Utility locator tool in use with spray marking can for marking location Utility location is the process of identifying and labeling public utility mains that are underground. These mains may include lines for telecommunication , electricity distribution , natural gas , cable television , fiber optics , traffic lights , street lights , storm ...
They are especially beneficial to densely populated areas, particularly those locations where overhead cable posts are unavailable or are not ideal. [3] Locating underground cables—as well as other underground facilities—is an integral pre-excavation process mandated by laws and guided by a number of industry standards. [4]
An underground cable marker. Markers are put at regular intervals to show the route and warn of the hazard of digging into the cable. Undergrounding is more expensive, since the cost of burying cables at transmission voltages is several times greater than overhead power lines, and the life-cycle cost of an underground power cable is two to four ...
Utility repair tag (also known as A-tag, asphalt tag and road cut medallion) is a plastic color-coded pavement marker embedded in the top surface of an asphalt utility cut restoration to identify the responsible party of that pavement repair or patch. [1] [2] The tag is not to be used for identification of an underground utility location. [3]
Detectable tape or Underground warning tape is a conductive tape typically applied over buried utilities made of non-conductive materials such as plastic, fiberglass, or cement. It is used because most utility location methods work best on conductive objects, and hence may easily miss structures made of non-conductive materials.
A utility pole, commonly referred to as a transmission pole, telephone pole, telecommunication pole, power pole, hydro pole, telegraph pole, or telegraph post, is a column or post used to support overhead power lines and various other public utilities, such as electrical cable, fiber optic cable, and related equipment such as transformers and ...
Borehole radars utilizing GPR are used to map the structures from a borehole in underground mining applications. Modern directional borehole radar systems are able to produce three-dimensional images from measurements in a single borehole. [8] One of the other main applications for ground-penetrating radars is for locating underground utilities.
A chart showing different underground utility locating cart systems. 3D mapping can be accomplished when several individual passes are combined and interpolated. All of the systems and antennas manufactured by US Radar are capable of having their data presented in 3D format with the appropriate software packages.
