These accumulation bodies have broken structures and loose materials. Under the action of rainfall infiltration, slope erosion occurs, the toe of the slope is wetted, and then instability failure occurs, resulting in secondary disaster events. To eliminate the threat of disasters to the lives and property of local people, borehole imaging technology is an important means in engineering investigation.

[0003] At present, the existing borehole imaging technology mainly targets intact rock and soil, with good observation hole effects and thorough cleaning inside the holes. The landslide and debris flow accumulation bodies have broken structures, and deep layers are often accompanied by mixtures of sediment and stones. When the existing borehole imaging technology is applied to landslide and debris flow accumulation bodies, a series of problems such as lens damage and unclear imaging are likely to occur. For the detection of deep geotechnical characteristics of landslides and debris flows, it still relies on traditional borehole sampling and laboratory analysis. This method has problems such as low efficiency, high cost, and difficulty in obtaining data in real time. In addition, existing equipment is difficult to be stable in the undulating accumulation bodies, the probe is prone to shaking, which easily causes poor imaging effects of the imaging probe, and the manpower to insert the probe into the detection hole leads to insufficient detection accuracy and sometimes accidental contact with the ground, damaging the probe. Therefore, there is an urgent need for an apparatus and a method that can work stably in the complex terrain of landslide and debris flow accumulation bodies and obtain deep geotechnical characteristics in real time.

A support tray 2 is fixed at the top of the triangular support 1. A lifting controller 5 is fixed at the top of the support tray 2. An exploration pipe 7 is coaxially installed at the upper and lower parts of the lifting controller 5. The cable 11 passes through the interior of the exploration pipe 7. The cable 11 cooperates with the lifting controller 5 and is used to display the elongation length of the cable 11. The end of the cable 11 is connected to a probe 10 for camera detection of the borehole. The lifting controller 5 and the probe 10 are connected to the main control unit 6. By adopting the above device, it can work stably in the complex terrain of landslide and debris flow deposits and obtain the deep geotechnical characteristics in real time, thereby well meeting the requirements of obtaining deep, high-precision and real-time stability borehole imaging under complex terrain and solving the problem of insufficient deep geotechnical detection ability in the prior art. During the specific use process, the entire device is carried on the landslide and debris flow deposits. The cable 11 and the probe 10 are lowered through the lifting controller 5 and penetrate into the borehole. The image inside the borehole is obtained through the probe 10. The main control unit 6 can analyze the data transmitted back by the image sensor 20, and the analysis result is displayed on the display screen 9 on the main control unit 6.

[0030] Furthermore, the adjustable support leg 4 is made of aluminum alloy material. The adjustable support leg 4 uses a mechanical screw adjustment mechanism and can be telescopically adjusted according to the on-site situation to keep the support tray 2 horizontal, thereby adapting to the on-site landslide and debris flow deposits to the greatest extent. Through the above adjustable support leg 4, the horizontal adjustment of the entire support tray 2 can be conveniently realized.

[0031] Furthermore, a horizontal bubble 3 for displaying the levelness is arranged at the top of the support tray 2. Through the above horizontal bubble 3, the levelness of the support tray 2 can be displayed, thereby ensuring the verticality of the subsequent lowering of the probe 10.

On the opposite side of the recording roller 13, pressing rollers 14 are symmetrically and rotatably installed through an adjusting frame 15. The adjusting frame 15 is adjustably installed on the housing 12 through an adjusting member 16. The adjusting member 16 and the spring pressing mechanism 17 are adjustably installed inside the housing 12 and are used to adjust the pressing degree of the pressing roller 14 on the cable 11. Through the above-mentioned lifting controller 5, the synchronous lowering of the cable 11 can be achieved. Furthermore, during the lowering process, the lowering length of the cable 11 is synchronously displayed.

[0033] Furthermore, mounting holes for installing the detection tube 7 are respectively machined at the upper and lower ends of the housing 12, and the end of the detection tube 7 extends out of the housing 12 by a certain length. Through the above-mentioned detection tube 7, the purpose of reliably guiding the cable 11 is achieved, and further, the vertical lowering of the cable 11 is ensured.

[0034] Furthermore, the cable 11 is wound around the cable unwinding bracket 24. During the lowering process of the cable 11, it contacts the outer walls of the pressing roller 14 and the recording roller 13 and synchronously drives the recording roller 13 to rotate. Through the above specific structure, it is ensured that during the lowering process of the cable 11, the recording roller 13 can be synchronously driven to rotate. Furthermore, the length of the cable 11 is recorded through the recording roller 13, so as to facilitate the measurement of the depth of the exploration hole and ensure that the collected image is adapted to the depth of the exploration hole.

[0035] Furthermore, the product of the circumference c of the recording roller 13 and the number of rotations n is the lowering distance m of the probe 10. Through the above size relationship, the lowering length of the cable 11 can be conveniently calculated.

[0036] Furthermore, the recording roller 13 is connected to the main control unit 6. A display screen 9 is provided on the main control unit 6, and the display screen 9 can display the product of the circumference c of the recording roller 13 and the number of rotations n. Through the above display screen 9, it is convenient to accurately display Furthermore, the probe 10 includes a probe housing 22, and the end of the probe 10 is a conical structure. The above-mentioned probe housing 22 is mainly made of titanium alloy. Titanium alloy has high strength and low density, good mechanical properties, and excellent toughness and corrosion resistance. Due to the poor processability of titanium alloy and the difficulty of cutting, a small amount of carbon fiber composite material with high pressure resistance, corrosion resistance, dust resistance, and high temperature resistance is used. The overall appearance of the probe 10 is conical.

[0037] Furthermore, the probe 10 is provided with a glass cover 19 made of a polymer resin, and the gas inside the glass cover 19 is evacuated; the glass cover 19 is made of polymer resin glass, which is light in weight, has high light transmittance and impact resistance, and has strong functionality.

[0038] Further, an image sensor 20 for image acquisition is installed inside the probe 10; the image sensor 20 is a solid-state image sensor, which has the characteristics of small volume, light weight, high integration, high resolution, low power consumption, long service life, and low price.

[0039] Further, an infrared rangefinder 23 for monitoring distance is installed inside the probe 10; the infrared rangefinder 23 uses a gallium arsenide light-emitting diode as a light source, and its light intensity changes with the injected electrical signal, having the dual functions of a light source and a modulator.

[0040] Further, the image sensor 20 and the infrared rangefinder 23 are connected to the main control machine 6. Through the above connection method, the acquisition of the image inside the exploration hole and the detection depth can be realized, and subsequent data analysis is facilitated.

[0041] Further, a surrounding light source 21 is installed outside the probe 10; the surrounding light source 21 is used to highlight the changes in the edges and heights of the objects to be measured, highlighting the parts that are originally difficult to see clearly.

[0042] Further, a cleaning device 8 is provided above the probe 10. A wiping ring 18 is installed inside the cleaning device 8 in a matching manner. The wiping ring 18 cooperates with the probe housing 22 to wipe the outer surface of the probe 10. The inner side of the wiping ring 18 closely adheres to the transparent outer side of the probe 10 body and is a kind of ultra-fine fiber composite wire. The fineness of its microfibers with a diameter of 0.4 μm is 1 / 10 of that of real silk, and its special cross-section can more effectively capture dust particles as small as a few micrometers.
