Characteristic of Corrugated Pipe Culvert
Advantages of corrugated pipe culvert
① Culverts, bellows culverts, steel bellows culverts, and metal bellows culverts have strong ability to adapt to foundation deformation, and have lower requirements for foundation bearing capacity and flatness, and the actual construction cost is similar or lower than that of bridges and culverts with similar spans .② Short construction period is the most obvious advantage. Civil engineering and pipe joint installation can be implemented separately.
③ Carry out centralized production in factories, and production is not affected by the environment, which is beneficial to reduce costs and control quality.
④ The on-site installation of culverts, bellows culverts, steel bellows culverts, and metal bellows culverts is convenient and does not require large-scale equipment.
⑤ Solve the problem of damage to bridges and pipe culvert concrete structures in northern cold regions (frost).
⑥ The use of conventional building materials, such as cement, yellow sand, stones, and wood, is reduced or completely abandoned, which is of far-reaching environmental significance.
⑦ Culverts, bellows culverts, steel bellows culverts, and metal bellows culverts have reasonable stress conditions, uniform load distribution, and certain resistance to deformation.
⑧ Culverts, bellows culverts, steel bellows culverts, and metal bellows culverts adopt standardized design, with simple production and design and short production cycle.
⑨ Corrugated culverts are beneficial to improve the "staggered" phenomenon at the junction of soft soil foundation structures and embankments, improve driving comfort and safety, and reduce post-work operation and maintenance costs.
Characteristics of steel corrugated pipe culvert
① High strength, due to its unique corrugated structure, it has more than 15 times the compressive strength of cement pipes of the same caliber.② The transportation is convenient. The weight of the corrugated pipe culvert is only 1/10 to 1/5 of the cement pipe of the same caliber. Even if there is no transportation equipment in a narrow place, it can be transported manually.
③ Long service life. The steel bellows culvert is made of steel pipe hot-dip galvanized, so the service life is 80-100 years. When used in a particularly corrosive environment, the inner and outer surfaces of the steel with a layer of asphalt are used. Bellows can be increased by more than 20 years on the basis of the original service life.
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 also operate. 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.
