Description

Technical Field

[0001] The present application belongs to the field of road structure design, and specifically relates to a ventilation shed and tunnel group. Background Art

[0002] With the rapid development of my country's economy, highway construction has entered a period of vigorous development. Tunnels are widely used in highway construction because of their advantages of overcoming height differences, shortening mileage, improving linear standards, saving land and protecting the environment.

[0003] In some areas with complex terrain, there are dense clusters of tunnels. The distance between the entrances of two adjacent tunnels is usually short. The tunnels are tubular structures with dim light inside. When drivers exit the tunnel or enter the tunnel from the outside, they will feel a sharp change in brightness inside and outside the tunnel, causing visual discomfort to the driver.

[0004] In the related art, a tunnel shed is set between two tunnels to alleviate the brightness difference between inside and outside the tunnel, so that the driver can have a smooth visual adaptation process to the brightness change. However, the tunnel shed currently used only has a single shading function and cannot effectively achieve ventilation. Exhaust gas and other pollutants generated during vehicle driving will flow from the upstream tunnel to the downstream tunnel along with the airflow of the vehicle, causing polluted gases to flow between the upstream and downstream tunnels, affecting the driver's driving comfort and safety. Utility Model Content

[0005] The present application provides a ventilation shed hole to solve at least one technical problem existing in the background technology, which can realize air circulation inside and outside the shed hole, promote air replacement, and improve the driving safety and comfort of the driver.

[0006] A second aspect of the present application provides a tunnel group.

[0007] The technical solution adopted in this application is:

[0008] The first embodiment of the present application provides a ventilation shed tunnel connected to an upstream tunnel and a downstream tunnel, comprising:

[0009] A first shed tunnel section is connected to the upstream tunnel, and a vent is formed on the first shed tunnel section;

[0010] The second tunnel section is connected to the downstream tunnel, and a fresh air inlet is formed on the second tunnel section.

[0011] According to the ventilation tunnel provided by the first aspect embodiment of the present application, the tunnel is divided into a first tunnel section and a second tunnel section, which are respectively connected to the upstream tunnel and the downstream tunnel. Based on this structure, the airflow can be managed independently in the first tunnel section and the second tunnel section, which helps to more effectively control the cross-flow and diffusion of gaseous pollutants. The dirty airflow in the first tunnel section can be discharged outward through the ventilation port. When the traffic passes through the traffic entrance of the first tunnel section from the upstream tunnel, the dirty flowing air generated by the traffic in the upstream tunnel continues to flow inside the first tunnel section. Driven by the traffic, the dirty flowing air in the first tunnel section will rush out rapidly from the ventilation port, accelerating the outflow of the dirty gas in the first tunnel section, replacing the air in the first tunnel section and even the entire tunnel, thereby improving the air quality in the first tunnel section. Since the airflow is accelerated to flow outward in the first tunnel section, when the traffic enters the second tunnel section, a negative pressure is formed in the second tunnel section, and the external air can enter the second tunnel section through the fresh air inlet, thereby realizing the introduction of fresh air in the second tunnel section and increasing the proportion of fresh air in the entire tunnel. As the traffic continues to enter the downstream tunnel, fresh air can enter the downstream tunnel, thereby realizing air renewal in the downstream tunnel. It not only realizes ventilation, but also retains the original shading function of the shed tunnel, ensuring that the driver can smoothly adapt to the brightness changes when passing through the shed tunnel, reducing visual discomfort, and improving the air quality between tunnels, realizing functional integration and optimization. In summary, the ventilation shed tunnel provided in the embodiment of the present application can realize air circulation inside and outside the shed tunnel, promote air replacement, and improve the driving safety and comfort of the driver.

[0016] According to one embodiment of the present application, the angle between the extension direction of the guide plate and the horizontal plane ranges from 30° to 60°.

[0017] According to one embodiment of the present application, in the first shed tunnel section, the minimum vertical spacing between the upper and lower layers of the sunshade panels is 1.5 meters, and the maximum vertical spacing is 3.5 meters.

