Description

OSC modular movable rigid barrier system for underground roads

[0001] The present invention relates to an OSC modular movable rigid barrier system for underground roads.

[0002] A barrier is a facility that prevents vehicles from leaving the road and minimizes damage in the event of a vehicle collision. Depending on the installation location, it is classified into roadside, divider, sidewalk, and bridge use, and depending on the structural characteristics, it is divided into flexible barriers and rigid barriers.

[0003] The main function of a flexible barrier is to absorb impact energy while undergoing a certain range of structural deformation in the event of a vehicle collision. Representative examples include guardrails, guard pipes, and guard cables. On the other hand, a rigid barrier is a structure that focuses on minimizing deformation of the structure itself to guide the vehicle back to its path rather than absorbing impact. It is generally formed as an integral concrete structure.

[0004] The selection of the type of safety fence is determined based on the required safety performance criteria by comprehensively considering the road type of the installation site, traffic environment, type and speed of passing vehicles, etc. In general, the greater the structural rigidity, the better the escape protection performance of large vehicles, but the impact absorption performance is relatively low, which may reduce the passenger protection performance.

[0005] Accordingly, various structural improvement attempts are being made to achieve a balance between the vehicle's protective performance and the safety of passengers.

[0006] Meanwhile, protective structures installed inside tunnels have more structural and environmental constraints than those on general roads, so various considerations are required in their installation method and functional configuration.

[0007] This is because tunnels are closed structures with limited passage space, and the volume or shape of installations can interfere with vehicle traffic. In addition, material selection and installation structures that take into account the effects of lighting, visibility, fire safety, and ventilation systems are required.

[0008] In this regard, a prior art document on a prior art prepared to fundamentally prevent damage to a structure by constructing a protective wall on both sides of a tunnel entrance that has excellent shock absorption capacity and allows for quick and easy manufacturing, construction, and maintenance, thereby effectively absorbing, dispersing, and blocking the impact energy applied in the event of a vehicle collision, and minimizing damage to the vehicle, thereby minimizing human and material damage caused by such an accident, includes Korean Patent Publication No. 10-0255815 entitled “Protective wall for road tunnel entrance” (hereinafter referred to as “prior art”).

[0009] However, existing concrete material protective fences, including prior art ones, have been used by burying separate metal materials or reinforcing members inside the concrete for the purpose of improving protective performance or structural strength. However, since such reinforcement has been applied indiscriminately without comprehensively considering the shape, arrangement, and material characteristics related to structural performance, there has been a problem in which the performance improvement effect is minimal or the shock absorption performance is reduced due to fracture or scattering.

[0010] In addition, most existing concrete barriers, including prior art, are designed for outdoor road environments and are not suitable for special structures such as tunnels, which have large space constraints and complex environmental factors such as lighting, ventilation, and accessibility for maintenance. However, existing technologies remain in a simple arrangement method without structural design or functional supplementation that can meet these requirements, and as a result, they have limitations in not responding to practical needs such as ensuring safety and enhancing visibility in tunnels.

[0011] The present invention was created to solve the above problems, and the purpose of the present invention is as follows.

[0012] First, the purpose is to provide a movable rigid barrier for installation in tunnels that can prevent vehicle departure and induce stable vehicle behavior after a collision by securing strength performance and deformation performance in the event of a collision through the specification of the structure and specifications for each component.

[0013] Second, the purpose is to provide a protective fence with improved safety in terms of the degree of scattering and the distance of discharge of scattering products by optimizing the structural joint form and the arrangement conditions of components to minimize scattering due to breakage or detachment of components upon impact.

[0014] Third, the purpose is to provide a protective barrier that can reduce injuries to passengers and improve safety within the vehicle in the event of a collision through the dissipation characteristics of collision energy and the shape design of the protective structure.

[0015] Fourth, considering the special installation environment inside the tunnel, the purpose is to provide an intelligent protection system that can simultaneously secure visibility and maintenance efficiency by including a power receiving function and a light emitting module in the protection block and linking the power and light emitting status with the central control system to enable diagnosis.

[0019] In addition, the first reinforcing part includes an upper part of a '-' structure arranged on the upper part based on a '┌┐' structure using steel bars; and a column part that is connected by being inclined from the left end of the upper part in a ' / ' structure and is connected by being inclined from the right end of the upper part in a '\' structure to be symmetrical on the left and right; and the first reinforcing part is provided with a size ratio of a left-right reference length (L1) of the upper part, a vertical reference inclined length (L2) of the column part, and a left-right reference spaced length (L3) of the lower ends of the column part in the left and right directions, which is 145 mm to 150 mm (L1): 1170 mm to 1180 mm (L2): 520 mm to 425 mm (L3).

