A Complete Guide on Directional Boring

Directional Boring or Horizontal Directional Drilling has replaced all the traditional drilling methods. It has several benefits and has found its way into applications like waterways, roadways, and more. This technique is time-saving and requires less resources comparatively. This piece explains how the entire drilling process is performed while highlighting its benefits as well.

  1. A Complete Guide On Directional Boring

  2. Introduction ●Directional boring, popularly known as (HDD), facilitates sideway drilling, thus, providing more exposure to the surface area. ●It is usually preferred in those installation processes where trenching or excavation cannot be implemented. ●Industries opt this technique in installation of various pipes, conduits, power cables, water lines, etc. while causing minimum harmful impact on the environment. ●Major applications include crossing waterways, shore approaches, roadways, environmentally sensitive areas, congested areas, etc.

  3. Horizontal Directional Drilling (HDD)

  4. Benefits ● Cheaper than traditional drilling techniques ● It enables deeper installations ● Quicker to implement ● No requirement of access pits ● Causes minimal hazardous impact on the environment ● Provides maximum directional capabilities ● Maintenance cost incurred is quite less ● Suitable for diverse soil conditions & surfaces (river crossings, roads, landscapes, etc.) ● Power supply requirement is comparatively less ●Labor force & machinery equipment used are significantly shortened.

  5. Procedure Prior to drilling, the surface area (constituents and properties of the soil) is examined closely. Next, existing underground communication lines are removed and selective soil probing is carried out.

  6. Later, the results are combined and studied to decide which path and tactic should be chosen for bore hole laying. It is essential to choose an optimum location for drilling equipment on the site. Also, measures should be undertaken to ensure safety of all the workers and other people around.

  7. Four Stages of Drilling Procedure 1.Drilling a Pilot Hole A rock-cutting tool is used to perform the drilling work. The drilling head along with a transmitter fitted on it allows to operate and control the drilling process. A fluid is filled in the head to reduce friction and provide more stability to the bore hole. Visual information about the position, angle and azimuth of the drilling head is showed on the locator display that receives information via the transmitter.

  8. 2.Enlargement of Pilot Hole After drilling a pilot hole, it is enlarged with the help of a back-reamer which is attached to the drill string. The reamer is pulled back to the machine, from the exit end of the tunnel, enlarging the pilot hole to the required diameter.

  9. 3.Pipeline Pulling A pipeline string is prepared for pulling on the opposite site from the drilling machine of the bore hole. To prevent the pipeline from rotation, a swivel is attached to the back- reamer; then pipeline is attached to this swivel with the help of a gripping device. 4.Final Stage Documentation on the operation scheme is prepared to describe the link between pipeline and landmarks. It provides an overview on where the actual pipeline is positioned on different planes.

  10. We-Bore-It has been providing directional boring & trenching services to the Cable, Telecommunications and Wireless industry since 1990. The company was founded with the idea of uniting multiple contracting companies under one umbrella company. After years in the industry, and valuable feedback from customers and partners it became clear that they wanted us to expand our operations from that of local to that of a regional or even nationwide operator. Our goal is to offer our residential and commercial customers a service that focuses on all their underground construction needs.
