Vacuum Excavation: Best Practices for Top Productivity

In the process of digging, there are a lot of techniques in use today. Though most of the methods used today are modern, others are traditional. The process of digging has improved in ease of digging, speed and safety due to the fact that drilling companies are using these new methods. An example is the vacuum excavation method that uses either water or air in the process. Here are some tips and practices for efficient vacuum excavation.

There are some soils that are hard-packed and heavy, where air cannot penetrate well. In such cases, hydro excavation, or the use of water is most preferred. On the other hand, where the soil is loose, sandy and with a lot of gravel, dry or air excavation is recommended. 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. When the size of the pump in use matches the size of the water or air tanks, then the desired vacuum power will be realized. This means that if a lot of vacuum power is needed, then both the tank for holding air or water and the pump should be equally 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. All their operators must be shown how to use them safely. 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 by using the vacuuming technique is a precise 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 that the drilling company uses to dig should be well maintained. This will ensure the machines will perform to desired expectation. Though wear and tear is unavoidable in this situation, machines should often be monitored to be on the safe side. Regular oiling of the machines, especially the moving parts is vital. Examine parts like hoses and nozzles. Following these best practices will help ensure efficient vacuum excavation.
