Collins Alexander Demidov); туннель для проводок (A utility tunnel, utility corridor, or utilidor is a passage built underground or aboveground to carry utility lines such as electricity, water and sewer pipes. Communications utilities like fiber optics, cable television and telephone cables are also sometimes carried. Utility tunnels are common in very cold climates where direct burial below the frost line is not feasible (such as in Alaska, where the frost line is often more than 18 ft (5.5 m) below the surface, which is frozen year round). They are also built in places where the water table is too high to bury water and sewer mains, and where utility poles would be too unsightly or pose a danger (like in earthquake prone Tokyo). Tunnels are also built to avoid the disruption caused by recurring construction, repair and upgrading of cables and pipes in direct burial trenches.
