[0042] The upper end of the model box 10 forms an open end, and the model box 10 is used to bury the model pile 11. Sand, clay and other test soils can be used to bury the model column. The grouting mechanism 30 is used to inject slurry into the model box 10. The slurry can be cement slurry. The grouting mechanism 30 mixes the cement slurry and injects it into the model box 10 to fix the model pile 11. The model box 10 can be constructed as a polygonal box with an open upper end. For example, the model box 10 can have four side walls configured as a quadrilateral box, and the four side walls of the model box 10 The side walls can all be made of steel plates, and the four side walls of the model box 10 can be detachably connected. When it is necessary to bury the model pile 11 in the model box 10, the four side walls of the model box 10 are connected so that the four side walls of the model box 10 jointly define an installation cavity for installing the model pile 11. After the test is completed, the four side walls of the model box 10 can be disassembled, and the integrity and shape of the grouting slurry vein can be maintained to the greatest extent when the model pile 11 is taken out, so as to observe and measure the slurry diffusion morphology, slurry filling, and diffusion distribution after grouting.

[0049] The force-applying device 50 can be a device such as a winch, a crane, etc. As an example of the present application, the force-applying device 50 can be a winch, and the multifunctional model test device 100 can be provided with a control device, which can be a numerical control platform. The force-applying device 50 is connected to the control device in communication, and the force-applying device 50 can be electronically controlled and monitored in real time through the control device, so as to achieve the application of loads of different sizes, and the operation is simple and convenient. In the first state and the second state, the force-applying device 50 applies a downward force to the mounting beam 40, and the force-applying device 50 can be connected to an end of the mounting beam 40 away from the model pile 11, so that the force-applying device 50 applies a downward force to the mounting beam 40. By applying a downward force to the mounting beam 40 through the force-applying device 50, in the first state, through the lever principle, the mounting beam 40 abuts against the upper end surface of the model pile 11 to give the model pile 11 a vertical downward pressure, and the force-applying device 50 is controlled by the control device to change the force value to perform a vertical downward pressure test on the model pile 11. In the second state, the mounting beam 40 and the model pile 11 can be connected by a hinge, and the connection between the mounting beam 40 and the model pile 11 can give the model pile 11 a vertical upward tension, and the force-applying device 50 is controlled by the control device to change the force value to perform a vertical upward tension test on the model pile 11. In the third state, the force-applying device 50 and the model pile 11 can be connected by a traction rope, and a pulley is connected to the mounting beam 40, and the traction rope is passed through the pulley, so that the traction rope between the model pile 11 and the pulley extends in the horizontal direction, so that the force-applying device 50 is used to apply a horizontal force to the model pile 11 through the mounting beam 40, and the force-applying device 50 is controlled by the control device to change the force value to perform a horizontal tension test on the model pile 11. As a result, different types of accurate loads can be applied to the model pile 11 without frequent manual pressure supplementation or weight application, which reduces interference, greatly improves the accuracy of the load applied to the model pile 11 and the test efficiency, and the test device has a simple structure and low operation complexity, and a single person can perform the test operation.

In the second state, the mounting beam 40 and another support seat 20 can be hingedly connected and used to connect with the model pile 11. In the third state, the mounting beam 40 and both support seats 20 can be hingedly connected. In the first state and the second state, the force applying device 50 applies a downward force to the mounting beam 40. In the third state, the force applying device 50 is used to apply a horizontal force to the model pile 11 through the mounting beam 40. Different types of accurate numerical loads can be applied to the model pile 11 without frequent manual pressure replenishment or weight application, which reduces interference, greatly improves the accuracy of the load applied to the model pile 11 and the test efficiency, and can also flexibly perform loading tests on the model piles 11 at different positions in the model box 10, thereby improving the functionality of the test device. The test device has a simple structure and low operation complexity.

[0051] According to some embodiments of the present invention, Figure 1 As shown, the mounting beam 40 is movably disposed on the corresponding support seat 20 along the second direction, and the mounting beam 40 is selectively connected to the corresponding support seat 20 , and the first direction, the second direction and the height direction of the multifunctional model testing device 100 are perpendicular.

