Corrugated steel culvert (HSDG) is a highway construction material that replaces round culverts, cover culverts, box culverts, arch culverts, and small bridges, and is suitable for highway-rail cross passages and embankments.

In projects involving roads, culverts, drainage pipes, and shelters, etc. Advantages of corrugated culvert (sheet): 1. Easy to maintain, just ensure proper protection and maintenance of the inner wall.

Secondly, steel corrugated pipe offers significant economic benefits in frozen soil regions and soft soil roadbed areas.

Three, steel corrugated pipe has been treated for corrosion resistance and boasts high durability.

Four, its excellent integrity and plasticity offer strong resistance to deformation in complex geological conditions.

V. Its good thermal conductivity results in minimal disturbance to the subgrade in frozen soil areas, ensuring stability of the subgrade.

Steel corrugated pipe products are available in two structural types: assembled and prefabricated; cross-sectional shapes include circular, elliptical, horseshoe, and arch shapes, etc. The pipe diameter range is 0.3m.

—12m in length, with a processing thickness of 1.6mm to 7mm, capable of meeting the requirements for structures with a pipe crown fill height of 0.5m to 60m. Wall thickness: refers to the thickness of the steel plate forming the pipe wall.

Dimensions: Generally, for 125-25 wave patterns, 3-Smm steel plate is used; for 200-55 wave patterns, 3-8mm steel plate can be utilized. Diameter: refers to the inner diameter of the corrugated pipe.

Filling Height: The maximum height of backfill that a specific model of corrugated pipe can accommodate, e.g., a 200-55 corrugated pipe with a wall thickness of 4.5mm can support a fill height of 2 meters.

Backfill height: 0.6-33 meters, meaning the backfill thickness on the pipe is 0.6 meters, and the total backfill thickness is 33 meters. If exceeding 33 meters, the load-bearing capacity can be increased by methods such as increasing the wall thickness.

Load capacity. Up to 120-ton vehicles can pass through the 8-square wall slope entrance within the permitted backfill area. Slope entrance as shown in the right figure. Slope opening: due to the culvert...

Special angle culverts required as the road intersection is not at a 90-degree angle. Slope from: Due to the culvert's inlets and outlets using sloped openings, a special angle needs to be made.
