What Does End Section Mean?
The end section of a culvert is a flared attachment provided on either side of the culvert pipe for the purpose of improving hydraulic efficiency and preventing erosion.
The end sections can be standard flared end sections, bevel cuts, safety slope end sections and safety apron end sections. Trash and rodent guards can also be provided at the end sections.
Trenchlesspedia Explains End Section
Installing end sections greatly increases the operating efficiency of a culvert. It should be installed simultaneously with culvert installation and is done by tamping soil around the end section. Sedimentation and scouring conditions can be improved and a better control over head water depth can be achieved. Collection of floating debris, water plants and weeds is also reduced. It also gives an aesthetic appeal to the appearance of the road it serves.
