SP10F precast headwalls are produced with wing walls 590mm high at the front of the apron. SP10F precast headwalls are for inlets or outlets situated in locations with high or 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. SP10F precast headwalls have been designed to suit plastic and clay pipework up to 500mm or concrete pipework up to 450mm and have a backwall height of 1040mm. Althon SP10F precast 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.
SP10 precast headwall units can be factory fitted with a range of accessories such as flap valves, penstocks, Kee Klamp® handrails and a selection of gratings depending on the application. The SP10F headwall weighs 2230kg.
