Visionscape uses a combination of high pressure water jetting and vacuum unit, bucket machine cleaning of pipes, and CCTV pipe inspections by means of a crawler or push rod camera system. In addition to Backhoe Excavators and Swamp Buggies, we also deploy the following equipment to execute the works with the quantity required being dependent on the exact scope of works.
DRAINAGE INDUSTRIAL VACUUM TRUCKS
The specification is usually for a combination of high pressure water jetting and high air flow vacuum machine for the cleaning of drains and its affiliated tasks. This is built operational friendly and easy to repair.
Our tanks are usually made out of 3CR 12 Stainless Steel or similar compliant materials. They are a bell type tank with the inner vacuum area having a waste capacity of about 7000/4000 litres and the outer shell having a capacity of about 8000/5000 litres of fresh water. The waste tanks are 4.5mm thick with 6mm ends and the outer fresh tank has a wall thickness of 3mm. Baffles are fitted in the water tanks and they not only prevent water surge, but also increase the strength of both tanks. The tanks are equipped with a drain valve to discharge all excess water quickly and efficiently.
HIGH PRESSURE VACUUM AND HYDRAULIC PUMP POWER SOURCE
The high pressure vacuums and pumps are driven from an automatic clutched PTO capable of delivering at least 20% more kilowatt than the systems attached to it is rated for at maximum continued operation. Either the water or vacuum system is able to engage and/or disengage at full revs without interference to either system. The hydraulic systems are also PTOO driven and operated independently. The control devise for these systems are usually mounted at the rear of the machine in the control panel.
HIGH PRESSURE PUMP
Our high pressure water pumps are capable of about 250 litres per minute at a constant pressure of about 120 bar with an input speed of either 1500 or 1800 RPM. They are always fitted as per manufacturers’ specifications in an easily accessible place with all relevant safety features i.e. regulator, secondary filtrations, tank returns, etc.
JETTING SYSTEM AND HOSE REEL
Clean water from the H.P. pump is fed to an easily accessible swivel (180 degrees) rear mounted hydraulically operated hose reel. The hose reel is fitted with a grease lubricated rotary joint and operated hydraulically in both directions. The speed of the hose reel is controlled via a constant torque bi-direction control valve and is capable of holding 180 meters of 25mm lightweight thermoplastic sewer hose.
In addition to Drainage Management, we also carry out Monitoring and Analysis Services which includes:
- Sewage/ Waste Water Effluent analysis
- Sludge analysis
- Drilling waste monitoring/analysis.
- Inorganic/organic analysis
- Hazardous substances analysis
- Ground water monitoring/analysis
- Rain water analysis
- Facility/equipment monitoring
