Corrugated Steel Pipe Culvert Design for Highway

Corrugated pipe culvert is assembly corrugate pipe or corrugated plate to a culvert form, analysis from structure and function connection, steel corrugated pipe culvert performance is flexible,Steel corrugated culverts can adapt to foundation deformation,It can also solve the problem of uneven settlement. Due to the axial corrugated steel corrugated pipe culvert has excellent mechanical properties , it can be dispersed to a larger range in both axial and radial directions,Especially when it is a poor engineering practice in areas , like frozen soil, expansive soil, and collapsible loess,There are many advantages of corrugated steel pipe culverts construction,and also has broad applications.

Culvert design requirements

The culvert design needs to consider the resistance to floods, and Mudslides can pass through for safe drift, and the impact of erosion factors should be considered too. nearby bridges should also be considered to ensure stability

Before or during the construction of bridges and buildings, the design of pipe culverts should be considered, the improvement of river diversion should be considered enough .

The culvert design should pay attention to the terrain conditions of the riverbed and not compress the river channel

The aperture should be based on the design of flood, geological bed, riverbed slope, etc, When water accumulation is allowed to cross the bridge, it can be calculated appropriately reduce, the reduced flow should be less than 1/4 of the total flow.

Culverts should be designed as pressure free and designed at the highest water level frequency meets regulations.

Calculate the vehicle load caused by vertical soil pressure.

Applicable conditions for culverts

Scope of adaptation

From the perspective of road service life, if the service life of culverts can Reaching 50 years, it can meet the needs of use, so it is suitable for general highways Corrugated steel culvert.The severe uneven settlement of foundation leads to reinforced concrete culverts. If there is a problem with the pipe, the waveform pipe culvert can solve the damage caused by settlement deformation of the culvert foundation,The flexible structure of corrugated pipe culverts is beneficial，it can improve the adverse conditions of soft soil roadbeds.

Applicable conditions

Application analysis of corrugated steel culverts:

There must be sufficient wall thickness to ensure the maximum stress of the steel corrugated pipe

The anti-corrosion treatment of steel corrugated pipes should be depended on certain requirements , the anti corrosion to ensure Steel corrugated pipe culverts have sufficient corrosion resistance within a certain period of time.

Steel corrugated pipes should be able to withstand deformation, which is caused by standard loads

Selection of Steel Corrugated pipe Culverts

When selecting steel corrugated culverts for highways, it is necessary to comply with the application safety requirements

Full principles to meet functional requirements

The construction of corrugated steel pipe culverts can be considered in the following areas: poor Stone foundation, such as frozen soil, collapsible loess, etc; High risk and hypoxic areas, etc

Application trends of steel corrugated pipeculverts

With the widespread application of steel corrugated pipe culverts, ISO strong corrugated pipes will be Used for assembling large span culverts, tunnels, and corrugated structures. Prefabricated corrugated pipe culvert, able to meet the requirements of different spans and heights

Social benefits of corrugated steel pipe culverts

In the application of steel corrugated pipe culverts, it is beneficial for environmental protection. The construction period has been shortened,too. It has increased economic benefits in cold regions and it has obvious advantages.
