Description

Technical Field

[0001] The present invention relates to the field of slope protection, and particularly to a protection system based on the linkage of a flexible protection net and an airbag. Background Art

[0002] With the frequent occurrence of global climate change and extreme weather events, the risk of geological disasters is increasing day by day. Especially during the construction of infrastructure such as mountain roads, railways, and urban buildings, the excavation and reinforcement of slopes are inevitable. However, natural factors such as rain erosion and weathering can easily cause the loosening of slope rock and soil, which in turn leads to geological disasters such as rockfalls and landslides, posing a serious threat to human activities and the safety of infrastructure.

[0003] Traditional protection methods, such as retaining walls, concrete reinforcement and installation, etc., although effective to a certain extent, also have some deficiencies and limitations. For example, the construction of retaining walls is difficult, costly, and it is difficult to adapt to slope deformation; the cost of concrete reinforcement and installation is high, the construction period is long, and the impact on the environment is relatively large. The traditional protection system is relatively passive, and the cost is high, and the buffering effect on large-scale rockfalls is limited. In recent years, with the acceleration of the urbanization process and the rapid development of transportation infrastructure construction, protection technologies have been widely applied in the fields of highways, railways, and buildings. Traditional flexible protection nets are woven from metal wire ropes or steel wire ropes, with a certain degree of elasticity and impact resistance, and can effectively prevent rockfalls and soil erosion. However, these protection nets have deficiencies such as being unable to give real-time warnings and having limited buffering effects on large-scale rockfalls, and it is difficult to meet the high requirements of modern transportation infrastructure for safety and reliability. With the rapid development of transportation infrastructure, especially the large-scale construction of highways and other important transportation routes, the stability of the roadbed is directly related to traffic safety and the protection of people's lives and property. Therefore, it is imperative to further upgrade and optimize the protection net technology. In response to this demand, the present invention proposes a protection system based on the linkage of a flexible protection net and an airbag, which combines a flexible protection net, an airbag, and waste tires to create a comprehensive protection system that can not only effectively intercept rockfalls but also have a passive buffering impact ability. This innovative system significantly improves the comprehensive performance of the protection net and can provide real-time response and efficient protection in a wider range of application scenarios. Summary of the Invention

[0004] In view of the above problems, a protection system based on the linkage of a flexible protection net and an airbag is provided, aiming to maximize the performance of the protection system by optimizing the structure and cost.

[0005] The specific technical solutions are as follows: A protection system based on the linkage of a flexible protection net and an airbag, including a protection net, further including a buffer zone arranged in front of the protection net, in which multiple groups of first buffer components for buffering the kinetic energy of falling rocks are arranged. The first buffer components are arranged at intervals along the direction parallel to the foot of the mountain slope, and the upper and lower ends of the protection net are installed behind the buffer zone through buffer reset components.

[0006] Furthermore, the protection system further includes a second buffer component for buffering the kinetic energy of falling rocks, which is installed on the roadbed behind the protection net.

[0007] Furthermore, the first buffer component is formed by stacking waste tires, and the waste tires are filled with sand and gravel.

[0008] Furthermore, adjacent waste tires are tied to each other.

[0009] Furthermore, the buffer reset component includes a mounting seat and a tension reset spring. The mounting seat is correspondingly installed on the roadbed or the ground, and the two ends of the tension reset spring are correspondingly installed on the mounting seat or the protection net.

[0010] Furthermore, the mounting seat is made of damping rubber.

[0011] Furthermore, the protection net includes a protection net frame, an outer protection net and an inner protection net installed on the protection net frame. The outer protection net is made of wire mesh, and the inner protection net is made of rope net.

[0012] Furthermore, the wire mesh is made of zinc aluminum alloy.

[0013] Furthermore, the second buffer component includes an airbag and a sensor. The sensor is installed on the protection net, and the airbag is installed on the roadbed.

[0014] Furthermore, the second buffer component further includes a solar panel, which is installed on the roadbed, and the solar panel is electrically connected to the sensor.

[0015] The beneficial effects of the above solution are as follows: 1. The present invention uses a flexible protection net as the main component of the protection structure, and is assisted by an airbag and waste tires, which not only effectively reduces the accumulation of waste, reduces resource waste and environmental pollution, but also reduces the demand for new materials, thus saving a large amount of resources and costs, conforming to the current advocated concept of green environmental protection and sustainable development, and promoting a virtuous cycle of win-win economic and environmental benefits.

