It is important to consider safety procedures and best practices when using Hydrovac equipment, regardless of the project. The equipment should be used with best practices for infrastructure projects so that it is safe for excavation, removal of utility debris, trench excavation, backfilling and restoration.
Hydrovac equipment can be used to excavate parts of roads and motorways that need to be repaved. Crews who have to dig trenches to get to grass or soil components can rely on hydraulic excavations to get the job done without disturbing the nearby surface. Using trench excavation, a HydroVac truck can easily locate and install supply lines and dig precise holes of varying depths and sizes.
One of the biggest advantages of choosing hydroexcavation over other excavation methods is its ability to promote a safer working environment. Hydro excavators offer a cost-effective and safe alternative to conventional excavators to locate and uncover underground utilities for repair and maintenance. It also speeds up project turnaround times and saves money in the long run by eliminating the time needed to clear piles of dirt and rust and repair damage caused by enormous industrial machinery.
Water extraction reduces the challenges of excavating buried utilities, pipelines and other underground infrastructure by using high-pressure water and a powerful vacuum to remove soil cover. Hydro excavators are equipped with a single flexible hose that delivers pressurized water to break the ground and state of the art vacuum technology to remove displaced soil and water from the excavation site. For winter work, hydro excavators can be equipped with heaters that release hot water pressure enough to dig through frozen soil, eliminating the harmful fumes and fire hazards associated with the thawing method required to prepare soil for excavation.
Hydrodigging means using pressurised water to uncover underground infrastructure such as sewer pipes. The soil is then softened and broken up with a large vacuum that sucks mud and debris from the tank of a hydraulic excavator. You can also use hydraulic excavation on different types of soil such as clay and sand.
Fresh water and soil excavation are included in one truck unit. Wet or muddy excavated material is sucked into a tank truck with a hydraulic excavator and transported to a landfill site.
Hydroexcavation, also known as hydrovac, or soft trench, is an ingenious process whereby a trench or hole is excavated using a pressurised heated stream of water to break open the ground. Unlike the water method of hydraulic trenching, high pressure water is used to loosen the soil before digging the borehole, allowing faster and more precise excavations that require less backfilling, less labour and less environmental impact than conventional drilling methods. Hydroexcavation is a safe method of excavation that can be used to provide utility customers with sensitive assets and unknown obstacles.
Due to the prescribed method of opening the ground to locate obstacles, the excavation of hydropower is preferred in many areas. Pipes and ducts are often buried in areas that should be dug, so a more modern approach is needed.
Hydro excavating works by injecting water through a hose into the soil to liquefy the soil. A vacuum system is then used to remove the watery soil and dig a trench or underground cavity. With Hydrovac, the excavation process is non-destructive and the excavation process consists of injecting pressurised water through a vacuum system to excavate the ground and leave the trench open.
