As a key cross-river transportation hub project in Anhui Province, the G3 Tongling Yangtze River Rail-cum-Road Bridge requires extremely high standards for concrete durability, structural strength, and impact resistance. Supported by CO-NELE UHPC Ultra-High Performance Concrete Mixing Plant, the project overcomes the performance shortcomings of traditional concrete and realizes the mass production of high-precision and high-stability UHPC materials. It successfully completed the pouring of the first section of UHPC pavement on the main bridge’s highway deck, effectively improving construction quality and efficiency, shortening the construction period, and reducing construction costs. This case provides a mature UHPC mixing equipment application solution for large-scale cross-river bridge infrastructure projects.

Project Background: Construction Pain Points of Concrete for Large-Scale Cross-River Bridges
The G3 Tongling Yangtze River Rail-cum-Road Bridge is a key infrastructure project in Anhui Province. Spanning the main waterway of the Yangtze River, it features a large bridge span and complex structural working conditions. Subject to long-term river erosion, wind load, and alternating stress, the bridge imposes stringent requirements on the comprehensive performance of building materials. Conventional ordinary concrete suffers from insufficient strength, poor durability, weak impact resistance, and limited service life, failing to meet the long-term safe operation requirements of large-span rail-cum-road bridges.
To meet the project’s core construction standards of long-term durability, ultra-high strength, strong impact resistance and high stability, the project team adopted UHPC (Ultra-High Performance Concrete) as the core paving and structural material. Compared with traditional concrete, UHPC boasts ultra-high compressive strength, excellent toughness, superior impermeability and corrosion resistance, and outstanding fatigue resistance, making it the preferred material for high-end bridges and major infrastructure projects.
However, UHPC features precise proportioning requirements and high technical barriers for mixing, demanding extremely high intelligence accuracy and stability of construction equipment. Ordinary mixing equipment is prone to proportioning deviation, uneven material mixing, and unstable batch quality, which directly affects project quality. After multiple rounds of technical comparison and equipment screening, the project finally selected CO-NELE professional UHPC mixing plant. It relies on mature high-strength concrete mixing technology and intelligent control systems to ensure the mass production quality of UHPC materials.

Project Achievements: Multi-dimensional Breakthroughs in Quality Improvement, Efficiency Enhancement and Cost Reduction
The application of CO-NELE UHPC mixing plant in the Tongling Yangtze River Rail-cum-Road Bridge project has successfully solved the core challenges of UHPC construction for high-end bridges, delivering remarkable results and empowering the high-quality construction of the project in all aspects:
First, strictly control project quality and ensure smooth construction. It stably supplies high-performance and highly consistent UHPC concrete materials that fully meet the construction standards of bridge deck pavement and main structure. The equipment successfully supported the pouring of the first UHPC pavement section on the main highway deck of G3 Tongling Yangtze River Rail-cum-Road Bridge, laying a solid quality foundation for subsequent large-scale construction.
Second, improve production efficiency and shorten the project schedule. The intelligent mixing equipment features high automation and stable mass production efficiency, which greatly reduces manual intervention and material loss. It significantly improves the production efficiency of UHPC concrete and shortens the overall construction cycle, accelerating the efficient progress of key infrastructure projects.
Third, optimize construction costs and improve project benefits. Precise proportioning reduces raw material waste, and stable material quality lowers rework, maintenance and repair costs in the later stage. It comprehensively controls the overall project cost from production, construction and operation dimensions, achieving dual improvement in quality and cost performance.
