Description

Technical Field

[0001] The invention belongs to retaining walls, in particular to a waste tire retaining wall capable of being monitored and automatically dismantled and replaced and a construction method thereof. Background Art

[0002] In order to promote the application of modular waste tire retaining walls, when they are used in important embankment sections or retaining parts of mountains prone to landslides, new engineering technologies are urgently needed to timely detect the danger of damage to tire retaining walls in operation and how to replace and reinforce dangerous parts in a timely manner. Generally, most monitoring technologies for retaining walls require manual on-site data collection on a regular basis, which is labor-intensive and has poor timeliness.

[0003] Traditional tire retaining wall construction usually relies on stacking whole tires filled with soil, drilling holes in the tires, and then tying them with nylon rolling belts to achieve connection and positioning between tires. However, this construction method has significant defects. First, the drilling and tying process is cumbersome, which not only consumes a lot of construction time and manpower, but also the accuracy and precision of the drilling are often difficult to guarantee, which directly affects the overall strength and stability of the wall. Secondly, once the wall structure is partially damaged or deformed, the repair or reinstallation work will become extremely difficult due to the complex connection method between the tires and the difficulty of disassembly. In terms of monitoring technology, traditional retaining wall monitoring mainly relies on manual regular on-site data collection. This method is not only labor-intensive, but also has poor timeliness and is difficult to capture small deformations or abnormal conditions of the wall in a timely manner. Although there are many wireless monitoring methods on the market, such as anchor rods for monitoring deformation, positioning monitors arranged on slopes or rocks, etc., these devices are poor in practicality and durability when applied to important embankment sections or retaining parts of mountains prone to landslides.

[0004] In general, existing tire retaining walls have problems such as long construction time, high labor consumption, and difficulty in timely capturing small deformations or abnormalities of the wall. Summary of the invention

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

[0006] Technical solution: The waste tire retaining wall that can be monitored and automatically replaced described in the present invention includes waste tires, connecting components, monitoring devices and fillers. The waste tires are connected to each other through the connecting components. The monitoring device is arranged on one side of the waste tires close to the retaining body, and the waste tires are filled with fillers; the connecting components include a fixed connector and a bouncing connector, the fixed connector is connected to the bouncing connector, and the surfaces of the fixed connector and the bouncing connector are both provided with buckles for fixing the waste tires; and a wall is provided with backfill on one side of the waste tires.

[0007] Furthermore, the connection component is a one-step molding of a nylon composite material with a thickness of 4 to 6 mm.

[0008] Furthermore, the fixed connecting member includes a first locking key, a first locking hole, a second locking hole and a drain outlet. 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 connecting member. The second locking hole is arranged near the bouncing connecting member and connected thereto, and the drain outlet is arranged near the first locking hole.

[0009] Further, a second lock key is provided at the end of the spring connector, and the second lock key is connected to the second lock hole. The drain port is connected to the conversion connection pipe. The conversion connection pipe is connected to the soft water-permeable pipe. The conversion connection pipe includes a water inlet end and a water outlet end, the water inlet end is connected to the soft water-permeable pipe, and the water outlet end is inserted into the drain port of the fixed connector.

[0010] Furthermore, the fixed connecting piece is L-shaped, and the spring connecting piece is straight-line.

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

[0012] The construction method of a waste tire retaining wall capable of being monitored and automatically replaced according to the present invention comprises the following steps:

[0013] S1. Install the fixed connector on the waste tire;

[0014] S2, adding fillers to waste tires to form soil-filling tire modules, and the waste tires are fixedly connected together by connecting components to form a stable retaining wall structure;

[0015] S3, build the tire panels in layers, and backfill the wall layer by layer, connect the soft permeable pipe, fix the monitoring device in the box, and place it in the waste tire close to the retaining body;

