The self-anchored joint uses a special mechanical design to anchor the spigot and socket together, preventing the joint from slipping, while maintaining the flexibility of a slip-in joint to allow a certain degree of angular deflection.
The self-anchored joint uses a special mechanical design to anchor the spigot and socket together, preventing the joint from slipping, while maintaining the flexibility of a slip-in joint to allow a certain degree of angular deflection. By utilizing the self-anchored joint's ability to transfer axial forces, the frictional force and passive earth pressure generated between the pipe segment and the surrounding soil effectively counteract the axial and radial hydraulic thrust. This allows it to replace the function of support piers, achieving a no-support pier design. The self-anchored joints designed and manufactured by Xinxing Cast Pipe are characterized by flexibility, deflection capability, simple structure, high pressure resistance, and reliable pull-out resistance. Therefore, they can be applied in the following situations:
When space, time, or economic conditions are not suitable for setting support piers;
When the pipeline slope exceeds 20% above ground or 25% underground during installation;
When there is a certain degree of foundation settlement.
