Description

Technology Field

[0001] The present invention relates to a device for determining ground subsidence, and more specifically, to a device for determining ground subsidence that can prevent major accidents caused by ground subsidence by visually checking the internal condition of the ground in real time. Background Technology

[0002] Generally, sinkholes—commonly known as cavities caused by ground subsidence or soil erosion in underground spaces—are one of the major factors in serious disasters that result in casualties and damages both globally and nationally. Consequently, Korea is mobilizing national resources to identify and prevent such accidents in advance.

[0003] For example, in order to prevent harm to the surrounding environment caused by underground excavation during all underground development projects, the Ministry of Land, Infrastructure and Transport requires the preparation of such harm prevention reports prior to the project and reviews and approves them. This instructs each approval agency to supervise the site and comply with the guidelines based on the underground safety assessment report—a harm prevention report submitted by the underground development project operator and reviewed and approved by the Ministry—and to thoroughly supervise the surrounding settlement, which is of the greatest concern among these.

[0004] However, conventional measurements to monitor the degree of settlement involve installing so-called settlement pins or surface settlement gauges at regular intervals around underground development sites. While this method relies on numerically displaying the settlement level to assess the surrounding area, it has limitations in accurately determining the actual movement beneath the ground. Furthermore, even if the settlement gauge readings indicate that no significant settlement has occurred, in the case of asphalt concrete, heavy loads are applied to the road, and due to the rigidity of the asphalt concrete, significant cavity formation is already taking place beneath the asphalt. However, this is often not detected until an accident caused by severe ground cavity has already occurred, resulting in the loss of the "golden time" needed to prevent major accidents.

FIG. 2 is a cross-sectional view of a key part showing a state in which a device for determining ground subsidence is installed on the ground according to one embodiment of the present invention. Specific details for implementing the invention

[0031] The configuration and operation according to a preferred embodiment of the present invention will be described in detail below with reference to the attached drawings.

[0032] This is intended to provide a detailed explanation sufficient for a person skilled in the art to easily implement the contents of the present invention, and does not imply that the technical concept and scope of the present invention are limited thereby.

[0033] In addition, it should be noted that when assigning reference numerals to the components of each drawing, identical components are denoted by the same numeral whenever possible, even if they are shown in different drawings; furthermore, terms specifically defined in consideration of the structure and operation of the present invention may vary according to the intent or convention of the user or operator, and the definition of such terms should be determined based on the content throughout this specification.

[0034] First, the configuration of a device for determining ground subsidence according to one embodiment of the present invention can be broadly divided into a housing installed in the ground where subsidence determination is required, a movable member installed at the lower interior of the housing and in contact with the ground, a motion recognition member that collects information regarding the movement of the movable member according to changes in the ground, a wireless communication module that transmits the information collected through the motion recognition member to a manager's terminal, and a power supply unit that supplies power to the motion recognition member and the wireless communication module. Each component is examined in more detail as follows.

[0035] First, the housing (100) is,

[0036] The top and bottom ends are open, and the interior is configured to have a certain length and the upper and lower ends are perforated with each other. A hole (610) is first formed at a predetermined depth in the ground (600) where subsidence is expected, and the housing (100) is installed by being fitted into the hole (610). At this time, the top of the housing (100) may be installed so as to be aligned with the surface of the ground (600) or to be sunken from the surface of the ground (600).

[0037] Here, the depth or diameter of the borehole (610) formed in the ground (600) can be varied depending on the conditions of the ground (600) and the analysis and design of a geotechnical engineer.

[0038] The housing (100) may be configured in a cylindrical shape, for example, and the shape may be configured in various shapes such as a polygon or an ellipse with an internal opening, without being limited to any one.

[0039] In addition, the material of the housing (100) can be composed of various materials, such as metal, as well as transparent, translucent, and opaque synthetic resins.

[0040] In addition, mounting brackets (not shown in the drawing) may be provided at regular intervals along the longitudinal direction inside the housing (100), and a wireless communication module (400), a power supply unit (500), or a motion recognition member (300) to be described later may be appropriately fixed to these mounting brackets.

[0041] Meanwhile, when the housing (100) is installed by being fitted into the hole (610) of the ground (600), the open top of the housing (100) is exposed to the outside, so rainwater or foreign substances may flow into the interior through the open top of the housing (100), so a cap (110) may be installed on the open top of the housing (100) to prevent this.

[0042] The cap (110) may be attached by press-fitting it to the open top of the housing (100), but it may also be configured to be detachable by forming a male screw on the upper outer surface of the housing (100) and a female screw on the inner surface of the cap (110) so that they can be screw-coupled to each other, in order to facilitate inspection, repair, and replacement of the motion recognition member (300), wireless communication module (400), or power supply unit (500) installed inside the housing (100).

[0043] The fluid member (200) is,

[0044] As it is installed in a state where it is in contact with the ground (600) below the perforation (610) within the aforementioned housing (100), movement occurs in conjunction with the movement of the ground (600), and through this movement, the condition of the ground (600) can be determined.

