Corrugated pipe culverts is made of 2.0-7.0mm thin steel plate which is made in to corrugation shapes, and the corrugation shape steel plate is made into pipe joints or corrugation plates, and then assembly to the whole pipes, this structure can strength the stiffness and the loading.
The main material of corrugated pipe is SS400/Q235, and it needed to be hot dip galvanizing treatment, the average thickness should be thicker than 84 micron.
Corrugated pipe culvert is one type of soft structure, and has capacity of anti-seismic, and can adapt to larger settlements and deformations, After the construction of the corrugated pipe, it forms a composite structure with the surrounding soil, which jointly bears the force.
There are different cross shapes, such as Circular, elliptical, semi-circular, arched corrugated pipe. The inlet and outlet are divided into straight pipe type and inclined mouth type
The pipe diameter range of corrugated pipe culverts is from D 0.5m to D 16 m. the thickness of pipe wall is 2mm-7mm, and the filling height that can be met is 0.3-60m
The usage range of corrugated pipe culverts
Culverts for vehicles and pedestrian walkways of railway and highway,
Urban comprehensive pipe trench and sewage pipe,
River crossing bridge,
Tunnel lining, open cut tunnel, and maintenance of anti-skid stones at the tunnel entrance,
Windproof passages in cold regions,
Anti slip stone protective tunnel on mountain road,
Coal transportation channels and alleys in open-pit coal mines,
Military: tank hangars, aircraft hangars, air raid shelters, ammunition depots
Highway bridge and culvert construction: Steel corrugated pipe culverts have been successfully applied in multiple highway projects both domestically and internationally, such as the Nanyue Expressway in Hunan Province and the Guizhou Expressway. It has been widely used due to its advantages of stable performance, convenient installation, and economic and environmental protection.
Railway construction: Steel corrugated pipe culverts are also widely used in railway construction, such as the Qinghai Tibet Railway and other projects.
Other engineering applications: In addition to highway and railway construction, metal corrugated pipe culverts are also used for small bridges, passages, retaining walls, and various mining and tunnel retaining wall support projects.
International promotion: After 40 years of market promotion, metal corrugated pipe culverts have been widely used in highway and railway construction in regions such as China, Africa, and Europe, and have been unanimously recognized by local owners, supervision units, and construction units.
Steel corrugated pipe culverts have a wide range of application prospects in modern engineering construction due to their advantages such as high strength, flexible elasticity, deformation resistance, convenient construction, economic and environmental protection, durability, and convenient transportation. Its successful application in highways, railways, and other engineering projects further proves its enormous potential and value as a new type of bridge and culvert.
