Corrugated culvert equipment is also called metal corrugated culvert or corrugated culvert, which refers to the threaded corrugated pipe buried in the highway and the culvert under the railway. Pipes are widely used for culverts (pipes) in highways, railways, small bridges, passages, retaining walls and various mines, roadway retaining wall support and other projects.
① High strength, due to its unique corrugated structure makes it more than 15 times the compressive strength of cement pipes of the same caliber.
② Convenient transportation, the weight of the corrugated pipe culvert is only 1/10 to 1/5 of the same diameter cement pipe. Even if there is no transportation equipment in a narrow place, it can be transported manually.
③ Long service life, the steel corrugated pipe culvert is made of hot-dip galvanized steel pipe, so the service life is long, and the service life is 80-100 years. When it is used in a particularly corrosive environment, the steel with the inner and outer surface bitumen coating is used The bellows can be increased by more than 20 years on the basis of the original service life.
④ Convenient construction: corrugated pipe culvert is connected by sleeve or flange, and the length can be customized according to needs, even unskilled workers can operate, construction can be completed in a short time with a small amount of manual operation, which is fast and convenient .
⑤ Excellent economy: The connection method is simple and can shorten the construction period.
