Description

Technical Field

[0001] This utility model relates to the field of tunnel portal technology, and in particular to a water guiding structure for an end-wall type tunnel portal. Background Technology

[0002] The portal structure of a highway tunnel is an important component of the tunnel entrance, mainly used to protect the entrance, stabilize the side slopes, divert surface water flow, and decorate the entrance. Depending on different geological conditions, terrain features, and engineering requirements, there are various types of portal structures, with the end-wall type being one of the most common forms.

[0003] The existing end-wall type portal facade has a steep slope of 10:1 and usually does not have a water guiding structure. As a result, during the rainy season, rainwater will slide down the portal facade quickly due to gravity. The rainwater will spread along the portal facade and some of it will flow into the cave, causing serious pollution to the interior decoration. Some interior decorations may even peel off due to being soaked in rainwater. In severe cases, it may also affect the structural strength of the portal.

[0004] Therefore, it is necessary to propose an end-wall type portal water diversion structure to solve or at least alleviate the above-mentioned defects. Utility Model Content

[0005] The main purpose of this utility model is to provide a water guiding structure for end-wall type portals to solve the problem that the lack of a water guiding structure in the existing end-wall type portals leads to the impact of rainwater soaking inside the portal.

[0006] To achieve the above objectives, this utility model provides an end-wall type portal water guiding structure, including a tunnel portal body and a water guiding assembly, wherein the water guiding assembly is connected to the tunnel portal body; wherein,

[0007] The tunnel portal body includes a portal frame and a tunnel roof wall, with the portal frame connected to the lower part of the tunnel roof wall;

[0008] The water guiding component is disposed outside the portal ring frame. The top end of the water guiding component is connected to the side of the portal ring frame and is disposed close to the top wall of the portal. The bottom end of the water guiding component is connected to the bottom of the portal ring frame. The side of the water guiding component protrudes outward to form a water guiding ridge, and the water guiding ridge extends along the circumferential direction of the portal ring frame.

[0009] Preferably, the water guiding component is L-shaped.

[0010] Preferably, the water guide rib is semi-circular and is located near the bottom side of the water guide assembly.

[0011] Preferably, the bottom of the water guiding component near the outer side of the portal frame is further provided with a downward protruding water guiding groove, which is arc-shaped.

[0012] Preferably, the side of the water guiding assembly is inclined downward from the top toward the side away from the portal frame.

[0013] Preferably, the bottom of the water guiding component is inclined downwards from the end closest to the inside of the tunnel toward the water guiding channel.

[0014] Preferably, the bottom end of the water guiding component is bolted through the water guiding component and extends into the portal ring frame to connect with the portal ring frame.

[0015] Preferably, the top of the water guiding component is glued to the side of the portal ring frame.

[0016] Preferably, the radius of the water guide rib is 2.5cm to 2.7cm.

[0017] Preferably, the slope ratio of the side of the water guiding component is 20:1.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This utility model provides a tunnel portal water-guiding structure, including a tunnel portal body and a water-guiding component. The water-guiding component is connected to the tunnel portal body, which includes a portal ring frame and a tunnel top wall. The portal ring frame is connected to the lower part of the tunnel top wall. The water-guiding component is disposed outside the portal ring frame, with its top end connected to the side of the portal ring frame and positioned close to the tunnel top wall, and its bottom end connected to the bottom of the portal ring frame. A water-guiding ridge protrudes outward from the side of the water-guiding component, extending circumferentially along the portal ring frame. By placing the water-guiding component outside the portal ring frame, rainwater overflowing from the portal facade is guided. When the rainwater flows down the facade of the water-guiding component to the water-guiding ridge, it is diverted to the drainage ditch, preventing rainwater from soaking the interior decorations. This significantly improves the rainwater drainage capacity of the portal, extends the service life of the interior decorations at the portal, and reduces maintenance costs.

[0032] Please see the appendix Figure 1-3This utility model provides an end-wall type portal water guiding structure, including a tunnel portal body 10 and a water guiding component 20, wherein the water guiding component 20 is connected to the tunnel portal body 10. First, it should be noted that, unlike existing end-wall type portals which typically lack a water guiding structure on the facade, this design addresses the shortcomings of the prior art by providing an end-wall type portal water guiding structure, as follows:

[0033] The tunnel portal body 10 includes a portal frame 110 and a tunnel top wall 120. The portal frame 110 is connected to the lower part of the tunnel top wall 120. The water guiding component 20 is disposed around the portal frame 110. The top end of the water guiding component 20 is connected to the side of the portal frame 110 and is disposed close to the tunnel top wall 120. The bottom end of the water guiding component 20 is connected to the bottom of the portal frame 110. The side of the water guiding component 20 protrudes outward to form a water guiding ridge 210, and the water guiding ridge 210 extends circumferentially along the portal frame 110.

