Description

Technical Field

[0001] This utility model belongs to the field of tunnel engineering design and construction technology, and in particular relates to a rainproof, breathable and light-shading shed for tunnel groups. Background Technology

[0002] With the continuous development of mountain road networks, the application of tunnel clusters is becoming increasingly common due to terrain and land use limitations. Insufficient spacing between tunnels can cause drivers to experience frequent changes in light and dark when entering and exiting tunnels, creating a "black and white hole effect," leading to visual fatigue and posing safety hazards. Currently, to address this issue, sunshades are often installed at tunnel entrances to achieve a smooth transition of light.

[0003] Existing shading canopy solutions have some shortcomings. For example, prior art document 1 (CN219826857U) discloses a tunnel arch frame for initial tunnel support, which focuses on adapting to uneven bedrock through adjustable support legs, addressing the stability of the support but not providing any shading function. Similarly, prior art document 2 (CN222414862U) discloses a photovoltaic power generation shading canopy for tunnels with adjustable brightness. It uses translucent photovoltaic glass to generate electricity and is equipped with batteries and an intelligent lighting system. While this solution achieves shading and energy saving, it is structurally complex and costly. Furthermore, its fully or semi-enclosed structure hinders natural ventilation between tunnels, potentially leading to the accumulation of pollutants such as vehicle exhaust within the tunnels, affecting air quality and driving safety. In addition, the maintenance cost of the photovoltaic system is also high. Therefore, there is an urgent need in the art for a tunnel group shading canopy that is simple in structure, moderately costly, and can effectively solve the problems of shading, rain protection, and ventilation simultaneously.

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings. Figures 1-9 The technical solutions of the embodiments of this utility model are clearly and completely described below. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0016] like Figures 1-9 As shown, the present invention provides a rainproof, breathable, and light-shading shed for tunnel groups, comprising two main parts: a load-bearing frame and a light-shading system.

[0017] The load-bearing frame consists of a concrete foundation 1, circumferential H-beams 2, and longitudinal H-beams 3. First, foundation trenches are excavated on both sides of the roadbed at the tunnel entrance, and concrete foundation 1 is poured to form a strip foundation. L-shaped pre-embedded reinforcing bars 202 are embedded in the concrete foundation 1, with threaded ends protruding from the top surface of the concrete foundation 1. Arch foot connecting steel plates 201 are installed at both ends of the circumferential H-beams 2. The arch foot connecting steel plates 201 are fixedly connected to the pre-embedded reinforcing bars 202 with nuts, thus fixing the two arch feet of the circumferential H-beams 2 to the concrete foundation 1, forming stable support. Multiple circumferential H-beams 2 are welded and fixedly connected to each other by longitudinal H-beams 3, forming the main load-bearing frame. The load-bearing frame also includes longitudinal steel frames 4 and circumferential steel frames 5 fixed to the circumferential I-beams 2. The longitudinal steel frames 4 are welded to the circumferential I-beams 2 at fixed intervals, and then the circumferential steel frames 5 are welded to the longitudinal steel frames 4 to form a secondary load-bearing grid for fixing the sunshade. After the load-bearing frame construction is completed, all steel components are ground to remove rust and coated with anti-rust paint.

[0018] The shading system of the sunshade canopy also includes a top shading plate 7 and side shading plates 6 fixed to the circumferential steel frame 5 via shading plate support components 8. The top shading plate 7 is an arc-shaped semi-transparent PC endurance board, and the side shading plates 6 are angled semi-transparent PC endurance boards. Their thickness is controlled at 5mm, their light transmittance is controlled between 10-30%, and their service life can reach 20 years. (See attached...) Figure 5 and 6 As shown, the side shading panels 6 include multiple long strips arranged along the direction of the shade canopy. These side shading panels 6 are staggered circumferentially along the circumferential steel frame 5, forming ventilation gaps 9 between adjacent side shading panels 6, serving as lateral ventilation holes. The lower edge of the upper side shading panel 6 covers the upper edge of the lower side shading panel 6, thus protecting the lower side shading panel 6 and effectively preventing rain and snow from entering the shade canopy through the ventilation gaps 9. No side shading panels 6 are installed at the arched base of the shade canopy to form arched base ventilation openings 10. This combination of "staggered gaps + arched base ventilation openings" constitutes an effective natural ventilation channel and effectively reduces the amount of rainwater entering the shade canopy during rainy or snowy weather.

[0019] This utility model achieves the shading function of the tunnel entrance through the top and side shading panels, effectively reducing the visual load on the driver; the staggered gaps of the side shading panels and the arch foot ventilation openings form an effective air circulation channel, significantly improving the ventilation performance of the tunnel group and improving the air quality inside the tunnel; the overall structure also has a rainproof function, solving the problem of dry and wet transition of the road surface at the tunnel entrance in rainy and snowy weather.

[0020] In a preferred embodiment, such as Figures 3-4 As shown, both the longitudinal steel frame 4 and the circumferential steel frame 5 are stainless steel hollow rectangular steel. The longitudinal steel frame 4 is welded to the circumferential I-beam 2, and the circumferential steel frame 5 is welded to the longitudinal steel frame 4. This structure can reduce the overall weight of the load-bearing frame while ensuring high structural strength.

[0021] In a preferred embodiment, such as Figure 7 As shown, the sunshade support assembly 8 includes a stainless steel connecting screw 801 and a fixing nut 802. Circular rubber gaskets 803 are provided at the contact points between the connecting screw 801 and the fixing nut 802 and the circumferential steel frame 5 and the sunshade. These gaskets, installed on the contact surfaces of the connecting screw, nut, steel frame, and sunshade, serve to seal and waterproof the surface. A conical rubber cap 804 is connected to the upper end of the connecting screw 801. The lower part of the conical rubber cap 804 has a threaded hole that connects to the connecting screw 801. Its upper surface is adhered to the sunshade with adhesive. This effectively prevents the sunshade from swaying or falling off under wind load, enhancing its wind resistance.

[0022] like Figure 9 As shown, the sunshade of this utility model is installed at the tunnel entrance and fixedly connected to the tunnel portal wall, with the joint treated with waterproof membrane. This sunshade uses a purely physical structure, requiring no electrical system, resulting in a simpler structure, significantly reduced manufacturing and maintenance costs, and higher reliability. It features a simple and aesthetically pleasing structure, high durability, and quick and convenient assembly. The sunshade uses a stainless steel frame and weather-resistant PC endurance board, making the overall structure corrosion-resistant and long-lasting. The main structure of the sunshade uses a combination of bolted and welded connections, allowing for quick assembly and high construction efficiency. Through this structure, multiple functions of shading, rain protection, and ventilation are cleverly achieved using simple physical construction, making it particularly suitable for tunnel projects with high ventilation requirements and a focus on cost-effectiveness.

[0023] The above are preferred embodiments of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
