Abstract

The utility model discloses a roadside wave-shaped beam guardrail structure for highway engineering. The roadside wave-shaped beam guardrail structure comprises stand columns, anti-blocking blocks and wave-shaped beams. The anti-blocking block is provided with an arc-shaped end face and a flat end face, the left side and the right side of the anti-blocking block protrude outwards, connecting holes are formed in the two end faces of the anti-blocking block, and the arc-shaped end face is used for being fixedly connected through a bolt fixing assembly after being attached to the stand column, so that the anti-blocking block can be connected with the wave-shaped beam and the stand column to form a more stable and more attached overall structure. When a vehicle collides with the guardrail, impact force borne by the wave-shaped beams can be evenly transmitted to the stand columns, the wave-shaped beams are prevented from being deformed or damaged due to overlarge local stress, and therefore the overall impact resistance of the guardrail is improved, and the protection effect is better achieved; due to the fact that the left side and the right side of the blocking block protrude outwards and are hollow, at the moment that a vehicle collides with the guardrail, the constructed blocking block can absorb and dissipate part of impact energy of the vehicle through deformation and displacement of the blocking block, and the buffering effect is achieved.

Description

Technical Field

[0001] This utility model relates to the field of highway engineering implementation, specifically to a roadside corrugated beam guardrail structure for highway engineering. Background Technology

[0002] In the field of highway engineering, roadside corrugated beam guardrails are crucial facilities for ensuring traffic safety, and their performance directly affects driving safety and road utilization efficiency. However, traditional roadside corrugated beam guardrails have revealed many problems that urgently need to be addressed in practical applications. Regarding structural stability and protective performance, early guardrail structures featured simple connections between the corrugated beams and posts, lacking effective buffering and force transmission mechanisms. When a vehicle collides, the impact force is difficult to distribute evenly, causing the corrugated beams to easily deform or even break due to excessive localized stress. This prevents them from fully fulfilling their role in blocking and guiding vehicles, significantly increasing the risk of vehicles running off the road and seriously threatening driving safety. Furthermore, ordinary anti-collision block designs cannot effectively absorb and dissipate the impact energy of vehicles at the moment of collision, failing to provide adequate protection for vehicles and occupants.

[0003] Regarding anti-theft and anti-loosening measures, the traditional bolt connection method for guardrails is basically ineffective at preventing theft. Nuts can be maliciously removed, damaging the structural integrity of the guardrail and rendering its protective function ineffective. At the same time, the continuous vibration generated by vehicles often causes the nuts to loosen, resulting in loose connections between components, reducing the reliability of the guardrail in daily use, and increasing maintenance costs and safety hazards.

[0004] From a visibility perspective, traditional guardrails are difficult for drivers to see clearly at night or in low-light conditions. The lack of effective reflective markings on the posts makes it difficult for drivers to accurately judge the position of the guardrails and the road boundaries in a timely manner. In complex road sections such as curves, slopes, and intersections, collisions caused by poor visibility are common.

[0005] Regarding compatibility with the roadbed, some guardrail posts suffer from simplistic and ineffective fixing methods. For example, simply burying the posts at a shallow depth in the roadbed without effective reinforcement measures makes them prone to loosening and toppling under significant external impacts, failing to provide stable support for the guardrail. Furthermore, traditional roadbed structure designs do not adequately consider their synergistic effect with the guardrail, resulting in deficiencies in load-bearing capacity, drainage, and stress absorption across various structural layers, thus impacting the overall service life and performance of both the road and the guardrail. Utility Model Content

[0006] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides a roadside corrugated beam guardrail structure for highway engineering, which is a new guardrail solution that improves stability, provides excellent protection, has anti-theft and anti-loosening functions in corresponding positions, has good visibility, and is well adapted to the roadbed.

[0007] This utility model is implemented as follows: A roadside corrugated beam guardrail structure for highway engineering is constructed, characterized by comprising posts, anti-blocking blocks, and corrugated beams. The anti-blocking blocks have arc-shaped and flat end faces, with outward protrusions on both sides. Connecting holes are opened on both end faces of the anti-blocking blocks. The arc-shaped end faces are used to fit against the posts, and then a bolt fixing assembly is used for fixed connection. The corrugated beam is fixedly connected to the anti-blocking blocks via the bolt assembly. This allows the anti-blocking blocks to connect the corrugated beams and posts, forming a more stable and closely fitting overall structure. When a vehicle collides with the guardrail, it can evenly transfer the impact force on the corrugated beams to the posts, preventing deformation or damage to the corrugated beams due to excessive local stress, thereby improving the overall impact resistance of the guardrail and better fulfilling its protective function. Because the anti-blocking blocks have outward protrusions on both sides and are hollow inside, at the moment of vehicle collision, the constructed anti-blocking blocks can absorb and dissipate some of the vehicle's impact energy through their own deformation and displacement, playing a buffering role. This helps to reduce the degree of vehicle damage and reduce injuries to occupants.

