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.
Horizontal Directional Drilling (HDD) is also referred to as Directional boring and is a trenchless technique used for installing conduits, underground pipes, and cables.
How Horizontal Drilling Protect the Environment:
“There is absolutely zero impact in regards to the environment because we are going underneath (the water) so there is no surface disturbance whatsoever for the construction and installation. “It’s really the most environmentally friendly method of installation across a water body because there is no physical activity inside the water, “fish habitats are not disturbed.” Riverbank stability is another benefit associated with the HDD construction method.
How it Can be Applying:
The process is multi-staged and the first step involves creating an entrance pit with a receiving hole. A pilot hole is then drilled through the designed path, after which the hole is enlarged (reamed) with a larger cutting tool known as the back reamer. The reamer is determined by the size of the pipe to be pulled back through the hole. In the next stage, a casing pipe is placed in the enlarged hole by using the drill stem. A fully automatic gyro-based drilling mechanism is used by advanced HDD machines.
What is Fiber Cable:
A fiber optic cable consists of a bundle of glass threads, each of which is capable of transmitting messages modulated onto light waves. Fiber optics has several advantages over traditional metal communications lines: Fiber optic cables have a much greater bandwidth than metal cables.
How Deep the Fiber Lying under the Sea:
Depending on where the cable is being laid, it might differ in thickness. Thinner cable systems are used for shallower ocean depths, whilst thicker cables are used for deep ocean beds, typically up to 20,000 feet.
Techniques that you Should Keep in Mind:
For cross river fiber lying you have to make sure that techniques already be used and improved best and that technique according to the river’s local geology.
