They are mostly caused by short-term heavy rainfall or long-term low-to-medium-intensity rainfall. They often occur in groups in areas with similar geological and topographical conditions, causing serious damage to residents' lives, property and infrastructure. Due to the wide distribution of mountain disasters such as landslides and debris flows, detailed monitoring is relatively difficult, which makes most researchers use physical model experiments. However, the current physical model experimental devices are usually small in scale and the model structure is single in function, which makes it difficult to reflect the real mountain disaster situation, and cannot meet the simulation and prevention and control measures of large-scale and multi-scale mountain disasters under the joint action of multiple factors, which hinders the development of research and prevention of mountain disasters such as landslides and debris flows.

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. In the present invention, unless otherwise specified, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the drawings; while "inside" and "outside" refer to the outline of the device.

[0030] See also Figure 1 , Figure 3 and Figure 4 In a first aspect, an embodiment of the present application provides an artificial rainfall and seepage device for simulating large-scale mountain disaster dynamics, comprising a material box, the bottom of which is inclined, and an openable gate is provided on one side of the material box;

[0031] A water pool is located on a side of the material box away from the gate, and a portion of the water pool adjacent to the material box is provided with multiple rows of through holes;

[0032] The artificial rainfall mechanism is located above the material box.

[0033] It can be understood that the material box is used to load materials and water. The maximum amount of materials used at one time for simulating large-scale mountain disaster dynamics experiments can be up to 500 cubic meters. Large material trucks transport the materials along the winding mountain access road to the top platform and pile them in the material box on the top platform. In addition, the effects of slope plants, retaining measures, slope reinforcement, etc. on soil stability can be evaluated in the material box. Soil is piled up in the internal environment of the material box, and different methods are used to reinforce and protect the slope, so as to deeply understand and analyze the impact of different methods on slope stability; the role of slope plants: evaluate how plants growing on the slope affect the stability of the soil. Plants play a positive role in the stability of the slope by fixing the soil through their roots, reducing soil erosion, and regulating surface water runoff; the effect of retaining measures: examine and analyze the actual effects of various retaining structures in preventing soil sliding and maintaining slope stability. These structures enhance the overall stability of the soil by providing additional support or resistance; slope reinforcement methods: evaluate the degree of improvement of soil stability by different slope reinforcement technologies. These technologies achieve the purpose of slope reinforcement by improving the mechanical properties of the soil, increasing the shear strength and overall stability of the soil; in short, through simulation experiments in the material box, we can more accurately understand the role of these methods and their specific impact on soil stability, which is of great significance to the design, construction and maintenance of slope projects, and helps to ensure the safety and stability of slope projects.

[0034] It can be understood that the water pool is a seepage device used to simulate large-scale mountain disaster dynamics experiments. The seepage volume and the seepage water level are controlled by controlling the water level in the water pool. The water in the water pool continuously seeps into the soil in the material box through multiple rows of holes, which is used to simulate the seepage situation under natural conditions.

[0035] It can be understood that the artificial rainfall mechanism is used to simulate natural rainfall with different rainfall intensities, different rainfall amounts, and different rainfall durations.

[0036] In some embodiments, guardrails are provided on both sides of the upper portion of the material box.

[0037] It is understandable that guardrails can form a physical barrier to prevent people from accidentally falling when approaching the edge.

[0038] The present application uses multiple rows of through holes to fully mix water flow and materials layer by layer to form a debris flow in the material box, which can effectively reduce the workload of manual or mechanical mixing and improve work efficiency; the setting of multiple rows of through holes on the water pool connected to the material box realizes the seepage of the large-scale mountain disaster dynamics experiment, and the rainfall is realized by the artificial rainfall mechanism set above the material box. Under the conditions of rainfall, seepage, rainfall and seepage coupling, the whole process of converting the large-scale landslide into debris flow in the large-scale mountain disaster dynamics experiment is realized, that is, the simulation and prevention and control measures of multiple factors (rainfall, seepage, rainfall and seepage coupling) can be realized. In addition, the present device provides important guidance for analyzing the starting mechanism of large-scale landslides and determining the critical conditions for the start of debris flows, and for disaster forecasting and early warning; the present application can simulate the rainfall process and seepage process in the natural environment, including rainfall intensity, rainfall amount, seepage amount, etc., and provides experimental conditions for the study of the disaster mechanism and prevention and control measures of landslides and debris flows.