[0008] According to the roadside corrugated beam guardrail structure of this utility model, the corrugated beam is corrugated in shape, with a fixing connection hole in its groove for fixed connection with the anti-blocking block; a curved double-ended screw is provided in the back cavity of the corrugated beam; a reinforcing connection hole for inserting the curved double-ended screw is provided on the waist side of the corrugated beam; both ends of the curved double-ended screw are threaded, and both ends are inserted into the adjacent reinforcing connection holes of the corrugated beam and then fixed by nuts; the curved double-ended screw in the back cavity of the corrugated beam can further form the corrugated beam into a whole, and at the same time further enhance the strength of the corrugated beam itself and the overall stability.

[0009] According to the roadside corrugated beam guardrail structure of the present utility model, the bolt fixing assembly includes a long bolt, an anti-theft clamping nut A, and an inner nut A; the anti-theft clamping nut A is sleeved on the end of the long bolt, the inner nut A is tightened on the end of the long bolt, and the anti-theft clamping nut A can completely cover the inner nut A.

[0010] According to the roadside corrugated beam guardrail structure of the present invention, the bolt assembly comprises a fixing bolt, an anti-theft clamping nut B, an inner nut B, and a washer, wherein the anti-theft clamping nut B can completely cover the inner nut B; a crossbeam washer is also provided between the corrugated beam and the fixing bolt.

[0011] The roadside corrugated beam guardrail structure for highway engineering described in this utility model is characterized in that: the surface of the post is covered with a reflective film.

[0012] According to the roadside corrugated beam guardrail structure of this utility model, the feature is that the lower end of the post is directly driven into the roadbed to a depth of 140cm by drilling, and M20 cement mortar is poured in to fix it. The roadbed consists of, from bottom to top, a 15cm graded crushed stone cushion layer, a 33cm suspended dense cement-stabilized crushed stone subbase, a 20cm skeleton dense cement-stabilized crushed stone base, a 1cm AR-SAMT rubber asphalt stress-absorbing layer, and a 12cm asphalt concrete surface layer.

[0013] This application has many significant beneficial effects. This utility model provides a roadside corrugated beam guardrail structure for highway engineering, which has the following advantages;

[0014] First, this application comprises a column, a guardrail block, and a corrugated beam. The guardrail block has an arc-shaped end face and a flat end face. The left and right sides of the guardrail block protrude outwards, and both end faces of the guardrail block have connection holes. The arc-shaped end face is used to fit against the column, and then a bolt fixing assembly is used for fixed connection. The corrugated beam is fixedly connected to the guardrail block via the bolt assembly. This allows the guardrail block to connect the corrugated beam and the column, forming a more stable and closely fitting overall structure. When a vehicle collides with the guardrail, it can evenly transfer the impact force on the corrugated beam to the column, preventing the corrugated beam from deforming or being damaged due to excessive local stress, thereby improving the overall impact resistance of the guardrail and better fulfilling its protective function. Because the left and right sides of the guardrail block protrude outwards and the interior is hollow, at the moment of vehicle collision with the guardrail, the constructed guardrail block can absorb and dissipate a portion of the vehicle's impact energy through its own deformation and displacement, playing a buffering role. This helps to reduce the degree of damage to the vehicle and reduce the injury to the occupants. The aforementioned anti-collision block can also fine-tune the height of the corrugated beam according to different road surface heights, column heights, and installation requirements, ensuring that the corrugated beam is installed at a suitable height to better adapt to the force conditions during vehicle collisions and improve the protective effect. The presence of the anti-collision block also makes the connection between the corrugated beam and the column more convenient and quick, allowing for accurate positioning of the corrugated beam during installation and reducing installation errors.

