Description

Technical Field

[0001] This invention belongs to the field of underground engineering geological disaster prevention and control, and relates to a device for simulating the grouting effect of underground engineering geological disasters. Background Technology

[0002] Underground engineering projects often encounter geological hazards such as karst water inrush and tunnel collapses during construction, which seriously affect project safety and progress. Grouting is a primary prevention and control method, but its effectiveness is influenced by multiple factors, including the characteristics of the grout, the characteristics of the injection medium, and construction parameters.

[0003] However, current predictions and evaluations of grouting effects largely rely on empirical summaries and lack systematic simulation experimental methods. Patent CN 115629186 B ​​discloses an underground high-pressure environment grouting simulation test device. It simulates underground high-pressure dynamic water environments under different pressures by using a pressure regulating valve located at the outlet. Different grouting holes are selected to simulate the grouting effect under different combinations of grouting holes. The grouting effect under different combinations of grouting holes is studied and predicted. After the grout solidifies, the solidified block inside the device needs to be removed for a series of testing experiments. However, the device is fixed by multiple bolts, making disassembly troublesome and wasting a lot of time. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a grouting effect simulation device for underground engineering geological disasters, and to solve the above-mentioned problems in the existing technology.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A device for simulating the grouting effect of underground engineering geological disasters includes a base, a rectangular frame, splicing components, a sealing cover, a support frame, an electric push rod, a fixing component, an inspection component, an impact component, and an anti-blocking component;

[0007] A rectangular frame is fixedly installed on the base, and a quick-assembly and disassembly splicing component is inserted into the rectangular frame. The splicing component and the sealing cover on top together form a grouting box. The sealing cover is equipped with a grouting pipe for grouting.

[0008] The support frame is fixed on the base and is erected on the left and right sides and above the grouting box; the electric push rod is set on the support frame and located directly above the sealing cover, so as to apply downward force to make the sealing cover tightly cover the top of the splicing assembly.

[0009] The fixing component is mounted on the base and located on the front and rear sides of the grouting box and can be connected to the splicing component to stabilize the splicing component on the rectangular frame and prevent it from shaking during the grouting process.

[0010] One end of the inspection component is connected to the fixing component and the other end can be inserted into the splicing component to inspect whether the splicing components are properly spliced ​​and to ensure that the splicing components are securely connected.

[0011] The impact components are installed on both sides of the support frame and located on the left and right sides of the grouting box so that they can impact the splicing components of the grouting box, making it easy to separate the cement blocks inside the grouting box from the splicing components.

[0012] The anti-clogging component is located at the air inlet on the sealing cover, and is used to inflate the grouting box with air and prevent gas leakage and mud blockage of the air inlet.

[0013] The present invention also includes the following technical features:

[0014] Specifically, the splicing assembly includes two front-to-back first side plates and two left-to-right second side plates, and the square first and second side plates can be spliced ​​together to form a square cavity;

[0015] The inner wall of the first side plate is provided with a vertical guide groove near the left and right edges, and a slot is provided at the top and bottom of the guide groove. The front and rear ends of the second side plate are provided with storage grooves at the top and bottom. When the second side plate is inserted between the two first side plates, the storage groove and the slot are opposite each other.

[0016] The storage slot is equipped with a first spring, one end of which is fixed to the inner wall of the storage slot, and the other end is connected to a trapezoidal block. The first spring can drive the trapezoidal block to extend and retract in the storage slot along the front and back direction. When the second side plate is tightly attached to the guide groove from top to bottom and inserted between the two first side plates, the trapezoidal block on the second side plate can first retract and then extend to insert into the slot on the first side plate to realize the quick snap-fit ​​between the first side plate and the second side plate.

[0017] Specifically, the outer wall of the second side plate is provided with four horizontal through slots near the four corners, and the horizontal through slots correspond one-to-one with the four storage slots and are connected; a slider is provided at the horizontal through slot and the slider is connected to the trapezoidal block, and the slider can move back and forth along the horizontal through slot with the trapezoidal block.

[0018] Specifically, the second side plate is provided with vertical connecting rods. Each second side plate has two connecting rods. Each connecting rod connects the slider at the top of the second side plate and the slider directly below it. Pulling the two connecting rods closer to each other can move the slider and the trapezoidal block, and can make the trapezoidal block disengage from the slot on the first side plate, thereby releasing the engagement between the first side plate and the second side plate.