[0018] According to one embodiment of the present application, in the first shed hole section, the shading plate of the upper layer is an inverted V-shaped integrated structure, and the shading plate of the lower layer is an inverted V-shaped split structure;

[0019] The projection area of ​​the upper shading plate covers at least a part of the area of ​​the lower shading plate.

Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0042] like Figures 1 to 3 As shown, the first embodiment of the present application provides a ventilation tunnel 1, which is connected to the upstream tunnel 21 and the downstream tunnel 22, including: a first tunnel section 11, which is connected to the upstream tunnel 21, and a vent 111 is formed on the first tunnel section 11; a second tunnel section 12, which is connected to the downstream tunnel 22, and a fresh air inlet 121 is formed on the second tunnel section 12.

[0043] According to the ventilation tunnel 1 provided by the embodiment of the first aspect of the present application, its main structure is divided into a first tunnel section 11 and a second tunnel section 12, which are connected to the upstream tunnel 21 and the downstream tunnel 22 respectively. Based on this structure, the airflow can be managed independently in the first tunnel section 11 and the second tunnel section 12, which helps to more effectively control the cross-flow and diffusion of gaseous pollutants. The dirty airflow in the first tunnel section 11 can be discharged outward through the vent 111. When the vehicle flow passes through the vehicle flow entrance of the first tunnel section 11 from the upstream tunnel 21, the dirty flowing air generated by the vehicle flow in the upstream tunnel 21 continues to flow inside the first tunnel section 11. Driven by the vehicle flow, the dirty flowing air in the first tunnel section 11 will rush out from the vent 111, accelerating the outflow of the dirty gas in the first tunnel section 11, and replacing the air in the first tunnel section 11 and even the entire tunnel. , improve the air quality in the first shed tunnel section 11; because the airflow is accelerated to flow outward in the first shed tunnel section 11, when the traffic enters the second shed tunnel section 12, a negative pressure is formed in the second shed tunnel section 12, and the external air can enter the second shed tunnel section 12 through the fresh air inlet 121, so as to realize the introduction of fresh air in the second shed tunnel section 12, and improve the proportion of fresh air in the entire shed tunnel. As the traffic continues to enter the downstream tunnel 22, fresh air can enter the downstream tunnel 22, so as to realize the air renewal of the downstream tunnel 22. Not only ventilation and air exchange are realized, but also the original shading function of the shed tunnel is retained, so as to ensure that the driver can smoothly adapt to the brightness changes when passing through the shed tunnel, reduce visual discomfort, and improve the air quality between tunnels, so as to realize the integration and optimization of functions. In summary, the ventilation shed tunnel 1 provided in the embodiment of the present application can realize the air circulation inside and outside the shed tunnel, promote air replacement, and improve the driving safety and comfort of the driver.

[0044] like Figure 1 to Figure 2 As shown, in some embodiments of the present application, the first shed hole section 11 includes at least two layers of shading plates 13, and the vent 111 is formed between the upper and lower layers of shading plates 13; the second shed hole section 12 includes a layer of shading plates 13. The design of placing the vent 111 between the upper and lower layers of shading plates 13 cleverly utilizes the space, does not affect the shading effect, and can ensure that the dirty air is discharged smoothly, forming a more efficient airflow channel, and accelerating the circulation and replacement of the air inside the first shed hole section 11. The second shed hole section 12 uses a layer of shading plates 13, which ensures a certain degree of shading while making it easier for fresh air to enter.

[0045] like Figure 1As shown, in some embodiments of the present application, a guide plate 14 is provided at the connection between the first shed hole section 11 and the second shed hole section 12; the guide plate 14 extends obliquely upward from the first shed hole section 11 to the top of the second shed hole section 12. The design of the guide plate 14 extending obliquely upward from the first shed hole section 11 to the top of the second shed hole section 12 helps to guide the smooth transition of the airflow. When the vehicle flow enters the second shed hole section 12 from the first shed hole section 11, part of the remaining dirty gas in the first shed hole section 11 is diverted and diffused by the guide plate 14, realizing secondary air replacement and improving air quality. The guide plate 14 can effectively reduce turbulence and make the airflow flow more orderly, thereby improving the overall ventilation efficiency and reducing the noise generated by wind resistance. In addition, the guide plate 14 can also serve as a rainproof device to prevent rainwater from dripping directly to the connection position between the first shed hole section 11 and the second shed hole section 12, protecting the internal road from water erosion, extending the service life of the road and keeping the inside of the shed hole dry.