[0039] This application can record the change process of the slope under different rainfall conditions (light rain (10mm / 24h), moderate rain (25mm / 24h), heavy rain (50mm / 24h), rainstorm (70mm / 24h), heavy rainstorm (150mm / 24h), and extremely heavy rainstorm (300mm / 24h)) and different seepage rates (the water level in the pool reaches the first row of through holes, the second row of through holes, the third row of through holes, and the fourth row of through holes in multiple rows of through holes). Until obvious slope displacement occurs, the occurrence of landslide is determined through the detection system.

[0040] The present application uses an artificial rainfall control system to adjust the rainfall amount of water flowing through rainfall nozzles and the seepage amount of multiple rows of holes to change the rainfall and seepage conditions. The rainfall seepage is then continued until the slope is fully saturated and a debris flow is formed after the gate is opened. The landslide is then transformed into a debris flow, and the artificial rainfall mechanism is used to record the time point of the transformation, rainfall amount, rainfall intensity, rainfall duration, etc.

[0041] See also Figure 1 and Figure 3 In some embodiments, the artificial rainfall mechanism includes a water supply tank located on one side of the water pool, a plurality of rainfall brackets located above the tank, each of the rainfall brackets is provided with a plurality of rainfall nozzles, the water supply tank is connected to the nozzles through a first water supply pipe, a first pressure pump is provided between the water supply tank and the first water supply pipe, and a first valve is provided on the first water supply pipe.

[0042] It can be understood that the water supply tank is connected to the sprinkler head via the first pressure pump, the first valve, and the first water supply pipeline, and is used to simulate natural rainfall under different rainfall intensities, different rainfall amounts, and different rainfall durations.

[0043] See also Figure 2For example, there are 7 rainfall brackets, and 3 rainfall nozzles are evenly spaced on each rainfall bracket, for a total of 21 rainfall nozzles.

[0044] As another example, by using a high-pressure water pump and a DN100 water supply pipe, the water is pumped from the natural pool built at the bottom to the water supply tank located at the top of the platform. It takes 1.5 hours to quickly fill the water supply tank with a high-pressure water pump. The water supply tank is built with reinforced concrete structure, 8 meters long, 3.5 meters wide, 3 meters high, and has a full water storage capacity of 70 cubic meters. The water supply tank can meet the water supply needs during the large-scale experiment and ensure that the normal development of the experiment is not affected.

[0045] In some embodiments, the water pool is connected to the water supply tank through a second water pipeline, a second pressure pump is provided between the water supply tank and the second water pipeline, and a second valve is provided on the second water pipeline.

[0046] It can be understood that the amount of seepage in the water pool and the height of the seepage water level can be controlled by controlling the opening of the second valve and the height of the water level in the water pool.

[0047] In some embodiments, the artificial rainfall and infiltration device also includes a monitoring system and a control system. The monitoring system includes a sensor module located at the bottom of the material box and cameras arranged at the four corners of the upper part of the material box; the control system includes a controller, and the controller is respectively connected to the nozzle, the first pressure pump, the first valve, the second pressure pump and the second valve.

[0048] Furthermore, the sensor module includes a pore water pressure sensor, model: JUL-PW28; a normal stress sensor, model: MK-003; and a ground vibration sensor, model: CCUBE.

[0049] The pore water pressure sensor is used to measure the pore water pressure in the soil inside the material box. Rainfall and / or seepage will increase the pore water pressure in the soil of the material box, thereby reducing the shear strength of the soil. By installing a pore water pressure sensor inside the material box, the changes in pore water pressure under the influence of factors such as rainfall and seepage can be monitored.

[0050] Normal stress sensors are effective tools for monitoring stability, and can monitor stress changes in rock and soil under the influence of self-weight, rainfall, seepage, etc. For example, during rainfall and / or seepage, rainwater seeps into the rock and soil of the material box, which increases the pore water pressure and reduces the effective normal stress. This change can be captured in real time through normal stress sensors and pore water pressure sensors. When the effective normal stress decreases to a certain extent, it may cause slope instability.

