Description

Technical Field

[0001] The present invention belongs to retaining walls, and particularly relates to a waste tire retaining wall that can be monitored and automatically disassembled and replaced, as well as a construction method thereof. Background Art

[0002] In order to promote the popularization and application of modular waste tire retaining walls, when they are applied in important embankment sections or retaining parts of mountain slopes prone to landslides, it is urgent to propose new engineering technologies on how to timely detect the risk of damage to the tire retaining wall during operation, and how to timely replace and reinforce the dangerous parts. Generally, most of the monitoring technologies for retaining walls require manual on-site data collection at regular intervals, which is labor-intensive and has poor timeliness.

[0003] The traditional structure of tire retaining walls usually relies on stacking whole tires filled with soil, and then drilling holes in the tires and using nylon straps for binding to achieve the connection and positioning between the tires. However, this construction method has significant defects. Firstly, the drilling and binding processes are cumbersome, consuming a large amount of construction time and labor, and the accuracy and precision of drilling are often difficult to guarantee, which directly affects the overall strength and stability of the wall. Secondly, once local damage or deformation occurs in the wall structure, due to the complex connection method between the tires and the difficulty of disassembly, the repair or reinstallation work will become extremely difficult. In terms of monitoring technology, the traditional monitoring of retaining walls mainly relies on manual on-site data collection at regular intervals. This method not only has a large workload but also has poor timeliness, making it difficult to timely capture the small deformations or abnormal conditions of the wall. Although there are various wireless monitoring means on the market currently, such as anchor rods for monitoring deformation and positioning monitors arranged on slopes or rocks, their practicality and durability are poor when applied to important embankment sections or retaining parts of mountain slopes prone to landslides.

[0004] Generally speaking, the existing tire retaining walls have problems such as long construction time, large labor consumption, and difficulty in timely capturing small deformations or abnormalities of the wall. Summary of the Invention

[0005] Object of the Invention: In order to overcome the deficiencies in the prior art, the object of the present invention is to provide a waste tire retaining wall with high monitoring accuracy that can be monitored and automatically disassembled and replaced. Another object of the present invention is to provide a construction method for a waste tire retaining wall that is convenient for construction and can be monitored and automatically disassembled and replaced.

[0006] Technical solution: A waste tire retaining wall that can be monitored and automatically disassembled and replaced according to the present invention includes waste tires, connection components, monitoring devices, and fillers. The waste tires are connected to each other through the connection components. The monitoring devices are arranged on one side of the waste tires close to the soil to be retained, and the waste tires are filled with fillers. The connection components include fixed connection pieces and elastic connection pieces. The fixed connection pieces are connected to the elastic connection pieces, and buckles for fixing the waste tires are arranged on the surfaces of the fixed connection pieces and the elastic connection pieces. Backfill soil is arranged on one side of the waste tires.

[0007] Further, the connection components are integrally formed of nylon composite materials with a thickness of 4 - 6 mm.

[0008] Further, the fixed connection piece includes a first locking key, a first locking hole, a second locking hole, and a drainage port. The first locking key and the first locking hole are on the same side and are respectively used to connect with the first locking hole and the first locking key of the adjacent fixed connection piece. The second locking hole is arranged near and connected to the elastic connection piece, and the drainage port is arranged near the first locking hole.

[0009] Further, a second locking key is arranged at the end of the elastic connection piece, and the second locking key is connected to the second locking hole. The drainage port is connected to a conversion connecting pipe. The conversion connecting pipe is connected to a flexible permeable pipe. The conversion connecting pipe includes a water inlet end and a water outlet end. The water inlet end is connected to the flexible permeable pipe, and the water outlet end is inserted into the drainage port of the fixed connection piece.

[0010] Further, the fixed connection piece is L-shaped, and the elastic connection piece is linear.

[0011] Further, the monitoring device includes a wireless displacement sensor, a data processing module, and a power supply module. The wireless displacement sensor is connected to the data processing module and transmits displacement deformation data to the monitoring platform terminal. The terminal monitoring system analyzes the collected data and issues a reminder for abnormal deformation.

