Description

Tunnel excavation method and observation system for establishing a communication line for real-time closet observation and monitoring {TUNNEL EXCAVATING METHOD HAVING BUILDING STEP COMMUNICATION LINES FOR REAL TIME OBSERVATING AND MONITORING A TUNNEL WORKING FACE}

The present invention relates to a construction method and a system capable of monitoring the tunnel excavation situation and the state of the excavation tunnel in real time by observing in real time the information collected on the excavation tunnel's membrane scene as well as the field observer and the remote center supervisor. More specifically, after the blasting for tunnel excavation, the communication line is extended to a non-communication area, and a vehicle-based multi-sensor measuring system (MMS) is entered into the excavation tunnel's end face to close the end of the excavation tunnel. It relates to a tunnel excavation method and an observation system of a communication line construction method for real-time close observation and monitoring that collects information on cotton and enables real-time communication and monitoring.

Tunnel excavation is indispensable in the construction of roads and railways through mountainous terrain. Tunnel excavations are usually perforated and charged, blasted and ventilated. It is conducted in the order of processes according to NATM (New Austrian Tunneling Method) techniques such as burr and pumice treatment, shockcrete pouring, support hole and rock bolt installation, and concrete lining.

However, since the blasting process and other excavation work performed in the tunnel excavation process are performed before the ground construction for enhancing the stability of the excavation tunnel, the risk of various accidents such as the collapse of the tunnel during the excavation process such as blasting was very high. Therefore, for the safety of site observers and other efficient blasting processes, the rock quality, carcinoma, and joint distribution of the membrane surface were identified, and the rocky condition of unexcavated sections was also predicted. In order to make such a judgment and prediction, an observer collects various data such as a film scene generated after a blasting process or collects various data, such as bending, directly at the site, makes a judgment, or asks the supervisor at a remote site after the observer collects only the data. The cancer judgment was made by passing.

However, in the past, data collection and data processing are performed only on the sole discretion of field observers, so the collected data and the results of the dark judgment were subjective and unreliable. In addition, even if the judgment was made separately through specialized supervisors, the time required for data collection and judgment was increased because field observers had to deliver the collected data to the remotely located centers at different times. Since it should have been judged only by relying on the collected data, the supervisor's judgment result also had limitations in achieving complete objectivity.

In order to solve this problem, it has been conventionally proposed to provide communication equipment at the entrance of the excavation tunnel, and after the blasting process, a field observer moves to the entrance of the excavation tunnel and transmits data collected at the excavation point to the center. However, in the conventional method, as the depth of the excavation tunnel becomes deeper, the moving distance of the field observer for transmitting the collected data becomes longer, thereby delaying the supervisor's monitoring time for supplementing and further collecting the collected data, and thus excavating the excavation tunnel. The increase in the time required to judge cancer could not be completely eliminated. In addition, since the supervisor cannot supervise the field observer or collect the desired data directly when collecting the scene-related data, there was still the problem of relying only on the data collected by the field observer.

Moreover, if decision-making is needed during field work, such as close observation, or urgent cancer determination is required, the field observer should stop the collection work, visit the remote center directly, interview the supervisor, and conduct discussions, etc. Judgment work time occupied a small proportion during the excavation period.

S10; Excavation steps

Tunnel excavation may be constructed by a blasting method and a drill machine method, and the excavation method of the tunnel excavation method according to the present invention is not limited to a specific method. In the tunnel excavation method of this embodiment, since the field observer M and the supervisor should be able to observe the film surface 21 as shown in FIG. 4(a), the film surface 21 can be easily observed immediately after excavation. In order to ensure that the excavation equipment was withdrawn, a blasting method was applied. For reference, as shown in FIG. 4(b), the excavation worker installs and charges the charge 22 at multiple designated positions of the curtain surface 21, thereby excavating the curtain surface 21 to a design depth.

When the charge section 22 is generated through the explosion of the charge charge 22, the vehicle 110 of the MMS 100 is closed by transporting and removing the burr 23 generated in the blasting process from the excavation tunnel as shown in FIG. 5(a). Make it possible to enter the section without jamming.

S20; Reinforcement steps

Upon completion of excavation according to the design, the internal structures 22a and 22b of the excavation tunnel are extended to a length corresponding to the excavation depth of the tunnel.

The internal structures 22a and 22b are minimal foundation processes for preventing tunnel collapse immediately after blasting, and the foundation processes may include rock bolt installation, shockcrete installation, and steel beam installation. have. For reference, the ground of an excavation tunnel may be unstable immediately after excavation by blasting. However, after the excavation, it is very important to reduce the risk of collapse accidents because the vehicle 110 and the field observer M of the MMS 100 enter the tunnel after excavation for observation and measurement of the membrane surface 21 of the excavation tunnel. To this end, after the tunnel excavation, the internal structures 22a, 22b for reinforcing the ground are installed to be extended as shown in FIG. 5(b) by the excavation depth, so that the field observer M can safely observe and survey the ground. .

Also, the internal structures 22a and 22b may be members for installing the communication repeater 12, and for this purpose, the communication repeater 12 and other wiring trays for wiring construction are exemplified as the internal structures 22a and 22b. Can be. The tunnel excavation method of the present invention allows the real-time observation of the excavation tunnel's membrane and observation and survey data immediately after excavation, as well as the field observer (M), as well as the remote supervisor in real time, thus extending the depth of the excavation tunnel in the excavation process. In response, the communication line must be extended. Therefore, immediately after excavation, the inner structures 22a, 22b for installation of the communication lines are installed on the inner wall of the tunnel as shown in Fig. 5(b). The communication lines constituting the communication line, the communication repeater 12 and other frequency amplifiers (not shown) are selectively installed in the extended internal structures 22a and 22b.

