Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of tunnel karst detection, and particularly relates to a double-lane tunnel karst combined detection system based on geological radar and infrared detection. BACKGROUND

[0002] In tunnel geological prediction, infrared technology is often combined with geological radar, seismic wave reflection method, etc. At present, it is mainly applied to 5-30m shallow karst detection. Deep karst needs to be combined with other technologies. Infrared detection technology can effectively detect and predict karst development by analyzing the infrared radiation characteristics of karst areas. Karst areas will produce unique infrared radiation characteristics due to groundwater activity. Infrared thermal imager belongs to intelligent sensor, intelligent sensing system and intelligent sensing element. By capturing these radiation differences, it can identify abnormal bodies such as water-bearing rock layers and karst caves. Ground penetrating radar can realize the detection of underground karst structure without damaging the ground. Just like doctors use X-ray to perform perspective examination on human body, ground penetrating radar "perspects" the earth, does not interfere with the original geological environment of the underground, but can clearly "see" the underground situation.

[0003] In the prior art, when using geological radar and infrared detection technology to detect tunnel karst, the geological radar and infrared detection need to be moved to detect the ground and wall of the tunnel on the cross section of a tunnel. In this process, human intervention is time-consuming and laborious. Electric drive cannot ensure that the geological radar can move closely along the ground, and it is easy to produce missed areas.

[0009] Optionally, the winding shaft of the winding seat is wound with a pull rope, and the pull ropes on the winding seats of the two side plates are respectively fixedly connected with the two ends of the sliding rail.

[0010] Optionally, the mounting assembly further comprises: a first screw rod, a second motor, a second screw rod, a screw block, a first screw rod is rotatably installed in the vertical frame on one side of the ground penetrating radar detection device, a second motor is fixedly connected with the output end of the first screw rod, and the top of the vertical frame is fixed with a second motor corresponding to the position of the screw rod, the two ends of the movable frame are threadedly sleeved on the surface of the first screw rod; wherein the top of the sliding frame is rotatably installed with a second screw rod through a bearing frame, and a screw block is threadedly sleeved on the surface of the second screw rod.

[0011] Optionally, two sliding frames are provided with transmission belts at one end away from the push plate, and two pulleys of the transmission belts are fixedly connected with the second screw.

[0012] Optionally, a bidirectional electric push rod is fixed on the surface of the ground penetrating radar detection device near the transmission belt, a plug hole is formed on the side of the screw block corresponding to the bidirectional electric push rod, and the two elongated ends of the bidirectional electric push rod are inserted into the plug hole.

[0013] Optionally, the two elongated ends of the bidirectional electric push rod are fixed with connecting frames, and the two connecting frames are arranged in a staggered manner.

[0014] Optionally, the infrared detection assembly further comprises a mounting plate, a rotating shaft, an anti-collision plate and an infrared sensor, the top of the spring telescopic plate is provided with a mounting plate, the bottom of the mounting plate is provided with a rotating shaft, and the elongated end of the spring telescopic plate is rotatably connected with the mounting plate through the rotating shaft and the torsion spring.

[0015] Optionally, the bottom of the screw block is fixed with a right-angle frame, and the right-angle frame penetrates out of the bottom of the sliding rail, and the right-angle frame is fixedly connected with the bottom of the spring telescopic plate.

