Description

Technical Field

[0001] The invention relates to a waste tire ecological retaining wall and an accident alarm system thereof, in particular to a high-damping shock-absorbing and anti-collision waste tire ecological retaining wall and an accident alarm system thereof. Background Art

[0002] With the continuous development of transportation facilities, traffic safety issues in high-risk areas such as curved road sections, tunnel entrances and exits, and bridge piers are becoming increasingly prominent. Traditional rigid retaining walls usually use materials such as reinforced concrete. Although they have strong static compressive strength, these rigid structures often lack sufficient buffering and energy absorption capacity under dynamic loads such as vehicle and ship collisions, resulting in serious structural damage and casualties. In addition, the cement, sand and gravel and other materials used in their construction will produce a large amount of carbon emissions, which is not conducive to ecological protection. In addition, rigid structures are prone to cracks, cracks, and even overall collapse under high kinetic energy impacts, and lack good anti-collision stability and toughness. In contrast, flexible retaining walls, such as metal mesh retaining walls and rubber plate shock-absorbing devices, can absorb energy well under low-speed impacts, but their durability is poor, and they are easily affected by the natural environment and age and deform, making it difficult to maintain stable protective performance for a long time.

[0003] As a material with high elasticity and toughness, waste tires have excellent energy absorption properties, which makes them have great potential in the anti-collision design of roads, bridges and other facilities. The elastic rubber layer and steel wire skeleton structure of waste tires enable them to effectively absorb and disperse kinetic energy when subjected to large impact loads, thereby reducing the damage to the structure caused by the impact. However, existing waste tire retaining walls are mostly used in low-stress conditions, and their performance optimization in the face of high-kinetic energy impacts is still in the preliminary research stage. Especially under high-kinetic energy impact loads, the energy absorption effect of the tire retaining wall will gradually decay. Once the impact force exceeds its bearing capacity, the deformation of the retaining wall may not be effectively restored, causing it to lose its energy absorption function and reduce its overall bearing capacity, increasing the risk of damage.

[0004] In addition, the current application of intelligent monitoring systems in traffic facilities still has some bottlenecks, such as reliance on fixed power supply, single function and high cost. Existing monitoring equipment can usually only provide basic collision records and location records, lacking the ability of timely warning and remote linkage, resulting in delayed response to traffic accidents, greatly increasing the risk of subsequent traffic rear-end collisions, and increasing the difficulty and loss of rescue. Summary of the invention

[0005] Purpose of the invention: The purpose of the invention is to propose a high-damping shock-absorbing and anti-collision waste tire ecological retaining wall and its accident alarm system to improve the protective performance and stability of the retaining wall under high kinetic energy impact.

[0006] Technical solution: The present invention includes a plurality of retaining wall units arranged in sequence along the height direction, at least two layers of coupling damping units are arranged in each retaining wall unit, each layer of coupling damping units includes a plurality of damping structures, a single coupling damping structure includes a primary coupling damping structure, a secondary coupling damping structure and a tertiary coupling damping structure connected in sequence, the area between the primary coupling damping structure to the tertiary coupling damping structure constitutes an impact area, and the impact area is filled with filler.

[0007] The primary coupling damping structure uses waste tires to form the main body of the wall by horizontal paving and vertical staggered stacking, and fills the waste tires with ceramsite fillers to form an anti-collision coupling structure. The high-strength ceramsite filler has the characteristics of light material, high strength, compression resistance, wear resistance, corrosion resistance, shock resistance, and impact resistance. After being subjected to a large energy impact load, the friction between the ceramsite particles consumes energy and absorbs a large amount of energy, which can greatly reduce the energy transfer process and play a role in buffering and dissipating energy. The flexible coupling system composed of waste tires and ceramsite can adjust the thickness and density according to actual applications to meet different levels of anti-collision requirements.

