Laying subterranean pipelines for gas, water or other vital utilities can be a time-consuming and complicated task at the best of times, and anything that can speed the process along is generally welcomed by pipeline contractors and services. One of the most time-consuming aspects of many pipe laying projects is excavating the ground that the pipes will be laid in, especially; to that end, many pipeline laying companies are ditching slow, traditional excavation methods in favour of vacuum excavators.
What is vacuum excavation?
Vacuum excavation is pretty self-explanatory, and exchanges the traditional diggers and excavation machines used in traditional excavation projects for a truck fitted with a powerful vacuum pump. This pump is connected to a long, flexible hose, which is used to suck soil, groundwater and other debris out of a trench or hole quickly and effectively, and the collected material is stored in a special bay on the vacuum truck until it can be emptied.
Depending on the vacuum excavation service you choose, the vacuum excavator used at your job site may also be fitted with extra features. Many vacuum nozzles come fitted with hard metal 'teeth' designed to assist with breaking hard ground, concrete and asphalt. Others have an attached, high-pressure water jet to break up stubborn clods of earth and small rocks; vacuum excavators that use these jets are often called hydro excavators.
What are the advantages of choosing vacuum excavation over traditional excavation for pipe laying projects?
Choosing vacuum excavation services to create pits and trenches for your pipes can have a number of benefits over choosing more conventional excavation services and methods:
Vacuum excavation can be significantly faster than conventional excavation methods, allowing you to get your pipes laid faster. It is particularly fast when compared to the work of a single small excavator so that vacuum excavation can be particularly useful for small job sites without a lot of space for extra machinery (such as sites on busy roads and thoroughfares).
Vacuum excavation is particularly well suited for pipe-laying purposes because it causes minimal disturbance to structures already places within your excavation zone. While the buckets and drills of conventional excavators can cause severe damage to existing pipework, vacuum excavation can confidently be used directly alongside existing pipes, so vacuum excavation is perfect for laying pipes in busy urban areas that already have a significant existing infrastructure.
Easy disposal of waste
Choosing vacuum excavation over traditional excavation also means you don't have to purchase or hire a separate vehicle to carry the soil and debris removed from your pipe pits and trenches. Instead, the removed matter is stored inside the excavator itself, saving space on smaller job sites and allowing the matter to be easily replaced once work is completed.