[0020] In addition, the lattice-shaped reinforcing structure formed on both left and right sides of the reinforcing structure is provided with a plurality of square frames forming a plurality of rows and columns through orthogonal cross-connections of the first reinforcing portion and the first reinforcing portion, and among the plurality of square frames, the square frames of the front row and the rear row based on the front-to-back direction are provided with a front-to-back reference length (D3) of 460 mm to 465 mm, the square frames of the remaining rows of the plurality of square frames are provided with a front-to-back reference length (D2) of 580 mm to 620 mm, and the plurality of square frames are provided with a tilted height (D4) based on the vertical direction of 290 mm to 310 mm.

[0021] And the protective block further includes a plurality of first reinforcing members, which are provided in a '-' structure using steel bars and are buried so as to be arranged at the left-right center of the protective block body on at least one height of each of the front and rear sides of the protective block body; and a second reinforcing member, which is provided in a '-' structure using steel bars and is buried so as to be arranged at the left-right center of the protective block body from the front to the rear of the protective block body on the upper side of the protective block body; and the diameter of the reinforcing bars of the plurality of first reinforcing members and the second reinforcing member is provided to be 26 mm to 32 mm.

[0040] 1. Description of the composition and structure of the OSC modular movable rigid barrier system for underground roads.

[0041] Referring to FIGS. 1 to 4, a system (1) using an OSC modular movable rigid protective fence (10) for an underground road of the present invention is installed on an underground road, such as the edge of a roadway in a tunnel, to prevent vehicle collisions and improve visibility and maintenance efficiency through light-emitting and status diagnosis functions. To this end, the system includes a movable rigid protective fence (10) that performs physical protection with a rigid structure in the event of a vehicle collision and has visibility and diagnostic functions by having a built-in power reception and light-emitting module, and a plurality of power transmission modules (20) that wirelessly supplies power to a protective block (100) and manages its operating status in conjunction with each other.

[0042] In more detail, the movable rigid protective fence (10) is configured to include a plurality of protective blocks (100) corresponding to at least two protective units arranged along the longitudinal direction of the front and rear; a connecting device (200); a steel bar member (300); a light-emitting module (400); and a power receiving module (500); so that the protective units arranged along the longitudinal direction of the front and rear are connected, thereby enabling the construction of an elongated protective structure.

[0043] These structural and compositional features are designed based on the OSC (Off-Site Construction) method, in which the main structural members, including the protective block (100), are precisely manufactured in advance at an external factory, and then installed on site through transportation and simple assembly.

[0044] That is, each protective block (100) is manufactured at the factory based on a certain standard and strength, so that quality deviation is minimized, and the light-emitting module (300) and power receiving module (400) are also pre-built or pre-configured in a modular state, so that electrical wiring work or additional installation processes on site can be significantly reduced.

[0045] In addition, the entire structure, including the connecting device for fastening between protective blocks, the pile insertion structure for securing ground fixation, and the power transmission / reception linkage system, is designed as a separate or sliding joint structure considering the OSC-based assembly system, providing advantages such as shortened construction time, minimization of work force, and night-time construction responsiveness.

[0046] In particular, the OSC method is very suitable for the implementation of this system in that it can satisfy the practical requirement of minimizing traffic restrictions due to construction, especially since it is installed at the edge of the roadway in a tunnel with a high traffic volume.

[0047] In addition, the OSC modular structure is excellent in terms of repeatability and maintenance efficiency, as it can be disassembled and reinstalled. In addition, even in the event of an accident or block damage, individual modules can be replaced or maintained, contributing to reducing downtime of the entire system and increasing operational stability.

[0048] The protective block (100) is a protective unit made of precast concrete to have a structure as shown in FIG. 5, and includes a protective block body (110), a reinforcing structure (120), a first reinforcing member (130), a second reinforcing member (150), a first fastening member (140), and a second fastening member (160).

[0049] Here, the protective block body (110) is a concrete segment forming the basic structure of the protective block (100), and has a central structure provided in a tapered shape in which the width from left to right becomes narrower as it goes upward.

[0050] Specifically, the protective block body (110) is provided with a size ratio of the front-back direction reference length (D), the vertical direction reference height (H), the left-right direction reference bottom width (W1), and the left-right direction reference top width (W2) as shown in FIGS. 5 and 6, which is 3000 mm (D): 1270 mm (H): 550 mm to 615 mm (W1): 180 mm to 250 mm (W2).

