Steel corrugated culvert pipe, prefabricated corrugated culvert pipe construction technology

The prefabricated steel corrugated culvert is characterized by its robustness, lightweight design, and efficiency in handling storage and transportation. It simplifies the construction process with its rapid assembly and short construction timeline. To mitigate frost heave damage in cold climates and uneven foundation settlement in warmer areas, both the inner and outer surfaces of the corrugated pipe sections, along with the fastening bolts, undergo hot-dip galvanization before leaving the factory, ensuring longevity against rust. The galvanized layer's thickness is maintained at a minimum of 63µm, with an average of 84µm; additionally, an asphalt coating enhances its protective measures during installation, promising a service life of up to 100 years.

Understanding the Technology Behind Corrugated Steel Pipelines

The corrugated steel pipe (plate) culvert capitalizes on the interaction between the pipe's body and the surrounding backfill soil, forming a crucial pipe-soil effect. The relation between the two is essential; should the surrounding backfill soil provide insufficient or uneven reaction forces, it could result in deformation of the corrugated steel plate beyond acceptable limits.

The Construction Process

The steps involved in construction include:

1. Excavation
2. Construction layout
3. Foundation cushion filling
4. Pipe installation
5. Culvert backfill
6. Opening paving

Digging the Base

In cases where design specifications are provided, the foundation must be excavated accordingly. For scenarios lacking specific design criteria, reference tables can be utilized to determine proper cushion thicknesses and trench widths to facilitate effective mechanical rolling.

Further Considerations

Upon completion, ensuring adherence to the aforementioned guidelines requires meticulous planning and execution. Experienced engineers may share insights to reinforce best practices and guidelines during construction operations. Consultations with reliable references and studies further bolster confidence in the approaches adopted.

Conclusion

In summary, utilizing a combination of prefabricated steel components for culvert construction optimizes strength, stability, and longevity. The methodologies presented play a significant role in the successful execution of projects, warranting adherence to proposed standards.
