Description

Technical Field

[0001] This invention relates to the field of high embankment engineering technology, and in particular to a vibration reinforcement device for high embankments. Background Technology

[0002] High embankments are earthwork structures with a large embankment height formed by artificial filling. They are commonly used in infrastructure construction such as mountain roads, railways, airports, and ports to cross valleys or create flat sites.

[0003] In traditional high fill construction, the fill material needs to be compacted using external compaction equipment, such as vibratory rollers and rammers, to improve its density and stability. However, due to the limitations of the operating methods and coverage of the compaction equipment, some areas of the high fill, such as edges, corners, and junctions of different fill materials, are prone to compaction blind spots, which cannot be fully compacted.

[0004] In addition, to improve the anti-sliding stability and overall strength of high embankments, it is necessary to lay reinforcing materials, such as geogrids and steel mesh, in the high embankments. However, traditional reinforcing materials can only play a passive tensile strengthening role in high embankments. That is, the reinforcing materials only passively bear the tensile force when the high embankment is deformed by external forces, thereby enhancing the stability of the high embankment. Summary of the Invention

[0005] The purpose of this invention is to provide a vibration reinforcement device for high fill, so as to solve the technical problems of existing compaction equipment having many limitations and poor compaction effect, and reinforcement materials having a single effect.

[0006] To achieve this objective, the present invention adopts the following technical solution: A vibration reinforcement device for high embankments, comprising: The reinforcing mesh is composed of multiple reinforcing units connected to each other, and the interior of each reinforcing unit forms an accommodating space. A vibration excitation component is disposed within the accommodating space, and the vibration excitation component is capable of generating vibration and transmitting it to the stiffening unit; A control module, connected to the excitation component via a signal, is used to adjust the vibration parameters of the excitation component, wherein the vibration parameters include vibration frequency, vibration amplitude, and vibration duration. The power supply module is electrically connected to the excitation component and the control module, and is used to supply power to the excitation component and the control module.

[0007] Preferably, the reinforcing unit includes a main structure, the outer surface of which is provided with an anti-slip structure, and the main structure has a through cavity extending along its own axis, the through cavity constituting the accommodating space.

[0008] Preferably, the anti-slip structure includes anti-slip protrusions, and a plurality of the anti-slip protrusions are disposed on the top of the main structure and arranged at intervals along the axial direction of the main structure.

[0009] Preferably, the cross-sectional area of ​​the anti-slip protrusion perpendicular to the axis of the main structure gradually decreases in the direction away from the main structure, so that the outer surface of the anti-slip protrusion forms an anchoring slope.

[0010] Preferably, the anti-slip structure includes anchoring claws, a plurality of anchoring claws are disposed on the side of the main structure and are arranged at intervals along the axial direction of the main structure, the radial width of the anchoring claws gradually decreases in the direction away from the main structure, and an anchoring tip is formed at the end of the anchoring claw.

[0011] Preferably, the anchoring claw extends outward and downward in an arc shape from the side surface of the main structure, and the anchoring tip is lower than the bottom surface of the main structure in the vertical direction.

[0012] Preferably, a positioning mechanism is also included, which includes a movable anchor rod and a driving member. The driving member is disposed in the reinforcement unit, and the movable anchor rod is connected to the output end of the driving member. The driving member can control the movable anchor rod to be housed in the reinforcement unit or to be deployed relative to the reinforcement unit.

[0013] Preferably, the two ends of the reinforcing unit are provided with a connecting structure, and two adjacent reinforcing units are detachably connected through the connecting structure.

[0014] Preferably, the system also includes an energy recovery component disposed within the accommodating space. The energy recovery component includes an inertial mass block, a piezoelectric transducer, and an energy storage unit. The inertial mass block is suspended in the accommodating space by an elastic element. When the excitation component operates, it can cause the stiffening unit to vibrate, causing the inertial mass block to displace and compress the piezoelectric transducer to generate electricity. The electrical energy is then stored in the energy storage unit to provide auxiliary power to the control module.

[0015] Preferably, the reinforcing unit has a drainage channel independent of the accommodating space, the drainage channel is provided through the thickness direction of the reinforcing unit, and the outer surface of the reinforcing unit has a guide groove that communicates with the drainage channel.