[0051] Most preferably, the protective block body (110) can provide optimal protective performance when it has a front-back standard length (D) of 3000 mm, a vertical standard height (H) of 1270 mm, a left-right standard bottom width (W1) of 610 mm, and a left-right standard top width (W2) of 200 mm.

[0052] In addition, the protective block body (110) is composed of a first body part (111) that corresponds to the lower region as shown in FIG. 6 and extends upwards with the same width from the left-right reference bottom width (W1), a second body part (112) that corresponds to the middle region and extends upwards in a tapered shape with a width that gradually narrows from the top of the first body part (111) to the level of the left-right reference bottom width (W1) and forms an integral part, and a third body part (113) that corresponds to the upper region and extends upwards in a tapered shape with a width that further narrows from the top of the second body part (112) and forms an integral part.

[0053] Specifically, based on 1270 mm corresponding to the vertical reference height (H) of the protective block body (110), the first body part (111) corresponds to an area up to a height (Ha) of 135 mm to 140 mm (most preferably 138 mm), the second body part (112) corresponds to an area having a height (Hb) of 160 mm to 170 mm from the top of the first body part (111) (most preferably 166 mm), and the third body part (113) corresponds to an area having a height (Hc) of 960 mm to 970 mm from the top of the second body part (112) (most preferably 966 mm).

[0054] In addition, the second body part (112) is formed so that the part connected to the upper end of the first body part (111) at the lower end has a curvature of R150 on the outside, and the part connected to the lower end of the third body part (133) at the upper end has a curvature of R260 on the inside.

[0055] In addition, the difference between the lower width and the upper width of the second body part (112), that is, the reduced width size, is 75 mm, and the difference between the lower width and the upper width of the third body part (113), that is, the reduced width size, is 113 mm.

[0056] The features regarding the structure and specifications of the protective block body (110) correspond to specific features for providing a high level of protective performance through fusion with other configurations to be described later.

[0057] And, in order to achieve connection between a plurality of protective blocks (100) arranged adjacently in the front and rear using a steel bar member (300), a connection member installation groove (110H) is provided on the inside (towards the bottom in the case of the front end, towards the front end in the case of the rear end) at the front and rear ends of the protective block body (110), as shown in FIGS. 4, 6, and 9.

[0058] In addition, as illustrated in FIG. 6, a pair of connecting device installation grooves (115H) open in the left-right direction are provided to connect a plurality of protective blocks (100) arranged adjacent to each other in the front and rear, using connecting devices (200) on both left and right sides symmetrical in terms of the height of the second reinforcing member (150) to be described later of the protective block body (110).

[0059] Next, the reinforcing structure (120) is a structure made of steel bars and is embedded with a specific structure inside the protective block body (110) to provide structural reinforcement. The level of structural reinforcement can be greatly improved through the specific structure constructed through the first reinforcing part (121) and the second reinforcing part (122).

[0060] First, the first reinforcing member (121) is provided in a '┌┐' structure using reinforcing bars having a reinforcing bar diameter of 10 mm to 16 mm (most preferably a standard of D13), and is a plurality of reinforcing bar structures arranged to be spaced apart from each other in the front-rear direction, and is buried as shown in FIGS. 5 and 7.

[0061] Specifically, the first reinforcing member (121) is composed of an upper part (121a) of a '-' structure placed on the upper part based on a '┌┐' structure using steel bars as illustrated in FIG. 5, and a pillar part (121b) that is connected by being inclined in a ' / ' structure from the left end of the upper part (121a) and by being inclined in a '\' structure from the right end of the upper part (121a) to be symmetrical on both sides, so that it most preferably has a structure of an isosceles trapezoid with the bottom side excluded as shown in FIG. 4.

[0062] Here, the first reinforcing member (121) is provided with a size ratio of the left-right reference length (L1) of the upper portion (121a), the up-down reference inclined length (L2) of the column portion (121b), and the left-right reference spaced length (L3) of the lower ends of the column portion (121b) in a range of 145 mm to 150 mm (L1): 1170 mm to 1180 mm (L2): 520 mm to 425 mm (L3).

[0063] Most preferably, the first reinforcing member (121) can provide optimal protective performance when the left-right reference length (L1) of the upper portion (121a) is 147 mm, the vertically inclined length (L2) of the column portion (121b) is 1177 mm, and the left-right reference distance (L3) of the lower portions of the column portion (121b) is 424 mm.

[0064] In addition, it is preferable that the first reinforcing member (121) be arranged in a form in which the upper portion (121a) of the side reference is positioned at a position (L4) spaced 70 mm downward from the upper surface of the third body part (113), as shown in FIG. 7, and the pillar portion (121b) is positioned at a position (L5) spaced 38 mm inward from the left and right sides of the third body part (113).

