Horizontal Directional Drilling (or HDD) is a Directional Drilling Australia for the installation of Pipe Conduit and cable that utilizes a drill rig to install product pipe with virtually no excavations being necessary. The drill rig sets up and launches from the surface and pushes drill pipe into the ground to establish the pathway for the product pipe to be installed. The location of the drill pipe is monitored through the use of a locating device at the front of the drill head. Once the operator knows where the drill head is, he then controls what direction the drill head goes in by alternately thrusting and rotating the drill pipe in predetermined directions 12 o’clock for up 6 o’clock for down 3 o’clock for right and 6 o’clock for left to remain on a predetermined path.
Once this pilot bore is done and a path had been established for the installation of the product is achieved by drawing it back in to the hole the hole may need to be enlarged through a process called reaming. This process may be done as many times as is necessary to create a hole large enough to pull in the final product pipeline.
Key Benefits
- Safer construction method no open trench
- Minimal site restoration is
- Minimal environmental impact
- Reduced traffic congestion
- In many cases HDD is cheaper and faster
- Less disruption to the general public
- Faster process
SAFETY as the name implies we use Directional Drilling Australia techniques were ever possible as open trenches are responsible for an extremely high % of work injuries our onsite inspection consists of a full assessment of environmental, quality and HSE requirements, before any onsite works commence. We use site specific SWMS .
ECONOMICS Reinstatement costs associated with open trench excavation can be as high as 60% of total budget. Directional drilling needs only a single entry and exit point avoiding costly reinstatement.
ENVIRONMENTAL Because disturbance is kept to a minimum, the impact on the environment is reduced dramatically.
SPEED This method of operation is considerably faster than conventional trenching which means that the job is completed in many instances without people in the area being aware it has been done.
We have established a culture of safety within the company that promotes continuous operational improvements. Formal processes are in place to guide all facets of works.
SOCIAL COSTS The public has an ever-growing awareness of their rights and any effect on their habitat is being contested with ever-increasing vigor. Directional Horizontal Drilling is capable of passing by with little to zero effect on their property or verge.
TRAFFIC FLOW the social cost brought about by large numbers of people sitting for what amounts to hundreds of thousands of man hours in traffic jams has led to regulations to ensure that these disruptions are kept to a minimum which has led to increasing use of Directional Drilling Australia techniques.
SURFACE OBSTACLES As it is possible to drill as deep as 20 meters, surface obstacles Roads, Rivers, Buildings & other Utilities need not be a problem.