[0015] Second, in this application; such as Figure 1 and Figure 8 The corrugated beam is corrugated in shape, and its groove has a fixing connection hole for fixed connection with the anti-blocking block. A curved double-ended screw is set in the back cavity of the corrugated beam. The waist side of the corrugated beam has a reinforcing connection hole for inserting the curved double-ended screw. The curved double-ended screw has threads at both ends, and the two ends are inserted into the adjacent reinforcing connection holes of the corrugated beam and then fixed by nuts. The curved double-ended screw in the back cavity of the corrugated beam can further form the corrugated beam into a whole, and at the same time further enhance the strength of the corrugated beam itself and the overall stability.

[0016] Third, in this application; such as Figure 10 The bolt fixing assembly includes a long bolt, an anti-theft clamping nut A, and an inner nut A; the anti-theft clamping nut A is sleeved on the end of the long bolt, the inner nut A is tightened on the end of the long bolt 4-1, and the anti-theft clamping nut A can completely cover the inner nut A.

[0017] In this application; as Figure 11 The bolt assembly comprises a fixing bolt, an anti-theft clamping nut B, an inner nut B, and a washer. The anti-theft clamping nut B can completely cover the inner nut B. A crossbeam washer is also provided between the corrugated beam and the fixing bolt.

[0018] Fifth, the advantages and functions of setting crossbeam shims in this application are:

[0019] Protecting the Corrugated Beam: The crossbeam shim, placed between the corrugated beam and the fixing bolts, acts as an isolation and buffer. When tightening the fixing bolts, the crossbeam shim prevents the bolt heads from directly contacting the surface of the corrugated beam, preventing scratches or deformation caused by excessive bolt tightening force. This protects the surface quality and structural integrity of the corrugated beam, ensuring it maintains good appearance and performance. Enhancing Connection Stability: The crossbeam shim also fills any small gaps that may exist between the corrugated beam and the bolts, making the connection tighter. When a vehicle collides with the guardrail, it helps to better transmit and disperse impact force, allowing the connection between the corrugated beam and the bolts to bear external force more evenly. This enhances the stability of the entire connection and improves the reliability and protective capability of the corrugated beam guardrail upon impact.

[0020] Sixth, in this application, the surface of the pillar is covered with reflective film. Applying reflective film has the following important functions: improving nighttime visibility, enhancing warning effects, improving road safety, and facilitating maintenance and management.

[0030] The following will be combined with the appendix Figures 1-12 This utility model will be described in detail, and the technical solutions in the embodiments of this utility model will be clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0031] This utility model provides a roadside corrugated beam guardrail structure for highway engineering, such as... Figures 1-12 As shown, it can be implemented as follows: including a column 1, a baffle block 2, and a corrugated beam 3; the baffle block 2 has an arc-shaped end face 2-1 and a flat end face 2-2, and the left and right sides of the baffle block 2 are outwardly protruding 2-3. Both ends of the baffle block 2 have connecting holes. The arc-shaped end face 2-1 is used to fit with the column 1 and then be fixedly connected by bolt fixing assembly 4. The corrugated beam 3 is fixedly connected to the baffle block 2 by bolt assembly 5; so that the baffle block 2 can connect the corrugated beam 3 and the column 1 to form a more stable and fit overall structure. When a vehicle collides with the guardrail, it can evenly transfer the impact force on the corrugated beam to the column, avoiding deformation or damage to the corrugated beam due to excessive local stress, thereby improving the overall impact resistance of the guardrail and better playing its protective role; since the left and right sides of the baffle block 2 are outwardly protruding 2-3 and hollow inside, at the moment of vehicle collision with the guardrail, the constructed baffle block can absorb and dissipate part of the impact energy of the vehicle through its own deformation and displacement, playing a buffering role. This helps reduce the extent of vehicle damage and minimize injuries to occupants. The constructed anti-collision block can also fine-tune the height of the corrugated beam according to different road surface heights, post heights, and installation requirements, ensuring the beam is installed at the appropriate height to better adapt to the forces exerted during a vehicle collision and improve protective effectiveness. The anti-collision block also facilitates faster and more convenient connection between the corrugated beam and the post, allowing for accurate beam positioning during installation and reducing installation errors. Furthermore, when the guardrail requires repair or replacement, the anti-collision block facilitates the disassembly and replacement of relevant parts, reducing maintenance costs and complexity.