[0065] In addition, the second reinforcing member (122) is a plurality of reinforcing bar structures formed in a '-' structure using reinforcing bars having a reinforcing bar diameter of 10 mm to 16 mm (most preferably a standard of D13), and as shown in FIG. 5, it is connected to the left and right column parts (121b) of the plurality of first reinforcing members (121) in a vertical direction and spaced apart from each other, thereby forming a grid-like reinforcing structure on both left and right sides inside the protective block body (1110).

[0066] In addition, the second reinforcing member (122) is spaced apart from each other at equal intervals in the vertical direction perpendicular to the column portion (121b) of the first reinforcing member (121), and the distance (D4) at which the two are spaced apart at equal intervals is set to 290 mm to 310 mm.

[0067] Through this, a plurality of square frames forming a plurality of rows and columns are provided through orthogonal cross-connections (interconnected through welding depending on the implementation) of the column portion (121b) of the first reinforcing portion (121) and the second reinforcing portion (122), thereby forming a grid-like reinforcing structure on both left and right sides of the reinforcing structure (120).

[0068] Specifically, among the plurality of square frames formed through the orthogonal cross-connection of the column portion (121b) of the first reinforcing member (121) and the second reinforcing member (122), the square frames of the front row and the rear row based on the front-back direction are provided with a front-back reference length (D3) of 460 mm to 465 mm (most preferably 462.5 mm), and the square frames of the remaining rows among the plurality of square frames are provided with a front-back reference length (D2) of 580 mm to 620 mm (most preferably 600 mm).

[0069] In addition, a plurality of square frames formed through orthogonal cross-connections of the column portion (121b) of the first reinforcing member (121) and the second reinforcing member (122) are provided with a tilted height (D4) in the vertical direction of 290 mm to 310 mm (most preferably 300 mm).

[0070] The buried structure and standard features of the first reinforcing member (121) and the second reinforcing member (122) that constitute the reinforcing structure (120) are linked to the structural and standard features of the protective block body (110) described above, thereby achieving an improvement in protective performance.

[0071] In addition, the first reinforcing member (130) is a plurality of reinforcing bar structures made of a '-' structure using reinforcing bars having a reinforcing bar diameter of 26 mm to 32 mm (most preferably a standard of D29), and is installed so as to be positioned at the center of the left and right direction of the protective block body (110) at least one height above each of the front and rear sides of the protective block body (110) as shown in FIG. 5.

[0072] Specifically, the first reinforcing member (130) is provided in three pieces, one piece is placed on the front side of the protective block body (110) and two pieces are placed on the rear side. As shown in FIGS. 5 and 6, it is preferable that the first reinforcing member (130) placed on the front side of the protective block body (110) be placed at a height between the two first reinforcing members (130) placed on the rear side of the protective block body (110) in the vertical height direction.

[0073] In addition, the installation height (H1) of the first reinforcing member (130) disposed at the lower end of the first reinforcing member (130) disposed at the rear of the protective block body (110) is set to 350 mm, the installation height (H2) of the first reinforcing member (130) disposed at the front of the protective block body (110) is set to 500 mm, and the installation height (H3) of the first reinforcing member (130) disposed at the upper end of the first reinforcing member (130) disposed at the rear of the protective block body (110) is set to 650 mm, so that it is preferable that the intervals between the installation heights of each first reinforcing member (130) be 150 mm at equal intervals.

[0074] In connection with this, a first fastening member (140) for fastening a plurality of protective blocks (100) arranged adjacently in the front and rear using a steel bar member (300) is connected to the front end of the first reinforcing member (130) arranged in front of the protective block body (110) and the rear end of the first reinforcing member (130) arranged in the rear of the protective block body (110).

[0075] For this purpose, the first fastening member (140) includes a first coupler portion (141) and a first eye bolt portion (142).

[0076] First, the first coupler part (141) is a plurality of coupler modules that are connected to the front end of the first reinforcing member (130) embedded in the front side of the protective block body (110) among the plurality of first reinforcing members (130) and the rear end of the first reinforcing member (130) embedded in the rear side of the protective block body (110) among the plurality of first reinforcing members (130), as shown in FIGS. 8 and 9, respectively, and have a predetermined open space that is connected to the fastening member installation groove (110H) on the opposite side of the connection portion.

[0077] Next, the first eye bolt portion (142) is a plurality of eye bolt modules that are installed so as to be fastened to each of the plurality of first coupler portions (141) as shown in FIGS. 8 and 9 and placed within the fastening member installation groove (110H), and when installed, the steel rod insertion hole (142H) provided in the center is exposed in the vertical direction.

