Description

Technical Field

[0001] This utility model relates to the field of road slope protection technology, specifically to a slope protection device based on waste tires for preventing geological disasters. Background Technology

[0002] In recent years, geological disasters have occurred frequently due to both natural and human factors. Landslides, debris flows, and other disasters have caused severe damage to transportation routes, residential areas, and infrastructure. Against this backdrop, the importance of slope protection engineering has become increasingly prominent. Slope protection devices can effectively prevent soil erosion and collapse on slopes and are one of the key measures to reduce losses from geological disasters.

[0003] Traditional slope protection materials mainly include concrete and stone. While concrete slope protection has high strength, its construction cost is high, and its rigid structure is prone to cracking when faced with mountain deformation, thus losing its protective effect. Stone slope protection requires a large amount of manpower and resources for transportation and stacking, and its stability is also affected by factors such as the shape, size, and arrangement of the stones. With the rapid development of the automotive industry, the generation of waste tires has increased dramatically. If large quantities of waste tires are not properly utilized, they will occupy significant land resources, and the natural degradation process of waste tires is very slow, potentially posing safety hazards such as fires.

[0004] Therefore, there is an urgent need for a technology to replace existing slope protection methods in order to solve the problem of how to effectively utilize waste tires for slope protection. Utility Model Content

[0005] In view of this, this utility model proposes a slope protection device based on waste tires for preventing geological disasters, aiming to solve the problem of how to effectively utilize waste tires for slope protection.

[0006] On the one hand, this utility model provides a slope protection device based on waste tires to prevent geological disasters. The slope protection device is attached to one side of a traditional slope and is composed of multiple layers of protective layers. The protective layers are arranged from top to bottom as a first protective layer, a second protective layer and a third protective layer, and the multiple protective layers are fixedly connected to each other.

[0007] The first and second protective layers are used to resist the erosion of water flow, and the third protective layer is provided with a geogrid, inside which waste tires are placed.

[0008] Each layer of the protective layer is filled with filler material between the waste tires and the waste tires.

[0009] Furthermore, in the slope protection device for preventing geological disasters using waste tires, the first protective layer is covered with a layer of waste tire stress netting, which is composed of multiple waste tire stress strips joined together, and the waste tire stress strips are composed of multiple waste tires joined together laterally in sequence.

[0010] The second protective layer is provided with multiple layers of the waste tire stress mesh, and the multiple layers of waste tire stress mesh are fixedly connected.

[0011] Furthermore, in the slope protection device for preventing geological disasters using waste tires, the third protective layer of waste tires is closely arranged and partially buried underground to form a stable base layer.

[0012] Furthermore, in the slope protection device for preventing geological disasters using waste tires, the waste tires in the third protective layer are larger than those in the first and second protective layers, and the filling material inside is concrete and gravel.

[0013] Furthermore, in the slope protection device for preventing geological disasters using waste tires, parallel steel strands are inserted into each waste tire, and after stress is applied to the steel strands, both ends are fixed to the outer edges of the outermost tires at both ends.

[0014] Furthermore, in the slope protection device for preventing geological disasters using waste tires, each end of the steel strand is provided with a fixing pad, the fixing pad matching the outer surface of the worn-out tire, and the fixing pad simultaneously fixing two adjacent steel strands.

[0015] Furthermore, in the slope protection device for preventing geological disasters using waste tires, bolts are fixed at both ends of the steel strand, and the bolts and nuts cooperate to fix the steel strand to the fixing pad on the outermost edge of the tire.

[0016] Furthermore, in the slope protection device for preventing geological disasters using waste tires, springs are installed inside the waste tires in the first and second protective layers.

[0017] Furthermore, in the slope protection device for preventing geological disasters using waste tires, the first protective layer is filled with soil and organic fertilizer, which is used to plant various plants on the tires and in the gaps between the tires; the second protective layer is filled with concrete, or filled with stone, or one or more of mud and sand.

[0018] Furthermore, in the slope protection device for preventing geological disasters using waste tires, geotextile is also laid between each of the protective layers.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] (1) Waste tires have good elasticity and toughness. When the slope is subjected to external forces such as rainwater erosion and earthquakes, and the soil undergoes a certain degree of displacement or minor collapse, the tires can act as a buffer to absorb and disperse energy.

