Geotechnical Drilling
Drilling Methodologies Offered By ACS
-
- Hollow Stem Auger “HSA” is used to case off over burden while allowing for soil sampling through the auger at depth. This methodology accommodates for the use of sampling tools e.g., SPT and Shelby Tube.
- Casing Advance is used to quickly drill through and case off overburden and to get through competent rock layers. This method of drilling uses a down the hole hammer “DHH”.
- Coring is used to sample through competent zones when augers are unable to drill. This method is also used to continuously sample through rock.
- Conventional Air Rotary is used for small diameter borings, clean outs and abandonments.
- ACS’s Direct Push rig has auger and auto hammer capabilities
- Direct Push is used for sampling in tight areas e.g., inside of buildings.
Other Geotechnical Drilling Methods
The most common drilling method used in geotechnical engineering is the rotary drilling method. This method involves the use of a drill bit that is rotated and hammered into the ground to create a borehole. As the drill bit penetrates the soil, it creates cuttings that are brought to the surface for analysis. Rotary drilling is suitable for most soil types and can penetrate deep into the ground.
Another drilling method used in geotechnical engineering is the auger drilling method. This method involves the use of an auger, a helical screw-like tool, to penetrate the soil and extract samples. Auger drilling is typically used for shallow soil sampling and is not suitable for penetrating hard rock.
Coring is another drilling method used in geotechnical engineering, which involves the use of a diamond-tipped core barrel to extract a cylindrical sample of rock or soil. Coring is used when detailed information about the rock or soil is required, such as for the identification of rock types and the determination of their properties.
In addition to these methods, there are several other drilling techniques used in geotechnical engineering, including air rotary drilling, sonic drilling, and mud rotary drilling. Each of these methods has its own unique advantages and disadvantages and is chosen based on the specific requirements of the project.
Geotechnical drilling is a critical component of any construction project that involves building on or in the ground. The samples obtained through drilling are used to determine the strength, density, and composition of the soil and rock beneath the surface, which helps engineers design structures that are safe and stable.
Overall, the selection of the appropriate drilling method for a given project depends on several factors, including the soil and rock types present, the depth of the borehole, and the required level of detail in the data obtained. Geotechnical drilling is a complex and precise process that requires skilled professionals with specialized training and experience to execute properly.
