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. These new methods used by drilling companies have made digging easier, faster and safer. 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.
There are some soils that are hard-packed and heavy, where air cannot penetrate well. 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. In terms of safety, dry excavation is the better method, unlike using pressurized water in hydro excavation, because you cannot damage older pipes or electrical wires that are brittle.
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. Tanks larger than the normal ones used are going to be needed if both wet and dry methods of excavation are to be applied.
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. Special training for the people going to operate the machines should first take place before they start. All their operators must be shown how to use them safely. There are utility pipes and power lines underground, and so workers should be conversant on how to work around them. Proper clothing and gear to be used should be given to the workers. 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. 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 used by the drilling company must be maintained well. This will ensure that the machines will perform at expected standards. Though wear and tear is unavoidable in this situation, machines should often be monitored to be on the safe side. Lubrication of the machines used, especially the moving parts should be regularly done. Parts like nozzles and hoses need regular examination. These practices will ensure efficient vacuum excavation.
