Hydro Excavation is a non-destructive procedure that employs a combination of highly pressurized water and vacuum to simultaneously excavate and evacuate earth materials. The pressurized water is used to break and loosen rocks, soil, gravel and clay into slurry mixture. The slurry is simultaneously sucked up and conveyed into a debris tank for discarding. A suction excavator also known as vacuum excavator is used by excavation companies Melbourne has for the procedure.
Benefits of the procedure
Suction excavation is the most preferred method of excavating because of efficiency and precision. The accuracy of the method minimizes accidents and injuries to workers and other individuals and causes minimal disturbance to the surrounding areas.
Hydro Excavation is way safer than the conventional excavation using excavators. Excavator buckets often cut infrastructures such as gas and electrical lines resulting in grave injuries and even death. The hand held wand allows workers to carefully and safely get rid of soil from these lines without damaging them.
Because vacuum excavation limits damage to buried utilities, it eradicates the cost required for repair and restoration. Consequently, it minimizes the time spent on the job and minimizes inconveniences due to interference with underground systems. Suction evacuation is not destructive to the landscape and very little time is required to restore the land to its original condition.
Conventional methods used by Melbourne excavation companiesrequire hiring a number of heavy machinery to carry out the excavation. Hiring an excavator, truck and dump trucks necessary for conventional excavation raises cost of the project. The procedure will require hiring of one piece of equipment to handle the same task. As a result, the cost of the project is minimized significantly.
The equipment can be effectively handled by fewer workers compared to traditional procedures that require a crew of operators and drivers. This makes the procedure cost effective.
Applications of Hydro Excavation
Vacuum excavation is applied in Potholing to expose underground utilities. Since the suction excavation is non-destructive procedure, it allows underground infrastructure to be exposed without damaging them. Potholing is also time-saving and an economical method applied byexcavation companies in installations of underground lines, locating buried utilities and allows new installations to be carried out without damage to already existing utilities.
The precision of suction excavation enables the method to be used to remove debris and clean various structures without destruction to the surrounding areas. The method is effective for vacuuming up spills and sludge removal. The method is applied rehabilitation of pipes and sewer lines. The method minimizes damages to pipes.
Vacuum excavation can be used in slot trenching where narrow channels are made for the purpose of laying cables, pipes and other underground utilities. The method is effective and non-destructive and can be utilized even on frozen surfaces.
The precision of vacuuming makes it an ideal method of piling hole excavations. Previously installed utilities are unharmed during excavation compared to the risk posed by conventional methods.
Suction trucks are usually equipped with truck-mounted heaters, a phenomenon that allows them to be utilized even during cold weather. Traditional methods employ the use of wood and coal to thaw frozen surfaces. Consequently, suction method is friendly and safe to the environment. Visit http://envirolink.com.au/.
