Description

Technical Field

[0001] This invention relates to a ground settlement detection device, and more specifically to a ground settlement detection device that can predict sinkholes by continuously detecting ground settlement, thereby preventing sinkholes from occurring in advance, and can improve durability and save costs due to its simple structure. Background Technology

[0002] Sinkholes are also known as collapses and are caused by natural factors such as geology, as well as human factors such as large-scale civil engineering projects or water pipe leaks, poor excavation, and groundwater outflow.

[0003] In addition, the increasing frequency of sinkholes in urban areas, leading to various accidents and casualties, has created growing anxiety about when and where sinkholes might occur.

[0004] In urban areas, most subsidence is caused by human factors such as leaks in water supply and drainage pipes. Therefore, various studies are currently being conducted on methods to detect such ground subsidence.

[0005] Existing methods for detecting land subsidence include methods such as directly excavating areas where land subsidence is expected or using the cone petrometer test (CPT). However, these methods require damaging the geological layer, cannot continuously and frequently detect land subsidence, and are inefficient in terms of time and cost.

[0006] In addition, non-destructive methods are currently being developed, including those utilizing ground-penetrating radar (GPR), ground-based interferometric synthetic aperture radar (GB-InSAR), airborne lasers, and infrared imagery. For example, Korean Patent Registration No. 10-1857961 discloses a sinkhole detection system utilizing infrared image analysis.

[0007] However, the problem with these methods is that they also cannot continuously and frequently detect ground subsidence, and because they must use radar and infrared, they are not only structurally complex, but also require separate image processing and analysis, making them inefficient in terms of time and cost.

[0008] In addition, the above methods may cause traffic inconvenience when detecting ground subsidence, require highly specialized personnel, and involve information that is difficult for ordinary people to access, so it is difficult to eliminate the anxiety about subsidence tunnels.

[0009] Furthermore, since existing equipment for detecting ground subsidence relies on vehicle movement, the actual detection is centered on the roadway, excluding pedestrian crossings from the detection priority. Summary of the Invention

[0010] The purpose of this invention is to provide a ground subsidence detection device that can predict subsidence holes by continuously detecting ground subsidence, thereby preventing the occurrence of subsidence holes in advance, and can improve durability and reduce costs through a simple structure.

[0011] The technical issues that this invention aims to address are not limited to those mentioned above. Those skilled in the art to which this invention pertains can clearly understand other technical issues not mentioned from the following description.

[0012] The present invention provides a ground subsidence detection device that does not use an additional power source, but instead uses a detection cone that descends due to gravity when a cavity occurs in the ground or descends due to ground movement when the ground moves, and light source reflection to display warning colors.

[0013] To address the above-mentioned issues, one embodiment of the present invention provides a ground subsidence detection device, characterized in that it comprises: a main body in the form of a pipe; a transparent cover attached to one end of the main body; a detection cone disposed at the other end of the main body and movable when a cavity occurs in the ground or when the ground moves; a display unit installed within the main body in connection with the detection cone and having one or more reflective surfaces with a warning color; and a connecting part connecting the detection cone and the display unit, wherein as the detection cone moves, the reflective surface is configured to face the transparent cover, thereby reflecting the warning color.

[0014] According to an embodiment, the display unit includes: a rotating shaft that is rotatably mounted within the main body; and a reflector that is mounted on the rotating shaft and has one or more reflective surfaces, and a connecting part that can connect the rotating shaft and the detection cone.

[0015] According to an embodiment, the reflector includes at least three reflective surfaces that form an angle with each other and have different warning colors. As the detector cone moves, the rotation axis and the reflector rotate together, and the at least three reflective surfaces can be sequentially opposite the transparent cover.

[0016] According to an embodiment, the display unit includes: a rotating shaft that is rotatably mounted within the main body; and a reflector that is wound around the rotating shaft and has one or more reflective surfaces, and a connecting part that can connect the reflector and the detector cone.

[0017] According to an embodiment, the display unit further includes an auxiliary rotating shaft, which is rotatably mounted inside the main body, and a reflector suspended between the rotating shaft and the auxiliary rotating shaft can be arranged in a configuration opposite to the transparent cover.

