Technical Field
[0001] This utility model relates to the field of slope greening and protection technology, specifically a slope greening and protection structure. Background Technology
[0002] Steep rock slopes are commonly found in mountainous areas, along roads, in quarries, and in mining areas. Due to their steepness and thin soil layers, these slopes are not only susceptible to weathering and water erosion, leading to rockfalls and slope instability, but their exposed surfaces also hinder direct vegetation restoration, further accelerating soil erosion and slope degradation. With increasing awareness of ecological protection and rising landscape demands, slope greening not only plays a role in preventing soil erosion, conserving water and soil, and improving the ecosystem, but is also a crucial measure for optimizing the environment and enhancing the living landscape.
[0003] Conventional slope greening techniques, such as soil covering and grass planting, anchored plant nets, and eco-bags, while achieving the goal of slope greening to some extent, still have many shortcomings for steep rock slopes with complex terrain and difficult soil covering. These traditional methods include high maintenance difficulty, low survival rate, and limited root growth. Furthermore, long-term wind and rain erosion can threaten slope stability, posing safety hazards to nearby residential areas or transportation facilities. Therefore, how to achieve efficient, environmentally friendly, and sustainable greening of steep rock slopes while ensuring slope structural stability has become a technical challenge that researchers and engineers need to solve.
[0004] Currently, while some scholars have proposed combining reinforcement and greening techniques to achieve the dual goals of slope stability and aesthetics, and other technologies have addressed several issues in traditional greening methods by creating special structural channels to directly connect plant roots with the soil, these solutions still fail to adequately resolve problems encountered in greening steep rock slopes, such as slow vegetation growth, poor root-based soil stabilization, and high maintenance costs. Further innovative greening technologies are needed. Therefore, developing a new type of greening facility for steep rock slopes is particularly urgent and necessary to effectively solve the difficulties and instability of slope covering and to achieve long-term slope stability and aesthetic enhancement. Thus, this paper proposes a slope greening and protection structure. Utility Model Content

A pressure plate and a ground nail are provided above the fourth galvanized iron wire. The bottom end of the ground nail slides through the top surface of the pressure plate and the top surface of the slope, extending into the interior of the slope.
[0009] Preferably, the irrigation assembly includes an irrigation pipe and a capillary tube located above the slope. The bottom end face of the irrigation pipe outlet is fixedly installed with the top end face of the capillary tube.

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example 1: Please refer to Figure 1 - Figure 5 This utility model provides a technical solution: a slope greening and protection structure, including a slope 1, with a protection component 30 and an irrigation component 31 installed on the top of the slope 1;
[0025] The irrigation component 31 is located above the protective component 30.
[0026] The protective component 30 includes a first galvanized iron wire 301, a second galvanized iron wire 302, a third galvanized iron wire 303, and a fourth galvanized iron wire 304 located above the slope 1. The first galvanized iron wire 301 and the second galvanized iron wire 302 are arranged in a specific pattern on the slope 1. The third galvanized iron wire 303 and the fourth galvanized iron wire 304 are staggered above the first galvanized iron wire 301 and the second galvanized iron wire 302. The intersection points of the first galvanized iron wire 301, the second galvanized iron wire 302, the third galvanized iron wire 303, and the fourth galvanized iron wire 304 are tightly twisted with double-stranded binding wire. A pressure plate 305 and a ground nail 306 are provided above the fourth galvanized iron wire 304. The bottom end of the ground nail 306 slides through the top surface of the pressure plate 305 and... The top surface of slope 1 extends into the interior of slope 1. Through the protective component 330, a grid structure formed by the first galvanized iron wire 301, the second galvanized iron wire 302, the third galvanized iron wire 303, and the fourth galvanized iron wire 304 reduces the maintenance needs of slope 1 caused by wind and rain erosion. The fixing method of the pressure plate 305 and the ground nail 306 effectively enhances the stability of slope 1 and prevents rock collapse and slope instability. At the same time, the use of planting bags 307 makes vegetation restoration more direct and efficient. The substrate mixed with garden soil in the planting bags 307 provides a good soil environment for vegetation growth. Thus, not only is the stability of slope 1 achieved, but the ecological and landscape value of the slope is also enhanced through the planting of vegetation.
[0027] A planting bag 307 is provided between the third galvanized iron wire 303 and the fourth galvanized iron wire 304. A binding wire 309 is fixedly connected to the surface of the planting bag 307. The binding wire 309 is hung on the surface of the third galvanized iron wire 303 to facilitate the fixing of the planting bag 307.
[0028] Planting bags 307 are made of non-woven fabric and have a tie 308 at the opening. The opening of the planting bag 307 is tied tightly with the tie 308. The use of planting bags 307 makes vegetation restoration more direct and efficient. The growth of vegetation in planting bags 307 helps to improve the soil environment and reduce soil erosion. At the same time, the green vegetation also provides a good visual landscape for the surrounding area.
[0029] The first galvanized iron wire 301 and the second galvanized iron wire 302 each have 20cm protruding at both ends, which are used for inter-block splicing and binding.
[0030] Planting bags 307 contain a substrate mix of garden soil and seeds. The substrate mix ratio is organic fertilizer: perlite: superphosphate = 1:0.5:0.2:0.3 (by volume). When filling, compact the soil to 10cm from the bag opening, then place the bag upright and water thoroughly. After the substrate settles, continue filling until the bag is 10cm from the opening. Soak the seeds in warm water with a fungicide for 24 hours, then drain. Place 2 seeds of *Cassia tora* in the four central holes, 5-8 seeds of *Dianthus altissima* in the four corner holes, and 8-10 seeds of *Cynodon dactylon* in the remaining holes. Sow the *Cassia tora* seeds 3-4cm deep and the other seeds 1-2cm deep.

