Description

Informatization integrated management system and excavation construction method of tunnel construction site {MULTILATERAL INTEGRATED MANAGEMENT SYSTEM AND TUNNEL EXCAVATION METHOD ON CONSTRUCTION SITE}

The present invention relates to an information integrated management system and an excavation construction method of a tunnel construction site. More specifically, by grasping the condition of the tunnel construction site in real time and integrated management, a remote supervisor can also grasp and manage the work environment at once. It relates to an integrated system and excavation construction method that can check and cooperate with field observers in real time, as well as observation and surveying of the last scene.

Tunnel excavation is indispensable in the construction of roads or railroads passing through mountainous terrain. Tunnel excavation is typically drilled and charged, blasted and ventilated. The process follows the NATM (New Austrian Tunneling Method) technique such as support and pumice treatment, shock concrete pouring, support and rock bolt installation, and concrete lining.

Such tunnel excavation construction requires a large number of professional personnel to perform the above process, a long construction period, and a large consumption budget. In addition, tunnel excavation excavates rock mass such as mountainous terrain, and blasting work is performed for excavation.After blasting, workers are put into the tunnel created by blasting under unstable ground conditions and environmental conditions to perform various tasks such as reinforcement work. Because it must be done, the work environment is very dangerous. Therefore, a method and various systems for confirming and managing the safety of workers and the stability of the excavation tunnel were eagerly required.

On the other hand, for safer and more effective blasting work, it was necessary to accurately identify the rock mass of the excavation target, design blasting to prevent collapse, and prepare various reinforcement works. In general, rock masses are determined by grasping the distribution of rocks, carcinomas, and joints, and the condition of the curtain surface to be generated by the subsequent excavation can be predicted based on the curtain surface created by the previous excavation. Therefore, for a more accurate, objective, and reliable rock determination, it is possible only by collecting various information on the scene accurately in the field and making the determination by a large number of professional personnel.

For rock determination and prediction, in the past, the observer directly collects various data such as filming or curves that occurred after the blasting process at the site and makes rock determination, or after the observer collects only data, it is transmitted to a remote supervisor. Thus, the black judgment was made.

However, in the related art, data collection and data processing is performed only on the arbitrary judgment of the field observer, so the collected data and the dark judgment result were subjective and not highly reliable. In addition, even if the rock determination is performed separately by professional supervisors, the field observer must transfer the collected data to a remote center at a time lag, so the time required for data collection and rock determination has increased, and the supervisor is collected by the field observer. Since the dark decision should have been made based only on the collected data obtained from the year, the supervisor's dark decision result also had a limit in having complete objectivity.

In order to solve this problem, conventionally, a method has been proposed in which a communication equipment is provided at the entrance of an 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 this conventional method, as the depth of the excavation tunnel increases, the movement distance of the field observer for transmitting the collected data increases, and this delays the monitoring time of the supervisor for supplemental and additional collection of collected data. It was not possible to completely solve the increase in the time required for the determination of the rock. In addition, when collecting data related to the scene, the supervisor could not supervise the field observer or directly identify and collect the desired data, so there was still a problem that he had to rely only on the data collected by the field observer to make a dark decision.

Moreover, if a decision is needed during field work such as close-up observation or an urgent dark decision is required, the field observer should stop the collection work and visit a remote center in person to interview and discuss with the supervisor. Judgment work time occupied a significant portion of the excavation work period.

It is possible to connect and achieve. The setup box 11 is an interface for Internet access and is installed at the entrance of the excavation tunnel. Meanwhile, 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 manner, or a wired or wireless method.

The communication line is extended in stages whenever the excavation work is performed in stages, so that the 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 survey data by measuring the last scene of the excavation tunnel, and is controlled in operation according to an operation signal received through the communication line. In the MMS 100, a variety 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 the field observer or the remote server 300, the last scene of the excavation tunnel Survey. For the last scene measurement, the MMS 100 may be equipped with various types of measurement devices 120 for 3D surface analysis of the last scene. Typically, a Lidar (Laser Radar, Light Detection And Ranging) or one or more A PTZ camera (Pan-Tilt-Zoom Camera) and the like may be exemplified. Here, the PTZ camera allows one or two or more of a point on the film scene to be photographed at various angles and aiming angles at different positions, thereby making it three-dimensional through a screen combination. For reference, when the PTZ camera is implemented by 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 position at the curtain surface. The focus laser may form a target for grasping a photographing distance and an appropriate position on the film surface, so that the PTZ camera may take a photograph using a target as a reference point, and synthesize a photographed 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, an illumination device 130 for optical photography can be added, and when the survey device 120 is a lidar, an image image of the last scene and the last section In order to collect, a photographing device 140 such as a general digital camera or a video camera may be additionally installed.

