Description

Technical Field

[0001] The present disclosure relates to the technical field of test models, and in particular to a slope test device. Background Art

[0002] The slope model test chamber is constructed by building an external steel frame, then constructing a slider bed using a brick-concrete structure and filling the slope. Once completed, the mechanisms governing landslide development can be studied. In related art, the steel frame of the model test chamber is non-detachable, and the slider bed's slope is limited to a specific range, making it difficult to adjust the slope's gradient. To determine how different slopes affect landslide development using the slope model test chamber, only a rough range of slider bed slopes can be pre-fabricated, and then the slope is filled for model testing. This makes it difficult to accurately simulate the optimal slope range for landslides, which in turn affects the accuracy of the test results. Utility Model Content

[0033] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0034] In this disclosure, unless otherwise stated, directional words such as "upper, lower, high, low, top, bottom" generally refer to the orientation of the corresponding component or structure in the direction of gravity. Figure 1The directions of the drawings shown. "Inside" and "outside" refer to the inside and outside of the corresponding component outlines. In addition, it should be noted that the terms used, such as "first" and "second", are used to distinguish one element from another and do not have sequentiality or importance. In addition, in the description with reference to the drawings, the same symbols in different drawings represent the same elements. The above definitions are only used to explain and illustrate the present disclosure and should not be understood as limiting the present disclosure.

[0035] For ease of understanding, please refer to the attached Figures 1 to 5 , the specific structure and working principle of the present disclosure are explained in detail with reference to the embodiments.

[0036] The present disclosure relates to a slope test device that can flexibly adjust the slope of a slope model 2 to be tested, so as to obtain more accurate test data and better test results. Figure 1 and Figure 2 The slope test device disclosed herein includes a housing 1, a slope model 2, a precipitation component 3, and an adjustment component 4. The housing 1 may be rectangular and have a hollow inner cavity for accommodating other components of the test device. The slope model 2 and the adjustment component 4 are located in the inner cavity of the housing 1. The precipitation component 3 is located at the top of the housing 1. The precipitation component 3 can spray fluid into the housing 1 to simulate the effect of precipitation on the slope model 2. The slope model 2 includes a slope surface 21, which is rotatably connected to the adjustment component 4. The slope surface 21 can rotate relative to the adjustment component 4 through the action of the adjustment component 4 to change the slope of the slope surface 21 so that the slope of the slope surface 21 meets the appropriate test requirements.

[0037] Since the slope testing device disclosed herein can adjust the slope of the slope surface 21 in the slope model 2 through the adjustment component 4, the slope testing device disclosed herein can flexibly adjust the slope of the slope surface 21 according to different test requirements when conducting tests, so as to meet the test requirements and obtain more accurate test data. There is no need to frequently replace the slope models 2 with different slopes to complete different tests, thereby reducing the test time and the number of slope models 2 with different slopes to be manufactured, saving manpower and material resources.

[0038] In one embodiment of the present disclosure, see Figure 1 and Figure 4The adjustment component 4 includes a telescopic rod 41. The telescopic rod 41 can be a component that can be telescoped, such as a cylinder or an oil cylinder, or can be telescopically extended by a mechanical structure through sockets, bolts, etc., or other telescopic structures known to those skilled in the art, which will not be described in detail here. The telescopic end of the telescopic rod 41 is rotatably connected to the end of the slope 21. The end of the slope 21 can be any point on one side of the slope 21, as long as it can be rotatably connected to the telescopic rod 41. When the end of the telescopic rod 41 is extended or retracted, it can drive the slope 21 to rotate relative to the telescopic rod 41 to change the slope of the slope 21 and meet the requirements of different tests. The telescopic rod 41 can be rotatably connected to the slope 21 by directly connecting with a rotating shaft or by connecting with components such as bearings. This disclosure does not limit this.

