What is the sonic drill about? How does it stand out among other methods of drilling employed by the industry? Do you have higher chances of achieving your project drilling goals if you will try to take advantage of this method?
Sonic drilling is a qualified soil penetration technique. This drilling method allows for the reduction of friction on the drill string and drill bit which is usually induced by inertia effects, liquefaction, and the soil’s temporary reduction of porosity. The combination for which allows for easier penetration of a wide array of soils. Employing this technology will work to your project’s advantage in such a way that it allows your drill bit to make faster penetration even on different types of bedrock.
The oscillator, which can be found inside the drill head will generate high-frequency energy. This resonant energy is then directed into the drill string. While the drilling process is ongoing, the resonant energy will go together with the rotational movement. It will be helpful in the even distribution of the energy which creates an impact on the drill string and drill bit tooling.
As for the drill operator, he can put some level of control over the sonic vibration amount that the drill head will generate to match the force required to achieve an optimal penetration of bedrock and soil formations.
Sonic Drill Mechanics
By engaging your sonic drill head, you are bringing the entire drill string to a favorable vibration frequency and this can even reach a maximum amount of 150 Hz. This happening can cause a thin zone to lose structure. This will help in lowering the amount of soil friction and drill cuttings to eventually become liquid in form, enabling it to be flushed out from the borehole with great ease. Have a peek here.
The drill bit will create vibratory actions that will render the soil to lose hold of its structure. While this is happening, it will cause the porosity and density of the soil to change. This way, your drill cuttings, and soil will move in the sample barrel, and on the drill string to help in advancing the tooling, freely.
The liquefaction and inertia effects enable you to collect long and continuous samples. Due to the vertical high-frequency movement, the drill string stays extremely straight with very little deflection.
Less Power, Fewer Problems
Due to the reduced strength of friction that is normally found on the drill string’s length, it will render sonic method of drilling to consume lesser amounts of power to deliver the same effect that conventional drilling techniques make. This is one of the most unique characteristics of sonic type of drilling, it will keep torsional forces from occurring on the drill string.
Another notable advantage of the sonic high-frequency application is the ease of drill string retrieval. It remains so even when under expanding boulders or if the conditions are a way to difficult to handle. All casings, tooling and drilling rods are pulled easier and faster.
Sonic Way is a Clean Way to Drill
There are certain kinds of drilling projects that will have you veer away from the use of drilling mud, or even water while drilling process is ongoing. In sonic drilling, there is absolutely no need for drilling mud or air while drilling. This explains the reason why this form of drilling, sonic, has become the drilling method of choice when it comes to geo-construction, geotechnical, and even for environmental applications.