[0016] 2. This invention boasts a simple design, primarily consisting of a flexible protective net, airbags, and a waste tire cushioning device. Its clear structure facilitates on-site assembly. The modular design of the protection system, with components secured by simple connectors, allows for rapid assembly and significantly shortens the construction cycle. Furthermore, the structure possesses excellent toughness and compressive strength, ensuring long-term integrity. Post-maintenance requires only simple inspection and replacement of components, resulting in low maintenance costs and ease of operation, ensuring the long-term stability of the protection system.

[0017] 3. The airbags in this invention are made of high-strength, corrosion-resistant materials with excellent weather resistance and toughness, effectively withstanding wind, sun, and other harsh environmental factors, ensuring long-term stable operation. When subjected to a significant impact, the airbags rapidly inflate, instantly mitigating the impact of falling rocks and dispersing the energy, further protecting the roadbed from impact.

[0018] 4. This invention utilizes a multi-layered protection design, primarily consisting of a buffer zone of scrap tires, a double-layer flexible protective net, and an airbag. The tire buffer zone effectively absorbs and disperses the impact of falling rocks, significantly reducing direct damage to the protective net. The protective net, comprised of a double-layer flexible structure, possesses excellent elasticity and toughness, effectively blocking falling rocks. The airbag rapidly inflates in the event of a significant impact, instantly mitigating the impact and dissipating the energy, minimizing damage to the overall structure. This enhances protection effectiveness and ensures the long-term safety and stability of the roadbed subgrade area.

[0019] 5. The protective structure of this invention features a flexible design that can be adjusted to suit varying terrain and environmental conditions, offering strong adaptability. Whether it's a steep mountain slope or a gentle embankment, the present invention can achieve optimal protection by adjusting the arrangement of the flexible protective net, the number of scrap tires in the buffer zone, and the placement of the airbags. Its modular design allows for flexible assembly and layout during construction, adapting to various slope protection requirements. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0024] The following further illustrates the present invention with reference to the accompanying drawings and specific embodiments, but is not a limitation of the present invention.

[0025] As Figures 1 to 3 shown, the protection system provided in the embodiment of the present invention includes a protective net 10 and a buffer zone 20 arranged in front of the protective net 10. A plurality of first buffer components 30 for buffering the kinetic energy of falling rocks are arranged in the buffer zone 20. The first buffer components 30 are arranged at intervals front and back along the direction parallel to the foot of the hillside. The upper and lower ends of the protective net 10 are installed behind the buffer zone through a buffer reset component 40.

[0026] As Figure 1 shown, in the present invention, when the falling rock 50 rolls down the hillside into the buffer zone 20, the first buffer component 30 buffers the kinetic energy of the falling rock 50 to block part of the falling rocks 50; a small number of falling rocks 50 with greater kinetic energy pass through the buffer zone 50 and are then blocked by the protective net 10. Thus, the first buffer component 30 is used to perform primary buffering on the falling rock 50, reduce the direct impact on the rear protective net 10, and improve the overall blocking effect of the protective net 10 and the service life of the protective net 10.

[0027] Furthermore, to prevent the protective net 10 from failing and the falling rock 50 from damaging the roadbed, as Figure 1 shown, a second buffer component 60 can also be configured on the roadbed behind the protective net 10 in the present invention to form a multi-level protection system by using the second buffer component 60, the protective net 10, and the first buffer component 30.

[0028] As a specific example, as Figure 1As shown, the first buffer component 30 in the present invention can be formed by stacking waste tires. It can be understood that the above stacking forms include but are not limited to being closely arranged in a multi-layer grid form, overlapping alternately horizontally and vertically, "honeycomb" structure, "staggered stacking" structure, staggered arrangement in different sizes and shapes, etc.; the use of the above waste tires can not only effectively utilize the elastic energy of the tires to buffer the kinetic energy of the falling rocks 50, but also effectively reduce the accumulation of waste, reduce resource waste and environmental pollution, and also reduce the demand for new materials, thus saving a large amount of resources and costs, meeting the current advocated concept of green environmental protection and sustainable development, and promoting a virtuous cycle of economic and environmental win-win. To enhance the buffering effect and prevent displacement between the tires, the space between each layer of tires can be filled with filling materials such as sand or gravel; further, to improve the stability of the overall buffer area, adjacent waste tires can also be tied together using iron wires, etc.

[0029] In the present invention, the interval area between the first buffer components 30 in the buffer area 20 can ensure the free drainage of groundwater and can also be used as a reserved space for planting vegetation to ensure the growth of vegetation. The green mesh body is integrated with the natural environment, and artificial greening can be implemented synchronously to achieve the perfect combination of protection and ecological restoration, and reduce the damage of the project to the landform.

