Akkerman periphery drive slurry microtunneling systems (SLP) are designed to deliver powerful performance for extended distances and curved alignments. These units include an on-board power pack with remotely selectable torque ranges to conquer changing ground conditions. Like all Akkerman microtunneling systems, the SLP lineup is fully remote-controlled from the surface and offers face access for cutterhead inspection, tool replacement, or obstruction removal.
Features:
- All SLP series microtunneling systems use the same Akkerman Microtunnel Control Container (MCC) as SLC models with the addition of a remotely controlled periphery drive power booster container.
- Airlock kits available for pipe diameters of 78in ID and larger per PVHO and OSHA standards.
- Sizing kits available to accommodate multiple diameters with one MTBM.
- Interchangeable cutterhead types: Soft Ground, Mixed Face, Rock
- Selectable high pressure jetting nozzles to assist ground flow and cutting in cohesive soils.
- Variable flow slurry routing to control hydrostatic balance to cutting head or plenum chamber based on encounter ground conditions.
- Sealing system to 3 bar capacity. Underwater retrieval compatible with sealed adapters.
- Mechanical and hydrostatic balancing with remote monitoring.
- Active MTBM monitoring and report generation including gas detection, roll, slurry monitoring, steering position, guidance, electrical connectivity, and more.
- All SLP systems compatible with Akkerman TGS guidance system.

Testimonials
I have used TBM equipment since 1996 for the installing pipes from 1.22 m to 2.44 m of internal diameter, they are very efficient in clays and silts with a high content of humidity.
I have also used GBM systems for driving smaller diameters in soils soft from the Valley of Mexico and are suitable for these conditions.
