  • Description

RSM-DCT (W) Borehole TV Tester

Model: RSM-DCT(W)


Application

It is suitable for such engineering fields as engineering geology, hydrological geology, geotechnical engineering inspection and monitoring. It is suitable for various boreholes including vertical borehole, horizontal borehole, anchor cable (rod) borehole, geological borehole and concrete borehole. It can form digital borehole core sample for permanent preservation, especially suitable for the crushing zone strata where actual core samples cannot be obtained. The specific classification is as follows:
For concrete: Conduct pile foundation boring for coring verification, observe the location and extent of cavity, cracks, segregation and other defects in concrete;

 

For the pipe pile: Observe the pile to see if there are anomalies or defects in it, and directly check the joints, quantitatively analyze pile quality: broken area, fracture and crack location, length, width, direction and so on;

 

For engineering and hydrological geology: Observe the characteristics and subtle tectonics of geological bodies in the borehole, such as stratigraphic lithology, rock structure, fault, cracks, sandwich, karst, and draw geological histogram;

 

For underground pipes: Observe the contents of pipeline, quantitatively analyze pipeline quality: broken area, location and length, width and direction of fracture and crack.


Features

1. Intelligence:

Obtain images in a wireless way, control RSM-DCT (W) borehole tester to capture images and videos through the notebook or tablet computer, perfectly solve the problem that field observation is affected by high light and environment using the high resolution display, high brightness and other characteristics of tablet computer; meanwhile, solve the problem that field image is inconsistent with the analyzed image by directly judging the results at the field;

 

2. Reliability

With stainless steel shell and tempered optical glass probe cover, the probe can withstand the maximum pressure of 10MPa;

 

3. Portability:

Host size is 260 × 220 × 120mm and its weight is 2.5kg, and the maximum weight of the probe is less than 5kg;

 

4. High-definition:

Color 720 wire with low illumination is used for camera, with 0.01Lux illumination and 1.3 million pixel;  the resolution of crack is up to 0.1mm; the intensity of light source can be continuously adjusted, to ensure that various detection objects can be clearly imaged;

 

5. High precision:

Image depth resolution is 0.1mm, and angle resolution is 0.1 °;

 

6. High efficiency:

The fastest detection speed is up to 6m / min; the whole system is simple to connect and easy to operate, and conventional Windows system operation is easy, convenient and efficient to use;

 

7. Wide viewing angle:

The viewing angle of camera is wide, with the elevation angle of 38°, depression angle of 17° and horizontal angle of 360°, and thus panoramic imaging can be realized, without the need for focusing;

 

8. Low power requirements:

The host is powered by built-in high-energy battery and can continuously work for more than 15 hours; in addition, the host can supply power to the tablet computer, without the need for 220V AC power.

Software

1、The software can collect and save the images simultaneously at the field, and splice the images synchronously after the completion of collection;

2、It is easy to browse, the image can browse the histograms and plane development drawings at any direction, proportion and hole section, and virtualize the whole borehole or part of sample drawings;

3、The images and results are displayed in the mode of “What You See is What You Get”, and the display is fully consistent with the printing results;

4、Flexible switching between displays: It can display plane development drawings and 5、three-dimensional histograms. Three-dimensional histograms can be continuously rotated in 360 degrees;

5、Direct description of the core: The core can be directly described in the development drawings, crack tendency, inclination and width can be automatically extracted, the width accuracy is up to  0.1mm, and the azimuth accuracy is up to 0.1 °;

6、Flexible and beautiful printing output: Image printing output length, image layout mode and printing graph sections can be set and selected freely, thus realizing flexible and beautiful effect.
