A one-piece reinforced concrete Headwall to suit Twin Wall Pipes up to 500mm ID and Pcc Pipes up to 450mm ID. The hole in the back wall is cast rectangular to allow the pipe to enter at an angle of up to 45 Degree and therefore discharge at 45 degrees to the flow. This unit is available in both left and right hand versions. Four 10T – 340 Capstan Lifters are cast into the top of the back wall and the apron for lifting and positioning. The toe is cast separately and is available in depths of 300, 600 and 900mm as standard with other sizes made to order. The toe is fixed to the underside of the Headwall with 20mm Dia Stainless Steel Dowels at 600mm centres secured with High Strength non-shrink grout into 75mm Dia Dowel Hole.
Althon Headwalls offer a cost effective alternative to in-situ structures for connecting pipework discharging into open water courses.
All drainage pipes discharging into open watercourses, such as swales, ditches, ponds and rivers, should be fitted with an appropriate Althon headwall.
