Description

Tunnel construction site informatization integrated management system and excavation construction method

The present invention relates to an informatization integrated management system and excavation construction method of a tunnel construction site. More specifically, by grasping and integrated management of the situation of a tunnel construction site in real time, a remote supervisor can also grasp and manage the work environment at once. It is also about an integrated system and excavation construction method that can check and collaborate with field observers in real time with field observers.

Tunnel excavation is essential in the construction of roads or railways passing through mountainous terrain. Tunnel excavation usually involves drilling and loading, blasting and ventilation. The process follows the NATM (New Austrian Tunneling Method) technique such as burr force and pumice stone treatment, shockcrete pouring, support and rock bolt installation, and concrete lining.

Such tunnel excavation construction is a large-scale project requiring a large number of professional manpower to perform the above process, a long construction period, and a large consumption budget. Moreover, tunnel excavation involves excavating rock formations such as mountainous terrain and performing blasting work for excavation. Therefore, the work environment is very dangerous construction. Therefore, a method and various systems for checking and managing the safety of workers and the stability of the excavation tunnel have been desperately required.

Meanwhile, for safer and more effective blasting work, it was necessary to accurately identify the rock to be excavated, design a blasting design to prevent collapse, and prepare various reinforcement works. In general, rock quality, rock type, and joint distribution, etc., are determined to determine the state, and the state of the makjang surface to be created by excavation can be predicted based on the makjang surface created by the previous excavation. Therefore, for a more accurate, objective and reliable cancer diagnosis, it is only possible to accurately collect various information about the scene from the field and make a decision by a large number of professional personnel.

For cancer determination and prediction, conventionally, the observer collects various data such as bending or filming the scene that occurred after the blasting process at the site and makes the cancer determination, or after the observer collects only the data, it is transmitted to the supervisor at a remote location. Thus, the judgment was made.

However, in the prior art, data collection and data processing depend only on the independent judgment of field observers, so the collected data and cancer diagnosis results are subjective and not highly reliable. In addition, even if the cancer diagnosis is performed separately by professional supervisors, the time required for data collection and cancer determination has increased because the on-site observer has to deliver the collected data to the remote center with a time difference. Since cancer diagnosis should have been made only by relying on the collected data, the supervisor's cancer diagnosis result also had limitations in having complete objectivity.

In order to solve this problem, conventionally, a method of equipping the entrance of the excavation tunnel with communication equipment, and after the blasting process, a field observer moves to the entrance of the excavation tunnel and transmits the data collected at the excavation point to the center has been proposed. However, in this conventional method, as the depth of the excavation tunnel becomes deeper, the moving distance of the field observer for delivery of the collected data becomes longer, and this delays the monitoring time of the supervisor for supplementation and additional collection of the collected data. The increase in the time required for cancer diagnosis could not be completely eliminated. In addition, when the supervisor collects the data related to the scene, there is still the problem that cancer diagnosis must be made based on the data collected by the on-site observer, since it is not possible to supervise the on-site observer or directly identify and collect the desired data.

Moreover, if a decision-making is required or an urgent cancer diagnosis is required during field work such as blind observation, the on-site observer should stop the collection work, visit the remote center directly, meet with the supervisor, and discuss the cancer. Judgment time took up a significant portion of the excavation work period.

The integrated management system of this embodiment includes a communication line, an MMS 100 , a control mobile 200 , an identification terminal 18 , scanners 14 and 15 , and a remote server 300 . Furthermore, the integrated management system of this embodiment may further include a CCTV 16 , a sensor box 17 , and a measuring instrument 19 .

The communication line is extended to enable wireless communication in the last section of the excavation tunnel according to the tunnel length that is deepened according to the excavation, and the communication repeaters 12, 12'; possible to be connected. The setup box 11 is an interface for Internet access, and is installed at the entrance of the excavation tunnel. On the other hand, the communication repeater 12 is installed in the excavation tunnel to form a communication line. In this case, communication between the setup box 11 and the communication repeater 12 may be performed in a wired or wireless manner or in a wired or wireless manner.

