CABLE PERCUSSIVE DRILLING
Danbars cable percussion & cable percussive drilling is one of the most commonly used methods for all kinds of geo-technical sites and ground investigations.
In the UK, depending on access limitations for our rigs and ground conditions, we can create boreholes up to 60m in depth.
The Danbar Drilling team are able to deliver extremely reliable and effective cable percussive drilling techniques which offer high levels of cost-efficiency as well as a range of technical benefits.
Thanks to our experience and versatile rigs, this method of drilling is ideal for use alone or as part of a wider drilling strategy on-site.
Whatever kind of borehole you are looking to create on-site, our industry-leading percussion drilling technology remains the perfect choice.
HOW DOES PERCUSSIVE DRILLING WORK?
Cable percussion drilling utilises a two-tonne winch, driven by a high-performing diesel engine.
Instances which require a wider borehole, we can swap the winch out for a four-tonne capacity alternative.
Typically, these types of rigs require easy and unimpeded access, but there are some occasions where modular percussion drilling rigs are suitable instead.
A Borehole is formed using either a shell (for non-cohesive materials) or a “clay-cutter” (for cohesive materials).
When the ground itself is very hard, or there are potential obstructions in the way, a chiselling tool can be used to great effect.
Sides of the borehole are supported with steel casing to ensure it maintains its shape.
Steel casing is lowered into the borehole as percussive drilling progresses.
Some instances, the steel cable itself will need to be driven into position to support the borehole sides.
Including when the hole is driven into gravel or sand, or into saturated zones which have not undergone extensive dewatering.
WHY IS PERCUSSION DRILLING USEFUL?
When performed by a team of professionals, percussion drilling can allow both SPT’s (Standard Penetration Testing) and Permeability Tests, including Falling Head Testing.
Both disturbed and un-disturbed samples of the surface materials can also be taken from the boreholes quickly and easily to allow the site engineer to log them.
They can then be transferred on to the client’s approved testing site. Within these boreholes, vane testing and packer testing can also be conducted.
These tests are essential if you are trying to find out more about the surface materials.
Results of these tests can make a major difference to your projects.
Information you can extract from the materials removed from these percussion-drilled boreholes can aid or reinvent your geotechnical designs for the area.
