Description

Technical Field

[0001] This utility model relates to the field of slope protection technology, and in particular to a high-strength flexible highway slope protection and reinforcement structure. Background Technology

[0002] According to Chinese Patent No. CN116927216A, a reinforcement structure for ecological protection of highway slopes relates to the field of slope protection technology. To address the problem that fixing nails to plant fiber blankets on slopes are prone to slippage due to natural factors, resulting in poor fixing effectiveness, the structure includes several plant fiber blankets laid on the slope. Adjacent plant fiber blankets overlap, and a water outlet pipe is installed at the overlap. The water outlet pipe is equipped with a fastening component for pressing the plant fiber blankets together. One end of the water outlet pipe is inserted into the slope. This application has the effect of improving the stability between the plant fiber blankets and the slope.

[0003] The aforementioned comparative documents and existing technologies have the following technical problems: Although the existing traditional active protection nets are effective, their tension during installation depends heavily on the experience of the construction personnel, making it difficult to quantify and standardize. At the same time, for complex slopes with uneven surfaces, gaps can easily exist between the netting and the slope, affecting the protective effect. Furthermore, the pretension may change later due to temperature changes or slight settlement. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-strength flexible highway slope protection and reinforcement structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-strength flexible highway slope protection and reinforcement structure, comprising a tensioner body, a drive locking module provided at one end of the tensioner body, a torque indicator module provided on one side of the drive locking module, an elastic buffer module provided at the other end of the tensioner body, and a connecting ring provided at the bottom of one end of the tensioner body.

[0006] Preferably, the top of the drive locking module is provided with a drive head, the bottom of the drive head is provided with a drive shaft, the bottom of the drive shaft is provided with a ratchet, one side of the ratchet is provided with a pawl, the bottom of the ratchet is provided with a pull cable sleeve, and one side of the pull cable sleeve is provided with a connecting hole.

[0007] Preferably, the torque indicator module includes a torque spring, an indicator housing is provided on the outside of the torque spring, and a pointer is provided on the top of the indicator housing.

[0008] Preferably, the elastic buffer module includes disc springs, and the disc spring array is a disc spring group.

[0009] Preferably, the bottom outer side of the drive shaft is provided with an external thread, one side of the pawl is connected to the inner wall of the tensioner body, the inside of the pull cable sleeve is provided with an internal thread, and the internal thread inside the pull cable sleeve is engaged with the external thread on the outside of the drive shaft.

[0010] Preferably, one end of the torque spring is connected to the drive shaft, the other end of the torque spring is connected to the indicator housing, and one end of the pointer is connected to the drive shaft.

[0011] Preferably, a steel wire rope is provided inside the connecting hole, the steel wire rope passes through the connecting hole and connects to the connecting ring, and an elastic buffer module is provided between the connecting hole and the connecting ring.

[0012] Beneficial effects

[0013] This invention employs a drive locking module and a torque indicator module. The torque spring within the torque indicator module converts the torque on the drive shaft within the drive locking module into angular displacement. This angular displacement causes the pointer connected to the drive shaft to deflect relative to the fixed indicator housing. The indicator window has three levels of scale: yellow, green, and red. When the pointer enters the green level, it indicates that the designed torque or preload has been reached. Simultaneously, the ratchet and pawl mechanism achieves one-way locking on the drive shaft: during forward rotation, the pawl jumps with the ratchet; during reverse rotation, it immediately engages and locks, preventing loosening in the reverse direction. This transforms the tensioning process from an experience-based operation to a visual and verifiable calibration operation, significantly reducing insufficient or excessive preload caused by human error. It facilitates rapid on-site acceptance and traceability of construction quality, making it suitable for consistent control in large-scale modular construction. The ratchet mechanical locking provides passive, maintenance-free long-term holding force, eliminating the risk of thread loosening due to vibration or temperature cycling.

[0014] This invention employs an elastic buffer module with a series of disc springs connected in the tension transmission path. During installation, the disc springs are pre-compressed and store elastic potential energy. Upon encountering a short-term impact, the disc springs first compress and absorb most of the impact energy, extending the impact duration and reducing the peak force. When minor settlement or temperature differences cause the mesh surface to loosen, the disc springs release some of their stored energy and rebound, pushing the connecting ring outward to compensate, achieving automatic pullback and tension recovery. This transforms instantaneous high-energy impacts into controllable elastic deformation, reducing the instantaneous peak force borne by the mesh, stitching ropes, and anchors, thereby reducing fatigue damage and the probability of breakage. It achieves passive self-stabilization within the device, reducing the need for manual re-tightening due to settlement or thermal expansion and contraction, significantly reducing maintenance and inspection frequency and long-term operation and maintenance costs. By adjusting the number of disc springs, the stacking method, and the pre-compression amount, customized stiffness or stroke curves can be achieved for different rockfall energies and slope conditions, improving adaptability.

