A fully-sealed tunnel built by ground/soil creating a path for vehicles, pedestrians, or animals through small bodies of flowing water and external obstructions is called a culvert.
Two separate types of culverts are the slab culvert and the panel culvert. An engineer must know the differences between these two culvers in order to choose between them. Below are the main differences between the culvert of the slab and the culvert of the box. Read More
| Sl.No | Box Culvert | Slab Culvert |
|---|---|---|
| 1 | Box culverts are rectangular four-sided structures, the lower side pressed down into the ground, the top serving as the roadway and the lateral sides supported by the soil on either side of the obstruction. | Slab clamp, also known as bridge clamps, can be three-sided or simply a deck slab embedded on both sides of the soil, providing a bridge over the distance. |
| 2 | The containers are usually 3'x2 ' or 12'x12 ' in 1 ' period and raise increments. (Usually in 6 ' to 8 ' lengths) | The normal size of the duration is between 8 ' and 48 '. |
| 3 | Standard design: ASTM C 1433 | Standard design: ASTM C 1504 |
| 4 | Thanks to the bottom slab, the rate of flowing water can shift | Slab culverts do not have bottom slabs, thus maintaining natural water flow and maintaining intact the natural bottom substratum. |
| 5 | The box-shaped slabs ' blunt corners find it unsuitable for high-speed vehicles. | Slab culverts do not have any sharp corners that threaten the safety of high-speed vehicles. |
| 6 | Box culvert is needed for artificial flooring purposes. | Slab corners may substitute box corners if there is no need for synthetic flooring |
| 7 | It can be used for storage or irrigation of rainwater, but it may not have been used in dry seasons. | This offers a path through small streams and external obstructions. |
