Since the recent past there have been tremendous improvements in the construction industry. For example, the traditional process of digging the earth, also called as excavation, is now taken over by machines. One such process extensively used in the excavation process is Hydro Excavation.
The process of excavation:
As the very name suggests, hydro excavation involves use of water in the process of excavation. This is a non-mechanical process because you do not find any drilling or JCB machines digging the earth. This is a process wherein soil is broken by means of pumping water at a very high speed through specially designed pumps and hose pipes.
Backfilling not required:
This process is regarded as non destructive digging because this process of excavation dislodges the soil only at the place where the water is pumped. This process will not cause any damages to the surrounding places. Thereby, this procedure will not involve the necessity of backfilling.
Mechanical excavation needs back filling:
On the contrary, in any mechanical digging process, there is every possibility of places surrounding the excavated area getting damaged. This will necessitate back filling which can be time-consuming and also involve additional expenditure.
Some of the other salient features of hydro excavation and their specific area of application and other related issues could be summarily explained as follows:
· When water is pumped, it dislodges the earth. The slurry so created is drained out through a vacuum tube which is attached to the hosepipe. Thereby human or mechanical intervention for removing the debris does not arise at all.
· During the process of vacuum excavation Melbourne technicians conduct, you may come across some of the existing facilities like the water pipes or telecommunication cables coming along the line of excavation. The exclusive day lighting utility available in this hydro process effectively highlights such impediments in the excavation process.
· Many of the civil contractors now make use of this excavation process for making post holes, slot trenching and such other tasks. This process of digging saves a considerable amount of time, and it is cost effective too.
· If the place where the excavation is to be made is congested or located in a busy place, then excavation can be carried by a remote digging process. In this process, the truck carrying hydro digging or excavation unit will be located at a convenient place. Only the hose pipe which is connected to the truck will be moved to the place where the excavation process is to take place.
· Some of the excavator trucks have a water tanker with a capacity of 800 gallons. Such trucks are equipped with FX 60 vacuum excavation pump. These types of excavators are capable of working under any hostile terrain.
· Some of the trucks are equipped with heaters. These enable the excavators to continue with the excavation process even under severe cold season.
· The excavation process is carried out by sufficiently trained and highly experienced personnel. The personnel involved in excavation tasks are appropriately insured.
Other services available:
Normally, in addition to hydro trenching or excavation, the agencies also undertake various other excavation tasks like chain trenching, directional drilling, vacuum excavation and such other tasks.
