Description

TECHNICAL FIELD

[0001] The present application relates to a kind of waste and old tyre ecological retaining wall and its accident alarm system, in particular to a kind of high damping shock absorption anti-collision waste and old tyre ecological retaining wall and its accident alarm system. BACKGROUND

[0002] With the continuous development of traffic facilities, the traffic safety problems of high-risk areas such as curved road sections, tunnel entrances and exits, and bridge piers are increasingly prominent. Traditional rigid retaining walls are usually made of reinforced concrete and other materials. Although they have strong static compression resistance, under dynamic loads such as vehicle and ship impact, these rigid structures often lack sufficient cushioning and energy absorption capacity, leading to serious structural damage and casualties. Moreover, the use of cement, sand and other materials in construction produces a large amount of carbon emissions, which is not conducive to ecological and environmental protection. In addition, rigid structures are prone to cracking, cracking or even collapse under high kinetic energy impact, lacking good anti-collision stability and toughness. In contrast, flexible retaining walls such as metal mesh retaining walls and rubber plate shock absorption devices can better absorb energy at low speed impact, but their durability is poor and they are easily affected by natural environment and deform, making it difficult to maintain stable protective performance for a long time.

[0003] As a material rich in elasticity and toughness, waste and old tyres have great potential in the design of anti-collision facilities such as roads and bridges due to their excellent energy absorption characteristics. The elastic rubber layer and steel wire framework structure of waste and old tyres enable them to effectively absorb and disperse kinetic energy when subjected to large impact loads, thereby reducing the damage to the structure caused by impact. However, existing waste and old tyre retaining walls are mostly used in low stress conditions, and their performance optimization under high kinetic energy impact is still in the preliminary research stage. Especially under high kinetic energy impact load, the energy absorption effect of the tyre retaining wall gradually decreases, and once the impact force exceeds its carrying capacity, the deformation of the retaining wall may not recover effectively, resulting in loss of energy absorption function and reduction of overall carrying capacity, increasing the risk of damage.

[0004] In addition, the current intelligent monitoring system still has some bottlenecks in the application of traffic facilities, such as dependence on fixed power supply, single function and high cost. Existing monitoring equipment can only provide basic impact and location records, lacking the ability of timely warning and remote linkage, leading to delayed response to traffic accidents, significantly increasing the risk of rear-end collisions of subsequent traffic flow, and increasing the difficulty and loss of rescue. SUMMARY

[0005] The present application aims to provide a high damping shock absorption anti-collision waste and old tyre 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 application comprises a plurality of retaining wall units arranged in sequence in the height direction, at least two layers of coupling damping units are arranged in each retaining wall unit, each layer of coupling damping units comprises a plurality of coupling damping structures, a single coupling damping structure comprises a first-stage coupling damping structure, a second-stage coupling damping structure and a third-stage coupling damping structure connected in sequence, the area between the first-stage coupling damping structure and the third-stage coupling damping structure constitutes an impact area, and the impact area is filled with fillers.

[0007] The first-stage coupling damping structure adopts the mode of transverse paving and vertical staggered stacking of waste tires to form a wall body, and the waste tires are filled with ceramsite fillers to form an anti-impact coupling structure, the tires are bound, and the whole is wrapped and reinforced using geogrids, the high-strength ceramsite fillers have the characteristics of light material, high strength, compression resistance, wear resistance, corrosion resistance, shock resistance and impact resistance, after being subjected to a large impact load, the material friction between the ceramsite particles absorbs a large amount of energy, which can greatly reduce the energy transmission process and play a buffering and energy dissipation role. The flexible coupling system composed of waste tires and ceramsite can adjust the thickness and density according to actual application to meet different grades of anti-collision requirements.

[0008] The same side of the waste tire is connected with the second-stage coupling damping structure, the kinetic energy dissipated by the first-stage coupling damping structure is transmitted to the coupling structure composed of springs and medium-strength ceramsite, the springs further dissipate the impact force through their own compression deformation, and the medium-strength ceramsite has compression and crushing resistance and can maintain stable form under moderate impact energy, thereby playing a buffering and energy dissipation role, the second-stage coupling damping structure adopts a spring group paving form in the horizontal direction and is bound with geogrids in the vertical direction.

