Assembled Corrugated Steel Pipe Application on Old Mining Area

When the highway design company accept a new projection, if it is on the old mining area, the engineers have to consider more factors for the projection, because there are lots of cavities and void left after the mining underground were completion. Then the foundation job is so difficult.

The foundation problems on an old mining area

As we know, all construction job, the foundation is the basic of whole projection, to make a firm foundation is the most important guarantee for the projection. Then if we adopt the traditional material to construct the culvert of highway, we have to strengthening the foundation, because underground goaf can cause varying of ground subsidence, it will cause damages on the concrete structure, Normally we inject filling material in the void and cavities, after filling the void and cavities, we can process the next step. It will take long term and big cost on the foundation. And before injection, we also need a long time to topographic survey.

Corrugated steel pipe is a solution for the low bearing capacity foundation

But if we adopt corrugated steel culvert, it will be more safe than the concrete structure. The corrugated steel culvert is a flexible structure. It has strong resistance to deformation and settlement. Though the foundation is with a lower capacity of bearing, the corrugated steel culvert no need to make a special treatment on the foundation, just make layer of gravels is no problem. Then it can save time for foundation treatment, and no much little budget than the concrete structure.

Finally, we know the corrugated steel pipe does not only have the ability to adapt to the deformation of the foundation, it also solve the problem of culvert damage which is caused by the foundation uneven settlement
