Description

Technical Field

[0001] The invention belongs to the technical field of surrounding rock quality detection, and in particular relates to a spectrum detection device for borehole cracks and a use method thereof. Background Art

[0002] During tunnel excavation and mining, anchoring structures play an important supporting and fixing role in engineering structures such as buildings, bridges, rocks, and tunnels. However, cracks in the anchor holes may affect the strength and stability of the structure. The presence of cracks may weaken and damage the material, thereby reducing the bearing capacity and earthquake resistance of the structure. Especially under high pressure or high load conditions, the expansion and development of cracks may cause the destruction and collapse of the structure. Cracks may also cause the failure of anchor rods or cables, resulting in the influence of the anchoring effect and reducing the tensile bearing capacity of anchor rods or cables. If the cracks continue to expand and develop, the anchor rods or cables may fall off due to failure, resulting in instability and danger of the structure. Cracks may also cause water leakage and consolidation problems. The presence of cracks will lead to the infiltration of groundwater and increase the moisture content of the soil or rock mass. This may lead to reduced stability and increased deformation of the soil or rock mass, further exacerbating the development of cracks and structural instability. By detecting cracks in anchor holes, potential safety hazards can be discovered early, and corresponding measures can be taken to repair or reinforce them to ensure the safety of the structure. This is crucial for selecting the appropriate anchoring solution, determining the load bearing capacity, and predicting the life and reliability of the structure. When cracks appear in the anchor hole, they need to be detected and repaired in a timely manner. By detecting the cracks, it is possible to determine what methods and materials to use for repair to extend the service life of the anchoring system.

[0003] Some traditional crack detection technologies in anchor holes can usually only detect shallow cracks and cannot effectively detect deeper cracks. This is due to signal attenuation and interference, as well as sensor limitations. At the same time, the spatial resolution of most crack detection technologies is relatively low, and they cannot provide sufficient details and accurate crack morphology information. This may lead to certain errors in the judgment and evaluation of cracks, limiting the accurate assessment of engineering safety and stability. In the detection of cracks in anchor holes, different types and forms of cracks may require different detection methods and techniques. However, current technologies often cannot accurately identify cracks of different types and forms, which may lead to inaccurate understanding of the nature and impact of cracks. Crack detection technology requires a long time for data collection and analysis, resulting in slow detection speed. This may limit its application in actual engineering, especially for large-scale projects and situations where rapid detection is required. In a considerable number of cases, it is necessary to monitor the cracks in the anchor hole in real time, as well as respond to their changes and evolution in real time.

[0004] However, current crack detection technologies in anchor holes often fail to meet the requirements of real-time monitoring, which may limit the timely understanding and processing of crack changes. Summary of the invention

DETAILED DESCRIPTION

[0048] Combine the following Figures 1 to 12 The structural schematic diagram of a borehole crack spectrum detection device and a use method thereof provided by the present invention are described.

[0049] Example 1

[0050] like Figure 4 As shown, the spectrum detection device for drilled cracks provided by the present invention mainly includes a main rod body 1, a main body sleeve 3 and a spectrum detection device 5.

[0051] The main body sleeve 3 is sleeved on one side of the main rod body 1, and the other side of the main rod body 1 is detachably connected with the nozzle 2 through a threaded structure.

[0052] Specifically, the nozzle 2 is made of a flexible rubber material, which can deform to absorb impact force, so as to prevent damage to the device when colliding with the hole wall or the bottom of the anchor hole 18. Figure 8 and Fig. 9 As shown, the nozzle 2 includes a cylinder, a hemisphere and a plurality of nozzle protrusions 6, wherein a connection structure matching the main rod body 1 is provided at one end of the cylinder, and the connection structure can be a threaded structure, and the other end of the cylinder is fixedly connected to the hemisphere, and the plurality of nozzle protrusions 6 are evenly distributed on the convex surface of the hemisphere, and each nozzle protrusion 6 is provided with a through hole 7, and the central axis of each through hole 7 passes through the center of the hemisphere, so that the transparent slurry 4 containing white ultrafine silica gel particles can be sprayed out evenly and in multiple directions through the through hole 7.

