Monitoring Objective
Excavation changes soil stress and loading on retaining structures. Monitor horizontal displacement at depth and add tilt or crack points on supports and nearby structures.
Monitoring Parameters
- Deep horizontal movement of retaining walls and soil
- Tilt of braces, columns or adjacent buildings
- Surface cracking and settlement
- Construction-stage trends and thresholds
Typical Configuration
The RT-1015 provides a lightweight, field-assembled borehole array. RT-1020 sensors instrument selected depths on an RS485 bus. The RT-1070 adds rapid wireless tilt points on supports or nearby buildings.
Deployment Considerations
Establish borehole baselines before excavation and keep sampling consistent across construction stages. Protect wireless brackets from loosening and construction impact that could create false movement.
FAQ
When should I choose the RT-1015 rather than RT-1020?
Choose the RT-1015 for continuous field assembly, low handling weight and rapid deployment. Choose RT-1020 sensors for fixed-depth points connected on an RS485 bus.
