Do UHPC Manufacturers Have Many Cooperation Cases on Bridge Projects?

As the application of UHPC in bridge engineering becomes increasingly widespread, a manufacturer's project experience in the bridge sector has become an important indicator of its technical strength. Qinglong Group has accumulated extensive experience in bridge UHPC applications, having participated in numerous renovation and new construction projects for pedestrian bridges and highway bridges.

In the field of pedestrian bridges, UHPC is widely used for its excellent mechanical properties and durability. Qinglong Group participated in a landscape pedestrian bridge project in a city, using UHPC for the main girder structure to achieve a 35-meter span without intermediate supports. This lightweight, high-strength characteristic greatly reduced the amount of foundation work and shortened the construction period. The bridge deck features an anti-slip textured design, with a surface wear rate below 0.1mm per year, demonstrating outstanding durability.

In the field of highway bridge deck paving, UHPC demonstrates significant advantages. In a highway bridge deck renovation project that Qinglong Group participated in, a 30mm thick UHPC paving layer was used, with a projected service life of up to 100 years. Compared with conventional concrete, the impermeability of UHPC paving is improved by two orders of magnitude, effectively preventing de-icing salt corrosion of the bridge deck. This application provides a new solution for long-life bridge design.

UHPC also demonstrates unique value in the repair of bridge joints. The specialized repair material developed by Qinglong Group has a compressive strength of up to 150MPa and can reach the strength required for opening to traffic within 24 hours. In the maintenance project of a river-crossing bridge, UHPC was used for joint repair, shortening the repair period from the traditional 14 days to 3 days, greatly reducing the impact on traffic.

Although Qinglong Group has multiple successful cases in the bridge sector, compared with the architectural decoration field, the application of UHPC in bridges is still at a developing stage. With the improvement of relevant standards and the accumulation of engineering practice, the application prospects of UHPC in bridge engineering will become even broader.