[0012] A construction method of a waste tire retaining wall that can be monitored and automatically disassembled and replaced according to the present invention includes the following steps:

[0013] S1. Install the fixed connection pieces on the waste tires;

[0014] S2. Add fillers to the waste tires to form plug soil tire modules. The waste tires are fixedly connected to each other through the connection components to form a stable retaining wall structure;

[0015] S3. Layer by layer, set up tire panels, and backfill the backfill soil layer by layer. Connect the flexible permeable pipes, fix the monitoring devices in the boxes, and place them on one side of the waste tires close to the soil to be retained;

[0016] S4. Set parameters and conduct technical debugging on the monitoring devices, turn on the monitoring system, and collect and transmit real-time data;

[0017] S5. Evaluate the stability of the retaining wall based on the data received by the terminal monitoring system, and comprehensively consider the on-site conditions to decide whether it is necessary to replace some of the waste tires or to reinforce the local large deformation with concrete; when it is necessary to replace the waste tires, press the first lock key of the waste tire fixing connector and the second lock key of the bouncing connector to be disassembled in turn to unlock them, use a jack and a template to temporarily support the waste tire, replace the new waste tire, lock it, and finally remove the temporary support structure such as the jack.

[0018] Working principle: Waste tires are used as the basic unit of the retaining wall. Through clever stacking and connection, an indestructible wall structure is formed. The connection component is made of nylon composite material as a link between the waste tires. It has excellent strength and toughness, ensuring the tight connection between the waste tires and avoiding loosening and deformation of the retaining wall. The connection component adopts a lock key and lock hole structure, making the connection and disassembly extremely simple. Among them, the connection component includes a fixed connector and a bouncing connector. The fixed connector realizes the stable connection and positioning between the tire modules through the close cooperation of the first lock key and the second lock hole at the bottom of the fixed connector, while the bouncing connector uses its bouncing lock key to connect with the second lock hole at the top of the fixed connector to further enhance the connection strength between the tire modules and prevent the tire from flipping and dislocation. The monitoring device consists of a wireless displacement sensor, a data processing module and a power module, which monitors the displacement and deformation of the retaining wall in real time. The filler, as the filler inside the waste tire, not only increases the weight and stability of the tire, but also improves the anti-slip ability of the retaining wall.

[0019] Beneficial effects: Compared with the prior art, the present invention has the following significant features:

[0020] 1. By using waste tires as the main structural unit of the retaining wall, it not only realizes the reuse of resources and reduces environmental pollution, but also reduces the cost of building materials. It is green and environmentally friendly. The retaining wall has long-term stability and durability and can effectively resist soil sliding and collapse;

[0021] 2. The key and lock hole structure design of the connection components makes the disassembly and replacement of the waste tire retaining wall simple and quick, which not only facilitates the maintenance and upgrading of the project, but also extends the overall service life of the retaining wall;

[0022] 3. The built-in monitoring device can monitor the displacement and deformation of the retaining wall in real time. Through the coordinated work of the wireless displacement sensor, data processing module and power module, rapid data collection, processing and analysis are achieved. This function not only improves the safety performance of the retaining wall, but also can issue early warnings in time when abnormal deformation occurs, providing strong support for engineering maintenance;

[0023] 4. The drain outlet on the fixed connecting piece, the conversion connecting pipe, and the flexible water-permeable pipe together constitute an efficient drainage system, which not only ensures the dryness and stability inside the retaining wall, but also improves the drainage efficiency, effectively preventing water damage to the structure of the retaining wall. The flexibility and water-permeable performance of the flexible water-permeable pipe enable the retaining wall to adapt to various complex geological conditions. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] As Figures 1 - 2, the recyclable waste tire retaining wall that can be monitored and automatically disassembled and replaced includes waste tires 1, connection components 2, monitoring devices 3, and fillers 4. The waste tires 1 are fixedly connected through the connection components 2. The monitoring devices 3 are placed on the side of the waste tires 1 close to the soil mass, and the fillers 4 are filled inside the waste tires 1. The waste tires 1 serve as the main structural units of the retaining wall. A solid barrier is formed through the stacking and connection of the waste tires 1. After backfilling the soil behind the retaining wall on one side, it effectively blocks the sliding and collapse of the soil mass. The connection component 2 with a live opening is integrally formed from a nylon composite material with a thickness of 4 - 6 mm. The connection and disassembly are achieved through a lock key and lock hole structure. The strength and toughness of the connection component 2 ensure the tight connection between the waste tires, avoiding the loosening and deformation of the retaining wall. Moreover, the nylon composite material has good corrosion resistance, wear resistance, and anti-aging properties, extending the service life of the connection component 2 and facilitating disassembly and replacement. The monitoring device 3 consists of a wireless displacement sensor, a data processing module, and a power supply module, and is used to monitor the displacement and deformation of the retaining wall in real time. The displacement and deformation of the retaining wall are monitored through the wireless displacement sensor. The data processing module processes and analyzes the monitoring data, and the power supply module provides power support for the monitoring device. The filler 4 is the material filled inside the waste tire 1, increasing the weight and stability of the waste tire 1 and improving the anti-slip ability of the retaining wall.

