发明名称 Reinforcing system for concrete pipe
摘要 A truss assembly for reinforcing concrete pipe that includes a mat into which has been woven a series of longitudinally spaced truss bridges that extend across the width of the mat. The mat is cast into a pipe at the points of maximum stress so that the bridges provide circumferentially positioned load carrying sections that are capable of resisting relatively high internal shear and tensile stresses.
