Diverse-shaped metal bellows

Corrugated pipe (sheet) advantages: 1. Easy to maintain, only requires proper protection and maintenance of the inner wall.

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

Three, the steel corrugated pipe has undergone anti-corrosion treatment, featuring high durability.

Four, its good integrity and plasticity provide strong resistance to deformation in complex geological conditions of road sections.

V. Its good thermal conductivity results in minimal disturbance to the subgrade in frozen soil areas, ensuring stability of the subgrade.

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

—12m in length, with a processing thickness of 1.6mm to 7mm, capable of meeting the requirements for structures with a pipe crown fill height of 0.5m to 60m. Wall thickness: refers to the thickness of the steel plate forming the pipe wall.

The general specification for 125-25 wave patterns uses 3-Smm steel plates, while for 200-55 wave patterns, 3-8mm steel plates can be utilized. Diameter: refers to the inner diameter of the corrugated pipe.

Backfill Height: The height of backfill that a certain model of corrugated culvert can accommodate, for instance, a 200-55 corrugated culvert with a wall thickness of 4.5mm can satisfy a backfill height of d2 meters.

Soil height is 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 increasing wall thickness or other methods.

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...

Non-90-degree road intersections requiring special angle culverts. Culvert inlets and outlets feature sloped openings, necessitating the special angle culverts.
