Akkerman Bentonite Injection System - Reduce Jacking Forces on Pipe Jacking and Tunneling Projects

Our newest lubrication solution for pipe jacking and microtunneling operations, the Akkerman Bentonite Injection System (ABIS) delivers automated bentonite injection at optimal tunnel intervals to reduce jacking forces and facilitate efficient and extended length pipe jacking. The ABIS package delivers totalized flow control at each valve location using touch screen functionality from the main system monitor. This ABIS system comprises a Control Skid housing the flow meter and Monitor Touch Screen. It connects up to 10 Remote Station Control Boxes, each with three linked Automated Injection Ball Valve Assemblies for point flow distribution onto the pipe annulus. The Remote Station Control Boxes are also capable of controlling and monitoring Intermediate Jacking Stations (IJSs) functions. The standard ABIS configuration equips microtunneling and pipe jacking contractors with components for a 2,000-linear foot tunnel, and the flexibility to suit a variety of project conditions. The distance between Remote Station Control Boxes and Automated Injection Ball Valve Assemblies is determined by the contractor and individual project requirements. The ABIS system’s hub is its innovative yet simple 10.4-inch (264mm) Monitor Touch Screen interface. The user’s interaction from the menu screen on is intuitive and straightforward. With totalized injection control, everything from valve injection volume, current valve flow volume, pressure and injection sequence to IJS extend and retract, and tunneling lighting are all commanded from the above ground Monitor Touch Screen. The monitor’s resistive touch screen feature makes it possible for operators to initiate commands without removing safety gloves. The ABIS system logs cumulative data on dates and times, station valve injection totalized volume and pressures, as well as IJS data including pressure and displacement. If bentonite injection control is preferred from the microtunneling control console, the Monitor Touch Screen interface can be transferred via Ethernet cable to the control console for MTBM operator command. The Monitor Touch Screen is powered by single-phase 120VAC power. Like all Akkerman equipment, the Control Skid is designed with conveniences for a project environment in mind. The Monitor Touch Screen and bentonite control plumbing mount to the Control Skid for ease in transport and site set-up. The flow meter, pressure transducer, in and out manifold, and un-loader and relief valves are easily accessible to connect to the bentonite supply lines. Affixed hose and cord hooks on either side of the skid promote project tidiness. The skid is easily transportable using the fork pockets and a lift eye. The ABIS system safely removes operators from the interior of the tunnel; however, its safety features do not end there. If the operator must enter the tunnel, each Remote Station Control Box contains an integrated, flush-mounted 24 volt LED light as well as a detachable, magnetic light with a 30-foot (9.1m) cord to illuminate the tunnel and the Automated Injection Ball Valve Assembly sites. Lighting is managed from the Monitor Touch Screen. The ABIS system pairs with all Akkerman lubrication solutions as well as other manufacturer’s bentonite and lubrication pumps.
