[0002] Ultrafine nano high-strength and high-permeability grouting materials can be used for the reinforcement and repair of underground projects, such as tunnels, underground pipeline corridors, underground parking lots, etc. By injecting this material into the foundation, soil layer or cracks through grouting, it can effectively improve the bearing capacity, impermeability and crack resistance of underground structures and enhance the stability of the structure.

[0003] The patent with publication number CN222013902U relates to an indoor model test device for grouting in geotechnical engineering. The test device includes a base, a slurry mixing barrel pad, a slurry mixing barrel, a motor, a grouting pump, a grouting main pipe, a movable grouting pipe, a branch pipe, a model box, etc. The slurry is evenly grouted into the model box through the grouting orifice by the branch pipe, which is used to solve the problem that the existing grouting technology cannot intuitively observe the grouting effect of the model test, cannot be evenly injected into the soil, and cannot achieve the effect of uniform addition. The advantages of this patent are: the overall device is easy to operate and move, the movable grouting pipe provides convenient grouting position selection, and the test system can also perform repeated tests. The model experimental device can be disassembled and cleaned. The device can greatly reduce the economic cost of the test and shorten the time cost, and can better guide the grouting process in actual engineering. However, when the device is grouting through the grouting pipe, the slurry is likely to overflow due to the gap between the grouting pipe and the grouting hole, thereby affecting the test results. Therefore, a grouting test model device of ultrafine nano high-strength and high-permeability grouting material with a sensor is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to address the deficiencies in the above-mentioned prior art and provide a grouting test model device for ultrafine nano high-strength and high-permeability grouting material with a sensor.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: a grouting test model device of ultrafine nano high-strength and high-permeability grouting material with a sensor, comprising a bottom plate, the top of the bottom plate is fixedly connected to a tripod, the inner wall of the tripod is fixedly connected to a spiral conveying cylinder, the top of the bottom plate is fixedly connected to a support plate, the left side of the support plate is fixedly connected to a cylinder, the output end of the cylinder is fixedly connected to a semicircular plate, the inner wall of the semicircular plate is fixedly connected to a moving rod, the left side of the spiral conveying cylinder is fixedly connected to a discharge pipe, and the moving rod The circumferential surface of the screw conveying cylinder is fixedly connected with a pressure plate, the top of the spiral conveying cylinder is fixedly connected with a funnel, the inner wall of the funnel is fixedly connected with a fixed plate, the inner wall of the fixed plate is rotatably connected with a reciprocating screw, the circumferential surface of the reciprocating screw is fixedly connected with a rotating plate, a filling mechanism for secondary filling of overflowed slurry is provided on the left side of the pressure plate, an adjusting mechanism for adjusting the height is provided on the left side of the tripod, a stirring rod is fixedly connected to the inner wall of the rotating plate, and when a grouting test is required, a sensor provided inside the discharge pipe will be used to adjust the height of the slurry. The sensor can know the pressure of the slurry when it is injected so as to make a judgment. At the same time as grouting, the pressure plate can seal the injection port, thereby preventing the slurry from leaking from the injection point to the area that should not be contacted, ensuring that the grouting material can accurately enter the target position in the soil or rock layer, which is crucial to improving grouting efficiency and ensuring construction quality. The inner wall of the support plate is fixedly connected to the circumferential surface of the spiral conveying cylinder, and the inner wall of the tripod is slidably connected to the circumferential surface of the moving rod. The pressure plate is used to seal the injection hole to prevent slurry leakage. The inner wall of the pressure plate is slidably connected to the surface of the discharge pipe. The spiral conveying cylinder is used to transport ultrafine nano grouting. A motor is provided on the top of the fixed plate, and the top of the reciprocating screw is fixedly connected to the output end of the motor. Before the injection work is carried out, the ultrafine nano slurry inside it can be mixed to ensure the uniformity and stability of the slurry, avoid particle precipitation and ensure uniform distribution of nanoparticles, thereby improving the performance of the slurry. At the same time, it can also effectively reduce the generation of bubbles and prevent the slurry from separating or decreasing in fluidity during the grouting process.

