 Application

Ø High strain bearing capacity detection of pile

Ø Low strain pile integrity detection by reflected wave method (optional)

Applicable standards

Ø Standard Test Method for High Strain Dynamic Testing of Deep Foundations ASTM D4945-12

Ø Technical Code for Detection of Building Foundation Pile JGJ 106-2014

Ø Nondestructive Detection Code for Railway Engineering Foundation Pile TB 10218-2008

Principle

Working Principle:

RSM-PDT(B) tester will provide prediction on the pile bearing capacity, pile integrity, driving stresses and hammer performance for a given pile penetration. It is a relative low cost type of pile testing compared to static load test (MLT or CRP). The testing technique is quick and accurate.

 

RSM-PDT(B) tester also can be used to perform high strain pile bearing monitoring (HSPBM-Monitoring) to evaluate pile driving information for pile bearing capacity, pile integrity, driving stresses and transferred energy against pile penetration. The results are essential for the actual pile driving process and to obtain valuable data on the hammer, pile & soil system for re-design on the piled foundation (if necessary). 

 

Technical Features

1. Original instantaneous floating point amplification technology can take into account the distortionless acquisition of strong and weak signals;

2. Removable lithium battery is provided, desktop charger is supported and spare battery can be provided to ensure that the field work will not be interrupted;

3. The bilingual operation in both Chinese and English is supported;

4. The balance of strain bridge can be adjusted automatically to reduce the impacts of initial deformation of strain ring on signal acquisition and eliminate the signal zero drift;

5. The three-dimensional correction function for shallow defect is owned and the defect can be located accurately;

6. Built-in Bluetooth and WIFI can realize the function of real-time monitoring of wireless uploading;

7. With fast signal acquisition pace, the 60 hammers/min signal acquisition can be completed and the piling monitoring testing can be carried out in real time;

8. 8.4-inch true-color LCD screen is used, the curve is clear and intuitive and the backlight can be adjusted;

9. Portable high-strength engineering plastic shell with small volume and light weight can make operation easy;

10. 24-bit A/D combination design has large dynamic range and high signal to noise ratio;

11. Self-test for sensor installation status can be conducted in the field in real time;

12. Touch screen operation, friendly software interface and easy operation;

13. Analysis results by Case method, F-ZV curves and upper and lower traveling wave curves are displayed in the field;

14. With adjustable screen brightness, it can be used in a variety of lighting conditions;

15. Background color and curve color can be adjusted to meet customer needs.
