Vacuum Excavation: Best Practices for Top Productivity
In digging, numerous ways of excavation are used. Some are older methods that are more traditional in nature while others are more 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. Hydro excavation uses water pressure that damages old pipes and electric wires that are brittle, thus dry excavation is deemed as the safer choice.
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. Therefore, the people going to use them must be taught how to operate them. Due to the presence of underground utility pipes and power lines, the operators of the machinery should be careful. Proper gear and clothing is a necessity for workers. Dielectric boots and hand gloves are examples.
Digging using the vacuuming method provides precision in the excavation process. Accidents can sometimes occur in the excavation process. This can be caused by mistakenly digging in the wrong site due to wrong identification process or human error. Gas explosions due to leaks, or even electrocutions can be brought about by interference from such mistakes. It is vital that the necessary authorities are contacted to confirm if the intended digging location is the correct one, and provide accurate maps.
Proper maintenance of the vacuum trucks and the pumps used by the drilling company must be observed. This will ensure that the machines will perform at expected standards. Considering that tear and wear is normal, the machines should occasionally be checked. Lubrication of the machines used, especially the moving parts should be regularly done. Parts like nozzles and hoses need regular examination. Following these best practices will help ensure efficient vacuum excavation.
