ULTRASONIC DRILLING MONITOR KODEN DM-604R

- The equipment has been appraised and fully meets the standards 22TCN-257-2000 on construction and acceptance of bored piles/barette piles.

- Ultrasonic sensor system, the device can give fast results (20m/min) and is accurate to 98%, so it doesn't affect the construction time much.

- The device measures the actual diameter, shape, inclination, eccentricity of the borehole in 4 directions thanks to the ultrasonic sensor. Therefore, it helps the construction and monitoring unit to have a more intuitive view of the borehole to make a test report. As a result, the construction and supervision unit has a basis to easily make assessment, conclusions, handling plans and timely remedy.

- The device automatically detects and measures the shape of the bottom of the hole to help assess the level of dirt remaining in the hole, the opening of the drill blade when expanding the bottom.

- The device installs the sensor position (up or down) at any depth to help the construction and monitoring unit more clearly observe the location to be carefully checked.

- The system can measure the maximum bore diameter up to 8m and at a maximum depth of 100m, thus meeting most of the current constructions in Vietnam.

- Measurement method: using ultrasonic waves.

- Recording paper: electromagnetic induction type (DMP-250 A3-560).

- Transmit frequency: 100 kHz.

- Output power: 5W.

- Accuracy: 2% of the whole measurement.