[0016] The beneficial effects of this invention are: The proposed vibration reinforcement device for high fills integrates the previously independent functions of reinforcement and vibration compaction by embedding the excitation component within the reinforcement unit's accommodating space, achieving synergistic effects between structure and function. After the reinforcement mesh is embedded in the high fill, it provides tensile reinforcement, constrains lateral deformation of the soil, and enhances the overall stability of the high fill. Simultaneously, the excitation component embedded in the reinforcement unit can be activated under the control module's command, generating vibration and transmitting it to the surrounding reinforcement units and the entire reinforcement mesh. This transforms the reinforcement mesh from a passively stressed state to one that actively applies vibration compaction to the surrounding fill material. Because the reinforcement mesh is extensively laid within the high fill, the vibration generated by the excitation component is emitted directly from within the fill material, particularly from key areas such as edges, corners, and material interfaces where traditional external compaction equipment is difficult to effectively operate. This achieves uniform compaction from the inside out without blind spots, improving the density and uniformity of the fill material. Secondly, the active vibration process of the reinforcing mesh can dynamically optimize the interaction between the reinforcing mesh and the surrounding soil and rock fill during the construction phase. Vibration not only causes the fill particles to rearrange and tightly wrap the reinforcing unit, enhancing the interlocking and friction at the interface, but also improves the synergistic performance between the reinforcing material and the fill, allowing the reinforcement effect to be achieved earlier and stronger, rather than relying solely on passive tightening after high fill deformation. Furthermore, by adjusting the vibration parameters of the excitation component through the control module, this vibration reinforcement device can flexibly adapt to the needs of different engineering stages. For example, stronger vibration can be used in the initial laying stage to facilitate fill compaction and density, while parameters can be adjusted in the later stages for micro-vibration maintenance or to adapt to different fill characteristics, thus achieving intelligent and precise control of the construction process and reinforcement effect.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

"Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0022] In the section on specific implementation methods, to enable those skilled in the art to better understand the technical solution of the present invention, a brief description of the high embankment involved in the present invention is provided below. A high embankment refers to an earthwork engineering structure with a relatively large filling height, formed by artificial filling. It is commonly used in infrastructure construction such as mountain roads, railways, airports, and ports to cross valleys or create flat sites.

[0023] High embankments typically sit on natural or treated foundations, and are layered granular structures, resembling large soil or soil-rock mixture structures. The long-term stability and safety of high embankments depend primarily on the compaction, uniformity, overall strength, and resistance to uneven settlement and slope slippage of the embankment.

[0024] In traditional construction, the compaction of fill material is mainly achieved through external mechanical rolling or tamping, and high fill structures are reinforced by layering reinforcing materials. However, external compaction equipment has limitations in its depth and range of action, and can easily create areas of insufficient compaction in complex structural parts; at the same time, traditional reinforcing materials work in a passive tensile manner, and their synergistic potential with the fill material is not fully realized.

[0025] This invention addresses the shortcomings of the prior art by providing a vibration reinforcement device integrated within high embankments that actively functions. The technical solution of this invention will be further described below with reference to the accompanying drawings and specific embodiments to make the objectives, technical solutions, and advantages of this invention clearer.

[0026] See Figures 1 to 5 The vibration reinforcement device for high embankments provided in this embodiment of the invention includes a reinforcement mesh 1, a vibration excitation component 6, a power supply module, and a control module. The reinforcement mesh 1 is formed by interconnecting multiple reinforcement units 2, with each reinforcement unit 2 forming an accommodating space 20. The vibration excitation component 6 is disposed within the accommodating space 20, generating vibration and transmitting it to the reinforcement units 2. The control module is signal-connected to the vibration excitation component 6 and is used to adjust the vibration parameters of the vibration excitation component 6, including vibration frequency, vibration amplitude, and vibration duration. The power supply module is electrically connected to the vibration excitation component 6 and the control module, and is used to supply power to both components.

