What is directional boring

The second step is to pre-ream the pilot hole and enlarge it to a size sufficient to safely install the product lines. A reamer is pulled back and rotated while pumping drilling fluid to cut and remove solids to enlarge the hole. Pre-reaming speeds will vary depending on existing soil conditions and the amount of cuttings that are removed from the hole. Bentonite and other additives will be used to ensure a clean and stable hole. This will help with the stability of the bore hole and with fluid loss or infiltration.

Additives such as polymers are used to help break up the clay soils. A more evenly mixed drilling fluid will prevent any blockages inside of the bore hole. After the bore path is enlarged, the conduit is simply pulled into place by the directional drill rig.

This method of installing conduits has many benefits that include less disruption of commercial activities, less disruption of traffic, less site rehabilitation, and directional drilling can also be used to avoid damage to wetlands, streams, and for river crossings.

Lastly, the pipeline is pulled into the hole, which creates a continuous segment of pipe underground. Directional boring or horizontal directional drilling is also a method that is used in the installation of utility pipelines and conduits. Underground boring contractors mostly use HDD for crossings under rivers, roads, and existing structures.

Directional boring or horizontal directional drilling is a good way to get utilities from one point to another without destroying any of the existing ground or obstacles that exist between the two points. Trenching, or open cut, is the most common way to install and connect utilities. However, it does have some limitations. HDD contractors use directional boring in the same situations where tranching is the original plan, but when there is need, it can also be used to go under roads, sidewalks, rivers, and houses.