[0009] The second-stage coupling damping structure adopts a spring damping device, and the other side of the spring damping device is connected with the third-stage coupling damping structure.

[0010] The third-stage coupling damping structure adopts a pair of U-shaped dampers and low-strength ceramsite, and the residual energy transmitted thereto is absorbed by the geometric deformation of the U-shaped dampers and the friction between the ceramsite.

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

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

[0013] The straight rod of the U-shaped fastener extends out of the reserved screw hole on both sides, after the one end of the U-shaped fastener passes through the spring group, the two ends of the U-shaped fastener are connected with the waste tire through the screw, the spring front end circumference is locked by the spiral steel bar, and the screw is screwed out from the inside of the waste tire to the reserved screw hole, so that the rigid connection can make the energy be transmitted to the spring damping structure for further energy dissipation after the impact occurs, and the spring is prevented from slipping and dislocation after deformation, and the subsequent energy dissipation effect is affected.

[0014] The head of the T-shaped fastener is clamped in the spring, the tail is clamped between the outer surfaces of the two U-shaped dampers, and the whole is bound by using a screw through a reserved hole, so that a continuous structure is formed, which can work together to dissipate impact kinetic energy.

[0015] A high-damping shock-absorbing anti-collision waste tire ecological retaining wall accident alarm system, comprising a pressure sensor, an alarm and a solar cell panel, the pressure sensor is embedded in the waste tire and is electrically connected with the alarm placed on the top of the waste tire retaining wall, the alarm is provided with a solar cell panel beside it, and the solar cell panel placed beside it supplies power to the whole detection and early warning system.

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

[0017]

[0018] and respectively represent the initial time and the end time; Pt represents the instantaneous impact pressure value measured by the soil pressure at a certain time; is a time decay coefficient, which is used to weight the recent pressure change, so that the recent pressure change has a greater influence on Pt, and responds to sudden impact accidents in time; is a weight coefficient of pressure change rate, which is used to adjust the influence degree of pressure change rate in the final result, and can flexibly adjust the sensitivity of the system to pressure change; represents the instantaneous change rate of pressure, which is used to capture the rapid change of pressure and identify sudden impact events.

[0019] By comprehensively considering the cumulative effect and change rate of pressure, the system can distinguish between short-time impact pressure and long-time static pressure, can quickly identify abnormal pressure change at the moment of vehicle impact, and can trigger an alarm signal in time to ensure traffic safety. At the same time, the pressure is mainly dominated by the soil pressure in normal times, and the system is in a stable state, which effectively avoids false alarms caused by environmental factors.

[0020] Advantages: The present application has the following advantages:

[0021] 1. By three-stage damping design, the retaining wall can realize stage-by-stage absorption and dissipation of impact energy, greatly improving the impact resistance of the overall structure. The first-stage coupled damping structure utilizes the high elasticity of waste tire materials and the energy absorption effect of high-strength ceramic fillers to form an energy absorption structure. At the moment of impact, the tire rapidly deforms, and the ceramic particles are squeezed and rubbed, converting the impact energy into internal energy and effectively absorbing it. The second-stage coupled damping structure further dissipates the remaining kinetic energy through the elastic deformation of the spring, and the medium-strength ceramic particles between them play a role in friction resistance to avoid excessive stress being directly transmitted to the rear structure. The third-stage coupled damping structure disperses the residual stress again through the plastic deformation of the U-shaped damper, and the stress is transmitted between the low-strength ceramic particles to make the stress on the structure more evenly distributed, 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, and effectively reduces the risk of damage to the wall and surrounding facilities by impact loads, providing reliable protection for engineering safety.

[0022] 2. Using waste tires as retaining wall materials has significant advantages in economy and environmental protection, providing an innovative solution for sustainable development. Waste tires are widely available and cost-effective, and their application in engineering construction can significantly reduce costs, converting difficult-to-degrade waste into valuable building resources and reducing environmental pollution. Their excellent elasticity, durability, and impact resistance meet engineering requirements and improve structural performance.