[0027] The vibration reinforcement device for high fills proposed in this invention integrates the two previously independent functions of reinforcement and vibration compaction by embedding the excitation component 6 within the accommodating space 20 of the reinforcement unit 2, achieving synergistic effects between structure and function. After the reinforcement mesh 1 is embedded in the fill material, the reinforcement mesh 1 itself can play a role in tensile reinforcement, restraining the lateral deformation of the soil and improving the overall stability of the high fill. At the same time, the excitation component 6 embedded in the reinforcement unit 2 can start working under the command of the control module, generating vibration and transmitting the vibration to the surrounding reinforcement units 2 and the entire reinforcement mesh 1, so that the reinforcement mesh 1 changes from a traditional passive stress state to an active vibration compaction of the surrounding fill material. Since the reinforcement mesh 1 is laid extensively inside the high fill, the vibration energy generated by the excitation component 6 can be directly emitted from the inside of the fill material, especially from key parts such as edges, corners and material interfaces that are difficult for traditional external compaction equipment to effectively reach, achieving uniform compaction from the inside out without blind spots, and improving the density and uniformity of the fill material. Secondly, the active vibration process of the reinforcing mesh 1 can dynamically optimize the interaction between the reinforcing mesh 1 and the surrounding soil and rock fill during the construction phase. The vibration not only causes the fill particles to rearrange and tightly wrap the reinforcing unit 2, enhancing the interlocking and friction of the interface, but also improves the synergistic working performance between the reinforcing mesh 1 and the fill, allowing the reinforcement effect to be achieved earlier and stronger, rather than relying solely on passive tightening after high fill deformation. In addition, by adjusting the vibration parameters of the excitation component 6 through the control module, the vibration reinforcement device can flexibly adapt to the needs of different engineering stages. For example, stronger vibration can be used in the initial laying stage to facilitate the compaction and densification of the fill, while in the later stage, the parameters can be adjusted for micro-vibration maintenance or to adapt to different fill characteristics, thereby realizing intelligent and precise control of the construction process and reinforcement effect.

[0028] The working principle and specific structure of the vibration reinforcement device will be described in detail below.

[0029] The reinforcing mesh 1 is composed of multiple independent reinforcing units 2 joined together to form an integral structure that can be laid in high fill material.

[0030] There are various feasible implementations for the specific form of the reinforcing mesh 1, which mainly depend on the connection and arrangement of the reinforcing units 2. For example, in one embodiment, multiple reinforcing units 2 can be connected horizontally and vertically to form a regular grid-like reinforcing mesh 1, thereby uniformly distributing stress in two directions in the plane.

[0031] In another embodiment, multiple reinforcing units 2 can be arranged in parallel along the same direction and fixed by transverse connectors to form a strip-shaped reinforcing mesh 1. This form is more suitable for high fill areas that require unidirectional reinforcement.

[0032] In addition, the reinforced unit 2 can also be adaptively connected according to the special shape of the high fill structure, such as the slope turning point, to form an irregular mesh layout.

[0033] It is understood that the overall size, number of units, and specific arrangement of the reinforcing mesh 1 can be adapted to the actual engineering size, design requirements, and stress characteristics of the target high fill, and this invention does not impose any limitations on this.

[0034] To facilitate transportation, on-site assembly, and adapt to the laying requirements of different high embankment areas, the two ends of the reinforced unit 2 are provided with connecting structures 5, which enable two adjacent reinforced units 2 to be detachably connected through the connecting structures 5, thereby improving the flexibility of construction and helping to adjust the shape and coverage of the reinforced mesh 1 under complex terrain or specific design.

[0035] In this embodiment, among two adjacent reinforcing units 2 that need to be connected, one reinforcing unit 2 has an insertion section 51 at its end, and the corresponding end of the other reinforcing unit 2 has a sleeve section 52 that matches the insertion section 51. The outer dimensions of the insertion section 51 are slightly smaller than the inner cavity dimensions of the sleeve section 52, so that the insertion section 51 can be smoothly inserted into the sleeve section 52. To ensure the firmness of the connection and prevent it from coming apart under vibration or force, the insertion section 51 and the sleeve section 52 need to be locked together by additional fasteners or methods. For example, corresponding threads can be provided on the outer surface of the insertion section 51 and the inner surface of the sleeve section 52, and the threaded connection can be achieved by rotation; or after insertion, a transverse bolt can be used to fasten it through the aligned pin hole; or a key connection method with a key and keyway can be used to transmit shear force.

[0036] Furthermore, in order to facilitate the rapid construction of the reinforcing mesh 1, at least some of the reinforcing units 2 can be designed with a plug-in section 51 at one end and a socket section 52 at the other end, so that multiple reinforcing units 2 can be connected into the required length or mesh structure by plugging and fixing them end to end in sequence.