[0052] in, Figure 1 The X direction is the first direction, and the Y direction is the second direction.

[0055] The support portion 22 is formed with a guide groove 221 extending along the second direction, and the movable portion 23 is slidably arranged in the guide groove 221, providing a clear sliding path for the movable portion 23, and can prevent the movable portion 23 from deviating from the predetermined position during the sliding process, thereby improving the safety and reliability of the multifunctional model testing device 100. The movable portion 23 is used to be fixedly connected with the mounting beam 40, and the position of the movable portion 23 can be easily adjusted to meet the position requirement of the mounting beam 40. The movable portion 23 is selectively fixed to the support portion 22. When the mounting beam 40 and the movable portion 23 are adjusted, the movable portion 23 is fixed to the support portion 22, which can ensure the stability of the mounting beam 40 and the movable portion 23 during the test. Through the adjustment of the telescopic rod 21 and the sliding and fixing functions of the movable part 23, the height adjustment of the support part 22 can be easily achieved, and the rapid installation and disassembly between the model box 10 and the mounting beam 40 can be facilitated, saving installation time and labor costs, improving work efficiency, and enabling the mounting beam 40 to accurately abut or connect with the upper end surface of the model pile 11 that needs to be loaded.

[0056] According to some embodiments of the present invention, Figure 1 and Figure 2 As shown, the upper end of the guide groove 221 is open, and the guide groove 221 has a first side wall 222 and a second side wall 223 that are opposite and spaced apart along a first direction, the first side wall 222 is formed with a first mounting wall 224, and the second side wall 223 is formed with a second mounting wall 225, the first mounting wall 224 and the second mounting wall 225 are opposite and spaced apart, the moving part 23 has a moving part body 231 and a mounting ear 232, the side wall of the moving part body 231 is formed with a mounting ear 232, the mounting ear 232 is overlapped with the first side wall 222 and the second side wall 223, and the moving part body 231 is arranged between the first side wall 222 and the second side wall 223.

[0057] The upper end of the guide groove 221 is open so that the moving part 23 can be installed in the guide groove 221 from the upper end of the guide groove 221. The guide groove 221 has a first side wall 222 and a second side wall 223 that are opposite and spaced apart in a first direction. The first side wall 222 and the second side wall 223 define the width of the guide groove 221.

The first mounting wall 224 and the second mounting wall 225 are opposite and spaced apart. The moving part 23 has a moving part body 231. The side wall of the movable part body 231 is formed with a mounting ear 232, and the mounting ear 232 is overlapped on the first side wall 222 and the second side wall 223. The movable part body 231 is arranged between the first side wall 222 and the second side wall 223, so that the movable part body 231 can move in the guide groove 221, and the moving range of the movable part body 231 is limited by the first side wall 222 and the second side wall 223, so that the movable part body 231 can move stably in the guide groove 221, which is beneficial to improving the stability and reliability of the movable part 23.

The guide hole 226 of the first mounting wall 224 can penetrate the first mounting wall 224 along the height direction of the multifunctional model test device 100. The guide hole 226 of the second mounting wall 225 can penetrate the second mounting wall 225 along the height direction of the multifunctional model test device 100. The mounting ear 232 is formed with a mounting hole 233. The mounting hole 233 can penetrate the mounting ear 232 along the height direction of the multifunctional model test device 100. The mounting hole 233 and the guide hole 226 are arranged opposite to each other. Bolts can be inserted through the mounting hole 233 and the guide hole 226, and the displacement can be changed by adjusting the tightness of the bolts. The movable part 23 can be adjusted to meet different test requirements and improve the flexibility and accuracy of the test. When the movable part 23 needs to be disassembled, the bolts can be directly removed to remove the movable part 23 from the support seat 20 without complicated operations or damage to the original connection structure.

