Description

Technical Field

[0001] The present invention relates to an energy-saving luminous sign in the field of tunnel safety induction and lighting, in particular to a multi-functional tunnel contour belt structure and construction method. Background Art

[0002] The national transportation industry standard specifications have regulations on the lighting settings of highway tunnels. For example, Article 3.0.2 of the "Code for Lighting Design of Highway Tunnels (JTG / T D70 / 2 - 01 - 2014)" stipulates that the lighting setting conditions for highway tunnels at all levels shall meet the following requirements: ① Expressway and first-class highway tunnels with a length L > 200m shall be provided with lighting; ② Expressway optical long tunnels and first-class highway optical long tunnels with a length of 100m < L ≤ 200m shall be provided with lighting; ③ Second-class highway tunnels with a length L > 1000m shall be provided with lighting; second-class highway tunnels with a length of 500m < L ≤ 1000m shall be preferably provided with lighting; for third-class and fourth-class highway tunnels, it shall be determined according to the actual situation; ④ For tunnels with pedestrian requirements, lighting facilities that meet the pedestrian passage requirements shall be provided according to the tunnel length and environmental conditions; ⑤ For tunnels without lighting, sight guidance facilities shall be provided. And Article 9.3.5 stipulates that for expressway and first-class highway tunnels with a length L ≤ 500m equipped with self-luminous induction facilities and directional reflective contour markers, all lamps can be turned off at night. For second-class highway tunnels with a length L ≤ 1000m equipped with directional reflective contour markers, all lamps can be turned off at night. When the highway has lighting, the night lighting brightness on the tunnel section shall be consistent with the road brightness level; when the highway has no lighting, the night lighting brightness of expressway and first-class highway tunnels can be taken as 1.0 cd / ㎡, and the night lighting brightness of second-class highway tunnels can be taken as 0.5 cd / ㎡. When the night traffic volume of a one-way traffic tunnel is not greater than 350 veh / (h·ln) and that of a two-way traffic tunnel is not greater than 180 veh / (h·ln), only emergency lighting lamps can be turned on.

[0003] It is evident that the aforementioned standards and specifications do not mandate lighting facilities for short and medium-sized tunnels. Most tunnels on Class II, III, and IV highways are not required to have lighting facilities. For tunnels without lighting, the specifications stipulate self-illuminating guidance facilities and directional reflective delineators. The national transportation industry standard and specification "JTG D81-2017 Highway Traffic Safety Facilities Design Specification" allows the use of tunnel delineators as guidance facilities to enhance the tunnel's guidance effect, but it does not specify the specific form of the tunnel delineator. Current applications generally involve directly adding a plate-shaped delineator to the tunnel and applying reflective film, using vehicle headlights for retroreflection to improve the tunnel's reflective and guidance lighting capabilities. However, simply installing delineators with only reflective functions, without lights, poses significant safety hazards for vehicles and pedestrians. In current practical applications, tunnel delineators offer limited functionality. Many tunnels experience high traffic volume and significant traffic safety pressures, and the demand for tunnel guidance lighting from residents along the route is high. However, simply adding conventional electric lights to tunnel lighting equipment is prohibitively expensive for construction and subsequent electricity management, highlighting the conflict between energy conservation and traffic safety.

[0004] Currently, some attempts are being made to improve the reflectivity and guidance lighting capabilities of tunnels using tunnel outlines. For example, Chinese patent CN 106168357 A discloses a tunnel lighting warning system that uses V-shaped reflectors to reflect vehicle headlights while simultaneously incorporating a light-emitting device to enhance brightness within the tunnel. However, because the LED lights in this device are encased inside a housing with an energy-storing light-emitting layer coated on the outer surface, the lighting effect is poor. Another Chinese patent, CN209431334U, discloses a W-shaped reflector ring with a light source installed in the lower center. Because the light source is deeply embedded within the reflectors on both sides, the area illuminated on the road surface is limited, it lacks emergency lighting functionality, and this type of outline is bulky, complex in construction, and economically inefficient. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a multifunctional tunnel contour strip structure and construction method that is simple and beautiful in structure, safe and reliable, durable, non-glare, energy-saving and emission-reducing.

