What is a steel corrugated pipe culvert?
Corrugated pipe culvert is also called metal corrugated pipe culvert or steel corrugated culvert pipe. It refers to the threaded corrugated pipe buried under the road and railway. It is a circular corrugated pipe made of corrugated metal sheet or semi-circular corrugated steel sheet. It is widely used in roads, railways, small bridges, passages, retaining walls and various mines, tunnel retaining wall support and other projects. The characteristics of metal corrugated pipe culvert are high strength, long service life, convenient transportation, convenient construction and more economical.
1> High strength. Due to its corrugated structure, its compressive strength is more than 15 times greater than that of cement pipes of the same caliber.
2> Long service life. The steel corrugated pipe culvert is made of hot-dip galvanized steel pipe, so it has a long service life of 80-100 years. When used in a particularly corrosive environment, the steel corrugated pipe with asphalt coating on the inner and outer surfaces can be used to increase the original service life by about 20 years.
3> Convenient transportation: the weight of the corrugated steel pipe culvert is only 1/10 to 1/5 of the same diameter cement pipe. Even in narrow places without transportation equipment, it can be transported manually.
4> Convenient construction: The corrugated pipe culvert is connected by sleeve or flange, and the length can be customized according to needs. Even unskilled workers can operate it. The 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.
At present, the culverts of highway projects use metal corrugated culverts instead of reinforced concrete for culvert construction. It is a new technology in China. Metal corrugated culverts have quickly replaced reinforced concrete culverts in highway construction with its stable performance, convenient installation, environmental protection, and low cost. The development prospects are very broad. Compared with reinforced concrete culverts, metal corrugated pipe culverts have the advantages of thin pipe sections, light weight, easy transportation and storage, simple construction process, fast assembly, and short construction period.
Steel corrugated culverts are high-quality highway building materials that replace circular culverts, cover culverts, and small bridges.
Practice has proved that using steel corrugated culverts instead of reinforced concrete for culvert construction has incomparable advantages in terms of construction period, construction cost, environmental protection significance, etc., and using metal corrugated culverts for culvert construction can greatly improve the comfort and safety of road driving, avoid the "skipping and jumping" of culverts in the road, and help solve the problem of frost damage to concrete culvert structures in the northwest and cold regions of my country.
