  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic diagram illustrating the overall configuration of the segment management system according to the present embodiment. FIG. 2 is a perspective view for explaining the configuration of the ring-shaped lining portion 2 of the shield tunnel 1 whose state is managed by the segment management system.

  As shown in FIG. 1, the ring-shaped lining portion 2 of the shield tunnel 1 is provided to protect a cylindrical excavation surface excavated by a shield machine 11 having a disk-shaped cutter on the front surface.

  As shown in FIG. 2, the ring-shaped cover portion 2 is formed in a cylindrical shape by continuing a plurality of annular rings 22 </ b> A, 22,... In the extending direction of the shield tunnel 1. And each ring 22A (22) is comprised by many arc-plate-like segment 21A-21F (21, ...).

  For example, the top ring 22A in FIG. 2 is formed in an annular shape by six arcuate plate-like segments 21A, 21B, 21C, 21D, 21E, and 21F. Here, the top of the shield tunnel 1 is the top end 1a, the bottom is the bottom end 1b, the right center point between the top end 1a and the bottom end 1b is the right end 1c, and the left center point between the top end 1a and the bottom end 1b. Is the left end 1d.

  The segment management system according to the present embodiment includes segments 21A-21F, 21,... Arranged as components of the ring-shaped lining portion 2. It is a system used when visually inspecting (inspecting) the state of (used)) from the inside of the shield tunnel 1.

  Here, the state of the segment 21 refers to a state that can be confirmed by the eye of the inspector M appearing on the surface of the segment 21 such as a crack (crack), water leakage, damage (cracked chip).

  As shown in FIG. 1, the segment management system is mainly configured by an input tablet 3 as a portable input terminal carried by an inspector M and a main body 4 installed in an office B or a management center on the ground. The

  That is, the inspector M enters the shield tunnel 1 from the shaft 12 with the input tablet 3 at the time of inspection, and inputs the state of the inspected segment 21 to the input tablet 3. The input data is transferred to a network communication device 46 such as a router in the shield tunnel 1 via wireless such as Wi-Fi, and transferred from the network communication device 46 to the main body 4 of the office B by wire.

  On the other hand, when there is no network communication device 46 near the input tablet 3, the input tablet 3 is brought back to the office B and the data stored in the input tablet 3 is transferred to the main unit 4.

  The main unit 4 includes a PC unit 41 configured by a personal computer, a storage unit 42 as a storage unit for storing data, a monitor 43 as an output unit, a keyboard 44 and a mouse 45 as input units. Mainly composed.

  The storage unit 42 may be a known storage medium such as a magnetic storage medium such as a hard disk, a flash memory such as a USB memory or an SD card, and an optical storage medium such as a CD-ROM.

  As the monitor 43, a known display device such as a liquid crystal display, an organic EL display, or a cathode ray tube display can be used. A printer can also be used as the output means.

  On the other hand, as shown in FIG. 3, the input tablet 3 is a small-sized computer having a screen such as a liquid crystal display or an organic EL display.

  The screen of the input tablet 3 is a touch panel, and the surface layer of the screen is an input operation unit. Then, after starting the application by pressing the start button 3a, the main screen 31 is displayed when the application is started.

  Although not shown, the input tablet 3 includes a storage unit such as a flash memory, and data stored therein can be transferred to the main unit 4 by pressing an upload button 312 on the main screen 31. .

  For example, when the input tablet 3 and the PC unit 41 are connected to each other by a wireless LAN such as Wi-Fi or wired, and the upload button 312 is pressed, the data stored in the input tablet 3 passes through the PC unit 41. It is stored in the storage unit 42.

  Conversely, the data stored on the main body 4 side can be transferred to the input tablet 3 by pressing the download button 313 on the main screen 31. This download button 313 can also be used when data, an update program, etc. are taken into the input tablet 3 via the Internet.

  When the selection icon 311 at the center of the main screen 31 is pressed, the ring selection screen 32 shown in FIG. 4 is displayed on the screen of the input tablet 3. A return button 3b is displayed on the screen other than the main screen 31, and the screen can be returned to the screen one level higher at any time.

