Industry Best Practices for Vacuum Excavation
In the process of digging, there are a lot of techniques in use today. Some of these methods are old-fashioned in nature, but others are modern. On account of drilling companies using these new methods, digging has become easier, faster and safety is more assured than in the past. An example is the vacuum excavation method that uses either water or air in the process. By noting the following practices, you are assured of an efficient excavation.
Where there is soil that is hard-packed and heavy, air is not a good choice as a vacuuming agent. In such cases, hydro excavation, or the use of water is most preferred. In contrast, where the soil might be loose, sandy and with a lot of gravel, dry or air excavation is advised. Safety wise, dry excavation is the better alternative because it will not damage older pipes and brittle electricity wires because it has no water pressure like in hydro excavation.
In the excavation process, the sizes of the vacuuming pumps to be used to store air or water should be noted in relation to the size of the trucks to be used. If the required vacuum power is to be sufficient enough, then the size of the air or water tank must match the size of the pump used. This implies that if you require a lot of vacuum power, both the tank used and the pump should be large. Tanks larger than the normal ones used are going to be needed if both wet and dry methods of excavation are to be applied.
Vacuuming, either wet or dry, is considered safer than older digging methods, but still, safety measures must be adhered to. Proper training on how to handle and operate machines safely should be introduced. Special training for the people going to operate the machines should first take place before they start. Professional training of the workers who are going to work the machines should take place. Workers should be knowledgeable on how to avoid damaging underground utility pipes and power lines. Proper gear and clothing is a necessity for workers. These include hand gloves and dielectric boots.
Digging by using the vacuuming technique is a precise process. Sometimes things do not always go right in the excavation process. Human error or mistakes can make people to identify the excavation site wrongly. Mistakes of this kind may lead to explosions from gas leaks and electrocutions. It is vital that the necessary authorities are contacted to confirm if the intended digging location is the correct one, and provide accurate maps.
The vacuum trucks and the pumps that the drilling company uses to dig should be well maintained. This makes sure the machines perform according to their maximum ability. Though wear and tear is unavoidable in this situation, machines should often be monitored to be on the safe side. Regularly lubricate the machines, placing emphasis on the moving parts. Examine parts like hoses and nozzles. …
