Description

Technical Field

[0001] This invention belongs to the field of advanced geological prediction technology, specifically relating to a tunnel geological monitoring TSP borehole layout auxiliary device and its usage method. Background Technology

[0002] Advanced geological forecasting is an indispensable part of road engineering. Its significance lies in: (1) Based on the results of advanced geological forecasting of tunnels, we can grasp the adverse geological conditions in front of the tunnel face and provide suggestions and basis for the adjustment of design and construction plans, construction safety management, and disaster response. (2) Through tunnel monitoring and measurement, we can effectively monitor the tunnel body safety, initial support and surrounding rock deformation during the tunnel construction process, and make predictions on possible dangers, initial support encroachment, large deformation of surrounding rock, etc., to ensure the safety of tunnel construction. Through measurement data, we can summarize the deformation law of different surrounding rocks and provide reasonable reserved deformation parameter suggestions under different surrounding rock conditions, providing a basis for the precise construction and dynamic management of the project. (3) Through the feedback of tunnel monitoring and measurement and advanced geological forecasting results, we can propose the best construction methods and support structure construction measures that meet the specific engineering requirements and geological conditions, providing a basis for the dynamic design of the tunnel. (4) By inspecting the quality of the main tunnel structure, we can ensure that the project quality is controllable and effectively promote the improvement of project quality. Through the analysis of inspection data, we can put forward suggestions for handling quality problems and adjusting construction methods to reduce project quality fluctuations and lay the foundation for the smooth completion of the project.

[0003] TSP (Tunnel Seismic Prediction System) detection is one of the main methods for advanced geological prediction. It determines the location of blast holes on the left or right sidewall based on the strike of the rock strata within the tunnel. The first blast hole is placed near the tunnel face, followed by subsequent blast holes at regular intervals, for a total of 24 blast holes. A 15-20m measurement is taken from the 24th blast hole towards the tunnel entrance, and a seismic wave receiving hole is placed on each of the left and right sidewalls. Each blast hole uses a small amount of explosive to artificially generate a seismic wave signal. The resulting seismic wave signal is quickly received and recorded by the receiving probe in the receiving hole. This process continues until all 24 blast holes have been blasted.

[0004] When setting up 24 excitation holes in this process, the 24 excitation holes need to be arranged in a straight line. Therefore, the location of the blast holes needs to be manually measured and marked during the layout, which is a tedious, time-consuming and labor-intensive process. Summary of the Invention

[0005] To address the problem that the existing technology involves manually measuring and marking the location of blast holes, which is a rather cumbersome process, this invention provides a tunnel geological monitoring TSP blast hole layout auxiliary device and its usage method.

[0006] The technical solution adopted in this invention is as follows:

[0007] A tunnel geological monitoring (TSP) borehole layout auxiliary device includes:

[0008] A moving mechanism is used to move linearly in a drilling area on a tunnel wall. The moving mechanism includes a first base and a second base. The first base can slide linearly on the second base, and the second base can slide linearly on the first base.

[0009] A marking mechanism is used to drill holes in a perforated area on the tunnel wall to form blast hole marking holes. The marking mechanism includes a first drilling component, a second drilling component, and a third drilling component, which are respectively disposed on a first base or a second base.

[0010] By adopting this technical solution, the present invention provides a TSP borehole layout auxiliary device that can move autonomously on the tunnel wall through the cooperation of a first base and a second base. Through the cooperation of a first drilling component, a second drilling component, and a third drilling component on the first and second bases, it achieves autonomous drilling on the tunnel wall, and the spacing between the holes is also fixed (1.5m). This eliminates the need for manual measurement and marking of the drilling positions, greatly reducing the workload of manual labor and ensuring the accuracy of marking.

[0011] Preferably, the first base is provided with a straight sliding groove, the second base is slidably disposed in the first base, and one end of the second base extends out from one end of the first base;

[0012] The first base has a connection port on its side that communicates with the straight slide groove. The first punch is connected to the end of the first base away from the protruding end of the second base. The second punch and the third punch are respectively connected to the two ends of the second base through the connection port. The first punch, the second punch, and the third punch are located at the same horizontal level and on the same side of the first base.