[0018] According to an embodiment, the reflector includes at least two reflective surfaces that are continuously formed and have different warning colors. As the detector cone moves, the reflector, which is wrapped around the rotation axis, unfolds, and the at least two reflective surfaces are sequentially opposite the transparent cover.

[0019] According to an embodiment, it also includes an auxiliary body, which is incorporated within the main body, and the transparent cover and display portion may be disposed within the auxiliary body.

[0020] According to an embodiment, it may also include: a flexible tube, the two ends of which are respectively connected to the inner surface of the body and the probe cone.

[0021] According to an embodiment, the main body is formed in a curved form, and the transparent cover at one end of the main body can be set at an angle relative to the direction of gravity.

[0022] According to an embodiment, the probe cone may be formed with multiple protrusions to improve adhesion to the ground.

[0023] According to the present invention, since the ground settlement detection device is fixedly installed after drilling holes in the paved ground, it can continuously detect ground settlement, that is, it can be detected at any time. Therefore, it can predict sinkholes, so that measures can be taken immediately to prevent sinkholes from occurring in advance.

[0024] In addition, without using an additional power source, the warning colors are displayed by a detection cone that descends when a cavity occurs in the ground or when the ground moves, and by the reflection of a light source. The simple structure can improve durability and save costs.

[0025] In addition, not only professionals, but also ordinary people who move or settle in the area where the ground subsidence detection device is installed can easily determine whether there is ground subsidence through the warning color, thus eliminating anxiety about subsidence. By reporting, the detection personnel can play a role, thereby saving manpower.

[0026] In addition, different warning colors can be displayed according to the depth of the cavities in the ground, so warnings can be issued in stages. Furthermore, by setting up multiple ground subsidence detection devices at certain intervals, the horizontal size and shape of the cavities can be inferred.

[0027] The effects of this invention are not limited to those described above, but should be understood to include all effects that can be inferred from the invention's composition as described in the detailed description of the invention or the patent claims. Attached Figure Description

[0037] Hereinafter, with reference to the accompanying drawings, a preferred embodiment of the ground subsidence detection device of the present invention will be described.

[0038] Furthermore, the terms used below are defined in consideration of the functionality of this invention and may vary depending on the intent or practice of the user or operator. The embodiments described below are not intended to limit the scope of the invention, but are merely exemplary of the constituent elements set forth in the claims of this invention.

[0039] To clearly illustrate the invention, irrelevant details have been omitted, and throughout the specification, identical or similar constituent elements are given the same reference numerals. Throughout the specification, when a part "includes" a certain constituent element, it means that, unless specifically stated otherwise, other constituent elements are not excluded, but rather may be included.

[0040] First, refer to Figures 1 to 5The ground subsidence detection device according to the first embodiment of the present invention will be described.

[0041] The ground subsidence detection device according to the first embodiment of the present invention may mainly include a main body 100, a transparent cover 200, a detection cone 300, a display part 400, and a connecting part 500.

[0042] The main body 100 is mounted on the pavement 10 and the ground 20, and is constructed in a tubular form. A transparent cover 200 is attached to the upper end of the main body 100 to allow for the identification of warning colors and to seal the interior of the main body 100. In this embodiment, a ground settlement detection device is shown mounted across the pavement 10 and the ground 20, but it is not limited to this and can be installed anywhere to detect ground settlement.

[0043] The probe cone 300 is disposed at the lower end of the body 100 so as to contact the ground. In this embodiment, the probe cone 300 is configured such that at least a portion of the lower end of the body 100 is exposed and embedded in the ground.

[0044] In order to display a warning color based on the movement of the detector cone 300, a display unit 400 is provided inside the main body 100, which is connected to the detector cone 300 and has one or more reflective surfaces displaying the warning color. The detector cone 300 and the display unit 400 are connected by a connecting part 500.

[0045] Specifically, in this embodiment, the display unit 400 includes: a rotation shaft 420 rotatably mounted within the main body 100; and a reflector 440 mounted on the rotation shaft 420, having one or more reflective surfaces. The reflector 440 includes a base surface 441 that does not constitute a reflective surface and three reflective surfaces 442, 443, and 444 with different warning colors. The base surface 441 and the three reflective surfaces 442, 443, and 444 are configured to form 90-degree angles with each other. For example, the three reflective surfaces 442, 443, and 444 may be composed of a green reflective surface 442, a yellow reflective surface 443, and a red reflective surface 444.