[0016] S4. Perform parameter setting and technical debugging on the monitoring device, start 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 connector, the conversion connecting pipe and the soft 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 and effectively prevents water damage to the retaining wall structure. The flexibility and permeability of the soft permeable pipe enable the retaining wall to adapt to various complex geological conditions. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] like Figures 1-2The waste tire retaining wall that can be monitored and automatically replaced includes a waste tire 1, a connecting component 2, a monitoring device 3 and a filler 4. The waste tire 1 is fixedly connected through the connecting component 2, the monitoring device 3 is placed on the side of the waste tire 1 close to the soil, and the filler 4 is filled in the waste tire 1. The waste tire 1 is the main structural unit of the retaining wall. A solid barrier is formed by stacking and connecting the waste tires 1. The backfill wall on one side is filled with soil, which effectively blocks the sliding and collapse of the soil. The connecting component 2 with a movable mouth is formed by a nylon composite material at one time, with a thickness of 4-6mm. The connection and disassembly are realized by a lock key and a lock hole structure. The strength and toughness of the connecting component 2 ensure the tight connection between the waste tires, avoiding the loosening and deformation of the retaining wall, and the nylon composite material has good corrosion resistance, wear resistance and aging resistance, which prolongs the service life of the connecting component 2 and is easy to disassemble and replace. The monitoring device 3 is composed of a wireless displacement sensor, a data processing module and a power module, and is used to monitor the displacement deformation of the retaining wall in real time. The displacement deformation of the retaining wall is monitored by the wireless displacement sensor, the data processing module processes and analyzes the monitoring data, and the power module provides power support for the monitoring device. The filler 4 is a material filled in the waste tire 1, which increases the weight and stability of the waste tire 1 and improves the anti-slip ability of the retaining wall.

[0036] According to the analysis of the fracture surface of the slope, the monitoring equipment in this invention is mainly placed 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, the potential instability of the slope can be intervened in time, which can play a good preventive role.

[0037] like Figures 3 to 9The connection assembly 2 includes a fixed connector 21 and a pop-up connector 22, wherein the fixed connector 21 is connected to the pop-up connector 22, and buckles 23 are provided on the surfaces of the fixed connector 21 and the pop-up connector 22. The fixed connector 21 is L-shaped, and the pop-up connector 22 is linear. The fixed connector 21 includes a first lock key 211, a first lock hole 212, a second lock hole 213, and a drain 214, wherein the lock key 211 is 6 mm long and 2 mm high, the lock hole 212 can be keyed to a depth of 5 mm, the second lock hole 213 is 2 mm in diameter and can be keyed to a depth of 3 mm, and a spring is fixed therein, and the diameter of the drain 214 is 4 mm. The first lock key 211 and the first lock hole 212 are located on the same side of the fixed connector 21, and are used to be connected to the first lock key 211 and the first lock hole 212 of other fixed connectors 21. The second lock hole 213 is located on the other side and is used to connect with the spring connector 22. The drain port 214 is opened inside the fixed connector 21. The end of the drain port 214 is fixedly connected with a conversion connection pipe 5, and the conversion connection pipe 5 includes a water inlet end and a water outlet end. The water inlet end of the conversion connection pipe 5 is fixedly connected with a soft water-permeable pipe 6. The soft water-permeable pipe 6 is embedded in the fixed connector 21 through the drain port 214. The buckle 23 is hook-shaped, and the buckle material is PVC and is cast as a whole with the connector to prevent the material from softening and falling off at high temperature.

[0038] The fixed connector 21 is fixedly connected through the first lock key 211 and the first lock hole 212 of the lower part, and can connect the waste tire 1 and position it. The fixed connector 21 is a detachable connector, and the pressing key of the first lock key 211 is on the side close to the outside of the retaining wall to facilitate the installation and construction of the modular tire. When not in use, the pin part of the first lock key 211 is hidden in the fixed connector 21. During installation and construction, the first lock key 211 of the fixed connector 21 is aligned with the first lock hole 212 of another fixed connector 21, and the two fixed connectors 21 are tightly connected by pressing the external pressing key. This structure can achieve tight engagement and ensure the stability of the connection.

[0039] The fixed connector 21 has a lock key, a lock hole, and a drain port 214, etc., which are used to connect the waste tire 1 and drainage. The waste tire 1 is connected through the lock key and lock hole structure, and the drainage inside the retaining wall is achieved through the drain port 214, which ensures the firm connection between the waste tires 1 and the dryness and stability of the interior of the retaining wall. The conversion connecting pipe 5 is a pipe connecting the drain port 214 of the fixed connector 21 and the external drainage system, which makes the drainage smoother and more efficient, and improves the drainage performance of the retaining wall. The soft 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 bouncing connector 22 is fixedly installed with a second lock key 221, and the second lock key 221 is connected to the second lock hole 213. The bouncing connector 22 has a lock key structure, which is used to connect adjacent fixed connectors 21.

