Ductile steel corrugated pipe

Wavy culvert (plate) advantages: 1. Easy to maintain, simply ensure the protection and maintenance of the inner wall.

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

Section 3: The steel corrugated pipe has been treated for corrosion resistance, offering high durability.

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

V. Its excellent 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 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.

Diameter: refers to the inner diameter of the corrugated pipe. Generally, for 125-25 wave patterns, 3-Smm steel plates are used; for 200-55 wave patterns, 3-8mm steel plates can be utilized.

Backfill Height: The fill height that a specific model of corrugated culvert can accommodate, for example, a 200-55 corrugated culvert with a wall thickness of 4.5mm can meet the fill height of d2 meters.

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

Power. Vehicles weighing up to 120 tons can pass through the allowed backfill area in increments of k cubic meters. Tunnel Entrance Design: The tunnel entrance is designed as an eight-character wall, as shown in the right figure. Slope Entrance: Due to the culvert and...

Non-90-degree road intersection required for special angle culvert. Culvert slope: Special angle culvert needed due to the use of sloped inlets and outlets.
