Description

Technical Field

[0001] The invention relates to the field of slope protection devices, and in particular to a high fill roadbed slope protection device. Background Art

[0002] The high fill roadbed should be constructed by layered filling and layered compaction, and the thickness of each layer is determined by the filler used. If the filler comes from different sources and has very different properties, it should not be filled in sections or longitudinal sections. Considering that common diseases of high fill roadbeds include overall or partial subsidence of the roadbed, longitudinal cracking of the roadbed, roadbed sliding or slope collapse, the slope is more dangerous, and the slope collapse will cause the entire section of the road to be closed for renovation, thereby increasing the cost of later repairs and maintenance. Therefore, when constructing a high fill roadbed, it is necessary to comprehensively consider the protection of the slope.

[0003] Generally speaking, when traditional slope protection devices are used for protection, they are mostly directly erected by concrete protection blocks or directly pulling protection nets. Among them, the erection of concrete protection blocks requires the middle part to be leaked out, so that part of the soil is exposed, which is convenient for water absorption and drainage, but this will cause soil erosion, and in the long run it will lead to soil desertification, which will cause looseness and make the concrete protection blocks easy to separate; and the method of directly pulling the protection net has the problem of too large an area for pulling the protection net, and at the same time, the connection between the edges of the two protection nets is prone to deformation or detachment. In addition, there is also the problem of rust when pulling the protection net over a large area. After rusting, the replacement needs to cut the entangled protection net, and the protective function of the cut protection net is reduced, so a large area needs to be replaced, which is very inconvenient. Finally, the existing slope protection structure is easily trampled by animals and pedestrians. Even if warning signs are posted, such problems cannot be avoided. Long-term trampling will cause damage to the slope protection structure and lead to separation, which is easy to induce slope collapse and pose a safety hazard. Summary of the invention

[0028] In the present invention, the protective base frame 1 is a square hollow frame, which is assembled to form a protective base plate 4 for mounting other structures. The ground nails 5 are used as mounting parts for mounting the protective base frame 1 on the ground of the high fill slope, and are evenly distributed at the four corners of the lower surface of the protective base frame 1, so as to ensure that the protective base frame 1 is subjected to uniform forces in all directions during use. The anti-pedal plate 7 is installed on each protective base frame 1 of the entire foundation row, so as to prevent wild animals or people from walking and stepping on the protective base frame 1. The planting plate 8 is used to plant beautifying plants on the protective base frame 1. On the one hand, it improves the aesthetics of the slope protection structure. On the other hand, it can also prevent soil erosion by allowing the roots of the beautifying plants to penetrate into the high fill slope, thereby avoiding soil desertification and increasing the stability of the high fill slope.

Since the first rectangular card block 101 and the second rectangular card block 102 are located at two adjacent sides of the protective base frame 1, the opposite sides of the first rectangular card block 101 and the second rectangular card block 102 are both rectangular card slots 103, so that multiple protective base frames 1 are connected to form a separate basic column. The second rectangular card block 102 is located on the left or right side. At this time, two adjacent basic columns are plugged into each other through the second rectangular card block 102 and another rectangular card slot 103, thereby forming a complete protective substrate 4 as a whole, achieving the purpose of rapid assembly.

[0038] In this embodiment, a detailed structure of a planting plate 8 is provided. Specifically, the U-shaped plate 801 is connected to the protective base frame 1 by connecting the wing plate 802 with the opening facing the protective base frame 1. The U-shaped plate 801 is provided with a mounting tube 803 that penetrates the plate body, so as to serve as a positioning tube for beautifying plants. After the roots of the beautifying plants are vertically passed through the mounting tube 803, the root system thereof is passed through the mesh plate 3, so that the root system thereof can be smoothly implanted into the high fill slope, making the protective base frame 1 planted with the beautifying plants more neat and beautiful as a whole.

[0039] As a preferred embodiment, the planting plate 8 includes a plurality of U-shaped plates 801 with openings downward, and connecting wing plates 802 extend from the open ends of the U-shaped plates 801 to both sides, and the connecting wing plates 802 are provided with tension connection holes, and the U-shaped plates 801 are fixedly connected to the protective base frame 1 by connecting bolts; it also includes a plurality of top plate mounting tubes 803 that penetrate the top of the U-shaped plates 801, and the mounting tubes 803 are hollow cylinders; it also includes a fixing tube 804 placed in the mounting tube 803, and the fixing tube 804 is a cylinder with an open top and a closed bottom, and a placement ring 805 extends outward from the top, and a through hole for plants to pass through is opened at the center of the bottom.

