd. said.
Innovation, coordination, green, openness, sharing, Ningxiang Economic Development Zone leveraged innovation and development, successfully let the five development concepts step into the reality step by step in the park, and a “smart manufacturing” Dongfeng is blowing to every corner of the park. As the "industry platform" and "technology platform" for the new-type construction industrialization of the joint-stock company, Zhongjian Technology Hunan Co., Ltd. currently operates a total contracting capacity of 200,000 cubic meters of concrete components and 1 million square meters of building-area assembled buildings. With an annual output of 30,000 ring subway segments, the company's industrialization base is making full efforts to create a green building ecosystem with green construction and green demolition, which will lead the future development of the building.
