Description

Technical Field

[0001] This invention relates to the field of substation technology, and in particular to a seepage drainage wall and a method for detecting soil erosion. Background Technology

[0002] With rapid economic development, electricity demand is increasing year by year, forcing power grid companies to build more power supply and distribution facilities. As a result, the number of substations is increasing. On the other hand, the number of electricity-consuming enterprises is also increasing rapidly, requiring more land for construction. Since electricity-consuming enterprises in various industries need to be built and developed in concentrated areas, but substations can meet their construction needs as long as there is enough land, the construction sites of power system substations are often located at the edges of ditches, rivers, and mountains. The backfilling of construction sites is extensive, and the construction period is short. After the substation is put into operation, due to insufficient compaction, fine sand and soil are washed away by the natural outflow of water, resulting in cavities inside the site and frequent settlement, which seriously threatens the safe operation of power facilities within the substation.

[0003] In existing technologies, the drainage consolidation method is used for treatment. However, this method has a significant impact on buildings and structures within a certain range around the site, often leading to tensile failure or instability due to uneven settlement. The impact of the drainage consolidation method on surrounding buildings and structures when treating soft soil foundations is mainly due to two reasons: First, the existence of a hydraulic gradient between the inside and outside of the site during the foundation treatment process creates seepage and uneven settlement, which can cause underground pipelines to crack and fail. Second, the soil is compressed during the foundation treatment process, disrupting the balance of earth pressure inside and outside the treatment area. The resulting earth pressure difference leads to instability of buildings and structures. Therefore, using this method alone has certain drawbacks.

[0004] Vacuum surcharge preloading is employed as a treatment method. This method demonstrates significant effectiveness in strengthening a site through vacuum preloading, allowing for a single, staged process without the need for tiered loading. The reinforcement effect is uniform, and the entire site is treated simultaneously. Applying soil surcharge loads on top of vacuum preloading further enhances the foundation's bearing capacity and eliminates post-construction settlement. Utilizing a combination of vacuum and surcharge preloading to reinforce soft soil foundations allows for the reuse of surcharge loads in many projects. The surcharge load is fast, stable, and accelerates construction settlement while shortening the construction period. However, due to excavations for water supply and drainage pipeline installation, equipment foundation construction, and grounding grid construction, insufficient compaction in the backfilled areas can lead to the outflow of fine sand and soil under water seepage, creating uneven settlement zones. Therefore, using this method alone also has certain drawbacks.

[0005] Therefore, there is an urgent need for a permeable drainage wall and a method for detecting soil erosion to solve the aforementioned problems. Summary of the Invention

[0006] Based on the above, the purpose of this invention is to provide a method for detecting permeable drainage walls and soil erosion. Operators can quickly identify abnormal locations and take corresponding measures by collecting information, thereby preventing soil erosion, preventing uneven settlement, and improving the bearing capacity of the foundation.

[0048] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

They are used only for ease of description and simplification of operation, and 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. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0052] like Figures 1-4 As shown, this embodiment provides a permeable drainage wall, which includes a drainage wall 1, a permeable board 2, and a drainage monitoring device.

[0053] Specifically, the drainage wall 1 has multiple mounting cavities 11 arranged along a first direction, which is the height direction of the drainage wall 1. Each mounting cavity 11 has a through hole 14 along its sidewall in a second direction, which is perpendicular to the sidewall of the drainage wall 1. A permeable plate 2 is installed within the mounting cavity 11. A first water level test hole 21 and a second water level test hole 22 are provided, penetrating the permeable plate 2 along the first direction and spaced apart along the second direction. The drainage monitoring device includes a water level acquisition module, which is used to acquire the first water level 211 in the first water level test hole 21 and the second water level 221 in the second water level test hole 22. In this embodiment, the first direction is Z, and the second direction is X.

[0054] The substation is enclosed by a permeable drainage wall. A permeable plate 2 is installed in the installation cavity 11 of the drainage wall 1. Groundwater on the inside and outside of the drainage wall 1 can flow between each other through the through hole 14 and the permeable plate 2. The water level acquisition module collects the first water level 211 in the first water level test hole 21 and the second water level 221 in the second water level test hole 22. By comparing the height information of the first water level 211 and the second water level 221, the groundwater pressure on the inside and outside of the drainage wall 1 can be determined. When the groundwater pressure on the inside and outside of the drainage wall 1 is abnormal, the operator can quickly determine the abnormal location and take corresponding measures based on the collected information, thereby preventing soil erosion, preventing uneven settlement, and improving the bearing capacity of the foundation.