S30; Communication line extension step

In order to enable wireless communication in the closing section, a communication line between the communication repeater 12 and the setup box 11 is further extended along the internal structure 22.

The communication line is a communication means that enables the control mobile 200 and the MMS 100 of the field observer M located in the excavation tunnel to access and communicate with the remote server 300 online. In this embodiment, a setup box 11 for Internet access is installed at the entrance of the excavation tunnel, and a communication repeater 12 is installed in the excavation tunnel to form a communication line. At this time, communication between the setup box 11 and the communication repeater 12 may be performed in a wired or wireless or wired or wireless manner.

In the case of the wired method, a communication repeater 12 is installed at a location where wireless communication is possible in the closet section, and a communication repeater (such as an optical communication cable or a general electric wire cable) drawn out from the setup box 11 is routed along an excavation tunnel. 12). Therefore, after the excavation, the communication repeater 12 is transferred to the wireless communication range in the closet section, and the communication line extends by the previous distance of the communication repeater 12.

In addition, in the case of the wireless method, a plurality of communication repeaters 12 are installed along the excavation tunnel at intervals in which communication is effective, and after the additional excavation of the tunnel, the communication repeaters 12 within the range of wireless communication possible in the newly created close section. 12') by adding the communication line. Therefore, the outgoing signals of the MMS 100 and the control mobile 200 are transmitted to the neighboring communication repeater 12 through the additionally installed communication repeater 12', and the neighboring communication repeater 12 is sent to other neighboring communication repeaters. The outgoing signal is transmitted to the setup box 11 by sequential serial communication in which the signal is transmitted. In the case of the wireless method, a frequency amplifier for amplifying the radio frequency of the signal may be further reinforced.

In addition, in the case of the wired or wireless method, the communication repeaters 12 and 12' of some sections are connected by a separate communication line depending on the state of the tunnel section and other site conditions, and the communication repeaters 12 and 12' of other sections are connected. Connects communication by wireless communication.

As described above, when the depth of the tunnel is increased through excavation, the communication line is additionally wired or a communication repeater (12, 12') is added to a location where wireless communication is possible in the closest section as shown in FIG. 5(b). By additionally installing, the communication line with the setup box 11 is extended, and the MMS 100 and the control mobile 200 in the closest section connect to the external Internet communication network via the extended communication line, and the remote server 300 ) To establish a communication environment.

For reference, if wireless communication is possible even with an existing communication line in the closet section created after excavation, the communication line extension process may be omitted (S25).

S40; MMS setup phase

If the communication line is extended after additional excavation as shown in FIG. 5(c) and FIG. 6, the vehicle 110 of the MMS 100 enters the closest section, and the field observer M controls the MMS 100 The communication repeaters 12 and 12' of the communication line are connected to the remote server 300 through the medium.

The MMS 100 transmits an identification code such as an IP or device ID to the remote server 300 itself, and the data processing module 320 of the remote server 300 recognizes the received identification code and transmits the MMS 100. Identify and authorize login. The login attempt of the MMS 100 may be made manually through the operation of the MMS 100 of the field observer M, or the MMS 100 actively sends an identification code to the remote server 300 according to the setting process. It might be.

On the other hand, the control mobile 200 of the field observer M accesses the remote server 300 through a communication line and inputs the ID of the field observer M or the unique code of the control mobile 200, and the remote server 300 ) Recognizes the received identification code to identify the control mobile 200 and authorizes login.

The MMS 100 logged in to the remote server 300 and the field observer M complete all preparations for observation and surveying of the barrier 21 while performing data communication.

For reference, the control mobile 200 and the MMS 100 of this embodiment communicate with each other through the relay of the remote server 300, and for this, the remote server 300 communicates with the MMS 100 and the control mobile 200. Each login procedure for data communication is performed. However, the control mobile 200 may perform data communication with the remote server 300 through the MMS 100 as a relay, and thus the remote server 300 may only perform a login procedure of the MMS 100.

S50; Stage measurement stage

The MMS 100 transmits the collected survey data to the remote server 300 by surveying the membrane scene 21 of the excavation tunnel, and the control mobile 200 receives the survey data.

The generated survey data is transmitted by the MMS 100 to the remote server 300 through a communication line, and the data processing module 320 of the remote server 300 processes the survey data to be monitored and supervised by the supervisor. In order to be able to output through the monitoring module 330 as shown in Figure 7 (b). In addition, the remote server 300 transmits the received survey data to the control mobile 200 in the field. The installation program of the control mobile 200 processes the received survey data and outputs it to the screen as shown in FIG. 7(a), and the field observer M sees the survey data output to the control mobile 200 and closes it. By analyzing the state of (21), it is possible to directly input additional contents, such as recording by hand or sketching based on the output film image, into the control mobile 200. To this end, the control mobile 200 generates information input by the remote observer M as input data in response to the survey data and transmits it to the remote server 300, and the remote server 300 receives and sets the input data Process according to the process. Here, the setting process is an execution algorithm of a program that calculates information (input data) input by a field observer (M) for analysis of a scene, and may be set in various forms by an operator according to the observation method of the scene (21).
