Vacuum Excavation: Best Practices for Top Productivity
In digging, numerous ways of excavation are used. 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. An example is the vacuum excavation method that uses either water or air in the 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. 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.
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. 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. In cases where both dry and wet excavation are to be done, then larger than usual tanks are going to be needed.
However much vacuuming, whether dry or wet, is considered to be safe than old fashioned digging methods, safety issues must be addressed. Proper training on how to handle and operate machines safely should be introduced. There are modern machines that require specialized training before they are used. Therefore, the people going to use them must be taught how to operate them. 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. These include hand gloves and dielectric boots.
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. By reaching out to the concerned authorities, it will help in ensuring you are digging at the correct site and you will also be given 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. 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. These practices will ensure efficient vacuum excavation.
