The objectives of the Ultra Sonic Pile Integrity Testing (RSM-SY7) are to determine the homogeneity and integrity of concrete between the probes. The data are used to confirm adequate concrete quality or identify zones of poor quality (due to inadequate vibration, segregation due to over vibration and/or improper concrete placement, washouts of cement due to groundwater flow, cracks due to shrinkage, contamination of the concrete, etc). If defects are detected, then further investigations should be made by excavation or coring the concrete as appropriate, or by other testing methods.

Features of the Gravity Ultrasonic Pile Integrity Test Drilling Monitor:

1. International first four-channel self-transmitting and self-receiving pile profile full-combination ultrasonic detection is provided and a number of invention patent authorizations have been obtained;

2. Self-transmitting and self-receiving circuit design is provided and there is no need to replace the location of acoustic pipe corresponding to probe; the fully combined testing of four pipes and six profiles can be completed in a single lifting, the detection speed is improved significantly and the working strength of detection personnel at the field is greatly reduced;

3. The controllable adjustment gain of test waveform of each profile is delayed;

4. The location of the first wave can be searched automatically and the magnification can be adjusted automatically;

5. The 12.1-inch super-large true-color LCD screen is adopted, the test waveforms, wave trains, wave speeds, amplitudes and other information of 6 profiles can be clearly observed in the field at the same time and the whole pile quality in the testing process can be clear at a glance;

6. The shifting distance of testing point is adjustable within 1-1250px without leakage point and need of repeated testing;

7. The automatic counting and lifting device can be connected conveniently and quickly and the maximum lifting speed can reach 60 m/min;

8. Using the high-strength engineering plastic shell, the instrument is beautiful and durable with solid structure;

9. Imported connectors are used and the complete machine is equipped with waterproof design.
