Abstract
Description
Technical Field
[0001] This application relates to the field of underground drainage pipeline technology, and in particular to a simulation platform for the operation and destruction of underground drainage pipelines. Background Technology
[0002] As a vast asset, underground drainage pipes have long suffered from insufficient research regarding their service life, pipe material design, and construction methods, especially regarding their performance and damage under earthquake conditions. This is due to two main reasons: firstly, drainage pipes generally have a long lifespan, requiring a lengthy research cycle; and secondly, the lack of a suitable simulation platform for easily observing and adjusting various variables, including seismic waveforms and intensity. While some vibration platforms are now used in laboratories to simulate the performance and damage of bridges and other structures under earthquakes, their application in the research of underground drainage pipes remains lacking.
[0003] Underground pipeline ruptures during earthquakes can trigger a chain reaction, including the leakage of toxic substances (such as chemical plant wastewater) and road collapses. Simulating the response of damaged pipelines under seismic impact (e.g., crack propagation rate, leakage threshold) can provide a scientific basis for targeted reinforcement, avoiding the waste of resources caused by indiscriminate replacement. Traditional design standards rely on theoretical calculations and lack data support on material fatigue and soil-pipe coupling failure under real earthquake conditions; therefore, experimental systems are urgently needed to verify the dynamic response characteristics of pipelines. Utility Model Content
[0004] This invention provides a simulation platform for the operation and damage of underground drainage pipes, so as to at least solve the above-mentioned technical problems existing in the prior art.
[0005] According to one aspect of this application, a simulation platform for the operation and failure of underground drainage pipes is provided. The simulation platform includes: an earthquake simulation device, an environmental simulation unit, a drainage pipe as the monitoring object, and a water circulation system. The earthquake simulation device is used to simulate vibrations caused by earthquakes; the environmental simulation unit is disposed on the earthquake simulation device to simulate the underground environment where the drainage pipe is buried; the drainage pipe, as the experimental monitoring object, is buried in the environmental simulation unit; the water circulation system is used to provide circulating water to the drainage pipe; and at least one sensor is disposed on the drainage pipe for monitoring the drainage pipe.
[0006] This patent simulates drainage pipes of various materials actually buried in the ground. All burial conditions are simulated in real-world scenarios, including backfill and bedding materials, soil composition, and groundwater properties. A water circulation system simulates the wear and damage caused by sewage, corrosive gases, and erosion under normal operating conditions. This data can guide the estimation of the lifespan of underground drainage pipes, and guide inspection plans and maintenance activities. Simultaneously, adjusting the composition, temperature, and flow rate parameters of rainwater and sewage can simulate the long-term performance of the pipes in a shorter time. During seismic simulation experiments on drainage pipes, the seismic simulation equipment can be driven to vibrate, simulating real earthquake conditions. The vibration platform allows for observation of the damage patterns and weak points of underground drainage pipes of various materials under seismic conditions. The water circulation system is simultaneously activated to realistically simulate water flow within the drainage pipes. In this scenario, the drainage pipes can be monitored, such as the pressure they bear, changes in harmful gases and liquid levels. This allows for experimental verification of the dynamic response characteristics of underground drainage pipes during earthquakes, providing a scientific basis for targeted reinforcement of underground drainage pipes, guiding design, and optimizing pipe material selection. In addition, this platform can also optimize and guide construction methods by analyzing the performance of different construction methods, such as the material and thickness of the subbase and backfill materials, under operational and seismic conditions.

[0015] refer to Figure 1 and Figure 2 As shown, this application provides a simulation platform for the operation and failure of underground drainage pipes. (Reference) Figure 1 and Figure 2 As shown, the simulation platform includes: an earthquake simulation device 100, an environmental simulation unit 200, a drainage pipe 300 as the monitoring object, and a water circulation system 400. The earthquake simulation device 100 is used to simulate vibrations caused by earthquakes; the environmental simulation unit 200 is installed on the earthquake simulation device 100 to simulate the underground environment where the drainage pipe 300 is buried; the drainage pipe 300, as the experimental monitoring object, is buried in the environmental simulation unit 200; the water circulation system 400 provides circulating water to the drainage pipe 300; and at least one sensor 501-503 is installed on the drainage pipe 300 for monitoring the drainage pipe 300.
[0016] Therefore, this patent simulates drainage pipes of various materials actually buried in the soil. All burial conditions simulate real-world scenarios, including backfill and bedding materials, soil composition, and groundwater properties. The water circulation system 400 simulates the wear and damage caused by sewage, corrosive gases, and erosion under normal operating conditions. This data can guide the estimation of the underground drainage pipe's lifespan, and guide inspection plans and maintenance activities. Simultaneously, adjusting the composition, temperature, and flow rate parameters of rainwater and sewage allows for the simulation of long-term pipe performance in a shorter time. During seismic simulation of the drainage pipe 300, the seismic simulation device 100 can be driven to vibrate, simulating real earthquake conditions. This allows for the observation of damage patterns and weak points of underground drainage pipes of various materials through the simulated seismic conditions on the vibration platform. Simultaneously, the water circulation system 400 is activated to realistically simulate water flow within the drainage pipe. In this scenario, the drainage pipe 300 can be monitored, for example, by monitoring the pressure exerted on it, changes in harmful gases and liquid levels within the pipe. This allows for experimental verification of the dynamic response characteristics of underground drainage pipes during earthquakes, providing a scientific basis for targeted reinforcement of underground drainage pipes, thereby guiding design and optimizing pipe material selection. Simultaneously, this platform can also optimize and guide construction methods by analyzing the performance of different construction methods, such as the material and thickness of the subbase and backfill materials, under operational and seismic conditions.
