Description

Technology Field

[0001] The present disclosure relates to a soundproof tunnel capable of blocking flame propagation in the center of a two-way driving lane. Background Technology

[0002] Generally, a soundproof tunnel can be defined as a roofed structure that blocks or reduces noise as a tunnel-type soundproofing facility. Since the top and the left and right sides of a soundproof tunnel are completely sealed with soundproof panels, excluding the entrance and exit, it is possible to simultaneously block both direct and diffracted sound generated from the road. Unlike ordinary tunnels, which are mainly located in underground spaces in mountainous areas, soundproof tunnels are installed above roads that pass through urban sections where high-rise buildings are densely concentrated.

[0003] However, there are currently no installation or quality regulations regarding the fire safety of soundproof tunnels, and prior research has also focused primarily on noise reduction effects. Consequently, most soundproof tunnels are constructed using H-shaped steel structures with PC (Polycarbonate) sound panels—a thermoplastic—for the sake of shortened construction time and ease of work; as a result, they pose a relatively higher risk compared to standard tunnels in the event of a disaster, such as a fire inside the tunnel.

[0004] In particular, in soundproof tunnels with driving lanes on both sides, if a fire occurs in one lane, flames can spread to the other lane, causing significant casualties and damage to vehicles and facilities. Therefore, measures must be devised to prevent the spread of fire in soundproof tunnels with driving lanes on both sides.

[0005] The background technology for this invention is Korean Registered Utility Model No. 20-0472066 (Patent Document 1), which proposes a "soundproof tunnel with driving lanes on both sides." This utilizes a pipe-shaped frame to perform the functions of a soundproof tunnel's framework, exhausting contaminated air inside the tunnel, and sound absorption. It is equipped with a ventilation fan to increase air purification efficiency by exhausting and ventilating contaminated air inside the tunnel, and utilizes a smoke control boundary wall to prevent the spread of soot or smoke generated in the event of a fire inside the tunnel. However, this background technology has a problem in that, in the case of a soundproof tunnel with driving lanes on both sides, relying solely on a smoke control boundary wall cannot prevent the spread of flames to the other lane side when a fire occurs on one driving lane side.

[0006] Another background technology of the present invention is Korean Registered Patent No. 10-1071209 (Patent Document 2), which proposes a "soundproof tunnel equipped with an exhaust door." This design provides a soundproof function by closing the top of the tunnel under normal conditions, while allowing for rapid ventilation of the interior by installing a door member that opens the top of the tunnel in the event of a fire. However, when this background technology is applied to a soundproof tunnel with two driving lanes, the ventilation capacity of the door member alone is insufficient to completely prevent the spread of flames to the other lane when a fire occurs on one driving lane side.

[0040] FIG. 1 is a cross-sectional view illustrating a soundproof tunnel according to one embodiment of the present disclosure, FIG. 2 is a plan view of a part of FIG. 1, FIG. 3 is an enlarged view of part 'E' of FIG. 2, FIG. 4 is a drawing illustrating an intermediate partition according to one embodiment of the present disclosure, FIG. 5 is an enlarged view of part 'C' of FIG. 1, and FIG. 6 is an enlarged view of part 'D' of FIG. 1.

[0041] Referring to FIGS. 1 to 4, a soundproof tunnel (10) according to one embodiment of the present disclosure comprises a pair of main pillars (21) installed upright on main foundation concrete (20) installed at a certain distance on both sides of a road (1), a roof truss beam (30) connected to the upper ends of the pair of main pillars (21), a roof cover (40) connected to the roof truss beam (30), a central foundation concrete (50) installed longitudinally along the road (1) in the height direction of the road (1) at the center of the pair of main pillars (21), a central pillar connecting bracket (51) installed at a predetermined interval on the upper surface of the central foundation concrete (50), a central pillar (52) whose lower end is connected to the central pillar connecting bracket (51) and whose upper end is connected to the roof truss beam (30), and a space separation of the left and right driving lanes (1a, 1b) of the road (1) installed between adjacent central pillars. It includes an intermediate partition (60) that performs the task.