[0016] The technical scheme provided by the present disclosure can include the following beneficial effects: 1、The first motor drives the two winding seats on the side plate to rotate, the first motor on the two vertical plates winds one and unwinds one, thereby driving the sliding frame to move, the sliding frame cooperates with the mounting assembly, the intermittent movement of the ground penetrating radar detection device can be realized, and each movement is adjacent, the closeness of tunnel ground detection can be maintained, after the device is moved to the specified position of the tunnel, the first brake plate is lowered to contact the tunnel ground through the first electric push rod, the device is braked, convenient for detection, after the first brake plate is retracted, the device can be moved through the vertical rod and the storage plate and the plug-in plate unfolded on the vertical rod, and the pulley at the bottom of the side plate can facilitate the movement of the device along the ground. 2. Initially, the push plate is positioned at the front end of the ground-penetrating radar (GPR) detection device. After the GPR device moves with the rotation of the second screw, the push plate is positioned at the rear end of the GPR device. At this point, the GPR device can continue to descend without interference from the push plate at the bottom, and the detection positions of the two GPR devices are adjacent, allowing for segmented testing of the straight cross-section of the tunnel surface. After the GPR device moves from one end of the second screw to the other, the extended end of the bidirectional electric push rod retracts and separates from the screw block. Because the two extended ends of the bidirectional electric push rod are connected by a connecting frame with second brake plates in opposite directions, simply put, when the two extended ends of the bidirectional electric push rod retract, the connecting frame moves to both sides, and the two second brake plates approach the corresponding receiving plate and insert plate respectively. The friction between the second brake plates and the receiving plate and insert plate releases the pressure on the ground surface, thus improving the accuracy of the test. The braking of the radar detection device facilitates stability during the descent and close-to-ground testing of the ground-penetrating radar. At this time, the extended end of the bidirectional electric push rod separates from the screw block, allowing the sliding frame to slide along the inner side of the buckle frame via the pull rope. Simultaneously, the rotation of the second screw resets the screw block, and the sliding frame moves the same distance as the ground-penetrating radar. The screw block then aligns again with one side of the bidirectional electric push rod of the ground-penetrating radar. In simple terms, first, based on the length of the second screw, the ground-penetrating radar is moved the same distance. Then, the pull rope moves the sliding frame separately by the same distance. After the screw block is reset, it can be reconnected to the bidirectional electric push rod, facilitating the subsequent movement of the ground-penetrating radar. The sliding frame and buckle frame use a common sliding groove connection structure (not shown in the drawing), ensuring that the sliding frame and buckle frame will not separate due to the individual movement of the sliding frame. 3. When the second motor drives the first screw to rotate, the moving frame moves along the inside of the vertical frame in a threaded engagement with the first screw, thereby lowering the ground-penetrating radar detection device and bringing the detection end closer to the ground for detection. During the movement, the ground-penetrating radar detection device is raised until it is higher than the top of the push plate. The two extended ends of the bidirectional electric push rod are inserted into the insertion holes of the screw block. The motor drives the transmission belt to make the two second screws rotate synchronously. The screw block moves along the top of the sliding frame in a threaded engagement with the second screw. Because the bidirectional electric push rod is inserted into the screw block, the ground-penetrating radar detection device will move horizontally along with the installation components. The distance moved is the length of the second screw. Since the top of the push plate does not exceed the bottom detection end of the ground-penetrating radar detection device, the ground-penetrating radar detection device will not be interfered with by the push plate when it moves. 4. Due to the fixed connection between the right-angle frame and the bottom of the spring telescopic plate, after the bidirectional electric push rod is inserted into the screw block, the motor drives the second screw to rotate. Through the transmission belt, the two second screws rotate synchronously. The screw block and the second screw are threaded together, driving the right-angle frame to move along the inside of the sliding frame. The spring telescopic plate also moves synchronously. The infrared sensor on the mounting plate detects the tunnel wall. Because the tunnel wall is curved, the anti-collision plate makes contact with the inner wall during this process. The telescopic nature of the spring telescopic plate keeps the infrared sensor at a certain distance from the wall for detection. At the same time, the anti-collision plate protects the infrared sensor. The connection between the right-angle frame and the spring telescopic plate can avoid interference from the mounting components during movement.

