Corrugated steel culvert (HSDG) is a highway construction material that serves as an alternative to circular culverts, box culverts, arch culverts, small bridges, and cover slabs, and can be used for highway-rail grade crossings and embankments.
In projects involving roads, culverts, drainage pipes, and shelters, etc. Advantages of corrugated culvert (sheet): 1. Easy to maintain, just ensure the protective maintenance of the inner wall.
Section II: 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 enable strong resistance to deformation in complex geological conditions.
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 two structural types: assembled and prefabricated. Cross-sectional shapes include circular, elliptical, horseshoe, and arch, etc. The pipe diameter range is 0.3m.
—12m in length, with a processing thickness ranging from 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.
Dimensions: Typically, for 125-25 wave patterns, 3-Smm steel plates are used, while for 200-55 wave patterns, 3-8mm steel plates can be employed. Diameter: This refers to the internal diameter of the bellows.
Filling Height: The maximum depth of backfill that a specific model of corrugated pipe can accommodate, for instance, a 200-55 corrugated pipe with a wall thickness of 4.5mm can handle a filling height of d2 meters.
Soil filling 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, increase the wall thickness or other methods to enhance the load-bearing capacity.
Load capacity. Up to k cubic meters of fill soil can accommodate vehicles weighing up to 120 tons. Tunnel entrance design: As shown in the right figure, the slope entrance features: Due to the culvert...
Special angle culverts not at a 90-degree intersection with the road. Slope from: Due to the oblique mouth design of the culvert's inlets and outlets, a special angle is required.