[0013] The first, second, and third drilling components all include a drilling drill.

[0014] After adopting this technical solution, the second base can slide linearly relative to the first base through the straight sliding groove in the first base. The first, second, and third punching parts are located at the same horizontal height and on the same side of the first base, which satisfies the punching requirements.

[0015] Preferably, the diameter of the drilling drill is 10-15mm; the distance from the central axis of the drilling drill of the second drilling component to the central axis of the drilling drill of the third drilling component is 1.5m; when the sliding stroke of the second base is at its maximum, the distance from the central axis of the drilling drill of the first drilling component to the central axis of the drilling drill of the second drilling component is 1.5m; when the sliding stroke of the second base is 0, the distance from the central axis of the drilling drill of the first drilling component to the central axis of the drilling drill of the second drilling component is 10-30mm.

[0016] After adopting this technical solution, the spacing between two adjacent blast hole marking holes can be 1.5m after setting the size, which meets the drilling requirements.

[0017] Preferably, the first drilling component includes a base with a mounting groove. A rotatable mechanism is provided in the mounting groove. The drilling drill is connected to the mounting groove through the rotatable mechanism. The rotatable mechanism includes a fixed shaft and a rotating shaft. A first half gear is fixedly provided on the rotating shaft, and a second half gear is rotatably provided on the fixed shaft. The first half gear and the second half gear mesh. The rotating shaft is connected to the output shaft of a first motor, and the first motor has a self-locking structure.

[0018] The second half gear is connected to an auger drill located outside the mounting slot. The auger drill includes the drilling drill and a drive mechanism for driving the drilling drill to rotate and move forward or backward while rotating.

[0019] After adopting this technical solution, the blast hole needs to be tilted downward by 10-20° when drilling. Therefore, in order to improve the marking effect, the present invention can drive the first half gear to rotate through the first motor, and the first half gear drives the second half gear to rotate, thereby driving the auger drill to tilt downward, so that the resulting blast hole marking hole also has a certain degree of inclination.

[0020] Preferably, the first, second, and third punched parts are identical in size and structure.

[0021] Preferably, at least one rack is provided on the second base, and the rack is arranged along the length direction of the second base.

[0022] A gear that meshes with the rack is provided on the side of the straight groove away from the first perforated part, and a second motor with an output shaft connected to the gear is provided on the first base.

[0023] After adopting this technical solution, the second motor can drive the gear to rotate. The forward and reverse rotation of the gear can respectively drive the first base to slide on the second base or drive the second base to slide on the first base.

[0024] Preferably, one end of the second base is connected to a limiting block disposed in a straight slide groove, and a roller is disposed on the contact surface between the limiting block and the straight slide groove.

[0025] By adopting this technical solution, the friction between the second base and the first base can be reduced by setting rollers, thereby reducing energy consumption.

[0026] Preferably, a measuring tape is provided at the end of the first base where the first drilling component is located, and the horizontal height of the tape's outlet is equal to the horizontal height of the central axis of the drilling drill of the first drilling component.

[0027] After adopting this technical solution, the height of the first base from the ground can be measured with a tape measure, thereby marking the height of the blast hole marking hole. At the same time, the tape measure can also be pulled to the opposite tunnel wall to mark the position of the opposite receiving hole marking hole.

[0028] A method for using a tunnel geological monitoring TSP borehole layout auxiliary device includes the following steps:

[0029] S1. Start the initialization program: Mark the first drilling position on the drilling area on the tunnel wall, then align the first drilling component at the far end with the first drilling position, manually fix the tunnel geological monitoring TSP borehole layout auxiliary device, and then manually start the initialization program.

[0030] S2. Perform the initialization procedure: Start the first, second, and third drilling components to drill into the tunnel wall and obtain three blast hole marker holes;

[0031] S3. Perform the normal drilling procedure: The first drilling component located on the first base rotates in the opposite direction and retracts until the first drilling component disengages from the first blast hole marking hole. Then, the first base is driven to move on the second base until the first base overlaps with the second base and stops moving. The first drilling component is restarted to drill a hole near the second blast hole marking hole to obtain the marking auxiliary hole.

