SLP System – Periphery Drive
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 an added remotely controlled periphery drive power booster container.
- Airlock kits available for pipe diameters of 78‑in 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 assist ground flow and cutting in cohesive soils.
- Variable‑flow slurry routing controls hydrostatic balance to the cutting head or plenum chamber based on ground conditions.
- Sealing system rated to 3 bar; 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 the Akkerman TGS guidance system.
