Description

Technical Field

[0001] The invention relates to the field of environmental rock and soil technology, and in particular to a vegetation growth simulation and rooted soil shearing system for slopes in high-cold areas. Background Art

[0002] As an effective means to improve slope stability, the influence of vegetation roots on soil mechanical properties has gradually attracted attention. In the article "Study on the influence of root morphology and hierarchical structure on the mechanical properties of root-soil complex" (Soil and Water Conservation Bulletin, Vol. 44, No. 2, 2024.03), Xu Hua et al. conducted ryegrass growth parameter tests and direct shear tests to illustrate the influence of root morphology and hierarchical structure on the mechanical properties of root-soil complex and the soil consolidation mechanism. In the article "Analysis of the soil consolidation and slope protection effect of two herbaceous plants on red clay slopes" (Chinese Journal of Geotechnical Engineering, Vol. 37, No. 6, 2022.05), Wang Lianrui et al. took red clay slopes as an example, selected dogtooth grass and vetiver as slope protection plants, and through planting tests and direct shear tests, they found that both herbaceous plants have good slope protection effects. At present, certain results have been achieved in the research on the root-fixing mechanism, but the relevant research on the mechanical properties of rooted soil is still lacking. In addition, the existing research on the mechanical properties of rooted soil only focuses on common environmental conditions, and there is little research on the mechanical properties of rooted soil on slopes in high-altitude cold regions.

[0003] In terms of test equipment, the Chinese patent with the authorization announcement number CN219961492U discloses an indoor simulation system for plant growth on railway rock slopes in high-cold areas, including a rainfall simulation system, a simulation room, a sunshine simulation system and a temperature control simulation system. When working, it can simulate plant growth environments of different slopes and different environmental characteristics (sunshine, temperature, rainfall conditions, etc.), but the system cannot simulate the light changes in high-cold areas in real time when performing sunshine simulation, and cannot simulate plant growth environments of different slopes at the same time during cultivation, and cannot perform soil direct shear tests on samples on the original cultivation slope.

[0004] The Chinese patent with the authorization announcement number CN107782635B discloses an in-situ shear test system for soil, which solves the problem that it is difficult to provide accurate and constant vertical pressure and poor stability during the shearing process in the on-site in-situ shear test. However, the system has a low degree of automation and requires multiple manual debugging and sampling during the experiment, which still causes soil disturbance. When shearing tests are conducted on root-soil complexes on slopes at different angles, the growth angle of plant roots cannot be simulated, and the mechanical properties of the resulting root-soil complexes are biased.

[0005] In the experimental research related to the ecological restoration of rock slopes in alpine areas, it is an important condition for the success of the experiment to achieve a relatively realistic simulation of the plant growth environment in alpine areas and to be able to directly test the relevant mechanical properties. The experiments related to the ecological restoration of rock slopes in alpine areas have low operability, great difficulty in restoration, long time consumption, and low degree of automation. In the laboratory, cultivation cannot accurately simulate the plant growth environment, especially the simulation of actual plant root growth in slopes of different orientations (different strikes, inclinations, and inclinations); at the same time, the current direct shear test cannot be conducted in the in-situ environment of plant growth, that is, on the one hand, it is impossible to avoid the disturbance caused by sampling during the test process, and on the other hand, it is impossible to reflect the intertwined relationship between the root system and the soil in the direct shear test specimen. Therefore, the present invention proposes a vegetation growth simulation and rooted soil shear system for slopes in alpine areas to solve the problems existing in the prior art.

[0036] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with examples. The examples are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0037] The total area of ​​my country's alpine regions is about 2.9 million square kilometers, accounting for 43.5% of my country's land area. With global climate change and the increase of human engineering activities, more and more roads and railways will pass through these areas. Take the Sichuan-Tibet Railway as an example. The Sichuan-Tibet Railway is a top priority in the national major construction project plan and an important part of the Tibet Autonomous Region's external transportation channel. The Sichuan-Tibet region is located in a high-altitude cold area, the ecosystem is relatively poor and fragile, and ecological restoration is extremely difficult. Therefore, the ecological environment in the alpine regions faces severe challenges. As an important part of my country's regional landforms, the alpine regions have unique geographical and climatic conditions that make the ecological restoration and slope stability in the region face huge challenges.

[0038] Therefore, in the relevant research on ecological restoration technology of rock slopes in alpine areas, an integrated system is needed that can provide indoor growth simulation function and conduct shear tests on rooted soils suitable for slopes of different occurrences.

[0039] Therefore, according to Figure 1-Figure 17 As shown, this embodiment proposes a system for simulating the growth of vegetation on slopes in alpine areas and shearing rooted soil, including a machine base, on which a maintenance system 1, a layout platform 2 and a direct shear system 3 are arranged.

