Description

Technical Field

[0001] The present invention relates to the technical field of tunnel engineering, in particular to a transition section connection device and a usage method at the junction of a tunnel subgrade and a highway subgrade. Background Art

[0002] At the junction of a highway subgrade and a tunnel subgrade, also called the road-tunnel transition section, due to the relatively dim light inside the tunnel and the large difference in ambient light from the outside of the tunnel, when driving during the day, the human eye is not suitable for such a change in light intensity, which easily leads to the problem of not being able to clearly see the surrounding roadblocks. At the same time, the lights in the tunnel are generally installed on the top inside the tunnel, and the illumination of the tunnel road surface is insufficient. Especially when driving out of the tunnel entrance, due to the strong external ambient light, it is easy to cause the driver to be dazzled, resulting in the driver not being able to clearly see the road surface condition of the road-tunnel transition section, and thus it is easy to cause traffic accidents at the road-tunnel transition section.

[0003] Therefore, we propose a transition section connection device and a usage method at the junction of a tunnel subgrade and a highway subgrade to solve the above problems. Utility Model Content

A protective plate is detachably connected between the first guiding pile and the second guiding pile, and a light box is arranged at the front side below the protective plate. A plurality of lighting components are evenly distributed on the front surface of the light box, and the light box is connected to the first guiding pile through a disassembly and assembly structure, which is used for quickly disassembling and assembling the light box for replacement and maintenance;

[0007] The lighting component includes a downlight, a plurality of LED lamp beads distributed on the outer circumference of the downlight, and a detection module, and the detection module includes a photosensitive sensor and a dustiness detection sensor.

[0008] In a further embodiment, a cleaning component is arranged at the rear side of the light box. The cleaning component includes a water supply structure, a water pipe, and nozzles evenly distributed along the length direction of the water pipe. The positions of the nozzles correspond to the positions of the lighting components one by one.

[0010] In a further embodiment, liquid collecting hoppers communicating with the interior of the liquid storage tank are connected to the upper ends of the first guiding pile and the second guiding pile, a filter net is installed inside the liquid collecting hopper, a guiding plate is connected between adjacent liquid collecting hoppers, and one end of the guiding plate close to the second guiding pile inclines downward.

[0011] In a further embodiment, a reflective coating in the shape of an arrow is provided on the front surface of the protection plate, a plurality of elastic members are installed inside the protection plate, slots are formed in the sides of the first guiding pile and the second guiding pile, and inserting strips fixedly connected to the slots are provided at both ends of the protection plate.

[0012] In a further embodiment, concrete bases are provided at the bottoms of the first guiding pile and the second guiding pile, the first guiding pile and the second guiding pile are connected to the concrete bases through bolts, embedded steel bars are provided inside the concrete bases, and one ends of the embedded steel bars far away from the concrete bases extend into the ground.

[0013] In a further embodiment, the disassembly and assembly structure includes a first connecting rod, a second connecting rod and a central block. The central block is connected to the light box through a spring piece, and telescopic rods are symmetrically connected to the front and rear ends of the central block.

[0014] In a further embodiment, one end of the first connecting rod extending into the first guiding pile is connected with a flipping structure.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. The first guiding pile and the second guiding pile in the present invention are arranged at the road shoulders of the road-tunnel transition section and are symmetrically arranged on both sides of the roadside of the road-tunnel transition section. The road surface is irradiated by the lighting components in the light box, so that the road surface of the road-tunnel transition section is clearer, which is convenient for drivers to observe, and further prevents the driver from being dazzled and unable to see the road surface condition of the road-tunnel transition section clearly, thereby effectively reducing the occurrence of traffic accidents at the road-tunnel transition section.

[0018] 2. To further optimize the illumination effect of the lighting component, the present invention is provided with downlights and LED lamp beads. The downlights have a large illumination area to better illuminate the road surface during the day. However, at night, since the light intensity change inside and outside the tunnel is not obvious, the illumination of the downlights is likely to cause glare to the drivers. Therefore, at this time, the downlights are turned off and only the LED lamp beads flash yellow light for warning and reminder, which is convenient for better guiding vehicles through the road-tunnel transition section.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0030] Please refer to Figure 1-3 , a transition section connection device at the junction of a tunnel subgrade and a highway subgrade, including a first guiding pile 1 and a second guiding pile 2. The first guiding pile 1 is arranged between two second guiding piles 2, and their structures are the same. A protective plate 3 is detachably connected between the first guiding pile 1 and the second guiding pile 2. A reflective coating 31 in the shape of an arrow is provided on the front surface of the protective plate 3, so that when the vehicle shines on the reflective coating 31, it can reflect light, facilitating the guiding of the vehicle to travel, preventing the visual difference of the driver due to the light difference at the road-tunnel transition section, making it difficult to judge the side distance, and reducing the problem of vehicle deviation and collision. A number of elastic members 32 are installed inside the protective plate 3. The elastic members 32 can be springs or elastic sheets, but are not limited to these two elastic structures. Once the vehicle inevitably collides with the protective plate 3, the elastic members 32 can buffer the impact force, thereby playing a certain anti-collision effect. Slots 13 are provided on the sides of the first guiding pile 1 and the second guiding pile 2, and insertion strips 33 that can be inserted into the slots 13 are fixed at both ends of the protective plate 3. The insertion strips 33 are inserted into the slots 13 from top to bottom, so that the protective plate 3 is connected to the guiding pile by insertion, which is convenient for later disassembly, replacement, and installation;

