The laying out of network lines in the installation of network infrastructure necessitates various processes, including utility locates, potholing, cable pulling, horizontal directional drilling, among others.
Utility locates is the process of determining the precise location of existing utility mains and lines underground. It is a necessary before undergoing any construction work so that they will not be damaged during the process. Potholing is the visual confirmation of the location of those lines. The process of horizontal directional drilling precedes the cable pulling process.
Horizontal directional drilling is one of three directional drilling types. The two other types are Oilfield Directional Drilling, and or Surface In Seam or SIS. SIS is the process of horizontally intersecting a vertical well to be able to extract methane from a coal bed.
Using the technology of horizontal directional drilling to install infrastructure cables saves financial resources and time. Since a greater part of the surface atop the area where the cables will be laid out will not be disturbed, communities around the area will remain relatively undisturbed, as well. There is lesser environmental disturbance and traffic is not interrupted. Horizontal directional drilling uses 75 drilling rigs. Up to 1.2 million pulling power or drilling thrust is used in the process. It can cross a length of 15 thousand feet or more to fit a pipe of 60 inches in diameter or less. This particular technology is greatly beneficial if the land surface that the drill will run across is protected lands. It will not be affected by erosion, dredging or ice movement.
