One of the biggest dangers of underground excavation is striking a utility. With the use of vacuum potholing, however, utilities can be located safely — free from disruption or damage.
This process can particularly locate natural gas pipelines, underground water pipelines, valve boxes and other underground utilities quickly and safely. It is typically used in excavating or trenching, to create a hole about two square feet and as deep as needed to expose the utility.
How Vacuum Excavation Works
It uses a vacuum potholing equipment that helps remove soil from a hole on land using a powerful suction, which then penetrates, expands and breaks up soil. It uses a 30-centimetre wide suction pipe; the speed of the suction inlet air may reach 220 mph or 100 metres per second.
The end of the pipe is typically smooth to reduce risk during the excavation process. Using a powerful water jet or a compressed air lance is part of the process to loosen the earth first. Other types of equipment such as an excavator use a heavy metal device to loosen the soil instead, which could only damage the underground utilities or infrastructure that is being located. It is safer than other methods of excavation, such as shovels and post hole borers.
Benifits of Vacuum Excavation
Vacuum excavation is one of the best practices for safely inspecting underground facilities, reducing more than half the chance of damaging the buried utilities in a site. When used with ground penetrating radar, this process can surely guarantee a safe working site.
Apart from damage and risks of accident, below are some of the other benefits of vacuum excavation:
- It prevents utility customer outages.
- It reduces down time for utility line repairs.
- It keeps your equipment working.
- It reduces disruptions of traffic and other surface activities.
- It can help reach areas difficult to access (the vacuum tube can be pulled to different lengths and depths for every excavation requirement).
