Corrugated Steel Culvert Are Used in Highway Construction

corrugated steel culvert

Corrugated pipe culvert is also called steel/metal corrugated pipe culvert, which is laid and buried under highway and railway culvert.

Corrugated pipe culvert is widely used in culvert of highway, railway, Small bridges, passages, retaining walls,and various mine projects .

Replacing reinforced concrete with metal corrugated pipe culverts

for culvert construction, not only suitable to permafrost regions,but the Northern Plateau Region, because the corrugated pipe culvert can solve the problem of culvert concrete structure damage in north cold area. At the meanwhile, corrugated pipe culvert technology is also suitable to low foundation bearing capacity areas such as soft soil, expansive soil, and collapsible loess Soft soil, expansive soil, collapsible loess areas, and frequent earthquake areas.

According to analysis, the advantage of using steel corrugated pipe culvert on project is very obvious, such as the high structural strength of corrugated pipe culvert, it is 2-3 times of reinforced concrete; the corrugated pipe culvert service life is long, it can reach more than 100 years, it has lighter weight than reinforced concrete ,which is only 10%-20% of reinforced concrete ; besides, The construction is very convenient, and the construction period is feasible Shorten by half.

Why do metal corrugated pipe culverts with flexible structures have such high strength?

Why do metal corrugated pipe culverts have such high strength? someone may ask. That is because the flexible structure of corrugated pipe culvert can convenient Bending, stretching, and compression, it is also because of the corrugated structure, which makes the culvert pavement be subjected to reasonable forces, with uniform load distribution, and make the pavement to have a certain degree of deformation resistance

In theory, when the metal corrugated pipe culvert in the culvert is in working condition,especially when the loading from pavement is big, the corrugated pipe culvert will be out of shape because of the compression,And as a result, squeeze the soil or other fillers on both sides of the sidewalls, at this point, the soil on the sidewall will generate a reaction force to against the corrugated pipe from the deformation.

At this situation, it improves the corrugated pipe culvert ability to adapt the foundation deformation, and this effectively solves the problem of culvert damage caused by uneven settlement of the foundation.

The construction of metal corrugated pipe culverts causes minimal environmental damage, so it also suitable to areas with fragile ecological environments .

At the meanwhile, the corrugated pipe culvert are standard designed and produced, so it can be suitable to used on projects with high quality requirements and tight schedule, which make corrugated pipe culvert is widely used and receive good reputation