[0031] Please refer to Figure 1-2 , a light box 4 is provided on the front side below the protective plate 3. A number of lighting components 5 are evenly distributed on the front surface of the light box 4. In order to better protect the lighting components 5, the outside is encapsulated with tempered glass. The lighting components 5 include downlights 51 with a large irradiation area and a number of LED lamp beads 52 that can flash yellow light distributed on the outer circumference of the downlights 51. And a detection module 53 is connected below the lighting components 5. The detection module 53 includes a photosensitive sensor and a dustiness detection sensor. The photosensitive sensor is used to detect the ambient light brightness to judge whether it is day or night, and then switch the use of the downlights 51 and the LED lamp beads 52. The dustiness detection sensor is used to monitor the dust amount outside the lighting components 5;

[0032] Please refer to Figure 1-2 , considering that the height of the light box 4 is set relatively low, close to the ground, with a large amount of dust and easy to accumulate dust on the surface. Long-term dust accumulation affects the lighting brightness. A cleaning component is provided on the rear side of the light box 4. The cleaning component includes a water supply structure, a water pipe 10 and a number of nozzles 11 evenly distributed along the length direction of the water pipe 10. The water pipe 10 is fixed to the backs of the first guiding pile 1 and the second guiding pile 2. There is enough space for the light box 4 to flip between the water pipe 10 and the light box 4. The positions of the nozzles 11 correspond to the positions of the lighting components 5 one by one. The surface of the lighting components 5 is cleaned through the nozzles 11 to remove floating dust;

[0033] Please refer to Figure 3-4 , the water supply structure is an internal liquid storage tank 12 hidden inside the guiding pile. The liquid storage tank 12 is not only used for storing water, but also can increase the weight of the first guiding pile 1 and the second guiding pile 2 to make them more stable. The water outlet of the liquid storage tank 12 is connected to a high-pressure pump 14. One end of a hose 15 is installed at the lower end of the high-pressure pump 14. The other end of the hose 15 passes through the guiding pile and is connected to the water pipe 10. Through the high-pressure pump 14, water can not only be delivered to the nozzles 11, but also the water can be pressurized so that the water sprayed by the nozzles 11 has a greater pressure and a better cleaning effect;

[0034] Please refer to Figure 1-4 , considering that the liquid storage capacity inside the liquid storage tank 12 is limited, and at the same time, the consumption of waterway materials for laying on the highway is relatively large. The upper ends of the first guiding pile 1 and the second guiding pile 2 are both connected with liquid collecting hoppers 8 that communicate with the inside of the liquid storage tank 12. The liquid collecting hoppers 8 are used to collect rainwater. And a filter screen 81 is installed inside the liquid collecting hoppers 8 to filter the rainwater. A guide plate 9 is connected between adjacent liquid collecting hoppers 8. And one end of the guide plate 9 close to the second guiding pile 2 is inclined downward. Since the first guiding pile 1 and the second guiding pile 2 are arranged in the road-tunnel transition section, a part remains inside the tunnel and cannot receive rainwater, while the other part is arranged outside the tunnel and can collect rainwater. The rainwater can be diverted through the guide plate 9 so that the second guiding pile 2 remaining inside the tunnel can also store rainwater.

[0035] Please refer to Figure 4-5 Figure 4-5 , in order to improve the stability of the fixation of the first guide pile 1 and the second guide pile 2, concrete bases 7 are provided at the bottoms of the first guide pile 1 and the second guide pile 2, and the first guide pile 1 and the second guide pile 2 are connected to the concrete bases 7 by bolts. Embedded steel bars 71 are arranged inside the concrete bases 7. The embedded steel bars 71 are in a T-shaped structure, with one end wrapped inside the concrete bases 7 and the other end extending into the ground, thereby improving the stability of the combination of the concrete bases 7 and the ground.