[0039] In one embodiment of the present disclosure, see Figure 1 and Figure 4 The slope 21 is rectangular, and four telescopic rods 41 are provided, each located at the four corners of the slope 21 and rotatably connected to drive the slope 21 to rotate. Setting the slope 21 to a rectangle facilitates test measurements. Of course, in other embodiments, the slope 21 can also have other shapes, depending on actual conditions, and this disclosure does not limit this. Since the telescopic rods 41 are connected to the four corners of the slope 21, in order to prevent the telescopic rods 41 from interfering with the slope 21 during its rotation, the connection between the end of the telescopic rod 41 and the slope 21 can be configured to slide along the extension direction of the slope 21. When the slope 21 rotates, it slides a certain distance relative to the slope 21 according to the rotation angle to avoid interference. Of course, in other embodiments, the end of the telescopic rod 41 not connected to the slope 21 can also be configured to be rotatable, so that the other end of the telescopic rod 41 also rotates when the slope 21 rotates to avoid interference.

[0040] In one embodiment of the present disclosure, see Figure 1 and Figure 3 Slope 21 is provided with seepage holes 211, and a water storage tank 212 is located at the bottom of slope 21. The provision of seepage holes 211 and water storage tank 212 on slope 21 allows for testing the water retention capacity of slope 21 when placed on different soils. During the test, the slope 21 is first adjusted to an appropriate angle, the soil to be tested is then laid on the slope 21, and finally, the precipitation assembly 3 sprays fluid to simulate rainfall. After the rainfall simulation is complete, personnel can calculate the water retention capacity of slope 21 when covered with the soil to be tested based on the mass of fluid in water storage tank 212.

[0041] In one embodiment of the present disclosure, see Figure 1 and Figure 4The slope model 2 includes multiple slope surfaces 21, and the adjustment component 4 includes multiple telescopic rods 41. Each slope surface 21 is connected to a different telescopic rod 41, and the slope can be adjusted independently. Figure 4 The slope model 2 includes two slope surfaces 21, each of which is rectangular and rotatably connected to four telescopic rods 41 at its four corners. When it is necessary to test the water retention capacity of the slope surfaces 21 at different slopes, the two slope surfaces 21 can be set to different angles and then tested simultaneously, thereby reducing test time and improving test efficiency. Of course, multiple slope surfaces 21 can also be used to test different soils at the same slope, or the two slope surfaces 21 can be adjusted to abutting slopes to increase the length of the test slope 21. Of course, in other embodiments, the slope surfaces 21 can also have other shapes and numbers, which can be determined according to actual conditions and are not limited by this disclosure.

[0042] In one embodiment of the present disclosure, see Figure 1 and Figure 4 The slope model 2 includes multiple slopes 21. A receiving plate is provided on the slope 21 at the end. The receiving plate can be a horizontal straight plate and is located at the end of the slope 21. The receiving plate can receive the soil on the slope 21 when it slides down from the slope 21 under the action of the precipitation assembly 3, making it easier for workers to recover the soil after the test is completed. It can also prevent the soil from falling into the box 1, reducing the difficulty of cleaning the box 1 for workers.

[0043] In one embodiment of the present disclosure, see Figure 2 and Figure 5 The box 1 includes a bottom plate 11, columns 12, side plates 13, and a top plate 14. These four panels constitute the entire box 1 and enclose an inner cavity. The columns 12 are located on the bottom plate 11, on which the slope model 2 and the adjustment component 4 are also located. The top plate 14 is located on top of the columns 12, and the precipitation component 3 is located on the top plate 14, so that the fluid can be sprayed on the slope model 2 in the box 1.

[0044] In this embodiment, the box body 1 is rectangular, which is easy to manufacture and has good stability. Figure 2 The side panels 13 may include a first side panel of greater height and a second vertical panel of less height. One end of the first vertical panel abuts the bottom panel 11, and the other end abuts the top panel 14, thereby closing the box body 1. One end of the second vertical panel abuts the bottom panel 11, and the other end is spaced a certain distance from the top panel 14 to form a gap for observing the interior of the box body 1. A wire hole may also be provided on the second vertical panel to facilitate the passage of wires in the adjustment assembly 4. Of course, in other embodiments, the box body 1 may also have other structures, which may be determined based on actual conditions and are not limited in this disclosure.

