Description

Technical Field

[0001] This application relates to the field of slope greening technology in agriculture and forestry, and in particular to a quick-change module for greening rock slopes, as well as an installation method. Background Technology

[0002] Rock slope greening is a new and effective ecological slope protection method that protects exposed slopes. Combined with traditional engineering slope protection, it effectively restores the ecological vegetation on slopes. In some road construction projects and fixed building construction, exposed slopes, especially rock slopes, left after earthwork excavation require slope greening to restore and protect ecological vegetation. Common rock slope greening techniques include bag-stacking, netting and direct spraying of nutrient materials, and topsoil planting. However, these methods are susceptible to erosion by rainwater, easily washing away vegetation, have low drought resistance, and result in poor greening effects.

[0003] In the prior art, the Chinese invention patent with the authorization announcement date of February 24, 2023, authorization announcement number CN113812283B, and titled "A Greening and Vegetation System for Rock Slopes," discloses a grid frame fixed on the slope, in which each grid of the grid frame forms a filling area for filling planting material. The planting material filled in the filling area is a flexible foam material, and plant seeds are covered below the surface of the flexible foam material.

[0004] The aforementioned technology has the advantages of structural stability and strong water and fertilizer retention, but the overall survival rate of planting depends closely on the soft foam material, making the survival rate uncontrollable, and the later maintenance and replacement costs are high. Summary of the Invention

[0005] Through research, the inventors discovered that existing methods for greening rock slopes often suffer from problems such as poor contact between the substrate and the slope surface, leading to growth difficulties, and uneven vegetation cover, which is not conducive to the fixation of the gridded soil. These problems are likely to result in short survival time of vegetation on rock slopes, long ecological restoration cycles, and consequently high maintenance costs.

[0006] The purpose of this application is to provide a quick-change module and installation method for greening rock slopes. By using an integrated planting method and a targeted fixing method based on rock slopes, it solves the technical problem that existing technologies cannot improve the survival rate of green plants while reducing the maintenance cost of rock slopes.

[0007] According to one aspect of this application, a quick-change module and installation method for greening rock slopes are provided, including a flexible planting component. The flexible planting component includes a receiving cavity, a substrate filling cavity, and a soil cavity. The upper and lower ends of the substrate filling cavity flexibly abut against the receiving cavity. The soil cavity flexibly abuts against the substrate filling cavity. The receiving cavity includes at least one set of first storage cavities for seed storage and at least one set of second storage cavities for nutrient solution storage.

[0008] In some embodiments, the end of the soil cavity away from the flexible abutment of the substrate filling cavity is rotatably connected to a fixing component.

[0009] In some embodiments, the fixing assembly includes a rotating joint and a fixing pile rotatably connected to the rotating joint.

[0010] In some embodiments, the fixed pile forms an angle α with the bottom surface of the soil cavity, wherein the value of α is: 0°≤α<90°.

[0011] In some embodiments, the soil cavity is a telescopic cavity.

[0012] In some embodiments, the substrate filling cavity is filled with a soil conditioner, a water-retaining agent, an anti-erosion agent, and water.

[0013] In some embodiments, a perforation is provided on the outer periphery of the first storage cavity, and the diameter of the perforation is smaller than the particle size of the seeds placed inside the perforation.

[0014] In some embodiments, the second storage cavity is filled with a mixed slurry, which is composed of *Diploca spp.*, *Tetralopithecus spp.*, *Spirulina platensis*, and deionized water.

[0015] In some embodiments, the walls of both the first storage cavity and the second storage cavity are made of plastic film.

[0016] According to another aspect of this application, a method for installing quick-change modules for greening rock slopes is provided, comprising the following methods:

[0017] Step 1. Pre-drill mounting holes in the rock slope;

[0018] Step 2. Press the fixing component into the mounting hole;

[0019] Step 3. Press the accommodating cavity and the substrate filling cavity into the soil cavity;

[0020] Step 4. Adjust the angle between the fixed pile and the bottom face of the soil cavity so that the soil cavity comes into contact with the rock slope.