[0046] When the ground settlement detection device is first installed, the base surface 441 is installed opposite the transparent cover 200 and does not reflect external light sources in its basic state. The three reflective surfaces 442, 443, and 444 are configured such that, as the rotation axis 420 rotates, the green reflective surface 442, the yellow reflective surface 443, and the red reflective surface 444 are sequentially opposite the transparent cover 200.

[0047] However, it is not limited to this. According to the embodiment, the reflector 440 may also be configured to not include the base surface, but only the reflective surface. When the ground settlement detection device is installed for the first time, the reflective surface is installed opposite to the transparent cover 200.

[0048] The connecting part 500 connects the rotating shaft 420 and the probe cone 300. For this purpose, one end of the connecting part 500 is fixed to the rotating shaft 420 in a wound state, and the other end can be fixed to the probe cone 300.

[0049] The working principle of the ground subsidence detection device when a cavity occurs within 20 mm of the ground surface is explained below.

[0050] If a cavity occurs in the ground 20 that once supported the probe cone 300, the force supporting the probe cone 300 will disappear, and the probe cone 300 will fall due to gravity. As the probe cone 300 falls, the rotation axis 420 rotates through the connecting part 500, and at the same time, the reflector 440 will rotate together.

[0051] Therefore, in the initial state where the base surface 441 is configured opposite to the transparent cover 200, one of the three reflective surfaces 442, 443, and 444 is configured to be opposite to the transparent cover 200, thereby reflecting the warning color. Specifically, since the rotation angle of the reflector 440 varies depending on the descent depth of the detector cone 300, the warning color can be displayed in stages. In other words, the deeper the detector cone 300 descends, the greater the rotation angle of the reflector 440, such as... Figure 3 As shown, as the probe cone 300 descends deeper, the green reflective surface 442, the yellow reflective surface 443, and the red reflective surface 444 are sequentially positioned opposite the transparent cover 200, reflecting green, yellow, and red in that order. In the diagram, green is represented by a grid pattern, yellow by solid diagonal lines, and red by alternating solid and dashed diagonal lines. For example... Figure 3 The checkered arrows represent reflected green light, the solid diagonal arrows represent reflected yellow light, and the solid and dashed diagonal arrows represent reflected red light.

[0052] As described above, since the depth of the cavity can be detected based on the warning color, immediate action can be taken. At this time, various light sources can be used for the external light source reflecting the surface, such as solar energy, streetlights, car lights, and flashlights.

[0053] According to an embodiment, the ground subsidence detection device of the present invention may further include a flexible tube 600, the two ends of which are respectively connected to the inner surface of the main body 100 and the detection cone 300. Therefore, the flexible tube 600 can elongate along with the detection cone 300 as it descends, simultaneously protecting the interior of the main body 100 to prevent foreign matter from entering. Furthermore, the flexible tube 600 helps maintain a vertical state as the detection cone 300 descends, reducing errors in depth detection results or limiting the length of the flexible tube 600, thereby limiting the depth to which the detection cone 300 can descend. The flexible tube 600 may, for example, be formed of a stretchable material or a pleated tube.

[0054] like Figure 4 and Figure 5 As shown, when multiple ground subsidence detection devices of the present invention are set up at certain intervals, the location and extent of the cavity can be determined based on whether each ground subsidence detection device displays a warning color, i.e., the horizontal size of the cavity. Furthermore, the depth of the cavity can be detected by the warning colors of each ground subsidence detection device, thereby determining the approximate shape of the cavity.

[0055] The embodiment describes that when a cavity occurs within the ground 20, the force supporting the probe cone 300 disappears, and the probe cone 300 descends due to gravity. However, this is not the only possibility; the probe cone 300 may also descend due to ground movement. To address this, multiple protrusions can be formed on the probe cone 300 to increase adhesion to the ground 20.

[0056] Next, refer to Figure 6 The ground subsidence detection device according to the second embodiment of the present invention will be described.