[0019] Specifically, there are two sets of fixing components, located next to the two first side walls respectively; the fixing components include a fixing block fixed to the outer wall of the first side plate, and also include a rotating sleeve, a gear, a rack, a moving rod, a C-shaped sleeve, a rectangular rod, a magnet, a first toothed ring, and a second toothed ring;

[0020] The rotating sleeve is mounted on the base, and the gear is fixedly sleeved on the outside of the rotating sleeve. The gear meshes with two horizontal racks in front and behind it. The two racks are respectively connected to vertical moving rods. The bottom of the moving rods is located in a sliding groove on the base, and the upper end of the moving rods is connected to a C-shaped sleeve. The openings of the two C-shaped sleeves are opposite each other and symmetrically located on both sides of the fixed block. Rotating the rotating sleeve and the gear can drive the two racks and their connected moving rods to move closer to each other, thereby bringing the two C-shaped sleeves closer together and clamping them on the fixed block to fix the fixed block and the first side plate.

[0021] Specifically, a rectangular rod is installed inside the rotating sleeve, with the top of the rectangular rod extending beyond the top of the rotating sleeve; a magnet is fixed at the bottom of the rectangular rod, which can attract each other to the bottom of the rotating sleeve; a first toothed ring is connected to the lower part of the rectangular rod, and a second toothed ring is arranged below the first toothed ring, which can mesh with the second toothed ring, and the second toothed ring is fixed on the base; after the rectangular rod is moved upward to separate the first toothed ring and the second toothed ring, the rotating sleeve can rotate; when the rectangular rod and the rotating sleeve are attracted by the magnet, the first toothed ring and the second toothed ring mesh, thereby fixing the rotating sleeve.

[0022] The first and second toothed rings are concentrically arranged around the rotating sleeve. The rotating sleeve has symmetrical vertical slots on its sidewalls. The rectangular rod is fixed to the first toothed ring on both sides by connecting plates that pass through the vertical slots, and the connecting plates can move vertically along the vertical slots.

[0023] Specifically, the inspection component includes an L-shaped rod, with two L-shaped rods symmetrically arranged on both sides of each fixed component; one end of the L-shaped rod is connected to a moving rod, and the other end is provided with an insertion rod; the L-shaped rod can move left and right with the moving rod, and the direction of the insertion rod is along the left and right direction; a first slot is provided on the trapezoidal block located at the lower part, and a second slot is provided at the lower part of the second side plate; when the trapezoidal block is inserted into the slot on the first side plate, the second slot and the first slot are coaxially connected and the connection direction is left and right, and the insertion rod is compatible with the first slot and the second slot.

[0024] Specifically, there are two sets of impact components, which are respectively located next to the two second side plates; the impact components include two impact plates fixed to the outer wall of the second side plates, and also include a sliding sleeve, a rotating shaft, a pressing rod, an L-shaped support plate, an impact rod, a second spring, a driving block, and a rubber ball;

[0025] The sliding sleeve is installed through the side plate of the support frame, and a slide bar perpendicular to the side plate of the support frame is provided on the outer wall of the sliding sleeve. The rotating shaft is rotatably installed inside the sliding sleeve and both ends extend out of the sliding sleeve.

[0026] The end of the rotating shaft near the second side plate is fixedly connected to an extrusion rod, and two extrusion rods are symmetrically arranged on both sides of the rotating shaft; the end of the rotating shaft away from the second side plate is provided with a handle.

[0027] The sliding sleeve is fixedly connected to an L-shaped support plate at one end near the second side plate. Two L-shaped support plates are symmetrically arranged on both sides of the sliding sleeve. An impact rod is connected through the horizontal plate of each L-shaped support plate. The impact rod is perpendicular to the rotating shaft and can move axially. A second spring and a driving block are sleeved on the impact rod. The second spring and the driving block are located on both sides of the horizontal plate of the L-shaped support plate. A rubber ball is provided at the end of the impact rod, and the second spring is limited between the rubber ball and the L-shaped support plate.

[0028] When the extrusion rod rotates with the shaft, it can actuate the drive block to move the impact rod axially to compress the second spring. When the extrusion rod stops compressing, the second spring is released instantly, pushing the impact rod and the rubber ball to impact the impact plate, causing the impact plate and splicing components to vibrate.

