Multi Plate Corrugated Metal Pipe Elbow Design for Projection in Mountains

When a highway projection start, it will meet lots of terrain, like mountain, basin, highland, river, plain, etc. And we often need a elbow to solute the design problem. When we meet an elbow design, what could we do? As we know, the elbow is a integrate structure in traditional design. But our corrugated steel culvert is in big diameter, if it is an integrate structure, we can not ship it, then we have to consider how to produce the corrugated steel elbow in assembled type.

The structure of corrugated steel elbow for corrugated metal pipe

We have to find a solution that make the corrugated steel elbow in multi plate type. The elbow is with an degree, it is difference to the straight corrugated metal pipe, we have to consider, how to connect the multi plate, and we find that the flange is a good choice to be the solution.

Firstly, our engineer will make a detailed design for the corrugated metal elbow, how many pieces of corrugated steel plate it needs, the shape, size of each corrugated steel plate.

Then We produce same diameter straight corrugated metal pipe, our people will assemble the metal pipe to be a round culvert pipe and we cut the round corrugated metal pipe as per our engineer design to make the angle as same as our request elbow, Then we disassemble all sections of the corrugated metal pipe which had been cut by us, finally welding flange on the edge of the cutting corrugated steel plate.

After all process finishing, our workers will try to assemble the elbow again, then if no problem, my engineer will according to the real produced elbow to amend his drawing, after that, the elbow design is finished.

Why we have to consider corrugated steel elbow on highway construction projection

Some people think the culvert is straight, and culvert is intersection with the highway direction, why we need an elbow for the culvert. In fact, on the big projection of highway, we can meet the problem that the mountain or trench is stopped culvert direction. If we filling the trench or excavate the mountain, it will spend big cost and time but an elbow can be a best solution for this problem. Elbows can allow corrugated pipes to bypass obstacles, and save construction term and cost.

Multi plate corrugated steel elbow is suit to ship

The corrugated steel elbow is as same as the multi corrugated metal pipe, it is assembled by pieces of corrugated steel plate, then it is easy to load in container, but it is still need a little more space than the corrugated metal pipe, the multi plate for the corrugated metal pipe, they are same size, and similar arc, it is easy to pile together. But the multi plate for corrugated metal elbow, they are difference size, difference arc, then need more space to strap and put it. Anyway, it is much easier for shipping now.
