Construction of Culvert.
A culvert is a buried structure, similar to a bridge, consisting of single or multi-span construction with a minimum length of 3m for each span. Two horizontal slabs are cast monolithically with two or more vertical side walls, with a maximum span of 6m. Culverts convey stormwater or non-perennial streams across roadways where the soil is weak. They suit difficult site conditions, require minimum maintenance and have a prolonged service life. The following are the types of culvert.
- 1. Pipe culvert (single or multiple).
- 2. Pipe-Arch culvert (single or multiple).
- 3. Box culvert (single or multiple).
- 4. Arch culvert.
- 5. Bridge culvert.
- 6. Metal box culvert.
