Description
Technical Field
The invention belongs to the field of anti-seismic pipelines, and particularly relates to a pipeline with an anti-seismic structure.
Background
Polyvinyl chloride ("PVC") pipe is often used in buried applications to carry water and wastewater and is typically buried between 2 and 4 feet below ground, but such pipe may also be buried between 15 and 20 feet below ground. In buried applications, surface motion is typically small, especially in areas where seismic activity is minimal. However, surface motion can be large in areas experiencing frequent and intense seismic activity as well as areas experiencing severe expansion and contraction (e.g., coastal areas and areas where the surface is primarily clay or soil described as expansive).
In order to cope with earthquake interference, protective measures generally adopt reinforced pipelines, anti-seismic supports and the like, the action mechanism of the reinforced pipelines is to resist external force by increasing the strength and rigidity of the reinforced pipelines, but the pipelines can be subjected to shear force applied by an earthquake, and the pipeline can be broken if the shear force is too large.