[0034] Specifically, the end-wall type portal water guiding structure in this application includes a tunnel portal body 10 and a water guiding component 20. The tunnel portal body 10 is mainly used in end-wall type portal structures, specifically including a portal ring frame 110 and a tunnel top wall 120. Since rainwater mainly flows along the portal facade during the rainy season, and some rainwater flows into the tunnel along with the portal ring frame 110, a water guiding component 20 is needed to divert rainwater to a drainage point to prevent overflow. During connection, the top end of the water guiding component 20 is connected to the top side of the portal ring frame 110 (i.e., near the tunnel top wall 120). (Position 20) In this way, when rainwater flows down from the top wall 120 of the tunnel, it can be guided by the water guiding component 20 without contacting the tunnel entrance ring frame 110, thus better covering and protecting the outside of the tunnel entrance ring frame 110; the bottom end of the water guiding component 20 is connected to the bottom of the tunnel entrance ring frame 110, extending inward to the inner bottom end of the tunnel entrance ring frame 110 to achieve a complete covering effect. Therefore, preferably, the water guiding component 20 can be set in an L-shape, which can better form the above-mentioned covering form to cover the outside of the tunnel entrance ring frame 110. Please refer to the appendix for details. Figure 1 .

[0035] Wherein, after the water guiding component 20 is installed over the outer side of the tunnel entrance ring frame 110, the water can be guided by the water guiding ridge 210 protruding on the water guiding component 20. The water guiding ridge 210 protrudes from the side of the water guiding component 20. When rainwater flows down from the tunnel top wall 120, the rainwater flows down along the outer side wall of the water guiding component 20. After the flowing rainwater comes into contact with the water guiding ridge 210, it flows away along the protruding structure of the water guiding ridge 210, thereby achieving the effect of guiding water. It can be understood that the water guiding ridge 210 extends circumferentially along the tunnel entrance ring frame 110 and is also arched, so as to achieve a comprehensive water guiding effect on the tunnel entrance ring frame 110. It is worth mentioning that the water guiding ridge 210 can be set 10cm above the inner edge of the tunnel lining structure.

[0036] In a preferred embodiment of the present invention, the water guide rib 210 is semi-circular and is disposed near the bottom side of the water guide assembly 20.

[0037] It is important to note that the semi-circular structure allows some rainwater to flow away along the raised surface during rainwater drainage. When it is not raining, the curved surface of the semi-circle allows accumulated water on the water guide ridge 210 to slide down to the ground surface, thus preventing long-term water accumulation on the water guide ridge 210. If the size of the water guide ridge 210 is too small, the drainage effect will be poor; if it is too large, rainwater accumulation will be severe and costs will increase. Therefore, preferably, the radius of the water guide ridge 210 can be set to 2.5cm to 2.7cm, which can be set by those skilled in the art according to actual conditions. It is understood that the water guide ridge 210 is positioned near the bottom side of the water guiding component 20 to provide a slow flow process when rainwater falls to the ground surface, avoiding excessive impact on the ground due to its height, which could affect traffic.

[0038] In a preferred embodiment of the present invention, the bottom of the water guiding component 20 near the outer side of the portal frame 110 is further provided with a downwardly protruding water guiding groove 220, which is arc-shaped.

[0039] It is worth noting that, considering the permeability of rainwater, some water will still seep down and overflow to the outer surface of the tunnel portal frame 110. This seepage also includes water from the tunnel entrance. Therefore, a water guide trough 220 is formed by protruding downwards at the bottom of the water guide assembly 20 near the outer side of the tunnel portal frame 110. The water guide trough 220 is used to receive and discharge some of the seepage. After the seepage flows into the interior, it falls into the water guide trough 220 and is then guided to the drainage point. The water guide trough 220 is also designed in an arc shape to facilitate drainage. Preferably, it can be set to 1.5cm to 1.7cm, and the specific value can be selected according to actual needs.

[0040] In a preferred embodiment of the present invention, the side of the water guiding component 20 is inclined downward from the top toward the side away from the portal frame 110.

[0041] It is worth noting that, in order to facilitate the flow of rainwater from the top wall 120 of the hole to the top of the water guiding component 20, the slope makes it easier to guide the water to the water guiding ridge 210, resulting in a better water guiding effect. Preferably, the slope ratio can be set to 20:1, and the specific degree of inclination can be selected by those skilled in the art according to actual needs.

[0042] Furthermore, the bottom of the water guiding component 20 is inclined downwards from the end closest to the inside of the tunnel toward the water guiding channel 220.

[0043] It should be noted that, considering that tunnel seepage from the portal frame 110 itself can be easily diverted to the water guide channel 220, the bottom plate of the water guide component 20 also needs to be inclined towards the water guide channel 220 so that water accumulated in the portal frame 110 near the inner side of the tunnel can flow towards the water guide channel 220. Preferably, the inclination of the bottom plate of the water guide component 20 near the water guide channel 220 can be set to 1% to 2%, while the inclination of the bottom plate of the water guide component 20 away from the water guide channel 220 can be more inclined to facilitate outflow, and can be set to 5% to 10%.

[0044] Furthermore, the bottom end of the water guiding component 20 is connected to the portal ring frame 110 by a bolt 230 passing through the water guiding component 20 and extending into the portal ring frame 110.

[0045] It should be understood that the bottom end of the water guiding component 20 is connected with bolts 230 for a more stable connection and easier installation. It is also convenient to disassemble and reassemble during later maintenance and replacement. The bolts 230 can be arranged at intervals along the extension direction of the bottom plate of the water guiding component 20 to ensure stable connection of each part.

[0046] Furthermore, the top of the water guiding component 20 is glued to the side of the portal frame 110.

[0047] It should be noted that the top of the water guiding component 20 is connected by adhesive, which not only ensures a stable connection, but also provides a certain degree of sealing to prevent rainwater from seeping into the interior of the water guiding component 20.

[0048] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