The bottom end of the outlet pipe of irrigation pipe 312 is fixedly installed with the top end of capillary tube 311. The bottom end of capillary tube 311 is inserted into planting bag 307 from the bag opening. Irrigation pipe 312 is laid on the top surface of slope 1. A bypass pipe 313 is provided on the front side of irrigation pipe 312. The end face of bypass pipe 313 is fixedly inserted through the surface of irrigation pipe 312 and extends into the interior of irrigation pipe 312. A valve is provided inside bypass pipe 313. The bottom end of capillary tube 311 contacts the substrate-mixed garden soil. Through irrigation component 31, the capillary tube 311 and bypass pipe 313 ensure that the vegetation can obtain water evenly and fully, thereby improving the survival rate and growth rate of vegetation. Moreover, the irrigation process is more automated and controllable, reducing labor costs.
[0032] When using, straighten the φ4.0 (8#) first galvanized iron wire 301, second galvanized iron wire 302, third galvanized iron wire 303 and fourth galvanized iron wire 304. First, arrange the first galvanized iron wire 301 and the second galvanized iron wire 302 with a horizontal and vertical spacing of 230cm*230cm on a flat ground. Tighten the interlacing points with double strands of wire to form a single 230cm*230cm grid. Arrange the third galvanized iron wire 303 and the fourth galvanized iron wire 304 with the upper end 1420 as a reference distance of 46cm downwards and to the right. Tighten the interlacing points with double strands of wire. Tap and pull the middle frame to adjust it into a uniform single 46cm*46cm grid. The two ends of the first galvanized iron wire 301 and the second galvanized iron wire 304 each protrude 20cm for inter-block splicing and binding.
[0033] Mix the substrate ratio of garden soil: organic fertilizer: perlite: superphosphate = 1:0.5:0.2:0.3 (by volume) thoroughly. When filling the planting bag (307), compact the garden soil mixture until it is 10cm from the opening. Place the bag upright and water thoroughly. After the soil settles, continue filling until it is 10cm from the opening. Cut a 160cm section of 4*9 fine capillary tube (311) as designed. Insert one end of the capillary tube into the bag, with the other end in contact with the substrate. Tie the opening of the planting bag (307) tightly with a strap (308), leaving the other end of the capillary tube protruding outside the bag. Secure the planting bag (307) with a binding wire (3). 09. Hang the bags vertically between the grids, with a distance of 2cm between the bags and between the bags and the wire; lay the entire facility flat on a level ground and cut 20.5cm wide and 2.5cm x 2.5cm wide holes on the top surface of the bags. Soak the plant seeds in warm water with a chemical agent for 24 hours and drain the water; select the four middle holes and insert 2 seeds of *Cassia tora* per hole, insert 5-8 seeds of *Caragana korshinskii* per hole at the four corners, and insert 8-10 seeds of *Cynodon dactylon* per hole in the remaining holes. The sowing depth is 3-4cm for *Cassia tora* seeds and 1-2cm for the remaining seeds; and use ground nails 306 and pressure plates 305 to fix the protective component 30 to the slope 1.
[0034] Water is introduced through irrigation pipe 312, and the outlet pipe of irrigation pipe 312 is connected to capillary pipe 311. When the valve is opened, part of the water from irrigation pipe 312 is sprayed onto the surface of planting bag 307 through bypass pipe 313. Capillary pipe 311 irrigates the inside of planting bag 307, ensuring that the upper and lower non-woven bags are evenly irrigated. The outside is reinforced with woven hemp rope net (not shown in the figure) to ensure the stability of the greening facility and to reinforce the slope. Based on the irrigation intensity requirements of light loam soil, field water holding capacity, wilting coefficient, and the maximum water flow rate of the pipeline pressure and irrigation water loss coefficient of 0.85, the irrigation volume is designed to be 2394L / h, irrigation duration is 2h / d, and the interval is 5d / time. The irrigation volume per bag is 1.086L / d, and the expected irrigation depth inside the bag is 34.12cm.
