About Sonic Drilling
With a sonic head, drill casing and rods are brought to a vibration frequency of 100-200 Hz. These waves are transmitted from the head through the drill string to the end of the casing and reflected, causing the casing to stretch and thin, and to shorten and thicken 100-200 times per second. This intense vibration casues a very thin layer of soil directly around the drill rods to fluidize. The fluidized soil zone extends a maximum of 5 millimeters from the rod. The soil in the influenced area behaves like a fluid, which dramatically reduces the friction between the drill rod and the surrounding soil, allowing very rapid penetration. The same friction reduction applies to the inner surface of the soil sampling tool, and enables collection of very long sample cores (up to four meters). In addition to the vertical vibration, the sonic drill heads can also rotate to easily make up and break drill rods, and to cut concrete or asphalt.

Sonic Applications
The sonic drill head contains two or more synchronized eccentric weights that are driven by high-speed hydraulic motors, (6-12,000 rpm). The drill head is mounted in oversized isolation blocks to concentrate energy on the drill string. The movement of the eccentric weights brings the casing into a purely vertical vibration. With low pull-down or pull-up force. The casing can be driven and retrieved.

The Sonic Drill Rig systems have been designed to run a large variety of down-hole tooling to

Compact Sonic 10-C
The Compact Sonic Drill Rig (CS-10-C) is manufactured by AMS for Sonic Sampling & Supply and offers a great package where access is an issue and increased drilling production is paramount.

The CS-10-C provides high quality samples/cores and fantastic footage production. When using the CS-10-C, there are no cuttings or waste to dispose of, and limited use of drilling fluids in most conditions.
The CS-10-C puts out 20,000 to 28,000 pounds of force and the operator can select sonic vibration mode or rotation mode. Typical boring depths for 2-inch tooling are 100 feet and for 4-inch tooling to 50 feet.
It is safe, easy to use, and has relatively quite operation.

Compact Roto Sonic 17-C
The Compact Roto Sonic (CRS-17-C) is manufactured by AMS for Sonic Sampling & Supply. Where soil conditions are unknown or generally difficult, the CRS-17-C is the best choice.

With output forces similar to the CS-10-C, the CRS-17-C allows rotation and vibration simultaneously. This combination provides much higher cutting action down-hole, facilitating drilling in more competent semi-consolidated geologic formations.

When using the CRS-17-C, there are no cuttings or waste to dispose of, and there is only little use of drilling fluids in most conditions. It is safe, easy to use, and has relatively quite operation.

Typical borings are 3 or 6 inches in diameter and achieve depths of 200 feet and 100 feet respectively.

Compact Roto-Sonic 26-T
The AMS Compact Roto-Sonic 26-T (CRS 26-T) puts out 20,000 lbs. of force with simultaneous rotation and sonic vibration. It is ideal for collecting continuous cores of soil or rock, groundwater sampling, prepacked well installations, injection grouting , remediation work, and installation of geothermal loops.

With the capability of both rotation and vibration simultaneously, the CRS 26-T is designed to drill deeper, faster, and bigger boreholes. The combination of rotation and sonic vibration provides much higher down-hole cutting action, facilitating drilling in more competent semi-consolidated geologic formations. Where soil conditions are unknown or generally difficult, the CRS 26-T is an excellent choice. Options include auger attachments for installing larger traditional groundwater monitoring wells, wireline winch systems, stabilization jacks, water pumps, and more.
