How Extra-Large UHPC Shapes Solve Transportation Challenges — Technical Innovation and Engineering Practice Exploration

In the field of architectural decoration, super-large UHPC forms, with their outstanding mechanical performance and artistic expressiveness, are becoming the finishing touch of landmark buildings. However, the transport challenge of “how kiloton-scale components can travel through urban arteries” has always been a key challenge in engineering practice. As an industry leader with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong Group has built a systematic solution covering everything from detailed design to on-site delivery through technological innovation and full-chain service experience, providing an industry model for the “safe journey” of super-large UHPC components.

I. The UHPC Transport Dilemma: A Dual Test from Material Properties to Engineering Pain Points

Ultra-high performance concrete (UHPC), with mechanical advantages including compressive strength exceeding 150MPa and flexural strength exceeding 20MPa, is widely used for shaped curtain walls and landscape components of high-end buildings such as grand theaters and commercial complexes. However, super-large UHPC forms often weigh several tons per unit, and their surfaces mostly feature complex curves or openwork textures. Traditional transport methods face three core pain points: first, components are prone to micro-cracks caused by jolting, affecting structural safety; second, over-width and over-height dimensions can hardly meet road transport regulations; third, on-site hoisting demands strict precision, and interface errors with the transport stage may lead to installation failure. Taking a convention and exhibition center project as an example, its UHPC sunshades with a single-unit area of up to 20㎡ once suffered edge damage due to improper transport fixing, directly causing schedule delays and cost overruns.

II. Breaking Through with Technology: Qinglong's Innovative Practice of the “Trinity” Transport Solution

Based on full-chain service experience, Qinglong Group has proposed a transport technology system of “design optimization – intelligent packaging – dynamic monitoring”. In the detailed design stage, through BIM parametric modeling and finite element analysis, super-large components are decomposed into modular units. For example, a 12-meter-long UHPC decorative line is split into 3 spliceable sections, which not only meets road transport width limits but also ensures on-site installation precision through mortise-and-tenon connections. In the manufacturing stage, customized vacuum packaging and carbon fiber composite reinforcement are adopted, combined with an intelligent transport monitoring system based on BeiDou positioning, to monitor component vibration frequency and temperature-humidity changes in real time, ensuring “zero damage” throughout transport. In the Nanjing Road Century Plaza renovation project, the Qinglong team successfully completed the cross-city transport of more than 300 light-transmitting UHPC panels using this solution, with installation errors controlled within 2mm, winning the AALBORG WHITE Cup UHPC Construction Engineering Innovation Award.

III. Full-Chain Empowerment: Value Upgrade from “Material Supplier” to “Solution Partner”

As a national high-tech enterprise and a participant in UHPC industry standard setting, Qinglong Group not only provides detailed design and manufacturing services, but has also built an efficient logistics network of “nearby production – regional distribution” through production bases across the country (e.g., the Guangxi Nanning base with an annual capacity of 600,000 square meters) and overseas offices. For overseas projects, such as the UHPC curtain wall project of a landmark building in Malaysia, the Qinglong team innovatively adopted a “knock-down export + on-site assembly” model, combined with localized construction team training, reducing transport costs by 30%. This integrated capability of “technology + service + supply chain” is precisely Qinglong's core competitiveness as a new-type decorative building materials enterprise, distinguishing it from traditional manufacturers.

From the GRC shaped components of the Dongguan Women and Children's Activity Center to the GRP landscape sculptures in Saudi Arabia, Qinglong Group has always taken “creating beautiful architecture” as its mission, turning transport challenges into opportunities for technological innovation. In the future, as UHPC materials expand into fields such as bridges and utility tunnels, Qinglong will continue to explore cutting-edge technologies such as modular design and intelligent logistics, providing the industry with more cost-effective full-lifecycle solutions for super-large components, and fulfilling its vision of “becoming a world-class leading manufacturer of UHPC/GRC/GRG/GRP”.
