Highway metal corrugated pipe

Wavy culvert (plate) advantages: 1. Easy to maintain, just ensure the inner wall is well-protected and maintained.

Section 2: Steel corrugated pipe offers significant economic benefits in frozen soil regions and soft soil roadbed areas.

Three, the steel corrugated pipe has been treated for corrosion resistance, offering high durability.

Four, its excellent integrity and plasticity offer strong resistance to deformation in complex geological road sections.

Five, its excellent thermal conductivity results in minimal disturbance to the subgrade in frozen soil areas, ensuring stable subgrade conditions.

Steel corrugated pipe products are available in two structural types: assembled and prefabricated; cross-sectional shapes include circular, elliptical, horseshoe, arch, 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.

Diameter: refers to the inner diameter of the corrugated tube. Generally, for 125-25 wave patterns, 3-Smm steel plate is used, while for 200-55 wave patterns, 3-8mm steel plate can be adopted.

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 meet the fill height of d2 meters.

Soil height: 0.6-33 meters, meaning the soil thickness on the pipe is 0.6 meters, and the total 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. Within the permitted backfill area, vehicles up to 120 tons can pass through. Portal Design: The portal is designed as a Chinese character wall, with the slope portal as shown in the right figure. Slope: Due to the涵管与(No Chinese content provided)

Road intersection angles not 90 degrees, requiring special angle culverts. Culvert slope: Due to the oblique entrance and exit of the culvert, special angle culverts are required.