[0045] The movable member (200) can first be inserted into a hole (610) formed in the ground (600) for the housing (100) to be installed, and as the housing (100) is fitted into the hole (610) in this state, the movable member (200) inserted into the hole (610) is positioned at a certain height inside the bottom of the housing (100) that is subsequently fitted into the hole (610).

[0046] Of course, the housing (100) can also be installed by first positioning the movable member (200) inside the lower part of the housing (100) and then inserting the housing (100) into the perforation (610).

[0047] Accordingly, as the lower part of the movable member (200) comes into direct contact with the lower ground (600) of the drilling part (610), when movement occurs in the lower ground (600) of the drilling part (610), the movable member (200) moves together in response to this movement.

[0048] Here, a transparent partition (120) may be optionally installed inside the housing (100), and when the transparent partition (120) is installed, the movable member (200) is positioned below the transparent partition (120), thereby preventing interference between the movable member (200) and the motion recognition member (300) described later, which is positioned above the transparent partition (120), and at the same time, the surfaces of the motion recognition member (300) and the movable member (200) can maintain a constant distance.

[0049] These transparent partitions (120) can be formed in a flat shape, as well as a curved arc shape or a hemispherical shape with the central part sunken downward so that the movement of the fluid member (200) can be observed more effectively.

[0050] The movable member (200) comes into contact with the ground (600) and moves together in correspondence with the movement of the ground (600). In order to effectively identify this movement, it may be composed of sand consisting of multiple spheres or multiple granules. In the case of spheres, it may be composed of glass beads, plastic beads, or metal beads having a certain weight.

[0051] The fluid member (200) may be configured to have a specific color so that movement can be clearly identified, and in the case of a sphere, it may be configured as a sphere with a specific color, and in the case of sand, it may be configured by applying a specific color if necessary.

[0052] In another embodiment, the surface may be coated with a phosphorescent paint or a fluorescent paint so that the movement of the fluid member (200) can be effectively confirmed in a dark situation, and the fluid member (200) may be composed of a phosphorescent material or a fluorescent material.

[0053] The motion recognition component (300) is,

[0054] Information regarding the movement of a fluid member (200) located at the bottom of the housing (100) is collected while being installed inside the aforementioned housing (100).

[0055] The motion recognition member (300) may be, for example, a camera or a motion recognition sensor, and the camera may be a miniature camera considering the internal space of the housing (100). When such a camera is used, it is preferable to include a lighting device (310) to check the movement of the fluid member (200), and when the lighting device (310) is not used, an infrared camera may be used.

[0056] Here, when the motion recognition member (300) is configured as a camera, the video data related to the movement of the fluid member (200) is configured to be transmitted in real time to the manager's terminal via the wireless communication module (400) described later through the camera, so that the manager can check the status of the fluid member (200) in real time through a terminal such as a PC, laptop, mobile phone, or CCTV.

[0057] And when the motion recognition member (300) is configured as a motion recognition sensor, an infrared sensor, an ultrasonic sensor, an image sensor, a radar sensor, or a motion sensor may be applied as the motion recognition sensor, and when the movement of the fluid member (200) is converted into change amount data such as a numerical value by such a motion recognition sensor and transmitted in real time to the manager's terminal through a wireless communication module (400), the manager can check the status of the fluid member (200) in real time through a terminal such as a PC, laptop, mobile phone, or CCTV.

[0058] In addition, as the motion recognition member (300) is configured with a motion recognition sensor and a camera, the manager can more accurately check the condition of the ground (600) through data on the amount of change and video data according to the movement of the fluid member (200).

[0059] The wireless communication module (400) is,

[0060] It is a means for transmitting relevant information to a manager's terminal by connecting to a motion recognition member (300) that has collected information about the movement of the aforementioned fluid member (200).

[0061] These wireless communication modules (400) may be composed of, for example, a Wi-Fi module, a Bluetooth module, a Zigbee module, a LoRa module, a Cellular module such as GSM, LTE, 5G, an NFC (Near Field Communication) module, or an RFID (Radio-Frequency Identification) module.

[0062] Here, it is preferable that the administrator's terminal also be configured to have a separate wireless communication module embedded so that it can receive information transmitted through this wireless communication module (400), and in the case of a mobile phone, an application that can receive and analyze such information and provide various forms of information to the administrator may also be installed.

[0063] The power supply unit (500) is,

[0064] It serves to supply power necessary for the aforementioned motion recognition member (300) and wireless communication module (400), and may be configured as a wireless battery and installed inside the housing (100), and when necessary, a power line connected to an external power source may be introduced into the housing (100) and connected to the motion recognition member (300) or wireless communication module (400).

[0065] In another embodiment of the power supply unit (500), a solar cell module may be installed on the upper surface of the cap (110) without using a wireless battery, and the power required for the motion recognition member (300) and wireless communication module (400) may be supplied using energy obtained through the solar cell module. Alternatively, the power supply unit (500) may be configured to supply power required for the motion recognition member (300) and wireless communication module (400) using energy obtained through geothermal energy inside the ground (600). If necessary, the power supply unit (500) may be configured to be composed of a wireless battery and a solar cell module together to minimize the power consumption of the wireless battery.