[0023] 3. The integrated intelligent monitoring system provides real-time state perception and safety protection for the retaining wall, significantly improving the reliability and management efficiency of the overall facility. The system continuously collects data on various physical parameters such as pressure and vibration through sensors placed at key locations within the wall, and uses built-in algorithms to analyze these data in real time. This proactive safety monitoring approach not only helps operators respond quickly to potential risks, but also effectively avoids significant losses caused by delayed handling.

[0024] 4. The alarm system sends warning signals when it receives abnormal signals, which can timely alert vehicles in the blind area behind the curved road, reducing the likelihood of rear-end accidents and effectively improving 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, while in high-risk scenarios, it can increase sensitivity to enhance monitoring effectiveness, thereby optimizing the alarm strategy.

[0025] 5、The application effectively absorbs and alleviates the impact force through the multi-stage damping module design, improves the protective performance of the retaining wall, reduces the risk of secondary accidents caused by vehicle loss of control, and protects personal and property safety. Traditional retaining walls are prone to structural damage or vehicle rebound due to insufficient rigidity. The application weakens the impact force to a controllable range through multiple damping energy dissipation, avoiding vehicle rebound. At the same time, the system reduces the damage of impact to surrounding facilities, reduces potential hazards such as road debris, and provides a safer environment for rescue work. This technology is suitable for highway, bridge and port terminal scenes, providing innovative solutions for traffic and infrastructure safety management;

[0026] 6、Compared with traditional rigid retaining walls, the application uses the backfill soil in the waste tire as a planting substrate, which can effectively support the growth of climbing plants, realize the organic combination of ecological function and engineering structure. The retaining wall not only meets the functional requirements, but also is more beautiful, and can improve the surrounding environmental quality through plant coverage and increase its ecological effect. At the same time, through the natural action of plant roots, the anti-erosion ability of the surface of the retaining wall can also be enhanced, effectively prolonging the service life of the structure. This environmentally friendly, economical, aesthetic and practical design concept fully embodies the development direction of green building technology;

[0027] 7、The ceramic particles have the characteristics of light material, high strength, compression resistance and impact resistance. After being impacted, the material between the ceramic particles is rubbed and the pores are compressed, absorbing a large amount of energy, which can greatly reduce the energy transmission process and play a buffering and energy dissipation role. At the same time, ceramic particles have excellent porosity and water absorption and retention capacity, not only can quickly absorb and store rainwater and irrigation water, but also can lock nutrients near plant roots for slow absorption by plants without easy loss, thereby achieving the dual goals of saving water resources and nutrients. This innovative design provides a good growing environment for plants, even in drought or harsh weather conditions, and can maintain a high greening rate;

[0028] 8、The coupling structure of spring and ceramic particles realizes the dual advantages of joint damping energy dissipation and ecological greening. Compared with backfill sand and gravel soil, ceramic particles are uniform, light and not easy to compact, which can avoid the blockage of small particles in the spring gap, ensure the sensitive response of the spring to external impact, and effectively improve the damping energy dissipation capacity of the system. At the same time, the porous nature of ceramic particles can disperse the impact load when stressed, and work together with the spring to greatly enhance the buffering performance. In terms of ecological greening, ceramic particles have good air permeability and strong water retention, can store rainwater and nutrients, and continuously supply plant growth, unlike ordinary soil which is prone to compaction or seepage into the spring interior causing corrosion. This design not only endows the retaining wall with excellent protective performance, but also realizes the unity of beauty and environmental protection function, which is an innovative design with safety, durability and greenness.

