When you have a drainage pipe designed to discharge water, it is best to install a headwall drainage outlet. Headwalls make sure that the water flow does not erode the pipe or any surrounding area. In addition, they provide support for bridges, roads and other structures while allowing water to pass through without any barriers. So, what places are you most likely to find the use of headwalls? Also, what are the main benefits of installing one?
What is Headwall Drainage?
A headwall is a small retaining wall built at the inlet or outlet of a storm water drainage pipe or culvert pipe. Industries put them in place to reduce any erosion to the pipe and surrounding area caused by the constant flow of water. They are designed to prevent the growth of plants around the pipe that may damage or block the flow. Headwalls are often made from precast concrete to ensure durability and long life, although other materials such as stone and plastic can be used. Headwalls often also include wing walls to direct water flow to the pipe and away from any soil.
Where Can We Find Headwall Drainage?
Headwalls are often found where drainage pipes flow into streams, ponds or other waterways. As retaining walls, they are often built to provide support for roadways and bridges, allowing water to flow under and protect the structure of both the pipe and road overhead. They are built into the side of slopes with concrete wings to protect the surrounding area from soil erosion. You may also find headwalls in areas that are prone to flooding, as they help to control and stabilise the flow of water that is discharged. In such cases, flow control attachments may also be applied to the drainage outlet.
Benefits of Headwall Drainage
- Headwalls are a low cost solution to prevent the erosion of soil and drainage pipes.
- They are built using strong, durable materials so that they last a long time.
- They prevent drainage water from damaging the road structure while also providing structural support.
- Headwalls direct the flow of water, reducing damaging turbulence and ensuring the efficiency of the pipe.
- They act as a marker that indicates a pipe opening, protecting pipes from accidental damage during maintenance.
- They help protect pipes from being crushed by the force of the road overhead.