[0019] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 10As shown in the figure, this disclosure proposes a combined karst detection system for a two-lane tunnel based on ground-penetrating radar and infrared detection, comprising: a side plate 1, wherein two sets of side plates 1 are provided, and a vertical rod 13 is fixed to the back of the side plate 1; a storage plate 11, wherein storage plates 11 are fixed to both inner ends of the side plate 1 and the top of the vertical rod 13, and insert plates 12 are slidably inserted into the two storage plates 11, the side plate 1, the storage plate 11 and the insert plate 12 form a frame structure, and the tops of the storage plate 11 and the insert plate 12 are on the same plane; and a ground-penetrating radar detection device 2, wherein a detection end 21 is provided at the bottom of the ground-penetrating radar detection device 2, and the ground-penetrating radar detection device 2 is set in the frame. The internal structure includes: mounting component 3, which includes a vertical frame 31. The ground-penetrating radar detection device 2 has vertical frames 31 on both sides corresponding to the storage plate 11. A movable frame 33 is fixedly sleeved on the surface of the ground-penetrating radar detection device 2, and the two ends of the movable frame 33 are slidably connected to the inside of the vertical frame 31. A top plate 36 is fixedly fixed to the top of the movable frame 33, and the top plate 36 is fixedly connected to the ground-penetrating radar detection device 2. A buckle frame 32 is fixedly fixed to the bottom of the vertical frame 31, and the buckle frame 32 is slidably fastened to the top of the storage plate 11; a sliding frame 37 is slidably installed on the inner side of the buckle frame 32 facing the ground-penetrating radar detection device 2. The outer end of the buckle frame 32 is inwardly... A sponge pad 318 is fixed to the wall. A push plate 315 is provided at the bottom front end of the ground-penetrating radar detection device 2, and fixing plates 316 are fixed to the top of both sides of the push plate 315. The fixing plates 316 are fixedly connected to the edge of the sliding frame 37. An infrared detection assembly 4 is provided, which includes two sets of spring telescopic plates 41. The two sets of spring telescopic plates 41 are located on both sides of the ground-penetrating radar detection device 2, and the spring telescopic plates 41 are located at the end of the sliding frame 37 away from the push plate 315. The device is moved to the position to be detected, the storage plate 11 and the insert plate 12 are unfolded, and the frame size composed of the storage plate 11, the insert plate 12 and the side plate 1 is adjusted to make Its width is consistent with that of the tunnel. The receiving plate 11 and the insert plate 12 are locked with bolts. The ground-penetrating radar detection device 2 is installed inside the mounting assembly 3. The mounting assembly 3 slides along the top of both sides of the frame composed of the receiving plate 11, the insert plate 12 and the side plate 1. The ground-penetrating radar detection device 2 detects the tunnel ground in sections. Each time it detects, the ground-penetrating radar detection device 2 descends close to the ground. It uses existing ground-penetrating radar detection technology to detect the karst of the tunnel. At the same time, it uses existing infrared intelligent sensors, infrared intelligent sensing systems and infrared intelligent sensing element technology. The infrared detection assembly 4 performs infrared detection on the arc-shaped interior of the tunnel to maintain the synchronization of the ground-penetrating radar detection device 2 with the ground detection.

[0021] like Figure 3As shown, in some embodiments, a first electric push rod 17 is fixed on the surface of the vertical rod 13 near the side plate 1, and a first brake plate 18 is fixed to the extended end of the first electric push rod 17; wherein, a plurality of pulleys 14 are rotatably mounted on the bottom of the side plate 1 through bearings.

[0022] It is understandable that after the device is moved to the designated position in the tunnel, the first electric push rod 17 drives the first brake plate 18 to descend and contact the tunnel ground, braking the device to facilitate detection. After the first brake plate 18 is retracted, the device can be moved by the vertical rod 13 and the storage plate 11 and insert plate 12 that unfold on the vertical rod 13. The pulley 14 at the bottom of the side plate 1 can facilitate the movement of the device along the ground.

[0023] like Figure 3 , Figure 4 ,and Figure 5 As shown, in some embodiments, take-up seats 15 are rotatably mounted on both sides of the top of the side plate 1, and the take-up seats 15 and the storage plate 11 are in a straight line. The two take-up seats 15 on the top of the side plate 1 are fixedly connected by a shaft. The outer end of the side plate 1 is fixed with a first motor 16, and the output end of the first motor 16 is fixedly connected to the shaft of the two take-up seats 15. A pull rope 19 is wound on the take-up shaft of the take-up seat 15, and the pull ropes 19 on the two take-up seats 15 of the side plate 1 are respectively fixedly connected to the two ends of the slide rail.

