In the construction environment, a sonic drill can be an incredibly powerful piece of equipment on projects such as bridges and dams to ensure the structural integrity of such important structures.
By using the advanced casing system, once the investigation is complete the integrity of the site is still maintained as the casing remains as a placeholder to prevent any collapses of the subsurface structures. It is even possible for the sonic drill to penetrate traditionally tough materials such as limestone and dolomite, which usually pose a threat to standard rotary drills due to their geological qualities.
Being flexible is something that is required when conducting site investigations as the situation can always be challenging, which is why sonic drilling rigs can be adapted to fit different circumstances. A number of rigs can be fitted with caterpillar tracks, allowing them to be moved into position by an operator without the need for more heavy vehicles to pollute the site. There are also smaller sonic drilling rigs that can be interchanged depending on site conditions, which can all be planned with a preliminary site inspection to ensure the right tools are being used to deliver the best results possible.
Because sonic drilling can be done without fluid or air, it is often used for things such as earthen embankments where it is not possible to use traditional methods, giving it a wider range of uses outside of the commercial industry.
How does Sonic Drilling work. Share this page. Main information Sonic Drilling Technology Sonic drilling is a soil penetration technique that strongly reduces friction on the drill string and drill bit due to liquefaction, inertia effects and temporary reduction of porosity of the soil.
Sonic Mechanics When you engage the Eijkelkamp SonicSampDrill drill head, the entire drill string is brought to a vibration frequency of up to Hz.
Less power, fewer problems Because of the reduced friction on the length of the drill string, sonic drilling needs less power to achieve the same effect as conventional drilling. Sonic drilling is clean drilling There are situations where you want to avoid the usage of drilling mud, air or even water while drilling.

Once fluidization begins to occur, very rapid penetration rates are possible and core barrel or casings can be efficiently advanced into subsurface formations. Sonic frequency is used to advance the core barrel. This can often be done without the use of drilling fluids. After the core barrel is in place, casing is sonically advanced over the core barrel, protecting the bore hole's integrity in loose unconsolidated ground.
