Ø Detection of the deviation of effective prestress;
Ø Detection of the unevenness in the same bundle;
Ø Detection of the unevenness in the same section;
Ø Detection of the effective prestress of a single cable and the whole bundle of anchor cables.
Compliant specifications:
Technical Specification for Highway, Bridge and Culvert Construction ?JTG/T F50-2011?
Specification for Inspection and Acceptance of Construction Quality of Prestress and Cable Tension of Bridge (CQJTG/T F81-2009)
Technical Features?
1. Integrated tensioning method.is used to detect the effective stress of a single steel strand and the whole bundle of steel strands.
2. High level of safety. Set with the tensioning target, and tensioning warning value. Automatic presure application and judgement of curve inflection points.
3. Highly automated: stops immediately when the inflection point of the effective prestress value occurs, and counts immediately when the preset alarming values are set.
4. Guided operation process: Intelligently guides the operation, ensuring easier and simpler operation.
5. Highly efficient industrial-grade intelligent control system that features stable operation, clear boundary and flexible control.
6. High precision in displacement of the whole bundle, ensuring easy installation.
7. High compatibility. A on-site jack oil pump can be selected for testing.
8. Capability to calculate the unevenness of the force value in the same bundle and the same section. Avoids the test error caused by the uneven frictional resistance and the different heights of the exposed parts of clips.
9. Capability to detect the effective prestress of a single cable and the whole bundle, and it can make up the tension.
10. Prevents manual tensioning and errors in inflection point judging. Records the force and displacement curve for post-analysis and tracing.
11. Supports data uploading and data viewing through a cloud platform.