[0036] According to the analysis of the rupture surface of the slope, the monitoring equipment in this invention is mainly installed at the bottom of the retaining wall. The stability of the retaining wall can be understood in real time based on the data received by the monitoring system. According to the received data, timely intervention can be carried out on the potential instability of the slope, which can play a very good prevention and control role.

[0037] Such as Figures 3 - 9, the connecting component 2 includes a fixed connecting piece 21 and a bouncing connecting piece 22. The fixed connecting piece 21 is connected to the bouncing connecting piece 22, and buckles 23 are provided on the surfaces of both the fixed connecting piece 21 and the bouncing connecting piece 22. The fixed connecting piece 21 is L-shaped, and the bouncing connecting piece 22 is linear. The fixed connecting piece 21 includes a first locking key 211, a first locking hole 212, a second locking hole 213, and a drain port 214. Among them, the length of the first locking key 211 is 6 mm, the height is 2 mm, the keying depth of the first locking hole 212 is 5 mm, the diameter of the second locking hole 213 is 2 mm, the keying depth is 3 mm, and the spring is fixed therein. The diameter of the drain port 214 is 4 mm. The first locking key 211 and the first locking hole 212 are located on the same side of the fixed connecting piece 21 and are used to connect with the first locking keys 211 and the first locking holes 212 of other fixed connecting pieces 21. The second locking hole 213 is located on the other side and is used to connect with the bouncing connecting piece 22. The drain port 214 is opened inside the fixed connecting piece 21. A conversion connecting pipe 5 is fixedly connected to the end of the drain port 214. The conversion connecting pipe 5 includes a water inlet end and a water outlet end. The water inlet end of the conversion connecting pipe 5 is fixedly connected to a flexible water-permeable pipe 6. The flexible water-permeable pipe 6 is embedded inside the fixed connecting piece 21 through the drain port 214. The buckle 23 is hook-shaped, and the buckle material is PVC and is integrally cast with the connecting piece, which can prevent the material from softening and falling off at high temperatures.

[0038] The fixed connecting pieces 21 are fixedly connected through the first locking keys 211 and the first locking holes 212 in the lower part, and can connect the waste tire 1 and position it. The fixed connecting piece 21 is a detachable connecting piece. The pressing key of the first locking key 211 is on the side close to the outside of the retaining wall to facilitate the installation construction of the modular soil-filled tire. When not in use, the insertion part of the first locking key 211 is hidden inside the fixed connecting piece 21. During installation construction, the first locking key 211 of the fixed connecting piece 21 is aligned and installed with the first locking hole 212 of another fixed connecting piece 21, and the two fixed connecting pieces 21 are tightly connected by pressing the pressing key on the outside. This structure can achieve a tight bite and ensure the stability of the connection.

[0039] The fixed connecting member 21 has structures such as a locking key, a locking hole, and a drain port 214, which are used to connect the waste tire 1 and drain water. The waste tire 1 is connected through the locking key and locking hole structures, and at the same time, the drain inside the retaining wall is realized through the drain port 214, ensuring a firm connection between the waste tires 1, and at the same time ensuring the dryness and stability inside the retaining wall. The conversion connecting pipe 5 is a pipe connecting the drain port 214 of the fixed connecting member 21 and the external drainage system, making the drainage smoother and more efficient, and improving the drainage performance of the retaining wall. The flexible permeable pipe 6 has good flexibility and water permeability, can adapt to various complex geological conditions, and improves the drainage efficiency of the retaining wall. The end of the elastic connecting member 22 is fixedly installed with a second locking key 221, and the second locking key 221 is connected to the second locking hole 213. The elastic connecting member 22 has a locking key structure for connecting adjacent fixed connecting members 21.

[0040] The elastic connecting member 22 and the fixed connecting member 21 are connected through the second locking key 221 and the second locking hole 213 on the upper part of the fixed connecting member 2, which can overcome the possibility of the waste tire 1 flipping. The pressing key of the second locking key 221 is on the side close to the outside of the retaining wall to facilitate the installation and construction of the modular soil-filled tire. When the second locking key 221 is not in use, the pin part of the second locking key 221 is hidden inside the elastic connecting member 22. During installation and construction, the second locking key 221 of the elastic connecting member 22 is aligned with the second locking hole 213 of the fixed connecting member 21 and installed, and the two are locked and linked by pressing the pressing key on the outside.

