Application of Steel Formwork in the Chengdu Tianfu Avenue–Yangma Bridge Expansion – Chengdu, China (2023–2024)

Project Name: Chengdu Tianfu Avenue–Yangma Bridge Expansion Project
Location: Chengdu, Sichuan Province, China
Project Time: March 2023 – January 2024

Overview

In 2023, Chengdu launched the Tianfu Avenue–Yangma Bridge Expansion Project—a key initiative to improve connectivity in the southern urban area. This infrastructure project involved constructing additional bridge decks and widening the existing span. Due to the complexity of large-scale concrete pours and the necessity for high accuracy, the contractor opted for steel formwork as the primary solution.

Zhuozhan Solution

Zhuozhan provided a customized steel formwork system designed for bridge applications. The solution included:

High-strength modular panels for piers, deck slabs, and wingwalls.

Precision engineering support, ensuring accurate alignment for large-span structures.

Onsite technical guidance, helping the contractor improve assembly efficiency.

Surface treatment on the formwork panels, extending their lifecycle and performance under Chengdu’s humid climate.

This tailored solution not only addressed the project’s safety and efficiency requirements but also optimized cost-effectiveness through reusable and durable components.

Key Advantages

Strength & Stability: Designed to support large-volume concrete pours with minimal deformation.

High Precision: Delivered accurate alignment and a smooth exposed concrete surface finish.

Durability: Reusable through multiple bridge segments, minimizing lifecycle costs.

Weather Resilience: Maintained performance in Chengdu’s rainy conditions.

Efficiency: Modular design allowed for fast assembly/disassembly, accelerating the work schedule.

Construction Application

Bridge Piers: Heavy-duty steel formwork supported tall, high-load-bearing bridge columns.

Deck Slabs: Ensured perfectly flat, smooth deck surfaces for the widened roadway.

Wingwalls & Abutments: Steel panels maintained exact alignment and provided robust formwork for new abutment sections.

Results & Feedback

By January 2024, the expanded bridge was completed on time, improving traffic flow and network connectivity in southern Chengdu. The use of Zhuozhan steel formwork significantly reduced labor intensity, shortened construction cycles, and lowered material wastage compared to traditional timber methods.

Client Feedback
Mr. Zhang, Project Director of the Chengdu Tianfu Avenue–Yangma Bridge Expansion, commented:

“Zhuozhan’s steel formwork system provided the reliability and efficiency we needed for this complex project. Their customized solution and technical support ensured precise alignment and excellent concrete finishes. The reusable panels not only saved us costs but also improved construction speed. We are very satisfied with the performance and will continue to consider Zhuozhan in future infrastructure projects.”

The Chengdu Municipal Transportation Bureau also commended the high-quality concrete finish, which reduced the need for additional surface treatments and offered excellent long-term durability.