[0055] Furthermore, the first water level test hole 21 is located on the side closer to the inner side of the drainage wall 1, while the second water level test hole 22 is located on the side closer to the outer side of the drainage wall 1. The water level acquisition module includes two water level monitoring sensors, located in the first water level test hole 21 and the second water level test hole 22, respectively. By comparing the height of the first water level 211 in the first water level test hole 21 and the second water level 221 in the second water level test hole 22, the groundwater infiltration rate and the rate of rise and fall in water level are determined. This allows for the determination of the water level differences or changes in groundwater pressure on both sides of the drainage wall, further identifying dangerous areas. Figure 4 As shown, when the first water level 211 is greater than the second water level 221, it can be determined that the groundwater pressure inside the seepage drainage wall is greater than the groundwater pressure outside the seepage drainage wall, and groundwater seeps from the inside to the outside; conversely, as... Figure 11 As shown, when the height of the first water level 211 is less than that of the second water level 221, it can be determined that the groundwater pressure inside the seepage drainage wall is less than the groundwater pressure outside the seepage drainage wall, and the groundwater seeps in from the outside to the inside.

[0056] Preferably, such as Figures 4-6 As shown, the permeable plate 2 includes multiple sub-permeable plates 23, which are stacked along a first direction. One end of each sub-permeable plate 23 has a first protrusion 231, and the other end has a first groove 232. The first protrusion 231 of one adjacent sub-permeable plate 23 is embedded within the first groove 232 of another sub-permeable plate 23, optimizing the planar structure between the sub-permeable plates 23 into an embedded structure. This achieves vertical splicing of the sub-permeable plates 23 and reduces the flow of water and soil between the permeable drainage walls, thereby improving soil and water conservation capacity. Furthermore, since the permeable plate 2 is composed of multiple sub-permeable plates 23, the number of sub-permeable plates 23 can be adaptively adjusted according to the depth of the installation cavity 11.

[0057] More preferably, such as Figure 2 , Figure 6 and Figure 12 As shown, one of the two ends of the permeable plate 2 along the second direction and the side wall of the mounting cavity 11 along the second direction is provided with a second protrusion 12, and the other is provided with a second groove 24, with the second protrusion 12 embedded in the second groove 24; one of the bottom wall of the permeable plate 2 and the bottom wall of the mounting cavity 11 is provided with a third protrusion, and the other is provided with a third groove 13, with the third protrusion embedded in the third groove 13. Similarly, optimizing the planar structure between the permeable plate 2 and the mounting cavity 11 into an embedded structure can reduce the amount of water and soil flowing between the permeable drainage wall, thereby improving the water and soil conservation capacity. In this embodiment, the mounting cavity 11 is provided with a second protrusion 12, and the permeable plate 2 is provided with a second groove 24. In this embodiment, the mounting cavity 11 is provided with a third groove 13, and the permeable plate 2 is provided with a third protrusion.

[0058] Preferably, the outer side of the permeable board 2 is covered with a permeable cloth, and the upper, lower, left and right surfaces of the permeable board 2 are all provided with permeable cloth, which improves the water permeability and sealing between structural components and has a buffering effect, improves the ability to prevent natural outflow from carrying away fine sand and soil, and improves the ability to prevent the occurrence of cavities inside the site.

[0059] Among them, the first protrusion 231, the second protrusion 12 and the third protrusion are all double protrusion structures, and the first groove 232, the second groove 24 and the third groove 13 are all double groove structures, which improves the connection stability and prevents obvious water flow from appearing on the contact surface.

[0060] In this embodiment, as Figure 7 and Figure 8 As shown, there are multiple drainage walls 1, which are stacked along the first direction. Adjacent drainage walls 1 are connected by a first grouting zone 4. The first water level test hole 21 and the second water level test hole 22 penetrate the first grouting zone 4. The permeable drainage walls are arranged in a multi-layer stacked manner. Each layer is connected by secondary grouting with reinforced concrete to form the first grouting zone 4, so as to achieve layered water pressure balance and layered permeable drainage.

[0061] Since there are multiple drainage walls 1, each drainage wall 1 or part of the drainage wall 1 can collect information on the first water level 211 and the second water level 221 through the drainage monitoring device, thereby understanding the groundwater pressure information inside and outside the drainage wall 1 at any location outside the substation. Operators can quickly identify abnormal locations and take corresponding measures through the collected information, thereby preventing soil erosion, preventing uneven settlement, and improving the bearing capacity of the foundation.

