Assembly type corrugated metal pipes are assembled by arc corrugated plates. They are widely used in culverts, galleries, bridges, tunnels, temporary detours, drain pipes of highway and railway and mine retaining walls of roadway supporting.

Assembly type corrugated metal pipes are standardized designed and centralized manufactured. Productions are fabricated according to customer’s request or the drawings requirement. These pipes are very adaptable to various environment. Construction and sectional materials can be carried out separately, thus normal materials can be reduced or totally abandoned, which shorten the working period and also gain an environmental significance. The structure of assembly corrugated pipes bears a rational force, and the load of power is distributed. Also the pipes’ non-deformability is very well, it’s a solution to the damage to the culvert from frost. The road surface above the culvert pipes is very plain, and thus improves the comfortableness of car. These pipes avail to improving the structure of the soft soil foundation and the interlocking of the junction of the embankment, which improves the safeness of the car on the bridge. The maintenance cost of corrugated metal pipes is very low, and the cost of engineering practice is also lower than other bridge culverts. Corrugated metal pipe is a very promising product because of its unique advantages and adaptability.