During the installation and debugging process, the tightness of the bolts can be easily adjusted as needed to accurately position and fix the moving part 23, which helps to speed up the progress of installation and debugging and improve work efficiency.

[0061] Furthermore, the connection part 42 of the above-mentioned mounting beam 40 can also be assembled with the mounting beam 40 in the same manner as the assembly method between the support seat 20 and the movable part 23, so as to accurately position and fix the connection part 42, which helps to speed up the progress of installation and debugging and improve work efficiency.

[0062] According to some embodiments of the present invention, the multifunctional model testing device 100 further includes: a calibration mechanism, which is selectively mounted on the mounting beam 40 and is used to emit a laser line toward the bottom of the multifunctional model testing device 100, and drives the calibration mechanism to move synchronously when the mounting beam 40 moves along the second direction.

[0063] The calibration mechanism can be constructed as a laser positioning structure, which uses the characteristics of lasers to determine the position and direction of the target object through the interaction between the emitted laser beam and the target object. The calibration mechanism is selectively installed on the mounting beam 40, and the calibration mechanism can be selectively installed on the connecting portion 42 of the mounting beam 40. When the calibration mechanism is installed on the connecting portion 42 of the mounting beam 40, the connecting portion 42 moves along the first direction to drive the calibration mechanism to move synchronously, and drives the calibration mechanism to move synchronously when the mounting beam 40 moves along the second direction. The calibration mechanism is used to emit a laser line toward the bottom of the multifunctional model test device 100, so that the laser line can be irradiated on the model pile 11. Through the adjustment of the calibration mechanism in the first direction and the second direction, the model pile 11 can be accurately positioned. This positioning method is not only highly accurate, but also easy to operate, greatly improving the efficiency and accuracy of the test, and can calibrate the verticality of the model pile 11, thereby avoiding test errors caused by tilt or offset of the model pile 11 during the embedding process.

[0064] According to some embodiments of the present invention, when the calibration mechanism is installed on the mounting beam 40, the calibration mechanism is adjustable relative to the mounting beam 40 along the first direction. Specifically, the calibration mechanism can be installed on the connecting portion 42 of the mounting beam 40, and the connecting portion 42 can move along the extension direction (first direction) of the mounting beam 40. The movement of the connecting portion 42 along the first direction can drive the calibration mechanism to move synchronously, so that the calibration mechanism is adjustable relative to the mounting beam 40 along the first direction. By adjusting the calibration mechanism in the first direction and the second direction, the model pile 11 can be accurately positioned. This positioning method is not only highly accurate, but also easy to operate, which greatly improves the efficiency and accuracy of the test, and can calibrate the verticality of the model pile 11, thereby avoiding test errors caused by tilt or offset of the model pile 11 during the embedding process.

[0065] According to some embodiments of the present invention, Figure 8 As shown, the mounting beam 40 has a mounting portion 41, and the mounting portion 41 is located on one side of another support seat 20 along the first direction. The force-applying device 50 is suitable for applying a downward force to the mounting beam 40 through the mounting portion 41, and the force-applying device 50 is also suitable for applying a horizontal force to the model pile 11 through the mounting portion 41.

[0066] The mounting beam 40 has a mounting portion 41, and the mounting portion 41 can be located on a side of the other support seat 20 away from the one support seat 20 along the first direction. The force applying device 50 is suitable for applying a downward force to the mounting beam 40 through the mounting portion 41, such as Figure 8As shown, when the mounting beam 40 is in the first state, the mounting beam 40 and a support seat 20 can be hingedly connected and used to abut against the upper end surface of the model pile 11, the force-applying device 50 and the mounting portion 41 can be connected by a traction rope, and the downward force applied by the force-applying device 50 to the mounting beam 40 through the mounting portion 41 can be transmitted to the model pile 11, which can be used to simulate the performance of the model pile 11 under the action of a vertical downward load.

