Sonic drill rig manufacturers are the best people to go for if you want to learn anything about sonic drilling. Technically speaking, we qualify them as the people who are “in the know” when it comes to everything about it. Most of the time they will qualify sonic drilling is a high power ground-penetrating technique. It allows you to effectively dig into the earth and obtain core sampling.
One of the highlight features of sonic drilling is that it significantly reduces the amount of friction it will produce. Friction will occur between the drill bit and the drill string and is brought about by liquefaction, reduction of the porosity of the soil and inertia effects. Add them all together now, and you will have a good recipe for digging through all the different types of ground soil.
Sonic Drilling and Its Mechanics
When your drill head is fully engaged, it brings your drill string to a vibration frequency which may as high as 150 Hz.
By engaging the sonic drill head, you are bringing the entire drill string to a vibration frequency that is reaching up to 150 Hz. This will render the drill bit and string to lose hold of its structure. With this process, the friction between the soil and the drill is lessened, but not completely taken away, and becomes fluid and can be flushed or washed off with greater ease.
The drill bit and its vibrations will cause the soil to lose structure, changing in the process its porosity and density. This will render the cuttings and the soil to move and occupy the sample barrel and then go up the drill string, helping in a way the tooling advance freely.
The effects of inertia and liquefaction enable you to collect continuous and long samples.
The vertical movement of the drill string remains extremely straight and with very minimal deflection.
Less Power, Fewer Difficulties
If the frictional strength is greatly reduced, the subsequent power needed by sonic drilling to achieve the same outcome offered by conventional drilling will also decrease. This is one of the few highlighting features of sonic drilling. It is also taking on a significant role in making sure that torsional forces will occur on the drill string.
The seamless retrieval of the drill string is also another sonic drilling advantage, regardless if you are working in quick expanding clays or even in the midst of boulders, or any other similar and challenging conditions that are deemed as pretty normal in a drilling project.
Sonic Drilling Means Nothing Else But Sonic Drilling
There would be drilling projects that you know will have no need for the involvement of water, drilling mud or even air while drilling work is ongoing. Engaging oneself to a sonic drilling project does not warrant that you will automatically need drilling air or mud in order to complete the job and get things done right the first time. This is among the practical reasons why expert minds in the business prefer and made it as a method of choice for their geotechnical, geo-construction and environmental applications.
For example, environmental drilling projects usually won’t have a hard time reaching their goals but by taking advantage of sonic drilling, they are able to take a step closer to their goals. Their goals become more actionable and attainable than previously thought.