[0062] Preferably, the sidewall of the bottom drainage wall 1 is conical, so the drainage wall 1 can withstand a large shear force. The size of the conical surface 16 of the bottom drainage wall 1 is determined according to the specific burial depth below zero meters.

[0063] Furthermore, such as Figure 9 As shown, the drainage wall 1 is provided with multiple square holes 18, which are arranged in a ring around the rotating cavity. When multiple layers of drainage walls 1 are stacked, the square holes 18 are filled with reinforced concrete for secondary grouting and reinforcement cages, so as to meet the structural stress requirements when the overall height of the permeable drainage wall is increased. Among them, when the drainage walls 1 are stacked along the first direction, the square holes 18 penetrate through the other drainage walls 1 except for the bottom drainage wall 1, and part of them are located in the bottom drainage wall 1.

[0064] like Figure 9 and Figure 10 In this embodiment, there are multiple drainage walls 1, which are spliced ​​together along a third direction. The first direction, the second direction, and the third direction are perpendicular to each other. In this embodiment, the third direction is Y. Adjacent drainage walls 1 are connected by a second grouting area, achieving infinite splicing in the horizontal direction. Adjacent drainage walls 1 are spaced apart, and each drainage wall 1 has a fourth groove 15 at both ends. The gaps between adjacent drainage walls 1 and the fourth grooves 15 are filled with reinforced concrete using secondary grouting, and a steel cage forms a second grouting area, achieving connection between adjacent drainage walls 1. This results in high structural strength. The second groove 24 improves the connection strength between the second grouting area and the drainage wall 1, while also achieving regional water pressure balance and regional infiltration drainage. It should be noted that the drainage walls 1 located at the corners are L-shaped, enabling reversible splicing of the drainage walls 1.

[0065] It should be noted that the permeable drainage wall can be prefabricated in the factory or cast on site, and the internal steel reinforcement cage needs to be determined according to the stress calculation of the specific project.

[0066] Preferably, such as Figure 1 As shown, the drainage wall 1 has multiple wiring holes 17 on its sidewall along the second direction, and plugs can be detachably installed inside the wiring holes 17. When wiring is required, the wiring holes 17 can be selected and the plugs removed as needed; when wiring is not required, the plugs are installed in the wiring holes 17 to seal them and prevent water and soil from flowing inside them. More preferably, the multiple wiring holes 17 are arranged vertically, which is beneficial for use with grounding grids at different burial depths.

[0067] Furthermore, the substation is equipped with a "Substation Groundwater Organized Infiltration and Drainage Monitoring System," which consists of a "Drainage Monitoring Device" and a "Substation Groundwater Organized Infiltration and Drainage Monitoring System Host." The "Drainage Monitoring Device" is connected to the "Substation Groundwater Organized Infiltration and Drainage Monitoring System Host" via Ethernet to achieve two-way information exchange. The "Substation Groundwater Organized Infiltration and Drainage Monitoring System Host" can be connected to higher-level or other monitoring systems via an independent Ethernet interface to achieve information sharing or centralized monitoring.

[0068] The drainage monitoring device also includes an environmental acquisition module, a synchronization interface module, a communication interface module, and an alarm output module, all electrically connected to the water level acquisition module. The environmental acquisition module detects whether it is raining; the synchronization interface module synchronizes the acquisition time of the water level acquisition module and calculates the acquired information synchronously; the alarm output module sends alarm information to the communication interface module, which then transmits the alarm signal to the operator. It should be noted that the water level acquisition module, environmental acquisition module, synchronization interface module, communication interface module, and alarm output module are all electrically connected to the analysis and control unit. The functions of each module are mature technologies in the existing field and will not be elaborated further. The electrical connection can be via cable or via a secure wireless signal such as reliable Wi-Fi; these connection methods are standard in the control field and require no further explanation.

[0069] This embodiment also provides a method for detecting soil erosion, using the aforementioned permeable drainage wall; the method for detecting soil erosion includes the following steps:

[0070] like Figure 4 and Figure 11 As shown, the water level 211 in the first water level test hole 21 and the second water level 221 in the second water level test hole 22 are detected by the water level acquisition module. The abnormality may be caused by the low ground pressure inside the drainage wall 1 at the abnormal point, which may indicate that excavation or groundwater extraction is underway. This needs to be checked and confirmed.

[0071] If both the first water level 211 and the second water level 221 are higher than the upper limit water level, the first alarm signal will be issued. The cause of the abnormality may be that there are heavy objects piled up on both the inner and outer sides of the drainage wall 1 at the abnormal point, heavy vehicles have been parked for a long time, or there is local leakage. It needs to be checked and determined.