[0029] Specifically, the impact assembly also includes a limiting assembly, which includes a storage sleeve fixed to one side of the support frame and a fixing hole opened on the slide bar; a fixing spring is provided inside the storage sleeve, one end of the fixing spring is connected to one end of a fixing rod, and the other end of the fixing rod is adapted to the fixing hole.

[0030] Specifically, the anti-clogging component includes an air inlet pipe located at the air inlet on the sealing cover, telescopic rods located on both sides of the air inlet pipe and perpendicularly penetrating the sealing cover, a return spring fitted on the telescopic rod, and a sealing plate vertically connected to the end of the telescopic rod and located in the sealing groove on the bottom surface of the sealing cover; the return spring is limited between the upper limiting end of the telescopic rod and the upper surface of the sealing cover; the sealing plate is opposite to the air inlet and can block the air inlet after air intake under the action of the telescopic rod and the return spring.

[0031] Compared with the prior art, the present invention has the following technical effects:

[0032] 1. By setting up a splicing component, the present invention enables the trapezoidal block to be inserted into the slot when the first side plate and the second side plate are interlocked, so that the first side plate and the second side plate form a rectangular frame, thereby enabling the first side plate and the second side plate to be quickly connected. When it is necessary to remove the cement block inside the device for testing, the time for disassembling the device to remove the cement block can be reduced, the workload of the staff can be reduced, and the work efficiency can be improved.

[0033] 2. By setting a fixing component, the first toothed ring and the second toothed ring are meshed with each other to fix the rotating sleeve, thereby preventing the rotating sleeve from being rotated accidentally and avoiding subsequent accidental rotation of the rotating sleeve. This further improves the stability of the second side plate and the first side plate, enhances the stability of the device during grouting, avoids gaps between the first and second side plates and the rectangular frame, reduces adverse factors affecting grouting, and effectively ensures the most realistic simulation environment.

[0034] 3. By setting up an inspection component, the present invention fixes the trapezoidal block when the insertion rod is inserted into the interior of the trapezoidal block, so that the connecting rod cannot drive the trapezoidal block to move through the slider. This not only further improves the reliability of the connection between the second side plate and the first side plate, but also checks whether the trapezoidal block has entered the interior of the slot, avoiding misalignment between the first side plate and the second side plate, effectively ensuring the reliability of the device, and avoiding misalignment between the first side plate and the second side plate and the rectangular frame caused by high internal grouting pressure.

[0035] 4. This invention, by setting up an impact component, pushes the impact rod and rubber ball to impact the impact plate, causing the impact plate to vibrate. The vibration can effectively separate the first and second side plates from the solidified cement block. The rotating shaft rotates continuously, and the impact rod continuously impacts the impact plate, so that the second and first side plates are fully separated from the cement block, greatly reducing the trouble caused when removing the cement block.

[0036] 5. By setting up an anti-blocking component, when the airflow to the inside of the air intake pipe is stopped, the sealing plate, under the push of the loss of airflow, is quickly reset by two return springs. Through two telescopic rods, the sealing plate is driven into the inside of the sealing groove to block the air intake pipe, ensuring that the gas inside the device will not leak and stabilizing the internal pressure of the device. At the same time, the rapid reset of the sealing plate can prevent mud from entering the inside of the air intake pipe and avoid blockage inside the air intake pipe. Attached Figure Description

Detailed Implementation

[0050] The following are specific embodiments of the present invention. It should be noted that the present invention is not limited to the following specific embodiments. All equivalent modifications made based on the technical solutions of this application fall within the protection scope of the present invention.

[0051] Example 1:

[0052] like Figures 1 to 11 As shown, this embodiment provides a grouting effect simulation device for underground engineering geological disasters, including a base 1, a rectangular frame 5, a splicing component 3, a sealing cover 10, a support frame 2, an electric push rod 6, a fixing component 33, an inspection component 39, an impact component 4, and an anti-blocking component 9.

[0053] A rectangular frame 5 is fixedly installed on the base 1. A quick-assembly and disassembly splicing component 3 is inserted into the rectangular frame 5. The splicing component 3 and the sealing cover 10 above it together form a grouting box. The sealing cover 10 is equipped with a grouting pipe 7 for grouting.

[0054] The support frame 2 is fixed on the base 1 and is mounted on the left and right sides and above the grouting box; the electric push rod 6 is mounted on the support frame 2 and located directly above the sealing cover 10, so as to apply downward force to make the sealing cover 10 tightly cover the top of the splicing assembly 3.