[0037] Besides the aforementioned plug-in and sleeve-fitting methods, the connecting structure 5 can also have other feasible variations. For example, in another embodiment, the connecting structure 5 can adopt a snap-fit ​​form with quick-locking clips, that is, male and female connectors are respectively provided at both ends of the reinforcing unit 2, which can be locked by pressing or rotating, and the clips need to be released for disassembly. In yet another embodiment, the connecting structure 5 can also be designed as a flange connection, that is, a flange is fixed at each end of the reinforcing unit 2, and the connection is secured by multiple bolts and nuts distributed circumferentially around the flange. This method can provide a larger connection contact surface and more uniform force transmission, which is suitable for critical parts that need to withstand large tensile forces.

[0038] The specific implementation of the connection structure 5 is not limited here, as long as it can ensure that the two stiffened units 2 can be detachably connected.

[0039] Specifically, the reinforced unit 2 includes the main structure 3. The main structure 3 constitutes the basic skeleton of the reinforced unit 2. The material of the main structure 3 must have high tensile strength, good toughness and corrosion resistance. For example, it can be made of high-strength alloy steel, steel with anti-corrosion treatment or high-performance engineering plastic composite materials to ensure its reliability in the complex stress environment of high fill and in long-term use.

[0040] The main structure 3 has a through cavity 30 extending along its own axis, which forms an accommodating space 20 for accommodating the excitation component 6. The design of the through cavity 30 allows the excitation component 6 to be installed from one end of the stiffening unit 2 and facilitates the layout and connection of the circuit of the excitation component 6.

[0041] Considering the harsh environment of the high fill, which is humid and even underwater, to prevent moisture and dampness from invading the through cavity 30 and causing corrosion, short circuits, or other damage to the excitation assembly 6 and power supply lines, a preferred embodiment of this solution provides a waterproof and moisture-proof layer on the inner wall of the through cavity 30. This waterproof and moisture-proof layer can be a waterproof sealant or epoxy resin coating applied to the inner wall of the through cavity 30, or a flexible waterproof sleeve fitted over the inner wall of the through cavity 30. This creates a relatively dry and stable microenvironment within the accommodating space 20, improving the long-term reliability and service life of the electrical components of the internal excitation assembly 6.

[0042] The outer surface of the main structure 3 is provided with an anti-slip structure 4. The anti-slip structure 4 is designed to increase the friction coefficient and mechanical interlocking force between the surface of the reinforced unit 2 and the surrounding soil and rock fill. In actual engineering, the anti-slip structure 4 can take various forms, such as regular or irregularly distributed protrusions, particles, corrugations, or threads on the surface; it can also be a rough texture or mesh grid directly molded or welded to the surface. Its core principle is that by increasing the roughness of the contact surface, when the fill wraps around the reinforced unit 2 under compaction or stress, the anti-slip structure 4 can more effectively embed itself between the fill particles, forming a strong interfacial resistance. This not only prevents relative slippage between the reinforced unit 2 and the fill, ensuring the full realization of the reinforcement effect, but also, when the vibration assembly 6 is working, the vibration energy transmitted through the anti-slip structure 4 acts more directly and effectively on the adjacent fill layer, improving the efficiency of local compaction and interfacial bonding.

[0043] In this embodiment, the anti-slip structure 4 is an anti-slip protrusion 41 disposed on the top of the main structure 3. Multiple anti-slip protrusions 41 are arranged regularly or irregularly at certain intervals along the axial direction of the main structure 3. When the reinforcing unit 2 is horizontally laid in the filler layer, the anti-slip protrusions 41 directly contact the overlying filler material from the top.

[0044] Preferably, the cross-sectional area of ​​the anti-slip protrusion 41 perpendicular to the axis of the main structure 3 is designed to gradually decrease in the direction away from the main structure 3, so as to form a conical or wedge-shaped anti-slip protrusion 41 geometry, so that the outer surface of the anti-slip protrusion 41 naturally forms an anchoring slope 411. When the overlying filler settles under its own weight, rolling or vibration, the filler particles will slide along the anchoring slope 411 and tightly embed, generating a clamping force perpendicular to the anchoring slope 411, thereby forming a strong biting and locking effect on the reinforcing unit 2 in the vertical direction, improving the pull-out resistance and enhancing the efficiency of vibration energy transmission to the upper filler.

