The wide application of drainage bellows involves highways, railways, construction engineering and other fields. With the domestic output just now in the forefront of the world, the promotion of metal corrugated culverts has become broader. Here is a brief introduction to the relevant performance of the metal corrugated culvert.

 1. The horizontal displacement and deformation degree of the drainage bellows pipe side play a protective role against the turbulence and ups and downs of the road;

  2. The maximum equivalent stress and deformation degree of the drainage bellows when the waveforms of the drainage bellows are different are large, and the profits of the small waveforms are evenly distributed;

  3. The peaks and troughs of the drainage bellows are stress concentrations at the top, bottom, and side of the pipe, and the position of the maximum equivalent stress of each pipe diameter is closely related to the load relationship.

The final results of large-strain analysis and small-strain analysis of drainage bellows are very close. The proposed boundary conditions are well connected with the starting process of the reverse-grooving backfilling method, and the precision is satisfactory.