[0051] The ground vibration sensor can monitor the stress changes inside the landslide body under the action of external forces in real time. When the landslide body in the material box is in a stable state, the stress changes are relatively small and have certain regularities; when there are triggering factors that cause the landslide body to begin to lose stability, the stress will fluctuate abnormally, such as stress concentration and stress direction change. By analyzing these stress change data, we can understand the evolution of the mechanical state inside the sliding material box, which provides an important basis for studying the breeding and development process of landslides and revealing the mechanism of landslides. In addition, through the monitored ground vibration sensor data, we can analyze the changes in the vibration characteristics of the landslide body under different conditions. When the vibration characteristics of the landslide body change significantly, such as a sudden increase in vibration frequency and amplitude, we can combine the changes in other monitoring indicators (pore water pressure, normal stress, etc.) to determine the critical conditions for the landslide to transform into a debris flow.

[0052] The camera, model: DS-2CD3T86FWDV3-I3S, is used to record the experimental process and monitor the changes in the slope in the material box and the entire process of the landslide turning into a debris flow, including the deformation of the slope, the generation and development of cracks, how the landslide turns into a debris flow, and speed changes.

[0053] It can be understood that the monitoring system and control system integrate various aspects and levels of contents such as experimental monitoring, rainfall control, data measurement and collection during the simulated rainfall experiment into the control room of the top platform to achieve the goal of automated and intelligent artificial rainfall.

[0054] See also Figure 1 In some embodiments, a water collecting tank is provided at the bottom of the tank. It can be understood that the sensor module is located in the water collecting tank.

[0055] See also Figure 5 and Figure 6 In some embodiments, the top of the gate is hinged to the material box, and the bottom of the gate is provided with an automatic locking mechanism; the gate also includes a power device, and the power device is connected to the gate through a wire rope.

[0056] It is understandable that the gate is subject to a greater lateral pressure from the clean water or water-soil mixture behind it, and it is necessary to ensure that the gate is water-tight before it is opened.

[0057] Exemplarily, the power equipment is used for opening and closing the gate, and the power equipment is a high-power high-speed winch-type gate opener with a main motor power of 250KW, a rated gate opening force of 2×125KN, and a rated rope speed of 63 meters per minute.

[0058] Exemplarily, the volume of the water-soil mixture contained in the material box is 500 cubic meters.

[0059] In the present application, soil and water are loaded in the material box, and the "water-tightness" in a "high stress" environment can be met through the gate and the automatic locking mechanism; the automatic locking mechanism can automatically control the rapid opening to meet the "instantaneous opening" requirement of the gate angle exceeding 45° within 5 seconds; the super-heavy gate of the present application can withstand the lateral pressure caused by clean water or water-soil mixture materials, and at the same time, the horizontal extrusion force generated when the automatic locking mechanism is locked makes the gate water seal reach the designed compression amount, thereby satisfying the sealing effect when the water or water-soil mixture generates lateral pressure. In addition, by shortening the time difference between the opening of the automatic locking mechanism and the starting of the power equipment, the motor of the power equipment can be quickly intervened, which in disguise reduces the time that the automatic locking mechanism of the gate is acted upon by hydrostatic pressure or soil pressure after retraction, thereby achieving the purpose of instantaneous release of materials, and can completely realize instantaneous release of materials.

[0060] See also Figure 5 and Figure 6 In some embodiments, hinge seats are respectively provided on both sides of the top of the gate, and steel wire ropes are respectively provided on both sides of the bottom of the gate, and each of the steel wire ropes is connected to the power equipment.

[0061] It can be understood that the support hinge seat is embedded in both sides of the large concrete water tank through embedded parts.

[0062] It can also be understood that the winch-type gate hoist pulls the wire rope to provide power so that the gate can rotate around the top support hinge seat to open.

[0063] In some embodiments, a bracket is provided above the gate, two fixed pulleys are fixed on the bracket, and each of the steel wire ropes passes around the corresponding fixed pulley and is connected to the power device.

[0064] Furthermore, a pressure sensor is provided at the fulcrum of each fixed pulley.

[0065] Please refer to 5. Figure 6 , Fig. 9 and Fig.10 In some embodiments, the automatic locking mechanism includes a locking groove located at the bottom of the gate, a latch matching the locking groove, a hydraulic pump connected to the upper part of the latch, and an oil pump is also provided on one side of the upper part of the material box, and the hydraulic pump is connected to the oil pump.