[0045] In addition, the anti-slip structure 4 may also include, or simultaneously include, anchoring claws 42 disposed on the side of the main structure 3. Multiple anchoring claws 42 are arranged at intervals along the axial direction of the main structure 3, the radial width of the anchoring claws 42 gradually decreases in the direction away from the main structure 3, and sharp anchoring tips 421 are formed at the ends of the anchoring claws 42.

[0046] Furthermore, the anchoring claw 42 extends outward and downward in an arc shape from the side surface of the main structure 3, and ultimately makes the vertical height of the anchoring tip 421 lower than the bottom surface of the main structure 3.

[0047] When the reinforced unit 2 is placed on the fill material and begins to cover the new fill layer, the downward-bent anchoring claws 42 are pre-embedded in the lower fill material. As construction progresses, the design of the anchoring tip 421 being lower than the bottom surface of the reinforced unit 2 allows the anchoring claws 42 to penetrate deeper into the lower fill material. When the high fill is subjected to horizontal shear force or the reinforced unit 2 tends to be pulled out, the arc-shaped bent claws, with their strong bending stiffness, effectively diffuse the tensile force into a larger area of ​​the surrounding soil through the lateral resistance provided by the anchoring tip 421 and the arc surface. At the same time, the downward extension also enhances the linkage with the lower fill material, allowing vibration energy to be transmitted more effectively to deeper layers.

[0048] Furthermore, the specific dimensions of the anti-slip protrusions 41 and anchoring claws 42 can be specifically designed according to the maximum particle size, gradation, and mechanical properties of the filler to achieve the optimal interlocking effect. For example, for coarse-grained high fill, larger anti-slip protrusions 41 and anchoring claws 42 can be used; for fine-grained high fill, the distribution density of anti-slip protrusions 41 and anchoring claws 42 can be increased.

[0049] The anti-slip structure 4 can be integrally formed with the main structure 3, or it can be mechanically fixed to the surface of the main structure 3 as an independent wear-resistant part, facilitating replacement after wear. When the vibration excitation component 6 is working, the vibration is transmitted through the main structure 3 to each anti-slip protrusion 41 and anchoring claw 42, and the multiple anti-slip protrusions 41 and anchoring claws 42 can generate a strong directional kneading and compaction effect on the filler particles in direct contact.

[0050] To further ensure that the vibration reinforcement device remains stably positioned after being laid in the fill material, preventing accidental displacement during subsequent filling material covering, compaction, or its own vibration, this device also includes a positioning mechanism. The positioning mechanism includes a movable anchor rod and a drive component. Specifically, the drive component is mounted on the reinforcement unit 2, for example, it can be embedded in the side wall or end of the main structure 3 of the reinforcement unit 2, and is electrically connected to the internal power supply module and control module. The movable anchor rod is connected to the output end of the drive component. The drive component can receive commands from the control module and output linear or rotary motion, thereby controlling the movable anchor rod to perform two states: one state is controlling the movable anchor rod to be retracted into the reinforcement unit 2 or close to its outer surface, in which case the overall contour of the reinforcement unit 2 is smooth, facilitating dragging or laying in the fill material layer; the other state is controlling the movable anchor rod to extend relative to the reinforcement unit 2, that is, driving the movable anchor rod to extend radially or obliquely, so that its tip penetrates deep into the surrounding fill material.

[0051] During the installation of the reinforcing mesh 1, the control drive unit keeps the movable anchor rod in a retracted state. At this time, the entire reinforcing unit 2 has a regular shape and can be smoothly placed at the predetermined elevation and position without the movable anchor rod hooking the fill material or interfering with the installation. After the reinforcing mesh 1 is laid in place, the control module issues a command, and the drive unit operates to push or screw the movable anchor rod into the surrounding dense fill material. The unfolded movable anchor rod works in conjunction with the anti-slip structure 4 on the surface of the aforementioned reinforcing unit 2 to improve the reinforcing mesh 1's resistance to horizontal movement and floating. The active vibration of the excitation component 6, while compacting the fill material, may also generate a reaction force on the device itself, posing a risk of loosening or shifting the reinforcing mesh 1. The positioning mechanism provides a strong reverse gripping force through the unfolded movable anchor rod, ensuring the absolute stability of the entire reinforcing mesh 1 in the vibration environment, thereby guaranteeing the controllability and uniformity of the vibration compaction effect.

