SP10 E Headwall

Althon SP ‘Splayed Wing Wall Headwalls’ are produced with a higher wing wall at the front of the apron.  This makes them ideal for inlets or outlets where situated in locations with high/steep embankments or where the structure is required to provide protection to an accessory such as a Flap Valve, Duck Bill Valve, Stop-Logs or Weir Wall.  Althon SP10 precast concrete headwalls offer a cost effective alternative to in-situ structures for connecting pipework discharging into open watercourses.

All SP10 concrete headwalls are cast to suit the diameter and type of pipe being used and can be provided with fixings cast in at the time of manufacture to accommodate gratings, trash screens, flap valves, ladders, guardrails and flow and depth monitoring equipment.

 

All Althon SP Headwalls are available with either 300 or 500mm thick toe extensions. If you cannot find the drawing or information you are looking for please contact us.
