How to Solve Transportation Challenges for Super-Large UHPC Shapes—A Discussion of Technical Innovation and Engineering Practice

In the field of contemporary architectural decoration, UHPC has become a core material for shaping landmark buildings thanks to its outstanding mechanical properties and expressive formability. However, the transportation of super-large UHPC components has always been a key bottleneck restricting project implementation. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group has built a systematic solution spanning from detailed design to transportation and delivery through technological innovation and engineering practice, providing a professional model for the efficient realization of super-large UHPC forms.

I. Industry Pain Points and Technical Challenges in Super-Large UHPC Transportation

Super-large UHPC components typically feature large dimensions, irregular curved surfaces, and high precision, and their transportation faces multiple challenges: on the one hand, traditional transportation methods can easily cause cracking and surface damage to components, affecting installation accuracy and aesthetics; on the other hand, the approval process for over-limit transportation is complex and may delay project schedules. Take the UHPC curtain wall of a commercial complex as an example: a single component measures 6m×3m and weighs over 2 tons, and the fixing method of traditional flatbed trucks can hardly meet seismic and stability requirements. In addition, temperature and humidity changes during transportation may also cause fluctuations in material performance, posing a potential threat to the durability of UHPC.

II. Qinglong Group's Technological Innovation: From Design Optimization to Customized Transportation Solutions

To address the transportation challenges of super-large UHPC, Qinglong Group has leveraged the technical strength of its national-level R&D center to form an integrated innovation system of "design-production-transportation". At the detailed design stage, BIM technology and parametric modeling are used to break down complex forms into modular components, which both ensures the design effect and reduces transportation difficulty. For example, the hyperbolic UHPC ceiling of a grand theater was divided into 12 splicable units, each weighing within 1.5 tons, greatly improving transportation flexibility.

For transportation solutions, Qinglong Group has developed dedicated hydraulic lifting transport frames, combined with flexible cushioning materials and intelligent reinforcement systems, to achieve stable three-dimensional attitude control of components. Meanwhile, real-time monitoring systems collect and analyze vibration, temperature, and humidity data during transportation to ensure that component performance remains unaffected. This "customized transportation solution + intelligent monitoring" model has been successfully applied to multiple large projects such as the Century Plaza renovation project on Nanjing East Road, keeping the transportation damage rate below 0.5%.

III. Full-Chain Coordination and Quality Assurance in Engineering Practice

As a comprehensive service provider integrating detailed design, manufacturing, and construction installation, Qinglong Group emphasizes the coordination between the transportation phase and preceding and following processes. In the production stage, a "local production" strategy is adopted, relying on the production base in Nanning, Guangxi and a nationwide office network to reduce long-distance transportation risks; before installation, 3D laser scanning technology is used for pre-assembly simulation of components, ensuring rapid and precise installation once they arrive on site. In addition, the company has established a comprehensive quality traceability system, with each UHPC component equipped with a unique identifier, and full-process data from raw materials to transportation and delivery being traceable, providing solid assurance for project quality.

IV. Industry Value and Future Outlook

The transportation solution for super-large UHPC forms not only reflects Qinglong Group's technical accumulation in the field of new architectural decoration materials, but also drives the upgrading of industry standards. As a participating developer of the industry standard "General Technical Conditions for Non-Load-Bearing Components of Ultra-High Performance Concrete (UHPC)", Qinglong Group will continue to explore material performance optimization and logistics technology innovation, providing designers and owners with more imaginative paths to architectural realization. In the future, with the development of modular construction and intelligent logistics technologies, the transportation efficiency and safety of UHPC materials will be further improved, injecting more possibilities into the mission of "creating beautiful architecture".

From landmark buildings to commercial spaces, the transportation challenges of super-large UHPC forms are being solved by systematic technical solutions. With 28 years of industry experience as its foundation, Qinglong Group, through design optimization, technological innovation, and full-chain coordination, brings the architectural dreams of complex forms into reality, demonstrating the core value of new decorative building material enterprises in driving industry progress.