[0006] Preferably, the filling mechanism includes a fixed shell, which is fixedly connected to the left side of the pressure plate, the circumferential surface of the fixed shell is fixedly connected with a chamfered block 1, the inner wall of the chamfered block 1 is fixedly connected with an elastic telescopic rod, the circumferential surface of the fixed shell is sleeved with a sealing shell, the top of the sealing shell is fixedly connected with a chamfered block 2, the circumferential surface of the reciprocating screw rod is movably connected with a lifting plate, the inner wall of the lifting plate is fixedly connected with a fixed rod, the circumferential surface of the fixed rod is fixedly connected with a push plate, the circumferential surface of the stirring rod is fixedly connected with a scraper, and the inner wall of the funnel is fixedly connected with a limiting rod.

The slurry can be kept away from the inner wall of the lifting plate, and the slurry can be kept away from the inner wall of the lifting plate, so as to avoid the waste of slurry, and the test data can be further improved to avoid the test failure caused by slurry overflow.

The left side of the scraper is in contact with the inner wall of the funnel. In the process of processing the slurry, the slurry residue on its inner wall can be prevented from solidifying, resulting in excessive accumulation of slurry, thereby blocking the slurry outlet and affecting the normal operation of the device, and preventing the slurry from remaining on the inner wall of the funnel, thereby preventing the old slurry from mixing with the new slurry, resulting in uneven mixing, affecting the performance and fluidity of the slurry, and cleaning the residual slurry can avoid errors and ensure the authenticity and accuracy of the experimental data.

When sealing is performed, the surface of the straight plate generates an impact force to cause it to vibrate, and then the vibration is transmitted to the discharge pipe, thereby effectively preventing the slurry from accumulating at the slurry outlet and avoiding the slurry outlet from being blocked due to the viscosity of the slurry or the deposition of particulate matter. The plug promotes the flow of the slurry, makes the slurry flow out more evenly, and ensures the smooth progress of grouting. The inner wall of the connecting rod is threadedly connected to the circumferential surface of the threaded rod, and the circumferential surface of the connecting rod is slidingly connected to the inner wall of the bottom plate. The circumferential surface of the rotating wheel contacts the top of the straight plate. The adjusting plate will be used to adjust the height of the discharge pipe to adapt to different injection ports. When sealing, the surface of the straight plate generates an impact force to cause it to vibrate, and then the vibration will be transmitted to the discharge pipe, which can effectively prevent the slurry from accumulating at the discharge port, avoid the discharge port being blocked due to the viscosity of the slurry or the deposition of particulate matter, and then promote the flow of the slurry, make the slurry flow out more evenly, and ensure the smooth progress of grouting.

At the same time of grouting, the pressure plate can seal the injection port, thereby preventing the slurry from leaking from the injection point to the area that should not be contacted, ensuring that the grouting material can accurately enter the target position in the soil or rock layer, which is very important for improving grouting efficiency and ensuring construction quality. Before the injection work is carried out, the ultrafine nano slurry inside it can be mixed to ensure the uniformity and stability of the slurry, avoid particle precipitation and ensure the uniform distribution of nanoparticles, thereby improving the performance of the slurry, and at the same time effectively reduce the generation of bubbles, and prevent the slurry from separating or decreasing in fluidity during the grouting process.

[0009] 2. The grouting test model device of the ultrafine nano high-strength and high-permeability grouting material with a sensor, through the coordinated operation among the chamfered block, the elastic telescopic rod, the sealing shell and the fixed shell, when grouting, the movement of the chamfered block will drive the elastic telescopic rod to compress, thereby compressing the internal space of the sealing shell, so that the slurry flowing out of the sealing shell is squeezed into the hole again by the extrusion force of the fixed shell, thereby avoiding the waste of slurry, and further improving the test data, avoiding the situation where the test failure is caused by slurry overflow.