[0066] Furthermore, the gate also includes an electronic control unit, which is electrically connected to the power equipment, the pressure sensor, the hydraulic pump and the oil pump respectively.

[0067] Furthermore, the latch is wedge-shaped, and the locking groove matches the latch.

[0068] It can be understood that the electronic control unit is a conventional control device in the art and will not be described in detail here.

[0069] It can be understood that when the gate is opened or closed, the pressure value at the fulcrum can be monitored by the pressure sensor to determine the opening and closing angle of the gate; when the gate is opening, the pin is first retracted into place and the gate is unlocked, and then the power equipment (winch-type gate opener) quickly intervenes to wind up the wire rope and pull up the gate; when the pressure sensor value exceeds the set maximum value, the motor of the winch-type gate opener stops working to protect the equipment; a high-precision photoelectric encoder is provided at the end of the drum of the winch-type gate opener, which can dynamically control the opening angle of the gate and automatically stop when the gate is opened to the maximum opening and closing angle; in order to further ensure the safety of the rapid opening of the gate, a limit switch is set at the support hinge position. Once the encoder fails, the limit switch will play a role in limit stop protection.

[0070] It can be understood that during the loading process, the gate is closed, and the two hydraulic cylinders inside drive the wedge-shaped pin to insert into the bottom locking groove. The horizontal extrusion force generated by the wedge-shaped locking makes the gate water seal reach the designed compression amount, thereby satisfying the sealing effect when the water or water-soil mixture generates lateral pressure.

[0071] See also Figure 7 and Figure 8 In some embodiments, the gate includes a main frame and a panel welded to the main frame; the main frame includes I-shaped side beams on both sides, a plurality of I-shaped side beams located between the I-shaped side beams, Π The main beam and the bottom beam are arranged at the bottom of the I-shaped side beam. Π I-shaped short beams are laid between the main beams.

[0072] For example, the height of the I-shaped side beam is 1500 mm, the panel is made of 14 mm thick steel plate, and the bottom beam adopts a reinforced box structure to facilitate the arrangement of the automatic locking mechanism.

[0073] It can be understood that the special design of the overall gate meets the strength and rigidity requirements, and the overall deadweight is controlled at about 40 tons. The deadweight is reduced as much as possible while meeting the stress conditions, and it is a heavy-duty flip gate.

[0074] In some embodiments, a water pool is disposed on one side of the material box, and a plurality of rows of through holes are disposed at a portion of the material box adjacent to the water pool.

[0075] In some embodiments, the bottom of the material box is inclined, and the gate is located on the side of the material box with a lower inclination.

[0076] Working process: When the gate is closed, it is not easy to close tightly due to the existence of lateral pressure. Therefore, two rectangular square holes with a length, width and height of 0.3×0.3×0.5m are reserved at the bottom of the gate, namely the locking grooves. A hydraulic pump support rod is installed above the square hole. The bottom of the support rod is connected to the pin. When the gate is closed (the rotation angle is 0), the rotation angle can be detected by the reading of the pressure sensor on the top to determine the opening and closing angle of the gate. The greater the pressure value of the hydraulic pump, the deeper the depth of the connected pin inserted into the locking groove. The pressure value can be controlled by the electronic control unit to realize the control of the depth of the pin. The pin can be used with the prefabricated locking groove to solve the leakage problem under high stress. When the gate needs to be opened, the electronic control unit first needs to reduce the pressure value of the hydraulic pump to retract the bolt. When it retracts to a position flush with the bottom step of the gate (i.e., just pulled out of the prefabricated square hole), the electronic control unit immediately turns on the motor of the winch hoist, and the wire rope connected to the motor will be tightened, changing the direction of force through the fixed pulley device to lift the gate; when the gate opening and closing angle reaches 45 degrees, the motor stops working and maintains the current torque value to stabilize the gate at a 45-degree opening and closing angle. When the gate needs to be closed, the motor restarts and slowly releases the gate. When the gate opening and closing angle returns to 0 degrees, the motor will re-pressurize the hydraulic pump to reinsert the bolt into the prefabricated square hole to complete the pressurization and fixation to prevent water leakage after the water tank is filled with water.

[0077] The embodiments of the present invention are described in detail above. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
