AI Technical Summary
Existing buried polyethylene pipeline positioning technology is not accurate enough, making it easy to be damaged during construction, posing natural gas leaks and safety hazards, especially since non-conductive and non-magnetic PE pipelines are difficult to position effectively.
A positioning method based on pulsed acoustic wave excitation is adopted. A short-time pulse signal of 500Hz-1kHz is generated by striking the ground. The reflected wave signal is detected by a signal receiving device, and the pipeline location is determined by filtering, amplification and cross-correlation function superposition algorithm through a signal processing module.
It improves the accuracy of buried pipeline positioning, can accurately identify the location of non-metallic pipelines, reduce construction damage, and ensure the safety of urban construction.
