Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tunnel awning traffic safety, more particularly to a linear induction type awning for a highway tunnel curve. BACKGROUND

[0002] The external illumination of a highway tunnel is several ten thousand lux, and the internal illumination is several tens of lux. The difference between the internal and external illumination of the tunnel is huge, causing a black hole effect and visual shock to drivers. In order to alleviate the dramatic change of the light environment at the entrance of the tunnel, setting an awning at the entrance of the tunnel is a relatively effective method. The existing tunnel awnings mainly adopt a reinforced concrete type or a steel structure type. The reinforced concrete type awning has a relatively wide beam, which forms a horizontal shadow on the ground, causing a relatively obvious stroboscopic phenomenon and low visual comfort. The steel structure type awning generally sets a light-transmitting awning plate, and the top space is completely closed, which undoubtedly increases the length of the closed space and causes difficulty in air circulation.

[0003] The existing awning setting often ignores the fact that the awning itself is an obstacle, and there is a hidden danger of vehicles colliding with the awning, especially on a curved road section, where vehicles are more likely to collide with the awning. The existing awning also has the problems of improper light transition and discontinuous visual induction, causing the driver to experience two dark adaptation processes when entering the tunnel, the first being from the normal road section into the awning, and the second being from the awning into the tunnel. The two relatively large light environment changes undoubtedly reduce the comfort of the driver. The normal road sections inside and outside the highway tunnel are generally provided with lighting facilities, but the existing awning, as an extended section outside the tunnel, is generally not provided with lighting facilities, resulting in low brightness and low visual recognition effect of the awning at night, and an unreasonable brightness transition curve.

[0018] The highway tunnel curve linear induction sunshade of the present application has the following beneficial effects:

[0019] 1. The present application uses linear gradual change of the spatial range to alleviate the sudden black hole effect and closed tension during the process of entering the tunnel. The height of the height-gradual sunshade member at the top of the sunshade is gradually reduced from the starting point to the end point of the sunshade, and the height-gradual sunshade member at the top also expands outward to a certain extent. The visual space gradually changes from large to small, which not only realizes a reasonable transition in the degree of space from open outside the tunnel to closed inside the tunnel, but also alleviates the sharp transition of illumination brightness, thereby reducing the tension of the driver in the closed and dark environment of the tunnel.

[0020] 2. The present application uses hollow height staggered design to meet the needs of shading, smoke exhaust, and noise reduction. The light and shadow of the elliptical pavement enhances the visual line guiding effect. The height-gradual sunshade member at the top adopts a hollow height staggered design, and the side is provided with a ventilation hole. The sunshade function is realized, and the needs of ventilation, smoke exhaust, and noise reduction are also met. The hollow elliptical design forms an elliptical light and shadow on the pavement, which can enhance the visual line guiding effect. The spacing of the elliptical light and shadow is reasonable, which can help the driver to maintain a certain degree of vigilance and pay attention to the road environment in front, but without discomfort.

[0021] 3. The present application uses the middle line facilities (linear lighting, linear traffic column, and semicircular light belt), long line facilities (indicative waistline, hollow arrow, and induced large arrow), and ring facilities (arc-shaped reflective arch and ring contour belt) to construct a linear induction system, highlight the contour of the sunshade and the tunnel, enhance the visual line guiding effect, and clarify the road space right. The arrangement of the linear lighting and the semicircular light belt can highlight the overall contour of the sunshade at night, and also ensure that the sunshade has a relatively bright light environment at night.

[0022] 4. The combination of the hollow arrow of the sunshade, the induced large arrow inside the tunnel, and the linear traffic column and the indicative waistline enhances the continuity and consistency of the sunshade and the tunnel entrance induction.

[0023] 5. In the case of curved road sections, the height and width of the hollow arrows and large guiding arrows on the outer side of the curve are greater than those on the inner side of the curve, and the height of the linear traffic pillars on the outer side of the curve is also greater than that on the inner side. This strengthens the information guidance on the outer side of the curve and enhances the driver's avoidance effect on the outer sunshade, so as to prompt the driver to slow down and pay attention to maintaining the current lane.

[0032] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0033] like Figures 1-6 As shown, the linear guiding shading canopy for highway tunnel curves of the present invention includes multiple sections of shading canopy, which are interconnected and their height gradually decreases linearly. The shading canopy includes a support structure 1, a top shading system, a side shading system, a linear guiding system, and a guardrail 10, with the guardrail 10 located at the bottom of the support structure 1.

