Culvert bridge drainage corrugated pipe culvert

Corrugated steel plate culverts (HSDG) are a substitute for round tube culverts, box culverts, arch culverts, and small bridges, serving as highway construction materials. They are suitable for highway-rail cross passages and embankments.

In projects such as roads, tunnels, drainage pipes, and shelters. Advantages of corrugated pipe (sheet): 1. Easy to maintain, requiring only the protection and maintenance of the inner wall.

Section 2: Steel corrugated pipe offers significant economic benefits in frozen soil regions and soft soil subgrade areas.

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

Four, its good integrity and plasticity enable strong resistance to deformation on complex geological condition road sections.

V. 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 two structural types: assembled and prefabricated; with cross-sectional shapes including circular, elliptical, horseshoe, and arch, etc. The pipe diameter range is from 0.3m.

—12m, with processing thickness ranging from 1.6mm to 7mm, capable of meeting the requirements for structures with pipe crown backfill heights from 0.5m to 60m. Wall thickness: refers to the thickness of the steel plate forming the pipe wall.

Degrees, general 125-25 wave patterns use 3-Smm steel plates, while 200-55 wave patterns can use 3-8mm steel plates. Diameter: refers to the inner diameter of the corrugated tube.

Filling 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 meet 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, the load-bearing capacity must be increased by methods such as increasing the wall thickness.

Load capacity. Vehicles up to 120 tons can pass through the allowed backfill area. Tunnel Entrance Design: Baozi wall, sloping tunnel entrance as shown in the right figure. Slope opening: due to the culvert...

Special angle culverts required where the road intersection is not 90 degrees. Slope: Due to the use of sloped inlets and outlets for the culvert, a special angle is necessary.