In addition, the MMS 100 further includes a transmission/reception device 150 for transmitting the survey data generated by the surveying device 120 and the photographing device 140, and receiving a manipulation signal from the outside. In addition, the MMS 100 further includes a controller 160. The controller 160 processes the information collected by the survey device 120 and the photographing device 140 to generate survey data, and the control mobile 200 and the remote server 300 through the transmission/reception device 150 It transmits to one or more selected, and controls the operation of the measuring device 120 and the photographing device 140 according to the manipulation signal.

It is composed of a control module (18d) to be output, and is carried by the person involved in the excavation (AM). The identification terminal 18 is a safety means for sending a unique code to identify the location of the excavation official (AM) in the excavation tunnel, and guiding the dangerous situation from the remote server 300 to the excavation official (AM) in which a dangerous situation has occurred. to be. In general, it is recommended that the excavation officials (AM) be additionally configured on small items that can be carried at all times, and are preferably installed in a hard hat or a 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, communicates with the communication line at the end of the excavation tunnel according to the tunnel length deepening according to the excavation, and recognizes the unique code. It is additionally installed to enable this.

The scanners 14 and 15 recognize the unique code sent from the identification terminal 18 while scanning the inside of the tunnel at all times or periodically, and identify corresponding location information. For reference, even in the last section in which the tunnel is created through excavation, the excavation official (AM) must be identified and identified, so the scanners 14 and 15 are additionally installed like a communication line whenever the tunnel is additionally excavated.

Meanwhile, the scanners 14 and 15 have different functions depending on the installation location. Since the scanner 14 installed at the entrance of the tunnel allows the excavation personnel (AM) to check the entrance and exit of the tunnel, the supervisor at the remote center as shown in Figure 3 (a) and (c) It is possible to check whether or not, whether or not to shift, whether the field observer enters or withdraws. A number of scanners 15 installed inside the tunnel identify the locations of the excavation personnel (AM) scattered throughout the excavation tunnel (see Fig. 3 (c) and 5), and work of the excavation officials (AM) in operation. It is possible to check whether the position is displaced and whether a working vehicle such as a bldozer is close. In addition, as shown in (b) of FIG. 3, the person concerned with the excavation (AM) in which an emergency situation has occurred and the location thereof are quickly identified and notified by the person in charge and the supervisor of the center, so that it is possible to respond quickly to the emergency situation.

The remote server 300 stores the observation DB 310 for storing and managing the survey data received from the MMS 100, the related DB 350 for storing and managing identification information of the person involved in the excavation (AM), and the work information. It transmits the management operation DB 340 and 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.

To describe each component of the remote server 300 in more detail, the observation DB 310 includes survey data received from the MMS 100 as well as additional data generated by field observers and supervisors based on the survey data. By storing and managing the back, it is used as the base data that enables experts to finally predict the rock quality, carcinoma, and joint distribution of the rock mass.

The person concerned DB 350 manages and stores identification information about the person concerned with excavation (AM) for each unique code. Therefore, when the unique code is received from the scanners 14 and 15, the relevant identification information can be retrieved from the related DB 350 and displayed so that the supervisor can check 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 criteria for determining whether there is a risk for each event. For example, because the bulldozer, forkrain, and other various excavation equipment (V) may injure the excavation personnel (AM) during the movement and work process, the excavation personnel (AM) is too close to the excavation equipment (V). Doing so can lead to various safety accidents. Therefore, the safety distance between the excavation equipment (V) and the excavation personnel (AM) is defined, and the safety distance is set as work information and stored and managed. In addition, various safety accident related regulations, working regulations, and regulations related to the environment in the excavation tunnel can be set as work information.

The integrated management system of this embodiment further includes a CCTV (16). CCTV 16 is installed in the excavation tunnel to generate and transmit image information by photographing a video, and the data processing module 320 of the remote server 300 receives the image information received through the communication line (a ) Display through the monitoring module 330 as shown in the figure. Eventually, the supervisor can visually check the current situation of the excavation tunnel in the center, and through this, the supervisor can respond quickly to various situations.

In the tunnel excavation method of this embodiment, the scanners 14 and 15 installed along the excavation tunnel recognize the origination unique code of the identification terminal 18 carried by the person concerned with the excavation, and generate and transmit the location information of the identification terminal 18. , When the remote server 300 compares the location information and the unique code received through the communication line with the job information and corresponds to the specified location, it transmits the guidance information to the identification terminal 18 of the corresponding unique code, and the identification terminal ( 18) a tunnel excavation step (S10) in which an alarm corresponding to the guide information is output through the speaker 18c and the tunnel excavation of an excavation person is in progress; In order to enable wireless communication in the last section of the tunnel, a communication line between the communication repeaters 12 and 12' and the setup box 11 is further extended along the extension of the excavation tunnel, and the communication line and the communication line in the last section of the excavation tunnel Communication line extension step (S30) in which the scanner (14, 15) is additionally installed to enable communication and to recognize the unique code; The MMS (Multi-sensor Measuring System) 100) mounted on the vehicle 110 enters the last section, and the control mobile 200 and the MMS 100 of the excavation observer (AM) communicate with the communication repeaters 12, 12' MMS setup step (S40) of connecting and communicating with the remote server 300 via ); MMS (S40) surveys the last scene (21, 21', 21") of the excavation tunnel and transmits the collected survey data to the remote server 300, and the control mobile 200 receives the survey data. Step (S50); MMS withdrawal step (S60) in which the MMS 100 is withdrawn from the last section for subsequent excavation of the excavation tunnel; and includes.

