Abstract
Description
Technical Field
[0001] This application relates to the field of debris flow research and is an experimental system for simulating debris flow outbreaks and analyzing debris flow movement. Background Technology
[0002] The rapid development of highway and railway construction in Southwest China has led to a surge in the number of bridges. As a region prone to debris flows, simulating and analyzing debris flows to prevent their threat to engineering structures has become paramount. Analyzing debris flow at the site of an engineering project allows for the incorporation of influencing factors into the architectural design phase, enabling prevention and mitigation. However, debris flows are highly unpredictable, making real-time monitoring and data acquisition challenging and resulting in insufficient data for debris flow research. Previous indoor debris flow simulation systems were limited to fixed locations and were not universally applicable to different geological and geomorphological regions. This new system utilizes a modular structure, enabling rapid and efficient simulation of various debris flow scenarios. Furthermore, it allows for indoor debris flow simulation and analysis of movement characteristics, fundamentally solving the problem of limited data and enabling efficient acquisition of debris flow analysis data. Summary of the Invention
[0003] The purpose of this simulation system is to provide a method for simulating the occurrence of debris flows under different conditions indoors by adjusting various parameters, in order to solve problems such as the suddenness of debris flows, the difficulty in real-time monitoring and data collection, and the incompatibility of data from different regions.

[0005] 2. The water tank consists of a storage tank bottom plate 3, inclined trough I bottom plate 4, inclined trough II bottom plate 5, inclined trough III bottom plate 6, waste recycling tank bottom plate 7, and side plates installed on both sides of each bottom plate; a storage tank side plate 8, inclined trough I side plate 9, inclined trough II side plate 10, inclined trough III side plate 11, and waste recycling tank side plate 12. Each inclined trough has a handle at both ends, and the angle between the inclined troughs can be adjusted using brackets. The side plates are made of high-strength glass, ensuring safety and stability while also ensuring that the action camera can clearly capture the mudslide.
[0006] The simulated rainfall system includes a water tank 20, a water pump 21, an inlet pipe 22, an outlet pipe 23, and rain showers 29. The rain showers are mounted on a dedicated bracket with a water supply pipe running through it. The gaps between the shower heads 29 are small to ensure continuous simulated rainfall. The opening of the water tank 20 is located at the lower left of the entire tank and connects to the inlet pipe 22 of the water pump 21. The outlet pipe 23 connects to the water pump 21 and splits into two branches after a certain length to supply water to the rain showers 29.
[0007] 4. The debris flow induction system includes a hydraulic lifting platform 26, a hydraulic press 27, and a storage trough door lift 30. The hydraulic lifting platform 26 is aligned with the support frame to ensure a tight connection between the storage trough and the inclined channel. The storage trough door is made of high-strength glass for easy observation of the debris flow. The storage trough door lift 30 is responsible for opening and closing the door, and the hydraulic press 27 provides power to the entire hydraulic lifting platform 26.
[0008] 5. The waste recycling tank contains a waste mesh 28 made of fine steel wire. The mesh is located near the back of the simulated bridge pier and is at the same height as the side plate of the waste recycling tank. It can separate the flowing water and stones, making it convenient to recycle and reuse the waste after the experiment.
[0009] 6. Ordinary brackets: bracket I14, bracket II15, bracket III16 and hydraulic bracket 17, bracket roller 13. The bracket base is equipped with wheels to allow the bracket to be placed freely, and there is a brake to fix the bracket.
[0010] Working Principle: The entire impact process is visualized using a transparent water tank and debris flow. By adjusting the inclination, the entire evolution of debris flow impacting engineering structures at different inclinations can be simulated. By using different water-to-lithium ratios in the storage tank, the entire process of debris flow impacting engineering structures in different regions can be simulated. The monitoring device is used to monitor the entire process of debris flow released from the bottom plate of the storage tank impacting the bridge piers set on the bottom plate of inclined tank III. The waste recycling device ensures a clean and tidy experimental environment and allows for the recycling and reuse of experimental waste. This device provides an effective means for studying the impact of debris flows on engineering structures.
