Abstract
Concrete pipe including a hollow tube of concrete with a grid of reinforcing bars embedded therein. A plurality of inserts are embedded in the concrete pipe in between the bars of the grid and have passageways therethrough to form slots between the interior of the concrete pipe and the exterior thereof at predetermined locations to form slotted concrete pipe. The inserts are attached to the grid of reinforcing bars during formation of the pipe and the concrete is introduced to surround the grid and inserts and is permitted to set. Thereafter, the formed concrete pipe contains embedded reinforcing bars and inserts in predetermined locations resulting in a slotted reinforced concrete pipe.
