Utility tunnel – an alternative method of routing underground utility lines and services Cable locator – an instrument used for detecting the presence and approximate location of buried services Utility repair tag – a color-coded tag to identify pavement restorer that sometime has a secondary purpose for utility location
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] During excavations, underground cables become at risk of getting damaged.
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 times the cost of an overhead power line. Above-ground lines cost around $10 per 1-foot (0.30 m) and underground lines cost in the ...
Jul. 12—Question : Our neighborhood has underground wiring. In January several houses lost power. HECO responded by putting in above-ground temporary hookups. More than six months later those ...
Reflections from soil layering are also present (dashed lines). Ground-penetrating radar (GPR) is a geophysical method that uses radar pulses to image the subsurface. It is a non-intrusive method of surveying the sub-surface to investigate underground utilities such as concrete, asphalt, metals, pipes, cables or masonry. [1]
A utility tunnel, utility corridor, or utilidor is a passage built underground or above ground to carry utility lines such as electricity, steam, water supply pipes, and sewer pipes. Communications utilities like fiber optics, cable television, and telephone cables are also sometimes carried.