[0010] 3. The grouting test model device of the ultrafine nano high-strength and high-permeability grouting material with a sensor can prevent the slurry from remaining on the inner wall and solidifying during the slurry processing process through the coordinated operation between the chamfered block 2, the lifting plate, the fixed rod, the push plate, the scraper, and the limit rod, resulting in excessive accumulation of slurry, which in turn blocks the slurry outlet and affects the normal operation of the device, and prevents the slurry from remaining on the inner wall of the funnel, thereby preventing the old slurry from mixing with the new slurry, resulting in uneven mixing and affecting the performance and fluidity of the slurry.

[0011] 4. The grouting test model device of the ultrafine nano high-strength and high-permeability grouting material with a sensor operates in coordination with the sliding rod, rotating wheel, straight plate and protrusion. When sealing, the surface of the straight plate generates impact force to cause it to vibrate, and then transmits the vibration to the feed pipe, thereby effectively preventing the slurry from accumulating at the slurry outlet, avoiding the slurry outlet from being blocked due to the viscosity of the slurry or the deposition of particulate matter, and then promoting the flow of the slurry, making the slurry flow out more evenly, and ensuring smooth grouting.

[0012] 5. The grouting test model device of the ultrafine nano high-strength and high-permeability grouting material with a sensor operates in coordination with the threaded rod, the connecting block, the adjusting plate, and the connecting rod. When the height of the grouting port is too high, the upward movement of the connecting block will push the tripod upward, thereby pushing the discharge pipe upward, so that the height of the discharge pipe can be adjusted according to the holes of different heights, so that it can adapt to injection molding work in different situations, thereby increasing the diversity of the use of the device.

At the same time, the pressure of the slurry when injected is known through the sensor provided inside the discharge pipe 8 so as to be able to make a judgment. While grouting, the cylinder 5 is started and drives the semicircular plate 6 to move to the left. The movement of the semicircular plate 6 to the left drives the moving rod 7 to move to the left. The movement of the moving rod 7 to the left drives the pressing plate 9 to move, thereby enabling the pressing plate 9 to seal the injection port, thereby preventing the slurry from leaking from the injection point to the area that should not be contacted, and ensuring that the grouting material can accurately enter the target position in the soil or rock layer, which is crucial to improving the grouting efficiency and ensuring the construction quality. The inner wall of the support plate 4 is fixedly connected to the circumferential surface of the spiral conveying cylinder 3, the inner wall of the tripod 2 is slidably connected to the circumferential surface of the moving rod 7, the pressing plate 9 is used to seal the injection hole to prevent slurry leakage, the inner wall of the pressing plate 9 is slidably connected to the surface of the discharge pipe 8, the spiral conveying cylinder 3 is used to transport ultrafine nano-slurry, and a motor is provided on the top of the fixed plate 11, and the top of the reciprocating screw 12 is fixedly connected to the output end of the motor; Before the injection molding work is carried out, the ultrafine nano injection molding slurry will be inside the funnel 10. At this time, the electric start will drive the reciprocating screw 12 to rotate. The rotation of the reciprocating screw 12 drives the rotating plate 13 to rotate. The rotation of the rotating plate 13 drives the stirring rod 14 to rotate, so that the ultrafine nano slurry inside it can be mixed, thereby ensuring the uniformity and stability of the slurry, avoiding particle precipitation and ensuring uniform distribution of nanoparticles, thereby improving the performance of the slurry. At the same time, it can also effectively reduce the generation of bubbles and prevent the slurry from separating or decreasing in fluidity during the grouting process.

[0017] Working principle: When a grouting test is required, the device is moved to the designated position, and the discharge pipe 8 is aligned with the inside of the injection port. At this time, the spiral conveyor cylinder 3 is started to inject the prepared ultrafine nano slurry into the inside of the test hole. The semicircular plate 6 moves to the left, which drives the moving rod 7 to move to the left. The movement of the moving rod 7 to the left drives the pressure plate 9 to move, so that the pressure plate 9 can seal the injection port. Before the injection work is carried out, the ultrafine nano injection slurry will be inside the funnel 10. At this time, the electric start will drive the reciprocating screw 12 to rotate, and the rotation of the reciprocating screw 12 drives the rotating plate 13 to rotate. The rotation of the rotating plate 13 drives the stirring rod 14 to rotate, so that the ultrafine nano slurry inside it can be mixed, thereby ensuring the uniformity and stability of the slurry.

