APPLICATIONS:
- Detection of deformation modulus and elastic modulus of the rock mass in borehole
- Acquisition of rock parameters and guidance for the classification of rock mass
- Guidance for bedrock grouting treatment procedures and optimizing construction design
INTRODUCTIONS:
Static elastic modulus is a very important parameter of rock mass in the construction of large-scale projects such as water conservancy and hydropower engineering. The measurement of HX-JTM-02B digital borehole static elastic modulus tester is based on the bearing plate method which is one of the situ test means. The equipped jack, oil pump and tubing are exported products. With the use of high-precision displacement sensor, this tester is characterized by its accurate data, good stability, safety and reliability, light weight and small size.
FEATURES:
- The probe is provided with video observation equipment, showing borehole and lithological conditions in real time so as to ensure the safety of equipment in borehole.
- An electronic compass is optional for the probe to determine the orientation of testing point.
- Provided with low-power digital host control box and built-in battery allowing to work continuously for 6~8 hours.
- Visual Windows interface, real-time data observation and acquisition, automatic data storage, convenient operation and high detection efficiency.
- The pressure curve and displacement curve of the bearing pressure plate at the measuring point can be viewed in real time.
- Provided with imported oil pump and sensors with a displacement accuracy of 0.001mm.
- High-precision data acquisition with a conversion accuracy of 13-bit.
- The analysis software has a friendly interface. Elastic modulus can be calculated automatically after setting the parameters. Data can be automatically exported to Excel which is easy for the engineering staff to edit and process.
- This tester is light in weight and convenient for operation and transportation.
- Excellent after-sales service and technical support. On-site training is available.
