Description

Technical Field

[0001] The present application relates to the technical field of road safety protection, and in particular to a method for reinforcing a corrugated beam guardrail and a corrugated beam guardrail. Background Art

[0002] The corrugated steel guardrail is a continuous structure made of corrugated steel guardrail panels connected to each other and supported by columns. When a vehicle collides with it, the corrugated steel guardrail panels have good collision resistance and energy absorption, so they are not easily destroyed, and at the same time they can provide good protection for the vehicle and the driver and passengers.

[0003] The four-level corrugated beam guardrail of the prior art is composed of a column 10, a blocking block 20 and a corrugated plate 30, see Figure 1 After the collision of a medium-sized bus, the maximum lateral dynamic displacement extension value W of the guardrail is 1.34m, and the maximum dynamic camber equivalent value VI of the vehicle is 2.27m. The meanings of W and VI are shown in Figure 2 As shown. When structures such as lighting poles, traffic sign poles, bridge piers, etc. are required to be installed on the outside of the guardrail, in order to avoid the vehicle from tilting outward and colliding with the outer structure during the collision with the guardrail, resulting in serious damage to the vehicle and the structure and serious injury to the driver and passengers, the distance between the structure on the outside of the guardrail and the guardrail collision surface shall not be less than 2.27m. Due to the limitation of construction land in my country's expressways, the distance between the lighting poles, traffic sign poles, bridge piers and the guardrail collision surface on the outside of the guardrail of a large number of expressways does not meet this requirement. When the four-level corrugated beam guardrail in the prior art is installed, there are obvious safety hazards for vehicles, drivers and passengers, and roadside structures.

[0004] When adding structures to the outside of the guardrail of an operating highway, it is necessary to strengthen the structure of the corrugated beam guardrail on the corresponding road section to reduce the vehicle camber and guardrail deformation after the vehicle collides with the guardrail. The existing technology often adopts the method of dismantling the original corrugated beam guardrail and replacing it with a guardrail structure with greater strength, stiffness and less deformation. This not only wastes the original corrugated beam guardrail material, but also increases the project cost. Due to the long construction period, it will also have a great impact on the highway traffic operation. Summary of the invention

[0005] The purpose of the embodiments of the present application is to provide a method for strengthening a corrugated beam guardrail that can enhance the collision resistance of a corrugated beam guardrail without dismantling the original corrugated beam guardrail, and a corrugated beam guardrail structure formed by using the method, so as to solve the technical problems of material waste, high project cost, long construction period, etc. in existing corrugated beam guardrail reinforcement implementation methods.

At the same time, the anti-dumping component added to the bottom of the column can also restrain and reduce the roll of the column during a vehicle collision, further increase the overall vertical stiffness of the guardrail, and prevent the column from tipping over to the non-collision-proof side.

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0035] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0036] The inventor of the present application found that in the highway section where there are dangerous structures near the guardrail on the roadside, in order to enhance the rigidity and anti-collision strength of the corrugated beam guardrail in this section, it is necessary to dismantle the original corrugated beam guardrail and replace it with a guardrail structure with greater strength, rigidity and less deformation. This will cause waste of the original corrugated beam guardrail material and increase the project cost. Therefore, the inventor of the present application takes the original corrugated beam guardrail as the starting point, analyzes the parts of the existing corrugated beam guardrail that will be impacted and easily deformed when being collided, and takes corresponding strengthening measures for these parts that are prone to deformation, thereby achieving the strengthening of the entire structure of the corrugated beam guardrail.

[0037] The following is a detailed explanation of how to strengthen the corrugated beam guardrail structure.

[0038] The corrugated beam guardrail described in the present application comprises a column, a first blocking block and a corrugated plate. On the basis of this structure, the corrugated beam guardrail is structurally strengthened. Figure 3 This is a flow chart of a method for strengthening a corrugated beam guardrail according to an embodiment of the present application. Figure 3 The method for strengthening the corrugated beam guardrail includes the following steps.

[0039] S101: A reinforcing beam is arranged on one side of the corrugated plate close to the column, and the reinforcing beam extends along the length direction of the corrugated plate to increase the longitudinal stiffness of the corrugated beam guardrail.