[0040] The maintenance system 1 includes a maintenance shell, which includes a maintenance top 31, a front door 32 and a side door 33. The maintenance top 31 is located at the top of the system, and an adjustable precipitation unit 8 and a lighting unit 9 are installed inside it. The precipitation unit 8 is characterized by being able to control the density and flow of water droplets to simulate the precipitation amount and precipitation uniformity during actual precipitation. The lighting unit 9 is characterized by being able to simulate the changes of the sun's rays rising in the east and setting in the west during the day. Correspondingly, the side door 33 is characterized by having an atmosphere unit 10 integrated inside, which is characterized by controlling the temperature, air pressure, humidity, wind force and other environmental conditions inside the maintenance system 1 by exhaust. At the same time, the side door 33 and the front door 32 are both provided with thermal insulation sealing strips 34 inside, and a handle 35 is installed on the outside of the side door 33. When the layout platform 2 completely enters the maintenance system 1, the side door 33 and the front door 32 are closed, and the system is started through the main control panel 30, and the effect of in-situ cultivation of slope protection plants in the real high-cold climate environment is achieved through the combined action of the precipitation unit 8, the illumination unit 9, and the atmosphere unit 10. After maintenance, the layout platform 2 enters the direct shear system 3 again to conduct mechanical property research.

[0041] The layout platform 2 includes a slide rail 4, which is driven by a transverse motor 5. Specifically, the transverse motor 5 is fixed in the machine base, and a motor shaft 38 is installed at its output end. The motor shaft 38 is connected to the slide rail 4. When the transverse motor 5 is working, it can drive the slide rail 4 to move in the horizontal direction, and then the layout platform 2 can move horizontally in the machine base to enter the corresponding position.

[0042] A culture rack 6 is installed on the slide rail 4 through a rotating component, and the rotating component includes a lower plate 11, which is fixedly connected to the slide rail 4, a sleeve slide 12 is installed on the lower plate 11, and the upper end of the sleeve slide 12 is connected to the upper plate 13 through a bearing, and a rotating motor 14 is installed on the inner side of the sleeve slide 12, the rotating motor 14 is located in the upper sleeve of the sleeve slide 12, and the output end of the rotating motor 14 is connected to the upper plate 13, when working, the rotating motor 14 drives the upper plate 13 to rotate, further, in this embodiment, the sleeve slide 12 is composed of an upper sleeve and a lower sleeve, the upper sleeve can move up and down in the lower sleeve, and its driving method is driven by an electric hydraulic cylinder, the electric hydraulic cylinder is arranged on the outer side of the lower sleeve, and its output end is fixedly connected to the upper sleeve.

[0043] An experimental box 7 is installed on the culture rack 6 through a slope control component, and the experimental box 7 is provided with several groups. In this embodiment, the experimental box 7 is evenly provided with six groups. The slope control component includes a contact 15, a double connecting rod 16 and a regulating motor 17. A rack plate is installed (welded) at the front end of the regulating motor 17 to drive it to move forward and backward. A gear is installed at the end of the double connecting rod 16, and the gear is meshed with the rack plate. The other end of the double connecting rod 16 is connected to the contact 15. A loose-leaf 18 is provided at the bottom of the experimental box 7, and the upper end of the contact 15 contacts the loose-leaf 18. The culture rack 6 itself is provided with two groups of symmetrically arranged baffles, and the fixed end of the loose-leaf 18 is fixed between the two groups of baffles, and the movable end is used to install the experimental box 7. Therefore, when the regulating motor 17 controls its forward and backward movement, it drives the double connecting rod 16 to flex and extend, thereby adjusting the height of the contact 15 and the loose-leaf 18 it touches to simulate different slopes in high-cold areas.

[0044] There are circular holes at the four corners of the experimental box 7 for inserting pins to fix the upper and lower halves of the box. The side of the experimental box 7 is installed with a shear end 19, a distance meter 20 and a locking piece 21 by bolts, wherein the locking piece 21 includes a right-angle plate 22, the upper end of the right-angle plate 22 is in contact with the distance meter 20, and a fixed motor 23 is installed on the inner side of the right-angle plate 22. The output end of the fixed motor 23 is in contact with the experimental box 7 through an eccentric wheel 24. The fixed motor 23 drives the eccentric wheel 24 to rotate so that the experimental box 7 can be fixed in the same position of its loose-leaf 18 during the direct shear test.

[0045] The direct shear system 3 is installed with a direct shear component and an electronic control component. The direct shear component includes a slider 25. The slider 25 is located at the top of the machine base. An axial press 26 and a shear motor 27 are installed below the slider 25. The axial press 26 and the shear motor 27 are fixed to the slider 25 in pairs. A pressure plate 37 is installed at the output end of the axial press 26. Specifically, the axial press 26 moves downward through the internal motor and the sleeve to allow the pressure plate 37 to provide longitudinal positive stress to the soil in the experimental box 7. The output end of the shear motor 27 is installed with a front end groove interface 28. The front end groove interface 28 is adapted to the shear end 19. The shear motor 27 can adjust the angle longitudinally around the axis and connect to the shear end 19 through the front end groove interface 28 for shearing. Correspondingly, a drive rail 39 is also provided in the direct shear system 3. The drive rail 39 connects the maintenance system 1, the layout platform 2, and the direct shear system 3, so that the layout platform can move between the maintenance system 1 and the direct shear system 3. A pipeline area 36 is provided at the lower part of the direct shear system 3 for integrating water pipes, circuits, etc.