The communication line is extended step by step whenever an excavation operation is performed step by step, so that an excavation official (AM) such as an excavation worker or a field observer enables wireless communication even in the last section.

The MMS 100 collects and transmits the survey data by surveying the final surface of the excavation tunnel, and the operation is controlled according to the operation signal received through the communication line. In the MMS 100, various types of surveying devices 120 and other additional equipment are mounted on the vehicle 110 and transported to the last section of the excavation tunnel, and under the control of a field observer or remote server 300, the end face of the excavation tunnel measure the For the MMS 100 for measuring the scene, various types of surveying devices 120 for 3D surface analysis of the scene may be mounted. Typically, Lidar (Laser Radar, Light Detection And Ranging) or one or more A PTZ camera (Pan-Tilt-Zoom Camera) may be exemplified. Here, the PTZ camera makes it possible to three-dimensionalize a single point of the scene by shooting one or two or more points at various angles and aiming angles at different positions, and then using a combination of screens. For reference, when the PTZ camera is implemented as the surveying device 120, a focus laser (not shown) may be further configured so that the PTZ camera can accurately aim and shoot at a designated location on the final scene. The focus laser forms a target for determining a shooting distance and an appropriate location on the final scene, so that the PTZ camera can take a picture using the target as a reference point, and synthesize a shot image based on the target to make it three-dimensional.

In addition, since the MMS 100 operates in a dark section called an excavation tunnel, a lighting device 130 for optical imaging may be added, and when the survey device 120 is a lidar, the video image of the last scene and the last section A photographing device 140 such as a general digital camera or a moving picture camera may be additionally installed to collect the images.

In addition, the MMS 100 further includes a transceiver 150 that transmits the survey data collected and generated by the surveying device 120 and the photographing device 140 and receives an operation signal from the outside. In addition, the MMS 100 further includes a controller 160 . The controller 160 processes the information collected by the surveying device 120 and the photographing device 140 to generate survey data, and controls the mobile 200 and the remote server 300 through the transceiver 150 . It transmits to one or more selected ones, and controls the operation of the surveying device 120 and the photographing device 140 according to the operation signal.

The control mobile 200 receives and outputs the survey data of the MMS 100 via a communication line, and transmits a control signal for controlling the MMS 100 . To explain this in more detail, the control mobile 200 controls the operation of the MMS 100 by the on-site observer and receives the survey data surveyed by the MMS 100 online, such as a photographed image of the scene and survey information, etc. As a means for observing , a template, smartphone, notebook, etc. that are easy to carry by field observers, enable wireless communication, and can visually check photographed images and survey information through a screen may be exemplified.

The identification terminal 18 transmits a unique code so that the location of the person involved in the excavation (AM) can be identified in the excavation tunnel, and a safety means for guiding the person involved in the excavation (AM) in the danger situation from the remote server 300 of the dangerous situation am. In general, it is good that the excavation personnel (AM) is always configured to carry accessories, preferably installed in a hard hat or seat belt. The configuration and function of the identification terminal 18 will be described in more detail below.

The scanner 14, 15 recognizes the unique code, generates and transmits the location information of the identification terminal 18, and communicates with the communication line in the last section of the excavation tunnel according to the tunnel length that is deepened according to the excavation and recognizes the unique code Added to make this possible.

The scanners 14 and 15 recognize the unique code transmitted from the identification terminal 18 while scanning the inside of the tunnel at all times or periodically and grasp the corresponding location information. For reference, since the identification and location of the person involved in the excavation (AM) must be confirmed even in the last section where the tunnel is created through excavation, the scanners 14 and 15 are additionally installed like communication lines whenever the tunnel is additionally excavated.

On the other hand, the scanners 14 and 15 have different functions depending on the installation location. Since the scanner 14 installed at the tunnel entrance allows to check the tunnel entry and exit of the excavation personnel (AM), even at a remote center as shown in (a) and (c) of FIG. It is possible to check whether or not there is a shift, whether the field observer enters or leaves, and the like. A plurality of scanners 15 installed inside the tunnel grasp the positions of the excavation officials (AM) scattered throughout the excavation tunnel (see FIG. It is possible to check whether the position is deviated and whether a work vehicle such as a bulldozer is in proximity. In addition, it is possible to quickly respond to the emergency by quickly identifying the person in charge of excavation (AM) and the location where the emergency has occurred and notifying the person in charge and the supervisor of the center as shown in the drawing of FIG.