[0040] S102: a second anti-blocking block is provided to connect the reinforcing beam and the column; the first anti-blocking block, the column and the second anti-blocking block form a vertical force-bearing body.

[0041] S103: An anti-tipping component is added to the bottom of the column to prevent the column from tipping over to the non-collision-proof side.

[0042] In the above implementation process, on the basis of the structure provided with a column, a first anti-blocking block and a corrugated plate, a reinforcing beam is added on the side of the corrugated plate of the corrugated beam guardrail close to the column, and the reinforcing beam is fixed to the column through the second anti-blocking block. The reinforcing beam can prevent the vehicle from penetrating the guardrail after a collision, increase the overall longitudinal stiffness of the guardrail, and reduce the vehicle camber and guardrail deformation after the collision. The first anti-blocking block and the second anti-blocking block are fixed to the column and arranged in the vertical direction. When the vehicle collides with the guardrail, the first anti-blocking block, the column and the second anti-blocking block constitute a vertical force-bearing body to support the guardrail to form a reaction force in the vertical direction, thereby increasing the overall vertical stiffness of the guardrail. At the same time, the anti-dumping component added to the bottom of the column can also restrain and reduce the roll of the column during a vehicle collision, further increase the overall vertical stiffness of the guardrail, and prevent the column from tipping over to the non-collision-proof side.

[0043] It can be seen from the above scheme that the method for strengthening the corrugated beam guardrail in this application does not require the replacement of the original corrugated beam guardrail, but rather strengthens the original corrugated beam guardrail in the longitudinal and vertical directions respectively, thereby reducing the vehicle camber and guardrail deformation after the collision, and forming effective protection for the vehicle, driver and passengers, and the outer structure of the guardrail. Therefore, the scheme in this application has the characteristics of on-site processing and convenient construction. At the same time, the corrugated beam guardrail requires less space to play a protective role, which plays a role in saving land for highway construction.

[0044] In a possible implementation, providing a reinforcing beam on a side of the corrugated plate close to the column includes: fixing the reinforcing beam at a middle and lower portion of the corrugated plate.

[0045] When a small vehicle collides, the collision site is usually the front side of the vehicle head. Since the front side of the small vehicle head is located at a lower position, when colliding with the corrugated beam guardrail, the collision position is mostly in the middle and lower part of the corrugated plate. Placing the reinforcement beam in the middle and lower part of the corrugated plate can prevent the small vehicle from passing under the guardrail after the collision, making the guardrail less likely to be damaged.

[0046] In a possible implementation, the bottom end of the reinforcing beam is lower than the bottom end of the corrugated plate by a predetermined height, and the reinforcing beam is detachably connected to the corrugated plate.

[0047] The collision position between small vehicles and corrugated plates is mostly in the middle and lower part of the corrugated plates. The reinforcement beam can prevent small vehicles from passing under the guardrail after collision. However, when the impact force is relatively large, the part of the reinforcement beam extending from the bottom of the guardrail is damaged due to the impact force, while the damage to the corrugated plate is reduced or not damaged. Therefore, the reinforcement beam also has the function of protecting the corrugated plate. At the same time, since the reinforcement beam and the corrugated plate are detachably connected, when the reinforcement beam is damaged and the corrugated plate is slightly damaged, only the reinforcement beam can be replaced and the corrugated plate can be repaired. This setting can effectively reduce the maintenance cost of the corrugated beam guardrail.

[0048] According to another aspect of the present application, a corrugated beam guardrail is also provided. Figure 4 A schematic diagram of the front structure of a corrugated beam guardrail shown in an embodiment of the present application; Figure 5 for Figure 4 The back structure diagram of the corrugated beam guardrail structure is shown. Figure 4 and Figure 5 The corrugated beam guardrail includes a column 100, a first anti-blocking block 200, a corrugated plate 300, a reinforcing beam 400, a second anti-blocking block 500 and an anti-dumping member 600. The column 100 is used to be fixed on the ground. The first anti-blocking block 200 is arranged at the top of the column 100, and the corrugated plate 300 is fixed on the first anti-blocking block 200 and fastened by the corrugated plate-anti-blocking block connecting bolt 210. The reinforcing beam 400 is arranged on the side of the corrugated plate 300 close to the column 100, and the reinforcing beam 400 extends along the length direction of the corrugated plate 300. The second anti-blocking block 500 is used to connect the reinforcing beam 400 and the column 100. The first anti-blocking block 200, the column 100 and the second anti-blocking block 500 form a vertical force-bearing body to support the corrugated plate 300 and the reinforcing beam 400. The anti-dumping member 600 is arranged at the bottom of the column 100 to prevent the column 100 from tipping over to the non-collision-proof side.