[0053] like Figure 5 (a) Figure 5 (b) Figure 4 , Figure 8 and Fig. 9 As shown, the first catheter assembly includes four grouting pipes 8 and a pumping structure for delivering a transparent slurry 4 containing white ultrafine silica gel particles into the grouting pipes 8. The four grouting pipes 8 are arranged inside the main rod body 1 and their length direction is consistent with the length direction of the main rod body 1. The four grouting pipes 8 are evenly spaced and distributed along the circumferential direction of the main rod body 1. One end of the four grouting pipes 8 is respectively connected to a through hole 7, and the other end of the four grouting pipes 8 can be connected to the output end of the pumping structure. The pumping structure includes a grouting machine and its accessories. Since the pumping structure is a prior art, its structure is not repeated. The function can be achieved using an existing device. The output pipe of the grouting machine is connected to the grouting pipe 8, which is used to inject the transparent slurry 4 containing white ultrafine silica gel particles into the grouting pipe 8 and spray it out through the through hole 7. Since the multiple through holes 7 are evenly distributed on the convex surface of the hemisphere, the transparent slurry 4 containing white ultrafine silica gel particles sprayed through each through hole 7 can be oriented in different directions, which is convenient for evenly dispersing and spraying the transparent slurry 4 containing white ultrafine silica gel particles. When grouting is not performed, the inlets of the four grouting pipes 8 can be blocked with grout stoppers 25 .

[0054] Specifically, the diameter of the white ultrafine silica gel particles is 75-150 microns. The smaller the particles are, the easier it is for them to penetrate into the cracks 22.

[0055] like Figure 5 (a) Figure 5 (b) and Figure 4 As shown, the second catheter assembly includes a first gas injection structure and a second gas injection structure 13 .

[0056] The first gas injection structure includes four first gas injection pipes 9 arranged inside the main rod body 1, the length direction of the four first gas injection pipes 9 is consistent with the length direction of the main rod body 1, and the four first gas injection pipes 9 are evenly distributed along the circumferential direction of the main rod body 1. One end of the four first gas injection pipes 9 is connected to a through hole 7 respectively, and the other end of the four first gas injection pipes 9 is connected to a high-pressure gas supply component. The high-pressure gas supply component includes a high-pressure air pump and a connecting pipe with one end connected to the output end of the high-pressure air pump. The other end of the connecting pipe is connected to the first gas injection pipe 9. The high-pressure gas supply component is used to provide high-pressure air, and the transparent slurry 4 containing white ultrafine silica gel particles is dispersed and sprayed out under auxiliary pressure. When not in use, the inlet of the four first gas injection pipes 9 can be blocked with a slurry stopper 25.

[0057] As one implementation mode, the plurality of grouting pipes (8) and the plurality of first air injection pipes (9) may also be arranged on the left and right sides of the axis of the main rod body 1, respectively; the plurality of grouting pipes (8) and the plurality of first air injection pipes (9) may also be arranged at intervals.

[0058] like Figure 5 As shown in (c), the second gas injection structure 13 can be set as one group, two groups or three groups, which is specifically determined according to the length of the main rod body 1. Several groups of second gas injection structures 13 are evenly spaced and arranged, such as Figure 3 As shown, two sets of second gas injection structures 13 are provided. Figure 2 Specifically, the second gas injection structure 13 includes a plurality of second gas injection pipes 14 arranged on the outer side of the middle section of the main rod body 1, such as Figure 7 As shown, the central axes of the plurality of second gas injection pipes 14 are all arranged parallel to the central axis of the main rod body 1, and the plurality of second gas injection pipes 14 are evenly arranged in the circumferential direction of the main rod body 1. One end of the plurality of second gas injection pipes 14 is connected to the plurality of first gas injection pipes 9 through a connecting pipe, and the other end is connected to a nozzle 15, which has a plurality of air delivery holes 28. When high-pressure air is delivered through the plurality of air delivery holes 28 on the nozzle 15, pressurization can be assisted, so that the transparent slurry 4 containing white ultrafine silica gel particles is pressurized and injected into the cracks 22 on the hole wall 29 of the surrounding edge 31.