The remote server 300, the observation DB 310 for storing and managing the survey data received from the MMS 100, the related DB 350 for storing and managing the identification information of the excavation related person (AM), and storing the work information Management DB 340, and transmits the survey data to the control mobile 200, generates an operation signal according to the control signal received from the control mobile 200, and transmits it to the MMS 100, via a communication line A data processing module 320 for generating a processing signal by comparing the received position information and a unique code with the work information and corresponding to a prescribed position, a monitoring module 330 for displaying the survey data, and the corresponding processing signal according to the processing signal and a remote server 300 configured with a guide module 370 for transmitting guide information to the identification terminal 18 of a unique code.

The remote server 300 searches and observes the status information of the makjang section and the makjangmyeon received from the MMS (100) in real time with the on-site observer, and the operation of the MMS (100) is performed by a supervisor located remotely in addition to the makjang section. As a means for controlling, it processes, stores and manages the survey data received from the MMS 100, generates and transmits an operation signal for controlling the operation of the MMS 100, and communicates online with the control mobile 200 and Conduct communication between field observers and supervisors.

When each component of the remote server 300 is described in more detail, the observation DB 310 includes not only the survey data received from the MMS 100, but also additional data generated by field observers and supervisors based on the survey data. It is used as the base data that allows experts, etc. to finally predict the rock quality, carcinoma, and joint distribution, etc. of the rock by storing and managing it.

The related DB 350 manages and stores identification information related to the excavation related person (AM) by unique code. Therefore, when the unique code is received from the scanners 14 and 15, the corresponding identification information is retrieved from the related DB 350 and displayed so that the supervisor can confirm it as shown in (a) and (b) of FIG. 3 . .

The work DB 340 stores and manages various information related to excavation construction, such as an excavation work schedule, as well as information such as risk determination criteria for each event. For example, since bulldozers, forks, and other various excavation equipment (V) may injure the excavation personnel (AM) during movement and work, the excavation personnel (AM) are too close to the excavation equipment (V) Doing so may lead to various safety accidents. Therefore, a safety distance is defined between the excavation equipment (V) and the person involved in the excavation (AM), and the safety distance is set as work information and stored and managed. In addition, various safety accident-related regulations, working regulations, and regulations regarding the environment in the excavation tunnel can be set as work information.

The integrated management system of this embodiment further includes a CCTV (16). The CCTV 16 is installed in the excavation tunnel to take a video and generate and transmit video information, and the data processing module 320 of the remote server 300 transmits the video information received through the communication line as shown in FIG. ) is displayed through the monitoring module 330 as shown in the drawing.

The integrated management system of the present embodiment further includes a measuring instrument 19 installed in the excavation tunnel to generate and transmit measurement information by measuring the physical force on the tunnel. In addition, the data processing module 320 of the remote server 300 displays the measurement information received via the communication line through the monitoring module 330 as shown in FIG. 7 .

In general, the measurement of the physical force of the tunnel is made through a measuring instrument 19 installed after construction such as a shotcrete work or a rock bolt work performed in the excavation tunnel reinforcement process. At this time, the measuring instrument 19 is exemplified by a shock stress gauge, a rock bolt axial force gauge, an underground displacement gauge, and the like, and FIG. A cross-sectional image, (b) of FIG. 7 is a ground displacement state image displayed on the monitoring module 330, and (c) of FIG. 7 is a lock bolt output state image displayed on the monitoring module 330.

As described above, the integrated management system according to the present invention manages and supervises other comprehensive situations such as the state of the environment and physical force of tunnel excavation, the state and safety of the person involved in the excavation (AM) in the excavation tunnel, and the like in the remote server 300. In addition, it allows the field worker (M) to check and process the final scene survey process and collected information in real time.

Based on the integrated management system described above, the tunnel excavation method according to the present invention will be described in detail below.

