Technical Field
[0001] This utility model relates to the field of tunnel portal water diversion technology, and in particular to a bamboo-cutting tunnel portal water diversion structure. Background Technology
[0002] The portal of a highway tunnel is a crucial component at the tunnel entrance, serving functions such as support, drainage, aesthetics, protection, and traffic guidance to ensure the safe operation of the tunnel. Highway tunnel portals typically come in various types to adapt to different geological conditions, terrain environments, engineering requirements, and economic factors; the bamboo-cut portal is one of the most common highway tunnel portal structures.
[0003] The existing bamboo-cut cave entrance facade has a gentle 1:1 slope, which makes rainwater flow slowly on the facade. As a result, rainwater tends to accumulate and overflow, and some of the overflowing rainwater flows into the cave, causing serious pollution to the interior decorations. It can also cause the interior decorations to peel and fall off due to being soaked in rainwater.
[0004] Therefore, it is necessary to propose a bamboo-cutting type tunnel entrance 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 bamboo-cut cave entrances, so as to solve the problem that the lack of a water guiding mechanism in the existing bamboo-cut cave entrances causes water to accumulate and then overflow into the cave.
[0006] To achieve the above objectives, this utility model provides a bamboo-cutting type cave entrance water guiding structure, including a cave entrance ring frame and a water guiding component, wherein the water guiding component is connected to the cave entrance ring frame; wherein,
[0007] The water guiding component is disposed outside the portal ring frame. The water guiding component is abutted and connected to the inner and outer sides of the portal ring frame. One end of the water guiding component along the tunnel extension direction is spaced apart from the portal ring frame. The other end of the water guiding component along the tunnel extension direction is recessed towards the portal ring frame to form a water guiding groove, and the water guiding groove extends circumferentially along the portal ring frame.
[0008] Preferably, the water guiding assembly is U-shaped and includes an outer end plate, a side end plate, and an inner end plate. The outer end plate is disposed on the outside of the tunnel portal ring frame, the inner end plate is disposed on the inside of the tunnel portal ring frame, the side end plates are spaced apart on one side of the tunnel portal ring frame along the tunnel extension direction, and the water guiding channel is disposed on the side end plate.
[0009] Preferably, the cross-section of the water guide channel is trapezoidal, and the water guide channel is inclined on both sides along the radial direction of the tunnel.
[0010] Preferably, the inner end plate is located in a section between the portal ring frame and the side end plate, and is inclined towards the inside of the portal ring frame.
[0011] Preferably, the water guide channel is located near the inner side of the portal frame.
[0012] Preferably, the length of the inclined side of the water guide channel on the inner side near the portal ring frame is greater than the length of the inclined side on the inner side away from the portal ring frame.
[0013] Preferably, the inner end plate is bolted through the water guiding assembly and extends into the portal ring frame to connect with the portal ring frame.
[0014] Preferably, the outer end plate is glued to the side of the portal frame.

[0016] Preferably, the inclination angle of the section of the inner end plate located between the portal frame and the side end plate is 8° to 10°.
[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] The present invention provides a bamboo-cutting type tunnel portal water guiding structure, including a tunnel portal ring frame and a water guiding component. The water guiding component is connected to the tunnel portal ring frame and is disposed outside the tunnel portal ring frame. The water guiding component is abutted and connected to the inner and outer sides of the tunnel portal ring frame. One end of the water guiding component along the tunnel extension direction is spaced apart from the tunnel portal ring frame. The other end of the water guiding component along the tunnel extension direction is recessed towards the tunnel portal ring frame to form a water guiding groove, and the water guiding groove extends circumferentially along the tunnel portal ring frame. By placing the water-guiding components outside the archway frame, the sloping facade of the bamboo-shaped archway slows down the flow of rainwater, guiding the overflowing rainwater along the facade. When the rainwater flows down the facade of the water-guiding components to the water-guiding channel, it is diverted to the drainage ditch, preventing rainwater from soaking the decorations inside the archway. This significantly improves the rainwater guiding capacity of the archway, avoids the problem of rainwater accumulating on the archway and causing excessive potential energy during rainwater scouring, extends the service life of the decorations inside the archway, and reduces maintenance costs.

[0031] Please see the appendix Figure 1-4 This utility model provides a bamboo-cutting cave entrance water-guiding structure in one embodiment, including a cave entrance ring frame 10 and a water-guiding component 20, wherein the water-guiding component 20 is connected to the cave entrance ring frame 10. First, it should be noted that in this application, the inner and outer sides refer to the area within the radial direction of the bamboo-cutting cave entrance ring frame 10 as the boundary, and the area outside the radial direction of the cave entrance ring frame 10 as the outer side. This differs from the prior art where the bamboo-cutting cave entrance facade has a gentle 1:1 slope, resulting in slower rainwater flow on the facade and a tendency for overflow. Some of the overflowing rainwater flows into the cave, causing serious pollution to the interior decorations and causing them to peel and flake off due to rainwater immersion. This application solves the above-mentioned defects in the prior art by providing a bamboo-cutting cave entrance water-guiding structure, as detailed below:
[0032] The water guiding component 20 is disposed outside the portal ring frame 10. The water guiding component 20 is abutted and connected to the inner and outer sides of the portal ring frame 10. One end of the water guiding component 20 along the tunnel extension direction is spaced apart from the portal ring frame 10. One end of the water guiding component 20 along the tunnel extension direction is recessed towards the portal ring frame 10 to form a water guiding groove 221, and the water guiding groove 221 extends circumferentially along the portal ring frame 10.