[0034] The support structure 1 comprises columns 11, arch ribs 12 and longitudinal beams 13, the columns 11 are vertically arranged on both sides, the arch ribs 12 are arranged in multiple and intervals on the top, and the longitudinal beams 13 are parallel to the highway and arranged on both sides; the top shading system comprises a first shading member 2 arranged on the top of the shading shed, a hollow staggered structure 21, a ventilation hole 22 and a hollow ellipse 23, the first shading member 2 is gradually reduced in height; the side shading system comprises a second shading member 3 arranged on the side of the shading shed and a hollow arrow 31; the linear induction system comprises a linear lighting lamp 4 arranged above the shading shed, an arc-shaped reflecting arch 14 and a semicircular light strip 15 arranged in the inner side of the column 11, an indicative waistband line 33 and an induction arrow 32 arranged on the side wall of the shading shed, a ring-shaped contour belt 5 arranged in the inner side of the tunnel, a linear traffic column 6 arranged in the inner side of the guardrail 10 and a combined lane indicator 7 arranged above the lane. The total length of the shading shed is 75-150 m, and the total length of the shading shed can be divided into 3-5 small sections according to the arrangement of the columns 11, and the length of each small section is 20-30 m, and then the arch ribs 12 are arranged to divide the shading shed into 15-25 sections.

[0035] The height of the first shading member 2 from the starting point to the ending point of the shading shed is linearly and gradually reduced, the top height at the starting point is 12-16 m, the top height at the ending point is consistent with the height of the tunnel, generally 6-8 m, the visual space is gradually changed from large to small, not only realizing the reasonable transition of the space degree from the outside of the hole to the inside of the hole, but also softening the sharp transition of the illumination brightness, which can reduce the nervousness of the driver to the closed and dark environment of the tunnel. The first shading member 2 can also extend outward by 2-5 m from the starting point of the shading shed, and the highest height can extend outward by 0.3-0.5 m from the starting point of the shading shed, which is beneficial to soften the sharp transition of the illumination at the starting point of the shading shed. The first shading member 2 adopts a hollow staggered structure 21, that is, the height of each section is linearly reduced from the starting point to the ending point of the section, forming a height stagger, and the staggered height of the hollow staggered structure 21 of each section is linearly and gradually reduced from the hole to the inside of the hole, not only effectively shielding direct sunlight, but also gradually reducing the sunlight irradiation range from the hole to the inside of the hole, and optimizing the brightness transition in the shading shed. The side of the hollow staggered structure 21 forms a ventilation hole 22, forming a lighting channel and a smoke exhaust channel, effectively meeting the needs of ventilation and smoke exhaust on the top of the shading shed.

[0036] The hollowed-out ellipse 23 is arranged directly above each lane, the length of the major axis is consistent with 2 / 5-3 / 5 of the length of each section of the light-shielding shed, that is, 20-30 m, and the length of the minor axis is 1 / 3-2 / 3 of the width of a single lane. The hollowed-out ellipse 23 is made of blue organic material, and small circular pores are arranged inside. The porosity of the hollowed-out ellipse 23 closer to the tunnel portal is smaller, and the light transmission is less. The light spot after light irradiation is projected on the center of the lane. The area of the first light-shielding component 2 at the top that is not hollowed out is made of dark gray organic material and covered with a transparent film. The light transmittance of the transparent film gradually changes according to the portal scotopic curve. With such a structural design, an elliptical light and shadow is formed on each lane, the visual guidance of the route is strengthened, the spacing of the elliptical light and shadow is reasonable, the driver's vigilance is promoted, and the driver pays attention to the road environment in front, but does not feel uncomfortable.

[0037] The indicative waistline 33 is arranged on the second light-shielding component 3 and the tunnel side wall, and is divided into two parts. The upper indicative waistline 33 is 3.0-3.5 m away from the ground, and the lower indicative waistline 33 is 1.5-2.5 m away from the ground. The width of a single indicative waistline 33 is 0.3-0.5 m. The paint is used to highlight the road alignment. The guide arrow 32 is arranged between the two indicative waistlines 33 of the tunnel side wall, and has a length of 4-6 m and a width of 1-1.5 m. Three to five guide arrows 32 are arranged between adjacent annular contour bands 5 to provide medium-density and medium-size visual information, which can meet the speed and direction of the driver.