[0036] Please refer to Figure 4-5 Figure 4-5 , considering that the service life of the light box 4 is limited, it is set that the light box 4 is connected to the first guide pile 1 through a disassembly and assembly structure 6. The disassembly and assembly structure 6 includes a first connecting rod 61, a second connecting rod 62 and a central block 63. The central block 63 is a non-circular structure to prevent slipping between it and the light box 4. One end of the central block 63 extending out of the light box 4 is connected to the second connecting rod 62, and the end of the second connecting rod 62 away from the central block 63 is connected to the first connecting rod 61. One end of a spring piece 64 is installed at the end of the central block 63 facing the inside of the light box 4, and the other end of the spring piece 64 contacts but is not fixed to the light box 4. One end of the first connecting rod 61 extending into the first guide pile 1 is connected to a flipping structure 16. The flipping structure 16 includes a servo motor 161 fixed to the concrete base 7, rotating rods 162 symmetrically connected to the output shafts on both sides of the servo motor 161, and a controller 163 installed on the front side of the concrete base 7 and electrically connected to the servo motor 161. The rotating rods 162 and the first connecting rod 61 can be inserted and connected. The flipping structure 16 can not only adjust the irradiation angle of the light box 4, but also flip the light box 4 to make its cleaning more thorough. A bearing 17 is installed at the connection between the first guide pile 1 and the second connecting rod 62, and the inner bushing of the bearing 17 can be inserted and connected to the second connecting rod 62. By squeezing the spring piece 64, the first connecting rod 61 and the second connecting rod 62 can be retracted into the light box 4, so as to be separated from the rotating rods 162 and the bearing 17, thereby facilitating the light box 4 to be stuck between the first guide pile 1 and the second guide pile 2, making its disassembly and assembly convenient and facilitating later maintenance and replacement;

[0037] Please refer to Figure 5-7, To further facilitate the use of the disassembly and assembly structure 6, making the operation of the disassembly and assembly structure 6 convenient and facilitating the internal maintenance of the disassembly and assembly structure 6, telescopic rods 65 are symmetrically connected to the front and rear ends of the central block 63. The telescopic rods 65 penetrate the surface of the light box 4, and a rectangular movable groove is provided at the connection between the light box 4 and the telescopic rods 65. The telescopic rods 65 can slide along the rectangular movable groove through the rectangular movable groove, thereby facilitating the manipulation of the central block 63 to move and contract. The telescopic rods 65 include end rods 651 and insertion cylinders 652 that are inserted into each other. The insertion cylinder 652 is fixed to the central block 63, and the end rod 651 and the insertion cylinder 652 can be telescoped to facilitate shortening the length of the telescopic rod 65 so that it can be withdrawn from the inside of the rectangular movable groove, facilitating the disassembly of the disassembly and assembly structure 6. Moreover, the end rod 651 and the insertion cylinder 652 are connected by a spring 653, and the elastic action of the spring 653 is used to conveniently reset the length of the telescopic rod 65.

[0038] Please refer to Figure 1-7 , A usage method of a transition section connection device at the junction of a tunnel subgrade and a highway subgrade:

[0039] S1. According to the lengths of the protection plate 3 and the light box 4, determine the fixed-point positions of the guiding piles on the ground. The positions are symmetrically distributed on both sides of the roadside of the road-tunnel transition section, with three on each side, and the middle position is on the center line of the road-tunnel transition section. One position is inside the tunnel, and the other position is outside the tunnel. Embed steel bars 71 at the positions, and then formwork and pour concrete outside the embedded steel bars 71 to form a concrete base 7.

[0040] S2. Install the flipping structure 16 on the middle concrete base 7, and then fix the first guiding pile 1 on the middle concrete base 7 with bolts, and fix the second guiding piles 2 on the concrete bases 7 on both sides.

[0041] S3. Install the light box 4 between the first guiding pile 1 and the second guiding pile 2 through the disassembly and assembly structure 6, then install the protection plate 3 above the light box 4, install the cleaning assembly at the rear of the light box 4, install a liquid collecting hopper 8 on the tops of the first guiding pile 1 and the second guiding pile 2, and connect the liquid collecting hopper 8 with a guide plate 9.

[0042] S4. Start the device, and the flipping structure 16 adjusts the angle of the light box 4. When it is daytime, the downlights 51 illuminate the road surface, making the road surface of the road-tunnel transition section brighter and cleaner, and the LED lamp beads 52 are in the off state. When it is night, the downlights 51 are turned off, and the LED lamp beads 52 flash yellow light for warning and guiding. When the dustiness detection sensor monitors that the dust amount outside the lighting assembly 5 is relatively large, the flipping structure 16 drives the light box 4 to flip, and the cleaning assembly cleans the lighting assembly 5.