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

[0039] Example 1

[0040] As shown in Figures 1-6 , the high-damping shock absorption and impact prevention waste tire ecological retaining wall of the present embodiment includes a plurality of retaining wall units arranged in sequence along the height direction, and at least two layers of damping units are arranged between the geogrids in each retaining wall unit, and a return baling method is used to keep the retaining wall stable, as Figures 2-3The damping unit of each layer comprises a plurality of damping structures, and the damping structures in each retaining wall unit are arranged by transverse paving and vertical staggered stacking. A single damping structure comprises a first-stage coupling damping structure, a second-stage coupling damping structure and a third-stage coupling damping structure connected in sequence, the area between the first-stage coupling damping structure and the third-stage coupling damping structure constitutes an impact area, and the remaining area is a non-impact area, which is filled with backfill materials such as soil and gravel, and the high weight can ensure the overall stability of the retaining wall. The third-stage damping structure of the impact area can buffer and dissipate the impact energy, and the ceramsite filler filled in the third-stage damping structure can further dissipate the impact kinetic energy, prevent the soil behind the retaining wall from being disturbed by excessive kinetic energy, and reduce the impact force of the reaction car, thereby achieving the effect of bidirectional soil protection. The ceramsite filler has the characteristics of light material, high strength, pressure resistance, wear resistance, corrosion resistance, shock resistance, etc. After being subjected to a large impact load, the ceramsite particles are broken and the material between the ceramsite particles is rubbed, thereby absorbing a large amount of energy, greatly reducing the energy transmission process, and playing a buffering and energy dissipation role.

[0041] The first-stage damping structure is formed by transverse paving and vertical staggered stacking of waste tires 101 to constitute the main body of the wall, and the first-stage coupling damping structure is formed by filling the waste tires 101 with high-strength ceramsite 102 fillers (particle size greater than 30 mm) having high compactness, low porosity, light weight, high strength and a compressive strength greater than 15 MPa. After being subjected to a vehicle impact load, the tire deforms by its own material properties, the ceramsite particles between the ceramsite particles are rubbed, and the porosity is reduced, thereby dispersing the impact pressure and dissipating a part of the energy generated by the impact; the same side of the waste tire 101 is connected with a second-stage coupling damping structure, the second-stage coupling damping structure uses a spring damping device 201 and medium-strength ceramsite 202 fillers (particle size of 5-15 mm) having a compressive strength of 5-15 MPa, and the kinetic energy dissipated by the first-stage coupling damping structure is transmitted to the coupling structure of the spring and the ceramsite, the spring is compressed and deformed by its own compression, and the ceramsite is compressed and displaced by its void, thereby further dissipating the impact force; the other side of the spring damping device 201 is connected with a third-stage coupling damping structure, the third-stage coupling damping structure uses a pair of U-shaped dampers 301 and low-strength ceramsite 302 fillers (particle size less than 5 mm) having a compressive strength less than 5 MPa, and the residual energy transmitted thereto is absorbed by the geometric deformation of the U-shaped dampers 301 and the friction of the ceramsite. The waste tire 101, the spring damping device 201 and the U-shaped damper 301 are coaxially arranged.

[0042] As Figures 3-6As shown, the spring damping device 201 includes a spring group, the two sides of one end of the spring group are connected with the waste tire 101 through the U-shaped buckle 5, the other end is connected with the U-shaped damper 301 through the T-shaped buckle 6, after the one end 501 of the U-shaped buckle 5 is passed through the spring damping device 201, the two ends of the U-shaped buckle 5 are connected through the screw hole 502 by the screw 503, the U-shaped buckle 5 locks the spiral steel bars on the two sides of the front end of the spring, the screw is screwed out from the inside of the waste tire 101 to the reserved screw hole. This rigid connection can make the energy transmitted to the spring damping structure for further energy dissipation after the impact occurs, and prevent the spring from slipping and dislocation after deformation, affecting the subsequent energy dissipation effect. The head 601 of the T-shaped buckle 6 is clamped in the spring to limit its displacement, and the tail 602 is clamped between the outer surfaces of the two U-shaped dampers 301, and the whole is bound by the screw 604 through the reserved hole 603 to form a continuous structure that can work together to dissipate impact kinetic energy.

[0043] The embodiment takes waste tires as the basic structural units, constructs the wall body through the horizontal paving and vertical staggered stacking, and the waste tire body can effectively absorb the kinetic energy generated in the impact process due to its high elasticity and strong toughness. The tire material (usually a rubber composite) can disperse external force impact through its own deformation, convert concentrated load into relatively uniform stress distribution, thereby reducing the direct damage risk to the retaining wall body. At the same time, the filled ceramsite is a light, porous inorganic particle material with good buffering performance and compression resistance. When the impact occurs, the fine ceramsite has strong compactness, low porosity and good structural integrity, which can effectively disperse the impact energy; the medium ceramsite has a certain sliding and rolling space between particles, and its own friction can effectively disperse the medium-intensity impact energy; the coarse ceramsite has a large gap between particles and can be broken, which can effectively absorb the impact energy. This double-layer energy absorption mechanism makes the combination of waste tires and ceramsite form a cooperative damping system, which greatly improves the impact resistance of the overall structure. The energy absorption 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 application to meet different levels of anti-collision requirements.