[0078] According to the implementation, the first coupler part (141) and the first eye bolt part (142) have a one-touch coupler type fastening structure so that when connected, the first eye bolt part (142) is pushed toward the first coupler part (141) to fasten at once, and the connection is not easily disconnected.

[0080] In addition, in the process of performing the fastening between a plurality of protective blocks (100) adjacently arranged in the front and rear using a reinforcing member (300), it is preferable that the installation positions of the front end of the first reinforcing member (130) arranged in front of the protective block body (110) and the first reinforcing member (130) arranged in the rear of the protective block body (110) do not overlap and are spaced apart from each other at equal intervals along the height in order to prevent the first eye bolt portion (142) of the first fastening member (140) coupled to the end of the first reinforcing member (130) from colliding with each other.

[0082] In connection with this, a second fastening member (160) is connected to the front and rear ends of the second reinforcing member (150) using a connecting device (200) to fasten a plurality of protective blocks (100) arranged adjacent to each other in the front and rear.

[0083] For this purpose, the second fastening member (160) includes a second coupler portion (161) and a second eye bolt portion (162).

[0087] Accordingly, the connecting device (200) that performs the connection by connecting one end of a front-end side protective block (100) among a plurality of adjacently arranged protective blocks (100) and the other end of a rear-end side protective block (100) includes a pair of connecting bodies (210), a pair of fastening plate structures (220), an upper plate structure (250), a first fastening member (230), and a second fastening member (240) as shown in FIGS. 4 and 8 to achieve connection using a connecting device installation groove (115H) and a second eye bolt portion (162).

[0088] Here, a pair of connecting bodies (210) are provided in a '┌┐' structure and are placed at the front and rear of each position where a pair of connecting device installation grooves (115H) are provided on the outer upper surface of the protective block body (110).

[0089] Through this, a pair of connecting bodies (210) are installed so that the lower part of the pillar portions placed vertically on the '┌┐' structure of the connecting body (210) covers the left and right ends of the connecting device installation groove (115H) as shown in FIGS. 4 and 8.

[0090] Next, the upper plate structure (250) is a plate structure arranged so that one end covers the upper surface of a connecting body (210) arranged on the rear end of one protective block (100) on the front side among a plurality of protective blocks (100) arranged adjacently in the front and back as shown in FIG. 8, and the other end covers the upper surface of a connecting body (210) arranged on the front end of another protective block (100) on the rear side among a plurality of protective blocks (100) arranged adjacently in the front and back.

[0091] Next, a pair of fastening plate structures (220) is a plate structure arranged so that one end covers the lower ends on both sides of the left and right sides of the connecting body (210) arranged on the upper rear end of one protective block (100) on the front side among a plurality of protective blocks (100) arranged adjacently in the front and back as shown in FIG. 8, and the other end covers the lower ends on both sides of the left and right sides of the connecting body (210) arranged on the front end of the other protective block (100) on the rear side among a plurality of protective blocks (100) arranged adjacently in the front and back.

[0092] In addition, the first fastening member (230) is configured for coupling between the upper surface of a pair of connecting bodies (210) and the upper plate structure (250) as shown in FIGS. 4 and 8, and is composed of a first connecting bolt portion and a first nut portion.

[0093] Specifically, the first connecting bolt portion of the first fastening member (230) is installed so as to penetrate the front and rear ends of the upper plate structure (250) and the upper surface of the connecting body (210) from the outside, and a first nut portion is fastened to both ends of the first connecting bolt portion installed in this manner.

[0094] Lastly, the second fastening member (240) is configured for connection between the lower left and right sides of a pair of connecting bodies (210), a pair of fastening plate structures (220), and the upper part of the protective block body (110), as shown in FIGS. 4 and 8, and is composed of a second connecting bolt portion and a second nut portion.

[0095] Specifically, the second connecting bolt portion of the second fastening member (240) is installed so as to penetrate the front and rear ends of the fastening plate structure (220) from the outside, the left and right ends of the connecting body (210), the connecting device installation groove (115H), and the connecting bolt insertion hole (162H) of the second eye bolt portion (162), and the second nut portion is fastened to both ends of the second connecting bolt portion installed in this manner.

[0096] According to the implementation, the protective block (100') may further include a first metal wire member (170') and a second metal wire member (180') to prevent it from being broken more easily upon collision with a vehicle, to prevent it from being pushed backwards by a certain distance due to a vehicle collision, and to prevent flying debris such as concrete fragments from being generated more upon collision with a vehicle and from flying far even if they are generated.

