Abstract
A fluid jacket concrete pipe system includes a concrete pipe enveloped by a fluid-filled jacket. The fluid-filled jacket includes an inner jacket wall, an outer jacket wall, and a first and second side wall interconnecting the inner jacket wall to the outer jacket wall. A fluid inlet is disposed on the outer jacket wall. The outer jacket wall has a thickness dependent on a diameter of the concrete pipe and an external loading of the fluid jacket concrete pipe system.