[0055] The fixing component 33 is mounted on the base 1 and located on the front and rear sides of the grouting box and can be connected to the splicing component 3 to stabilize the splicing component 3 on the rectangular frame 5 and prevent it from shaking during the grouting process.

[0056] The inspection component 39 is connected at one end to the fixing component 33 and the other end can be inserted into the splicing component 3 to check whether the splicing components 3 are spliced ​​in place and to ensure that the splicing components 3 are securely connected.

[0057] The impact component 4 is installed on both sides of the support frame 2 and located on the left and right sides of the grouting box so that it can impact the splicing component 3 of the grouting box, making it easy to separate the cement block in the grouting box from the splicing component 3.

[0058] The anti-clogging component 9 is located at the air inlet on the sealing cover 10. It is used to fill the grouting box with air and prevent gas leakage and mud blockage of the air inlet.

[0059] The splicing component 3 includes two front-to-back first side plates 31 and two left-to-right second side plates 32. The square first side plates 31 and second side plates 32 can be spliced ​​together to form a square cavity.

[0060] The inner wall of the first side plate 31 is provided with a vertical guide groove near the left and right edges. The guide groove is provided with a slot 311 at the top and bottom. The front and rear ends of the second side plate 32 are provided with storage slots 34 at the top and bottom. When the second side plate 32 is inserted between the two first side plates 31, the storage slots 34 and the slots 311 are opposite each other.

[0061] The storage slot 34 is equipped with a first spring 310, one end of which is fixed to the inner wall of the storage slot 34, and the other end is connected to a trapezoidal block 35. The first spring 310 can drive the trapezoidal block 35 to extend and retract in the storage slot 34 in the front-back direction. When the second side plate 32 is tightly attached to the guide groove from top to bottom and inserted between the two first side plates 31, the trapezoidal block 35 on the second side plate 32 can first retract and then extend to insert into the slot 311 on the first side plate 31 to realize the quick engagement of the first side plate 31 and the second side plate 32.

[0062] The outer wall of the second side plate 32 is provided with four horizontal through grooves 37 near the four corners, and the horizontal through grooves 37 correspond one-to-one with the four storage grooves 34 and are connected; a slider 38 is provided at the horizontal through groove 37 and the slider 38 is connected to the trapezoidal block 35, and the slider 38 can move back and forth along the horizontal through groove 37 with the trapezoidal block 35.

[0063] The second side plate 32 is provided with vertical connecting rods 36. Each second side plate 32 corresponds to two connecting rods 36. Each connecting rod 36 connects the upper slider 38 and the slider 38 directly below the four sliders 38 at the four corners of the second side plate 32. Pulling the two connecting rods 36 closer together can move the sliders 38 and the trapezoidal block 35, and can make the trapezoidal block 35 disengage from the slot 311 on the first side plate 31, thereby releasing the first side plate 31 from the second side plate 32.

[0064] During the grouting experiment, two first side plates 31 are placed vertically on opposite sides inside the rectangular frame 5. Two second side plates 32 are then inserted into the guide grooves on the first side plates 31. The second side plates 32 move the trapezoidal block 35 towards the first side plates 31, causing the hypotenuse of the trapezoidal block 35 to contact the top of the first side plate 31, thus squeezing the trapezoidal block 35 into the receiving groove 34. When the trapezoidal block 35 moves to the slot 311, under the elastic force of the first spring 310, the trapezoidal block 35 is springed into place. Within the slot 311, the first side plate 31 and the second side plate 32 are quickly connected. When disassembly is required, the two connecting rods 36 are pushed closer to each other, and the trapezoidal block 35 is moved into the storage slot 34 by the slider 38, so that the trapezoidal block 35 is removed from the slot 311. The second side plate 32 can then be pulled out between the two first side plates 31 to complete the disassembly. When inspecting cement blocks inside the device, the time for disassembling the device to remove cement blocks can be reduced, the workload of the staff can be reduced, and the work efficiency can be improved.

[0065] There are two sets of fixing components 33, located next to the two first side walls respectively; the fixing components 33 include a fixing block 3312 fixed to the outer wall of the first side plate 31, and also include a rotating sleeve 337, a gear 335, a rack 334, a moving rod 333, a chamfered sleeve 332, a rectangular rod 336, a magnet 3311, a first toothed ring 339, and a second toothed ring 3310.