[0097] Specifically, as illustrated in FIG. 10, inside the concrete protective block body (110') corresponding to the basic structure of the protective block (100'), the protective performance improvement structure by the first reinforcing member (121') and the second reinforcing member (122') corresponding to the same as described above and the protective performance improvement structure by the first reinforcing member (130') and the second reinforcing member (150') are linked, and the first metal wire member (170') and the second metal wire member (180') are extended and wound in the longitudinal direction along the outer periphery of the first reinforcing member (130') and the second reinforcing member (150') can achieve a more reliable and advanced improvement in protective performance.

[0098] Here, the first metal wire member (170') is configured to be wound in a spring shape on the outside of a plurality of first reinforcing members (130') so that each of the plurality of first reinforcing members (130') is arranged at the center inside, and welding is performed at any number of points through a connecting bar in which one end is connected to the outside of the first reinforcing member (130') and the other end is connected to the inside of the first metal wire member (170') in order to be interconnected while the first reinforcing member (130') is arranged at the center.

[0099] More specifically, the first metal wire member (170') is a wire member having a diameter of 4 mm to 5 mm (most preferably 4.5 mm), and the diameter of the spring-shaped member formed by winding around the outer side of each of the plurality of first reinforcing members (130') is provided to be 190 mm to 210 mm (most preferably 200 mm).

[0100] In addition, the second metal wire member (180') is configured to be wound in a spring shape on the outside of a plurality of second reinforcing members (150') so that each of the plurality of second reinforcing members (150') is arranged at the center inside, and welding is performed at any number of points through a connecting bar in which one end is connected to the outside of the second reinforcing member (150') and the other end is connected to the inside of the second metal wire member (180') in order to be interconnected while the second reinforcing members (150') are arranged at the center.

[0101] More specifically, the second metal wire member (180') is a wire member having a diameter of 4 mm to 5 mm (most preferably 4.5 mm), and the diameter of the spring-shaped member formed by winding around the outer side of each of the plurality of second reinforcing members (150') is provided to be 190 mm to 210 mm (most preferably 200 mm).

[0102] Meanwhile, the light-emitting module (400, 400') is installed on at least one side of the left and right widthwise sides of the protective block (100) as shown in FIGS. 1 and 2, and provides a light source when in operation.

[0103] More specifically, the light emitting module (400) is installed in a space formed in a recess on the lower left outer surface of the protective block body (110) as illustrated in FIG. 1, and the light output direction of the light emitting module (400) located in this space is arranged in the form of a left-side lower slope so that it faces the road direction inside the tunnel, so that the light source is configured to be irradiated at a certain angle toward the road side.

[0104] In another way, the light emitting module (400') is installed in an installation groove or receiving space formed on the center or upper outer surface of the left side of the protective block body (110) according to the second embodiment as illustrated in FIG. 2, and the space is provided in a horizontal or predetermined inclination angle toward the front so that the light output direction of the light emitting module (400) is directed toward the roadway inside the tunnel, so that the light source is configured to be directly irradiated toward the roadway side.

[0105] In addition, the light emitting modules (400, 400') are inserted and fixed inside a housing having a light-transmitting cover on the inside to protect them from impact and contamination when exposed to the outside, and a plurality of light emitting modules (400) are installed at intervals so that the light they irradiate is continuously formed in the longitudinal direction along the road boundary line, thereby maximizing visibility in a tunnel at night or when the illumination level is low, and assisting in preventing or guiding a vehicle from leaving the lane.

[0106] In addition, the light-emitting module (400, 400') is configured to drive a built-in light-emitting element (e.g., LED) through wireless power provided from a power receiving module (500) to be described later, and may include a control function that is linked to a central control system so as to control the light-emitting intensity or whether to turn it on or off as needed.

[0107] And, power transmission modules (20) are installed in a plurality of places on the inner wall of the tunnel at predetermined intervals along the longitudinal direction of the tunnel, and each receives power from an external power supply means (P) that is electrically connected by wire.

[0108] Specifically, the power transmission module (20) is installed in the built-in space or buried structure of the tunnel wall, and is configured in multiples arranged at regular intervals, and each transmission module has a structure that is electrically wired to a common external power supply means (P) and can be driven at all times or according to a control signal.

[0109] At this time, the power transmission module (20) transmits power by magnetic induction or magnetic resonance based on wireless power transfer (WPT) technology, and a directional transmission coil that is easy to align with high precision can be applied so that stable power transmission is possible even in a state of relative alignment with a protective block located within the transmission range.

