Further, the prior art document 1 described, “A wireless communication antenna is appropriately disposed at a tunnel construction site, and an image display function, an image photographing function, a voice call function, and a data communication function are provided that can communicate via the wireless communication antenna. Deploying a wireless communication device for workers and forming a network composed of the wireless communication device for workers, a surveying device placed at the tunnel construction site, and a computer system for managing tunnel construction outside the tunnel A comprehensive management system is proposed.
However, the present invention focuses on construction management at the tunnel construction site office, and does not consider the burden and accuracy required for the face observation report creation of the face observation worker.
JP 2005-344418 A

  Therefore, the main problem of the present invention is to reduce the burden required for preparing the face observation report by the face observation worker and to improve the accuracy thereof. Other issues will become apparent from the description below.

The present invention for solving the above problems is as follows.
<Invention of Claim 1>
The tunnel construction site office equipped with the management server is connected to the face area in the tunnel excavation mine via a LAN, the LAN is extended along with the tunnel excavation and movement of the face area, and the access points of the LAN are sequentially added. ,
The face observation worker observes the face before the face, inputs the captured face photograph and information necessary for making the face observation report to the portable operation terminal, and wirelessly transmits the data to the corresponding access point. Sent to the management server via the LAN,
A management method in a tunnel construction area, characterized in that a final face observation report is created based on the transmitted information.

(Function and effect)
Face observation is an important task in tunnel excavation. In other words, by observation of the face, the station number (station number), the distance from the wellhead, the section number, the support pattern, the height of the earth covering, the rock name / geological age, the rock group, the rock name code, the specifications of the auxiliary method, Observe the details of additional support work, A, B measurement, presence / absence of collapse, presence / absence of invert early closure, compressive strength, weathering alteration, crack observation, crack condition, strike slope, amount of spring water, deterioration, etc. In the face observation data sheet, for those subject to the five-step evaluation category, enter the evaluation category for the left shoulder, center and right shoulder of the face, and enter the evaluation score on the face observation data sheet. Is. In addition, a photograph of the actual face is attached to the face observation data sheet, and a sketch with rocks and cracks is created corresponding to the photograph of the face, and various observation evaluations (for example, , “There are rocks that have slid down with large meshes”, “Andesitic pyroclastic rocks” and “Fractures are fine and the interval is 5 to 20 cm”). These examples are described in detail on pages 247 to 270 of the “Tunnel Standard Specification (Mountain Construction Method) / Description” established in 2006.

  However, in the past, most of the face observation element groups were written in a simple memo on the field book (handbook), returned to the tunnel construction site office, and then the memo data on the unfilled face observation data sheet. And based on the memory, the final data was copied to a blank face observation data sheet. In addition, after returning to the tunnel construction site office, the shooting data for face observation is printed out as a photograph, affixed to the face observation data sheet, a sketch is created corresponding to the photograph, and it is written in the sketch. Items to be recorded were written in the face observation data sheet based on notes and memories from the field book.

However, there are many items (elements) to be entered in the face observation data sheet, and even if all of these are written down in the field notebook, they are not filled in after returning to the tunnel construction site office. When copying to the face observation data sheet, there are many memory elements, so that an entry error is likely to occur.
Furthermore, since the items to be entered in the sketch corresponding to the face observation photograph are entered based on the notes and memories from the field book, the accuracy is not sufficient.

  However, according to the present invention, the face observation worker observes the face directly in front of the face and observes the face face and information necessary for making the face observation report on the portable operation terminal. Since it is input directly, it is possible to eliminate the cause of errors such as a difference in memory and to improve accuracy.

  In addition, regarding the items that have been entered in the sketch corresponding to the conventional face observation photograph, in the present invention, for example, image data is directly taken into a portable operation terminal equipped with a camera function, or brought separately. Capture the image data taken by the camera into the operation terminal, and fill in the items to be recorded by tracing the image on the image data display screen or the image data display screen (for example, as described above) Enter the rocks and cracks), and the observation judgment information (for example, “There are rocks that have slid down with large meshes”, “Andesitic pyroclastic rocks”, “The cracks are fine, and the interval is 5 to 20 cm”). For example, sketch-like entries and observation evaluation items will be accurate.

  Conventionally, the entries in the face observation data sheet have become the standard for changing the support pattern (addition, enhancement, reduction of support work), and if such change is necessary, the contractor must notify the owner's technical supervisor of the current face. We ask for observation, and under the consent of the owner, the next zone is constructed while adopting the changed support pattern. In this way, the contractor presents the face observation data sheet to the owner's technical supervisor whenever he / she decides that the support pattern needs to be changed based on the contents described in the face observation data sheet. I go to the mountains from the city to observe the face.

  However, every time the support pattern is changed, the fact that the technical supervisor goes to the working face is a factor in the decrease in construction efficiency. However, in reality, since it is not possible to go to the face, it is difficult to obtain information that can be sufficiently confirmed only by the contents of the face observation data sheet. According to the present invention, the reliability of the information necessary for determining the change of the support pattern becomes high. For example, it is possible to reduce the number of times that the technical supervisor is seconded or to eliminate the second.