[0045] In one embodiment of the present disclosure, see Figure 2 and Figure 5 The column 12 includes a first column 121, a second column 122 and a limiter 123. The first column 121 is fixedly connected to the bottom plate 11, and the second column 122 can slide on the first column 121 along the extension direction of the first column 121. The top plate 14 is fixedly connected to the top of the second column 122, and the limiter 123 can limit the position of the second column 122 on the first column 121, so that the first column 121 and the second column 122 remain relatively stable. By sliding the second column 122 on the first column 121, the height of the top plate 14 relative to the bottom plate 11 can be flexibly adjusted, thereby changing the height of the precipitation component 3 located on the top plate 14 from the slope model 2, and adjusting the height of the sprayed fluid to simulate different precipitation conditions.

[0046] In one embodiment of the present disclosure, see Figure 3 and Figure 4 The slope testing device also includes a vibration assembly 5. The slope model 2 and the adjustment assembly 4 are both located on the vibration assembly 5. The vibration assembly 5 can cause the slope model 2 to vibrate, thereby simulating the conditions of the slope model 2 during an earthquake. The provision of the vibration assembly 5 increases the variety of tests that the slope testing device can perform on the slope model 2. It can not only perform tests related to precipitation conditions on the slope model 2, but also tests related to earthquake conditions on the slope model 2.

[0047] In one embodiment of the present disclosure, see Figure 3 and Figure 4 , the vibration component 5 includes a connecting plate 51, a spring 52 and a vibration shaft 53. The slope model 2 and the adjustment component 4 are located on the top surface of the connecting plate 51, one end of the vibration shaft 53 is fixedly connected to the bottom surface of the connecting plate 51, and the other end is fixedly connected to the bottom plate 11 of the box body 1. The spring 52 is sleeved on the vibration shaft 53, which plays a role in increasing the elastic force. When it is necessary to simulate an earthquake, the vibration shaft 53 can be started to drive the connecting plate 51 to vibrate, and then the slope model 2 on the connecting plate 51 can also vibrate synchronously, which plays a role in simulating an earthquake. Of course, in other embodiments, the vibration component 5 can also have other structures, as long as it can drive the slope model 2 to vibrate to simulate an earthquake. The specific structure can be determined according to actual conditions, and the present disclosure does not limit this.

[0048] In one embodiment of the present disclosure, see Figure 1 and Figure 6The precipitation assembly 3 includes a water tank 31, which is fixedly connected to the top surface of the box body 1. A water inlet 311 and a spray hole 312 are also provided on the water tank 31. Fluid can be added to the water tank 31 through the water inlet 311, and the spray hole 312 can pass through the top plate 14 of the box body 1, so that the fluid sprayed from the spray hole 312 can enter the box body 1. Of course, in other embodiments, a control component can also be provided in the precipitation assembly 3, and the control component can be used to control parameters such as the speed and flow rate of the fluid sprayed in the water tank 31, so that the slope test device of the present disclosure can simulate more precipitation effects. The present disclosure does not limit this.

[0049] When using the slope testing device disclosed herein, it is first necessary to adjust the slope of the slope surface 21 on the slope model 2. The adjustment process involves using the telescopic rod 41 to drive the slope surface 21 to rotate a certain angle, so that the slope surface 21 is at a suitable slope for testing. After the slope of the slope surface 21 is adjusted, the soil to be tested is laid on the slope surface 21. Finally, fluid is added to the water tank 31 so that the fluid can be sprayed out through the spray holes 312 on the water tank 31 to simulate precipitation. Of course, in other tests, the vibration shaft 53 can also be activated to drive the connecting plate 51 to vibrate to simulate earthquake conditions and perform seismic tests on the slope model 2.

[0050] The slope testing device disclosed herein is provided with an adjustment component 4, which can drive the slope surface 21 in the slope model 2 to rotate through the adjustment component 4, thereby changing the slope of the slope surface 21. The slope can be flexibly adjusted, avoiding the need for workers to frequently replace the slope model 2 when testing the slope model 2, and avoiding the need to manufacture multiple sets of slope models 2 for testing, thereby improving the efficiency of the test and saving manpower and material resources.