[0072] If both the first water level 211 and the second water level 221 are lower than the lower limit water level, a second alarm signal will be issued. The cause of the abnormality may be that the ground pressure on the inner and outer sides of the drainage wall 1 at the abnormal point is too low, and there may be excavation or groundwater extraction work in progress. It needs to be checked and confirmed.

[0073] If both the first water level 211 and the second water level 221 rise, and the first water level 211 is higher than the second water level 221, a third alarm signal will be issued. When the third alarm signal is received, the cause of the abnormality may be that there are heavy objects piled up on the inside of the drainage wall 1 at the abnormal point, heavy vehicles have been parked for a long time, or there is local leakage. It needs to be checked and determined.

[0074] If both the first water level 211 and the second water level 221 rise, and the first water level 211 is lower than the second water level 221, a fourth alarm signal will be issued. The cause of the abnormality may be that there are heavy objects piled up on the outside of the drainage wall 1 at the abnormal point, heavy vehicles have been parked for a long time, or there is local leakage. It needs to be checked and determined.

[0075] If both the first water level 211 and the second water level 221 decrease, and the first water level 211 is higher than the second water level 221, a fifth alarm signal will be issued. The cause of the abnormality may be that the ground pressure outside the drainage wall 1 at the abnormal point is too low, and there may be excavation or groundwater extraction work in progress. It is necessary to check and confirm to prevent large-scale groundwater and soil from moving into or out of the station and causing adverse effects on the substation.

[0076] If both the first water level 211 and the second water level 221 decrease, and the first water level 211 is lower than the second water level 221, a sixth alarm signal will be issued. The cause of the abnormality may be that the ground pressure inside the drainage wall 1 at the abnormal point is too low, and there may be excavation or groundwater extraction work in progress. It needs to be checked and confirmed.

[0077] It should be noted that the above-mentioned information on the first water level 211 and the second water level 221, as well as the analysis of the causes of the anomalies, are based on the measurement and analysis results when the first water level 211 and the second water level 221 tend to stabilize after no rain or after a period of time following rain.

[0078] If the environmental acquisition module detects external rain and the water level inside the drainage wall 1 is higher than the water level outside, then when the first water level 211 is higher than the second water level 221, the discharge of groundwater outward within the substation area is a normal drainage process. If the first water level 211 is lower than the second water level 221, this is an abnormal point and needs to be checked and confirmed.

[0079] If the environmental acquisition module detects external rain and the water level inside the drainage wall 1 is lower than the water level outside, the infiltration and drainage of groundwater from outside the substation when the second water level 221 is higher than the first water level 211 is a normal drainage process, but it should be monitored. If the second water level 221 is lower than the first water level 211, this is an abnormal point and needs to be checked and confirmed.

[0080] Furthermore, the water level acquisition module acquires the first water level 211 and the second water level 221 of multiple drainage walls 1 respectively. The water level at each acquisition point can be set with an upper limit alarm value and a lower limit alarm value in the drainage monitoring device. When the measured values ​​of the first water level 211 and the second water level 221 are higher than the upper limit alarm value or lower than the lower limit alarm value, an alarm signal is automatically issued. On the one hand, it outputs an "abnormal alarm output in the substation area" alarm signal, and on the other hand, it sends the corresponding upper limit alarm value or lower limit alarm value alarm signal of the acquisition point to the "substation groundwater organized seepage drainage monitoring system host" via the Ethernet interface.

[0081] When the "Substation Groundwater Organized Infiltration Drainage Monitoring System" monitors the first water level 211 and the second water level 221 of the infiltration drainage wall through the "Drainage Monitoring Device", the "Substation Groundwater Organized Infiltration Drainage Monitoring System" can automatically generate a real-time water level change curve, plot the dynamic curve of water level change at that point on the monitoring host, and issue an alarm signal for abnormal water level change and an abnormal area or abnormal point signal based on the collected water level being higher than the set upper limit or lower than the set lower limit.

[0082] The "Substation Groundwater Organized Infiltration Drainage Monitoring System" monitors the real-time water level changes at a specific location within the substation using the infiltration drainage wall. It plots the dynamic water level change curve at that point on the monitoring host. Simultaneously, based on the real-time water level change curve, it collects data on "temperature," "humidity," "rainfall," and "light intensity" within the substation area. The system plots the relationship between water level at any point and these parameters, displaying the positive and negative correlations between evaporation trends and water level. If an abnormal negative correlation (i.e., evaporation) is detected, the system alerts maintenance personnel.

[0083] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