[0046] Correspondingly, the electronic control component includes a camera 29 and a master control screen 30 . The camera 29 and the master control screen 30 are electrically connected. The master control screen 30 is the master control end of the system. All electronic components in the system are controlled by the master control screen 30 .

[0047] The present invention is composed of a layout platform, a maintenance system, and a direct shear system. Six groups of experimental boxes in the layout area of ​​the layout platform are filled with soil designed for the experiment and planted. The upper and lower boxes are fixed with latches. The inclination angle of the loose leaf is adjusted to multiple slopes required by the experiment through a motor. The experimental box is placed on the loose leaf and locked through a locking piece to ensure the relative fixation of the experimental box and the loose leaf. The horizontal motor is controlled to start on the master control screen, and the layout platform is pushed into the maintenance system through the motor shaft and the slide rail for maintenance and cultivation.

[0048] The maintenance system is characterized by adjustable precipitation units and illumination units installed on the inner side of the top of the inner wall of the box. The precipitation unit is characterized by being able to control the density of water droplets and the flow of water to simulate the precipitation amount and uniformity of precipitation during real precipitation; the illumination unit is characterized by being able to simulate the changes of the sun's rays rising from the east and setting from the west during the day. The side door is characterized by an integrated atmosphere unit, which is characterized by controlling the temperature, air pressure, humidity, wind force and other environmental conditions inside the maintenance system by exhaust. At the same time, the side door and the front door are both equipped with thermal insulation sealing strips. When the lofting platform completely enters the maintenance system, the side door and the front door are closed and the climate environment data preset in the master control screen are started. The precipitation unit, the illumination unit and the atmosphere unit work together to achieve the effect of in-situ cultivation of slope protection plants in the real high-cold climate environment. When the maintenance cycle required for the experiment is over, the lofting platform is pushed into the direct shear system through the motor shaft and the slide rail for mechanical property testing.

[0049] The experimental box is fixed with a shear end and a distance meter on the side by bolts. After the layout platform is completely put into the direct shear system, first take out the pins that fix the upper and lower boxes and process the samples. The slide rail controls the total height of the culture rack through the internal sleeve slide, the shear motor adjusts the angle, the front end of the groove interface is fixed to the shear end through the pin shaft, and the shaft press covers the pressure plate on the surface of the soil in the experimental box and applies positive stress, and starts the direct shear test on the three groups of samples. After the test, the main console records the data through the distance meter and the shear motor to analyze and obtain the mechanical properties of the rooted soil. The rotating motor and bearing allow the culture rack to rotate on the console. After rotation, repeat the above steps to obtain the shear strength data of the six groups of samples relative to them.

[0050] Experimental verification:

[0051] Taking the optimal ratio exploration experiment of three plants, white clover, bermudagrass and alfalfa, as an example, six experimental boxes were filled with planting soil to a height of 10 cm, and the seeds of three plants, white clover, bermudagrass and alfalfa, were planted on the surface of the soil layer in three ratios of 2:2:3, 3:3:8 and 1:1:5, respectively. Two boxes were planted for each ratio, covered with 1 cm thick soil, fixed on the lofting platform, and then the lofting platform was adjusted to the expected simulated slope by adjusting the loose-leaf. And refer to the environmental data of the alpine region: annual rainfall of 500 mm, average temperature of 1.2-11 degrees Celsius, air pressure of 660 hPa, and average daily light of 8.2 hours. This environmental data was input into the main control console, and the environment in the maintenance system was adjusted. Then the plants were cultivated in the maintenance system for a period of 30 days. The bud rate of plants with different ratios was observed every 5 days. During the maintenance period, the main door and side door of the maintenance system were closed. The maintenance situation can be observed through the main control console and the system environmental data can be adjusted in real time to simulate the reference alpine region environment.

[0052] On the 30th day, maintenance was stopped, the side door of the maintenance system was opened, and the layout platform was pushed out of the maintenance system through the main control console. The plant stems and leaves above the soil in the experimental box were manually cut off, leaving only the vegetation root system and the soil complex, and then pushed into the direct shear system for direct shear test.

[0053] After the layout platform is pushed in, the expected simulated slope is readjusted through the main control console, the locking parts are controlled to release the connection of the test box, the pressure plate height is adjusted through the axial press, and the pressure plate is aligned with the test box. The expected transverse shear angle, shear rate and vertical load size are set on the main control console, and the direct shear test is carried out on the test box. The main control console obtains the mechanical properties of rooted soils with three ratios after 30 days of cultivation in the high-cold area slope environment by analyzing the displacement meter deformation and the shear strength of the sample during the shear process.

[0054] Finally, through the centralized analysis of the germination rates of different ratios recorded in the maintenance system and the mechanical properties of different ratios recorded in the direct shear system, it was concluded that 3:3:8 is the best ratio, 1:1:5 is the second, and 2:2:3 is the worst. That is, when the ratio of white clover, bermudagrass, and alfalfa is 3:3:8, it can not only ensure the greening effect of the slopes in the high-cold area, but also improve the stability of the slopes.
