The use of corrugated metal pipe from its stress characteristics, corrosion analysis, application of corrugated culvert must meet the following conditions.
1, the corresponding waveform must have enough to ensure that the wall thickness of corrugated steel culvert structure in the load when the maximum stress is lower than the allowable stress of the steel structure.
2, anti-corrosion treatment of spiral corrugated metal pipe, to ensure that a certain number of corrugated culvert has sufficient corrosion resistance.
3, the deformation of corrugated culvert can withstand the load caused by the standard, does not produce nonlinear destruction, and does not affect the structure layer function.
