Culvert is a channel that brings a stream under a bridge or railway. A Culvert will serve as a pedestrian bridge to move through it. It is typically found in a natural water movement that serves the purpose of a bridge or current flow device.
Culverts are available in many shapes such as round, elliptical, flat, pear-shaped, and box-like structures. Culverts are capable of loading and water flow, lifespan and bedding and backfill installation. The sort is based on a number of variables including tidal, upstream, highway and other circumstances.
Following are the Different Types of Culvert:
- Box culvert (single or multiple)
- Arch culvert
- Pipe culvert (single or multiple)
- Bridge culvert
- Pipe-Arch culvert (single or multiple)
- Metal box culvert
Pipe Culvert
Because of the competitive price and simple construction, Pipe culverts are the most common types of culverts. These are found in various types such as the round, elliptical and arch of the shaft. Our forms are usually based on circumstances and restrictions on the ground. Small-scale pipe corners represent normal pipes such as concrete pipes.
Advantages of Pipe Culvert
It can be designed by proper mixing method, size, and reinforcing of any required intensity.
They are inexpensive.
These pipes can withhold any tension of tensile and compressive stress.
River passage is under the foundation.
Disadvantages of Pipe Culvert
The main drawback of the Pipe Culvert is that it can be quickly corroded at the crown owing to the organic matter of the bacteria and the leakage of poisonous air, known as Crown corrosion.
Pipe-Arch Culvert (Single or Multiple)
Arch culverts are ideal for a large opening in rivers where a greater hydraulic benefit can be given to fish. They also provide low security, and they are definitely a lot of fun. At sites where the headroom is small, pipe arches are particularly useful and also have a hydraulic benefit at low flows.
Advantages of Pipe-Arch
- Hydraulic capacity improvement at low flow
- Limited headroom condition
- Lightweight
- Easy to install
- Aesthetic look and form
Box Culvert
Box culverts are made of concrete and RCC (Reinforced Concrete) in particular. The most challenging part of a box culvert is that it needs a dry surface to be mounted. However, due to the nature of the concrete floor, when a significant volume of water is expected, the course of water may be changed. This function renders box culverts, one of the culvert’s most frequently seen types.
