The advantages of steel corrugated culverts mainly include the following aspects:
Strong ability to adapt to foundation deformation: Steel corrugated culverts have a certain flexibility and can adapt to uneven settlement and deformation of the foundation, effectively solving the problem of culvert damage caused by uneven settlement of the foundation. Its unique corrugated structure allows both axial and radial stress strain to be borne, giving better play to the advantages of steel structure.
Fast construction speed: The installation of steel corrugated culverts mainly depends on the assembly of pipe sections, which reduces the time for concrete pouring and maintenance. For example, a cover culvert requires 65 days of construction, while a steel corrugated culvert only requires 31 days, saving half of the construction period. In addition, it is easy to install on site and does not require large equipment, further shortening the construction period.
Cost saving: The cost of steel corrugated culverts is relatively low, especially when the pipe diameter is greater than 2.5 meters, its cost is significantly lower than that of masonry structure culverts, with a reduction of 10%~30%. Factory centralized production is also conducive to reducing costs and controlling quality.
High driving comfort: The backfill design of the steel corrugated pipe culvert adopts a gradual filling width, which can effectively reduce the backfill settlement, significantly improve the "misaligned platform jumping" phenomenon, and improve driving comfort and safety.
Excellent environmental performance: The steel corrugated pipe culvert does not require a large amount of sand, stone, cement and other materials during the manufacturing process, which reduces the generation of construction waste and has significant environmental and social benefits.
Strong durability: The service life of the steel corrugated pipe culvert after galvanizing anti-corrosion treatment can reach more than 50 years, reducing the frequency of maintenance and replacement.
