Flat Jack Testing Accessories

Flat Jack Testing Accessories

The Sisgeo’s Flat Jack Testing Accessories are designed to complement flat jack systems for stress measurement in masonry, concrete, and rock structures. These accessories ensure accurate and reliable data collection in structural health monitoring, helping engineers assess load-bearing capacities, stress distribution, and deformation in existing structures.

Typically, the user should select bill of materials based on deployment scenario:

1. Flat Jack: A thin, flat hydraulic jack inserted into masonry or concrete to measure stress changes.
2. Hydraulic Pump: Generates hydraulic pressure to inflate the flat jack for stress testing.
3. Pressure Gauge: Measures the applied pressure during testing.
4. Data Logging Interface: This is the interface that allows the flat jack systems to connect with compatible data loggers for data collection and monitoring.

• MIND Portable Readout: A compact, multichannel readout unit for local readings of Sisgeo instruments.
• CRD-400 READOUT: CRD-400 is a new generation multipurpose readout designed to take readings of all instruments including vibrating wire.
• WR-Log Wireless Node: Wireless data transmission and remote monitoring through the node.
• OMNIAlog Datalogger: Centralized data collection for remote monitoring and analysis.

Applications of Flat Jack Testing Accessories:

Sisgeo’s Flat Jack Testing Accessories are designed for structural stress analysis in masonry, concrete, and rock formations. These accessories support precise and non-destructive testing in various engineering and geotechnical applications, including:

• Structural Stability Assessments – Evaluating in-situ stress in historical buildings, bridges, and large infrastructure.
• Tunnel and Rock Mass Monitoring – Measuring stress distribution in tunnel linings, rock formations, and underground structures.
• Retrofitting and Rehabilitation Projects – Assessing the structural integrity of aging or damaged structures before restoration.
• Concrete and Dam Inspections – Analyzing stress and strain in large-scale concrete structures to ensure safety.
• Load-Bearing Capacity Analysis – Determining the load resistance of masonry walls and concrete elements.
• Seismic and Settlement Studies – Monitoring stress variations due to seismic activity or foundation settlement.