[0032] During the implementation of the roadside corrugated beam guardrail structure described in this application; if Figure 1 and Figure 8 The corrugated beam 3 is corrugated in shape, and its groove has a fixing connection hole 3-1 for fixed connection with the anti-blocking block 2. A curved double-ended screw 6 is set in the back cavity of the corrugated beam. The waist side of the corrugated beam 3 has a reinforcing connection hole 3-2 for inserting the curved double-ended screw 6. The curved double-ended screw 6 has threads at both ends, and the two ends are respectively inserted into the adjacent reinforcing connection holes 3-2 of the corrugated beam 3 and then fixed by the nuts 7. The curved double-ended screw 6 in the back cavity of the corrugated beam can further form the corrugated beam 3 into a whole, and at the same time further enhance the strength of the corrugated beam 3 and the overall stability.

[0033] During the implementation of the roadside corrugated beam guardrail structure described in this application; if Figure 10 The bolt fixing assembly 4 includes a long bolt 4-1, an anti-theft clamping nut A4-2, and an inner nut A4-3; the anti-theft clamping nut A4-2 is sleeved on the end of the long bolt 4-1, and the inner nut A4-3 is tightened on the end of the long bolt 4-1, and the anti-theft clamping nut A4-2 can completely cover the inner nut A4-3.

[0034] During the implementation of the roadside corrugated beam guardrail structure described in this application; if Figure 11 The bolt assembly 5 comprises a fixing bolt 5-1, an anti-theft clamping nut B5-2, an inner nut B5-3, and a washer 5-4. The anti-theft clamping nut B5-2 can completely cover the inner nut B5-3. A crossbeam washer 8 is also provided between the corrugated beam 3 and the fixing bolt 5-1.

[0035] For bolt fixing components 4 and 5, the advantages and functions of each bolt component are as follows: Taking bolt component 5 as an example, the position of the anti-theft clamping nut B5-2 can prevent unauthorized disassembly. Its unique design allows it to completely cover the inner nut B5-3, making it difficult for ordinary tools to directly access the inner nut B5-3, greatly increasing the difficulty of illegal disassembly, effectively protecting the integrity of the corrugated beam guardrail, reducing the risk of guardrail failure due to bolt removal, and ensuring road traffic safety. During vehicle operation, the guardrail will be subjected to continuous vibration and impact. The anti-theft clamping nut B5-2, in conjunction with the inner nut B5-3, can provide stronger anti-loosening capability. By applying additional clamping force to the entire nut connection, it reduces the possibility of nut loosening due to vibration, ensuring the long-term stability of the bolt connection, and enabling the guardrail to function reliably in various complex environments.

[0036] The inner nut B5-3 engages with the fixing bolt 5-1 through a threaded connection, achieving initial tightening of the connecting components. Working in conjunction with the anti-theft clamping nut B5-2, the tightening process generates a strong axial force, firmly fixing the connecting components together, ensuring the robustness of the connection, and ensuring that the corrugated beam guardrail does not experience relative displacement between components when subjected to external forces such as vehicle collisions, thus maintaining the stability of the overall structure.

[0037] The advantages and functions of setting the crossbeam shim 8 in this application are:

[0038] Protecting the corrugated beam: The crossbeam shim 8 is placed between the corrugated beam 3 and the fixing bolt 5-1, serving as an isolation and buffer. When the fixing bolt 5-1 is tightened, the crossbeam shim prevents the head of the fixing bolt from directly contacting the surface of the corrugated beam, preventing scratches or deformation caused by excessive bolt tightening force. This protects the surface quality and structural integrity of the corrugated beam, ensuring that it maintains good appearance and performance. Enhancing connection stability: The crossbeam shim also fills any small gaps that may exist between the corrugated beam and the bolt, making the connection tighter. When a vehicle collides with the guardrail, it helps to better transmit and disperse the impact force, allowing the connection between the corrugated beam and the bolt to bear the external force more evenly, thereby enhancing the stability of the entire connection and improving the reliability and protective capability of the corrugated beam guardrail when subjected to impact.

[0039] During the implementation of the roadside corrugated beam guardrail structure described in this application; if Figure 3 As shown, a reflective film 9 is attached to the surface of the column 1. The reflective film 9 serves the following important functions:

[0040] Improved nighttime visibility: Reflective film can reflect vehicle lights back at night or in low light conditions, allowing drivers to clearly see the position and outline of the guardrail, which helps guide drivers to drive correctly and reduces collisions caused by poor visibility.

[0041] Enhanced warning effect: Even during the day, reflective film can enhance the visual effect of the posts, making the guardrail more eye-catching, attracting the driver's attention, and serving as a warning to remind the driver to pay attention to road boundaries and potential dangers, so as to take preventive measures in advance.

