It’s abbreviated as HDD and is also referred to as Directional boring. This is a trenchless method that is used in the installation of underground pipes, conduits as well as cables. It uses a surface launched drilling rig to dig the surrounding area while causing minimal impact to the area. It’s the preferred method in situations where trenching/ excavating are not practical solutions.


Directional boring is no different from any other method and requires for a certain technique to be used. As said previously it’s best used when installing infrastructure such as power and communication cables, pipelines. The method can be used in environmentally sensitive areas and can even be a cheaper method to be used when the other methods are considered costly or expensive. HDD has been used extensively in urban areas as it helps avoid the need of extensive open cut trenches. It’s important to note that the contractor needs complete information about the utilities in the city before beginning the operation as it helps avoid the damage of these utilities.


The directional boring provides a number of advantages to the other methods available. To begin with it doesn’t disrupt traffic. It’s important to note that some traffic can be disrupted when using this method, but not as much as the other techniques. It’s less expensive. It’s still pricey for the everyday person, but when compared to the other methods available, it’s definitely less costly. Some other advantages of using the HDD technique are such as shorter completion time and it’s safer for the environment.


There are some factors that ultimately determine the equipments that will be used for the process. Factors such as the outer diameter of the pipe, ground conditions and the surroundings play a role on deciding the horizontal direction drilling tooling process that will be applied. Some of the main equipments used are such as the drill, mud reclaimer, excavator, pumps and hoses, a drilling mud recycling system, mud tanks, MTI equipment, Reel trailer and much more. As said previously, it ultimately depends on the job being done and the factors stated above.


There’s a lot more to the process of directional boring, but it all starts with the receiving hole and the entrance pits. These pits are important in allowing the drilling fluid to be collected and reclaimed. This helps reduce costs and minimize waste. It does take a while to explain the entire process, but it mostly involves those two pits that start the entire process.


You might wonder how they locate and guide themselves through the bore path. There are equipments that are used to help with this. They are the walk over locating system, wire line locating system and gyro guided drilling. In brief, the first system uses a transmitter behind the bore head to get readings on the temperature, angle, rotation as well as direction. The second method uses a magnetic guidance system to verify the location. The third system is fully autonomous and considered the most accurate of the three. Now you know a bit about HDD, this doesn’t mean you’re an expert always call the experts for support when needed. Horizontal Directional Drilling supply tools can be found online as there are broker that sell these equipments.