[0052] The driving component can be implemented in various ways, such as using a miniature electric actuator, a linear motor, or a worm gear mechanism driven by a motor to achieve linear extension; alternatively, a rotary motor combined with a screw can be used to achieve rotary drilling deployment of the movable anchor bolt. The movable anchor bolt can be a straight rod with a sharp end, and the rod body can be equipped with barbs or ridges to enhance the anchoring force; it can also be designed as a helical rod, which deploys through rotary drilling, causing less disturbance to the filler and providing greater anchoring force. The positioning mechanism can be symmetrically arranged on both sides or around the reinforcing unit 2 to form a balanced anchoring.

[0053] Preferably, to improve the performance of the device in saturated or seepage environments, the reinforced unit 2 has drainage channels independent of the accommodating space 20. The drainage channels extend along the thickness direction of the reinforced unit 2, forming a path that allows water to pass through. Furthermore, guide grooves connecting the drainage channels are formed on the outer surface of the reinforced unit 2 that contacts the packing material. These guide grooves are distributed in a mesh pattern or extend along a specific direction; their design increases the water collection area and improves drainage efficiency.

[0054] When seepage water exists within the high embankment, the water flow can be collected through the guide grooves on the outer surface of the reinforced unit 2 and quickly discharged through the through-hole drainage channels. This effectively reduces the pore water pressure at the interface between the reinforced unit 2 and the soil, preventing moisture accumulation and softening of the interface, thereby maintaining or even enhancing the frictional resistance between the reinforced unit 2 and the surrounding fill material. It can also maintain the strength of adjacent fill material and prevent its deterioration due to excessive moisture content. Since the drainage channels and the accommodating space 20 are independent of each other, it ensures that the environment of the core electrical components such as the vibration excitation assembly 6 and the power supply module is dry and safe, unaffected by the drainage function.

[0055] The vibration excitation component 6 is integrated within the accommodating space 20. The vibration excitation component 6 is capable of generating controllable mechanical vibration and directly transmitting the vibrational energy to the stiffening unit 2 in which it is located.

[0056] In one embodiment, the excitation assembly 6 mainly includes a vibration generator and a fixed base. The vibration generator can be an eccentric block type vibration motor. The fixed base is rigidly connected to the inner wall of the accommodating space 20, and the vibration generator is mounted on the fixed base. Thus, the excitation force generated by the vibration generator during operation acts directly on the main structure 3 of the stiffening unit 2 through the fixed base, causing it to vibrate.

[0057] The inner wall of the accommodating space 20 is further provided with buffer or damping material to optimize vibration transmission or suppress harmful resonance at a specific frequency.

[0058] The working principle of the vibration excitation component 6 is to introduce vibration waves into the surrounding soil and rock fill material through the reinforcement unit 2. The vibration causes a temporary reduction in the frictional resistance between the fill material particles. Under the action of inertial force and gravity, the fill material particles are rearranged and tend to a denser and more stable state. This process achieves active compaction of the fill material's interior. At the same time, the continuous vibration strengthens the interlocking and friction between the fill material particles and the anti-slip structure 4 on the surface of the reinforcement unit 2, improving the interfacial shear strength.

[0059] To adapt to different engineering needs, the vibration excitation assembly 6 has multiple implementation methods. For example, the vibration generator can be hydraulically driven to meet high power requirements.

[0060] In another embodiment, two or more vibration generators may be provided in a single accommodating space 20. The mounting axes of the multiple vibration generators are perpendicular to each other or at a specific angle, so that the excitation assembly 6 can generate linear vibration or composite vibration in different directions, thereby optimizing the compaction effect for different filler characteristics.

[0061] Furthermore, the vibration excitation component 6 can be designed as a distributed module. In the reinforced unit 2 with a relatively long through cavity 30, multiple independent vibration generating units can be arranged at axial intervals along the through cavity 30. Each vibration generating unit is independently controlled by the control module, thereby allowing for differentiated vibration treatment of different areas of the high fill.

[0062] Furthermore, the vibration excitation assembly 6 also includes a sensing unit. Specifically, the sensing unit includes a vibration sensor integrated into the fixed base, used to monitor the vibration state of the reinforcement unit 2. The control module can adjust the operating parameters of the vibration generator in real time based on the feedback signal from the vibration sensor, such as the start or stop of the vibration generator, vibration frequency, vibration amplitude, and vibration duration, so that the compaction process adapts to the dynamic changes in the density of the filler, achieving adaptive intelligent control.

