Data log system

The data obtained through the built in sensor of tunneling machine displays in real time and is saved and recorded in the memory card by the analyzer.

• Cutter torque, Hydraulic pressure,
• Position
  (Pitching, yawing, rolling, offset)
• Pressure
  (Charge, discharge, ground water)
• Jacking speed, temperature and error diagnosis

Optimum control machine position for curved pipe jacking

The north seeking gyrocompass is an absolute directional sensor that detects direction from the North Pole. This sensor has been used with extremely satisfactory results in curved pipe jacking systems.
Real time machine coordination and position can be determined by absolute direction and distance data. This systems allows drastic reduction in survey work.

• Absolute direction
  Gyrocompass detects absolute direction.
  Servo type acceleration meter measures pitch and roll.
• Real time machine position
  Mache position is determined in real time and maintained in accurate alignment by the gyrocompass and distance meter.
• The increase in efficiency of the work
  Reduction in amount of surveying which improves work efficiency.
• Graphical survey image
  Input of survey results executes transverse calculation and deviations relative to design tunnel alignment will be displayed.
• Easy-handling and user-friendly software.
  Graphic user interface navigate operator clearly.
• Data saving
  Various related values saved in database every 10cm.