[0008] The same side of the waste tire is connected with a secondary coupling damping structure. The kinetic energy dissipated by the primary coupling damping structure is transmitted to the coupling structure composed of a spring and medium-strength ceramsite. The spring further dissipates the impact force through its own compression deformation, while the medium-strength ceramsite has compression resistance and crushing capabilities, can maintain a stable shape under moderate impact energy, and plays a role in buffering and energy dissipation.

[0009] The secondary coupling damping structure adopts a spring damping device, and the other side of the spring damping device is connected to the tertiary coupling damping structure.

[0010] The three-stage coupled damping structure adopts U-shaped dampers and low-strength ceramsite arranged in pairs, and the residual energy transmitted thereto is absorbed by the friction between the geometric deformation and the ceramsite.

[0011] The waste tire, the spring damping device and the U-shaped damper are coaxially arranged.

[0012] The spring damping device comprises a spring group, both sides of one end of the spring group are connected to the waste tire through a U-shaped fastener, and the other end of the spring group is connected to the U-shaped damper through a T-shaped fastener.

[0013] After one end of the U-shaped fastener passes through the spring group, the two ends of the U-shaped fastener are connected to the waste tire by screws. The U-shaped fastener locks the spiral steel bars on both sides of the circumference of the front end of the spring, and the screws pass through the inside of the waste tire and are screwed into the reserved screw holes. This rigid connection can enable the energy to be transferred to the spring damping structure for further energy dissipation after an impact occurs, and prevent the spring from slipping and dislocating after deformation, which affects the subsequent energy dissipation effect.

[0014] The head of the T-shaped fastener is stuck inside the spring, and the tail is stuck between the outer surfaces of the two U-shaped dampers, and the whole is bound with screws to form a continuous structure that can work together to dissipate impact kinetic energy.

[0015] The invention discloses an accident alarm system for a high-damping shock-absorbing and anti-collision waste tire ecological retaining wall, comprising a pressure sensor, an alarm and a solar panel. The pressure sensor is buried in the waste tire and is electrically connected to the alarm placed on the top of the waste tire retaining wall. A solar panel is arranged next to the alarm, and the solar panel placed next to the alarm supplies power for the entire detection and early warning system.

[0016] The pressure sensing accident alarm system can reduce sensitivity to reduce false alarms under long-term low-load conditions, and increase sensitivity to enhance monitoring effects in high-risk scenarios. Calculate the cumulative impact pressure value F based on the instantaneous impact pressure-time curve t , the formula is as follows:

[0017]

[0018] t 0 and t n They represent the initial time and the end time respectively; F(t) represents the instantaneous impact pressure value measured by the earth pressure gauge at a certain moment; ω is the time attenuation coefficient, which is used to weight the recent pressure change so that the recent pressure change has a greater impact on Pt and responds to sudden impact accidents in a timely manner; α is the weight coefficient of the pressure change rate, which is used to adjust the influence of the pressure change rate in the final result, and can flexibly adjust the system's sensitivity to pressure changes; Indicates the instantaneous rate of change of pressure, used to capture rapid changes in pressure and identify sudden impact events.

[0019] By comprehensively considering the cumulative effect and change rate of pressure, the system can distinguish short-term impact pressure from long-term static pressure, and can quickly identify abnormal pressure changes at the moment of vehicle collision, trigger alarm signals in time, and ensure traffic safety. At the same time, the pressure is usually dominated by soil pressure, and the system is in a stable state, effectively avoiding false alarms caused by environmental factors.