[0063] In addition, the sensing unit also includes a position sensor. The position sensor is used to monitor the spatial position of the stiffened unit 2. Specifically, the position sensor is integrated into the fixed base or the stiffened unit 2. The type of position sensor can be an electromagnetic induction displacement sensor or a gravity induction displacement sensor, etc., which will not be elaborated here. Its working principle is to obtain the position data of the stiffened unit 2 by continuously or intermittently measuring the absolute coordinates or relative displacement of the stiffened unit 2.

[0064] After the reinforcing mesh 1 has been installed in a high fill for a long period of time, uneven settlement may occur due to the consolidation, rheology of the fill material, or the action of external loads. This can lead to unexpected displacement or deformation of the reinforcing mesh 1. Position sensors can detect changes in the position of the reinforcing mesh 1 in real time or periodically and transmit the data to the control module. The built-in analysis program in the control module can analyze and process the position data, such as calculating displacement, displacement rate, or deviation from the initial design position. Furthermore, the position data is uploaded to a remote monitoring center via a wireless communication unit for long-term health monitoring and safety assessment of the reinforcing mesh 1.

[0065] The power supply module is electrically connected to the excitation component 6 and the control module, and is used to provide a stable power output for the operation of the excitation component 6, and to provide working power for the logic operation and signal transmission and reception of the control module.

[0066] The power supply module includes an energy storage unit and a power interface. The energy storage unit is preferably a rechargeable battery pack, the capacity of which is configured according to the power of the driven excitation component 6 and the expected operating time. The power interface can be a wired interface, used to connect to a temporary power supply or centralized power supply system via an external cable for power supplementation during the construction phase; or it can be a wireless charging receiving coil, used for charging via contactless energy transfer.

[0067] The power supply module is encapsulated in a waterproof, moisture-proof and pressure-resistant housing. The housing is fixed in the accommodating space 20 of the reinforcement unit 2 or integrated with the main body of the reinforcement unit 2 to resist the damp, seepage and soil pressure environment inside the high fill.

[0068] In addition, the power supply module also includes an energy management unit. The energy management unit can monitor the remaining power, output voltage, and current of the energy storage unit in real time and communicate with the control module. The control module can intelligently schedule the operating mode and time of the excitation component 6 based on the engineering plan, vibration strategy, and remaining power information to optimize energy consumption.

[0069] Furthermore, a piezoelectric material component is integrated externally or internally into the housing. Specifically, the piezoelectric material component comprises one or more layers of piezoelectric material. The piezoelectric material can be composed of piezoelectric ceramics or piezoelectric thin films. The piezoelectric material is adhered to the outer surface of the housing in contact with the filler, or encapsulated within the housing at a location coupled to the vibration transmission path. When the filler undergoes slight deformation due to its own weight, load, or changes in internal stress, or when vibrations are caused by construction machinery, traffic, etc., in the external environment, these mechanical actions are transmitted to the housing, causing the piezoelectric material to deform. When the piezoelectric material deforms, its internal electrodes generate a charge proportional to the strain, thereby directly converting external mechanical energy into electrical energy. The generated electrical energy is transmitted through wires to the power supply circuit of the sensing unit, thus recharging the sensing unit and enabling it to maintain continuous sensing performance even without external power supply.

[0070] In addition, the vibration reinforcement device also includes an energy recovery component, which is disposed within the accommodating space 20. The energy recovery component includes an inertial mass, piezoelectric transducers, and an energy storage unit. Specifically, the inertial mass is suspended on a support in the accommodating space 20 by an elastic element, such as a helical spring or an elastic diaphragm, allowing the inertial mass to move freely within a certain range. One or more piezoelectric transducers are disposed along the movement path of the inertial mass, for example, fixed to the inner wall of the support. The position of the piezoelectric transducers ensures that they can contact and be compressed when the inertial mass undergoes a large displacement. The energy storage unit is electrically connected to the piezoelectric transducers.

