Corrugated steel culvert (HSDG) is a highway construction material that can replace round culverts, slab culverts, box culverts, arch culverts, and small bridges, and is used 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, just ensure the inner wall is well-protected and maintained.

Two, Steel corrugated culvert pipes offer 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 contribute to strong resistance against deformation in complex geological road sections.

Five, its good thermal conductivity results in minimal disturbance to the subgrade in frozen soil areas, ensuring stability.

Steel corrugated pipe products are available in assembled and prefabricated structures; cross-sectional shapes include circular, elliptical, horseshoe, arch, and more. 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 structural heights of 0.5m to 60m for pipe-top backfill. Wall thickness: refers to the thickness of the steel plate forming the pipe wall.

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

Filling Height: The maximum 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 support a fill height of d2 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, additional measures such as increasing wall thickness are required to enhance bearing capacity.

Load capacity. Vehicles up to 120 tons can pass through the allowed backfill area. Tunnel entrance design:八卦墙, sloping tunnel 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 use of sloping entrance and exit openings for the culvert, a special angle is needed.