[0020] Beneficial effects: The present invention has the following advantages:

[0021] 1. Through the three-level damping design, the retaining wall can absorb and dissipate the impact energy in stages, greatly improving the impact resistance of the overall structure. The first-level coupling damping structure uses the high elasticity of waste tire materials and the energy absorption effect of high-strength ceramsite fillers to form an energy-absorbing structure. At the moment of impact, the tires quickly deform and the ceramsites squeeze and rub against each other, converting the impact energy into internal energy and effectively absorbing it; the second-level coupling damping structure further consumes the remaining kinetic energy through the elastic deformation of the spring, and the medium-strength ceramsite filled in between exerts its friction resistance to avoid excessive stress being directly transmitted to the rear structure; the third-level coupling damping structure disperses the residual stress again through the plastic deformation of the U-shaped damper, and the mutual transmission of stress between low-strength ceramsites makes the structure more evenly stressed, so that the impact energy is fully attenuated in the entire system. This multi-level and progressive energy management mechanism significantly improves the anti-collision effect of the retaining wall, optimizes the energy dissipation efficiency, effectively reduces the risk of damage to the wall and surrounding facilities caused by the impact load, and provides reliable protection for engineering safety;

[0022] 2. Using waste tires as retaining wall materials has significant advantages in terms of economy and environmental protection, and provides an innovative solution for sustainable development. Waste tires are widely available and low-cost. Using them in engineering construction can significantly reduce costs, transform difficult-to-degrade waste into valuable construction resources, and reduce environmental pollution. Its excellent elasticity, durability, and impact resistance meet engineering needs and improve structural performance;

[0023] 3. The integrated intelligent monitoring system provides real-time status perception and safety assurance for the retaining wall, significantly improving the reliability and management efficiency of the overall facility. The system can continuously collect data on various physical parameters including pressure and vibration through sensors placed at key locations inside the wall, and use built-in algorithms to analyze these data in real time. This proactive safety monitoring method can not only help operators respond quickly to potential risks, but also effectively avoid significant losses caused by delayed processing;

[0024] 4. The alarm system sends out a warning signal when receiving an abnormal signal, which can promptly alert vehicles in the blind spot behind the curved road, reduce the possibility of rear-end collisions, and effectively improve traffic safety. The system can distinguish between short-term impact pressure and long-term static pressure. Under long-term low-load conditions, the system can reduce sensitivity to reduce false alarms, and increase sensitivity in high-risk scenarios to enhance monitoring effects, thereby optimizing the alarm strategy;

[0025] 5. The present invention uses a multi-stage damping module design to effectively absorb and mitigate impact force, improve the protective performance of retaining walls, reduce the risk of secondary accidents caused by vehicle loss of control, and ensure personal and property safety. Traditional retaining walls are prone to structural damage or vehicle rebound due to insufficient rigidity. The present invention uses multiple damping energy dissipation to weaken the impact force to a controllable range and avoid vehicle rebound. At the same time, the system reduces damage to surrounding facilities caused by the impact, reduces potential dangers such as road debris, and provides a safer environment for rescue work. This technology is suitable for scenes such as highways, bridges, and port terminals, providing innovative solutions for transportation and infrastructure safety management;

[0026] 6. Compared with traditional rigid retaining walls, the present invention uses the backfill soil in waste tires as a planting matrix, which can effectively support the growth of climbing plants and achieve an organic combination of ecological functions and engineering structures. The retaining wall is more beautiful while meeting functional requirements, and can also improve the quality of the surrounding environment through plant coverage, thereby increasing its ecological effect. At the same time, through the natural action of plant roots, the erosion resistance of the retaining wall surface can also be enhanced, effectively extending the service life of the structure. This design concept of environmental protection, economy, beauty and practicality fully reflects the development direction of green building technology;

[0027] 7. Ceramic aggregate is light in weight, high in strength, and resistant to compression and impact. After being subjected to impact loads, the friction between the materials and the compression of the pores of the ceramsite particles absorb a large amount of energy, which can significantly reduce the energy transfer process and play a role in buffering and dissipating energy. At the same time, ceramsite has excellent porosity and water absorption and retention capabilities. It can not only quickly absorb and store rainwater and irrigation water, but also lock nutrients near the plant roots for the plants to absorb slowly without losing them easily, thereby achieving the dual goals of saving water resources and nutrients. This innovative design provides a good growth environment for plants, and can maintain a high greening rate even in drought or harsh climate conditions;