[0071] When the excitation component 6 operates and causes the stiffened unit 2 to vibrate as a whole, the suspended inertial mass block tends to maintain its original motion state due to its inertia, thus generating relative motion between itself and the vibrating shell of the stiffened unit 2. This relative motion causes the inertial mass block to periodically squeeze or impact the preset piezoelectric transducer. When subjected to mechanical stress, the piezoelectric transducer generates an electric charge, directly converting this portion of the vibrational mechanical energy that might otherwise be dissipated into electrical energy. The converted electrical energy is collected and stored in an energy storage unit. The energy storage unit can be connected to a power supply module to provide auxiliary power to the control module or sensing unit, thereby realizing the recovery and reuse of some vibrational energy during device operation and helping to improve overall energy utilization efficiency.

[0072] The control module is connected to the excitation assembly 6 and the power supply module via signal. The control module is used to receive commands or signals and generate corresponding control commands to adjust the vibration parameters of the excitation assembly 6. The vibration parameters include, but are not limited to, start, stop, vibration frequency, vibration amplitude, and vibration duration.

[0073] Specifically, the control module includes a microprocessor, a signal input interface, and a drive output circuit. The microprocessor has a pre-stored control program. The signal input interface can receive wireless or wired signals from an external control terminal, or it can be connected to a sensing unit located inside the device. The drive output circuit adjusts the current or voltage supplied to the excitation component 6 according to the instructions of the microprocessor, thereby controlling the vibration parameters.

[0074] More specifically, the control module integrates an adaptive control algorithm. This algorithm can process feedback signals from the sensing units in real time, such as the vibration acceleration response of the reinforced unit 2 itself or changes in surrounding soil pressure. By analyzing the feedback signals, the adaptive control algorithm can determine the real-time compaction state of the fill material and dynamically adjust the operating frequency and amplitude of the excitation component 6, ensuring that the excitation component 6 is always in resonance or optimal performance state, thereby achieving closed-loop control of the compacted material quality.

[0075] The specific steps for using this vibration reinforcement device are described in detail below.

[0076] This vibratory reinforcement device can be implemented in high embankment projects according to the following steps: During the layered filling construction of high embankments, multiple reinforcing units 2 are spliced ​​and assembled on-site using the connecting structures 5 at both ends, according to the spacing and position required by the design drawings, to form a reinforcing mesh 1 of predetermined size and shape. The assembled reinforcing mesh 1 is then laid on the surface of the fill material in the current construction layer. If the reinforcing unit 2 is equipped with a positioning mechanism, the movable anchor rod can be driven into a retracted state via a control module to facilitate smooth laying. After laying, the positioning mechanism can be activated to unfold the movable anchor rod and anchor it into the lower fill material, achieving initial fixation of the reinforcing mesh 1. Subsequently, the remaining fill material is spread and covered until the reinforcing mesh 1 is completely embedded in the fill material.

[0077] Once the reinforcing mesh 1 is covered by the filler, the vibration excitation component 6 within the reinforcing unit 2 can be activated via the control module. The vibration excitation component 6 operates according to preset or remotely controlled vibration parameters, and the generated vibrations are directly transmitted to the surrounding filler through the main structure 3 of the reinforcing unit 2 and its anti-slip structure 4. The vibration energy causes relative movement and rearrangement of the filler particles, effectively reducing porosity between particles, thereby achieving an active, deep compaction effect radiating from the interior of the reinforcing mesh 1 to the surrounding area. During this process, some of the vibration energy generated by the vibration excitation component 6 can be recovered by the energy recovery component and converted into electrical energy for storage, used for auxiliary power supply.

[0078] Once the predetermined vibration compaction operation is completed, the control module stops the vibration excitation component 6. At this time, the reinforcing mesh 1 remains inside the high fill. During the subsequent operation of the high fill, the reinforcing mesh 1, with its own tensile strength and the strong mechanical interlocking formed with the fill material by the anti-slip structure 4 and anchoring claws 42, continuously provides tensile and shear reinforcement to the high fill, improving its overall strength and long-term stability. At the same time, the drainage channels and guide grooves opened on the reinforcing unit 2 can perform drainage functions when seepage occurs in the high fill, reducing the pore water pressure at the interface and further ensuring the stability of the strength of the reinforcing interface and the surrounding fill material.

[0079] Furthermore, during the curing or operation phase after the high fill is completed, the vibration assembly 6 can be activated again or intermittently via the control module based on monitoring data such as settlement and consolidation of the high fill, applying low-intensity vibration to the high fill. This subsequent micro-vibration treatment helps accelerate the rheological stabilization process of the fill material, promotes the adjustment and compaction of fine particles, thereby shortening the cycle for the high fill to reach its final stable state.