[0066] A rotating sleeve 337 is mounted on the base 1. A gear 335 is fixedly mounted on the outside of the rotating sleeve 337. The gear 335 meshes with two horizontal racks 334 at its front and rear. The two racks 334 are respectively connected to vertical moving rods 333. The bottom of the moving rods 333 is located in the left-right sliding grooves 331 on the base 1. The upper end of the moving rods 333 is connected to a chamfered sleeve 332. The two chamfered sleeves 332 have openings facing each other and are symmetrically arranged on both sides of the fixed block 3312. Rotating the rotating sleeve 337 and the gear 335 can drive the two racks 334 and their connected moving rods 333 to move closer to each other, thereby causing the two chamfered sleeves 332 to move closer and clamp onto the fixed block 3312 to fix the fixed block 3312 and the first side plate 31.

[0067] A rectangular rod 336 is installed inside the rotating sleeve 337, with the top of the rectangular rod 336 extending beyond the top of the rotating sleeve 337. A magnet 3311 is fixed at the bottom of the rectangular rod 336, and the magnet 3311 can attract each other to the inner bottom of the rotating sleeve 337. The lower part of the rectangular rod 336 is connected to a first toothed ring 339, and a second toothed ring 3310 is arranged below the first toothed ring 339. The first toothed ring 339 can engage with the second toothed ring 3310, and the second toothed ring 3310 is fixed on the base 1. After the rectangular rod 336 is moved upward to separate the first toothed ring 339 from the second toothed ring 3310, the rotating sleeve 337 can rotate. When the rectangular rod 336 and the rotating sleeve 337 are attracted by the magnet 3311, the first toothed ring 339 and the second toothed ring 3310 engage, thereby fixing the rotating sleeve 337.

[0068] The first toothed ring 339 and the second toothed ring 3310 are both arranged concentrically around the rotating sleeve. The rotating sleeve has symmetrical vertical through grooves 338 on its side wall. The rectangular rod 336 is fixed to the first toothed ring 339 on both sides through connecting plates that pass through the vertical through grooves 338, and the connecting plates can move vertically along the vertical through grooves 338.

[0069] After the first side plate 31 and the second side plate 32 are quickly connected, and the first side plate 31 and the second side plate 32 are only in a nested relationship with the rectangular frame 5, the high grouting pressure during grouting will cause the first side plate 31 and the second side plate 32 to shake as a whole, resulting in grout leakage. Therefore, after connecting the first side plate 31 and the second side plate 32, pulling the rectangular rod 336 upward will cause the first toothed ring 339 and the second toothed ring 3310 to separate from each other, releasing the fixation of the rotating sleeve 337. Rotating the rotating sleeve 337 will cause the rectangular rod 336 to rotate. The rectangular rod 336 will cause the two racks 334 to move closer to each other. The racks 334 will pull the moving rod 333 in the groove 331. The inner movement causes the two C-shaped sleeves 332 to move closer together and fit over the fixed block 3312. After the sleeves are fitted, the side plates cannot be pulled upwards and are firmly fixed inside the rectangular frame 5. The rectangular rod 336 is released, causing the magnet 3311 to attract the rotating sleeve 337, making the first toothed ring 339 and the second toothed ring 3310 mesh with each other, fixing the rotating sleeve 337. This prevents the rotating sleeve 337 from being accidentally rotated, avoids subsequent accidental rotation of the rotating sleeve 337, further improves the stability of the second side plate 32 and the first side plate 31, improves the stability of the device during grouting, reduces adverse factors affecting grouting, and effectively ensures the most realistic simulation environment.

[0070] The inspection component 39 includes an L-shaped rod 391, with two L-shaped rods 391 symmetrically arranged on both sides of each fixed component 33. One end of the L-shaped rod 391 is connected to the moving rod 333, and the other end is provided with a plug rod 392. The L-shaped rod 391 can move left and right with the moving rod 333, and the direction of the plug rod 392 is along the left and right direction. A first slot 393 is provided on the trapezoidal block 35 located at the lower part, and a second slot 394 is provided at the lower part of the second side plate 32. When the trapezoidal block 35 is inserted into the slot 311 on the first side plate 31, the second slot 394 and the first slot 393 are coaxially connected and the connection direction is left and right. The plug rod 392 is compatible with the first slot 393 and the second slot 394.