[0030] As a specific example, such as Figure 1 、 Figure 2 As shown, the buffer reset component 40 in the present invention includes a mounting seat 41 and a stretching reset spring (which can include a vertical stretching reset spring 44 and multiple groups of oblique stretching reset springs, such as a first oblique stretching reset spring 42 and a second oblique stretching reset spring 43). The mounting seat 41 is correspondingly installed on the roadbed or the ground, and the two ends of the stretching reset spring are correspondingly installed on the mounting seat 41 or the protection net 10; under the above structure, when the falling rock 50 falls into the protection net 10, the stretching reset spring deforms and drags the protection net 10, so as to effectively block the falling rock 50 by using the protection net 10. In the present invention, various types of stretching reset springs can have different elastic coefficients, that is, the vertical stretching reset spring 44, the first oblique stretching reset spring 42, and the second oblique stretching reset spring 43 have different elastic coefficients, so as to adapt to different intensities of impact energy, ensure that the energy can be effectively absorbed and dispersed during the impact of the falling rock, and reduce the impact on the entire protection structure. In the present invention, the mounting seat 41 can be made of damping rubber to further relieve the impact load.

[0031] As a specific example, such as Figure 1 、 Figure 3 As shown, the protection net 10 in the present invention (as shown in Figure 3 a) includes a protection net frame 11, an outer protection net 12 installed on the protection net frame 11 (as shown in Figure 3 b) and an inner protection net 13 (as shown in Figure 3As shown in Fig. c, the inner protective net 13 can be made of a rope net); the outer protective net 12 can be made of a wire net (the wire net is made of a corrosion-resistant material, such as made of zinc-aluminum alloy), and hexagonal honeycomb-shaped mesh holes can be opened on the wire net. The outer protective net 12 can disperse the impact force of the falling rock 50 through its own deformation.

[0032] As a specific example, such as Figure 1 、 Figure 3 As shown, in the present invention, the second buffer assembly 60 includes an airbag 61 and a sensor 62 electrically connected to the airbag 61. The sensor 62 is installed on the protective net 10, and the airbag 61 is installed on the roadbed; the surface layer of the airbag 61 is made of a corrosion-resistant material, which can effectively prevent wind and sun exposure and has strong durability. In the present invention, the sensor 62 can include, but is not limited to, an angle sensor and a displacement sensor. When the falling rock 50 rolls into the protective net 10, the protective net 10 swings greatly to use the sensor 62 to monitor the swing amplitude or swing displacement of the protective net 10. When the swing amplitude or swing displacement is greater than the threshold value, the sensor 62 generates an electrical signal, and the system will automatically activate the airbag to quickly inflate it, so as to provide additional protection for the wall at the bottom of the roadbed. Further, in the present invention, the second buffer assembly 60 can also include a solar panel 63 installed on the roadbed, and the solar panel 63 is electrically connected to the sensor 62 to effectively supply power to the system using solar energy.

[0033] The construction method of the above system in the present invention is as follows: (1) Site cleaning: Comprehensively clean the construction site, remove loose stones and sundries, ensure that the area is flat and there are no obstacles, and provide good basic conditions for subsequent construction.

[0034] (2) Buffer zone layout: Excavate a foundation pit of a certain depth at the bottom of the slope of the site, pour concrete piles, and provide a platform for the installation of waste tires.

[0035] (3) Installation of flexible protective net: Install a double-layer flexible protective net near the roadbed wall.

[0036] (4) Sensor installation: Install sensors on the inner protective net and protect the sensors with special protective cases.

[0037] (5) Installation of airbag: Install an airbag at the bottom of the roadbed retaining wall and provide appropriate protection on the surface layer. And check the contact between the solar charging panel, the sensor and the airbag.

[0038] (6) Laying of tire buffer zone: Lay waste tires in the buffer zone. The tires are arranged closely to act as the first buffer barrier and absorb the initial impact energy of the falling rocks.

[0039] (7) Inspection and debugging: Conduct an inspection of the overall structure, test the stability and energy dissipation effect of the flexible net to ensure that the expected protection standard is achieved.

[0040] (8) Regular inspection and maintenance.

[0041] The above are only the preferred embodiments of the present invention, and do not limit the implementation manners and protection scope of the present invention. For those skilled in the art, it should be realized that all equivalent replacements and obvious changes made by using the description and illustrations of the present invention should be included in the protection scope of the present invention.
