Highway Metal Corrugated Pipe

Corrugated pipe (sheet) advantages: 1. Easy to maintain, simply ensure the inner wall is well-protected and maintained.

Section II: Steel corrugated pipe offers significant economic benefits in areas with frozen soil and soft soil roadbeds.

Three, steel corrugated pipe has undergone corrosion treatment and boasts high durability.

Four: Its good integrity and plasticity provide strong resistance to deformation on road sections with complex geological conditions.

Five, 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; cross-sectional shapes include circular, elliptical, horseshoe, and arch, 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 backfill height from 0.5m to 60m. Wall thickness: refers to the thickness of the steel plate forming the pipe wall.

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

Backfill Height: The height of backfill 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 the backfill height requirement of d2 meters.

Soil 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.

Power. Vehicles weighing up to 120 tons can pass through the allowed backfill area with a width of k meters. Tunnel Entrance Design: The eight-character wall, as shown in the right figure. Slope Entrance: Due to the culvert and...

Special angle culverts required as the road intersection is not 90 degrees. Slope culvert: Due to the inclined entrance and exit of the culvert, special angle culverts are needed.