[0038] The hollowed-out arrow 31 is arranged between the two indicative waistlines 33 of the second light-shielding component 3, and has a length of 4-6 m and a width of 1-1.5 m. Three to five hollowed-out arrows 31 are continuously arranged in each section of the light-shielding shed. The hollowed-out arrow 31 is made of organic material and is hollowed out by small circles. The porosity is consistent with the porosity of the top hollowed-out ellipse 23. The closer to the tunnel portal, the smaller the porosity and the less the light transmission. The area of the second light-shielding component 3 at the side that is not hollowed out is made of light gray organic material. With such a structural design, a part of sunlight can pass through the hollowed-out arrow 31 to irradiate the road surface, optimize the enclosed dark light environment of the light-shielding shed, and cooperate with the guide arrow 32 of the tunnel side wall to enhance the continuity and consistency of the guide of the light-shielding shed and the tunnel portal.

[0039] Linear lighting 4 is set from the starting point of the canopy top, the length is spread between the adjacent top hollowed-out ellipse 23, enhances the continuity of the top visual induction, and the linear lighting 4 can be dimmed, prompting the canopy road surface longitudinal light to be more uniform. Arc-shaped reflecting arch 14 and semicircular lamp strip 15 are set on the inner side of the stand column 11, wherein the arc-shaped reflecting arch 14 starts from the upper indicative waistline 33 and covers to the canopy top; the semicircular lamp strip 15 is located between the upper and lower indicative waistline 33, the structure section is semicircular, and the inside is provided with LED lamp strip 151. The arc-shaped reflecting arch 14 and the semicircular lamp strip 15 can outline the profile of the canopy, facilitate the driver to pay attention to the spatial line shape of the canopy, and reduce the collision probability. Ring profile strip 5 is set on the tunnel side wall, starts from the lower indicative waistline 33, covers to the hole top, and is set at an interval of 30-50 m, which can outline the profile of the tunnel.

[0040] Linear traffic column 6 is set on the road hard shoulder of the canopy and outside the tunnel boundary, the setting height is 0.9-1.2 m, the bottom color is red, the surface is provided with 2-3 layers of fluorescent yellow-green reflective film, and the ratio of the height of a single layer of reflective film to the diameter of the linear traffic column 6 is not less than 4. The setting interval of the linear traffic column 6 in the canopy area is 4-6 m, and the setting interval in the tunnel is 2-3 m. The starting point of the setting of the linear traffic column 6 is 3 s-5 s of travel before the canopy, and the end point is 3 s-5 s of travel after entering the tunnel. With such a structural design, the sharp change of visual reference information inside and outside the tunnel can be smoothed, and because the visual information inside the tunnel is much less than that outside the tunnel, the setting interval of the linear traffic column 6 inside the tunnel is smaller than that outside the tunnel.

[0041] Combined lane indicator 7 is located on the section of the frontmost stand column 11 and the last stand column 11 of the canopy, and has three signal display areas 71 and two content display areas 72. The signal display area 71 is set directly above the direction of the lane, if the current lane is allowed to pass, a green indication arrow is given, otherwise a red cross pattern is given. The content display area 72 is located between the two signal display areas 71, which can display information such as “pay attention to the front curve” and “pay attention to the front tunnel”, and remind the driver to pay attention to the front road information, so as to reduce the adverse effects of limited curve sight distance.

[0042] The height and width of the hollowed-out arrow 31 and the induction large arrow 32 when set on the outside of the curve are greater than the height and width when set on the inside of the curve, and the increase amplitude is 10%-20%. The height of the linear traffic column 6 when set on the outside of the curve is greater than the height when set on the inside, and the increase amplitude is 10%-20%. With such a structural design, the information induction of the outside of the curve can be enhanced, the avoidance effect of the driver on the outside of the canopy can be enhanced, so as to prompt the driver to drive at a slow speed and pay attention to keep the current lane.

[0043] The embodiments of the present application are described above with reference to the accompanying drawings, but the present application is not limited to the above-described specific embodiments, and the above-described specific embodiments are merely illustrative, but not restrictive, and a person of ordinary skill in the art can make many forms under the inspiration of the present application without departing from the purpose of the present application and the scope protected by the claims, and these all belong to the protection of the present application.
