Description

[0002] The highway slope disaster detection simulation experiment equipment in cold region usually refers to a forward and reverse inclined rock indoor vibration table (1), mainly composed of a vibration seat and a model box, the model box is internally provided with forward and reverse inclined rock, the influence of earthquake on the forward and reverse inclined rock is simulated through the vibration of the vibration seat, and a high-speed camera is usually used for shooting during the experiment to perform subsequent analysis and comparison.

The experimental process and results of simulating the disaster caused by earthquake by using the vibration table are introduced in detail. However, the design of the vibration table is based on non-frozen soil, and there is no rainwater simulation system. It can relatively stably provide the disaster caused by earthquake, but the simulation effect is poor in combination with the high situation of frozen soil and the change of frozen soil cold and hot, and the influence of rainwater scouring on the stability of the surface soil loss.

[0024] Shower nozzle 31 is provided with a plurality of through holes 311, and the aperture of the through hole 311 of the shower nozzle 31 closer to the middle of the simulation box 2 is larger. Since the order reverse rock bed 21 is arranged at both ends of the simulation box 2, and the height closer to the middle of the simulation box 2 is lower, combined with the characteristics that the precipitation in the cold mountainous area is more as the altitude is lower, the water spray amount needs to be changed along the height of the order reverse rock bed 21.

[0025] The support 22 is provided with a plurality of roots, and each support 22 is fixedly connected with a sleeve ring 32, the sleeve ring 32 is fixedly connected with a sleeve rod 33, and the end of the sleeve rod 33 away from the sleeve ring 32 is fixedly connected with the shower nozzle 31. The support 22 and the sleeve rod 33 are provided with a communication pipe 34. The present scheme is provided with three roots, which can be appropriately increased or reduced according to the width of the order reverse rock bed 21. The communication pipe 34 is erected on the support 22 or directly placed in the simulation box 2, and the side of the communication pipe 34 away from the shower nozzle 31 is connected with a water pump. The water pump is installed at the water storage place outside the simulation box 2.

[0026] The center of the shower nozzle 31 is fixedly connected with a tapered block 312, and the tip of the tapered block 312 points to the communication pipe 34. By arranging the support 22, the shower nozzle 31 can slide on the support 22, and different areas can be sprayed. Different areas can be compared by different water spray amounts.

[0027] As another embodiment, as Figure 4 and Figure 5As shown, the push assembly 4 of this application includes a fixed frame 41, a reversible motor 42, a threaded rod 43, a slider 44, a connecting rod 45, and a limiting ring 46. The fixed frame 41 is fixedly connected to the outer wall of the simulation box 2. The reversible motor 42 is fixedly connected inside the fixed frame 41. One end of the threaded rod 43 is fixedly connected to the output end of the reversible motor 42, and the other end of the threaded rod 43 is fixedly connected to the limiting ring 46. The limiting ring 46 is fixedly connected to the outer wall of the simulation box 2. The slider 44 is sleeved on the threaded rod 43 and slides on the threaded rod 43. One end of the connecting rod 45 is fixedly connected to the slider 44, and the other end of the connecting rod 45 is fixedly connected to the collar 32. The threaded rod 43 is parallel to the bracket 22.

[0028] The slider 44 has an internal thread and engages with the threaded rod 43. A collision sensor can be installed at the limiting ring 46. When the slider 44 slides to the limiting ring 46 and collides with the sensor, the reversible motor 42 reverses. In use, the reversible motor 42 is turned on, driving the threaded rod 43 to rotate. The slider 44 moves along the threaded rod 43 towards the limiting ring 46 as the threaded rod 43 rotates, and the connecting rod 45 and spray head 31 connected to the slider 44 move synchronously. When it reaches the appropriate position, the reversible motor 42 is turned off. When the slider 44 collides with the sensor, it means that the slider 44 has slid to the end of the threaded rod 43, and the reversible motor 42 reverses. The reversible motor 42 is turned off when the slider 44 slides to the appropriate position.

[0029] As another embodiment, such as Figure 1 As shown, the drainage component 5 of this application includes a drainage pipe 51 and a drainage outlet 52. The drainage outlet 52 is located at the bottom of the simulation box 2 and in the middle of the simulation box 2. The drainage pipe 51 passes through the drainage outlet 52 and is fixedly connected to the drainage outlet 52. A water guide channel 53 is fixedly connected to the bottom of the simulation box 2. The water guide channel 53 is inclined, and the lower end of the water guide channel 53 is higher than the opening of the drainage pipe 51. After the spraying is completed, some water will be absorbed by the syn- and syn-rock strata 21 or by its surface soil. The remaining water flows to the water guide channel 53 and is discharged from the drainage outlet 52.

[0030] As another embodiment, such as Figure 4 and Figure 5 As shown, the temperature control component 6 of this application includes a refrigerator 61 and a refrigeration pipe 62. The refrigerator 61 is fixedly connected to the top of the simulation chamber 2, and the refrigeration pipe 62 is fixedly connected to one side of the refrigerator 61, extending into the simulation chamber 2. The refrigerator 61 is used to cool the interior of the simulation chamber 2. The refrigerator 61 can be electrically connected to a controller, which controls the start-up time and temperature setting of the refrigerator 61, simulating the scenario of large temperature differences in spring and autumn by controlling temperature changes.

[0031] The working principle of the simulation experiment equipment for intelligent monitoring of disasters of a highway slope in a cold region is as follows: in use, the switch of the reversible motor 42 is turned on, the threaded rod 43 is driven to rotate, the sliding block 44 moves along the threaded rod 43 to the side of the limiting ring 46, and the connecting rod 45, the spray head 31 and the like connected with the sliding block 44 move synchronously. When the sliding block 44 collides with the sensor, it means that the sliding block 44 has been slid to the end of the threaded rod 43, the reversible motor 42 is reversed, and the reversible motor 42 is turned off when the sliding block 44 slides to the appropriate position. After adjusting the positions of the sleeve ring 32 and the spray head 31 according to the experimental setting, the water pump is turned on to spray in the simulation box 2. Since the through hole 311 of the spray head 31 closer to the middle of the simulation box 2 is smaller, the uneven characteristics of mountain precipitation can be simulated. After spraying, part of the water is absorbed by the reverse rock layer 21 or the surface soil, the remaining water flows to the water guide groove 53, and the water is discharged from the water outlet 52. The refrigeration time and temperature of the refrigerator 61 are input into the controller according to the experimental setting, so as to simulate the influence of temperature difference change on the reverse rock layer 21. The vibration table 1 is used to simulate the deformation and the like of the reverse rock layer 21 under the condition of earthquake.

[0032] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Any person skilled in the art can make many possible changes and modifications to the technical solution of the present application without departing from the scope of the technical solution of the present application, or modify it into equivalent embodiments with equivalent changes. Therefore, any modification, equivalent change and modification made to the above embodiments according to the technical solution of the present application, which does not depart from the content of the technical solution of the present application, belongs to the protection scope of the technical solution.
