Description

Technical Field

[0001] The invention relates to the technical field of ecological greening slope protection, and in particular to an ecological greening slope protection at a tunnel opening which can effectively prevent water and soil loss. Background Art

[0002] The construction of tunnel portals often involves large-scale excavation and disturbance of the ground surface. This disturbance will destroy the original soil structure and vegetation cover, resulting in loose surface soil and long exposure time. In seasons and regions with heavy rainfall or strong winds, this exposed soil is extremely susceptible to water scouring and wind erosion, thus causing soil erosion. In addition, the construction of tunnel portals usually requires the clearing of vegetation near the portals in order to carry out excavation and support operations. The destruction of vegetation reduces the surface cover, reduces the soil's ability to retain water, and makes the soil more susceptible to external erosion. At the same time, the lack of vegetation also weakens the soil's self-repair ability and aggravates the degree of soil erosion.

[0003] In the hilly areas of the south, most highways are built through hills. For the sake of aesthetics and to protect the soil slopes on both sides of the road, vegetation will be planted on the slopes. Ecological slope protection technology will be used to consolidate the soil on both sides of the road to prevent soil erosion and the loss and waste of natural environmental resources. In order to reduce the impact of rain erosion on the slopes, the existing ecological slope protection technology will use protective measures such as green plants to reduce the erosion of the slopes.

[0004] However, after laying cement support on the slope of the tunnel entrance, it takes time for green grass to grow. Once heavy rain occurs during its growth, the planted seeds will be washed away with soil by the heavy rain, resulting in the failure of normal greening planting. Manual replanting is required afterwards, which increases manpower and material resources, delays the normal growth of greening, and is not conducive to the protection of the slope. In addition, when facing rainfall, there is a lack of timely acquisition of rainwater and rainfall, so it is impossible to take corresponding plans to deal with the problems of rainwater erosion and soil erosion. Summary of the invention

[0005] In order to solve the technical problem raised in the background technology that green plants and soil are easily washed away in an environment with heavy rain at the tunnel entrance, which is not conducive to the rooting and growth of green plants and increases the protection cost, the present invention provides an ecological greening slope protection for the tunnel entrance which can effectively prevent soil erosion.

[0048] The bottom end of the rain shield 22 moves in the collecting tube 23 , and the inner collecting tube 23 is fixed to the inner wall of the planting shell 3 . A volute spring is arranged in the collecting tube 23 .

[0049] Bottom flow openings 7 are evenly opened on both sides of the bottom of the frame 5, and the bottom flow openings 7 are connected to the sponge 12. Baffles 30 are symmetrically fixedly connected to the opening of the frame 5, and the baffles 30 seal the water storage mechanism.

[0050] The top of the frame 5 is connected to a top cover 6 in a relatively horizontal sliding manner, and the top of the top cover 6 is fixedly connected to a rack plate 29, and the top of the rack plate 29 is meshingly connected to a gear 6 27, and the gear 6 27 is rotatably connected to a sleeve plate 28, and the sleeve plate 28 is fixedly connected to the inner wall of the planting shell 3.

[0051] The top of gear six 27 is meshedly connected with gear five 26 , and the middle of gear five 26 is fixedly connected with rotating rod one 18 .

[0052] The water storage mechanism is symmetrically arranged on the inner wall of the planting shell 3, including bevel blocks 11 symmetrically inclined inwardly arranged, two groups of bevel blocks 11 are symmetrically fixedly connected with sponges 12 on the upper ends, the tops of the two groups of sponges 12 are both abutted with movable blocks 13, and the tops of the two groups of movable blocks 13 are both fixedly connected with rack plates 15, and the two groups of rack plates 15 are connected to the transmission assembly.

