How to Assemble Flanged Nestable Corrugated Metal Culvert

How to assemble flanged corrugated metal culvert

Normally there are two design of the flanged nestable corrugated metal culvert assemble.

For circumferential direction assembling

Just put the flange together and connected by bolt sand nuts, it is very simple. but before assembling, we have to classify the upper plate and lower plate, then it will save assemble time.

We suggest the plates adopt stagger assemble, in theory, stagger assemble is stronger than be assembled ring by ring.

For axial direction assembling, there are two method.

One design is the structure plate is with one big end and one small end, when assemble it, the big end overlap outside of the small end, then one by one, one ring by one ring until the total length is complete assembled.

The other design is big ring and small ring, when assemble, the big ring plate is overlap outside of the small ring, like big ring with small ring with big ring, one by one, until the whole culvert is completed.

If the projection is a water drainage project, we suggest the first assemble way in axial direction. Because the big end overlap on the small end, it looks like a fish scale, it will has little leakage of water.