[0110] In connection with this, the power receiving module (500) is installed in the protective block body (110) and is electrically and wirelessly connected to an adjacent power transmitting module (20) among a plurality of power transmitting modules (20) to receive power and supply operating power for operation to the light emitting module (400).

[0111] To this end, the power receiving module (500) includes a power receiving unit (510), a light emitting control unit (520), a first operating state detection unit (530), a second operating state detection unit (540), and a communication unit (550) as illustrated in FIG. 3.

[0112] Here, the power receiving unit (510) receives AC power transmitted from an adjacent power transmitting module (20) in a wireless power transfer (WPT) manner, and includes a rectifying circuit and a stabilizing circuit that convert it into DC power suitable for driving the light emitting module (400).

[0113] Next, the light emitting control unit (520) receives power output through the power receiving unit (510), outputs a lighting signal to the light emitting module (400), and controls various light emitting conditions such as blinking cycle, brightness control, and preliminary inspection function.

[0114] Depending on the implementation, the light emission control unit (520) can adjust the light emission mode according to the external environment in conjunction with a light sensor or a time-based algorithm.

[0115] In addition, the first operating status detection unit (530) detects the status of the voltage and current received from the power receiving unit (510), determines whether reception has occurred and whether the reception quality is within a normal range, and generates first analysis information regarding the power reception status.

[0116] The first analysis information generated in this way is used to determine the connection status with the power transmission module (20), wireless transmission and reception efficiency, etc.

[0117] In addition, the second operating state detection unit (540) determines the electrical state in which power is transmitted from the light-emitting control unit (520) to the light-emitting module (400) and whether actual light output is being generated from the light-emitting module (400), thereby generating second analysis information regarding the light-emitting state.

[0118] In addition, the second operating status detection unit (540) is configured to comprehensively analyze whether there is an abnormality in the light-emitting circuit, the aging status of the light-emitting element, and the standard deviation of the output light amount.

[0119] Lastly, the communication unit (550) is connected to the central control server (S) based on a wireless network, and transmits the first analysis information and the second analysis information generated by the first operation status detection unit (530) and the second operation status detection unit (540) to the control server (S) at regular intervals or according to event conditions, and receives the light emission control signal received from the control server (S) and transmits it to the light emission control unit (520), thereby enabling remote control of the operating conditions of the light emission module (400).

[0120] In addition, the central control server (S) is configured to receive the first analysis information and the second analysis information, analyze the information, and perform various remote management functions such as status diagnosis of the overall operating status of the protection block, abnormality detection, and establishment of a maintenance plan.

[0121] For example, if power reception is not detected for a certain period of time in a specific protection block through the first analysis information, the server (S) can determine whether there is a possibility of a failure in the power transmission module (20) or a malfunction in the receiving unit (510) and send a notification to the maintenance manager or classify the power status of the relevant section as a priority inspection target.

[0122] In addition, if the light output of the light emitting module (400) is below the standard illuminance or an irregular lighting pattern is detected based on the second analysis information, aging or damage of the light emitting element or a control error of the light emitting control unit (520) may be suspected, and the corresponding protective block may be automatically registered as a maintenance target or replacement priority.

[0123] In this way, the control server (S) can comprehensively manage the status of the entire defense system through the received analysis information, and apply diagnostic logic such as identifying the location of anomalies, analyzing failure patterns, and predicting component lifespan.

[0124] Meanwhile, the control server (S) can generate a light-emitting control signal based on real-time status analysis or preset conditions and transmit it to the corresponding protection block (100) through the communication unit (550).

[0125] This light control signal may be composed of a normal lighting signal after a normal state check, a blinking pattern signal for an area classified as a caution zone, a forced lighting signal or blinking speed adjustment signal in an emergency situation, and a light intensity control signal for application to a specific time zone (e.g., night / night light mode).

[0126] These light-emitting control signals are interpreted by the light-emitting control unit (520) to change the operating conditions of the light-emitting module (400) such as the lighting cycle, blinking pattern, and brightness in real time, and, depending on the judgment of the control server (S), it is possible to perform synchronized control methods such as sequential lighting, group control, and pattern linkage control not only for individual protection block units but also for multiple consecutive sections.

[0127] Accordingly, the system's responsiveness and flexibility are significantly improved in various usage scenarios, such as warning of danger in specific sections within tunnels, guiding emergency vehicle passage, and ensuring visibility at night.

[0128]

[0129] 2. Description of performance test of movable rigid barrier for installation inside tunnels

[0130] The tests below were conducted to examine safety in the event of a vehicle collision by performing a collision simulation based on a movable rigid protective fence (10) for installation inside a tunnel according to the present invention, which is composed of a plurality of protective blocks (100); a connecting device (200); and a steel bar member (300); as described above, and in which the protective blocks (100) are connected and connected along the longitudinal direction in the front and rear directions.