[0042] The roof truss beam (30) may be composed of multiple steel pipes. The roof truss beam (30) may include an upper chord (31), a lower chord (32), and an inclined member (33) connecting the upper chord (31) and the lower chord (32).

[0043] The road (1) can be divided into a left driving lane (1a) and a right driving lane (1b) based on the central foundation concrete (50). The left and right driving lanes (1a, 1b) can have different directions of travel for vehicles.

[0044] The intermediate partition (60) can perform spatial separation of the left and right driving lanes (1a, 1b) by dividing the interior of the soundproof tunnel (10) into left and right sides. The intermediate partition (60) can close the space of the left and right driving lanes (1a, 1b) except for the entrance and exit of the soundproof tunnel (10). This intermediate partition (60) may include at least one of a membrane material, a soundproof plate, and a corrugated steel plate.

[0045] Therefore, if a fire caused by a vehicle occurs in one of the driving lanes, the flame propagation is blocked by the intermediate partition (60), thereby preventing damage to vehicles and people traveling in the other driving lane.

[0046] The central support (52) can be provided to reduce the load burden applied to the soundproof tunnel (10). Referring to FIGS. 5 and 6, the upper end of the central support (52) can be rotatably hinged to the roof truss beam (30), and the lower end can be rotatably hinged to the central foundation concrete (50).

[0047] For hinge connection between the roof truss beam (30) and the upper part of the central support (52), a first hinge bracket (34) may be installed on the roof truss beam (30), and a second hinge bracket (53) may be installed on the upper part of the central support (52). The first hinge bracket (34) and the second hinge bracket (53) can be rotated relative to each other by being connected by an upper hinge pin (54). The upper hinge pin (54) can be connected by passing through the first hinge bracket (34) and the second hinge bracket (53).

[0048] For hinge connection between the bottom of the central support (52) and the central foundation concrete (50), a third hinge bracket (55) may be installed at the bottom of the central support (52), and a central support connecting bracket (51) may be installed on the central foundation concrete (50). The central support connecting bracket (51) may include a base plate (51a) that is connected to the central foundation concrete (50), and a fourth hinge bracket (51b) that extends from the base plate (51a).

[0049] The third hinge bracket (55) and the fourth hinge bracket (51b) can rotate relative to each other by being joined by a lower hinge pin (56). The lower hinge pin (56) can be joined by passing through the third hinge bracket (55) and the fourth hinge bracket (51b).

[0050] Accordingly, since the upper and lower ends of the central support (52) are both hinge-connected, the moment applied to the central foundation concrete (50) by the external force applied to the central support (52) is reduced, thereby reducing the load burden on the central foundation concrete (50), and as a result, the size of the central foundation concrete (50) can be minimized, making economical construction possible.

[0051] FIG. 7 is a drawing illustrating the connection between a central support and a central foundation concrete according to another embodiment of the present disclosure.

[0052] Referring to FIG. 7, the lower end of the central support (52) can be connected to allow rotation and vertical movement so as to ensure excellent structural stability against the load applied to the soundproof tunnel (10).

[0053] To this end, the central support connecting bracket (51) may be provided with an elongated hole (51c) that is long in the vertical direction. The elongated hole (51c) may be provided in the fourth hinge bracket (51b) of the central support connecting bracket (51). The lower hinge pin (56) can rotate while sliding up and down along the elongated hole (51c) by passing through the elongated hole (51c) and the third hinge bracket (55) and being joined. That is, the lower end of the central support (52) can be connected to the central support connecting bracket (51) via a slip hinge through the connection between the elongated hole (51c) on the central support connecting bracket (51) side and the lower hinge pin (56), and the upper end of the central support (52) can be connected via a fixed hinge through the upper hinge pin (54) connected to the first hinge bracket (34) connected to the roof truss beam (30) and the second hinge bracket (53) connected to the upper end of the central support (52).

[0054] Accordingly, the moment applied to the central support (52) can be minimized by the rotation of the lower hinge pin (56), and the vertical load applied to the central support (52) can be minimized by the vertical movement of the lower hinge pin (56). That is, as the central support (52) slides through the slip hinge in response to the vertical displacement of the roof truss beam (30), even if vertical displacement of the roof truss beam (30) occurs, the vertical load on the central foundation concrete (50) is not increased due to the forced downward movement of the central support (52), thereby further minimizing the size of the central foundation concrete (50) and enabling economical construction.