[0046] In some embodiments of the present application, the angle between the extension direction of the guide plate 14 and the horizontal plane is in the range of 30° to 60°. Within this angle range, the guide plate 14 can guide the airflow to flow upward and discharge in a better way without generating excessive air resistance. If the angle is too small, the airflow guiding effect may be poor, while if the angle is too large, the resistance of air flow may be increased, affecting the ventilation efficiency.

[0047] In some embodiments of the present application, in the first shed section 11, the minimum vertical spacing between the upper and lower shading panels 13 is 1.5 meters, and the maximum vertical spacing is 3.5 meters. A reasonable spacing range allows air to rise and circulate, promotes natural ventilation, and accelerates air replacement. In addition, the spacing between the shading panels 13 also affects the temperature regulation inside the shed. A small spacing helps to block more solar radiation heat energy and keep the inside of the shed cool, while a large spacing is conducive to heat dissipation.

[0048] like Figure 1 to Figure 2As shown, in some embodiments of the present application, in the first shed hole section 11, the upper shading plate 13 is an inverted V-shaped integrated structure, and the lower shading plate 13 is an inverted V-shaped split structure; the projection area of ​​the upper shading plate 13 covers at least part of the area of ​​the lower shading plate 13. The upper shading plate 13 adopts an inverted V-shaped integrated structure, which integrates the shading and structural support functions, reduces the demand for connectors, and improves the stability and aesthetics of the overall structure. The inverted V-shaped design can effectively guide rainwater or snow to flow to both sides, reduce the possibility of water or snow accumulation in the middle, and reduce the structural burden. Moreover, since it is an integrated type, it is more convenient in the production and installation process. The split design of the lower shading plate 13 is conducive to on-site installation and subsequent maintenance and replacement, and the split structure may provide more flexibility to adapt to different installation conditions or adjust the shading angle. The projection area of ​​the upper inverted V-shaped shading plate 13 covers at least part of the lower shading plate 13, further enhancing the shading and rainproof effects.

[0049] like Figure 1 to Figure 2 As shown, in some embodiments of the present application, the lower visor 13 includes a first main body 15 and a second main body 16, and the first main body 15 and the second main body 16 are symmetrically distributed; a hollow area connected to the vent 111 is formed between the first main body 15 and the second main body 16; the upper visor 13 corresponds to the hollow area. The first main body 15 and the second main body 16 are symmetrically distributed, which not only ensures the balanced aesthetic feeling of the structure, but also simplifies the production and installation process through mirror symmetry, and the symmetry helps to evenly distribute the wind pressure and weight borne by the visor 13, and enhance the overall stability and durability. The hollow area formed between the first main body 15 and the second main body 16, as a flow channel for airflow, allows natural airflow to pass through, helps to improve the air circulation in the first shed section 11, reduces dirty airflow and stuffiness, and improves the comfort of the driver.

[0050] like Figure 1 to Figure 2 As shown, in some embodiments of the present application, the opening of the vent 111 faces both sides of the ventilation shed hole 1; the opening of the fresh air inlet 121 faces both sides of the ventilation shed hole 1. By opening the vent 111 and the fresh air inlet 121 toward both sides of the shed hole, the airflow driven by the natural wind direction and the traffic flow can be better utilized to promote the lateral flow of air inside the shed hole, thereby more efficiently exchanging gases, quickly removing the dirty air accumulated in the shed hole, and introducing fresh air to improve the air quality of the entire space. Compared with the top or bottom openings, the side openings can more directly utilize the natural wind force of the external environment and reduce the auxiliary energy required for ventilation, thereby achieving the purpose of energy saving and emission reduction. At the same time, the side openings make the airflow path shorter, reduce the airflow resistance, and improve the ventilation efficiency. The opening design facing both sides can reduce the wind noise interference directly generated to the moving vehicle and ensure the quietness of driving.