[0067] like Fig. 9 As shown, when the mounting beam 40 is in the second state, the mounting beam 40 and another support seat 20 can be hingedly connected and used to connect with the model pile 11, the force-applying device 50 and the mounting portion 41 can be connected by a traction rope, and the downward force applied by the force-applying device 50 to the mounting beam 40 through the mounting portion 41 can be converted into a vertical upward pulling force on the model pile 11, which can be used to simulate the performance of the model pile 11 under the action of a vertical upward load.

[0068] like Fig.10 As shown, the force-applying device 50 is also suitable for applying a horizontal force to the model pile 11 through the mounting portion 41. When the mounting beam 40 is in the third state, the mounting beam 40 and the two support seats 20 can be hingedly connected, and the force-applying device 50 and the model pile 11 can be connected by a traction rope. The mounting portion 41 is connected to a pulley, and the traction rope is passed through the pulley so that the traction rope between the model pile 11 and the pulley extends in the horizontal direction, so that the force-applying device 50 is used to apply a horizontal force to the model pile 11 through the mounting portion 41, which can be used to simulate the performance of the model pile 11 under the action of a horizontal load.

[0069] The design of the mounting beam 40 and the force applying device 50 enables the tester to precisely control the force and direction applied to the model pile 11. This helps to improve the accuracy and reliability of the test, making the test results closer to the actual engineering situation. The adjustability of the mounting beam 40 and the force applying device 50 enables the tester to perform a variety of different test settings as needed. For example, the height and position of the mounting beam 40 can be adjusted, and the force and direction applied to the model pile 11 can be changed. This flexibility enables the test to adapt to different research needs and engineering backgrounds.

[0070] According to some embodiments of the present invention, Figure 5 and Figure 6 As shown, the grouting mechanism 30 includes: a slurry preparation body 31 and a grouting pipe 32. The grouting pipe 32 is connected to the slurry preparation body 31. The grouting pipe 32 is selectively assembled in the model box 10. When the grouting pipe 32 is assembled in the model box 10, the slurry preparation body 31 is used to inject slurry into the model box 10 through the grouting pipe 32.

[0071] Among them, the slurry preparation body 31 is used to prepare slurry that meets the requirements, the grouting pipe 32 is connected to the slurry preparation body 31, and the grouting pipe 32 is selectively assembled in the model box 10. When the grouting pipe 32 is assembled in the model box 10, the slurry preparation body 31 is used to inject slurry into the model box 10 through the grouting pipe 32. The slurry can form a high-strength consolidated body, which is used to simulate the actual engineering environment of the post-grouting piles, so as to study the bearing properties, deformation characteristics and other bearing properties of the post-grouting piles under different conditions and the pile-soil interaction.

[0072] Furthermore, if Figure 5 and Figure 6 As shown, the multifunctional model testing device 100 may further include a moving device 317, on which the grouting mechanism 30 is mounted. The moving device 317 may be provided with a universal wheel 318, which can facilitate the grouting mechanism 30 to be moved to the vicinity of the model box 10 for grouting into the model box 10, thereby reducing the labor intensity of the test personnel, and a shock-absorbing spring may be installed in the universal wheel 318 for shock absorption of the universal wheel 318, and a brake pad may also be installed to stop the moving device 317.

[0073] The chassis of the mobile device 317 may be provided with a plurality of support plates 319, and the support plates 319 may be used to support the mobile device 317. The support plates 319 may be installed with a driving mechanism, such as a motor, a gear, or a rotating rod. The driving mechanism may be used to drive the support plates 319 to extend and retract. When the mobile device 317 needs to move, the support plates 319 are retracted by the driving mechanism to separate the support plates 319 from the ground, so as to facilitate the movement of the mobile device 317. When the mobile device 317 stops, the support plates 319 are extended and attached to the ground by the driving mechanism. , the support plate 319 can support the mobile device 317, further improving the stability of the mobile device 317. The driving mechanism can be equipped with devices such as slide grooves, support slide bars, and shock-absorbing springs. The designs of slide grooves, support slide bars, etc. can realize the telescopic function of the support plate 319. The shock-absorbing spring can reduce accidents caused by shaking or deviation. The support plate 319, support slide bars, etc. provide additional support for the grouting mechanism 30, thereby improving the stability of the grouting mechanism 30, making the grouting mechanism 30 more stable when facing complex terrain. The design of the support plate 319 can ensure the stability and reliability of the slurry preparation body 31 during the mixing and grouting process, and provide a stable working environment for the grouting mechanism 30. The shock-absorbing spring can absorb and disperse the vibration of the grouting mechanism 30 during operation, and the combined use of the support plate 319, support slide bars, shock-absorbing springs, etc. can share the load together, reduce the force and vibration of the components, and thus extend the working life of the grouting mechanism 30.

