Equipment

Akkerman Inc.

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

In recent years we have acquired different spare parts for our Akkerman brand TBMs, which have allowed us to have the equipment ready. We have used our tunnel boring machines in 2 emergency projects recently:

  • Completion of the construction of the El Valle Collector, with reinforced concrete pipe of 2.13 meters inside diameter for the municipality of Tlajomullo de Zuniga Jalisco.
  • Construction of the Jamapa Collector in the municipality of Ecatepec de Morelos (New construction). With 1.22m RCP pipe.
