A hydro excavation technique is one of the most modern techniques for excavating. It involves the use of highly pressurized water along with creating a vacuum that will take out the soil and rock or gravel from deep underneath the soil. If you need hydro excavation then it is better to hire a hydro vacuum excavation service provider as they have qualified engineers and the know-how and technical expertise to carry out the job along with the highly advanced machinery to undertake the process.
History Of Hydro Vacuum Technique For Excavating
The origin of modern-day technique used in hydro vacuum excavation started for oil and gas mining. The efficient technique came out due to the existent challenges in which the soil would freeze and the traditional process for excavating and mining would not work. Today mining companies and other excavation agencies will get partnered with a hydro vacuum excavation service provider and team up for a large and challenging excavation project.
The Principle Of Hydro Vacuum Excavation
The principle that a hydro vacuum excavation service provides will work is based on combining highly pressurized water with an air vacuum.
The system will cut open the soil and then vacation will lift the slurry and debris from within the area. The debris is then transferred to a debris tank unless you get help from a hydro vacuum excavation service provider.
Now as you can understand that the main principle behind taking out the slurry and debris will depend on the formation of a vacuum. For this, the engineers have developed two efficient processes.
One is a fan system and the other one is a displacement blower.
The fan system will be turned on and this will naturally suck out the debris from deep underneath the pothole.
It is a cheaper process too. The technique has been recently developed in the last couple of decades and it is a more efficient technique that is used in mining and potholing or for installing light or signage poles.
It is the process that employs highly pressurized water and then creates a vacuum for transferring soil and other debris. The taken-out soil and other substances are transferred to a debris tank.
This is more of a non-destructive technique for the excavation of soil ensuring less damage to the surroundings with the help of a hydro vacuum excavation service provider.
The other system that commonly a hydro vacuum excavation service provide will employ is the displacement blower technique.
In this technique, the excavation can be done several meters deeper than the fan system technique. Here the main difference is that the vacuum pressure created by the displacement blower is way stronger than what you will get out of the fan system.
Benefits
Fewer hazards caused to the environment Of course when a hydro vacuum excavation service provider will employ the hydro vacuum technique then this will cause less damage to nature such as low soil erosion, lesser chances of underground water pollution, and lesser bedrock damage.
Highly efficient and way faster than traditional excavation techniques It has to be said that the technique of both the fan and the displacement blower technique is way faster than the traditional and age-old obsolete methods of excavating.
Drawbacks
The only problem is that this is quite a slow technique.
Remember, this is a form of technology that is done for faster excavating. The only problem with this technique is that you cannot excavate too deep or else the fan system will just not be able to form the necessary upward vacuum pressure to take out the slurry.
