Utility
locating can be taken as a service to locate/detect underground
utilities before initiating the actual digging process. These can
detect as well as identify buried utilities, preventing possible
digging accidents, which fosters safer excavation methods.
Various
methods of top utility locating companies before digging are
mentioned below-
CONVENTIONAL
METHOD
Radio
location - This process makes use of radio waves to find the
location of useful items. Electromagnetic (EM) equipment are used in
this technique, which consist of transmitter and receiver. EM signals
are mostly emitted from metal pipes as well as cables, which are
detected by the receiver.
NON-CONVENTIONAL
METHOD
Ground
penetrating radar (GPR) - This EM method that is used by
the underground utility locating services to augment other
locating techniques. This geophysical method utilizes radar signals
to image the subsurface. The GPR system comprises of an antenna and a
receiver, and also a profiling recorder (to process the received
signal). This technique has the ability to generate 3D images of
sewage, pipes and water mains.
Acoustic
locating - It makes use of sound energy to determine the distance
and location of an item. This type of technique is very often used
detect and trace non-metal water lines. Acoustic locators find
application in identifying locations of plastic gas lines.
Magnetic
locators - This technique is often used to locate buried metal
different than pipes. It is most commonly used to locate UST
(Underground Storage Tanks).
Consider
all these methods and make sure to use a locating service provider
that employs UTA certified professionals.
