Corrugated steel culvert (HSDG) is a highway construction material that can replace circular culverts, cover culverts, box culverts, arch culverts, and small bridges, and is used for road-rail transverse passages and embankments.

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

Two, Steel corrugated pipe offers significant economic benefits in frozen soil areas and soft soil subgrade regions.

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

Four, its good integrity and plasticity provide strong resistance to deformation in road sections with complex geological conditions.

V. Its excellent thermal conductivity causes minimal disturbance to the subgrade in frozen soil areas, ensuring subgrade stability.

Steel corrugated pipe products are available in two structural types: assembled and prefabricated. The 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 ranging from 1.6mm to 7mm, capable of meeting the requirements for structures with a pipe top 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, while for 200-55 wave patterns, 3-8mm steel plate can be utilized. Diameter: refers to the inner diameter of the bellows.

Backfill Height: The fill height that a specific model of corrugated pipe can accommodate, for example, a 200-55 corrugated pipe with a wall thickness of 4.5mm can handle 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 needs to be increased by methods such as increasing wall thickness.

Load capacity. Within the permitted backfill area, vehicles with a capacity of 120 tons can pass through. Tunnel Entrance Design: Bamu wall, slope tunnel entrance as shown in the right figure. Slope opening: due to the culvert...

Special angle culverts required as the road intersection is not 90 degrees. Slope: Since the culvert's inlets and outlets are designed with sloping openings, special angles are necessary.