[0018] See also Figure 1-Figure 7On the basis of the above embodiment, in another embodiment of the present invention, the filling mechanism 15 includes a fixed shell 159, which is fixedly connected to the left side of the pressure plate 9, and the circumferential surface of the fixed shell 159 is fixedly connected to the chamfered block 151, and the inner wall of the chamfered block 151 is fixedly connected to the elastic telescopic rod 152. The circumferential surface of the fixed shell 159 is sleeved with a sealing shell 153, and the top of the sealing shell 153 is fixedly connected to the chamfered block 2 154. The circumferential surface of the reciprocating screw 12 is movably connected to the lifting plate 155, and the inner wall of the lifting plate 155 is fixedly connected to the fixing rod 156. The circumferential surface of the fixing rod 156 is fixedly connected to the push plate 157. The circumferential surface of the stirring rod 14 is fixedly connected to the scraper 158, and the inner wall of the funnel 10 is fixedly connected to the limiting rod 1510. During grouting, the movement of the pressing plate 9 drives the fixed shell 159 to move to the left, and the movement of the fixed shell 159 drives the sealing shell 153 to move. When the sealing shell 153 moves to the injection port, the sealing shell 153 will close the injection port, thereby preventing the slurry from flowing out. When the slurry flows out from the inside of the hole, the sensor inside the pressing plate 9 will activate the cylinder 5 through an electrical signal to drive the fixed shell 159 to continue moving to the left. The movement of the fixed shell 159 drives the chamfered block 151 to move to the left. The movement of the chamfered block 151 will drive the elastic telescopic rod 152 to be compressed, thereby compressing the internal space of the sealing shell 153, so that the slurry flowing out of the sealing shell 153 is squeezed into the hole again by the extrusion force of the fixed shell 159, thereby avoiding the waste of slurry, and further improving the test data to avoid the situation where the test failure is caused by slurry overflow; The circumferential surface of the elastic telescopic rod 152 is fixedly connected to the inner wall of the second chamfered block 154. The circumferential surface of the limiting rod 1510 is slidably connected to the inner wall of the lifting plate 155. The limiting rod 1510 is used to limit the lifting plate 155 so that it can only slide. The left side of the scraper 158 is in contact with the inner wall of the funnel 10. In the process of processing the slurry, the reciprocating screw 12 rotates through the reciprocating spiral groove starting from the surface to drive the lifting plate 155 to move up and down. The downward movement of the lifting plate 155 will drive the fixed rod 156 to move downward, and the downward movement of the fixed rod 156 will drive the push plate 157 to move downward. During the downward movement of the push plate 157, it will contact the outflow port of the slurry on the inner wall of the funnel 10, thereby preventing the slurry residue from solidifying on its inner wall, causing the slurry to gradually accumulate too much, and then blocking the slurry outlet and affecting the normal operation of the device. When the stirring rod 14 rotates, it will drive the scraper 158 to rotate. When the scraper 158 rotates, it will scrape off the slurry remaining on the inner wall of the funnel 10, thereby preventing the slurry from remaining on the inner wall of the funnel 10, thereby preventing the old slurry from mixing with the new slurry, resulting in uneven mixing, affecting the performance and fluidity of the slurry, and at the same time, cleaning the residual slurry can avoid errors and ensure the authenticity and accuracy of the experimental data.

[0019] Working principle: During grouting, the movement of the pressure plate 9 drives the fixed shell 159 to move to the left, the movement of the fixed shell 159 drives the sealing shell 153 to move, the movement of the fixed shell 159 drives the chamfered block 151 to move to the left, and the movement of the chamfered block 151 will drive the elastic telescopic rod 152 to be compressed, thereby compressing the internal space of the sealing shell 153, so that the slurry flowing out of the sealing shell 153 is squeezed into the hole again by the extrusion force of the fixed shell 159. In the process of processing the slurry, the reciprocating screw 12 rotates through the reciprocating spiral groove starting from the surface, driving the lifting plate 155 to move back and forth up and down, thereby blocking the slurry outlet and affecting the normal operation of the device. When the stirring rod 14 rotates, it will drive the scraper 158 to rotate, and when the scraper 158 rotates, it will scrape off the slurry remaining on the inner wall of the funnel 10.

