Tunnel Seismic Prediction

The all-in-one solution combines the proven method with cutting edge technology

TSP 603 wireless is a next-generation technology that succeeds the world’s most successful family of Tunnel Seismic Prediction systems. It combines the advantages of its predecessors with the most advanced technology bringing you one step closer to digital transformation in underground construction.

These are the highlights:

• Light weight “Ready-to-use” system
• Wireless connection to all components
• Highly accurate synchronization (< 20 μs)
• Autonomous Wi-Fi network
• Simple installation within 30 min
• Easy to operate by site personnel
• Applicable in Drill & Blast and TBM
• Measurement time
  • < 60 min. @ single shot recording
  • < 15 min. @ multiple shot recording
• Best suitable for TBM integration
• Optional with impact hammer source
• Specially designed for periodic and continuous data acquisition

TSP Impact is a powerful mechanical Impact Source for fast and continuous seismic Data Acquisition and the ultimate expansion to TSP 603 wireless. With the combination of both technical achievements, your TBM tunnelling becomes even more efficient and safer. 

How does TSP Impact work in your TBM?

• The pneumatic impact hammer is preferably mounted to a console behind the cutter head.
• It requires the TBM’s supply of compressed air (7 bar) and power.
• After each stroke when the TBM is at a standstill, it autonomously stretches radially against the rock through an opening in the shield.
• Immediately, striking of 5-10 shots starts and lasts only 1-2 minutes.
• The hammer is completely controlled via the control box or wirelessly via the tablet.
• The hammer’s procedure of Stretch-Shot-Relax is carried out after each stroke and at a different station.
• With the data of min. 20 shot positions, an analysis and geological forecast is made.
