Ring stiffness is an important factor in the construction and design of buried cable conduit, which determines whether the pipe can resist external forces for a long time. This paper focuses on the experimental study of the ring stiffness of cable conduit. The ring stiffness tests of chlorinated polyvinyl chloride (CPVC) and modified polypropylene (MPP) under different conditions are carried out to verify the influence of thickness and temperature on the ring stiffness of pipe. The test results show that both thickness and temperature have a significant effect on the ring stiffness of pipe. At the same time, the influence of temperature on the ring stiffness of different materials is different, and the possible reasons are analyzed. The conclusion of the experiment has guiding significance for the quality inspection and practical application of cable conduit.
