Abstract
Description
Technical Field
[0001] The utility model relates to the field of testing devices, in particular to a device for testing the anti-seepage performance of self-expanding particles under a high water pressure loading environment. Background Art
[0002] In karst areas, groundwater dissolution is significant, karst conduits are highly developed, and aquifers exhibit strong heterogeneity. This strong heterogeneity is primarily manifested in the high permeability of the conduit area, while the permeability of the bedrock is extremely low, resulting in an uneven distribution of permeability. The heterogeneity of karst aquifers determines that the karst area is a fragile geological environment, and this vulnerability poses many problems for the hydrogeological environment. For example, pollutants can easily enter the groundwater through sinkholes and conduits in the karst area, causing groundwater pollution; or the material in the soluble rock itself is carried away by water due to dissolution, making it difficult to form soil, leading to soil erosion. Due to the special geological structure of karst landforms and cave areas, groundwater flows are often present, resulting in high groundwater levels and increased pressure from groundwater on the surface and underground structures. Therefore, underground anti-seepage issues have always been a focus of attention.
[0003] Traditional anti-seepage materials are easily damaged in highly pressurized water environments, making them difficult to meet anti-seepage requirements. Therefore, the use of self-expanding particles as a new anti-seepage material has been proposed for underground anti-seepage in karst and cave areas. Self-expanding particles have excellent anti-seepage properties. However, their applicability under highly pressurized water requires further research. In-depth research on the anti-seepage performance of self-expanding particles in high-pressure water environments will not only provide new ideas and solutions for underground anti-seepage in karst and cave areas, but also help promote technological innovation and development in underground engineering construction and enhance regional geological disaster prevention and control capabilities.

[0018] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0019] The specific implementation of the present invention is described in detail below with reference to specific embodiments.
[0020] An embodiment of the present invention provides a device for testing the anti-seepage performance of self-expanding particles under a high water pressure loading environment, and the device comprises: a sample loading barrel 1; a flow collecting and weighing assembly is provided at the bottom of the sample loading barrel 1, and the mass of the water flow can be collected by the flow collecting and weighing assembly; a water pressure control assembly is provided on one side of the sample loading barrel 1, and a constant and stable water pressure can be provided by the water pressure control assembly; wherein, the water pressure control assembly comprises a booster pump 2, and the output end of the booster pump 2 is connected to a four-way pipe 21, a water vapor exchange tank 22 is provided on one side of the booster pump 2, a water pipe 23 is connected to the outer bottom of the water vapor exchange tank 22, and the end of the water pipe 23 away from the water vapor exchange tank 22 is connected to the four-way pipe 21; a water supply assembly capable of providing a water source is provided on one side of the booster pump 2.
[0021] It should be noted that the sampling barrel 1 is the main test container for placing self-expanding particle samples. The flow collection and weighing assembly is located at the bottom of the sampling barrel, and is mainly used to collect the mass of water flowing through the sample to monitor the mass change of the water flow in real time, thereby evaluating the anti-seepage performance. The water pressure control assembly is responsible for providing constant water pressure to simulate a high water pressure environment. The key part of the water pressure control assembly is the booster pump 2, whose output end is connected to a four-way pipe 21, which can distribute the water flow to different outlets. The function of the water vapor exchange tank 22 is to regulate the bubble and gas content in the water flow to ensure the stability and consistency of the water flow during the test. The water pipe 1 23 connects the water vapor exchange tank 22 and the four-way pipe 21, and is responsible for transporting the treated water flow to the sampling barrel. The water supply assembly provides the water source required for the test.
[0022] In an embodiment of the present utility model, the flow collection and weighing assembly includes an acrylic water flow plate 3, and the acrylic water flow plate 3 is located at the bottom of the sample loading bucket 1, and brackets 31 are installed around the bottom of the acrylic water flow plate 3. A water flow hole 32 is provided on the acrylic water flow plate 3. The flow collection and weighing assembly also includes a water collecting box 33, and the water collecting box 33 is located below the acrylic water flow plate 3. An electronic scale 34 is provided at the bottom of the water collecting box 33.
[0023] It should be noted that the acrylic material has good transparency, which makes it easy to observe the water flow and facilitates the experimenter to monitor the water flow status in real time. The water hole 32 allows the water to flow smoothly, avoiding water blockage, and can effectively collect the water flowing through. The installation of the bracket 31 ensures the stability of the acrylic water plate 3, preventing deformation or tilting under high water pressure environments, and ensuring the accuracy and repeatability of the test. The water collection box 33 is responsible for collecting the water flowing out of the acrylic water plate 3, ensuring that all outflow water can be accurately recorded. The electronic scale 34 can accurately measure the water volume in the water collection box in real time, providing a reliable basis for subsequent data analysis.