For reference, the excavation official (AM) refers to the supervisor who operates the remote server 300 in the center, the field observer (M) who measures the scene and collects information, and the excavation worker who performs excavation construction. By the way, hereinafter, the supervisor, the field observer M, and the excavation worker will be separated and described so that the technical description of the present invention becomes clear.

S10; Excavation stage

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. The tunnel excavation method of this implementation requires that the field observer (M) and the supervisor can observe the curtain surface 21 as shown in (a) of FIG. 9, so that the curtain surface 21 can be easily observed immediately after excavation. To ensure that the excavation equipment (V) is not removed, a blasting method was applied. For reference, as shown in (b) of FIG. 9, the excavation worker installs and explodes the charging agent 22 at a number of designated locations on the curtain surface 21, and excavates the curtain surface 21 to a design depth.

When the last section is created through the explosion of the charging (22), the burr (23) generated in the blasting process is removed from the excavation tunnel as shown in (a) of FIG. 10, and the vehicle 110 of the MMS (100) is closed. Make sure to enter the section without jamming.

On the other hand, scanners 14 and 15 installed along the excavation tunnel recognize the origination unique code of the identification terminal 18 carried by the person concerned with the excavation, and generate and transmit the location information of the identification terminal 18. In addition, the location information and the unique code received through the communication line are compared with the work information stored in the work DB 340 by the remote server 300, and if they correspond to the prescribed location, the identification terminal 18 of the corresponding unique code is Transmit guidance information. In addition, the identification terminal 18 proceeds with the tunnel excavation process of the excavation worker while outputting an alarm corresponding to the guide information through the speaker 18c.

Therefore, the remote server 300 checks all the conditions of the excavation worker during the excavation process and notifies the supervisor, and the supervisor collects, manages and supervises the safety and other various information of the excavation worker.

S20; Reinforcement steps

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 a rock bolt, installation of shockcrete, installation of steel beams, and the like. For reference, immediately after excavation by blasting, the ground of the excavation tunnel may be unstable. However, after excavation, it is very important to reduce the risk of a collapse accident because the vehicle 110 of the MMS 100 and the field observer M enter the tunnel after excavation in order to observe and measure the curtain surface 21 of the excavation tunnel. To this end, after tunnel excavation, the internal structures 22a and 22b for reinforcing the ground are extended by the depth of the excavation as shown in Fig. 10(b), so that the field observer M can safely observe and measure the dead end. .

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 internal structures 22a and 22b. Can be. The tunnel excavation method of the present invention enables real-time confirmation of the last scene observation and surveying situation and survey data of the excavation tunnel immediately after excavation, so that the field observer (M) as well as the remote supervisor can check the depth of the excavation tunnel extended in the excavation process. In response, the communication line must be extended. Therefore, immediately after excavation, the internal structures 22a and 22b for communication line installation on the inner wall of the tunnel are extended as shown in FIG. 10(b). In the extended internal structures 22a and 22b, a communication line constituting the communication line, a communication repeater 12, and other frequency amplifiers (not shown) are selectively installed.

The reinforcement step of another implementation may be performed after the excavation step (S10), the communication line extension step (S30'), the MMS setup step (S40'), the last surface survey step (S50'), and the MMS withdrawal step (S60'). have.

In more detail, after the excavation, the communication line extension process proceeds immediately without any additional reinforcement construction in the excavation tunnel, followed by entering the MMS (100) tunnel, setting up the MMS (100), measuring the last scene, and withdrawing the MMS in sequence. Only after proceeding, the internal structure 22 of the tunnel is extended. Here, the internal structure 22 includes reinforcement works such as support and shockcrete construction.

Meanwhile, in the communication line extension step (S30'), communication lines such as communication repeaters 12 and 12' are arranged along the floor, or structures such as wiring trays are installed in a row on the inner wall of the excavation, and then the communication repeater 12 , 12'), etc. can be installed on top.

S30; Communication line extension stage

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 further extended along the extension of the excavation tunnel, and communication with the communication line in the last section of the excavation tunnel is possible 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. 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 manner, or a wired or wireless method.

In the case of the wired method, the communication repeater 12 is installed at a location where wireless communication is possible in the last section, and the communication line drawn from the setup box 11 is wired along the excavation tunnel to be connected to the communication repeater 12.