[0024] It is understandable that the first motor 16 drives the two winding seats 15 on the side plate 1 to rotate. The first motor 16 on the two vertical plates winds up one and unwinds the other, thereby driving the sliding frame 37 to move. The sliding frame 37 cooperates with the mounting component 3 to realize the intermittent movement of the ground radar detection device 2. Each movement is adjacent, which can maintain the tightness of the detection of the tunnel surface.

[0025] like Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, in some embodiments, the mounting assembly 3 further includes: a first screw 34, a second motor 35, a second screw 38, and a screw block 310. The first screw 34 is rotatably mounted inside the vertical frame 31 on one side of the ground-penetrating radar detection device 2, and the second motor 35 is fixed at the top of the vertical frame 31 corresponding to the screw position. The output end of the second motor 35 is fixedly connected to the first screw 34. The two ends of the movable frame 33 are threaded onto the surface of the first screw 34. The top of the sliding frame 37 is rotatably mounted with the second screw 38 via a bearing bracket, and a screw block 310 is threaded onto the surface of the second screw 38. A transmission device is installed at the end of each of the two sliding frames 37 away from the push plate 315. The transmission belt 39 has two pulleys fixedly connected to the second screw 38. A bidirectional electric push rod 311 is fixed on the surface of the ground-penetrating radar detection device 2 near the transmission belt 39. The screw block 310 has an insertion hole 317 on one side corresponding to the bidirectional electric push rod 311, and the two extended ends of the bidirectional electric push rod 311 are inserted into the insertion hole 317. The two extended ends of the bidirectional electric push rod 311 are fixed with connecting brackets 312, and the two connecting brackets 312 are staggered. The other end of the connecting bracket 312 is fixed with a second brake plate 313, and the second brake plate 313 makes frictional contact with the inner wall of the receiving plate 11 or the insertion plate 12 after the connecting bracket 312 moves.

[0026] It should be noted that when the second motor 35 drives the first screw 34 to rotate, the moving frame 33 moves along the inside of the vertical frame 31 with the threaded engagement of the first screw 34, thereby driving the ground-penetrating radar detection device 2 to descend, bringing the detection end 21 closer to the ground for detection. During the movement, the ground-penetrating radar detection device 2 is raised until it is higher than the top of the push plate 315. The two extended ends of the bidirectional electric push rod 311 are inserted into the insertion holes 317 of the screw block 310. The motor drives the transmission belt 39 to make the two second screws 38 rotate synchronously. The screw block 310 moves along the top of the sliding frame 37 with the threaded engagement of the second screws 38. Because the bidirectional electric push rod 311 is inserted into the screw block 310, the ground-penetrating radar detection device 2 will move horizontally with the mounting assembly 3. The distance moved is the length of the second screw 38. Since the top of the push plate 315 does not exceed the bottom detection end 21 of the ground-penetrating radar detection device 2, the ground-penetrating radar detection device 2 will not be interfered with by the push plate 315 during movement. At the same time, as Figure 5As shown, initially, the push plate 315 is at the front end of the ground-penetrating radar detection device 2. After the ground-penetrating radar detection device 2 moves with the rotation of the second screw 38, the push plate 315 is positioned at the rear end of the ground-penetrating radar detection device 2. At this point, the ground-penetrating radar detection device 2 can continue to descend without interference from the push plate 315 at its bottom, and the detection positions of the two sections of the ground-penetrating radar detection device 2 are adjacent, thus enabling segmented testing of the straight line of the tunnel's surface cross-section. This process is repeated as the ground-penetrating radar detection device 2 moves from one end of the second screw 38 to the other. Afterwards, the extended ends of the bidirectional electric actuator 311 retract and separate from the screw block 310. Because the two extended ends of the bidirectional electric actuator 311 are equipped with second brake plates 313 via the connecting bracket 312, and the brake plates are in opposite directions, simply put, when the two extended ends of the bidirectional electric actuator 311 retract, the connecting bracket 312 moves to both sides, and the two second brake plates 313 respectively approach the corresponding receiving plate 11 and insert plate 12. The friction between the second brake plates 313 and the receiving plate 11 and insert plate 12 releases the friction, thus protecting the geological surface. The braking of the radar detection device 2 facilitates stability during the descent and approach to the ground test of the ground-penetrating radar detection device 2. At this time, the extended end of the bidirectional electric push rod 311 separates from the screw block 310. Therefore, the sliding frame 37 can be driven to slide along the inner side of the buckle frame 32 by the traction of the pull rope 19. At the same time, the second screw 38 rotates to reset the screw block 310. The moving distance of the sliding frame 37 is the same as the moving distance of the ground-penetrating radar detection device 2. The screw block 310 also corresponds to one side of the bidirectional electric push rod 311 of the ground-penetrating radar detection device 2 again. In short, first, according to the length of the second screw 38, the ground-penetrating radar detection device 2 is moved by the same distance. Then, the pull rope 19 moves the sliding frame 37 by the same distance. After the screw block 310 is reset, it can be reconnected to the bidirectional electric push rod 311, which facilitates the subsequent movement of the ground-penetrating radar detection device 2. The cooperation between the sliding frame 37 and the buckle frame 32 is a common sliding groove connection structure, which is not shown in the drawings. The sliding frame 37 and the buckle frame 32 will not separate due to the individual movement of the sliding frame 37.

