Robotec Auto Survey System

System Summary

The prism target are installed at multiple points in a shield machine, allowing Total Station (TS) to automatically survey these targets, which enabling calculation of TBM angle in contrast to the tunnel alignment on shield tunneling sites.

Main Specification

Improving Cycle time

This system can be used to improve cycle time by reducing the survey time and frequency due to automatic surveys.

For example)
Save working time
Save calculation time
Save examination time for direction report of next ring

Enhancing survey accuracy

Save human errors by reducing incorrect indications of next ring.

For example)
Target Deviation
Calculation of survey results
Excavation Indication

Proven performance in shield tunneling for large and medium tunnels

We gave numerous works mainly at shield tunnel construction sites of big and middle radius.

Effective from installation

・Precise survey results

・Prompt calculation of co-ordinate value

・Reduce correction survey frequency

・Durable shaky and hot environments

・Save static time (for example; power recovery)

・Enables Surveying vertically

・Saves working time when compared traditional work environments