For reference, the excavation official (AM) refers to a supervisor who operates the remote server 300 at the center, a field observer (M) who measures the final scene and collects information, and an excavation worker who performs excavation construction. By the way, below, the supervisor and the field observer (M) and the excavation worker will be separately described so that the technical description of the present invention is clear.

S10; excavation stage

The 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, as shown in the diagram (a) of FIG. 9 , the field observer M and the supervisor, etc. must be able to observe the makjangmyeon 21, so that the makjangmyeon 21 can be easily observed immediately after excavation. A blasting method that does not require the withdrawal of the excavation equipment (V) was applied. For reference, as shown in the drawing (b) of FIG. 9 , the excavation worker installs and explodes the charge 22 at a plurality of designated positions of the makjangmyeon 21 , and excavates the makjangmyeon 21 to the design depth.

When the last section is created through the explosion of the charge 22, as shown in (a) of FIG. 10, the bug 23 generated in the blasting process is transported from the excavation tunnel and removed, and the vehicle 110 of the MMS 100 is dead. This allows for unobstructed access to the section.

On the other hand, the scanners 14 and 15 installed along the excavation tunnel recognize the outgoing unique code of the identification terminal 18 carried by the person concerned with the excavation, and generate and transmit location information of the identification terminal 18 . In addition, the remote server 300 compares the location information and the unique code received through the communication line with the job information stored in the job DB 340, and if it corresponds to the prescribed location, the identification terminal 18 of the corresponding unique code Send guidance information. In addition, the identification terminal 18 outputs an alarm corresponding to the guide information through the speaker 18c and proceeds with the tunnel excavation process of the excavation worker.

S20; reinforcement stage

When the excavation is completed 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 a minimum basic process for preventing tunnel collapse immediately after blasting, and the basic process may include installation of rock bolts, installation of shockcrete, installation of steel supports, and the like. For reference, immediately after excavation by blasting, the ground of the excavation tunnel may be unstable. However, after excavation, the vehicle 110 and the field observer M of the MMS 100 enter the tunnel after excavation for observation and surveying of the final scene 21 of the excavation tunnel, so it is very important to reduce the risk of a collapse accident. To this end, after tunnel excavation, the internal structures 22a and 22b for ground reinforcement are installed to extend as much as the depth of excavation, as shown in the drawing of FIG. .

In addition, 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 enables not only the on-site observer (M) but also the remote supervisor to check in real time the final scene observation and survey situation and survey data of the excavation tunnel immediately after excavation, so the depth of the excavation tunnel extended in the excavation process Correspondingly, communication lines should be extended. Therefore, immediately after excavation, the internal structures 22a and 22b for installing the communication line are extended on the inner wall of the tunnel as shown in the drawing (b) of FIG. 10 . Communication lines constituting the communication lines, communication repeaters 12 and other frequency amplifiers (not shown) are selectively installed in the extended internal structures 22a and 22b.

Reinforcement steps of another implementation may proceed after the excavation step (S10), the communication line extension step (S30'), the MMS setup step (S40'), the makjangmyeon survey step (S50'), and the MMS withdrawal step (S60'). there is.

To explain this a little more, the communication line extension process is carried out immediately after excavation without any additional reinforcement construction in the excavation tunnel, followed by entering the MMS (100) tunnel, setting up the MMS (100), surveying the final scene, and withdrawing the MMS sequentially. Only after the progress is made to extend the internal structure 22 of the tunnel. Here, the internal structure 22 includes reinforcement construction such as support and shockcrete construction.

On the other hand, in the communication line extension step (S30'), after arranging communication lines such as communication repeaters 12 and 12' along the floor or installing structures such as wiring trays in a line on the inner wall of the excavation, the communication repeater 12 , 12'), etc., can be installed on top of a communication line.

S30; Communication line extension step

In order to enable wireless communication in the last section of the tunnel, the communication line between the communication repeater and the setup box is additionally extended along the extension of the excavation tunnel, so that communication with the communication line is possible in the last section of the excavation tunnel and unique code recognition is possible Scanners 14 and 15 are additionally installed.

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 connect and communicate with the remote server 300 online.