[0028] 8. The coupling structure of spring and ceramsite achieves the dual advantages of combined damping and energy dissipation and ecological greening. Compared with backfill sand and gravel, ceramsite particles are uniform, light and not easy to compact, which can prevent small particles from clogging the spring gap, ensure that the spring responds sensitively to external impact, and effectively improve the damping and energy dissipation capacity of the system. At the same time, the porous characteristics of ceramsite can disperse the impact load when subjected to force, and work together with the spring to greatly enhance the buffering performance. In terms of ecological greening, ceramsite has good air permeability and strong water retention. It can store rainwater and nutrients and continuously supply plant growth without compacting or penetrating into the spring to cause corrosion like ordinary soil. This design not only gives the retaining wall excellent protective performance, but also realizes the unity of aesthetics and environmental protection functions. It is an innovation that combines safety, durability and greenness. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The present invention will be further described below in conjunction with the accompanying drawings.

[0039] Example 1

[0040] like Figure 1 to Figure 6 As shown, the high damping shock-absorbing and anti-collision waste tire ecological retaining wall of this embodiment includes a plurality of retaining wall units arranged in sequence along the height direction, at least two layers of damping units are arranged between the geogrids in each retaining wall unit, and the retaining wall is kept stable by using the back-pack reinforcement method, such as Figures 2-3As shown. Each layer of damping unit includes multiple damping structures, and the damping structures in each retaining wall unit are arranged in a horizontally flattened and vertically staggered stacking manner. A single damping structure includes a first-level coupled damping structure, a second-level coupled damping structure, and a third-level coupled damping structure connected in sequence. The area between the first-level coupled damping structure and the third-level coupled damping structure constitutes the impact area, and the remaining area is the non-impact area. The non-impact area is filled with backfill materials such as soil and sand, and its high weight can ensure the overall stability of the retaining wall. The three-level damping structure in the impact area can buffer and dissipate the impact energy, and fill the three-level damping structure with ceramsite filler to further dissipate the impact kinetic energy, prevent excessive kinetic energy from disturbing the soil behind the retaining wall, and reduce the impact force reacting back to the car, so as to achieve the effect of two-way protection. Ceramic aggregate filler has the characteristics of light material, high strength, compression resistance, wear resistance, corrosion resistance, shock resistance and impact resistance. After being subjected to high-energy impact load, the materials between the ceramsite particles rub and break, absorbing a large amount of energy, which can greatly reduce the energy transfer process and play a role in buffering and dissipating energy.

[0041] The primary damping structure uses waste tires 101 to form the main body of the wall by horizontal paving and vertical staggered stacking, and fills the waste tires 101 with high-strength ceramsite 102 filler (particle size greater than 30mm) with strong density, low porosity, light weight and high strength, and compressive strength greater than 15MPa to form a primary coupling damping structure. After being impacted by the vehicle, the tire deforms through the characteristics of its own material, the friction between the ceramsite particles and the reduction of porosity disperse the impact pressure and consume part of the energy generated by the impact; the same side of the waste tires 101 is connected to the secondary coupling damping structure, and the secondary coupling damping structure uses a spring damping device 201 The kinetic energy of the medium-strength ceramsite 202 filler (particle size of 5 to 15 mm) with a compressive strength between 5 and 15 MPa is transmitted to the coupling structure of the spring and ceramsite after dissipation through the first-stage coupling damping structure. The spring further dissipates the impact force through its own compression deformation, the ceramsite through its gap compression and particle displacement; the other side of the spring damping device 201 is connected to a three-stage coupling damping structure, which uses a U-shaped damper 301 arranged in pairs and a low-strength ceramsite 302 filler (particle size of less than 5 mm) with a compressive strength less than 5 MPa. The residual energy transmitted here is absorbed by its geometric deformation and the friction resistance of the ceramsite. The waste tire 101, the spring damping device 201 and the U-shaped damper 301 are coaxially arranged.