[0074] According to some embodiments of the present invention, Figure 5 and Figure 6As shown, the slurry preparation body 31 includes: a slurry storage tank 311, a first stirring structure 312, a second stirring structure 313 and a slurry transport structure 314. A slurry preparation chamber 315 and a slurry storage chamber 316 are formed in the slurry storage tank 311. The slurry preparation chamber 315 is located above the slurry storage chamber 316, and the slurry preparation chamber 315 and the slurry storage chamber 316 are selectively connected. The first stirring structure 312 is arranged in the slurry preparation chamber 315, and the second stirring structure 313 is arranged in the slurry storage chamber 316. The slurry transport structure 314 is connected between the slurry storage chamber 316 and the grouting pipe 32. The slurry transport structure 314 is used to transport the slurry in the slurry storage chamber 316 to the grouting pipe 32.

[0075] The slurry storage tank 311 is used to store slurry, the first stirring structure 312 and the second stirring structure 313 are used to stir the slurry, and the slurry transport structure 314 is used to transport the slurry. A slurry preparation chamber 315 and a slurry storage chamber 316 are formed in the slurry storage tank 311. The slurry preparation chamber 315 is located above the slurry storage chamber 316, and the slurry preparation chamber 315 and the slurry storage chamber 316 are selectively connected, so that the slurry is preliminarily mixed and stirred in the slurry preparation chamber 315. After the slurry reaches the consistency and uniformity required by the test, the slurry preparation chamber 315 and the slurry storage chamber 316 are connected, so that the slurry stirred in the slurry preparation chamber 315 flows into the slurry storage chamber 316 for storage. A filter can be provided between the slurry preparation chamber 315 and the slurry storage chamber 316 to filter impurities in the slurry, so as to avoid the slurry in the preparation process directly mixing into the slurry storage chamber 316, and ensure the injectability and stability of the slurry in the slurry storage chamber 316. It can be explained that a valve can be provided between the slurry preparation chamber 315 and the slurry storage chamber 316 to control whether the slurry preparation chamber 315 and the slurry storage chamber 316 are connected.

[0076] The first stirring structure 312 is arranged in the slurry preparation chamber 315, responsible for preliminary mixing of the raw materials to ensure the uniformity and stability of the slurry. The second stirring structure 313 is arranged in the slurry storage chamber 316 to further stir the slurry to prevent the slurry from stratification or precipitation during storage, and to maintain the fluidity and injectability of the slurry. The slurry transport structure 314 is connected between the slurry storage chamber 316 and the grouting pipe 32. The slurry transport structure 314 is used to transport the slurry in the slurry storage chamber 316 to the grouting pipe 32, so that the slurry can be injected from the slurry preparation body 31 into the model box 10. By controlling the start and stop of the slurry transport structure 314, the slurry injection amount and injection speed can be accurately controlled, which helps to ensure that the slurry supply during the grouting process is stable and continuous, and improve the grouting efficiency and quality.

[0077] Furthermore, the first stirring structure 312 may be connected to the first motor 1, the second stirring structure 313 may be connected to the second motor 2, the slurry transport structure 314 may include a third motor and a grouting pipe 32, the first motor 1, the second motor 2, and the third motor are all connected to the control device in communication, and the control device can control the operation of the first motor 1 and the second motor 2 in real time to change the stirring speed of the first stirring structure 312 and the second stirring structure 313, and the control device can also control the operation of the third motor in real time to adjust the grouting pressure and grouting flow of the slurry, so as to adapt to the grouting requirements of the test. The high degree of automation and mechanization of the slurry preparation, storage and transportation process allows the grouting work to be carried out more efficiently, helps to shorten the test time, and thus can improve the test efficiency.