[0071] When the second side plate 32 is connected to the first side plate 31, the connecting rod 36 is exposed to the outside. Workers are prone to accidentally pushing the connecting rod 36, which can easily cause misalignment between the second side plate 32 and the first side plate 31, creating gaps between the components and affecting the grouting test results. Therefore, when the gear 335 rotates, the rack 334 drives the two moving rods 333 to move closer together. At this time, the fixing component 33 synchronously drives the L-shaped rods 391 to move closer together. The L-shaped rods 391 drive the two insert rods 392 to move closer together and insert them into the first slot 393 and the second slot 394 respectively, fixing the trapezoidal block 35 and allowing for inspection of the trapezoidal block 35. Whether the trapezoidal block 35 is fully inserted into the slot 311 is checked to prevent the trapezoidal block 35 from getting stuck inside the storage slot 34 and being unable to move. When the insertion rod 392 is inserted into the trapezoidal block 35, it can also fix the trapezoidal block 35, so that the connecting rod 36 cannot drive the trapezoidal block 35 to move through the slider 38. This not only further improves the reliability of the connection between the second side plate 32 and the first side plate 31, but also checks whether the trapezoidal block 35 is inserted into the slot 311, preventing the first side plate 31 and the second side plate 32 from being misaligned with each other, effectively ensuring the reliability of the device, and preventing misalignment between the first side plate 31 and the second side plate 32 and the rectangular frame 5 due to the high internal pressure of grouting.

[0072] Two sets of impact components 4 are respectively located beside the two second side plates 32. The impact components 4 include two impact plates 49 fixed to the outer wall of the second side plate 32, and also include a sliding sleeve 41, a rotating shaft 42, a pressing rod 410, an L-shaped support plate 48, an impact rod 45, a second spring 44, a driving block 46, and a rubber ball. The sliding sleeve 41 is installed through the side plate of the support frame 2. A slide bar 47 perpendicular to the side plate of the support frame 2 is provided on the outer wall of the sliding sleeve 41. The rotating shaft 42 is rotatably installed inside the sliding sleeve 41 and both ends extend out of the sliding sleeve 41. The end of the rotating shaft 42 near the second side plate 32 is fixedly connected to the pressing rod 410. The two pressing rods 410 are symmetrically arranged on both sides of the rotating shaft 42. The end of the rotating shaft 42 away from the second side plate 32 is provided with a handle. The end of the sliding sleeve 41 near the second side plate 32 is fixedly connected to the L-shaped support plate 48. Two L-shaped support plates 48 are symmetrically arranged on both sides of the sliding sleeve 41. An impact rod 45 is connected through the horizontal plate of each L-shaped support plate 48. The impact rod 45 is perpendicular to the rotating shaft 42 and can move axially. A second spring 44 and a driving block 46 are sleeved on the impact rod 45. The second spring 44 and the driving block 46 are respectively located on both sides of the horizontal plate of the L-shaped support plate 48. A rubber ball is provided at the end of the impact rod 45 and the second spring 44 is limited between the rubber ball and the L-shaped support plate 48. When the pressing rod 410 rotates with the rotating shaft 42, it can move the driving block 46 to drive the impact rod 45 to move axially to compress the second spring 44. When the pressing rod 410 stops pressing, the second spring 44 is released instantaneously, pushing the impact rod 45 and the rubber ball to impact the impact plate 49, causing the impact plate 49 and the splicing assembly 3 to vibrate.

[0073] The impact assembly 4 also includes a limiting assembly 43, which includes a storage sleeve 432 fixed to one side of the support frame 2 and a fixing hole 434 opened on the slide bar 47; a fixing spring 433 is provided inside the storage sleeve 432, one end of the fixing spring 433 is connected to one end of the fixing rod 431, and the other end of the fixing rod 431 is adapted to the fixing hole 434.

[0074] After grouting is completed and the internal grout has solidified, the cement blocks inside need to be removed. The solidified cement blocks tend to adhere to the inner walls of the first side plate 31 and the second side plate 32, making it difficult to remove them smoothly from the rectangular frame 5. At this point, the sliding sleeve 41 is pushed to move within the support frame 2, causing the L-shaped support plate 48 to move between the two impact plates 49. The rotating shaft 42 then rotates the two extrusion rods 410, whose lower surfaces contact the driving block 46. As the extrusion rods 410 continue to move, they press the driving block 46 towards the center of the rotating shaft 42. The impact rod 45 moves synchronously toward the center of the rotating shaft 42 to compress the second spring 44. When the compression rod 410 rotates away from the drive block 46, the drive block 46 loses compression, and the second spring 44 is released instantly, pushing the impact rod 45 and the rubber ball to impact the impact plate 49, causing the impact plate 49 to vibrate. The vibration can effectively separate the first side plate 31 and the second side plate 32 from the solidified cement block. The rotating shaft 42 continues to rotate, and the impact rod 45 continuously impacts the impact plate 49, so that the second side plate 32 and the first side plate 31 are fully separated from the cement block, greatly reducing the trouble caused when removing the cement block.