[0042] like Figure 3 to Figure 6As shown, the spring damping device 201 includes a spring group, both sides of one end of the spring group are connected to the waste tire 101 through a U-shaped fastener 5, and the other end is connected to the U-shaped damper 301 through a T-shaped fastener 6. After one end 501 of the U-shaped fastener 5 passes through the spring damping device 201, the two ends of the U-shaped fastener 5 are connected by screws 503 through screw holes 502. The U-shaped fastener 5 locks the spiral steel bars on both sides of the circumference of the front end of the spring, and the screws pass through the inside of the waste tire 101 and are screwed into the reserved screw holes. This rigid connection can enable the energy to be transferred to the spring damping structure for further energy dissipation after the impact occurs, and prevent the spring from slipping and dislocating after deformation, which affects the subsequent energy dissipation effect. The head 601 of the T-shaped fastener 6 is stuck inside the spring to limit its displacement, and the tail 602 is stuck between the outer surfaces of the two U-shaped dampers 301. The whole is bound by screws 604 through the reserved holes 603 to form a continuous structure that can work together to dissipate impact kinetic energy.

[0043] This embodiment uses waste tires as the basic structural unit, and constructs the main body of the wall by horizontal paving and vertical staggered stacking. The waste tire body can effectively absorb the kinetic energy generated during the impact due to its high elasticity and strong toughness. The tire material (usually a rubber compound) can disperse the external force impact through its own deformation, converting the concentrated load into a more uniform stress distribution, thereby reducing the risk of direct damage to the main body of the retaining wall. At the same time, the filled ceramsite is a lightweight, porous inorganic granular material with good buffering performance and compressive resistance. When an impact occurs, the fine-grained ceramsite can effectively disperse the impact energy due to its strong density, low porosity and good structural integrity; the medium-grained ceramsite particles have a certain slip and rolling space, and its own friction can effectively disperse the medium-intensity impact energy; the coarse-grained ceramsite particles have large gaps and can be broken, which can effectively absorb the impact energy. This double-layer energy absorption mechanism allows the combination of waste tires and ceramsite to form a synergistic shock absorption system, which greatly improves the impact resistance of the overall structure. The energy-absorbing layer designed in this way not only has good economic benefits, but also has the characteristics of convenient construction and simple maintenance, and is suitable for various complex terrains and scene requirements. The flexible coupling system composed of waste tires and ceramsite can adjust the thickness and density according to actual applications to meet different levels of collision protection requirements.

[0044] As a secondary damper, the spring is fixed to the wall of waste tires by the designed U-bolts to ensure that the spring will not slip and dislocate after being hit; the spring converts the remaining impact energy into elastic potential energy through elastic deformation and releases it slowly, thereby reducing the instantaneous impact on the structure. This gradual energy release helps to improve the anti-collision effect and reduce the risk of damage to the wall or surrounding facilities. The spring has strong adaptability, and its elastic modulus and stiffness can be precisely designed according to actual needs to adapt to impact loads of different types and intensities; by adjusting the specifications and installation methods of the spring, the response speed and energy absorption capacity of the anti-collision system can be effectively adjusted, so that the system can cope with the changing external impact environment. In addition, the spring also has good recovery ability, and can quickly rebound to its original position after impact to maintain the continuous stability of the structure. In addition, the spring material has strong durability, low maintenance cost, and relatively simple installation. During maintenance, it only needs to regularly check its elasticity and structural integrity. Its low price maintains the economy of construction costs.

