UNDERGROUND UTILITY LOCATOR EQUIPPED WITH A TWO-STROKE PULSE TRANSDUCER

Abstract

With detailed large-scale topographic surveys of cities, especially when photographing executive master plans of industrial facilities, geodetic services perform work on measuring not only ground sites, but also - on detecting and localizing of under-ground utilities: water, oil and gas metal pipelines, power and telephone cables, etc. The search for underground communications by various services is carried out at use of special electronic devices for searching of underground communications: tracers, cable detectors.
A number of shortcomings have been identifi ed when operating these devices, including diffi culties in detec-ting and fi xing of pipes or cables in conditions of increased industrial interference, insuffi cient effi cacy and accuracy of the search process, high energy consumption, low level of ease of operation, due to relatively large weight and size parameters. A comparative analysis of currently used search devices has proven technical defects of circuit solutions, and has formed the basis for developing of an electronic circuit. A working model of an underground utility fi nder with a pulse converter has been produced. Main technical characteristics were obtained after testing.
The technical solution has been patented in the GU of the Intellectual Property Center of the Republic of Uzbekistan.