  On the ring selection screen 32, the inspector M specifies the rings 22A, 22,. As described above, the ring-shaped lining portion 2 is configured by a plurality of rings 22 </ b> A, 22,... Continuing in the extending direction of the shield tunnel 1.

  Since the ring number is recorded in association with the excavation management data of the shield tunnel 1, the ring number for identifying the rings 22A, 22,. Therefore, the inspector M inputs the ring number of the ring 22A to which the state of the segment 21A-21F is to be input into the ring selection field 321.

  Since the segment type for each ring 22A, 22,... Is stored in advance in the input tablet 3, when a ring number is selected, the segment type of the ring 22A is automatically displayed.

  Further, the date and time when the state is input is also automatically taken from the internal clock of the input tablet 3 and displayed as the recording date. Moreover, when a crack etc. are repaired, the date which confirmed the repair can also be input.

  When the necessary items are input in this way and the execution button 322 is pressed, the segment selection screen 33 as shown in FIG. 5 is displayed on the screen of the input tablet 3. A selection icon 331 that is a simplified diagram of the ring and segment displayed on this screen corresponds to the arrangement of the segments 21A-21F of the actual ring 22A.

  Specifically, the arc-shaped piece buttons 331a, 331b, 331c, 331d, 331e, and 331f of the selection icon 331 correspond to the segments 21A, 21B, 21C, 21D, 21E, and 21F of the ring 22A, respectively.

  The annular ring 22A is a segment 21A when viewed in the direction of the face (front side of the shield tunnel 1 (shielding machine 11 side)) and when viewed in the direction of the wellhead (the rear surface of the shield tunnel 1 (vertical shaft 12 side)). The arrangement of −21F is reversed left and right.

  The direction in which the ring 22A viewed in which direction is displayed can be arbitrarily switched with a switching icon 332 having a switching function. FIG. 5 shows a display example in which the ring 22A is viewed in the face direction. In addition, the direction of the top end 1a, the lower end 1b, the right end 1c, and the left end 1d of the ring 22A is displayed so that the direction can be understood.

  Here, by pressing a ring information icon 333 on the segment selection screen 33, a ring information screen 34 as shown in FIG. 6 can be displayed. On the ring information screen 34, it is possible to input as information whether there is a state to be input to the ring 22A.

  For example, if there is a state to be input to any of the segments 21A-21F of the ring 22A, input the size of cracks and cracks, the presence or absence of rebar exposure, the presence or absence of cracks or water leakage, etc. by checking the check column 341. be able to.

  In the free field 343, the state can be written with arbitrary character string data. When the save button 342 is pressed, the information input on the ring information screen 34 is saved.

  On the other hand, when the segment 21A-21F whose state is desired to be input is determined, the piece buttons 331a-331f at the corresponding positions on the selection icon 331 on the segment selection screen 33 in FIG. 5 (in FIG. 5, the piece button 331c is selected 7 is displayed, the sketch screen 35 shown in FIG. 7 can be displayed.

  The sketch screen 35 is an input screen in which the orientation of the segment displayed in a plane is specified. That is, the inner peripheral surface of the segment 21C corresponding to the piece button 331c selected on the segment selection screen 33 is displayed on the sketch screen 35 as a square segment display unit 352 reflecting the aspect ratio of the actual segment 21C. .

  It can be confirmed by the display of the selected part 351a of the upper left position display part 351 of the sketch screen 35 whether the segment display part 352 is the segment 21C of the ring 22A.

  Further, the center arrow 351b of the position display unit 351 indicates the vertical direction of the segment display unit 352, and in the illustration of FIG. 7, the upper side of the segment display unit 352 is displayed with the lower end 1b side.

  This direction can be switched by pressing an icon indicated by an arrow 351b having a switching function. That is, when the direction is switched, the left side of the display of the segment display unit 352 becomes the face side and the right side becomes the wellhead side, and the display is the same direction as when the inspector M standing on the lower end 1b side faces the segment 21C.

  Information obtained visually by the inspector M can be drawn in the rectangular area of the segment display unit 352. For example, when drawing a cracked part or range, if the input icon 355A is selected and the corresponding part of the segment display unit 352 is traced with an input pen or a fingertip, the state of the broken part is drawn.