[0027] like Figure 7 , Figure 10 and Figure 11 As shown, in some embodiments, the infrared detection assembly 4 further includes: a mounting plate 43, a rotating shaft 42, a crash barrier 44, and an infrared sensor 45. The top of the spring telescopic plate 41 is provided with the mounting plate 43, and the bottom of the mounting plate 43 is provided with the rotating shaft 42. The extended end of the spring telescopic plate 41 is rotatably connected to the mounting plate 43 through the rotating shaft 42 and a torsion spring. Infrared sensors 45 are fixed at equal intervals on the top surface of the mounting plate 43, and crash barriers 44 are fixed on both sides of the mounting plate 43. A right-angle bracket 314 is fixed to the bottom of the screw block 310, and the right-angle bracket 314 extends out of the bottom of the slide rail. The right-angle bracket 314 is fixedly connected to the bottom of the spring telescopic plate 41.

[0028] Understandably, because the right-angle bracket 314 is fixedly connected to the bottom of the spring telescopic plate 41, after the bidirectional electric push rod 311 is inserted into the screw block 310, the motor drives the second screw 38 to rotate. Through the transmission belt 39, the two second screws 38 rotate synchronously. The screw block 310 and the second screw 38 are threaded together, which drives the right-angle bracket 314 to move along the inside of the slide frame 37. The spring telescopic plate 41 also moves synchronously. The infrared sensor 45 on the mounting plate 43 detects the tunnel wall. Because the tunnel wall is curved, the anti-collision plate 44 presses against the inner wall during this process. The telescopic nature of the spring telescopic plate 41 keeps the infrared sensor 45 at a certain distance from the wall for detection. At the same time, the anti-collision plate 44 protects the infrared sensor 45. The connection between the right-angle bracket 314 and the spring telescopic plate 41 can avoid interference from the mounting component 3 during movement.

