Wing, L & U Type Headwall
The Wing, L and U Type Headwalls are used at the end of the pipe. These structures are typically on the side of a road, in a desilting basin, or anywhere a pipe starts or ends that is not in conjustion with another structure type. They are used to prevent erosion around pipe openings. You will typically see this type of headwall in areas where the slope is contoured around the wall, like the corner of a desilting basin.