[0040] In this embodiment, if Figure 5 As shown, another detailed structure of the planting board 8 is provided, wherein the installation cylinder 803 is no longer used alone as a positioning structure for beautifying plants, but acts as a positioning component for beautifying plants through an additional fixed cylinder 804, and the fixed cylinder 804 is used to be inserted into the installation cylinder 803. By inserting the beautifying plants in advance during transportation and passing through the fixed cylinder 804, the beautifying plants are distributed in advance, and after the planting board 8 is installed, the fixed cylinder 804 and the installation cylinder 803 are quickly plugged in one by one to achieve rapid positioning of the beautifying plants, avoiding damage to the beautifying plants caused by inserting the beautifying plants into the planting board 8 in advance and then transporting them. In addition, gel substances or liquid storage substances such as cotton and sponges with nutrient solution can also be filled into the fixed cylinder 804 to reduce the loss of beautifying plants during transportation.

[0041] As a further embodiment, the inner wall of the installation tube 803 and the outer wall of the fixing tube 804 are provided with matching wave patterns.

[0042] In this embodiment, by providing the wave pattern, the fixing tube 804 is prevented from rotating due to external reasons after being inserted into the installation tube 803, thereby avoiding damage to the stems of the beautifying plants.

[0043] As a preferred embodiment, a circular plug-in tube 104 is provided at each of the four corners below the protective base frame 1. The plug-in tube 104 is provided with a first plug-in hole 105 that horizontally penetrates the side wall. The top of the ground nail 5 is provided with a horizontal through hole that matches the first plug-in hole 105. The ground nail 5 is locked with the plug-in tube 104 by a first plug-in bolt 106.

[0044] In this embodiment, if Figure 6 As shown, a detailed installation method of the ground nail 5 is provided, wherein the plug-in cylinder 104 is arranged at the four corners below the protective base frame 1, thereby ensuring that the force on the single protective base frame 1 is uniform, and the plug-in cylinder 104 and the ground nail 5 are plugged and matched with each other, and the first plug-in bolt 106 that horizontally penetrates the plug-in cylinder 104 and the top of the ground nail 5 is used to realize the quick and detachable connection between the ground nail 5 and the protective base plate 1, thereby facilitating the separate transportation, reducing the floor space occupied during the transportation process, and improving the space utilization rate during the transportation process. In addition, the mechanical connection by plugging can also effectively ensure the connection strength between the ground nail 5 and the single protective base frame 1, thereby effectively preventing the protective base plate 4 from slipping off from the high fill slope as a whole.

[0045] As a further embodiment, Figure 7 As shown, the outside of the ground nail 5 is also provided with a plurality of fixing rings 501, and the outer wall of the fixing ring 501 is provided with barbs 502; the ground nail 5 is also provided with a plurality of second plug holes 503, and the second plug bolts 504 penetrate the fixing ring 501 and the second plug holes 503 to fix the fixing ring 501 to the ground nail 5.

[0046] In this embodiment, a detailed structure of a ground nail 5 is provided, wherein a fixing ring 501 is sleeved on the outside of the ground nail 5, and by adjusting the position of the fixing ring 501, the depth of the barbs 502 on the outer wall of the fixing ring 501 in the soil layer of the high fill slope can be adjusted according to the actual soil conditions of the high fill slope, thereby providing better pull-out resistance and preventing the ground nail 5 from slipping out.

[0047] In addition, the mesh plate 3 includes a first mesh plate 301 and a second mesh plate 302. The mesh size of the first mesh plate 301 is smaller than the mesh size of the second mesh plate 302. The first mesh plate 301 is arranged in the first installation groove 2 of the protective base frame 1 where the anti-pedal plate 7 is located, and the second mesh plate 302 is arranged in the first installation groove 2 of the protective base frame 1 where the planting plate 8 is located.

[0048] By dividing the mesh plate 3 into two types with different mesh sizes, it is possible to facilitate the plant roots in the planting plate 8 to quickly pass through the second mesh plate 302 with a larger size, while not affecting the blocking effect of the first mesh plate 301 with a smaller mesh size on the high fill slope soil layer, further avoiding the occurrence of slope collapse. In order to achieve the above effect, the mesh plate 3 can be selected from prefabricated metal / plastic mesh plates with different mesh sizes, or a mesh plate woven by a drawstring, and the drawstring material is preferably selected from a wear-resistant and corrosion-resistant material to extend the life of the mesh plate 3.

[0049] A third plug hole 303 is provided on the mesh plate 3, and a positioning hole matching the third plug hole 303 is provided on the bottom wall of the first mounting groove 2. The third plug bolt 304 passes through the third plug hole 303 and is screwed into the positioning hole, thereby realizing rapid fixation of the mesh plate 3 and a single mounting substrate 1, and also facilitating rapid replacement of the mesh plate 3 during later maintenance, thereby simplifying the maintenance process and reducing the workload of maintenance operations.
