Industry Best Practices for Vacuum Excavation
In digging, numerous ways of excavation are used. Some are older methods that are more traditional in nature while others are more modern. On account of drilling companies using these new methods, digging has become easier, faster and safety is more assured than in the past. Vacuum excavation is an appropriate example which uses water or air in the digging process. By noting the following practices, you are assured of an efficient 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. On the other hand, where the soil is loose, sandy and with a lot of gravel, dry or air excavation is recommended. Hydro excavation uses water pressure that damages old pipes and electric wires that are brittle, thus dry excavation is deemed as the safer choice.
It’s important to take into account the size of the truck to be used in the excavation in relation to the size of the vacuuming pumps. 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. Where there is going to be excavation using both wet and dry methods of excavation, then you are going to need above average tanks.
While vacuuming- whether wet or dry- is generally a safer method than older traditional digging methods, proper safety considerations should be observed while digging. Before handling and operating the excavation machines, the workers should be taught safety procedures. Some modern machines cannot be put to work without the necessary specialized training of the potential users. Professional training of the workers who are going to work the machines should take place. Due to the presence of underground utility pipes and power lines, the operators of the machinery should be careful. 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. The wrong site can be excavated due to human error, or choosing the wrong site. Such mistakes can cause interference with electric lines and gas pipes leading to gas explosions or electrocution. 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 the machines will perform to desired expectation. Tear and wear often occurs to machines that are being used, so close monitoring should be paramount. Regular oiling of the machines, especially the moving parts is vital. Parts like nozzles and hoses need regular examination. Following these best practices will help ensure efficient vacuum excavation.