[0011] The beneficial effects of this invention are as follows:
[0012] (1) It can obtain a large amount of debris flow data from different regions, avoid the waste of a lot of manpower and resources in real-time monitoring, promote the in-depth development of debris flow research, promote the development of advanced technologies and methods, and thus improve the overall disaster prevention and mitigation capabilities.
[0013] (2) The simulation system can assess the probability of debris flow and its potential impact, helping governments and communities to develop scientific disaster prevention plans. Based on the simulation results, emergency supplies and teaching staff can be allocated rationally to ensure that resources can be quickly deployed when a disaster occurs.

[0024] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.
[0025] This equipment includes a pier device 1, a monitoring device 2 (front camera 18, side camera 19), a water tank, and a water tank support. The water tank consists of a storage tank bottom plate 3, an inclined trough I bottom plate 4, an inclined trough II bottom plate 5, an inclined trough III bottom plate 6, a waste recycling tank bottom plate 7, and side plates installed on both sides of each bottom plate (storage tank side plate 8, inclined trough I side plate 9, inclined trough II side plate 10, inclined trough III side plate 11, and waste recycling tank side plate 12). The storage tank bottom plate, inclined trough I bottom plate, inclined trough II bottom plate, inclined trough III bottom plate, and waste recycling tank bottom plate are sequentially and movably connected. The storage tank bottom plate also has a side plate on the side away from the other bottom plates to block debris flows. A waste net 28 is installed in the middle of the waste recycling tank. The support includes support rollers 13, support I 14, support II 15, support III 16, and a hydraulic support 17. The tilt angle of the inclined trough III bottom plate can be adjusted by the hydraulic support. The water tank 20, water pump 21, inlet pipe 22, outlet pipe 23, and rain shower 29 constitute a rainfall simulation system. Stress plates 24 and stress collectors 25 ensure real-time data transmission. The hydraulic lifting platform 26, hydraulic press 27, and storage silo door lift 30 ensure that the water-stone system can be activated at any desired height at any time.
[0026] Before simulating a debris flow, the prepared mud and stone mixture, tailored to the specific soil conditions and water-stone ratio, is stored in a storage tank. The condition of the hydraulic press 27 is checked, with particular attention to prevent any malfunctions that could lead to safety and economic losses during the experiment. The hydraulic press 27 then lifts the storage tank containing the mud and stone to the pre-calculated height. The ends of the inclined troughs I9, II10, and III11 are secured in the slots of the support frame. Based on the simulated terrain and slope, the hydraulic support is adjusted to ensure the angles between the three inclined troughs and the ground, as well as the angles between the inclined troughs, meet the required standards. The connection between the storage tank and inclined trough I9 is checked to ensure there are no gaps at the joint. Add sufficient water to the pool 20, then connect the pre-prepared long pipe 22 to the inlet of the water pump 21. Connect the outlet of the other end of the water pump 21 to the inlet pipe 23 of the rain shower 29 simulating rainfall in the test equipment. After connecting, check the sealing of the equipment connection to ensure there is no air leakage or unstable connection, in order to eliminate potential safety hazards and problems affecting the test results. Set up the detection equipment, with one high-speed camera 18 facing the inclined trough and another high-speed camera 19 placed on one side of the transparent side plate of the inclined trough, ensuring that both cameras can clearly capture the entire process of the debris flow. Turn on both cameras and set them to high-speed recording mode.
[0027] Finally, the simulated pier 1 stone column is placed at the edge of the junction of the bottom plate and groove of the inclined trough III11. Stress plates 24 are attached to the desired impact data locations, and the stress plates are connected to the computer 2. Pressure is applied to the stress plates to check if the computer collects stress data. The isolation net 28 is placed in the waste recycling trough beforehand, and its installation is checked for security. The waste recycling trough is connected to the inclined trough III11. After the test, the water and stones in the trough can be recycled into a container for easy repetition, reducing the impact of errors caused by the water-stone ratio. Finally, the rain shower 29 above the frame is turned on to simulate rainfall, and the storage tank is opened to allow water and stones to flow down the inclined trough. A high-speed camera is used to capture the movement characteristics of the debris flow. Data from the stress plates is recorded at the moment the debris flow impacts the pier. All stress data is compiled into a chart. After the flow ends, the waste is recycled and reused. The test is repeated multiple times to ensure data accuracy.
