Application of steel corrugated pipe culvert in highway engineering

steel corrugated culvert pipe, also called culvert pipe, is a corrugated pipe for culverts laid under highways and railroads. corrugated metal pipe adopts standardized design, centralized production, short production cycle; on-site installation of civil engineering and profile installation can be implemented separately, short construction period, at the same time to reduce or simply discard the conventional building materials, environmental protection is far-reaching; and has to adapt to the deformation of the foundation, the force situation is reasonable, to reduce the advantages of uneven settlement, to solve the problem of damage to the concrete structure of bridges and pipe culverts in cold areas.

According to the survey, the service life of steel bellows can be more than 100 years due to galvanized treatment and asphalt anti-corrosion treatment. The assembled corrugated pipe section adopts Q235-A hot rolled steel plate, and each circle consists of several steel plates connected to form a whole, and then longitudinally connected and molded. Connecting bolts adopt M 208.8 grade high strength bolts and HRC35 grade curved washers, the surface of steel plate is hot-dip galvanized, the plate joints are sealed with special sealing materials, the foundation of pipe culvert is 50-100cm gravel bedding, with a compactness of N95%, and the hole paving is made of M7.5 slurry masonry piece stone, and the slope of pipe culvert flowing water surface is 5%. General corrugated steel culvert in addition to the above pipe type, there are elliptical, flange type complete installation, etc., the import and export can also be made in accordance with the proportion of side slope beveled.