[0021] (2) The outer surface and internal structure of the tire can effectively resist the erosion of the slope by rainwater. Its ring structure can change the runoff path of rainwater on the slope and slow down the flow rate of rainwater. The space inside the tire can store a certain amount of rainwater, preventing rainwater from accumulating in a large amount in a short period of time and causing the slope soil to loosen.

[0022] (3) Waste tires are widely available and can usually be obtained at a low cost through recycling channels. Compared with traditional slope protection materials such as concrete and stone, waste tires are almost a "turn waste into treasure" resource, which greatly reduces the material cost of slope protection devices.

[0023] (4) The installation of waste tire slope protection device is relatively simple. It is lightweight and easy to transport and operate on site. Unlike stone slope protection, it does not require the use of large mechanical equipment for handling and stacking. The installation process has relatively low technical requirements for construction personnel, thereby reducing labor costs. Attached Figure Description

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0032] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0033] See Figure 1 As shown, this embodiment provides a slope protection device for preventing geological disasters based on waste tires. The slope protection device is attached to one side of a traditional slope and is composed of multiple protective layers stacked together. The protective layers are, from top to bottom, a first protective layer 100, a second protective layer 200, and a third protective layer 300. The multiple protective layers are fixedly connected to each other.

[0034] The first protective layer 100 and the second protective layer 200 are used to resist the erosion of water flow. The third protective layer 300 is provided with a geogrid 310, and waste tires are placed inside the geogrid 310.

[0035] Each protective layer is filled with filler material between the inside and between the waste tires.

[0036] Specifically, the used tires are arranged in different layers. At the bottom layer of the slope protection, the tires are tightly packed and partially buried underground to form a stable base layer. This layer uses larger-sized used tires, and the inside of the tires can be filled with gravel or concrete to increase weight and stability. The tires in the middle layer can be arranged in a staggered manner, so that the gaps between the tires intersect, which can better prevent soil erosion from the slope.

[0037] Understandably, this layered design allows the tires to fully utilize their function at different levels. The third protective layer 300 provides stable support, while the second protective layer 200 prevents soil erosion. Furthermore, the layered design can be flexibly adjusted according to the specific requirements of the slope protection and environmental conditions, such as thickening the intermediate layer in areas prone to soil erosion.

[0038] See Figure 2 As shown, the slope protection device for preventing geological disasters using waste tires has a first protective layer 100, which is covered with a layer of waste tire stress netting. The waste tire stress netting is composed of multiple waste tire stress strips joined together, and the waste tire stress strips are composed of multiple waste tires joined together laterally in sequence.

[0039] The second protective layer 200 is covered with multiple layers of waste tire stress mesh, which are fixedly connected.

[0040] Specifically, in environments such as rivers and coastal slopes, waste tire stress netting can effectively resist the erosion of water flow and waves. When water impacts the slope, the stress netting distributes the impact force to each tire. The tires interact with each other and transmit the force through the connecting steel strands 201, enabling the entire structure to stably resist the erosion of the water flow. In riverbank protection projects, this stress netting can act as a flexible shield, reducing the erosion of the slope by river water and preventing riverbank collapse.

[0041] Understandably, for slopes with soft soil or steep gradients, waste tire stress netting can increase slope stability. This is achieved through interaction with the slope soil. On one hand, the weight of the stress netting can exert pressure on the slope soil, inhibiting the soil's tendency to slide; on the other hand, the connecting steel strands 201 between the tires can penetrate deep into the slope soil, generating friction with soil particles and restraining their movement.

[0042] Specifically, the slope protection device for preventing geological disasters using waste tires consists of a third protective layer of 300 waste tires closely arranged and partially buried underground, forming a stable base layer.

[0043] Specifically, the slope protection device for preventing geological disasters using waste tires has a third protective layer 300 made of worn-out tires that is larger than the first protective layer 100 and the second protective layer 200. The internal filling material is concrete and gravel.

[0044] See Figure 3 As shown, the slope protection device for preventing geological disasters using waste tires has parallel steel strands 201 inserted into each waste tire. After stress is applied to the steel strands 201, both ends are fixed to the outermost edges of the tires at both ends.

