All You Need To Know About Horizontal Directional Drilling

Horizontal Directional Drilling also known as Directional Boring or HDD is a trenchless method of installing cables, conduits, or underground pipes alongside an arranged bore path that was invented way back in the 1920s. To minimize the impact on the adjoining areas a surface launched drilling rig is used. When making trenches or excavating is not a possibility then horizontal directional Drilling companies is the best solution to get the job done.

Directional Boring can effortlessly drill through sedimentary rock or solid rock although the use of HDD should be avoided if the soil is cobbled or made of incomplete rock layers. The equipment used will vary according to the size of the pipe that needs to be installed. The drilling head which is available in various sizes and types, based on what material the surface consists of, is made of heat treated high carbon steel. It helps in the removal of residual material. Medium sized rigs are used to easily and quickly install underground utilities without digging large trenches, blocking and disrupting traffic, as well as on wetlands.

How it works?

Horizontal rock directional drilling begins with the pilot phase where a test is done. The drill pit will create a test hole in the area with the help of drilling fluids and high pressure jets. A transmitter attached to the tip of the drilling tool sends information about the direction of the hole.

Once the pilot phase is completed successfully, pre-reaming of the pilot hole is done by carefully increasing the size of the pilot hole to fit the actual pipe. The directional drilling company will do this in stages so that the drilling fluid doesn’t leak to the surface or make the structure unstable. It will also help by lowering the pullback pressure when the pipes are installed and from wear and tear of the Horizontal Rock Directional Drilling equipment.

Uses

This method is the most sought after method for Power and Telecommunications cable conduits, sewer lines, oil and gas lines, water lines, etc. It can be easily laid across roadways, in congested areas or environmentally sensitive areas, waterways, and so on. As it causes minimum shock or disturbance to the nearby areas it is a very popular method. Also, it has a very predictable and concise schedule which makes horizontal rock directional drilling a very sought after method.

It is becoming a very popular method as it costs lesser than traditional methods, creates fewer traffic disruptions, quick completion time, environmentally safe and can dig deeper and longer installations. Once complete information about the existing structure of the area is given to the HDD operator he/she can analyze and make a plan for the installation without any damage to the existing utilities around. Many government agencies oversee their areas to stop uncontrolled digging, for the same reason the directional drilling company produces equipment that is in strict compliance with the industry standards and is therefore highly demanded. The use biodegradable rock drill oil makes them even more environmentally friendly.