[0078] According to some embodiments of the present invention, Figure 5 and Figure 7 As shown, when the grouting pipe 32 is assembled in the mold box 10 , the force applying device 50 is used to pull the grouting pipe 32 out of the mold box 10 .

[0079] When the model pile 11 is buried, the grouting pipe 32 can be wrapped around the model pile 11 through the raw material tape until the model pile 11 is buried, so as to facilitate the subsequent uniform grouting. There can be multiple grouting pipes 32, and multiple grouting pipes 32 can be evenly distributed around the model pile 11 to ensure that the grouting slurry can be evenly distributed. Figure 7 As shown, when grouting is completed, the grouting pipe 32 can be connected to the force device 50, and a plurality of pulleys can be connected to the mounting beam. The grouting pipe 32 is sequentially passed through the plurality of pulleys and connected to the force device 50. The grouting pipe 32 can be pulled out of the model box 10 through the force device 50. The friction force when the grouting pipe 32 is pulled out can be reduced, thereby reducing the degree of damage to the soil and the grouting body, helping to maintain the integrity of the grouting body and ensuring the grouting effect.

[0080] It can be explained that, in the process of pulling out the grouting tubes 32, in order to compensate for the disturbance caused by the grouting tubes 32 to the model piles 11 during the pulling out process, after pulling out one of the grouting tubes 32, the remaining grouting tubes 32 that have not been pulled out can be used for appropriate supplementary grouting operations. Taking eight grouting tubes 32 as an example, after pulling out two opposite grouting tubes 32 in turn, the remaining four grouting tubes 32 next to the two pulled out grouting tubes should be used for appropriate supplementary grouting, and so on, until all the grouting tubes 32 are completely pulled out, let it stand for a period of time, and the grouting work is completed.

[0081] After the grouting work is completed, the test can be started. The test may include a vertical load test, a vertical pull-out test, and a horizontal load test of the model pile 11. Figure 8-Figure 10 Experiments in three conditions.

[0082] Before performing the vertical downward pressure test on the model pile 11 in the first state, the support seat 20, the mounting beam 40, the model pile 11, and the force applying device 50 need to be adjusted to the following positions: Figure 8 The position shown is matched and assembled, and the force applying device 50 is controlled by the control device to gradually apply a vertical downward load to the mounting beam 40 to perform a vertical load test on the model pile 11. The detection mechanism on the model pile 11 can provide reliable data support for the test personnel to conduct research.

[0083] Before conducting the vertical pull-out test of the model pile 11 in the second state, the support base 20, the mounting beam 40, the model pile 11, and the force applying device 50 need to be adjusted to the following positions: Fig. 9 The position shown is matched and assembled, and the force applying device 50 is controlled by the control device to gradually apply a vertical downward load to the mounting beam 40 to perform a vertical pull-out test on the model pile 11. The detection mechanism on the model pile 11 can provide reliable data support for the test personnel to conduct research.

[0084] Before conducting the horizontal load test of the model pile 11 in the third state, the support base 20, the mounting beam 40, the model pile 11, and the force applying device 50 need to be adjusted to the following conditions: Fig.10 The position shown is matched and assembled, and the force-applying device 50 is controlled by the control device to apply different horizontal loads to the mounting beam 40 to perform a horizontal tensile test on the model pile 11. The detection mechanism on the model pile 11 can provide reliable data support for the test personnel to conduct research.

[0085] Therefore, different types of loads with accurate values ​​can be applied to the model pile 11 without frequent manual pressure replenishment or application of weights, which reduces interference and greatly improves the accuracy of the load applied to the model pile 11 and the test efficiency. In addition, the test device has a simple structure and low operation complexity, so a single person can perform the test operation.