[0059] In order to facilitate the position of the fixing device, a tray 17 is provided at one end of the main sleeve 3 close to the nozzle 2. The main sleeve 3 and the tray 17 are connected and fixed by multiple high-strength bolts 26. The tray 17 includes a tray body, and the middle of the tray body has an inner concave surface, which is arranged toward the nozzle 2. A plurality of mounting holes are opened on the tray 17, and the mounting holes are used to penetrate connecting parts, so as to fix the tray 17 to the surrounding rock 31 around the anchor hole 18.

[0060] The connecting pieces may be bolts or screws.

[0061] Furthermore, for safety reasons, a pressure detection assembly 16 is provided in the middle of the main rod body 1. The pressure detection assembly 16 is electrically connected to the data processor 20 and can detect the pressure inside the pore after grouting in real time to provide a reference for safety.

[0062] The pressure detection component 16 can be implemented by a pressure sensor or other detection components with a pressure detection function.

[0063] Furthermore, in order to prevent the slurry from being retained on the surface of the main rod body 1 , an anti-sticking layer is provided on the surface of the main rod body 1 and the main body sleeve 3 . Specifically, the anti-sticking layer is a non-stick film material 27 .

[0064] Furthermore, in order to prevent the injected composite slurry containing the transparent slurry 4 of white ultrafine silica gel particles from flowing out of the anchor hole 18 , an annular slurry stopper 30 is fixedly mounted on the main sleeve 3 , and the annular slurry stopper 30 is located on the side away from the nozzle 2 .

[0065] In order to detect the composite slurry of transparent slurry 4 containing white ultra-fine silica gel particles filled in the anchor hole, so as to determine the shape of the crack, such as Figure 5 (b) and Fig.12 As shown, a linear moving component is arranged on the surface of the main rod body 1 , and the linear moving component is located at a side away from the main body sleeve 3 . The linear moving component has a moving part, and the moving part is fixedly connected to the spectrum detection device 5 .

[0066] Specifically, the linear moving component includes a slide groove 10 opened on the main rod body 1, and the length direction of the slide groove 10 is consistent with the length direction of the main rod body 1. A motor 11 is fixed in the slide groove 10, and the central axis of the output end of the motor 11 is perpendicular to the length direction of the main rod body 1. A roller is fixed on the output end of the motor 11, and a pull wire 12 is wound around the roller. One end of the pull wire 12 is fixed to the roller, and the other end is fixedly connected to one side of the slider. The other side of the slider is fixedly connected to the side wall of the slide groove 10 through a reset spring. The slider is slidably connected to the slide groove 10, and the spectrum detection device 5 is fixedly connected to the slider. When the motor 11 is started, the slider can be driven to move along the length direction of the slide groove 10 with the spectrum detection device 5. The rotation speed of the motor 11 can be adjusted to control the moving speed of the spectrum detection device 5.

[0067] During use, when the motor 11 rotates, it can drive the roller to rotate synchronously, thereby synchronously changing the length of the pull wire 12, driving the slider and the spectrum detection device 5 to move synchronously. The reset spring is used to provide a balancing reset force to keep the slider moving smoothly.

[0068] As another implementation method, the linear motion component can also be implemented using a linear motor or an electric push rod.

[0069] like Figure 2 and Figure 3 As shown, the spectrum detection device 5 is electrically connected to a data storage device 19 , which can store detection data of the spectrum detection device 5 . The data storage device 19 is electrically connected to a data processor 20 via a connection line 23 , and the data processor 20 is electrically connected to a display 21 .