[0055] Referring to FIG. 4, a soundproof tunnel (10) according to one embodiment of the present disclosure may include a lower membrane material (61).

[0056] The lower membrane (61) may be provided to accommodate vertical displacement of the roof truss beam (30). The lower membrane (61) may be provided with a flexible material installed at a constant height at the bottom of the intermediate partition (60) to have a height variable section. The lower membrane (61) may be made of a non-combustible membrane material.

[0057] The lower membrane (61) can perform spatial separation of the left and right driving lanes (1a, 1b) even if the central support (52) is forcibly slid through the slip hinge in response to the vertical displacement of the roof truss beam (30). Therefore, it can perform the function of blocking the propagation of flames to the other driving lane when a fire occurs in one driving lane.

[0058] The lower membrane material (61) may include a membrane material reinforcing member (62). The membrane material reinforcing member (62) may be provided as a curved or bent member that generates tension in the lower membrane material (61) to prevent vibration of the lower membrane material (61). The membrane material reinforcing member (62) can tighten the flexible lower membrane material (61) to prevent movement such as shaking, flapping, or trembling of the lower membrane material (61) due to wind pressure in the driving lane.

[0059] The soundproof tunnel (10) may further include an upper membrane material (63).

[0060] The upper membrane (63) may be provided to accommodate vertical displacement of the roof truss beam (30). The upper membrane (63) may be provided with a flexible material installed at a constant height on the top of the intermediate partition (60) to have a height variable section. The upper membrane (63) may be made of a non-combustible membrane material.

[0061] The upper membrane (63) can perform spatial separation of the left and right driving lanes (1a, 1b) even if the central support (52) is forcibly slid through the slip hinge in response to the vertical displacement of the roof truss beam (30). Therefore, it can perform the function of blocking the propagation of flames to the other driving lane when a fire occurs in one driving lane.

[0062] The upper membrane material (63) may include a membrane material reinforcing member (64). The membrane material reinforcing member (64) may be provided as a curved or bent member that generates tension in the upper membrane material (63) to prevent vibration of the upper membrane material (63). The membrane material reinforcing member (64) can tighten the flexible upper membrane material (63) to prevent movement such as shaking, flapping, or trembling of the upper membrane material (63) due to wind pressure in the driving lane.

[0063] FIG. 8 is an enlarged cross-sectional view of lines AA and BB of FIG. 1, and FIG. 9 and FIG. 10 are installation state diagrams of a resistance-reducing wing according to one embodiment of the present disclosure.

[0064] Referring to FIGS. 1, 8 to 10, an exhaust fan (11) may be installed on the upper part of the left and right driving lanes (1a, 1b) inside the soundproof tunnel (10). The exhaust fan (11) may be supported and installed on a roof truss beam (30) or a separate structure.

[0065] Multiple exhaust fans (11) may be installed in the driving lanes according to the length of the soundproof tunnel (10). The exhaust fans (11) installed in the left and right driving lanes (1a, 1b) may have different exhaust directions.

[0066] A resistance-reducing wing (70) may be installed on the roof truss beam (30) to reduce air resistance of the airflow generated by the exhaust fan (11) and to accelerate the airflow (exhaust flow).

[0067] Resistance reduction wings (70) can be installed on the upper chord (31) and lower chord (32) respectively that constitute the roof truss beam (30).

[0068] The resistance-reducing wing (70) may be provided with a curved guide surface (71) that guides the airflow generated by the exhaust fan (11) toward the exhaust direction of the soundproof tunnel (10). The airflow flowing toward the exhaust direction through the upper chord (31) and lower chord (32) is facilitated by the Coanda effect, which causes the airflow to flow along the curved guide surface (71), thereby making it easier to form an airflow toward the exhaust direction.

