Drilling Elfers The use of Air in Geotechnical Drilling

/in , /by

Geotechnical drilling is often a very mechanical process in the sense that much of the work is done thanks to the work of machines. These machines are the drilling rigs and drill bits that are able to break through all different types of soils and sediments of different hardness when performing geotechnical drilling. Elfers residents might think that these machines do all the work, as they do a majority of it, but depending on the geological conditions and the reason for drilling in the first place, there are many other aspects that can help or affect the process. For example, air is often an overlooked aspect of geotechnical drilling when professionals are out working in the field or on a construction site.

Air Rotary Drilling

Apart from gaining access to something underground with geotechnical drilling, Elfers residents should know that another task that some drilling professionals need to take is sample collection. Depending on the location of the drilling task, some samples that need to be collected are hundreds of feet below the surface, when it may be difficult to get an accurate boring sample back up. In this instance, a drilling professional might use the technique known as air rotary drilling. Drilling professionals will use compressed air to force bits of rocks and sediments that have broken up with a drill back up to the surface without a need to send additional equipment down the drilled hole to collect the samples.

Air Percussion Drilling

Another aspect about drilling deeper into the ground is the fact that the farther professionals have to go when drilling, Elfers drilling professionals risk putting mechanical wear and tear on their equipment. This could eventually cause the equipment to break or not work property. In order to make it easier on the machinery, drilling professionals might opt to use a technique known as air percussion drilling. This method utilizes compressed air to force a hammer bit deeper and deeper into the ground in order. Like air rotary drilling, this method can also use air in order to force samples back up to the surface in order to be analyzed.

Environmental Drilling Elfers How do Rocks Affect Environmental Drilling?

/in , /by

Rocks are a natural feature for many types of terrains and geological conditions that there is rarely ever a chance where geotechnical drilling professionals will not have to deal with them at some point or another, including drilling tasks that are considered to be a part of environmental drilling. Elfers residents might think that any drill is going to be able to break through any rock with enough force and enough time applied to drilling, but this is not always true. There are many types of rocks that have their own unique characteristics and properties that can make it easier or harder to drill into for geotechnical drilling professionals.

What is Rock Hardness?

One of characteristics of different types of rocks that is unique per mineral is what is called hardness. Hardness is defined as a rock’s scratch resistance, and a rock that has more hardness is said to be stronger with more scratch resistance. In the state of Florida, most of the rocks that are dealt with have relatively low hardness levels, making them easy to drill into when performing environmental drilling. Elfers residents should also be aware that this can also be a big reason why sinkholes are so common here, because the rocks can easily be broken down.

How to Get Around Rock Hardness with Drilling Equipment

Just because a rock has a high-level hardness does not mean it can’t be broken down or drilled into. In order to get through a rock with high hardness while performing geotechnical drilling, Elfers geotechnical drilling professional’s have to use special drill bits that have a higher hardness than the rock they are drilling though. For example, diamond is often the strongest kind of drill bit used because there is no other sediment that is harder than diamond. Keep in mind that using a drill bit that is too strong for a rock can also have adverse side effects to a drilling location and the equipment that is being used.

Geotechnical Drilling Elfers How Important is Water to Geotechnical Drilling Professionals?

/in , /by

It is not uncommon for someone to imagine that geotechnical drilling companies are going to be working with drilling into the ground, it’s all in the name. This also leads many people to believe that these professionals would never be doing something where water is a big factor, but this is not true. When it comes to geotechnical drilling, Elfers residents should be made aware that many locations and services oftentimes have to be done in areas partially or fully submerged in water. It is also quite likely that a geotechnical drilling company would be collecting groundwater samples to be analyzed and tested.

Drilling isn’t Always Done on Land

Even though the services fall under the broad category of geotechnical drilling, Elfers residents should be made aware that there are often jobs that need to be done in a large body of water or off the coast in the ocean. This is very important for the many structures that need to be built on or near a body of water. For example, if a local city or town wants to build a bridge over a water area, a professional company is going to have to make sure that the foundation of the bridge is secure which stays submerged under the body of water.

What Kind of Structures are Dependent on a Water Source?

Bridges are one common structure that need to be secured within a body of water, but there are many other structures that are affected by water within geotechnical drilling. Elfers residents might have a well in their yard, which has to be drilled deep enough to hit water in order to have it be used by the homeowner. Different types of docs and piers are also structures that need to be secured under the surface of a body of water in order for it to be used properly and safely. Water is much more important to services within geotechnical drilling that what many people are led to believe.