[0021] In summary, this application achieves one-time and rapid planting of vegetation on rock slopes by pressing the accommodating cavity and the substrate filling cavity in the flexible planting component, effectively differentiating it from the step-by-step processing of existing technologies. At the same time, this application incorporates fixing piles and rotating joints to adapt to the adjustment of the rock slope angle, increasing the tightness of the substrate and the rock slope surface, and overcoming the problem of high replacement and maintenance costs and low survival rate of vegetation caused by the existing technology of fixing plants on a single vertical slope surface.

[0030] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0031] This embodiment provides a quick-change module and installation method for greening rock slopes. Both the quick-change module and installation method are currently in the testing and application phase for small-scale rock slope protection. The following description, in conjunction with the attached... Figure 1-4 Describe them together.

[0032] Example 1

[0033] This embodiment provides a quick-change module for greening rock slopes, including a flexible planting component 2. The flexible planting component 2 includes a receiving cavity 21, a substrate filling cavity 22, and a soil cavity 23. It should be noted that the flexible planting component 2 in this embodiment is integrally compressible; that is, the receiving cavity 21 and the substrate filling cavity 22 are compressible. During operation, with the help of external force from construction personnel, the receiving cavity 21 and the substrate filling cavity 22 are pressed together into the soil cavity 23, forming the structure as described in the attached diagram. Figure 2 The state shown.

[0034] Furthermore, the upper and lower ends of the substrate filling cavity 22 flexibly abut against the receiving cavity 21, and the soil cavity 23 flexibly abuts against the substrate filling cavity 22. The receiving cavity 21 includes at least one set of first storage cavities 211 for seed storage and at least one set of second storage cavities 212 for culture medium storage. Specifically, the upper and lower ends of the substrate filling cavity 22 flexibly abut against the receiving cavity 21. During operation, the substrate filling cavity 22 will be pressed along with the receiving cavity 21 when it is pressed by external forces. Furthermore, when the substrate filling cavity 22 deforms under external pressure, it further compresses the receiving cavity 21 at the lower end of the substrate filling cavity 22, ultimately pressing all of the aforementioned materials into the soil cavity 23, forming an attached... Figure 2 The state shown is as described. It should also be noted that in this embodiment, the substrate is mixed by pressing it into the soil, rather than by direct mixing. The intuitive result is that the pressed substrate is more deeply mixed into the soil.

[0035] Furthermore, the substrate filling cavity 22 is filled with soil conditioner, water-retaining agent, anti-erosion agent, and water. It should be noted that the preparation process of the soil conditioner is as follows:

[0036] Step 1. Add polylactic acid to sodium hydroxide solution and stir. After stirring, add sodium citrate and stir again. Then add anhydrous ethanol and stir. Let stand and dry to obtain intermediate product M.

[0037] Step 2. Add magnesium chloride, copper sulfate, and barium hypochlorite to deionized water and stir until homogeneous. Add the mixture to intermediate product M obtained in Step 1, add ammonia water dropwise, react at a constant temperature, cool, centrifuge, wash, and dry to obtain intermediate product N.

[0038] Step 3. Mix chitosan and acetic acid solution evenly to obtain chitosan solution. Add ferulic acid to chitosan solution and continue the reaction. After drying, obtain intermediate product O.

[0039] Step 4. Add intermediate product N obtained in step 2 and intermediate product O obtained in step 3 to deionized water, stir, and then dry to obtain soil conditioner.

[0040] Furthermore, the first storage chamber 211 has perforations on its outer periphery, the diameter of which is smaller than the particle size of the seeds placed inside. The second storage chamber 212 is filled with a mixed slurry composed of *Dictyophora indicum*, *Tetralopithecus obliquus*, *Spirulina platensis*, and deionized water. The walls of both the first and second storage chambers 211 and 212 are made of plastic film. Specifically, in this embodiment, perforations are provided on the outer periphery of the first storage chamber 211, the diameter of which is smaller than the particle size of the seeds placed inside, to ensure that the seeds do not fall out on their own after being placed inside. Next, the second storage chamber 212 is filled with the mixed slurry so that, under subsequent external pressure, the seeds can mix with the mixed slurry, achieving seed pretreatment, unlike existing technologies that require a separate step, thus avoiding process complexity.

