Safety Monitoring and Early Warning System for Buried Pipeline Crossing Fault
Hou Wang-gan · Pipeline Technique and Equipment · 2015
Long-distance buried pipeline crossing fault is prone to crack,dislocate and buckle,so the implementation of pipeline security monitoring and early warning can not only offer the earthquake quick report,but also provide basis for the safe operation of the pipeline condition assessment and risk tube section of the emergency rescue. Through monitoring of the force of fault hazard-affected body,pipeline of hazard-affected body and soil mass on pipeline,thus forming the function of ground acceleration early warning,fault displacement early warning,pipeline strain early warning,pipeline leakage warning,location of pipeline inspection,real time display of deformation and stress of pipe,the dynamic change of the relative displacement and the interaction force of the pipe soil. It can effectively reduce the damage caused by the sudden disasters and the occurrence of secondary damage.
