Install Underground Wire Using Horizontal Directional Drilling (HDD)

During the 1950s, 1960s, and 1970s the need for water and sewer services grew. The use of horizontal directional drilling began as a practical alternative to conventional trenching methods. It was discovered that there might be potential for using drilling technology to enhance the efficiency of installing cables and conduits underground. This is how the use of Horizontal Directional Drilling (HDD) began for underground wire installation.

Nowadays, construction projects that involve installing underground utilities are carried out with more efficiency due to the evolution of technology and techniques. The purpose is to make the process of installing underground utilities more convenient, less disruptive, environment-friendly, and budget-friendly.

By reading this blog, you will be able to learn about Horizontal Directional Drilling (HDD) and its use for underground wire installation.

Understand Horizontal Directional Drilling (HDD)

The steerable trenchless boring method for installing underground wires, pipes, and conduits in a shallow arc along with a prescribed bore path is called Horizontal Directional Drilling (HDD). The process of installation is carried out by using a surface-launched drilling rig. The method is used when trenching or excavating is not a practical decision for installing underground utilities.

That’s all you need to know about Horizontal Directional Drilling (HDD) to have an understanding of the overall concept of the trenchless method. Now consider knowing about the use of the HDD method for underground wire installation.

The use of Horizontal Directional Drilling (HDD) for installing underground wire?

You have already got to know the HDD trenchless method of installing pipelines, wires, and conduits is used where traditional open-cut excavations are not feasible for logistics and environmental reasons. It could be a special technique for the installation of underground utilities which may save a considerable amount of time and money.

Now let’s understand the process of Horizontal Directional Drilling. The procedure usually consists of three main stages. These stages are…

  • Pilot-drilling 
  • Reaming 
  • Pipe pullback

Know about pilot drilling

This is the very first stage of the process of the trenchless method. At a pre-determined angle, a pilot hole gets installed from the surface along a prescribed path. During the pilot bore a transmitter and a receiver device are utilized to be able to locate precisely and steer the drill string underneath the surface. Once all the tasks are performed accurately in this stage, the technicians move to the stage of reaming. So let’s understand about reaming.

Know about reaming

Reaming is considered the second stage of the process. Completing this stage is necessary to get into the last stage. In this stage, the pilot hole gets enlarged to achieve the required size and that’s all. Reaming is usually performed in the stage until the final desired diameter of the hole is achieved by the technicians.

Know about pipe pullback

Pipe pullback is the last stage of the process of the trenchless method, so that is why it should be carried out carefully for successful completion. In this stage, the pipe gets connected to the drill string and then pulled back from the exit pit side towards the entry pit side. This process of pulling is done on the same pre-reamed path.

So, these are the stages that are the basics of the HDD method that you should know before hiring a technician for execution. By following this method underground wire installation is carried out in construction projects. 

Reasons to choose the HDD method for underground wire installation

There are many reasons for choosing the HDD method for underground wire installation. Some of them are the major reasons which you will get to know.

The three main reasons for using the HDD method are mentioned below:

  • No disruption of the surface level – Using the HDD method is considered the best alternative to the traditional method of drilling because this new technique does not disrupt the surface level. 
  • Less time-consuming process – To carry out the method of directional drilling, high-tech equipment and tools are used which increases the efficiency to finish the objectives in a lesser time. 
  • Budget-friendly – Just because the method does not disrupt the surface level, it cuts down the expenses of recovering the surface of the land. As a result, the Horizontal Directional Drilling (HDD) method has also become budget-friendly.

Along with these advantages, there are other beneficial factors that are increasing the demand for the HDD method. Some other reasons like environment-friendliness, a safer method, and many more…

Conclusion  

So now you know about the HDD method for underground wire installation, it is your time to hire a professional technician who can get your project done in the most efficient way. So wait no more and choose the HDD method for the successful completion of your project.