[0057] The ground subsidence detection device according to a second embodiment of the present invention mainly includes a main body 1100, a transparent cover 1200, a detection cone 1300, a display unit 1400, a connecting part 1500, and a flexible tube 1600. Here, the configuration of the main body 1100, the transparent cover 1200, the detection cone 1300, and the flexible tube 1600 is similar to... Figure 1 The content observed is the same as that observed in the previous text, so detailed explanations have been omitted.

[0058] Specifically, in this embodiment, the display unit 1400 includes: a rotating shaft 1420, which is rotatably mounted within the main body 100; and a reflector 1440, which is wound around the rotating shaft 1420 and has one or more reflective surfaces. The reflector 1440 includes a base surface 1441 that does not constitute a reflection and three reflective surfaces 1442, 1443, and 1444 with different warning colors, wherein the base surface 1441 and the three reflective surfaces 1442, 1443, and 1444 are continuously connected. Similarly, the three reflective surfaces 1442, 1443, and 1444 may be composed of a green reflective surface 1442, a yellow reflective surface 1443, and a red reflective surface 1444.

[0059] When the ground settlement detection device is first installed, the base surface 1441 is installed opposite the transparent cover 1200 and does not reflect external light sources in its basic state. The three reflective surfaces 1442, 1443, and 1444 are configured as reflectors 1440 that can unfold with the rotation of the rotating shaft 1420, so that the green reflective surface 1442, the yellow reflective surface 1443, and the red reflective surface 1444 are sequentially opposite the transparent cover 1200.

[0060] However, it is not limited to this. According to the embodiment, the reflector 1440 may also be configured to not include the base surface, but only the reflective surface. When the ground settlement detection device is installed for the first time, the reflective surface is installed opposite to the transparent cover 1200.

[0061] The connecting part 1500 connects the reflector 1440 and the detector cone 1300. For this purpose, one end of the connecting part 1500 is fixed to the reflector 1440, and the other end can be fixed to the detector cone 1300.

[0062] The working principle of the ground subsidence detection device when a cavity occurs within 20 mm of the ground surface is explained below.

[0063] If a cavity occurs within the ground 20, the force that once supported the probe cone 1300 will disappear, and the probe cone 1300 will descend due to gravity. As the probe cone 1300 descends, the reflector 1440 is pulled by the connecting part 1500, and as the rotating shaft 1420 rotates, the reflector 1440 wrapped around it is released.

[0064] Therefore, in the initial state where the base surface 1441 is configured opposite the transparent cover 2100, one of the three reflective surfaces 1442, 1443, and 1444 is configured to face the transparent cover 1200, thereby reflecting the warning color. Specifically, since the length of the release of the reflector 1440 varies depending on the descent depth of the detector cone 1300, the warning color can be displayed in stages. In other words, the deeper the descent depth of the detector cone 1300, the longer the length of the release of the reflector 1440. Therefore, as the descent depth of the detector cone 1300 increases, the green reflective surface 1442, the yellow reflective surface 1443, and the red reflective surface 1444 are sequentially opposite the transparent cover 1200, and as a result, green, yellow, and red are reflected sequentially.

[0065] Next, refer to Figure 7 The ground subsidence detection device according to the third embodiment of the present invention will be described.

[0066] The ground subsidence detection device according to a third embodiment of the present invention mainly includes a main body 2100, a transparent cover 2200, a detection cone 2300, a display unit 2400, a connecting part 2500, and a flexible tube 2600. Here, the above configuration is similar to... Figure 6 The observed contents are basically the same, but there is a difference where the main body is bent at 90 degrees. Differences in form.

[0067] As the main body 2100 is formed in a curved form, the connecting part 2500 must also be formed in a curved form to connect the reflector 2440 and the detector cone 2300, and in order to support the curved part of the connecting part 2500, a support part 2120 is provided on the inner side of the main body 2100.

[0068] At this time, the transparent cover 2200 is attached to the upper end of the main body 2100 and can also be arranged in parallel with the direction of gravity, but preferably, it is arranged at a certain angle relative to the direction of gravity so that sunlight and the like can more easily enter the main body 2100.

