Description

Technical Field

[0001] The utility model relates to the technical field of tunnel engineering, in particular to a sunshade shed used in highway tunnels. Background Art

[0002] When a car enters or exits a tunnel, due to the large difference in brightness between inside and outside the tunnel, a "black hole effect" and a "white hole effect" will occur when entering or exiting the tunnel. It is difficult for the driver to adapt to the changes in light intensity, and there will be obvious visual differences, accompanied by short-term "blindness", making it impossible to judge the traffic conditions near the tunnel entrance, affecting driving comfort, and in serious cases, safety accidents may occur.

[0003] On the other hand, with the development of domestic tunnel engineering, the number of continuous highway tunnel groups is increasing. Generally speaking, considering multiple factors such as lighting, ventilation and driving safety, adjacent tunnels with a tunnel spacing S≤250m are classified as adjacent tunnels. When passing through adjacent tunnels, drivers will experience the double visual impact of alternating light and dark changes brought by the "white hole" and "black hole" effects when driving on a clear day, that is, the "dark-bright-dark" process. Compared with a single tunnel, its safety hazards are greater and the risks are higher. Therefore, it is of great significance to study how to take effective measures to reduce the impact of light changes on the driver's vision at the junction of bridges and tunnels in extra-long highway tunnel groups to improve driving safety.

[0004] At present, the common practice in my country to improve the conditions of "dark-bright-dark" during sunny days, "bright-dark-bright" at night, and "dry-humid-dry" on rainy (snowy) days in tunnels adjacent to highways is to set up tunnel entrances to enhance lighting and light-reducing structures. Although there are a small number of awnings between tunnels adjacent to highways in the engineering community, their design is mainly determined by experience. There is little theoretical research on the light environment design and ventilation requirements of awnings between tunnels, and the shading and ventilation and smoke exhaust effects are not good.

[0005] In summary, there is an urgent need for a sunshade shed for highway tunnels to solve the problems existing in the prior art. Utility Model Content

[0031] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below, and preferred embodiments of the present invention are given. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0033] Example:

[0034] See also Figure 1-Figure 4 This embodiment provides a sunshade shed for a highway tunnel, comprising:

[0035] A light shielding segment 7, wherein a plurality of light shielding segments 7 are arranged between two adjacent tunnels along the longitudinal direction;

[0036] At least one smoke exhaust light shielding section 8, wherein the smoke exhaust light shielding section 8 is arranged between two adjacent light shielding sections 7;

[0037] The ceiling of the smoke exhaust shading section 8 is higher than the ceiling of the shading section 7, and the ceilings of the shading section 7 at both ends of the smoke exhaust shading section 8 extend to the interior of the smoke exhaust shading section 8; the ceiling of the smoke exhaust shading section 8 is inclined, that is, the first end of the ceiling of the smoke exhaust shading section 8 is lower than the second end of its ceiling (more strictly speaking: the height distance between the first end of the ceiling of the smoke exhaust shading section 8 and the road surface is smaller than the height distance between the second end of the ceiling and the road surface), a vent one is formed between the first end of the ceiling of the smoke exhaust shading section 8 and the ceiling of the shading section 7 below it, and a vent two is formed between the second end of the ceiling of the smoke exhaust shading section 8 and the ceiling of the shading section 7 below it, and the flow cross-section of the vent one is smaller than the flow cross-section of the vent two, which is conducive to ventilation inside the tunnel (i.e., exhausting the smoke inside the tunnel).

[0038] Specifically, the ceiling of the light-shielding section 1 7 is arranged parallel to the road surface, that is, the height distance between the first end of the ceiling of the light-shielding section 1 7 and the road surface is equal to the height distance between the second end of the ceiling and the road surface. When the light-shielding section in this embodiment is installed, the ventilation opening 1 and the ventilation opening 2 are arranged in sequence along the direction of the traffic flow between the tunnels, that is, the flow cross-section of the smoke exhaust light-shielding section 8 gradually increases along the direction of the traffic flow (that is, the height distance between the ceiling of the smoke exhaust light-shielding section and the road surface gradually increases from the first end to the second end), which is conducive to the air flow inside the tunnel flowing with the traffic flow, and facilitates ventilation inside the tunnel. At the same time, the light-shielding sections 1 at both ends extend to the interior of the smoke exhaust light-shielding section 8, preventing rainwater and strong light from entering the interior of the light-shielding section through the gap between the light-shielding section 1 and the smoke exhaust light-shielding section, thereby playing the role of shielding rain and strong light.

[0039] Preferably, see Figure 1-Figure 2 The shading section 7 includes a supporting frame 1 and a shading plate 6. The supporting frame 1 includes an arc-shaped cross beam 4 and a longitudinal beam 5. A plurality of the arc-shaped cross beams 4 are arranged at intervals along the longitudinal direction and adjacent arc-shaped cross beams 4 are connected by a plurality of longitudinal beams 5, thereby forming the supporting frame 1; the shading plate 6 is arranged on the upper part of the supporting frame 1.

[0040] See also Figure 1-Figure 4 The smoke exhaust shading section 8 includes a supporting frame 2 and a shading plate 2 18. The supporting frame 2 includes an arc-shaped cross beam 2 16 and a longitudinal beam 2 17. A plurality of the arc-shaped cross beams 2 16 are arranged at intervals along the longitudinal direction and the height of each arc-shaped cross beam 2 16 gradually increases along the longitudinal direction. Two adjacent arc-shaped cross beams 2 16 are connected by a plurality of longitudinal beams 2 17; the shading plate 2 18 is arranged on the upper part of the supporting frame 2.

