Trenchless Underground Engineering
Gambit's thrustboring services offer trenchless solutions for installing underground pipelines and infrastructure without disturbing surface activities, existing structures, or traffic flow above.
Horizontal Directional Drilling (HDD)
HDD uses a drill bit and a positive displacement mud motor (controlled mechanically and hydraulically from a drill rig) to drill through soils and rock. Drill fluid is pumped through the pipe to a mud motor that converts hydraulic energy into rotary motion, spinning the bit. Sensors track bit location with data transmitted via hardwired electrical or electromagnetic signals.
Pipejacking
A trenchless technology for installing prefabricated pipe underground from a drive shaft to a reception shaft. Hydraulic jacks propel the pipe through the ground, transmitting force through the pipe to the excavation face. Spoil is removed manually or mechanically from inside the pipe during operation, allowing precise installation under roads, railways, and built-up areas.
Microtunneling
Microtunneling installs underground pipes by jacking pipe behind a remotely-controlled, steerable microtunneling boring machine (MTBM). The MTBM ensures excavated soil is fully controlled during advancement, providing precise grade and alignment control. Suitable for installing gravity sewer, drainage, and utility pipelines with high accuracy.