[0040] The bouncing connector 22 and the fixed connector 21 are connected through the second lock key 221 and the second lock hole 213 on the upper part of the fixed connector 2, which can overcome the possibility of the waste tire 1 turning over. The pressing key of the second lock key 221 is on the side close to the outer side of the retaining wall to facilitate the installation and construction of the modular soil plugging tire. When the second lock key 221 is not in use, the pin part of the second lock key 221 is hidden in the bouncing connector 22. During installation and construction, the second lock key 221 of the bouncing connector 22 is aligned and installed with the second lock hole 213 of the fixed connector 21, and the two are locked and linked by pressing the external press key.

[0041] The construction method of the waste tire retaining wall capable of being monitored and automatically dismantled in this embodiment comprises the following steps:

[0042] S1. Install the connection assembly 2 on the waste tire 1. The connection assembly 2 includes a fixed connection member 21 and a spring connection member 22. The fixed connection member 21 and the spring connection member 22 are connected and disassembled through a lock key and a lock hole structure.

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

[0044] S3. Layered tire panels are set up, and the wall is backfilled layer by layer and then the soil is backfilled. The soft permeable pipe 6 is inserted into the drainage port 214 of the fixed connector 21 to ensure smooth drainage inside the retaining wall. The monitoring device 3 is fixed in a special box and placed inside the tire close to the retaining body. The monitoring device 3 includes a wireless displacement sensor, a data processing module and a power module, which are used to monitor the displacement and deformation of the retaining wall in real time.

[0045] S4, open the wireless local area network, set parameters and perform technical debugging on the monitoring device 3, and after completing the construction of the waste tire retaining wall, start the monitoring system and start real-time data collection and transmission.

[0046] S5. Evaluate the stability of the retaining wall according to the data received by the terminal monitoring system, and comprehensively consider the on-site conditions to decide whether it is necessary to replace the local tire module or to reinforce the local large deformation with concrete. When the tire module needs to be replaced, first press the first lock key 211 at the lower part of the fixed connector 21 to unlock the fixed connector 21. If the first lock key 211 is not completely retracted into the connector after unlocking, just move the button outside the first lock key 211 to completely separate the connection, and then press the second lock key 221 of the bouncing connector 22 to unlock the fixed connector 21 and the bouncing connector 22. After the connector is unlocked, use a jack and a template to temporarily support the tire module instead, replace the new soil-blocking tire module, and lock it through the connector, and finally remove the temporary support structure such as the jack.

[0047] like Fig.10 The waste tire retaining wall of this embodiment that can be monitored and automatically replaced can be applied to road projects in mountainous areas or high slope areas. The deformation of the waste tire 1 retaining wall is mainly at the bottom and middle of the wall. In order to meet the needs of the actual situation, wireless displacement monitoring devices 3 are placed at the bottom, middle and top of the wall at certain intervals. The equipment is small in size, light in weight and easy to install, which realizes portable installation and low-cost maintenance in complex environments such as mountain slopes, and can extend the service life of the equipment. It is economical and practical. The retaining tire modules are fixedly installed through the connecting components 2 integrally formed of nylon material, which reduces the labor cost and the complexity of installation compared to manual drilling and binding. The monitoring device 3 can realize real-time monitoring of the structural deformation and stability of the road retaining wall under the action of vehicle load and deadweight. For large deformation, in order to avoid the situation that only the replacement of the local retaining tire structure cannot meet the overall stability requirements of the retaining wall, the local concrete reinforcement can be carried out.

[0048] like Fig.11 The waste tire retaining wall of this embodiment that can be monitored and automatically replaced can be applied to the reinforcement of slopes in high slope areas. The causes of slope instability are complex and varied, but continuous rainfall is still the main cause of most slope instability. Common slope prevention and control treatment methods mainly use cement mortar plastering, spraying, mortar-laid stone retaining wall, anchor spraying slope protection, anchor spraying net slope protection and other slope protection methods and methods of establishing retaining walls, anchor rod retaining walls, anti-sliding piles and other retaining structures. In order to use recyclable materials to reduce the use of steel bars and concrete, with the rapid increase in the number of cars, a large number of waste tires are generated every year. Throwing away will not only cause serious pollution and waste of resources, but also have safety hazards. Waste tires have good mechanical properties and are widely used as a recyclable building material. According to the analysis of the fracture surface of the slope, the monitoring equipment in the invention is mainly placed at the bottom of the retaining wall, and 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, the potential instability of the slope can be intervened in time, which can play a good preventive role.
