sprinkler protection from vehicle damage

[djfenn]

Does anyone know of a product sold, like a cement donut of sorts, to install around a sprinkler to prevent damage from cars and trucks along roadsides and driveways

4" Schedule 40 pvc pipe and keeping the sprinkler head 1 -2" below the rim of the pipe... Maybe paint the pipe for cosmetic?

For driveway corners I always recommend converting a few feet to shrubs with a nice big rock to block.