  Further, when drawing the location and range of water leakage, the state of water leakage is drawn by selecting the input icon 355B and tracing the corresponding location on the segment display unit 352.

  Furthermore, when drawing a crack location or range, the state of a crack is drawn by selecting the input icon 355C and tracing the corresponding location on the segment display unit 352.

  In addition, the pencil input icon 355D can be used to perform arbitrary drawing suitable for expressing the state on the segment display unit 352. The color of the pencil can be changed by the input icon 355E.

  Furthermore, by selecting the input icon 355F, line segments of various thicknesses can be drawn on the segment display unit 352. When rewriting or the like, the input icon 355G serving as an eraser can be selected to partially erase the drawn state. In drawing, the segment display unit 352 can be enlarged or reduced with the zoom icon 353.

  The state of the selected segment 21 </ b> C can be photographed by a camera (not shown) serving as an imaging unit provided in the input tablet 3. That is, when the shooting icon 354 at the upper right of the sketch screen 35 is pressed toward the place where the camera of the input tablet 3 is desired to be shot, a shot image is recorded in association with the segment 21C selected at that time.

  In this way, after the drawing and shooting of the state of the selected segment 21C is completed, the execution button 356 is pressed to store the input data in the storage unit of the input tablet 3 in association with the segment 21C.

  The segment state input by the input tablet 3 is performed by the inspector M in accordance with the progress of excavation or at an arbitrary timing. Then, the data recorded on the input tablet 3 is transferred to the main body unit 4 and stored in the storage unit 42 at an arbitrary timing.

  When the data of the plurality of segments 21,... Is accumulated in the storage unit 42 of the main body unit 4, the states of the plurality of segments 21,.

  FIG. 8 shows an example of the output screen 51 displayed on the monitor 43. In the output screen 51, a list display area 511 is generated on the left side, a segment development area 522 is generated in the middle, and an image output area 513 is generated on the right end.

  In the uppermost display setting field 511a, a range of rings to be displayed in the list display area 511 can be designated. For example, when “1” is entered at the start of the display setting field 511 a and “30” is entered at the end and the search button 511 b is pressed, a list of input data of ring numbers 1-30 is displayed in the list display area 511. The

  In the list display area 511, what kind of state data exists in each ring, a recording date, a repair date, an input comment, and the like are displayed as a data string so that it can be seen at a glance.

  When the ring number “5”, for example, in the list display area 511 is selected, the fifth ring is expanded and displayed in the segment expansion area 512. That is, the segments 21A-21F constituting the ring 22A are continuously displayed in a line.

  In the segment development area 512, positions of the top end 1a, the lower end 1b, the right end 1c, and the left end 1d in the circumferential direction of the shield tunnel 1 are displayed. Moreover, the indication of the wellhead side and the face side used as the direction of a longitudinal direction is also displayed.

  In the segment development area 512, a plurality of segments 21A-21F are continuously displayed with their positions and orientations matched. The storage unit 42 of the main body 4 stores data on the arrangement positions in the longitudinal direction of the respective rings 22A, 22,... Associated with the ring numbers and the segments 21A-21F,. Data such as the type, shape, orientation in the circumferential direction, and arrangement position are stored. Therefore, by reading those data, the segments 21A-21F, 21,... Can be continuously arranged in the correct direction and order.

  Furthermore, state data is displayed superimposed on the six segment diagrams displayed in succession. That is, on the sketch screen 35 of the input tablet 3, even if the segment is displayed in any orientation and the state is drawn, the state data is stored together with the orientation information. The status data can be displayed with an accurate orientation and position. For this reason, locations and ranges such as cracks, leaks, and cracks can be easily grasped including the position only by looking at the display of the segment development area 512.

  Further, when there is a photographed image associated with the segment, photograph marks 513a and 513a are displayed in the image output area 513 in accordance with the position of the segment, and the photographed image is output beside the photograph mark. For this reason, in addition to the sketched state, the state of the segment can also be confirmed by a photograph.

  The display result of the output screen 51 can be printed on paper by pressing the print button 514. This printing can also be performed separately for the list display area 511, the segment development area 512, and the image output area 513.