[0017] Furthermore, the materials used for drainage pipes 300 include commonly used pipe materials such as reinforced concrete pipes, PVC pipes, metal pipes, HDPE pipes, and fiberglass reinforced plastic pipes.
[0018] Optionally, the earthquake simulation device 100 includes: a platform 110; a vertical actuator 121 for driving the platform 110 to vibrate in the vertical direction; and a horizontal actuator 122 for driving the platform 110 to vibrate in the horizontal direction. Thus, the earthquake simulation device of this application can provide vibrations in both the vertical and horizontal directions, thereby enabling a more realistic simulation of earthquake conditions.
[0019] Optionally, the environmental simulation unit 200 includes: a first filler 211 surrounding the drainage pipe 300 to simulate the soil environment around the drainage pipe 300; and a second filler 212 surrounding the first filler 211. Preferably, this application first excavates an inverted trapezoidal trench along the extension direction of the drainage pipe 300 in the second filler 212, then places the drainage pipe 300 into the inverted trapezoidal trench and buries the first filler 211. After the first filler 211 fills the inverted trapezoidal trench, the second filler 212 is then filled. Thus, a... Figure 1 and Figure 2 The structure shown.
[0020] Optionally, the environmental simulation unit 200 includes a container 220 for accommodating a first filler 211 and a second filler 212, wherein the container 220 includes first sidewalls 221 and 222 arranged parallel to the drain pipe 300 and second sidewalls 223 and 224 arranged perpendicular to the drain pipe 300.
[0021] Optionally, the second sidewalls 223 and 224 are provided with openings 225 and 226 for exposing the ends of the drain pipe 300. The second sidewalls 223 and 224 are sealed and bonded to the outer edge of the drain pipe 300 at the locations of the openings 225 and 226. In this way, the ends of the drain pipe 300 can be exposed through the openings 225 and 226, facilitating the supply of water to the drain pipe 300 to simulate water circulation. Simultaneously, leakage of the first filler 211 from the openings 225 and 226 is prevented.
[0022] Optionally, at both ends of the drainage pipe 300, the inner edge of the drainage pipe 300 is sealed and bonded to transparent material plates 321 and 322. This allows observation of changes in water flow within the drainage pipe 300 during an earthquake through the transparent material plates 321 and 322.
[0023] Optionally, the water circulation system 400 includes a circulating water pump 410, an inlet pipe 421, and an outlet pipe 422. The inlet pipe 421 connects the circulating water pump 410 to one end of the drainage pipe 300, and the outlet pipe 422 connects to the other end of the drainage pipe 300. In this way, water can be continuously supplied to the drainage pipe 300 during earthquake simulation experiments.
[0024] Optionally, the transparent material plates 321 and 322 have openings at positions corresponding to the water inlet pipe 421 or the water outlet pipe 422. Preferably, the water inlet pipe 421 and the water outlet pipe 422 are sealed and adhered to the transparent material plate 321 or 322 at the corresponding openings to prevent water leakage.
[0025] Optionally, at least one sensor includes a gas sensor 501 and / or an ultrasonic level sensor 502 disposed within the drainage pipe 300. Thus, when sewage is injected into the drainage pipe 300 through the water circulation system 400, the concentration of harmful gases within the drainage pipe 300 can be monitored by the gas sensor 501. And when an earthquake is initiated...
[0026] Optionally, at least one sensor includes a pressure sensor array 503 laid on at least a portion of the outer surface of the drainage pipe 300. Thus, when driving the vertical actuator 121 and / or the horizontal actuator 122 to perform earthquake simulation, the pressure distribution on the outer surface of the drainage pipe 300 can be monitored by the pressure sensor array 503.
[0027] This patent simulates drainage pipes of various materials actually buried in the ground. All burial conditions are simulated in real-world scenarios, including backfill and bedding materials, soil composition, and groundwater properties. A water circulation system simulates the wear and damage caused by sewage, corrosive gases, and erosion under normal operating conditions. This data can guide the estimation of the lifespan of underground drainage pipes, and guide inspection plans and maintenance activities. Simultaneously, adjusting the composition, temperature, and flow rate parameters of rainwater and sewage can simulate the long-term performance of the pipes in a shorter time. During seismic simulation experiments on drainage pipes, the seismic simulation equipment can be driven to vibrate, simulating real earthquake conditions. The vibration platform allows for observation of the damage patterns and weak points of underground drainage pipes of various materials under seismic conditions. The water circulation system is simultaneously activated to realistically simulate water flow within the drainage pipes. In this scenario, the drainage pipes can be monitored, such as the pressure they bear, changes in harmful gases and liquid levels. This allows for experimental verification of the dynamic response characteristics of underground drainage pipes during earthquakes, providing a scientific basis for targeted reinforcement of underground drainage pipes, guiding design, and optimizing pipe material selection. In addition, this platform can also optimize and guide construction methods by analyzing the performance of different construction methods, such as the material and thickness of the subbase and backfill materials, under operational and seismic conditions.

Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.
[0029] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.
[0031] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application.
