Directional Drilling technology is also known as horizontal directional drilling or even HDD, this process is a highly successful method of ensuring that the fitting of underground pipes and means that there is less disruption for many travellers that use the route where the work is being processed.
Many companies use this process to install telecommunication and power cable conduits. There are many other processes that may need to use the Directional drilling technology including water lines, sewer lines, gas lines, product pipelines and also environmental remediation casings.
Directional drills can be used for when the process cannot be completed such as crossing many of the countries waterways, busy roads, shore approaches or even where many other methods could get too expensive to do install them other ways.
Directional Drilling technology is now a very low cost process with very low impact being provided to the surrounding area, this drilling is cheaper that micro tunnels, jack and bore and also open trenching. The drilling can save disruption with many of the roads and walkways around the service area.
There are many advantages of using quality directional drilling technology including: less traffic disruption, lower set up and completion costs, deeper and longer installations can be provided, less time to complete the task, can go in many different directions and the process could be much safer for the environment.
When a task is begun that needs the directional drilling technology uses processes where the machine pushes into the ground, a hollow pipe is fitted onto the bore head and is inserted into the ground at the desired angle. With each insertion of drill pipe enters the ground a new one follows behind to form a join.
With softer soil on the ground the user drills with an angled bit on the drill with a rotated string. Once the bit is aligned into position the process is started with the pipe getting inserted into the ground.
A washover pipe can be installed into the bore hole to ensure none of the walls that have been formed will collapse at any point whilst they are being worked on. Once the hole is at least 25% larger than the pipe then the pipe can be fitted.
For some telecommunications or power cable projects, the drill pipe itself becomes the conduit and is left in the ground upon reaching the exit point. This type of installation is known as “drill and leave”.
Once the pipe is installed the exit and entry points are excavated if necessary and connections made as needed.
