Introduction
Single box double cells segmental box girder formwork refers to a segmental box girder formwork that is divided into two independent cells in a box-shaped section.
Applicable fields: Single-box double-cell segment box girders are suitable for medium-span or large-span bridge projects, especially bridges that require higher lateral bearing capacity and stability, such as wide bridges, curved bridges, and cable-stayed bridges. Its characteristics of convenient construction and fast speed also make it suitable for bridge projects that require construction period.
Technical Parameters

1. Energy conservation and environmental protection: By using precast assembly methods can reduce environmental pollution such as waste and noise caused by on-site construction while saving materials and energy.
2. Stronger load-bearing capacity: The two symmetrical beam cells, the single-box double-cell segmental box girder has better lateral load-bearing capacity and stability.
3. Suitable for large-span bridges: Single-box double-cell segment box girders are suitable for large-span and large-load bridges and can meet the needs of large-scale transportation infrastructure.
4. High Flexibility: Because it is a precast structure, the assembly and combination of single box double cell segment box girder has high flexibility and can adapt to different construction environments and conditions.
Q1: How to properly install and remove single box double cells segmental box girder formwork?
When installing the formwork, it must be carried out in accordance with the construction drawings and relevant specifications to ensure accurate positioning and angles. It usually requires the use of lifting equipment for installation. When disassembling the formwork, proceed in the reverse order of installation and ensure that the formwork is securely placed in the designated location.
Q2. How to ensure the accuracy of single box double cells segment box girder formwork?
The accuracy of the single-box double-chamber segment box girder formwork is guaranteed through advanced manufacturing equipment and processes, as well as strict testing and correction procedures.