[0029] Working principle: When using the device, after moving it to the designated location in the tunnel, the first electric push rod 17 drives the first brake plate 18 to descend and contact the tunnel surface, braking the device for easy detection. After retracting the first brake plate 18, the device can be moved by the vertical rod 13 and the unfolded storage plate 11 and insert plate 12 on the vertical rod 13. The pulleys 14 at the bottom of the side plate 1 facilitate the movement of the device along the ground. The storage plate 11 and insert plate 12 are unfolded, and the dimensions of the frame composed of the storage plate 11, insert plate 12, and side plate 1 are adjusted to match the width of the tunnel. The storage plate 11 and insert plate 12 are locked with bolts. The ground-penetrating radar detection device 2 is installed inside the mounting assembly 3. When the second motor 35 drives the first screw 34 to rotate, the moving frame 33 and the first screw 34... The threaded engagement moves along the interior of the vertical frame 31, thereby lowering the ground-penetrating radar detection device 2, bringing the detection end 21 close to the ground for detection. During this movement, the ground-penetrating radar detection device 2 is raised until it exceeds the top of the push plate 315. The two extended ends of the bidirectional electric push rod 311 are inserted into the insertion holes 317 of the screw block 310. The motor drives the transmission belt 39, causing the two second screws 38 to rotate synchronously. The screw block 310 and the second screws 38 move along the top of the sliding frame 37 through the threaded engagement. Because the bidirectional electric push rod 311 is inserted into the screw block 310, the ground-penetrating radar detection device 2 moves horizontally along with the mounting assembly 3, the distance of which is the length of the second screws 38. Since the top of the push plate 315 does not exceed the ground-penetrating radar... The bottom detection end 21 of the ground-penetrating radar detection device 2 is reached, so the movement of the ground-penetrating radar detection device 2 will not be interfered with by the push plate 315. Initially, the push plate 315 is at the front end of the ground-penetrating radar detection device 2. After the ground-penetrating radar detection device 2 moves with the rotation of the second screw 38, the push plate 315 is located at the rear end of the ground-penetrating radar detection device 2. At this time, the ground-penetrating radar detection device 2 can continue to descend without interference from the push plate 315 at the bottom, and the detection positions of the two sections of the ground-penetrating radar detection device 2 are adjacent, thereby performing segmented testing of the straight cross-section of the tunnel surface. After the ground-penetrating radar detection device 2 moves from one end of the second screw 38 to the other end, the extended end of the bidirectional electric push rod 311 retracts and separates from the screw block 310. Because the bidirectional electric push rod 311 Because the two extended ends are equipped with second brake plates 313 via connecting bracket 312, and the brake plates are in opposite directions, when the two extended ends of the bidirectional electric push rod 311 retract, the connecting bracket 312 moves to both sides, and the two second brake plates 313 respectively approach the corresponding storage plate 11 and insert plate 12. The friction between the second brake plates 313 and the storage plate 11 and insert plate 12 is released, thus braking the ground radar detection device 2, which facilitates the maintenance of stability when the ground radar detection device 2 is lowered close to the ground for testing. At this time, the extended ends of the bidirectional electric push rod 311 are separated from the screw block 310, so the sliding frame 37 can be driven to slide along the inner side of the buckle frame 32 by the traction of the pull rope 19. At the same time, the second screw 38 rotates to reset the screw block 310.The sliding frame 37 moves the same distance as the ground-penetrating radar detection device 2. The screw block 310 also re-aligns with one side of the bidirectional electric push rod 311 of the ground-penetrating radar detection device 2. First, based on the length of the second screw 38, the ground-penetrating radar detection device 2 is moved the same distance. Then, the pull rope 19 moves the sliding frame 37 separately by the same distance. After the screw block 310 is reset, it can be reconnected to the bidirectional electric push rod 311, facilitating subsequent movement of the ground-penetrating radar detection device 2. Because the right-angle bracket 314 is fixedly connected to the bottom of the spring telescopic plate 41, after the bidirectional electric push rod 311 is inserted into the screw block 310, the motor drives the second screw 38 to rotate. Driven by the transmission belt 39, the two second screws 38 rotate synchronously. The screw block 310 engages with the second screw 38, driving the right-angle frame 314 to move inside the slide frame 37. Simultaneously, the spring telescopic plate 41 also moves synchronously. The infrared sensor 45 on the mounting plate 43 detects the tunnel wall. Because the tunnel wall is curved, it contacts the inner wall through the anti-collision plate 44. The telescopic nature of the spring telescopic plate 41 keeps the infrared sensor 45 within a certain distance from the wall, while also protecting it. The connection between the right-angle frame 314 and the spring telescopic plate 41 prevents interference from the mounting assembly 3 during movement.
