On December 2, MCC organized a scientific and technological achievements evaluation meeting in Chengdu, in which five scientific and technological achievements completed by MCC5 were evaluated as international advanced level or domestic leading level. The mechanism of unloading deformation and fine control technology of high stress soft rock tunnels, key technology of dry quenching coke oven longevity and high efficiency repair, key technology of construction, operation and maintenance of waste transfer station for future cities, and precise construction technology of Möbius ring building curtain wall and bamboo steel roofing have reached the international advanced level as a whole. The complete set of near-zero energy building design, construction, intelligent operation and maintenance technology reached the domestic leading level. Curtain Wall and Bamboo Steel Roof Precision Construction Technology reached the international advanced level, and the complete set of near-zero energy building design and construction and intelligent operation and maintenance technology reached the domestic leading level, further demonstrating the company's scientific research strength and innovation ability. The complete set of near-zero energy building design, construction, intelligent operation and maintenance technologies has reached the domestic leading level, further demonstrating the company's scientific research strength and innovation ability.

The mechanism of unloading deformation and fine control technology of high stress soft rock tunnels aims at the technical problems of large deformation in high stress soft rock tunnels, the scientific and technological achievements have been developed through years of joint research and development between the industry, academia and research institutes, resulting in a refined design method that takes multiple factors into consideration, and a series of active support technologies, which have been applied and promoted in many railway and highway tunnelling projects. Among them, the quantitative characterization of the deterioration process of the mechanical properties of surrounding rock in high stress soft rock tunnels and the analysis method considering the deterioration of the mechanical properties of unloading surrounding rock have reached the international leading level, which has laid a foundation for the company in the investigation, design and construction of soft rock tunnels.

Dry quenching coke oven longevity and high efficiency repair technology takes the low carbon and green restoration technology of dry quenching coke oven as the research direction, and have developed the long-life flower refractory castable reinforcement technology, the assembly process of dry quenching coke oven restoration and the fast and high-precision restoration technology. With the aid of developing the integrated digital management platform and the Internet cloud technology, breakthroughs have been made in the key technological difficulties of dry quenching coke ovens in terms of their longevity. Among them, ‘in-situ generation of AIlN whisker toughening technology for mullite-silicon carbide castables’ has reached the international leading level.

The scientific and technological achievements of Construction, operation and maintenance of waste transfer station for future cities introduced the multi-functional integration design concepts of waste transfer, urban park and human defence, formed an integrated synergistic design method above and below ground, effectively solved the construction problems of waste transfer stations in park cities, and provided a new direction for the company to cultivate new quality productivity and business development.

The precise construction technology of Möbius ring building curtain wall and bamboo steel roofing takes the intelligent design, processing and installation of Möbius ring-shaped architectural curtain wall and bamboo steel roofing as the direction. Based on the refined model reconstruction method of laser scanning technology, it has formed the parametric numerical control machining method of complex components, and researched and developed the cross-frame-free support device for large tilted and twisted glass curtain wall. The precise splicing device of ultra-long twisted aluminium panel grille, and the expandable and retractable device of twisted bamboo steel roofing have realized the precise construction of Möbius ring-shaped architectural curtain wall and bamboo steel roofing. It provides technical support for the company to develop the business of decorative decoration of shaped curved buildings.