[0041] Meanwhile, the accommodating cavity 21 is set at both the upper and lower ends of the substrate filling cavity 22 in order to increase the vegetation coverage in the later stage and improve the overall soil fixation effect. In the prior art, in order to improve the soil fixation effect, an external grid paving is used for fixation, but it does not improve the vegetation coverage rate. The reason is that the grid paving is fixed by external force, which has many influencing factors. In this embodiment, the soil fixation treatment is based on the density of natural vegetation growth. Within a unit area, the higher the vegetation coverage rate, the better the soil fixation effect and the higher the vegetation survival rate.

[0042] Example 2

[0043] The technical features in this embodiment are basically the same as those described in Embodiment 1. The same technical features and solutions will not be repeated here; only the differences between Embodiment 2 and Embodiment 1 will be described. A fixing component 3 is rotatably connected to the end of the soil cavity 23 away from the flexible abutment substrate filling cavity 22. The fixing component 3 includes a rotating joint 24 and a fixing pile 25 rotatably connected to the rotating joint 24. The fixing pile 25 forms an angle α with the bottom surface of the soil cavity 23, with a value of 0°≤α<90°. Specifically, setting an angle between the fixing pile 25 and the bottom surface of the soil cavity 23 allows the quick-change module of this embodiment to be more stably fixed on the rock slope. In the prior art, fixing is done perpendicular to the slope surface. Although this is convenient, over time, due to the gravity effect of increased vegetation, gaps form between the bottom of the vegetation planting and the slope surface, preventing close contact and ultimately leading to growth difficulties and affecting the survival rate of the vegetation. Furthermore, due to stress, the subsequent maintenance costs will also increase. In this embodiment, an angled fixing method is adopted, which can effectively decompose the gravity after the vegetation is added, reduce the probability of gaps, improve the tightness of the vegetation planting bottom and the slope surface, and ultimately improve the survival rate of vegetation on the rock slope.

[0044] Example 3

[0045] The technical features in this embodiment are basically the same as those described in Embodiment 2. The same technical features and solutions will not be repeated here; only the differences between Embodiment 2 and Embodiment 3 will be described. The soil cavity 23 is a telescopic cavity. Specifically, in this embodiment, the soil cavity 23 is telescopic in order to encompass the accommodating cavity 21, making its overall structure appear attached... Figure 2 The state shown.

[0046] Example 4

[0047] The technical features in this embodiment are basically the same as those described in Embodiment 1. The identical technical features and solutions will not be repeated here; only the differences between Embodiment 4 and Embodiment 1 will be described. (Reference) Figure 5 Because of the differences in the shape of the rock slope and the environment, the flexible planting component 2 can be set vertically, which can also achieve the same vegetation coverage and survival rate.

[0048] To verify the vegetation survival rate of the aforementioned method, the inventors conducted experimental planting on rock slopes in a specific area, and obtained the results shown in Table 1 below:

[0049]

[0050] Table 1 Comparison of Plant Survival Rates

[0051] As shown in Table 1 above, the quick-change module of this embodiment can significantly improve the survival rate of green plants.

The installation method includes: Step 1. Pre-drilling installation holes in the rock slope 1; Step 2. Pressing the fixing component 3 into the installation holes; Step 3. Pressing the receiving cavity 21 and the substrate filling cavity 22 into the soil cavity 23; Step 4. Adjusting the angle between the fixing pile 25 and the bottom end face of the soil cavity 23 so that the soil cavity 23 is in full contact with the rock slope surface.

[0053] The foregoing has shown and described the basic principles, main features, and advantages of this application. It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or basic characteristics of this application.