[0020] The adjustment mechanism 16 includes a sliding rod 161, which is slidably connected to the inner wall of the fixed shell 159 via a spring. The inner wall of the sliding rod 161 is rotatably connected to a rotating wheel 162. The circumferential surface of the discharge pipe 8 is fixedly connected to a straight plate 163, the top of the straight plate 163 is fixedly connected to a protrusion 164, the inner wall of the bottom plate 1 is rotatably connected to a threaded rod 165, the inner wall of the tripod 2 is fixedly connected to a connecting block 166, the inner wall of the connecting block 166 is rotatably connected to an adjustment plate 167, and the inner wall of the adjustment plate 167 is rotatably connected to a connecting rod 168. When sealing, the fixed shell 159 moves to the left, which drives the sliding rod 161 to move. The movement of the sliding rod 161 drives the rotating wheel 162 to move. When the rotating wheel 162 moves, it contacts the protrusion 164 and is subjected to the reverse extrusion force of the protrusion 164, forcing the rotating wheel 162 to move upward. When the rotating wheel 162 moves upward, it compresses its own spring. When the rotating wheel 162 passes over the protrusion 164, the sliding rod 161 drives the rotating wheel 162 downward by the elastic force of the spring, thereby generating an impact force on the surface of the straight plate 163 to cause it to vibrate, and then transmits the vibration to the feed pipe 8, thereby effectively preventing the slurry from accumulating at the slurry outlet and avoiding the slurry outlet from being blocked due to the viscosity of the slurry or the deposition of particulate matter, thereby promoting the flow of the slurry, making the slurry flow out more evenly, and ensuring the smooth progress of the grouting; The inner wall of the connecting rod 168 is threadedly connected to the circumferential surface of the threaded rod 165. The circumferential surface of the connecting rod 168 is slidably connected to the inner wall of the bottom plate 1. The circumferential surface of the rotating wheel 162 is in contact with the top of the straight plate 163. The adjustment plate 167 is used to adjust the height of the discharge pipe 8 to adapt to different injection ports. When the height of the grouting port is too high, the threaded rod 165 is driven to rotate by manually turning the hand wheel. The threaded rod 165 rotates through the threaded groove on the surface to drive the connecting rod 168 to move to the right. When the connecting rod 168 moves to the right, it drives the adjusting plate 167 to rotate. When the adjusting plate 167 rotates, it generates an upward thrust on the connecting block 166 and pushes the connecting block 166 to move upward. The upward movement of the connecting block 166 pushes the tripod 2 to move upward, thereby pushing the discharge pipe 8 to move upward, so that the height of the discharge pipe 8 can be adjusted according to holes of different heights, so that it can adapt to injection molding work in different situations, so as to improve the diversity of the use of the device.

[0021] Working principle: When sealing, the fixed shell 159 moves to the left, which will drive the sliding rod 161 to move. The movement of the sliding rod 161 will drive the rotating wheel 162 to move. When the rotating wheel 162 moves, it will contact the protrusion 164 and will be subjected to the reverse extrusion force of the protrusion 164, forcing the rotating wheel 162 to move upward, thereby effectively preventing the slurry from accumulating at the slurry outlet. When the height of the grouting outlet is too high, the threaded rod 165 is rotated by manually turning the handwheel. The threaded rod 165 rotates through the threaded groove on the surface to drive the connecting rod 168 to move to the right, thereby pushing the discharge pipe 8 to move upward, so that the height of the discharge pipe 8 can be adjusted according to holes of different heights, so that it can adapt to injection molding work in different situations, so as to improve the diversity of the use of the device.