[0041] Preferably, the arc-shaped cross beam 1 4 and the arc-shaped cross beam 2 16 both include a vertical beam and an arc-shaped beam, and the two ends of the arc-shaped cross beam are respectively connected to the vertical beam, so that the manufacturing difficulty of the arc-shaped cross beam 1 and the arc-shaped cross beam 2 can be reduced. Figure 3 , Figure 4 As shown, the second arc-shaped cross beam 16 includes a second vertical beam 16.1 and a second arc-shaped beam 16.2, and both ends of the second arc-shaped beam 16.2 are respectively connected to the second vertical beam 16.1, thereby forming an arch structure.

[0042] Please continue to see Figure 3 and Figure 4, the support frame 2 also includes a support beam 11 and a support beam 12 (that is, arranged on the arc-shaped beam 16.2) arranged on the top of the arc-shaped cross beam 16, the first ends of the support beam 11 and the support beam 12 are connected to the arc-shaped cross beam 16, and the second end of the support beam 11 is connected to the beam body of the support beam 12; further, the shading plate 2 18 is provided on the side of the support frame 2 close to the support beam 12, the side of the support frame 2 close to the support beam 11, and each support beam 12 along the longitudinal direction, and a wire mesh 10 is provided on each support beam 11 along the longitudinal direction; further, from the vent 1 to the vent 2, the length L of each support beam 11 gradually increases, and the angle α between each support beam 12 and the horizontal plane also gradually increases. That is, a triangular prism with a gradually increasing longitudinal flow cross-section is provided on the ceiling of the smoke exhaust shading section, and both ends and one side (i.e., the side where the wire mesh is provided) of the triangular prism are unclosed structures, thereby forming a smoke exhaust port on the ceiling of the smoke exhaust shading section, further improving the ventilation effect of the shading shed. Furthermore, the second end of the support beam 1 is connected to the beam body of the support beam 2, and the shading plate 2 on the support beam 2 can cover the wire mesh to prevent rainwater from entering the shading shed from the wire mesh as much as possible.

[0043] Preferably, the shading plate 1 and the shading plate 2 may be arranged in different ways in different embodiments. Taking the shading plate 1 6 as an example, the shading plate 1 6 may be one or more large plates covering the supporting frame 1, or may be arranged in multiple sections along the longitudinal direction, and a single section of the shading plate 1 6 is arranged between two adjacent arc-shaped cross beams 1 4.

[0044] Preferably, see Figure 1 and Figure 2 , the light shielding section 17 at the outer end is connected to the tunnel portal 1 through the anchoring assembly 12. Furthermore, an end shed 3 is provided between the light shielding section 17 at the outer end and the tunnel portal 1. The end shed is mainly used to cover the gap between the tunnel portal and the light shielding section 1 to ensure the effect of shading and rainproofing; the end shed can be determined whether to be set according to the actual situation. Generally, when the tunnel portal is a bamboo-cutting-type portal, the end shed can be set, which can reduce the difficulty of matching and installing the light shielding section 1 at the outer end and the tunnel portal and the difficulty of manufacturing the light shielding section 1 at the outer end.

[0045] See also Figure 2 At least one of the light shielding section 7 and the smoke exhaust light shielding section 8 is provided with a communication port 9 on the side. The communication port 9 is used to facilitate the entry and exit of vehicles and the transfer of personnel from the communication port when an accident occurs inside the tunnel.

[0046] Preferably, the shading section 1 7 and the smoke shading section 8 are connected to the crash pier 13 on the road through the anchor assembly 2 15. The crash pier is used to provide basic support for the shading shed structure; when the shading shed in this embodiment is used for a bridge between tunnels, the shading section 1 7 and the smoke shading section 8 are connected to the crash pier 13 through the anchor assembly 2 15, and the crash pier 13 is set on the lower bridge 14; when the shading shed in this embodiment is used for a highway between tunnels, the shading section 1 7 and the smoke shading section 8 are also connected to the crash pier 13 through the anchor assembly 2 15, and the crash pier is set on the highway pavement.

[0047] In some embodiments, at the overlapping part of the shading section 1 and the smoke exhaust shading section, the two may share a supporting frame, that is, arc beam 1 and arc beam 2 are respectively arranged at different heights between two parallel vertical beams, so as to achieve the effect of sharing a supporting frame; of course, it is also feasible that the shading section 1 and the smoke exhaust shading section are supported by supporting frames respectively. The specific arrangement can be adjusted and designed by personnel in this field according to the actual installation environment.

[0048] Preferably, the sunshade plate 1 and the sunshade plate 2 in this embodiment both adopt 840 aluminum-magnesium-manganese alloy roof panels.

[0049] Preferably, in order to increase the smoke exhaust effect of the sunshade, the sunshade segment 1 and the smoke exhaust sunshade segment can be alternately arranged to ensure that the two outer ends are sunshade segments 1. Of course, those skilled in the art can also consider the arrangement of including more than two sunshade segments 1 between the two smoke exhaust sunshade segments according to actual conditions.

[0050] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