[0024] In an embodiment of the present utility model, the water supply assembly includes a water tank 5, and the top of the water tank 5 is connected to water pipe 2 51, the end of water pipe 2 51 away from the water tank 5 is connected to the input end of the booster pump 2, and the top of the water tank 5 is connected to water pipe 3 52, and the end of water pipe 3 52 away from the water tank 5 is connected to the four-way pipe 21.
[0025] It should be noted that: the water tank 5, as the core part of the water supply component, can be connected to an external water source and is responsible for storing and providing the water required for the test. By setting up the water tank 5, it is possible to ensure that there is sufficient water supply during the test, and to avoid the accuracy and reliability of the test results being affected by insufficient water. The connection of water pipe 2 51 allows the water in the water tank 5 to be sucked in by the booster pump 2. The booster pump 2 pressurizes the water through its input end and delivers it to the sample barrel 1, ensuring the stability and constancy of the water pressure, thereby simulating a high water pressure environment during the test. The setting of water pipe 3 52 allows the water tank 5 to be effectively connected to the booster pump 2 and the four-way pipe 21. By adjusting the water level and water flow in the water tank 5, the water pressure control can be further optimized to ensure the precise regulation of the water pressure during the test to meet the needs of different experimental conditions.
[0026] In an embodiment of the present utility model, a water pipe 4 11 is connected to the top of the sample loading barrel 1, and the end of the water pipe 4 11 away from the sample loading barrel 1 is connected to the four-way pipe 21, and two water outlet pipes 12 are connected to the outside of the sample loading barrel 1, one of the water outlet pipes 12 is connected to a pore pressure sensor 13, and the other water outlet pipe 12 is connected to a valve 14.
[0027] It should be noted that: water pipe 4 11 connects the sample barrel 1 with the four-way pipe 21, so that the water flow in the sample barrel 1 can be effectively circulated and regulated with other components. It ensures that the water level in the sample barrel 1 can be controlled according to the experimental requirements, so as to maintain the required water flow rate and water level. The two outlet pipes 12 on the outside of the sample barrel 1 have different functions, and are used to connect the pore pressure sensor 13 and the valve 14 respectively. The outlet pipe 12 connected to the pore pressure sensor 13 is responsible for monitoring the pore water pressure in the sample barrel. The outlet pipe 12 connected to the valve 14 can control the release of water flow.
[0028] The operating principle of the self-expanding particle anti-seepage performance testing device under high water pressure loading is as follows: First, a sample barrel (1) is laid from bottom to top with large-grained stones, small-grained stones, and fine sand, followed by a specific ratio of self-expanding particles. The entire sample barrel (1) is immersed in water, allowing the water to overflow the barrel. The immersion time is 24 hours, ready for testing. Next, the entire experimental device is assembled, including a water vapor exchange tank (22), a booster pump (2), the sample barrel (1), and a flow collection and weighing assembly. The water vapor exchange tank (22) is connected to the booster pump (2). The booster pump (2) is connected to a water tank (5) at one end and to the sample barrel (1) at the other. The water vapor exchange tank (22) is first filled with water, and the booster pump (2) is connected to a power source. After the sample barrel (1) is filled with water, the valve (14) is closed. A water hole (32) is provided in the center of the acrylic water plate (3), allowing water to flow through the sample barrel (1) under sufficiently high water pressure. The water collection box (33) is placed on an electronic scale (34), which is reset to zero. Finally, after the test apparatus is assembled, conduct the experiment. First, open the valve of the water vapor exchange tank 22 and set the operating pressure of the booster pump 2 to 0.1 MPa. Observe the sample barrel 1 for leakage. If the anti-seepage effect of the sample barrel 1 is good, continue to increase the operating pressure of the stainless steel booster pump to 0.2, 0.3, 0.4, 0.5, and 0.6 MPa, and observe whether the sample barrel 1 leaks. If water flows out when a certain pressure is reached, record the flow rate in the water collection box 33 over a certain period of time. If the water collection box 33 leaks extensively, it indicates that the sample has been damaged.
[0029] The first three steps are a test case, that is, testing the anti-seepage performance of self-expanding particles under different water pressures. If it is necessary to observe the anti-seepage performance of self-expanding particles under different laying thicknesses, it is necessary to prepare self-expanding particle samples of different thicknesses, set certain water pressure conditions for permeability testing, and also observe the changes in flow rate and flow velocity to explore the effect of laying thickness on the anti-seepage performance of self-expanding particles. The test steps are roughly the same as the first three steps. The only difference is that the water pressure does not need to be changed, that is, the water pressure is constant.
[0030] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.
[0031] The above are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
