Non-standard metal bellows

Wavy culvert (sheet) advantages: 1. Easy maintenance, just ensure proper protection and maintenance of the inner wall.

Section II: 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 and boasts high durability.

Four: Its excellent integrity and malleability offer 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, with processing thickness ranging from 1.6mm to 7mm, capable of meeting the requirements for structures with pipe top backfill heights from 0.5m to 60m. Wall thickness: refers to the thickness of the steel plate of the pipe wall.

Diameter: refers to the inner diameter of the bellows. For a 125-25 wave pattern, generally use 3-Smm steel plates; for a 200-55 wave pattern, 3-8mm steel plates can be used.

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 support backfill up to d2 meters.

Earth height: 0.6-33 meters, meaning the earth fill thickness on the pipe is 0.6 meters, and the total fill thickness is 33 meters. If exceeding 33 meters, the load-bearing capacity can be increased by increasing the wall thickness or other methods.

Power. Within the permitted backfill area, vehicles up to 120 tons can pass through. Tunnel Entrance: The tunnel entrance is designed as a Chinese character wall, as shown in the right figure. Slope Entrance: Due to the culvert and...

Road junction angles not at 90 degrees, requiring special angle culverts. Slope inlets: Due to the slope openings of the culvert's inlets and outlets, special angle culverts are required.
