Level Sensing System for Tunnel Excavation TL-300
The TL-300 Series Level Sensing System for Smooth Excavation with Shield and Pipe Jacking Machines.
Cities have recently introduced more underground tunnels as a way to ease aboveground congestion. This has led to increased demand for sophisticated technology in the field of tunnel excavation. When connected to our TMG Series Attitude Sensing System, the TL-300 Level Sensing System continuously measures changes in the level of shield and pipe jacking machines during the excavation process.
This combination assures accurate control which is so vital to tunneling, especially along fragile natural slopes.
Features
- Easy hose coupling for pipe jacking
Quick coupling connectors, with connectors at both ends of the hose, allow easy connection and disconnection.
- Small and light weight
Designed compact for small diameter tunneling.
- Monitor unit warning function
Various errors such as level and communication errors are clearly displayed on the monitor.
- Automatic roll and pitch angle correction
By connecting unit to the Tokimec Tunnel Gyro, level deviations caused by rolling and pitching are automatically corrected for.
- Wide measurement range
300B :max. level 6250 mm
300BH :max. level 25300 mm
Pipe Jacking Gyro Navigation System PN-S1
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.
Features
- Absolute direction
Gyrocompass detects absolute direction.
Servo type acceleration meter measures pitch and roll.
- Real time machine position
Machine 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