[0045] Specifically, in the slope protection device for preventing geological disasters using waste tires, the two ends of the steel strand 201 are respectively equipped with fixing pads. The fixing pads match the outer surface of the worn tires, and the fixing pads fix two adjacent steel strands 201 at the same time.

[0046] Specifically, in the slope protection device for preventing geological disasters using waste tires, bolts are fixed at both ends of the steel strand 201, and the bolts and nuts 202 cooperate to fix the steel strand 201 to the fixing pad on the outermost edge of the tire.

[0047] Understandably, steel strand 201 can connect multiple used tires into a single unit. By connecting the used tires together with steel strand 201, these tires form a chain-like structure. In the event of a geological disaster, this connection method can prevent individual tires from being washed away or displaced, thus ensuring that the slope protection device functions as a whole and effectively resists the damage to the slope caused by geological disasters. Moreover, steel strand 201 can be connected to fixed structures on the slope (such as anchor bolts). The anchor bolts are driven deep into stable rock layers, and steel strand 201 connects the used tire slope protection device to the anchor bolts, like adding "anchor points" to the slope protection device, making the slope protection device more firmly fixed to the slope and enhancing the stability of the entire slope protection system.

[0048] Specifically, in the slope protection device for preventing geological disasters using waste tires, springs 110 are installed inside the waste tires in the first protective layer 100 and the second protective layer 200.

[0049] Specifically, spring 110 makes the connection between tires tighter and more elastic. On a slope, when multiple tires equipped with spring 110 are connected or stacked, the spring 110 provides an elastic support force between the tires. This support force helps the tires maintain their position on the slope better, making them less prone to displacement due to external forces. When the soil experiences lateral pressure due to rainwater infiltration, the spring 110 inside the tire can balance this pressure through its own elastic deformation, making the slope protection structure more stable and reducing the possibility of slope collapse.

[0050] Understandably, when a slope is damaged to a certain extent, tires with springs 110 can help restore the original structure of the slope. The elasticity of springs 110 can allow displaced tires to return to their original positions to some extent, and can also readjust the arrangement of the tires. For example, after a small mudslide, a slope protection system with tires containing springs 110 can utilize the elasticity of the springs 110 to reassemble the tires scattered by the mudslide, partially restoring the protective function of the slope and reducing the amount of subsequent repair work.

[0051] Specifically, the slope protection device for preventing geological disasters using waste tires has a first protective layer 100 filled with soil and organic fertilizer, which is used to plant various plants on the tires and in the gaps between the tires; the second protective layer 200 is filled with concrete, or filled with stone, or one or more of mud and sand.

[0052] Understandably, in slope protection devices using waste tires to prevent geological disasters, the filling with soil and organic fertilizer provides an excellent substrate for plant growth. The soil provides space for plant roots to attach and grow, while the organic fertilizer provides the nutrients needed for plant growth, such as nitrogen, phosphorus, and potassium. Planting herbaceous plants within the waste tires of the slope protection device allows their roots to penetrate deep into the filling soil, absorbing nutrients from the decomposed organic fertilizer and thriving.

[0053] These favorable plant growth conditions facilitate the rapid formation of vegetation cover. Vegetation cover plays a vital role in preventing geological disasters. It reduces the direct erosion of slopes by rainwater, intercepts rainwater through plant branches and leaves, and slows down the speed and flow of slope runoff. Furthermore, the root system of vegetation can form a network structure in the soil, enhancing the soil's shear strength, further stabilizing the slope, and preventing geological disasters such as landslides.

[0054] Specifically, the slope protection device for preventing geological disasters using waste tires also has geotextile 210 laid between each protective layer.

[0055] Specifically, in slope protection devices using waste tires to prevent geological disasters, geotextile 210 plays a good filtering role. When rainwater or slope runoff flows through the slope protection device, geotextile 210 allows water to pass through smoothly while preventing soil particles from being carried away by the water flow. Geotextile 210 also has a drainage function, guiding infiltrated rainwater to appropriate drainage channels. This helps maintain the soil moisture balance within the slope protection device, preventing geological disasters such as landslides caused by excessive water accumulation leading to increased soil weight and reduced shear strength.

[0056] Understandably, the laying of geotextile 210 can enhance the integrity between the waste tire slope protection device and the slope surface. It can improve the friction and adhesion between the two through interaction with the slope soil and the slope protection device.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
