- Abstract:
- The concrete pipe with the bell-and-spigot joints is the most common urban drainage pipe structure, but the coupling of the fluid and the overlying load in the pipe may cause damage to the joint and lead to pipe leakage. Based on Abaqus and Fluent finite element software, this paper establishes a three-dimensional refined model of the drainage pipe with gasketed bell-and-spigot joints and the flow field model inside the pipe. With the interaction of pipe and soil, the contact between the bell-and-spigot joint and the rubber as well as the fluid in the pipe being considered, the structure and fluid model are solved jointly by using MpCCI (Mesh-based parallel Code Coupling Interface) platform. The influence of different flow rates, different traffic load amplitude and different load position on the dynamic response of the socket is mainly studied. The results show that under the multi-field load, the maximum principal stress and vertical deformation of the central pipe joint are the largest, and the stress distribution of the pipe bottom and the pipe top is the same, both are tension stresses, but the stress value at the bottom of the pipe is slightly larger The change of flow rate has a little effect on the mechanical response of the bell-and-spigot joint The magnitude of traffic load amplitude has a significant effect on the maximum principal stress and vertical deformation of the bell-and-spigot joint, and the influence is concentrated on the central pipe joint The movement of the load position has obvious influence on the vertical deformation of the bell-and-spigot joint and the mechanical response of the top and bottom of the pipe.