[0045] The U-shaped damping structures are connected to each other through the tail of the T-shaped member and the bolts. The head of the T-shaped member is buckled in the rear end of the spring damper to constrain the position of the spring and prevent the spring from slipping and dislocating after being subjected to the impact load. The U-shaped damper produces plastic deformation after being subjected to force due to its unique shape structure, further absorbing the remaining energy. The U-shaped structure can continue to work during multiple impacts, providing a relatively uniform and continuous energy absorption effect. This enables the anti-collision system to better cope with high-intensity, multiple impact events, significantly improving the anti-collision effect. In addition, the structure is reusable and does not require frequent replacement, which greatly reduces the maintenance cost in long-term operation. Its structure is relatively simple, can be quickly installed during construction, and can adapt to the design requirements of anti-collision walls of different sizes and shapes.

[0046] Example 2

[0047] The accident alarm system of this embodiment includes a thin film array pressure sensor 7, a buzzer alarm 8, and a solar panel 9. The thin film array pressure sensor 7 is buried in the inner surface of the waste tire 101, and is electrically connected to the buzzer alarm 8 placed on the top of the waste tire retaining wall at an appropriate position by a wire, and the solar panel 9 placed next to it provides power for the entire detection and warning system.

[0048] The pressure sensor is connected to the data acquisition module and transmits the pressure data to the data processing unit through wireless communication. The data processing unit uses an embedded microcontroller chip to receive and analyze the data from the pressure sensing unit. The system introduces a pressure threshold model to determine whether the current pressure exceeds the set range. When the pressure exceeds the preset threshold, the data processing unit will immediately generate an alarm instruction and record relevant data information.

[0049] The buzzer alarm 8 includes an audible and visual alarm device and a remote communication module. The audible and visual alarm device emits a strong sound signal through a buzzer to alert people around, while the remote communication module sends the alarm information to the data collection terminal through the GSM / 4G network to achieve remote monitoring and timely response. For example, under long-term low-load conditions, the system can reduce sensitivity to reduce false alarms, while in high-risk scenarios, the sensitivity can be increased to enhance the monitoring effect. At the same time, the cumulative impact pressure value F is calculated based on the instantaneous impact pressure-time curve. t , the formula is as follows:

[0050]

[0051] Among them, t 0 and t n They represent the initial time and the end time respectively; f(t) represents the instantaneous impact pressure value measured by the earth pressure gauge at a certain moment; ω is the time attenuation coefficient, which is used to weight the recent pressure change so that the recent pressure change has a greater impact on Pt and responds to sudden impact accidents in a timely manner; α is the weight coefficient of the pressure change rate, which is used to adjust the influence of the pressure change rate in the final result, and can flexibly adjust the system's sensitivity to pressure changes; Indicates the instantaneous rate of change of pressure, used to capture rapid changes in pressure and identify sudden impact events.

[0052] When the target area is subjected to external impact pressure, the sensor in the pressure sensing unit captures the pressure change in real time, converts it into a digital signal and transmits it to the data processing unit. The data processing unit analyzes the pressure data and compares it with the preset threshold. Once abnormal pressure is detected, the system immediately starts the alarm output unit, issues an on-site alarm through the sound and light alarm device, and pushes the alarm information to the user terminal. In addition, the system is continuously powered by solar photovoltaic panels to ensure all-weather working capabilities. By integrating solar power supply, pressure sensing and intelligent analysis technology, the present invention not only realizes independent operation, but also has the characteristics of high efficiency, precision and environmental protection. It can be widely used in transportation facilities, industrial production, construction engineering and other fields to improve public safety and reduce operating costs.

[0053] The present invention can effectively improve the energy absorption capacity of the wall under the impact of dynamic loads such as vehicles and ships, reduce the damage to the structure caused by the impact, ensure its stability and safety, and reduce the damage caused by the reaction force to the vehicle and ship. At the same time, combined with the solar-powered pressure-sensitive alarm device, it can realize data transmission and early warning functions, and can perform real-time monitoring and accident alarm without external power support, reduce the risk of rear-end collision caused by unclear front accidents, improve the management efficiency of traffic facilities, and reduce maintenance costs. Planted climbing plants can embellish retaining walls to make them more ecological and beautiful.