<Invention of Claim 2>
The management in the tunnel construction area according to claim 1, wherein the manager of the field office gives instructions to the face observation worker via the LAN based on the face situation reflected in the received face picture. Method.

(Function and effect)
The face observation worker may be a beginner in addition to having sufficient experience. In this case, by giving instructions to the face observation worker via the LAN based on the face situation reflected in the face photograph transmitted to the management server via the LAN, information necessary for preparing the face observation report is obtained. It becomes possible to input accurately. Moreover, even if the face observation worker is an experienced person, it is possible to gain higher or more accurate information entry experience.

<Invention of Claim 3>
The face observation worker inputs the face observation judgment information to the captured face photograph, inputs the operation terminal to the management server, and transmits it to the management server. Management method.

(Function and effect)
When the above-mentioned “face observation judgment information” is added to the captured face photograph, it can be used without entering the relationship between the face photograph and the judgment information by inputting to the operation terminal and sending it to the management server. It is.

<Invention of Claim 4>
Furthermore, the management method in the tunnel construction area | region of any one of Claims 1-3 which transmits the dust amount data of the dust amount detector provided in the mine to the management server via the LAN.

(Function and effect)
In tunnel excavation, the amount of dust is important for the health management of workers. However, according to the present invention, if the dust amount data of the dust amount detector provided in the pit is transmitted to the management server via the LAN, real-time management associated with the progress of the tunnel excavation work and the face is performed. It can be carried out.

  As described above, according to the present invention, it is possible to reduce the burden required for preparing the face observation report by the face observation worker and to improve the accuracy thereof.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.
FIG. 1 shows the equipment relations installed around the tunnel 1 excavation site, and shows a state in which the excavation from the wellhead 2 has progressed to some extent. 3 is a face. Outside the wellhead 2, a road and a field office 4 are built. In addition, a spray material plant 5, a power distribution facility 6, a muddy water treatment facility 7, and the like are installed.

  In the tunnel 1 tunnel, various excavation equipment, such as rock drills, sprayers, trucks, dust collectors, surveying equipment, carbon dioxide concentration meters, and dust amount detection for controlling and managing dust amounts in connection with the dust collectors. Various detectors 8 such as a detector 8A are provided.

  Then, the face observation worker 10 brings a portable operation terminal 11, a mobile phone 12, and the like, and their output information is wirelessly sent to the repeater 20a and installed in the field office 4 via the wired LAN 20. Can be transmitted to the management server 21.

  Furthermore, since the tunnel is dug sequentially and the face 3 advances, the LAN 20 is extended sequentially through the repeaters 20a, 20a... To ensure the stability of the transmitted / received radio waves.

  The field office 4 is provided with a signal processing device 22 including a CRT display device, and information can be processed with the management server 21.

  Under the above configuration, the amount of material used in the spray material plant 5 outside the wellhead 2, the power received and distributed in the power receiving and distribution facility 6, the accumulated power used in time units, the amount of muddy water in the muddy water treatment facility 7 and its concentration Are exchanged with the management server 21 as control signals and recording signals.

  On the other hand, from the tunnel 1 mine, signals from the various detectors installed in the mine are transmitted to the management server 21 via the LAN 20 or wired separately from the LAN 20, and the signals from the various detectors are It is used for safety management in one tunnel. In particular, the signal of the dust amount detector 8A related to the mine dust collector is taken into the indicator and the alarm device 9 installed at the entrance of the pit 2 as necessary, and is used to determine whether or not the mine can enter the tunnel 1. It is.

  On the other hand, the face observation worker 10 brings a portable operation terminal 11, a mobile phone 12 or the like into the tunnel 1 tunnel, goes out to the face, images the face 3 with a CCD camera (not shown), etc., and visually observes it. As described above, information necessary for creating the feather observation report is directly input to the portable operation terminal. In this case, it is desirable to enter a sketch and its comment on the face imaging signal. When these operations are completed, the data is transmitted to the management server 21 via the LAN 20 via the relay machine 20a as the nearest access point.

  Other workers or face observation workers 10 send survey information such as displacement in the tunnel 1 mine, support construction information, operation information of various excavation equipment, etc. to the management server 21 via the LAN 20 as necessary. Or the site office 4 can be notified using a telephone function. Then, if necessary, it is possible to receive a telephone call from the site office 4 side or to retrieve current or past information from the management server 21.

  Explaining how to extract information from the management server 21. When processing a survey signal of a face or a support work, if a computer is brought into the tunnel 1 tunnel, a simple calculation can be performed by the computer. It is difficult to process. Therefore, the survey signal at the face is once transmitted to the management server 21 via the LAN 20 and is subjected to complicated calculation processing such as relating to other accumulated information, and the result is transmitted via the LAN 20. If the operation terminal 11 receives the coordinates, the coordinate value of the face or support work can be calculated in real time, so that the work accuracy of the face or support work can be improved.

  On the other hand, the face observation worker 10 receives the past face data from the management server 21 via the LAN 20 and becomes important reference information for determining the current state of the face. It is possible to more appropriately determine the pattern change.
