Corrugated culvert (plate) advantages: 1. Easy to maintain, just ensure proper protection and maintenance of the inner wall.
Two, steel corrugated pipe offers significant economic benefits in areas with frozen soil and soft soil roadbeds.
Three, steel corrugated pipe has been treated for corrosion resistance, offering high durability.
Four, its good integrity and plasticity provide 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 stability of the subgrade.
Steel corrugated pipe products are available in assembled and prefabricated types; 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 crown fill heights from 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. General for 125-25 wave patterns, 3-Smm steel plates are typically used, while 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 satisfy fill up to d2 meters.
Earth height: 0.6-33 meters, meaning the earth fill thickness on the pipe is 0.6 meters, and the fill thickness is 33 meters. If exceeding 33 meters, the load-bearing capacity must be increased by increasing the wall thickness or other methods.
The landfill area allows for the passage of vehicles weighing up to 120 tons. Entrance Design: The gate is designed as a Chinese character wall, and the slope entrance is as shown in the right figure. Slope: Due to the涵管与 (The Chinese character is missing, please provide the complete word or phrase.)
Road intersection angles not 90 degrees and special angle culverts required. Slope entrance/exit culvert design requires special angle culverts.
