Hollow corrugated pipe

Wavy steel plate culverts (HSDG) are a substitute for circular pipe culverts, slab culverts, box culverts, arch culverts, and small bridges as highway construction materials. They are suitable for highway-railway transverse passages and embankments.

In channels, culverts, drainage pipes, and shelters, etc. Advantages of corrugated pipe (sheet): 1. Easy maintenance, just ensure the inner wall's protective maintenance.

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

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

Four, its good integrity and plasticity enable strong resistance to deformation in complex geological conditions.

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 integral and assembled types; cross-sectional shapes include circular, elliptical, horseshoe, arch, etc. The pipe diameter range is 0.3m.

—12m, with processing thickness ranging from 1.6mm to 7mm, capable of meeting the requirements for structures with a pipe crown fill height from 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.

Backfill Height: Refers to the maximum fill height that a certain model of corrugated pipe can accommodate, for instance, a 200-55 corrugated pipe with a wall thickness of 4.5mm can support a backfill height of 2 meters.

Filling height: 0.6-33 meters, meaning the soil thickness on the pipe is 0.6 meters, and the soil thickness is 33 meters. If exceeding 33 meters, the load-bearing capacity needs to be increased by methods such as increasing the wall thickness.

Load-bearing capacity. Vehicles weighing up to 120 tons can pass through the allowed backfill area. Tunnel Entrance: The design is as shown in the right figure. Slope entrance: Due to the culvert...

Special angle culverts required where the road intersection is not 90 degrees. Slope from: Due to the oblique entrance and exit of the culvert, a special angle is needed.
