Mini Microtunneling & Auger Boring
Comprehensive trenchless solutions from precision optical-guided mini-tunneling to heavy-duty auger boring for all pipeline installation needs
Comprehensive Trenchless Solutions
Mini Microtunneling (Optical Beam)
Advanced optical beam guidance technology enabling infrastructure installation without open trench excavation. Using Guided Boring Machine (GBM) technology with optical beam guidance, we achieve maximum precision of ±0.01%. This method handles pipe diameters from 160mm to 1,000mm with continuous drilling up to 120 meters (extendable with additional launch pits).
The compact, quiet operation works in all soil types except rock, making it ideal for urban areas and sensitive environments. Extremely quiet operation enables work in populated areas without disruption, while the shallow depth capability prevents damage to existing infrastructure.
Auger Boring Technology
Auger boring is a trenchless pipeline installation method that uses a rotating cutting head and auger flights to excavate soil while simultaneously installing a steel casing or carrier pipe. The process involves jacking pipes horizontally through the ground from a launch shaft to a reception shaft, with the excavated material transported back through the pipe via continuous auger rotation.
This proven technology provides precise grade control essential for gravity pipelines, making it ideal for sewer installations, utility crossings, and projects where settlement must be minimized. With thrust forces ranging from 98 kN to 3,142 kN and pipe installation capabilities from 121mm to 1,720mm diameter, auger boring delivers accurate, efficient installations in virtually any ground condition.

Auger Boring Methods
Three distinct methodologies for different project requirements and ground conditions
Unguided Auger Boring
Traditional method where steel pipe is pushed forward using an auger boring rig while drilled material is extracted via drill head and auger. Direction and tilt determined during initial rig alignment.
Best for short to medium distances with stable soil conditions
Guided Auger Boring
Advanced pilot tube method using optical-electronic navigation with digital camera and GPS. Directional changes via steering head control surfaces using foundation soil reaction force.
Precision guidance for gravity pipelines requiring exact grades
Pilot Pipe Jacking
Advanced microtunnelling combining pilot tube jacking with powered reaming heads (PUD) or cutting heads (PPS). Connected to casing pipes with internal auger for maximum efficiency.