[0041] The construction method of the waste tire retaining wall that can be monitored and automatically disassembled and replaced in this embodiment includes the following steps:

[0042] S1. Install the connecting component 2 on the waste tire 1. The connecting component 2 includes a fixed connecting member 21 and an elastic connecting member 22, and the fixed connecting member 21 and the elastic connecting member 22 are connected and disassembled through the locking key and locking hole structures.

[0043] S2. Add the filler 4 into the waste tire 1 to form a soil-filled tire module. The soil-filled tire modules are fixedly connected together through the connecting component 2 to form a stable retaining wall structure.

[0044] S3. Layer by layer, set up the tire panel and backfill the soil behind the wall layer by layer. Insert the flexible permeable pipe 6 into the drain port 214 of the fixed connecting member 21 to ensure smooth drainage inside the retaining wall. Fix the monitoring device 3 in a special box and place it inside the tire close to the side of the soil to be retained. The monitoring device 3 includes a wireless displacement sensor, a data processing module, and a power supply module, which are used to monitor the displacement and deformation of the retaining wall in real time.

[0045] S4. Turn on the wireless local area network, set parameters and conduct technical debugging on the monitoring device 3. After the construction of the waste tire retaining wall is completed, start the monitoring system to begin real-time data collection and transmission.

[0046] S5. Evaluate the stability of the retaining wall based on the data received by the terminal monitoring system. Considering the on-site situation, decide whether it is necessary to replace local tire modules or reinforce local large deformations with concrete. When replacing a tire module, first press the first lock key 211 on the lower part of the fixed connector 21 to unlock the fixed connectors 21. If the first lock key 211 does not fully retract into the connector after unlocking, simply move the button outside the first lock key 211 to completely separate the connection. Then press the second lock key 221 of the spring connector 22 to unlock the fixed connector 21 and the spring connector 22. After the connectors are unlocked, use a jack and formwork to temporarily support in place of the tire module, replace it with a new soil-filled tire module, lock it through the connectors, and finally remove the temporary support structures such as the jack.

[0047] For example Figure 10 , the waste tire retaining wall that can be monitored and automatically disassembled and replaced in this embodiment can be applied to road projects in mountainous areas or high slope areas. The deformation of the waste tire retaining wall mainly occurs at the bottom and middle of the wall. According to actual needs, wireless displacement monitoring devices 3 are placed at the bottom, middle, and top of the wall at certain intervals. This device is small in size, light in weight, and easy to install, achieving portable installation and low-cost maintenance in complex environments such as mountain slopes, and can extend the service life of the device, being economical and practical. The soil-filled tire modules are fixedly installed through the connection components 2 integrally formed with nylon material, reducing the labor cost and the complexity of installation compared to manual drilling and tying. Through the monitoring device 3, the structural deformation and stability of the road retaining wall under vehicle load and self-weight can be monitored in real time. For large deformations, to avoid the situation where simply replacing local soil-filled tire structures cannot meet the overall stability requirements of the retaining wall, local concrete reinforcement can be carried out.

[0048] For example Figure 11, the waste tire retaining wall that can be monitored and automatically replaced in this embodiment can be applied to slope reinforcement in high-slope areas. The reasons for slope instability are complex and variable, but continuous rainfall remains the main inducement for most slope instabilities. Common treatment methods for slope prevention and control mainly include slope protection methods such as plastering with cement mortar, shotcreting, masonry retaining walls with stone, anchor shotcreting slope protection, and anchor shotcrete mesh slope protection, as well as methods of establishing retaining structures such as retaining walls, anchor retaining walls, and anti-slide piles. To reduce the use of steel bars and concrete by using recyclable materials, with the rapid increase in the number of automobiles, a large number of waste tires 1 are generated every year. Discarding them will not only cause serious pollution and waste of resources but also pose safety hazards. Waste tires have good mechanical properties and are widely used as a recyclable building material. According to the analysis of the rupture surface of the slope, the monitoring device 3 in this invention is mainly installed at the bottom of the retaining wall. The stability of the retaining wall can be understood in real time according to the data received by the monitoring system. According to the received data, potential slope instability conditions can be intervened in a timely manner, which can play a very good role in prevention and control.
