Headwall or Endwall– An integrated wall that is situated at either end of a drainage pipe or a structure that crosses a stream or other body of water. A headwall is a wall that is constructed at the intake of a pipe.
What is a concrete headwall, and how does it work?

• Share this story on your preferred social media network! In drainage and culvert construction, a concrete headwall is a structure built at the outflow of a drain or culvert that serves as a retaining wall to prevent erosion and as a way of diverting flow. A critical component of drainage culverts and bridge sections, precast concrete headwalls and wingwalls are used to support the structure.

What is a headwall structure?

In drainage and culvert construction, a concrete headwall is a structure built at the outflow of a drain or culvert that serves as a retaining wall to prevent erosion and as a way of diverting flow. Drainage culvert headwalls and wingwalls made of precast concrete are essential components of drainage culverts and bridge sections.

What is a headwall civil engineering?

An outfall headwall, which can be constructed of a number of materials, is commonly constructed at the outfall of a drain or a pipe culvert to function as a retaining wall and protect fill from scour or undermining, to promote hydraulic efficiency, or to change the direction of water flow.

What is a headwall culvert?

In order to decrease erosion, restrict seepage, retain fill, enhance the visual and hydraulic qualities of a culvert, and make its ends structurally robust, culvert headwalls are added to the ends of the culvert. There are two fundamental types of headwalls available. Safety headwalls and non-safety headwalls are the two primary categories into which they fall.

What is headwall and Wingwall?

All walls, including wings, at the ends of single-barrel pipe culvert structures and multiple-barrel pipe culvert structures are referred to as “headwalls.” • The term “wingwalls” refers to all of the walls at the extremities of box culvert constructions, whether they are single-barrel or multiple-barrel.

What is a concrete headwall?

This building is made of precast concrete and has wings and a bottom that are designed to divert water away from the earth underneath it. Using headwalls, you may provide support for bridges and highways by anchoring the pipes and preventing movement caused by hydraulic and soil forces. You can also minimize soil erosion and scouring caused by turbulent runoff by using headwalls.

Why are headwalls used?

A headwall is a tiny retaining wall that is placed at the entrance or outlet of a storm water drainage pipe or culvert pipe to keep the water from flowing back into it. They were installed by industries to prevent any erosion to the pipe and surrounding region caused by the continual flow of water through the pipe.

What is a headwall in a hospital?

A hospital headwall system is an architectural element in a patient room that serves a functional purpose. Electrical and medicinal gas functions are combined, and the cables and tubing are efficiently managed by the device. Headwall systems in hospitals are intended to enhance the organization and arrangement of medical equipment.

What is a glacial headwall?

The headwall of a glacier is the rocky wall that forms at the glacier’s uppermost terminus (head).

What is headwall erosion?

Stream, valley, or gully lengthening due to headward erosion occurs when a stream, valley, or gully’s drainage basin is enlarged due to a fluvial process of erosion. The stream erodes away at the rock and soil at its headwaters in the opposite direction from the direction in which the stream is now flowing.

What are the different types of culverts?

The Seven Different Types of Culverts

• The following types of corrugated steel pipe (CSP) are available: structural plate corrugated steel pipe (CSP)
• open bottom corrugated steel pipe (CSP)
• concrete pipe
• concrete boxes – precast
• concrete boxes – cast in place
• polymer (plastic) pipe.

What is apron culvert?

Culverts. Apron: a smooth (usually concrete) surface that is put between a culvert and a channel to increase capacity while also reducing erosion and sedimentation. Backwatering is the practice of constructing a culvert or installing a weir in such a manner that there is always some depth of water within the culvert.

What is a headwall in roofing?

A headwall is the point at which the top of a sloping roof meets the side of a wall. The flashing should always extend beyond the edge of the roof covering material. The headwall flashing flange that continues down over the shingles on an asphalt shingle roof, on the other hand, is sometimes concealed by an array of shingle tabs for aesthetic reasons.

What are culverts used for?

The purpose of culverts is to carry water beneath a trail and away from the trailhead. In contrast to an open top box culvert, water from the trail does not drain directly into the culvert in this configuration. For trail applications, smooth plastic or corrugated metal culverts are most typically used, and they are available in both round and square cross-sectional designs.
