Trenchless technology, which is also called “no-dig” technology is the science of installing, repairing and renewing underground cables, pipes, ducts other utilities with the use of techniques that eliminate the need for excavating the ground. And for this and other good reasons, it has been embraced by most companies that are into civil construction.
Building a building, house or shopping center is the dream of many companies and people. It is a goal that when done indicates a high status and also that one is capable of doing great things. That is why civil construction is one of the favorites in the whole world.
Trenchless drilling or horizontal directional drilling (HDD) is a method used in trenchless technology, in which underground utilities like cables, pipes and so on, are installed with a greater accuracy along a predetermined path using a highly specialized trenching machine. This causes a minimal destruction as it is done without unearthing the ground surface.
HDD is a trenchless construction method that, in the simplest terms, involves drilling a path underneath a river or other obstacle (like a road) and basically threading the pipeline underneath. Horizontal drilling is the process of drilling a well from the surface to a subsurface location just above the target are called kick-off point, then deviating the good bore from the vertical plane around a curve to intersect the reservoir at the “entry point” with a near-horizontal inclination.
Ground-penetrating radar (GPR) is a geophysical method that uses radar pulses to image the subsurface. This nondestructive method uses electromagnetic radiation in the microwave band (UHF/VHF frequencies) of the radio spectrum and detects the reflected signals from subsurface structures. Utility locating is the process of identifying and labeling utilities which are underground. These include lines for telephones, natural gas, fiber optics, electric grids, traffic lights and wastewater pipes. Different detection and location methods are being used for the different types of underground lines. One of the safest ways of modern detection is through the use of ground-penetrating radar (GPR).