[0069] According to this embodiment, the ground settlement detection device of the present invention can be installed not only vertically on paved surfaces such as roads that are laid horizontally on the ground, but also on paved surfaces such as retaining walls that are laid vertically. Furthermore, it can be installed across the columns of a building, the ground, or the foundation and ground of a building.

[0070] Next, refer to Figure 8 The ground subsidence detection device according to the fourth embodiment of the present invention will be described.

[0071] The ground subsidence detection device according to the fourth embodiment of the present invention mainly includes a main body 3100, an auxiliary main body 3150, a transparent cover 3200, a detection cone 3300, a display unit 3400, a connecting part 3500, and a flexible tube 3600. Here, the configuration of the main body 3100, the transparent cover 3200, the detection cone 3300, the display unit 3400, the connecting part 3500, and the flexible tube 3600 is similar to that of the main body 3100, the transparent cover 3200, the detection cone 3300, the display unit 3400, the connecting part 3500, and the flexible tube 3600. Figure 1 The contents observed are basically the same, but the difference is that the transparent cover 3200 and the display part 3400 are not directly combined with the interior of the main body 3100, but are combined through a separate auxiliary main body 3150.

[0072] Specifically, the auxiliary body 3150 is incorporated within the main body 3100, and like the transparent cover 3200 and the display unit 3400, it can be disposed at the upper end of the main body 3100. In this embodiment, the main body 3100 and the auxiliary body 3150 are joined by a threaded connection, but this is not a limitation, and they can be joined by various methods.

[0073] According to this embodiment, after the ground settlement detection device of the present invention detects the cavity, the auxiliary body 3150 can be easily separated from the main body 3100. Therefore, in the state of being installed on the paved surface 10 and the ground 20, the remaining tubular main body 3100 can serve as an inlet for an endoscope camera or an inlet for filling filler in the ground.

[0074] Finally, refer to Figure 9 The ground subsidence detection device according to the fifth embodiment of the present invention will be described.

[0075] The floor settlement detection device according to the fifth embodiment of the present invention mainly includes a main body 4100, a transparent cover 4200, a detection cone 4300, a display unit 4400, a connecting part 4500, and a flexible tube 4600. Here, the above configuration, except that the display unit 4400 also includes an auxiliary rotating shaft 4460 rotatably mounted within the main body 4100, is essentially the same as... Figure 6 The observed content is entirely the same.

[0076] Specifically, in this embodiment, the display unit 4400 includes: a rotating shaft 4420; an auxiliary rotating shaft 4460; and a reflector 4440, which is wound around the rotating shaft 4420 and has at least one reflective surface. The reflector 4440, after being wound around the rotating shaft 4420, is connected to the connecting part 4500 via the auxiliary rotating shaft 4460. In order to connect the connecting part 4500 to the center of the detection cone 4300, a support part 4120 for supporting the connecting part 4500 may also be provided inside the main body 4100.

[0077] Therefore, the reflector 4440, which is horizontally suspended between the rotation axis 4420 and the auxiliary rotation axis 4460, can be configured to be parallel to and opposite the transparent cover 4200, and to be in... Figure 6 In the embodiment, the reflective surface of the reflector 1440, which is wound around the rotating shaft 1420, is larger than the reflective surface of the transparent cover 1200.

[0078] According to the present invention, since the ground settlement detection device is fixedly installed after drilling holes in the paved ground, it can continuously detect ground settlement, that is, it can be detected at any time. Therefore, it can predict sinkholes, so that measures can be taken immediately to prevent sinkholes from occurring in advance.

[0079] In addition, without using an additional power source, the warning color is displayed by the detection cone that descends due to gravity or ground movement when a cavity occurs in the ground and by the reflection of a light source. The simple structure can improve durability and save costs.

[0080] In addition, not only professionals, but also ordinary people who move or settle in the area where the ground subsidence detection device is installed can easily determine whether there is ground subsidence through the warning color, thus eliminating anxiety about subsidence. By reporting, the detection personnel can play a role, thereby saving manpower.

[0081] This invention is not limited to the specific embodiments and descriptions described above. Any person with ordinary knowledge in the art to which this invention pertains may make various modifications without departing from the spirit of the invention as claimed in the claims, and such modifications are within the scope of protection of this invention.