  FIG. 9 illustrates another output screen 52 displayed on the monitor 43. In the output screen 52, a list display area 511 is generated on the left side, and a segment development area 522 is generated on the right side.

  When a ring range is specified in the display setting field 521a in the uppermost row and the search button 521b is pressed, a data string of state data of the ring number in the searched range is displayed in the list display area 521. Further, a print button 524 for printing the display result of the output screen 52 on paper is displayed at the bottom.

  On the output screen 52, a plurality of rings 22A, 22,... Are displayed continuously in the segment development area 522. Then, in the displayed rings 22A, 22,..., The state data is output at the position of the segment 21A-2F where the state data exists.

  Next, the operation of the segment management system of this embodiment will be described.

  The segment management system of the present embodiment configured as described above includes an input tablet 3 for inputting the state of the segment 21 visually confirmed, and the input state data as a plurality of segments 21,. Is provided with a monitor 43 serving as an output means for outputting the image on the continuously displayed area.

  Furthermore, as shown in the segment selection screen 33 in FIG. 5 and the sketch screen 35 in FIG. 7, the input tablet 3 has a display in which the position of the input segment 21 can be specified by visual comparison.

  Furthermore, the segment display unit 352 displayed in a planar manner on the sketch screen 35 is displayed in a state where the direction is specified, and the displayed direction can be easily switched by tapping the arrow 351b having a switching function.

  Since the shield tunnel 1 is constructed in a cylindrical shape having a long extension distance, it is difficult to specify the position and orientation when the inspector M faces the segment 21 installed at a certain position. In addition, the segments 21,... That are continuously arranged in the circumferential direction and the front-rear direction have different directions that the inspector M can easily observe.

  Therefore, if the input tablet 3 has a switching function (332, 351b) for switching the direction of the segment displayed on the input screen (33, 35), the inspector M faces the segment 21 and then sees it. Since the display can be switched in the same direction, the inspector M can efficiently perform input operations such as drawing of the state without worrying about the direction.

  In this way, the state of the segment 21 as seen by the inspector M can be drawn as it is on the segment display portion 352 of the sketch screen 35, so that input is easy.

  On the other hand, the accumulated inspection results can be displayed on the output screens 51 and 52 of the monitor 43 in the same easy-to-understand state as the inner peripheral surface of the shield tunnel 1 in which the plurality of segments 21 are arranged.

  In addition, since the input tablet 3 can be drawn by selecting the type of state, it can be used for various extents such as cracks, water leaks, cracks, etc. It can be memorized accordingly.

  Furthermore, if the input tablet 3 has an imaging unit that can record a captured image in association with the identified segment 21, it can be managed together with the state data simply by capturing a point of interest at the time of inspection. Can do.

  That is, when shooting is performed with a camera different from the input tablet 3, the inspector M himself / herself must manage the captured image, and the ability of the inspector M to manage the state drawing and the photograph together. However, a system that can automatically manage state data and captured images together can stably perform management tasks.

  Further, if the captured image is output adjacent to the segment displayed on the monitor 43, the details of the state data displayed in the segment development area 512 can be immediately confirmed with the photograph in the adjacent image output area 513. can do. In other words, the drawn state data is easy-to-understand information for grasping the position and range of water leakage etc., but the thickness and the degree of deterioration of cracks can be grasped more accurately by looking at the picture. .

  Further, by printing the segment development area 512 and the image output area 513 at the same time, a report with photos can be easily created. Furthermore, if there is a report that can easily grasp the state and position of the segment, the management work of the segment 21 such as repair of defects such as water leakage treatment and cracks can be performed efficiently and accurately. it can.

  The embodiment of the present invention has been described in detail above with reference to the drawings. However, the specific configuration is not limited to this embodiment, and design changes that do not depart from the gist of the present invention are not limited to this embodiment. Included in the invention.

  For example, in the above embodiment, the case where the state data is input by the input tablet 3 and the state data is transferred to the main body unit 4 and output to the monitor 43 has been described. However, the present invention is not limited to this. For example, in addition to the function of inputting the state data, the portable input terminal can also have a function of an output means for displaying the plurality of segments 21...