[0042] Enhancing road safety: By improving the visibility and warning effect of guardrails, reflective film helps reduce the incidence of traffic accidents, especially on dangerous road sections such as curves, slopes, and intersections, effectively protecting the safety of pedestrians and vehicles.

[0043] Facilitates maintenance and management: When carrying out road maintenance and management, the posts covered with reflective film are easier for staff to identify and locate, making it easier to carry out inspection, repair and maintenance work, thus improving work efficiency.

[0044] During the implementation of the roadside corrugated beam guardrail structure described in this application; if Figure 9 As shown, the lower end of the column 1 is driven directly into the roadbed to a depth of 140cm through drilling, and then fixed with M20 cement mortar. The roadbed consists of, from bottom to top, a 15cm graded crushed stone subbase, a 33cm suspended dense cement-stabilized crushed stone base course, a 20cm skeletonized dense cement-stabilized crushed stone base course, a 1cm AR-SAMT rubber asphalt stress-absorbing layer, and a 12cm asphalt concrete surface course. The advantages and functions of the above column fixing method are:

[0045] (1) Strong anchoring force and stability: The lower end of post 1 is driven directly into the roadbed to a depth of 140cm and fixed with M20 cement mortar, which can provide extremely strong anchoring force for the corrugated beam guardrail. When facing the impact of vehicle collision, such deep embedding and tight wrapping with cement mortar can effectively prevent the post from tilting or shifting, ensuring the overall stability of the guardrail structure, thereby giving full play to its blocking and guiding role for vehicles, greatly reducing the risk of vehicles running off the road due to collision, and ensuring driving safety.

[0046] (2) Good durability: M20 cement mortar has high strength and bonding performance. It can not only fill the gap between the post and the roadbed borehole, but also form a tight bond with the post and the roadbed. This tight bond can effectively isolate the post from external moisture, air and corrosive substances, significantly extend the service life of the post, and reduce the cost and workload of frequent repair or replacement due to post damage.

[0047] The advantages and functions of the aforementioned roadbed structure design are:

[0048] (1) Graded crushed stone cushion layer (15cm)

[0049] Drainage and load-bearing transition: The graded crushed stone subbase effectively drains water from the roadbed, preventing moisture accumulation and thus avoiding problems such as softening and reduced strength caused by water accumulation. Simultaneously, it acts as a load-bearing transition layer, evenly distributing vehicle loads from the road surface to the underlying soil, relieving pressure directly on the soil and improving the overall load-bearing capacity of the roadbed.

[0050] (2) Suspended dense cement-stabilized crushed stone subbase (33cm)

[0051] Enhancing base course stability: The suspended dense cement-stabilized crushed stone subbase possesses high compressive strength and stability. The cement's cementing effect tightly binds the crushed stone together, forming a robust, integrated structure. This layer can withstand significant vehicle loads and distribute them evenly to the base course, effectively reducing pavement deformation and settlement, and ensuring pavement smoothness and driving comfort.

[0052] (3) Dense-frame cement-stabilized crushed stone base course (20cm)

[0053] Providing high load-bearing capacity: The structural characteristics of the dense-skeleton cement-stabilized crushed stone base course give it superior mechanical properties. Its internal skeleton structure provides strong compressive and shear strength, capable of withstanding the heavy loads generated during vehicle traffic. It is the main load-bearing layer in the pavement structure, playing a crucial role in ensuring the long-term performance and durability of the road.

[0054] (4) AR-SAMT rubber asphalt stress-absorbing layer (1cm)

[0055] Stress Absorption and Prevention of Reflective Cracks: AR-SAMT rubber asphalt stress-absorbing layer has excellent flexibility and adhesion. It can effectively absorb and disperse stress generated by factors such as vehicle load and temperature changes in the pavement structure, preventing base layer cracks from reflecting upwards to the asphalt concrete surface layer, thereby extending the service life of the asphalt concrete surface layer, reducing the occurrence of pavement cracks, and improving the overall quality and driving performance of the pavement.

[0056] (5) Asphalt concrete surface layer (12cm)

[0057] Providing a superior driving surface: Asphalt concrete pavements offer excellent properties such as smoothness, wear resistance, and anti-skid properties. A smooth surface reduces drag, improving vehicle speed and fuel economy; wear resistance withstands long-term tire wear, extending the pavement's lifespan; and anti-skid properties ensure good vehicle stability in various weather conditions, providing a safe and reliable driving environment. Furthermore, asphalt concrete pavements also have good noise reduction properties, minimizing noise pollution generated during vehicle operation.

[0058] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