[0075] When the shaft 42 is rotated, due to the sliding between the sliding sleeve 41 and the support frame 2, a horizontal force will continuously push and pull the sliding sleeve 41 to move left and right inside the support frame 2 when the shaft 42 is rotated. This causes the impact rod 45 to move out between the two impact plates 49, resulting in an unsatisfactory impact effect. When the sliding sleeve 41 moves to the designated position, the fixing rod 431 is inserted into the fixing hole 434 to fix the slide bar 47, thereby fixing the sliding sleeve 41 inside the support frame 2, so that the shaft 42 can be rotated more stably in the future.

[0076] The anti-blocking component 9 includes an air inlet pipe 91 located at the air inlet on the sealing cover 10, a telescopic rod 94 located on both sides of the air inlet pipe 91 and perpendicularly penetrating the sealing cover 10, a return spring 95 fitted on the telescopic rod 94, and a sealing plate 93 vertically connected to the end of the telescopic rod 94 and located in the sealing groove 92 on the bottom surface of the sealing cover 10; the return spring 95 is limited between the upper limit end of the telescopic rod 94 and the upper surface of the sealing cover 10; the sealing plate 93 is opposite to the air inlet and can block the air inlet after air intake under the action of the telescopic rod 94 and the return spring 95.

[0077] Before conducting the grouting experiment, air needs to be injected into the device to increase the internal pressure and simulate the soil pressure. However, during grouting, slurry will enter the air inlet pipe 91. When the slurry dries, it will cause blockage inside the air inlet pipe 91. Therefore, when the air inlet pipe 91 is connected to an external compressed air tank, high-pressure air is supplied into the air inlet pipe 91. The air will push the sealing plate 93 downward, pull the two telescopic rods 94 to move, and simultaneously squeeze the return spring 95, causing the sealing plate 93 to move out of the sealing groove 92. The airflow in the inlet pipe 91 smoothly enters the interior of the device. When the required pressure is reached, the airflow to the interior of the inlet pipe 91 is stopped. Under the push of the deprivation of airflow, the two return springs 95 quickly return to their original positions. Through the two telescopic rods 94, the sealing plate 93 is driven into the interior of the sealing groove 92 to seal the inlet pipe 91, ensuring that the gas inside the device will not leak and stabilizing the internal pressure of the device. At the same time, the rapid return of the sealing plate 93 can prevent mud from entering the interior of the inlet pipe 91 and avoid blockage inside the inlet pipe 91.

[0078] In this embodiment, a contact frame 8 is fixedly connected to the upper surface of the sealing cover 10. By pushing the contact frame 8 with the electric push rod 6, the sealing cover 10 can be firmly fastened to the first side plate 31 and the second side plate 32.

[0079] Instructions for use: First, interlock the first side plate 31 and the second side plate 32. After interlocking, insert them into the rectangular frame 5 for fixation. Then, fasten the sealing cap 10 onto the first side plate 31 and the second side plate 32. Push the contact frame 8 using the electric push rod 6 to firmly fasten the sealing cap 10 onto the first side plate 31 and the second side plate 32. Next, rotate the gear 335, which, through the rack 334, drives the chain's various I-shaped sleeves 332 to fit onto the outside of the fixing block 3312, firmly fixing the first side plate 31 inside the rectangular frame 5. The first side plate 31 can be checked using the inspection component 39. The side plate 31 and the second side plate 32 are further fixed to further improve the stability of the device. Then, when disassembling the device, the first side plate 31 and the second side plate 32 and the cement block must be separated from each other beforehand. The rotating shaft 42 is driven through a series of transmissions, so that the two impact rods 45 continuously impact the impact plate 49, causing the first side plate 31 and the second side plate 32 to vibrate and quickly separate from the cement block. The sliding sleeve 41 can be fixed by the limiting component 43 to ensure the stable rotation of the rotating shaft 42, and the impact rods 45 continuously impact the impact plate 49.
