Response of Bell and Spigot Joints in Culverts under Vehicle Load
While a significant number of long-term sewer pipe and culvert failures result from joint leakage and erosion of backfill, there have been very few studies examining the behaviour of pipe joints. There is no established method for the design of bell and spigot or other joint types. Reported here, therefore, are test results on 600-mm diameter reinforced concrete, 900-mm diameter polyvinyl chloride, and 1500-mm diameter high density polyethylene pipes with gasketed bell and spigot joints. Full-scale live load tests on jointed pipe systems were conducted in the test facility at Queen's University, involving two different burial depths and three different surface load locations relative to the joints being evaluated. The experimental results are presented and assessed to determine the key demands generated at the joints and how they are influenced by the loading location, burial depth and pipe material. The different characteristics of soil-structure interaction for joints in rigid and flexible pipes are highlighted. Finally, joint performance in the laboratory is discussed in the context of the development of structural design methods for joints.
