b'STORMWATERCATALOGHEADWALLSUnderground storm sewer piping will sometimes penetrate aboveground in the form of a drainage ditch, pond inlet, or discharge. There is a potential for soil erosion to occur around the pipe due to the unbridled nature of stormwater. To help prevent this erosion, a headwall is used to terminate the pipe. The headwall is a precast concrete structure with wings and a bottom to deflect the water away from the soil.Headwalls are used to provide support for bridges and roadways by anchoring the piping to prevent movement beneath bridges and roadways caused by hydraulic and soil pressures. The headwall helps prevent soil erosion andModel DSA-01scouring from turbulent stormwater and prevents adjacent soil from sloughing into the waterway.Optional features for headwalls include trash screens, security screens, energy dissipators, flap valves, gate valves, stop logs, and handrails.ParkUSA offers headwalls to meet the needs of varied project requirements. Components of an effective stormwater drainage network can include: catch basins, junction boxes, curb inlets, manholes, drainage pipes, headwalls, safety end treatments, detention basins, stormwater quality interceptors, and pump lift stations.DRAINAGE FEATURES Single-piece construction Easy installation of base sectionBENEFITS Model DSB-01 Offers rugged durability for storm [LJ2] water conveyance and erosion prevention Quick and easy installation Available in flared-end or three-sided construction to provide an opening for stormwater runoff Cylindrical flared-end sections are seamless pipe ends that taper open to the base Three-sided design fits the pipe end to a wall with wings and a flat base Terminates drainage pipe Variety of sizes availableModel SGHINFO@PARKUSA.COM|888-611-7275|WWW.PARKUSA.COM 127'