[0006] The technical solution adopted for the purpose of this invention is achieved by the following method: a multifunctional tunnel contour strip structure, wherein the contour strip is assembled and installed in the tunnel by contour strip marking components, the contour strip marking components include a bracket and a shell with a parabolic cylindrical shape, wherein the outer surface of the shell is the marking object of the contour strip marking components, and the shell is connected to the bracket.

[0007] In the aforementioned multifunctional tunnel contour strip structure, the bracket is cross-shaped, and two or more brackets are provided in the contour strip marking component; preferably, the bracket is molded from thermoplastic resin PA66 or other resins as the main raw material, with the addition of other additives; in use, the bracket on the contour strip marking component is fixed to the tunnel wall by connectors, preferably bolts.

[0008] In the aforementioned multifunctional tunnel contour strip structure, the shell is a thin shell.

[0009] In the aforementioned multifunctional tunnel contour strip structure, the marker of the contour strip marking component is a reflective material, and the contour strip marking component with a reflective marker is a reflective contour strip marking component, which has retroreflective function.

[0010] In the aforementioned multifunctional tunnel contour strip structure, the reflective element of the reflective contour strip marking component is made of retroreflective material. Preferably, the retroreflective material includes reflective materials such as glass beads, microprisms, and reflective lattices. The reflective element is made using synthetic resin technology, thin film technology, coating technology, and micro-replication technology. The color of the reflective element includes white, yellow, red, green, blue, brown, orange, fluorescent yellow, fluorescent orange, and fluorescent yellow-green. The reflective element has self-cleaning and anti-aging properties. The color and retroreflection level of the reflective element are selected according to factors such as the size of the tunnel and traffic flow.

[0011] In the aforementioned multifunctional tunnel contour strip structure, a protective film is provided on the surface of the reflective element of the reflective contour strip marking member. The protective film is made of transparent plastic with flame-retardant properties; preferably, the protective film is made of PETG plastic.

[0012] In the aforementioned multifunctional tunnel contour strip structure, a groove is provided at the top of the parabolic cylindrical surface of the shell of the reflective contour strip marking member, and a light array is provided in the groove. The reflective contour strip marking member with the light array is an illuminated reflective contour strip marking member, which has both retroreflective and illumination functions. Preferably, the groove at the top of the parabolic cylindrical surface of the shell is inverted V-shaped, and the light array is composed of several LED lights arranged and combined.

[0013] In the aforementioned multifunctional tunnel contour strip structure, the marker of the contour strip marking component is a self-luminous body, and the contour strip marking component with a self-luminous body is a self-luminous contour strip marking component, which has a self-luminous function.

[0014] In the aforementioned multifunctional tunnel contour strip structure, the self-luminous body of the self-luminous contour strip marker component is made of a long afterglow material, which has strong self-luminous performance under light excitation and plays an emergency luminous induction role in the event of a sudden power outage and loss of lighting in the tunnel.

[0015] In the aforementioned multifunctional tunnel contour strip structure, the markers of the contour strip marking component are self-luminous and reflective, wherein the self-luminous and reflective are arranged alternately, and the contour strip marking component with self-luminous and reflective markers is a self-luminous and reflective contour strip marking component, which has the dual functions of self-luminescence and retroreflection.

[0016] In the aforementioned multifunctional tunnel contour strip structure, a groove is provided at the top of the parabolic cylindrical surface of the shell of the self-luminous reflective contour strip marking component, and a light array is provided in the groove. The self-luminous reflective contour strip marking component with the light array is a self-luminous illuminated reflective contour strip marking component. The self-luminous illuminated reflective contour strip marking component has three functions: retroreflection, illumination, and emergency light induction in the event of a sudden power outage or when the tunnel is an unlit tunnel. Preferably, the groove at the top of the parabolic cylindrical surface of the shell is inverted V-shaped, and the light array is composed of several LED lights arranged and combined.

[0017] In the aforementioned multifunctional tunnel contour strip structure, the outer surface of the parabolic cylindrical shell with self-luminous bodies is made of transparent material. Preferably, the shell is made of transparent plastic with flame-retardant properties. Inside the parabolic cylindrical shell made of transparent material, there is a light array, which is composed of several LED lights arranged and combined.

