Assembling of Corrugated Steel Culvert

The corrugated steel pipe is popuar because it is economic for transporting. It is manufactured in pieces of structure plates, when the corrugated steel pipe culvert is on job site, we can assemble the structure plates to be a culvert pipe.

Method of assemble the corrugated steel pipe culvert

It will be not difficult for assembling just in right method. We will assemble the first ring firstly. For example, if the culvert is assembled by 5 strcuture plate in each ring, then we connect 2 strucutre plates firstly, and then the 3rd, the 4th and the 5th plate one by one. After finish the whole ring, we tight the bolts, and irrect the first ring on the bedding of construction site.

Then we start to assemble the second ring. The first step is connect 1 strucutre plate on the first ring, and do not tight the bolts. Then the 2nd plate until the 5th structure plate are connect to the first ring one by one, do not tight the bolts before finish the whole ring, it will be easy for us to assemble, if tight the bolts early, the structure plate can not be moved, it will be difficult to match the holes for bolts. After whole of 2nd ring are connected, we tight all bolts. Then one ring by one ring we assemble, until finish the whole culvert.

Connection method on circulating direction

It is simple to connection on the circularing direction. Just one end of a strcuture plate overlap another structure plate is OK, and keep same direction, for example, the whole ring is assembled by 5 plates, the 1st plate is overlap on the 2nd plate, the 2nd plate is overlap on the 3rd plate, the 3rd plate is overlap on the 4th plate, the 4th plate is overlap on the 5th plate, finally, the 5th plate is overlap on the 1st plate.

Connection method on axial direction

We have two design for axial direction connection.

Firstly, it is big ring overlap on small ring. Like that, the first ring is big ring, and the second ring is small ring, then the first ring is outside to overlap on the 2nd ring, and the 3rd ring is big ring too, then the 2nd ring is in the 3rd ring, then same as before until finish the installation of the culvert.

Secondly, it is big side overlap on the small side. Each strcuture plate has a bigger side and a smaller side. Then when we assembling rings, it means each ring has a big side and a small side, just big side is out the small side is OK, after assembling, it looks like a fish scale.

Assemble of difference shape of culvert

Normally, the culvert pipe is in round shape. Then when we produce it, we will design the structure plate are all in same specifications, then it will be easy for assembling. Just assemble the structure plat one by one is OK.

If it is a pipe arch or arch, it has more than 2 radius, we have to assemble it as per the drawing. We will make mark on each structure plate, and assemble as per the assembling drawing is simple.
