Textured tube fittingCompared to reinforced concrete pipe culverts, it boasts advantages such as thin pipe sections, light weight, ease of transportation and storage, simple construction methods, rapid assembly, and a short construction period.
During the construction of corrugated pipes, they can be assembled into any desired length as needed. In case of necessity, pipe sections can also be disassembled and relocated for construction elsewhere. The superiority of corrugated pipe culverts is particularly pronounced in areas lacking sand and stone materials or where the ground bearing capacity is low.
Bellows culverts have long been widely used in foreign highway, railway, and building construction projects. Some developed countries not only have factories that manufacture bellows sections but also have issued design and construction standards or codes for bellows culverts. Before liberation, China's highway and railway departments also used imported bellows sections from abroad. Currently, China has factories specializing in the production of bellows culverts. Given the many advantages of these culverts, the prospect for their application and promotion in China is very promising.