[0044] The spring, as a secondary damper, is fixed to the wall surface of the waste tire through a designed U-shaped buckle, ensuring 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 slowly releases it, thereby reducing the instantaneous impact on the structure. This gradual energy release helps 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 accurately designed according to actual needs to adapt to different types and intensities of impact loads. By adjusting the size and installation method of the spring, the response speed and energy absorption capacity of the anti-collision system can be effectively adjusted, enabling the system to cope with variable external impact environments. In addition, the spring has good recovery ability and can quickly rebound to its original position after being hit, maintaining the continuous stability of the structure. Moreover, the spring material has strong durability, low maintenance cost, and simple installation, and only needs to be regularly checked for its elasticity and structural integrity during maintenance. Its low price maintains the economic efficiency of construction cost.

[0045] The U-shaped dampers are connected to each other through T-shaped buckle tails and bolts, and the heads of the T-shaped buckles are buckled at the rear ends of the spring damping devices, restricting the position of the spring and preventing it from slipping and dislocating after being hit by impact loads. The U-shaped dampers produce plastic deformation under stress, further absorbing the remaining energy. The U-shaped structure can work continuously during multiple impact processes, providing a more 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. Moreover, the structure can be reused without frequent replacement, greatly reducing maintenance costs during long-term operation. The structure is relatively simple, allowing for quick installation during construction and adapting to different size and shape design requirements of the anti-collision wall.

[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 embedded in the inner surface of the waste tire 101 and electrically connected to the buzzer alarm 8 placed on the top of the waste tire retaining wall through wires at the appropriate position. The solar panel 9 placed beside it powers the entire detection and early warning system.

[0048] The pressure sensor is connected to the data acquisition module, and the pressure data is transmitted to the data processing unit through wireless communication. The data processing unit uses an embedded micro control chip to receive and analyze 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 two parts of an audible and visual alarm device and a remote communication module, wherein the audible and visual alarm device sends a strong sound signal through the buzzer to remind the surrounding personnel, and the remote communication module sends the alarm information to the data collection terminal through the GSM / 4G network to realize remote monitoring and timely response. , as follows:

[0050]

[0051] wherein, and represent the initial time and the end time, respectively; represents the instantaneous impact pressure value measured by the soil pressure gauge at a certain time; is a time decay 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 the sudden impact accident in time; is a weight coefficient of the pressure change rate, which is used to adjust the influence degree of the pressure change rate in the final result, and can flexibly adjust the sensitivity of the system to the pressure change; represents the instantaneous change rate of the pressure, which is used to capture the rapid change of the pressure and identify the sudden impact event.

[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 and converts it into a digital signal transmitted to the data processing unit. The data processing unit analyzes the pressure data and compares it with the preset threshold. Once an abnormal pressure is found, the system immediately starts the alarm output unit to send an on-site alarm through the audible and visual alarm device, and pushes the alarm information to the user terminal. In addition, the system is powered by a solar photovoltaic panel to ensure all-weather working capability. The present application integrates solar power supply, pressure sensing and intelligent analysis technology, not only realizes independent operation, but also has the characteristics of high efficiency, precision and environmental protection, and can be widely applied in the fields of traffic facilities, industrial production, construction engineering, etc., to improve the public safety level and reduce the operating cost.

[0053] The application can effectively improve the energy absorption capacity of the wall under the impact of dynamic load such as vehicles and ships, reduce the damage of the impact to the structure, ensure the stability and safety, and reduce the damage caused by the reaction force to the vehicles and ships. The pressure-sensitive alarm device powered by solar energy realizes data transmission and early warning function, and can also realize real-time monitoring and accident alarm without external power supply, reduces the risk of rear-end collision caused by unclearness of the front accident, improves the management efficiency of traffic facilities, and reduces the maintenance cost. The climbing plants planted can decorate the retaining wall more ecologically and beautifully.
