HDD companies continue to be challenged to improve productivity, safety and environmental stewardship in operations, also: See the video below for an example of a drilling project with our Gyro Steering Tool.Horizontal Directional Drilling (HDD) has become one of the fastest growing trenchless technology construction methods for the installation of underground pipelines and conduits. The modules offer a solution for every situation, that make drilling projects possible that were previously unthinkable. Modularīecause of our modular and state-of-the art design, it is possible to add specific add-ons to the drill, like GPS track and Radar Intersect. At the same time, the tool is not affected by magnetic fields from for example railways and cables. The accuracy of the tool is 0.01° in pitch and 0.04° in azimuth. Highly accurateĪs we just indicated, our tool is very accurate.
Our system has been developed in such a way that there is no need for magnetic fields or beacons to determine the position. Within an hour of arrival at the drilling rig, we are ready to start the directional drilling process. Furthermore, our system has more advantages to make horizontal directional drilling as efficient as possible: 1. Our Gyro Steering Tool makes it possible to determine the exact position of the drill. This innovative system is based on Gyro technology.
If the drill needs to change direction, we use our self-developed steering tool. This ensures that when the pipe rotates, the bore goes in a straight line. An asymmetrical drill head is used in this process. Sometimes the pipeline is provided with a ballast pipe to absorb high pressure.Ī simple principle is used to control our directional drill process. When the reamer has done its job, it then gets connected and replaced by the production pipe and a final reamer. Pulling the production pipe: In the final phase, the production pipe gets pulled. During this process, the reamer pulls a pipeline behind it that is provided with drilling fluid to prevent it from collapsing.
This reamer gets pulled back to widen the drilling hole. In addition, it immediately becomes possibly to remove excess soil.Įxpanding the drilling hole: After the pilot drilling, the drill gets removed and replaced with a reamer. Bentonite is poured into the hole from the surface. Pilot drilling: During the first phase, a drilling head that is hollow inside is pushed through the ground via a rig. Horizontal directional drilling takes place in three stages: How does horizontal directional drilling work? Horizontal drilling is used for the placement of underground infrastructure. Horizontal directional drilling, also called HDD, is a method that is used for trenchless drilling.

At Brownline, we use our self-engineered Gyro Steering Tool for horizontal directional drilling. Horizontal directional drilling is a trenchless technique used for the construction of underground infrastructure.