[0032] The second and third punching parts on the second base rotate in opposite directions and retract until the second and third punching parts are respectively disengaged from the second and third blast hole marking holes.

[0033] The second base is driven to move on the first base until it slides to its maximum stroke and then stops. The second and third drilling components are then started again to drill holes, resulting in the fourth and fifth blast hole marking holes. This process is repeated until 24 blast hole marking holes are obtained.

[0034] Preferably, the process also includes drilling the receiving hole marker holes: After drilling the 24 blast hole marker holes, the tunnel geological monitoring TSP blast hole layout auxiliary device is removed. Then, the first drilling component is aligned with the position near the last blast hole marker hole, and the first drilling component is started to drill, obtaining the first moving hole. Then, the receiving hole marker hole drilling program is started: the second base is driven to move on the first base until the second base slides to the maximum stroke on the first base and then stops moving. The third drilling component at the end is started to drill, obtaining the second moving hole. The second drilling component is not started. The first drilling component rotates in the opposite direction and retracts until the first drilling component disengages from the first moving hole. Then, the first base is driven to move on the second base until the first base overlaps with the second base and then stops moving. The first drilling component is started again to drill, obtaining the third moving hole. This process is repeated until the distance from the last moving hole to the last blast hole marker hole is 15-20m.

[0035] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0036] This invention provides a TSP borehole layout auxiliary device that can move autonomously on the tunnel wall through the cooperation of a first base and a second base. The device achieves autonomous drilling on the tunnel wall through the cooperation of a first drilling component, a second drilling component, and a third drilling component on the first and second bases. The spacing between the holes is also fixed (1.5m), thus eliminating the need for manual measurement and marking of the drilling positions, greatly reducing the workload of manual labor, and ensuring the accuracy of marking.

Therefore, they should not be construed as limitations on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0046] like Figure 1-5 As shown, a tunnel geological monitoring (TSP) borehole layout auxiliary device includes:

[0047] The moving mechanism is used to move linearly in the drilling area on the tunnel wall. The moving mechanism includes a first base 1 and a second base 2. The first base 1 can slide linearly on the second base 2, and the second base 2 can slide linearly on the first base 1. It should be noted that in order to ensure that only one of the first drilling component 3, the second drilling component 4, and the third drilling component 5 can provide stable support for the entire device, except for the drilling drill 303 which needs to drill holes, the rest of the structure is made of lightweight materials as much as possible. The drilling drill 303 is made of hard alloy, such as high-speed steel, to maintain its drilling effect.

[0048] A marking mechanism is used to drill holes in the perforation area of ​​the tunnel wall to form blast hole marking holes. The marking mechanism includes a first drilling component 3, a second drilling component 4, and a third drilling component 5, which are respectively disposed on a first base 1 or a second base 2. In this embodiment, as shown... Figure 1 The first base 1 shown is provided with a straight sliding groove, and the second base 2 is slidably disposed in the first base 1, with one end of the second base 2 extending out from one end of the first base 1;

[0049] The first base 1 has a connection port 6 on its side that communicates with the straight groove. The first drilling component 3 is connected to the end of the first base 1 away from the protruding end of the second base 2. The second drilling component 4 and the third drilling component 5 are respectively connected to the two ends of the second base 2 through the connection port 6. The first drilling component 3, the second drilling component 4 and the third drilling component 5 are located at the same horizontal level and on the same side of the first base 1. The first drilling component 3, the second drilling component 4 and the third drilling component 5 all include a drilling drill 303. It should be noted that the drilling drill 303 is a spiral drill, that is, the side wall of the drilling drill 303 is spiral, so that the drilling drill 303 can play a good fixing role after drilling into the tunnel wall. The depth of the spiral groove on the spiral drill can be set as needed. Generally speaking, the greater the depth of the spiral groove, the better the connection effect.

