NOTES
1. Sockets shall be 3" extra strong steel pipe (3 1/2" O.D.). Sockets must be the
proper angle and height so that safety bars are parallel with headwall and side
slope, and are easily removable.
2. Safety Bars shall be 4" extra strong steel pipe (4 1/2" O.D.), or 1/2" O.D. (.250"
wall thickness) steel tubing. Length (20' maximum) shall be the minimum re-
quired to achieve Resin Bonded Anchor placement in full depth concrete. When
multiple bars are required (see table) place bars at equal spacing (30" max.).
3. Bevel culvert pipe to match side slope
4. Resin bonded anchors shall be 7" in length (5" embedment).
5. Centerline of headwall shall be normal to roadway centerline.
