This is a sectional structure with rebated joint, assembled on site around the drainage pipe and locked together by means of stainless steel cast-in sockets and brackets provided. The H28C H penstock headwall is suitable for penstocks up to 1000mm. Available with a standard backwall height of, 1.65m. Lifting points cast in to each wingwall for safe handling using Althon lifting clutches are also included.
We cast the opening in the back wall of our headwalls to suit the pipe diameter and material of the pipe being used. We can cast multiple pipe openings, elliptical, square or rectangular culvert openings into any of our headwalls. We can also cast pipe openings into the wing walls of our headwalls.
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.
