5.5-meter diameter custom-shaped steel corrugated pipe construction

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

Secondly, 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 excellent integrity and plasticity contribute to strong resistance to deformation in complex geological road sections.

Five, its good 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, with a processing thickness of 1.6mm to 7mm, capable of meeting the requirements for structures with a pipe top backfill height of 0.5m to 60m. Wall thickness: refers to the thickness of the steel plate forming the pipe wall.

Degrees, 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: 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 support a fill height 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 8-section wall and sloping entrance as shown in the right figure. Slope opening: Due to the culvert and...

Road intersection angles not 90 degrees, requiring special angle culverts. Culvert entrance and exit with sloping openings, necessitating special angle culverts.