[0050] In one embodiment, the diameter of the drilling drill 303 is 10-15mm. In this embodiment, the diameter of the drilling drill 303 is set to 10mm, which serves a clear marking function, reduces drilling difficulty, and provides stable support for the entire device by driving the drilling drill 303 into the tunnel sidewall. The distance from the central axis of the drilling drill 303 of the second drilling component 4 to the central axis of the drilling drill 303 of the third drilling component 5 is 1.5m. When the sliding stroke of the second base 2 is at its maximum, the drilling of the first drilling component 3... The distance from the central axis of drill 303 to the central axis of drill 303 of the second drilling component 4 is 1.5m; when the sliding stroke of the second base 2 is 0, the distance from the central axis of drill 303 of the first drilling component 3 to the central axis of drill 303 of the second drilling component 4 is 10-30mm. This setting is to ensure that the distance between the drilled auxiliary marking hole and the blast hole marking hole is relatively close, so that the overall size of the auxiliary marking hole and the blast hole marking hole is smaller than the size of a single blast hole. In this way, the auxiliary marking hole will not exist after the blast hole is drilled, and it will not affect the monitoring effect (e.g., Figure 6 (As shown).

[0051] In one embodiment, such as Figure 2 and Figure 4As shown, the first drilling component 3 includes a base 306, on which a mounting groove 304 is provided. A rotatable mechanism is provided in the mounting groove 304. The drilling drill 303 is connected to the mounting groove 304 through the rotatable mechanism. The rotatable mechanism includes a fixed shaft 307 and a rotating shaft 308. A first half-gear 309 is fixedly provided on the rotating shaft 308, and a second half-gear 305 (which can rotate on the fixed shaft 307) is rotatably provided on the fixed shaft 307. The first half-gear 309 and the second half-gear 305 mesh. The rotating shaft 308 is connected to the output shaft of a first motor 301. 301 has a self-locking structure; it should be noted that the first motor 301 is a reciprocating motor that can rotate forward and reverse, thereby driving the drilling drill 303 to tilt upward or downward; the first motor 301 is fixedly mounted on the base 306, and its output shaft is fixedly connected to the rotating shaft 308. The output shaft can drive the rotating shaft 308 to rotate. Since the first half gear 309 is fixedly connected to the rotating shaft 308, the first half gear 309 can rotate with the rotating shaft 308; the two ends of the fixed shaft 307 are fixedly connected to the side wall of the mounting groove 304. The second half gear 305 can rotate relative to the fixed shaft 307, so the first half gear 309 can drive the second half gear 305 to rotate.

[0052] The second half gear 305 is connected to an auger drill located outside the mounting slot 304. It should be noted that the structure and function of the auger drill are consistent with existing technology, and the auger drill includes the drilling drill 303 and a drive mechanism 302 for driving the drilling drill 303 to rotate and move forward or backward during rotation. The first drilling component 3, the second drilling component 4, and the third drilling component 5 are identical in size and structure.

[0053] When drilling blast holes, it is necessary to tilt downwards by 10-20°. Therefore, in order to improve the marking effect, the present invention can drive the first half gear 309 to rotate through the first motor 301, and the first half gear 309 drives the second half gear 305 to rotate, thereby causing the auger drill to tilt downwards, so that the resulting blast hole marking hole also has a certain degree of inclination.

[0054] In one embodiment, at least one rack 7 is provided on the second base 2, as shown in this embodiment. Figure 1 and Figure 5 As shown, a rack 7 is provided, and the rack 7 is provided on the top of the second base 2. Its length is similar to the length of the second base 2. The rack 7 is arranged along the length direction of the second base 2.

[0055] like Figure 5As shown, a gear 8 that meshes with the rack 7 is provided on the side of the straight groove away from the first perforated part 3. A second motor with an output shaft connected to the gear 8 is provided on the first base 1. The second motor has a self-locking structure and is a reciprocating motor that can rotate forward and reverse. The gear 8 can be driven to rotate forward or reverse by the second motor, thereby realizing the sliding of the first base 1 on the second base 2 or the sliding of the second base 2 on the first base 1.

[0056] In one embodiment, one end of the second base 2 is connected to a limiting block 9 disposed within a straight groove. A roller is provided on the contact surface between the limiting block 9 and the straight groove. Specifically, at least the bottom of the limiting block 9 is provided with a roller. By providing the roller, the friction between the second base 2 and the first base 1 can be reduced, thereby lowering the energy consumption required for driving.