[0015] This invention employs a compact, integrated structure. Functional modules such as the drive, indicator, ratchet, and disc spring are coaxially integrated within a cylindrical housing. Externally, a standard hexagonal interface drives the module, with connecting rings or cable holes at the ends. Modules can be replaced on-site via end caps or locking devices. All functions are achieved through mechanical components, requiring no power supply or electronic sensors. It is battery-free and can operate stably under harsh conditions such as high temperature, low temperature, humidity, and muddy conditions, making it suitable for long-term deployment on slopes and other outdoor locations. Its compact, modular design facilitates mass production, transportation, and rapid on-site replacement, reducing inventory and spare parts management costs. On-site maintenance requires only conventional mechanical tools, minimizing downtime. It can be used as a standardized component in conjunction with modular protection units, facilitating large-scale promotion and engineering implementation. The overall system offers superior cost-effectiveness. Attached Figure Description

One end of the tensioner body 1 is equipped with a drive locking module 2, and one side of the drive locking module 2 is equipped with a torque indicator module 3. The other end of the tensioner body 1 is equipped with an elastic buffer module 4. A connecting ring 5 is located at the bottom of one end of the tensioner body 1. The top of the drive locking module 2 is equipped with a drive head 201, the bottom of the drive head 201 is equipped with a drive shaft 202, the bottom of the drive shaft 202 is equipped with a ratchet 203, one side of the ratchet 203 is equipped with a pawl 204, the bottom of the ratchet 203 is equipped with a cable sleeve 205, and one side of the cable sleeve 205 is equipped with a connecting hole 206. The torque indicator module 3 is... The system includes a torque spring 301, an indicator housing 302 on the outside of the torque spring 301, and a pointer 303 on the top of the indicator housing 302. The tensioner body 1 has a scale window for the torque spring 301 and the pointer 303 to convert the input torque into a visual indication. The one-way locking mechanism composed of the ratchet 203 and the pawl 204 prevents the drive shaft 202 from reversing after pre-tensioning, thereby achieving standardized pre-tensioning and long-term mechanical locking. The elastic buffer module 4 includes disc springs, and the disc spring array is a disc spring group 401. The disc spring group 401 is arranged on the tension path of the tensioner body 1. When subjected to impact, the disc spring group 401 compresses to absorb energy and rebounds after the external force decreases to compensate for slack, thereby achieving... The device features impact buffering and automatic settlement compensation. The bottom outer side of the drive shaft 202 has an external thread. One side of the pawl 204 connects to the inner wall of the tensioner body 1. The inside of the cable sleeve 205 has an internal thread, which mates with the external thread on the outside of the drive shaft 202. One end of the torque spring 301 connects to the drive shaft 202, and the other end connects to the indicator housing 302. One end of the pointer 303 connects to the drive shaft 202. A steel wire rope 6 is installed inside the connecting hole 206, passing through the connecting hole 206 and connecting to the connecting ring 5. An elastic buffer module 4 is provided between the connecting hole 206 and the connecting ring 5. The tensioner body 1 is cylindrical. The device features an integrated mechanical structure with a coaxial drive, torque indicator, ratchet 203 locking mechanism, and disc spring buffer module. It contains no power supply or electronic components, facilitating long-term field use and on-site maintenance and replacement. Located between the anchor bolts and anchor plates and the top of the protective netting, the device converts the applied torque into controllable axial tension via the drive shaft 202 and threaded sleeve during construction. The torque spring 301 and pointer 303 provide visual pre-tensioning, while the ratchet 203 and pawl 204 mechanically lock and maintain tension. The disc spring assembly 401 at the end of the tension path compresses and absorbs energy during rockfall impacts and automatically compensates for netting relaxation. This overall design achieves visual pre-tensioning, long-term force holding, and adaptive buffering, improving protective stability and reducing maintenance frequency. Specific Implementation Example 2:

[0027] Reference Figure 1The device is equipped with a drive screw and nut sleeve, a mechanical pull wire indicator, a differential clutch mechanism, a double-chamber gas spring buffer unit, a safety shear pin or overflow limiter, a housing and connecting ring 5. A linear scale directly displays the axial displacement of the sleeve and the corresponding tension, facilitating construction acceptance and recording. Short-term impacts are mitigated by the gas spring. The air chamber pressure and spring work together to achieve passive compensation for impact energy absorption and mesh relaxation. When the set torque is exceeded, the differential clutch allows slight slippage or triggers the shear pin to prevent instantaneous damage to structural load-bearing components and clearly indicates the need for maintenance. It features a fully mechanical or pneumatic hybrid design, requires no power supply, and allows for quick replacement of key components. It is suitable for batch construction and harsh environments. By adjusting the air pressure, spring stiffness, and differential torque, buffering and compensation characteristics can be customized for different rockfall energies and slope conditions.
