Our Safe-Slope Headwalls provide a constant sloped front to permit the contact face to be blended into embankments.
Our Safe-Slope Headwalls provide a constant sloped front to permit the contact face to be blended into embankments. This helps to protect vehicles and slashers from damage caused by falling into the space produced by the vertical face of standard Winged and Apron front Headwalls.
The table shows detailed dimensions for the range of Safe-Slope Head Walls. Each type has the same sized opening in the sloped front face, tapering back to the rear. The tapered socket in the rear is different for each pipe, which allows varying diameters of pipes to be inserted from the rear and set with the invert of the pipe level.
When packed and sealed with mortar or suitable compounds, this allows free draining in either direction. Pipes with thinner walls than the design standard may be supported with mass concrete. The connection into the socket should be sealed to prevent erosion of the backfill by stormwater.
