Automated Bentonite Injection System
The Akkerman Bentonite Injection System (ABIS) delivers precision bentonite injection at optimal tunnel intervals to reduce jacking forces and facilitate efficient and extended length pipe jacking using touch screen functionality from the system monitor.
ABIS system is comprised of a Control Skid housing with flow meter and Monitor Touch Screen. The ABIS system connects to 10 Remote Station Control Boxes, each with three linked Automated Injection Ball Valve Assemblies for point flow distribution onto the pipe annulus and at the Intermediate Jacking Stations.
FEATURES:
- ABIS package provides totalized flow control at each valve location using touch‑screen functionality from the system monitor.
- Monitor touch screen controls valve injection volume and displays valve flow, pressure, injection sequence, IJS extend/retract, and tunnel lighting.
- Standard configuration includes components for a 2,000‑ft tunnel with flexibility for varied project conditions.
- ABIS system keeps operators safely out of the tunnel interior.
- Logs cumulative dates and times, station valve injection, totalized volume and pressures, and IJS pressure and displacement data.

Testimonials
Our interaction with Akkerman began on a project where we were struggling with their competition’s machine. Changing machines during a project to their machine required a leap of faith on our part. That project completed 20 years ago turned out to be successful and propelled us into 20 years of completing scores of successful micro tunnel projects throughout North America. Providing many innovations throughout this time has allowed us to mine many geology types and increase drive distances with curves to over 2500 lf. I can attest 30 years ago, technology did not exist that today allows us to complete projects efficiently and at a lower cost. Their leadership in providing technically superior AMERICAN made equipment is second to none in the world today.
