Equipment

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.
