Corrugated steel culvert (HSDG) is a highway construction material that serves as an alternative to circular culverts, slab culverts, box culverts, arch culverts, and small bridges, and is suitable for highway-railway transverse passages and embankments.
In projects involving roads, culverts, drainage pipes, and shelters, etc. Advantages of corrugated culvert (sheet): 1. Easy to maintain, simply by ensuring the protection and maintenance of the inner wall.
Two, steel corrugated pipe offers significant economic benefits in frozen soil regions and soft soil roadbed areas.
Three, the steel corrugated pipe has been treated for corrosion resistance, offering high durability.
Four, its excellent integrity and plasticity contribute to strong resistance against deformation in complex geological conditions.
Five, its excellent thermal conductivity results in minimal disturbance to the subgrade in frozen soil areas, ensuring subgrade stability.
Steel corrugated pipe products are available in assembled and prefabricated types; cross-sectional shapes include circular, elliptical, horseshoe, and arch shapes, etc. The pipe diameter range is 0.3m.
—12m, with a processing thickness of 1.6mm to 7mm, capable of meeting the requirements for structures with a pipe top backfill height of 0.5m to 60m. Wall thickness: refers to the thickness of the steel plate of the pipe wall.
Degree, generally use 3-Smm steel plate for 125-25 wave patterns, and 3-8mm steel plate for 200-55 wave patterns. Diameter: refers to the inner diameter of the corrugated pipe.
The backfill height for a specific model of corrugated culvert, for instance, a 200-55 corrugated culvert with a wall thickness of 4.5mm, can accommodate a backfill height of 2 meters.
Backfill height: 0.6-33 meters, meaning the backfill thickness on the pipe is 0.6 meters, and the backfill thickness is 33 meters. If exceeding 33 meters, it requires increasing the wall thickness or other methods to enhance the bearing capacity.
Load capacity. Within the permitted backfill area, vehicles up to 120 tons can pass through. Tunnel opening design: as shown in the right figure, slope tunnel opening. Slope opening: due to the culvert...
Special angle culverts required when the road intersection is not 90 degrees. Slope from: Due to the oblique entrance and exit of the culvert, a special angle is needed.