[0131] Here, a plurality of protective blocks (100) of a movable rigid protective fence (10) for installation inside a tunnel to be inspected include a protective block body (110), a reinforcing structure (120), a first reinforcing member (130), a second reinforcing member (150), a first fastening member (140), and a second fastening member (160), and are manufactured in accordance with the most desirable specifications and structural conditions described above.

[0132] Specifically, the test items were strength performance for large vehicle collisions and passenger safety for small vehicle collisions. The review method was to conduct a crash simulation considering SB1 class crash conditions in accordance with the performance evaluation method of vehicle safety fences in the Road Safety Facility Installation and Management Guidelines (Ministry of Land, Infrastructure and Transport, 2014) and the Vehicle Protection Safety Facility Real Vehicle Crash Test Work Manual (Ministry of Land, Infrastructure and Transport, 2015).

[0133]

[0134] (1) Strength performance evaluation

[0135] The results of the strength performance evaluation are as shown in Table 1 below.

[0136] Item Performance Standard Simulation Results Structural Performance Strength Performance Strength will be maintained Has strength that trucks will not break through. Deformation Performance <Maximum Deformation> Concrete foundation: 0.3 m or less Pillars embedded in the soil: 1.0 m or less Maximum Deformation: 0.26 m Maximum Occupancy Width: 0.26 m Behavior of the vehicle after collision There will be no overturning of the vehicle The center of gravity of the vehicle will not invade the center line of the safety fence Escape Box Escape into the box Component Scatter Component members will not scatter onto or off the road and cause harm to passengers or third parties There will be no large scattering of component members in the event of a vehicle collision.

[0137] As shown in Table 1, the final deformation of the movable rigid barrier (10) for tunnel interior installation according to the present invention was 0.26 m, and the maximum width occupied by the vehicle during the collision was 0.26 m. Accordingly, the center of gravity of the colliding vehicle did not infringe upon the center of the vehicle barrier, and although the wheels of the vehicle did not completely leave the escape box during the analysis time, it was predicted that the boundary would not be infringed upon based on the vehicle's travel path.

[0138] In addition, no abnormal behavior such as vehicle overturning was observed in the overall collision behavior, and the main damage to the movable rigid barrier (10) for tunnel interior installation according to the present invention after a collision with a large vehicle was a tensile crack on the opposite side of the collision of the protective block (100) that initially collided, and only a partial damage to the concrete occurred at the end of the protective block (100) near the collision site.

[0139]

[0140] (2) Passenger protection performance evaluation

[0141] The results of the passenger protection performance evaluation are as follows in Table 2.

[0142] Item Performance Standard Simulation Results Occupant Protection Performance THIV 33km / h or less 19.5km / h PHD 20g or less 7.7g ASI (reference) 0.98 Vehicle Safety Performance after Collision There will be no vehicle overturning, etc. The rotation angle of Roll and Pitch will be 75° or less Roll: 4.9°, Pitch: 8.6° Escape Box Escape within the box Component Flying Component will not fly onto or off the road and cause harm to passengers or third parties There will be no large flying of component parts in the event of a vehicle collision.

[0143] As shown in Table 2, the THIV, which is the occupant safety index of the movable rigid barrier (10) for tunnel interior installation according to the present invention, was 19.5 km / h, which is below the performance standard of 33 km / h, and the PHD was 7.7 g, which is below the performance standard of 20 g. The ASI used in European standards was 0.98. Accordingly, the maximum rotation angle of the vehicle during the collision was Roll: 4.9°, Pitch: 8.6°, which is below the performance standard of 75°. The escape box for evaluating the vehicle behavior after the collision showed that the vehicle's wheels were separated into the escape box, and no abnormal behavior such as the vehicle overturning was observed in the overall collision behavior.

[0144] As a result, it can be seen that the movable rigid protective fence (10) for tunnel interior installation according to the invention has a considerably high level of protective performance based on the characteristics of the specific structure and specifications of the detailed configuration when based on a plurality of protective blocks (100), and further, when the first metal wire member (170') and the second metal wire member (180') are further added according to implementation, not only the degree of rigidity but also the degree of scattering and the degree of scattering distance can be further reliably improved.

[0145] The embodiments disclosed in the present invention are intended to illustrate, not limit, the technical concepts of the present invention. These embodiments do not limit the scope of the technical concepts of the present invention. The scope of protection should be interpreted according to the following claims, and all technical concepts within the scope equivalent thereto should be construed as being included within the scope of the present invention.