[0070] like Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, the spectrum detection device 5 is a spectrometer that can emit light of constant wavelength and intensity. After the composite slurry of the transparent slurry 4 containing white ultrafine silica gel particles is injected into the anchor hole 18 and fully penetrated into the anchor hole 18, the motor 11 drives the spectrum detection device 5 to move along the length direction of the slide groove 10. At the same time, the spectrum detection device 5 emits light of constant wavelength and intensity into the anchor hole 18. The white ultrafine silica gel particles in the transparent slurry 4 containing white ultrafine silica gel particles will reflect a certain wavelength of reflected light after being irradiated by the light. The spectrum detection device 5 can detect the position of the particles in the anchor hole 18 based on the reflected light of the white ultrafine silica gel particles, thereby detecting the distance from the inner surface of the anchor hole 18 and the crack to the spectrum detection device 5. After multiple detections, the position data can be calculated using the data processor 20 based on the generated distance data.

[0071] The composite slurry of the transparent slurry 4 containing white ultrafine silica gel particles has the function of changing the color properties in the anchor hole crack 22. After the slurry fills the crack 22 in the anchor hole 18, the spectrum detection device 5 slides evenly along the length direction of the slide groove 10, and emits a continuous spectrum or a specific wavelength of light during the sliding process. Since different colors correspond to different reflection wavelengths and intensities, the spectrum is analyzed and measured. The obtained spectral data is transmitted to the spectrum processor on the spectrum detection device 5 through the connecting line 23, so that the position of the white ultrafine silica gel particles is obtained on the display 21, and then the size and shape of the anchor hole 18 are calculated, thereby achieving the purpose of crack detection.

[0072] like Figure 1 and Figure 2 As shown, the usage and steps are as follows:

[0073] First, an anchor hole 18 is drilled at a pre-marked position of the surrounding rock 31, and the main sleeve 3 is embedded in the anchor hole 18. Then, the output pipe of the grouting machine is connected to the grouting pipe 8, and the second conduit assembly is connected to the output pipe of the high-pressure air pump.

[0074] The composite slurry containing the transparent slurry 4 of the white ultrafine silica gel particles is stirred evenly in the grouting vessel, and then the grouting vessel is closed, the high-pressure air pump and the grouting machine are started, and the composite slurry containing the transparent slurry 4 of the white ultrafine silica gel particles is sprayed onto the surface of the anchor hole 18 through the nozzle 15 and the nozzle 2. Fig.10 and Fig.11 As shown, the motor 11 is started to drive the slider and the spectrum detection device 5 to move along the length direction of the slide slot 10.

[0075] At this time, the spectrum detection device 5 should always be in the on state. The spectrum detection device 5 will detect the distance change data generated by the white ultrafine silica gel particles in the transparent slurry 4 containing white ultrafine silica gel particles that have penetrated into the cracks 22 through the reflected light of the white ultrafine silica gel particles. Each cross-sectional position information of the anchor hole 18 will be recorded and stored in the data storage device 19, and the data will be transmitted to the data processor 20 through the connecting line 23. The data processor 20 is electrically connected to the display 21. The data processor 20 will calculate the distance change data based on the cross-sectional position information, and then re-synthesize it based on the cross-sectional position information. Finally, the data processor 20 can use signal processing, data filtering, three-dimensional imaging and other technologies to draw a three-dimensional map of the anchor hole cracks and display it on the display 21.

[0076] Furthermore, in order to make the composite slurry of the transparent slurry 4 containing white ultrafine silica gel particles distribute quickly and evenly in the anchor hole 18, the nozzle 15 and the nozzle 2 can be rotated by manually rotating the main rod body 1 and the main sleeve 3, so that the transparent slurry 4 containing white ultrafine silica gel particles can be sprayed onto the circumferential surface of the anchor hole 18, so that the slurry can be fully injected into the cracks 22 on the anchor hole 18.

[0077] The above disclosure is only a preferred specific embodiment of the present invention, but the embodiments of the present invention are not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