[0018] When setting contour strips in tunnels according to the present invention, the contour strips are composed of one or more of the following: reflective contour strip marking components, illuminated reflective contour strip marking components, self-illuminating contour strip marking components, self-illuminating reflective contour strip marking components, and self-illuminating and illuminated reflective contour strip marking components. Preferably, the contour strips are composed of one or more of the following: reflective contour strip marking components, illuminated reflective contour strip marking components, and self-illuminating and illuminated reflective contour strip marking components. The contour strips formed by a single combination of reflective contour strip marking components are considered reflective contour strips, while the contour strips formed by a combination of reflective contour strip marking components and self-illuminating and illuminated reflective contour strip marking components are considered reflective contour strips. The outline is constructed as a reflective and self-illuminating lighting contour strip, which is formed by combining illuminated reflective outline strip marker components and self-illuminating reflective outline strip marker components. The contour strips composed of different combinations are connected according to the transverse outline shape of the tunnel to form a ring tunnel outline strip. Each tunnel is equipped with multiple ring tunnel outline strips of the same or different combinations. The spacing between each tunnel outline strip can be the same or different, so as to achieve the purpose of multi-functional guidance, lighting and emergency luminous escape guidance of the tunnel outline strip. The tunnel includes walls and road surface. Preferably, the tunnel walls are secondary lining walls.

[0019] In practical applications, multiple contour strips with the same or different spacings are set on the inner wall of the tunnel. Within a certain longitudinal section of the tunnel, the spacing between these contour strips is the same. If a combination of multiple illuminated reflective contour strip markers and self-illuminating reflective contour strip markers is arranged, the number of self-illuminating reflective contour strip markers is generally even, symmetrical about the central axis of the tunnel cross-section. Besides providing illumination under normal conditions, these self-illuminating reflective contour strip markers also serve as emergency light-guiding elements in the event of a sudden power outage or when the tunnel is unlit. The luminous flux of all n+n1 lamps in the combined illuminated and self-illuminating reflective contour strip marker array is the same, F. The angle between the i-th lamp and the edge of the longitudinal illumination area of ​​the tunnel is 2β. i The included angle along the edge of the transverse irradiation zone of the tunnel is 2δ. i The average brightness at any point on the road surface is required to be no less than the average brightness required by the design [L].

Detailed Implementation

[0084] The present invention will be further described in detail below with reference to the embodiments shown in the accompanying drawings:

[0085] Example 1

[0086] See attached document Figure 1 and attached Figure 4 A reflective contour strip 10 is formed by a single combination of reflective contour strip marking components 4. The reflective contour strip marking component 4 includes a bracket 1 and a shell 2 with a parabolic cylindrical shape. The outer surface of the shell 2 is a reflector 3, and a protective film is provided on the surface of the reflector 3. The reflector 3 has retroreflective function.

[0088] The reflective contour strip marking component 4 has a length of 55cm to 65cm, an upper width of 9cm to 11cm, and a height of 16cm to 18cm.

[0089] The reflective contour strip 10, composed of multiple reflective contour strip marker components 4, is applied to tunnels with relatively complete lighting and guidance facilities but still requiring improvement. Connected according to the tunnel's transverse contour shape, it forms a ring-shaped tunnel contour strip, serving a retroreflective function to enhance the tunnel's lighting and guidance effects. Each tunnel is equipped with multiple identical, single-combination reflective ring-shaped tunnel contour strips. The spacing between each tunnel contour strip can be the same or different, achieving the purpose of lighting and guidance through the tunnel contour strip.

[0090] Example 2

[0091] See attached document Figure 1 Appendix Figure 3 and attached Figure 5 A reflective self-illuminating contour strip 12, composed of a reflective contour strip marking component 4 and a self-illuminating reflective contour strip marking component 9, is installed on the wall 11a of a tunnel 11. The reflective contour strip marking component 4 includes a bracket 1 and a shell 2 in the shape of a parabolic cylinder. The outer surface of the shell 2 is a reflector 3, and a protective film is provided on the surface of the reflector 3. The reflector 3 has retroreflective function. The self-illuminating reflective contour strip marking component 9 includes a bracket 1 and a shell 2 in the shape of a parabolic cylinder. The outer surface of the shell 2 is composed of a self-illuminating body 8 and a reflector 3, wherein the self-illuminating body 8 and the reflector 3 are arranged alternately. A protective film is provided on the surface of the reflector 3. An inverted V-shaped groove 5 is provided at the top of the parabolic cylinder of the shell 2. A lamp array 6 is provided in the groove 5, which has the functions of retroreflection and illumination, as well as emergency light-guiding function in the event of a sudden power outage in the tunnel or in the case of an unlit tunnel.

