In bridge construction, the tie beam is like the “skeleton” of the human body, playing a key role in connecting the pile foundation and the pier body and dispersing the load. The high-precision and high-strength steel formwork directly determines the quality and efficiency of the tie beam casting. Recently, the parent company of Pansol Steel Formwork has successfully applied its independently developed customized tie beam formwork to the Huaihe River Bridge project, helping the construction team to complete the precise casting of a single tie beam in a very short time, significantly improving efficiency compared with traditional processes. What are the technical highlights behind this achievement

Construction Challenges of the Huaihe River Bridge: Why is the tie beam formwork so critical?

The Huaihe River Bridge crosses a complex hydrogeological zone, and the tie beam design must meet the three stringent requirements of high strength, large volume and high precision. Traditional wooden formwork or general steel formwork is prone to deformation, joint leakage, and it is difficult to meet high-standard construction requirements.

The customized design of Pansol steel formwork directly hits these pain points:

1. The “tailor-made” design uses BIM modeling and CNC cutting technology to ensure that the formwork and the steel cage are fully matched, avoiding secondary repairs on site.
2. The national standard steel + reinforced rib panel uses Q235b steel plate with a compressive strength of 50MPa to ensure that there is no risk of mold expansion during the pouring process.
3. The modular bolt connection design of the “quick disassembly and quick assembly” system allows 6 workers to complete the assembly in just 2 hours, saving about 60% of the working hours compared to the traditional welding process.
   

Industry enlightenment: How does steel formwork reshape the bridge construction standard?

It is estimated that the turnover of Pansol tie beam formwork can reach more than 50 times, and the comprehensive cost is about 35% lower than that of traditional wooden formwork. The chief engineer of the Huaihe Bridge project commented: “High precision and zero rework are the real hard power of ‘reducing costs and increasing efficiency’.” With the popularization of prefabricated buildings, customized steel formwork is becoming the mainstream choice for large-scale infrastructure projects. Pansol’s technical practice not only accelerated the construction of the Huaihe River Bridge, but also provided a replicable quality control sample for the industry. From blueprint to reality, every step of bridge construction is a race against time. Pansol steel formwork, with its “millimeter-level” rigor, explains how “Made in China” can empower super projects.