[0069] The resistance-reducing wing (70) may be continuously extended along the longitudinal direction (L) of each of the upper chord (31) and lower chord (32) as shown in FIG. 9. Alternatively, as shown in FIG. 10, the resistance-reducing wing (70) may be installed spaced apart at a predetermined interval along the longitudinal direction (L) of each of the upper chord (31) and lower chord (32). That is, the resistance-reducing wing (70) may be installed intermittently along the longitudinal direction (L) of each of the upper chord (31) and lower chord (32).

[0070] The resistance-reducing wing (70) may be provided as a single member (70a) on each of the upper chord (31) and lower chord (32) as shown in FIG. 9(a), or as a pair (70b, 70c) provided on both sides of each of the upper chord (31) and lower chord (32) as shown in FIG. 9(b).

[0071] Through this, the exhaust flow inside the tunnel of the left and right driving lanes (1b) is accelerated without vortex phenomena, so that pollutants are quickly discharged, and thus the inside of the soundproof tunnel (10) can be kept pleasant.

[0072] FIG. 11 is an exemplary diagram showing a state in which a gap is formed in a roof truss beam according to one embodiment of the present disclosure, FIG. 12 is an enlarged view of the gap of FIG. 11, FIG. 13 is a perspective view of a filling member according to one embodiment of the present disclosure, and FIG. 14 is a side view of a filling member according to one embodiment of the present disclosure.

[0073] Referring to FIGS. 11 to 14, a filling member (80) that fills the gap between the connecting parts (35) can be installed in the connecting part (35) where an angle (α) is created between the segments (upper chord or lower chord) of the roof truss beam (30).

[0074] The filling member (80) may include a semicircular wedge-shaped plate (81) having an angle (α) and anti-detachment locking projections (82) that protrude from both sides of the wedge-shaped plate (81) to prevent the filling member (80) from falling out of the connecting part (35).

[0075] Through this, when a filling member (80) is inserted into the connection part (35) of the roof truss beam (30), the flanges between the segments of the roof truss beam (30) are in close contact with the filling member (80), thereby eliminating gaps, and the filling member (80) is prevented from detaching by the anti-detachment locking projection (82), making it easy to implement the welding joint of the filling member (80). As a result, the implementation of a curved soundproof tunnel (10) can be facilitated.

[0076] FIG. 15 is a cross-sectional view of a soundproof tunnel according to another embodiment of the present disclosure. In the following, components having the same function are given the same reference numerals, and detailed descriptions are omitted.

[0077] Referring to FIG. 15, a soundproof tunnel (10) according to one embodiment of the present disclosure may include a longitudinal smoke barrier wall (90).

[0078] The longitudinal smoke barrier (90) can be configured so that the intermediate partition (60) does not extend down to the central foundation concrete (50) but extends only a certain length from the roof covering (40). Accordingly, an evacuation opening (91) of a certain height (h) can be formed between the longitudinal smoke barrier (90) and the central foundation concrete (50).

[0079] The longitudinal smoke barrier (90) may include a steel plate or fabric material that does not require the driver's visibility and is not affected by vibrations caused by vehicle driving pressure.

[0080] The longitudinal smoke barrier (90) can extend about 1 to 3 m downward from the roof covering (40). This longitudinal smoke barrier (90) can connect the spaces of the left and right lanes through the evacuation opening (91) without completely separating the spaces of the left and right lanes of the soundproof tunnel (10).

[0081] Therefore, when a fire occurs inside the soundproof tunnel (10) and a situation arises where people need to evacuate to the opposite lane depending on the fire situation, rapid evacuation to the opposite lane is possible through the evacuation opening (91).

[0082] In addition, the longitudinal smoke barrier (90) can delay the spread of smoke and gas rising upwards in the event of a fire, and in a state where it cannot cross the lane, it can prevent casualties by first pushing out the upper air through the exhaust fan (11), which is a forced exhaust device.

[0083] Although the technical concept of the present invention has been explained above through specific embodiments, the scope of the present invention is not limited to these embodiments. Various embodiments that can be modified or varied by those skilled in the art within the scope that does not deviate from the gist of the technical concept of the present invention as specified in the claims shall also be considered to fall within the scope of the present invention.
