5 Best Practices for Efficient 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. These new methods used by drilling companies have made digging easier, faster and safer. Vacuum excavation is one such method, where it is either done with air or water. The following tips and practices are helpful in ensuring successful excavation.
Some soils are usually hard-packed and heavy, and in such cases, air cannot be used efficiently in vacuuming. In situations like that, the use of water, or hydro excavation is the best alternative. There are areas where the dig site might have loose soil, with a lot of sand and gravel, and in such places, dry or air excavation would be a wise choice. 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.
With regard to the size of the vacuuming pumps to be used, it is important to take into account the sizes of the trucks to be used in the excavation. If the vacuum power created for the digging is to be strong enough, then the size of the air or water tank must correspond to the size of the vacuum pump. If the intended outcome is massive vacuum power, then it is required that the tanks for holding air or water, and the pump be big enough. Where there is going to be excavation using both wet and dry methods of excavation, then you are going to need above average tanks.
However much vacuuming, whether dry or wet, is considered to be safe than old fashioned digging methods, safety issues must be addressed. Training on safety measures while handling machines should be put into place. There are modern machines that require specialized training before they are used. All their operators must be shown how to use them safely. Workers should be knowledgeable on how to avoid damaging underground utility pipes and power lines. Workers should be given appropriate gear and attire. Dielectric boots and hand gloves are examples.
Digging using the vacuuming method provides precision in the excavation process. Sometimes things do not always go right in the excavation process. This can be caused by mistakenly digging in the wrong site due to wrong identification process or human error. Such mistakes can cause interference with electric lines and gas pipes leading to gas explosions or electrocution. For this reason, it is vital to contact the relevant authorities and confirm that the intended digging site is the right one, and get the necessary maps.
The vacuum trucks and the pumps that the drilling company uses to dig should be well maintained. This will ensure that the machines will perform at expected standards. Tear and wear often occurs to machines that are being used, so close monitoring should be paramount. Lubrication of the machines used, especially the moving parts should be regularly done. Examine parts like hoses and nozzles. Following these best practices will help ensure efficient vacuum excavation.