[0057] In one embodiment, a measuring tape is installed at the end of the first base 1 where a first drilling component 3 is located. The horizontal height of the measuring tape's outlet is equal to the horizontal height of the central axis of the drilling drill 303 of the first drilling component 3. Specifically, the measuring tape can be installed at the bottom of the first base 1. The measuring tape can be used to measure the height of the first base 1 from the ground, thereby marking the height of the blast hole marking hole. At the same time, the measuring tape can also be pulled to the opposite tunnel wall to mark the position of the opposite receiving hole marking hole.

[0058] like Figure 1-5 As shown, a method for using a tunnel geological monitoring TSP borehole layout auxiliary device includes the following steps:

[0059] S1. Start the initialization program: The operator marks the first drilling position on the drilling area on the tunnel wall, then aligns the first drilling part 3 at the far end with the first drilling position, and manually fixes the tunnel geological monitoring TSP borehole layout auxiliary device, and then manually starts the initialization program (start button).

[0060] S2. Perform the initialization procedure: Start the first drilling component 3, the second drilling component 4 and the third drilling component 5 to drill three blast hole marker holes in the drilling area on the tunnel wall, thereby fixing the tunnel geological monitoring TSP blast hole layout auxiliary device. The operator ends the manual fixing.

[0061] S3. Perform the normal drilling procedure: The first drilling component 3 located on the first base 1 rotates in the opposite direction and retracts until the first drilling component 3 disengages from the first blast hole marking hole. Then, the first base 1 is driven to move on the second base 2 until the first base 1 and the second base 2 overlap and stop moving. The first drilling component 3 is restarted to drill a hole near the second blast hole marking hole to obtain the marking auxiliary hole.

[0062] The second punching member 4 and the third punching member 5 on the second base 2 rotate in opposite directions and retract until the second punching member 4 and the third punching member 5 disengage from the second blast hole marking hole and the third blast hole marking hole, respectively.

[0063] The second base 2 is driven to move on the first base 1 until it slides to its maximum stroke and then stops moving. The second drilling component 4 and the third drilling component 5 are then started again to drill holes, resulting in the fourth and fifth blast hole marking holes. This process is repeated until 24 blast hole marking holes are obtained.

[0064] In one embodiment, the method further includes drilling the receiving hole marker holes: after drilling the 24 blast hole marker holes, the operator manually fixes the tunnel geological monitoring TSP blast hole layout auxiliary device, and reverses and retracts the first drilling component 3, the second drilling component 4, and the third drilling component 5. Then, the first drilling component 3 is aligned with the position near the last blast hole marker hole, and the first drilling component 3 is started to drill, obtaining the first moving hole. Then, the receiving hole marker hole drilling program is started: the second base 2 is driven to move on the first base 1 until the second base 2 slides on the first base 1 to the maximum position. After a large sliding stroke, the movement stops, and the third drilling component 5 at the end starts drilling to obtain the second moving hole. The second drilling component 4 does not start. The first drilling component 3 rotates in the opposite direction and retracts until it disengages from the first moving hole. Then, the first base 1 is driven to move on the second base 2 until the first base 1 overlaps with the second base 2 and stops moving. The first drilling component 3 is started again to drill to obtain the third moving hole. This process is repeated until the distance from the last moving hole to the last blast hole marking hole is 15-20m. This last moving hole is the receiving hole marking hole.

[0065] In an embodiment equipped with a measuring tape, a communicating sliding groove can be further provided at the bottom of the first base 1 and the second base 2, and a sliding block can be provided in the sliding groove. The measuring tape is placed on the sliding block. After obtaining the receiving hole marking hole on the side adjacent to the blast hole marking hole, the sliding block can be slid so that the measuring tape reaches directly below the punching member that punched the receiving hole marking hole. Then, the measuring tape under the first base 1 is pulled out and pulled to the opposite side of the receiving hole marking hole to mark the position. This position is the position of another receiving hole marking hole.

[0066] The embodiments described above merely illustrate specific implementation methods of this application, and while the descriptions are detailed and specific, they should not be construed as limiting the scope of protection of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the technical solution of this application, and these modifications and improvements all fall within the scope of protection of this application.