[0033] Specifically, the bamboo-cutting tunnel portal water diversion structure in this application includes a portal ring frame 10 and a water diversion component 20. The portal ring frame 10 is the structure at the entrance of the bamboo-cutting tunnel portal. During the rainy season, because the slope of the bamboo-cutting tunnel portal is relatively gentle, rainwater flows slowly and tends to accumulate on the portal. When the accumulated water reaches a certain amount and flows downward, it generates a large potential energy, which can affect passing vehicles. Therefore, it is necessary to install the water diversion component 20 to divert rainwater to the drainage outlets on both sides of the tunnel. To prevent rainwater from overflowing at the drainage ditch; during connection, the water guiding component 20 is abutted against the inner and outer sides of the tunnel portal frame 10, so that the water guiding component 20 covers the outside of the tunnel portal frame 10, and one end of the water guiding component 20 along the tunnel extension direction is recessed towards the tunnel portal frame 10 to form a water guiding groove 221 for water diversion. Therefore, one end of the water guiding component 20 along the tunnel extension direction needs to be spaced apart from the tunnel portal frame 10 to ensure that the water guiding groove 221 has space to be set.
[0034] Due to the inclined design of the bamboo-cut tunnel portal, when rainwater flows along the vertical surface of the water guiding component 20, the flowing rainwater will flow into the water guiding channel 221. The water guiding channel 221 extends circumferentially along the portal frame 10, allowing the rainwater to follow the circular flow of the portal frame 10 and flow to the drainage ditches at the bottom of both sides of the tunnel, thus achieving the effect of diverting and guiding rainwater.
[0035] In a preferred embodiment of the present invention, the water guiding component 20 is U-shaped and includes an outer end plate 210, a side end plate 220 and an inner end plate 230. The outer end plate 210 is disposed on the outside of the portal ring frame 10, the inner end plate 230 is disposed on the inside of the portal ring frame 10, the side end plates 220 are spaced apart on one side of the portal ring frame 10 along the tunnel extension direction, and the water guiding groove 221 is disposed on the side end plate 220.
[0036] It should be noted that the U-shaped water guiding component 20 can completely cover the portal ring frame 10. In addition to guiding water, it can also play a good waterproof role to protect the structural strength of the water guiding component 20. It can be understood that during installation, its outer end plate 210 is used to abut against the outside of the portal ring frame 10, and the inner end plate 230 is used to abut against the inside of the portal ring frame 10 to cover the inner and outer sides of the portal ring frame 10 in the radial direction. The side end plate 220 is spaced apart from the portal ring frame 10 along the tunnel extension direction so that the water guiding groove 221 on the side end plate 220 can be set in this space.
[0037] In a preferred embodiment of the present invention, the cross-section of the water guide channel 221 is trapezoidal, and the water guide channel 221 is inclined on both sides along the radial direction of the tunnel.
[0038] It should be noted that the trapezoidal cross-section of the water channel 221 may have two inclined sides. In this application, the two inclined sides of the trapezoid are the two sides of the water channel 221 along the radial direction of the tunnel. In this way, after rainwater overflows into the water channel 221, it continues to move inward due to inertia. Due to the slope of the inclined side of the water channel 221, the potential energy of the rainwater can be effectively dissipated. Even if the scouring potential energy of some rainwater is still too large, under the action of the inclined side near the inner side of the tunnel entrance frame 10, the direction of the rainwater will change after leaving the water channel 221, so as to avoid flowing into the interior decoration surface of the tunnel. Preferably, the depth of the water channel 221 can be 5cm to 6cm to provide sufficient water guiding space and space to buffer the potential energy of the rainwater.
[0039] In a preferred embodiment of the present invention, the inner end plate 230 is located between the portal ring frame 10 and the side end plate 220, and is inclined toward the inside of the portal ring frame 10 towards the side end plate 220.
[0040] It is worth noting that by forming a reverse tilt angle at the inner corner of the U-shaped plate, rainwater can be further prevented from overflowing onto the inner wall of the hole. Preferably, this tilt angle can be set to 8° to 10°, and those skilled in the art can select it according to actual needs.
[0041] In a preferred embodiment of this utility model, the water guide channel 221 is disposed near the inner side of the portal frame 10.
[0042] It is worth noting that this means that if some of the water in the water guide channel 221 fails to be effectively guided and flows out of the water guide channel 221, it can flow directly out along the inclined side of the inner side of the water guide channel 221. However, if it is not set near the inner side of the cave entrance ring frame 10, it may overflow and flow into the inner side of the cave entrance ring frame 10, which will affect the decoration inside the cave.
[0043] Furthermore, the length of the inclined side of the water guide channel 221 near the inner side of the portal frame 10 is greater than the length of the inclined side away from the inner side of the portal frame 10.
[0044] It should be noted that this results in a larger contact area for the inner inclined side and a gentler slope compared to the shorter inclined side. The gentler slope on the inner side can more effectively dissipate the scouring potential energy of rainwater. Preferably, the length of the inner inclined side can be 10cm, while the length of the outer inclined side can be 5cm.
[0045] Furthermore, the inner end plate 230 passes through the water guiding assembly 20 and extends into the portal ring frame 10 via bolts 240 to connect with the portal ring frame 10.
[0046] It should be understood that the inner end plate 230 is more securely connected by bolts 240, and is easier to install. It is also easier to disassemble and reassemble during later maintenance and replacement. The bolts 240 can be arranged at intervals along the extension direction of the bottom plate of the water guide assembly 20 to ensure the stability of the connection of each part.
[0047] Furthermore, the outer end plate 210 is glued to the side of the portal frame 10.
[0048] It should be noted that the outer end plate 210 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.
[0049] 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.
