Corrugated pipe (sheet) advantages: 1. Easy maintenance, simply ensure the inner wall is well-protected and maintained.
Two, 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 and boasts high durability.
Four, its excellent integrity and plasticity offer strong resistance to deformation on complex geological 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 two structural types: assembled and prefabricated; cross-sectional shapes include circular, elliptical, horseshoe, arch, etc. The pipe diameter range is 0.3m.
—12m length, with processing thickness ranging from 1.6mm to 7mm, capable of meeting the requirements for structures with a pipe top backfill height from 0.5m to 60m. Wall thickness: refers to the thickness of the steel plate forming the pipe wall.
The standard for 125-25 wave patterns typically uses 3-Smm steel plates, while for 200-55 wave patterns, 3-8mm steel plates can be used. Diameter: refers to the inner diameter of the corrugated pipe.
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 support a fill height of d2 meters.
Earth height 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 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 eight-character wall, as shown in the right figure. Slope Entrance: Due to the culvert and...
Road intersection angles not 90 degrees, requiring special angle culverts. Culvert entrance and exit slopes: Due to the use of sloped culvert openings, special angle culverts are required.
