The installation and laying of metal corrugated steel plates should be smooth and stable, and there should be no reverse slope at the bottom of the pipe. There should be no soil, bricks, or other debris inside the pipe culvert. Effective measures must be taken to ensure the quality of backfill soil for steel corrugated pipes. After the high-strength bolts are tightened, they should be coated with sealing waterproof material (or hot asphalt) at the overlap before the secondary anti-corrosion treatment.

Used for crossing natural valleys and depressions to discharge floods, or crossing roads as overpasses for people, livestock, and vehicles, or irrigating farmland as canals. Culverts are mainly composed of the tunnel body, foundation, ends, and wing walls. Culverts are constructed using materials such as bricks, stones, concrete, and reinforced concrete based on the principle of connectors. Generally, the aperture is small, and the shapes include tube, box, and arch.

Appearance regulations: The installation of steel corrugated culvert pipes must be straight and smooth, and the pipe mouth should be consistent with the slope of the embankment. The joints of steel corrugated culvert pipes must be tightly bonded, and waterproof sealing materials must be effective. With the accelerating process of highway construction in our country,Improvement of steel processing technology, especially anti-corrosion material technology,Steel corrugated culvert pipes have good mechanical properties and simple construction techniques,Adaptable,The advantages of strong durability are gradually being valued in the construction of highways in China.