[0092] The length of the reflective contour strip marking component 4 is 55cm to 65cm, the upper width is 9cm to 11cm, and the height is 16cm to 18cm; the length of the self-illuminating reflective contour strip marking component 9 is 18cm to 22cm, the upper width is 9cm to 11cm, and the height is 16cm to 18cm, and the degree of the lower inverted V-shaped included angle 2α1 is determined by the spacing between the multiple contour strips;

[0093] The reflective contour strip marking component 4 and the self-illuminating reflective contour strip marking component 9 are combined to form a ring-shaped reflective self-illuminating contour strip 12, which is connected according to the transverse contour shape of the tunnel. The number of self-illuminating reflective contour strip marking components 9 is generally even, symmetrical about the central axis of the tunnel cross section. It is used in tunnels with relatively complete lighting facilities and lack of guidance facilities, and has dual functions of lighting and emergency guidance. It plays an emergency luminous guidance role in the case of sudden power failure and loss of lighting in the tunnel or in the case of an unlit tunnel. According to the actual needs of tunnel lighting and guidance, a ring-shaped reflective self-illuminating contour strip 12 is set with the same or different combinations of multiple reflective contour strip marking components 4 and multiple self-illuminating reflective contour strip marking components 9. Each tunnel is equipped with multiple ring-shaped reflective self-illuminating contour strips 12 with the same or different combinations. The spacing of each reflective self-illuminating contour strip 12 can be the same or different, so as to achieve the purpose of multi-functional lighting and guidance of the tunnel contour strip.

The illuminated reflective contour strip marking component 7 includes a bracket 1 and a shell 2 with a parabolic cylindrical shape. The outer surface of the shell 2 is a reflector 3, and a protective film is provided on the surface of the reflector 3. An inverted V-shaped groove 5 is provided at the top of the parabolic cylindrical surface of the shell 2, and an array of lights 6 is arranged within the groove 5, providing retroreflection and... The self-luminous reflective contour marking component 9 includes a bracket 1 and a shell 2 with a parabolic cylindrical shape. The outer surface of the shell 2 is composed of a self-luminous body 8 and a reflective body 3, wherein the self-luminous body 8 and the reflective body 3 are arranged alternately. A protective film is provided on the surface of the reflective body 3. An inverted V-shaped groove 5 is provided at the top of the parabolic cylindrical surface of the shell 2. A lamp array 6 is provided in the groove 5, which has the functions of retroreflection and illumination, as well as emergency light-guiding function in the event of a sudden power outage in the tunnel or in the case of an unlit tunnel.

[0096] The length of the illuminated reflective outline marking component 7 is 55cm to 65cm, the upper width is 9cm to 11cm, and the height is 16cm to 18cm. The degree of the inverted V-shaped angle 2α at the bottom is determined by the spacing between the multiple outlines. The length of the self-illuminating reflective outline marking component 9 is 18cm to 22cm, the upper width is 9cm to 11cm, and the height is 16cm to 18cm. The degree of the inverted V-shaped angle 2α1 at the bottom is determined by the spacing between the multiple outlines.

[0097] The aforementioned arrangement of multiple illuminated reflective self-luminous contour strips 13 with identical or different spacings on the tunnel wall ensures that the spacing l of these strips is the same within a certain longitudinal section of the tunnel. Without loss of generality, it is assumed that the illuminated reflective self-luminous contour strips 13 serve both illumination and emergency guidance functions, i.e., a combination of multiple illuminated reflective contour strip marker components 7 and multiple self-luminous illuminated reflective contour strip marker components 9. The number of self-luminous illuminated reflective contour strip marker components 9 is generally even, symmetrical about the central axis of the tunnel cross-section. Besides their normal illumination function, these components 9 also provide emergency illumination guidance in the event of a sudden power outage or when the tunnel is unlit. The luminous flux of all n+n1 lamps in the combined array of illuminated reflective contour strip marker components 7 and self-luminous illuminated reflective contour strip marker components 9 is the same, F. The angle between the i-th lamp and the edge of the longitudinal illumination area of ​​the tunnel is 2β. i The included angle along the edge of the transverse irradiation zone of the tunnel is 2δ. iThe average brightness at any point on the road surface is required to be no less than the average brightness required by the design [L].