[0051] In some embodiments of the present application, the extension length of the first shed tunnel section 11 is greater than the extension length of the second shed tunnel section 12. The first shed tunnel section 11 undertakes the main task of discharging the polluted air in the upstream tunnel 21. The longer extension length can provide a more sufficient area to accelerate the airflow, ensure that the polluted air can be effectively and quickly discharged, improve the ventilation efficiency, and reduce the residence time of pollutants in the first shed tunnel section 11, thereby improving the air quality. Fresh air is introduced into the second shed tunnel section 12. Once the fresh air enters the second shed tunnel section 12, it can quickly mix with the existing air in the second shed tunnel section 12 and be naturally distributed to the downstream tunnel 22 as the traffic advances. The shorter second shed tunnel section 12 helps to control the mixing ratio of fresh air and polluted air, and avoid excessive concentration or uneven distribution of fresh air. The first shed tunnel section 11 requires a longer structure to fully realize the effective discharge of pollutants, while the function of the second shed tunnel section 12 is relatively simple, mainly to introduce external air, so its length does not need to be too long, so that the overall construction cost and maintenance cost can be controlled while meeting the functional requirements.

[0052] In addition, the inclination angle of the vent 111, the guide plate 14 and the fresh air inlet 121 can be adjusted according to the cross-flow ratio control parameter to meet the ventilation requirements of the shed tunnel 1, the upstream tunnel 21 and the downstream tunnel 22, reduce the number of ventilation fans and operating energy consumption, and achieve low-carbon and environmentally friendly effects. The cross-flow ratio refers to the ratio of the dirty air in the upstream tunnel 21 entering the downstream tunnel 22.

[0053] like Figures 1 to 3 As shown, the ventilation shed 1 provided in the embodiment of the present application further includes an arch frame 17, which is distributed at intervals along the extension direction of the shed. The arch frame 17 is the main frame structure of the ventilation shed 1, and is used to support the sunshade 13.

[0054] like Figure 4 As shown, the second aspect embodiment of the present application provides a tunnel group 2, including an upstream tunnel 21, a downstream tunnel 22 and the ventilation shed hole 1 in any embodiment of the first aspect mentioned above; the ventilation shed hole 1 is connected to the upstream tunnel 21 and the downstream tunnel 22.

[0055] According to the tunnel group 2 provided by the embodiment of the second aspect of the present application, the ventilation shed tunnel 1 therein is divided into a first shed tunnel section 11 and a second shed tunnel section 12, which are connected to the upstream tunnel 21 and the downstream tunnel 22 respectively. Based on this structure, the airflow can be managed independently in the first shed tunnel section 11 and the second shed tunnel section 12, which helps to more effectively control the cross-flow and diffusion of gaseous pollutants. The dirty airflow in the first shed tunnel section 11 can be discharged outward through the vent 111. When the traffic passes through the traffic entrance of the first shed tunnel section 11 from the upstream tunnel 21, the dirty flowing air generated by the traffic in the upstream tunnel 21 continues to flow inside the first shed tunnel section 11. Driven by the traffic, the dirty flowing air in the first shed tunnel section 11 will rush out from the vent 111, accelerating the outflow of the dirty gas in the first shed tunnel section 11, and replacing the air in the first shed tunnel section 11 and even the entire shed tunnel. , improve the air quality in the first shed tunnel section 11; because the airflow in the first shed tunnel section 11 is accelerated to flow outward, when the traffic enters the second shed tunnel section 12, a negative pressure is formed in the second shed tunnel section 12, and the external air can enter the second shed tunnel section 12 through the fresh air inlet 121, so as to realize the introduction of fresh air in the second shed tunnel section 12, and improve the proportion of fresh air in the entire shed tunnel. As the traffic continues to enter the downstream tunnel 22, fresh air can enter the downstream tunnel 22, so as to realize the air renewal of the downstream tunnel 22. Not only ventilation and air exchange is realized, but also the original shading function of the shed tunnel is retained, ensuring that the driver can smoothly adapt to the brightness changes when passing through the shed tunnel, reducing visual discomfort, and at the same time improving the air quality between tunnels, realizing the integration and optimization of functions. In summary, the tunnel group 2 provided in the embodiment of the present application can realize air replacement and improve the driving safety and comfort of the driver.