[0053] The detection mechanism includes a displacement sensor and a signal receiving and sending module arranged in the implant shell. The displacement sensor is used to detect the displacement of the movable block 13 in the implant shell and transmit it to the terminal through the signal receiving and sending module. A mounting hole is provided on the sponge 12, and the displacement sensor can be installed on the bottom surface of the movable block 13 through the mounting hole. The displacement sensor adopts an existing ultrasonic ranging sensor, so as to obtain the displacement of the movable block 13 by detecting the distance from the bottom surface of the inner wall of the implant shell 3.

[0054] The implementation principle of an ecological greening slope protection at a tunnel entrance that can effectively prevent soil erosion in the embodiment of the present application is as follows:

[0055] First, the slope of the tunnel entrance is trimmed, the cement slope 1 is fixed and limited by anchor rods 2, and then the planting shell 3 is gradually and orderly installed. After the installation is completed, the soil is filled on the spot and green plant seeds are placed at the connection between the frame 5 and the slope.

[0056] When it rains, when the rainfall is normal, since the planting shell 3 is inclined, water can be stored in the planting shell 3. When the water volume is higher than the bottom of the outer wall water outlet 10, it will automatically flow out and be discharged using the side water outlet 8, the bottom water outlet 9 and the outer wall water outlet 10. When the rainfall increases, the water volume cannot be discharged in time and will cause erosion risks to the soil and seeds in the frame 5. Water will continue to be stored in the planting shell 3, and when the internal water level continues to increase, it will drive the two groups of movable blocks 13 to slide vertically upward along the vertical rod 14; as the relative vertical displacement of the movable block 13 and the vertical rod 14 changes, the displacement sensor installed on the bottom surface of the movable block 13 adopts the existing ultrasonic ranging sensor, so as to obtain the displacement of the movable block 13 by detecting its distance from the bottom surface of the inner wall of the planting shell 3, so as to measure the rainfall and send the data to the terminal in time.

[0057] At the same time, the rack plate 15 will be meshed with the gear 16, and the movable block 13 which is continuously floating will drive the gear 16 to drive the gear 2 17 to rotate, and then the gear 2 17 will be meshed with the gear 3 19 to drive the gear 4 20 to rotate synchronously, and then the gear 4 20 will be meshed with the rain shield 22 to push the rain shield 22 to slide outwards relatively horizontally by two sets of telescopic rods 24, and the rain shield 22 will be extracted from the collection tube 23, and the top of the planting shell 3 will be blocked, so that the amount of water entering the planting shell 3 can be controlled. And as the rain shield 22 moves, the rain shield 22 can be vibrated by the action of the spring inside the spring tube 25, so that the water can be discharged.

[0058] As the rotating rod 18 rotates, the gear 5 26 will be driven to rotate. The gear 5 26 is meshed with the gear 6 27, which can drive the gear 6 27 to drive the rack plate 2 29 to slide outward and block the top of the frame 5 to prevent water, soil and seeds from being washed out.

[0059] When the rainfall decreases, water will gradually penetrate into the connection between the frame 5 and the slope, and the movable block 13 will gradually descend, so that the top cover 6 and the rain shield 22 will return to their original positions.

[0060] Embodiment 2:

[0061] Combination Figure 4-Figure 6 Based on Example 1, this embodiment is further improved in that:

[0062] Vertical rods 14 are symmetrically fixedly connected to both sides of the inner wall of the planting shell 3, and the vertical rods 14 are vertically slidably connected to the movable block 13.

[0063] The two groups of movable blocks 13 are sprayed with hydrophobic material so that when water enters, the entire movable block 13 can be driven to float vertically along the vertical rod 14.

[0064] The implementation principle of an ecological greening slope protection at a tunnel entrance that can effectively prevent soil erosion in the embodiment of the present application is as follows:

[0065] When it rains, since the planting shell 3 is inclined, the rainfall will be temporarily stored in the sponge 12, and the excess water will flow into the slope through the bottom flow port 7. When the rainfall decreases, as the movable block 13 continues to descend, the sponge 12 will be pressed down under the action of gravity, so that the water in the sponge 12 slowly enters the planting soil area in the frame 5, thereby providing water for the seeds to grow.

[0066] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