[0049] In the above implementation process, the corrugated plate 300 and the reinforcing beam 400 are used to support the longitudinal stiffness of the guardrail as a whole, and the vertical force-bearing body composed of the first anti-blocking block 200, the column 100 and the second anti-blocking block 500 is used to support the vertical stiffness of the guardrail as a whole. The anti-dumping member 600 further increases the vertical stiffness of the guardrail as a whole, preventing the column 100 from tipping over to the non-collision-proof side. Compared with the existing corrugated beam guardrail that is only provided with the column 100, the first anti-blocking block 200 and the corrugated plate 300, the corrugated beam guardrail in the present application is provided with a reinforcing beam 400 on the side of the corrugated plate 300 close to the column 100, and the reinforcing beam 400 is fixed on the column 100 through the second anti-blocking block 500. The reinforcing beam 400 can prevent small vehicles from penetrating the guardrail after collision, increase the longitudinal stiffness of the guardrail as a whole, and reduce the outward tilt of small vehicles and deformation of the guardrail after collision. The second anti-blocking block 500 located in the middle of the column 100 and the anti-dumping member 600 at the bottom of the column 100 make the present application have better vertical rigidity than the existing corrugated beam guardrail, and it is not easy to dump when it is hit. Therefore, the present application strengthens the longitudinal rigidity and vertical rigidity respectively, reduces the outward tilt of small vehicles and the deformation of guardrails after collision, and effectively protects small vehicles, drivers and passengers, and the outer structure of the guardrail; and has the characteristics of on-site processing and convenient construction.

[0050] In a possible implementation, the reinforcing beam 400 is fixed to the lower middle portion of the corrugated plate 300 .

[0051] When a small vehicle collides, the collision site is usually the front side of the front of the vehicle. Since the front side of the front of a small vehicle is located at a lower position, when colliding with the corrugated beam guardrail, the collision site is mostly in the middle and lower part of the corrugated plate 300. Arranging the reinforcing beam 400 in the middle and lower part of the corrugated plate 300 can prevent the small vehicle from passing under the guardrail after the collision, making the guardrail less likely to be damaged.

[0052] In a possible implementation, the bottom end of the reinforcing beam 400 is lower than the bottom end of the corrugated plate 300 by a predetermined height.

[0053] The collision position between a small vehicle and the corrugated plate 300 is mostly in the middle and lower part of the corrugated plate 300. The reinforcing beam 400 can prevent the small vehicle from passing through the guardrail after the collision. However, when the impact force is relatively large, the portion of the reinforcing beam 400 extending from the bottom of the guardrail is damaged due to the impact force, while the corrugated plate 300 is less damaged or not damaged. Therefore, the reinforcing beam 400 also has the function of protecting the corrugated plate 300. At the same time, since the reinforcing beam 400 and the column 100 are detachably connected, when the reinforcing beam 400 is damaged and the corrugated plate 300 is slightly damaged, only the reinforcing beam 400 can be replaced and the corrugated plate 300 can be repaired. This setting can effectively reduce the maintenance cost of the corrugated beam guardrail.

[0054] In a possible implementation, the second anti-blocking block 500 is a hoop structure. The reinforcing beam 400 is a U-shaped beam structure, and the opening of the U-shaped beam structure faces the column 100 side. An inner lining plate 700 is fixed at a position opposite to the column 100, and the inner lining plate 700 is connected to the hoop structure. As one of the implementations, the inner lining plate 700 can be fixed to the reinforcing beam 400 by bolts. It should be noted that the inner lining plate 700 can also be connected to the reinforcing beam 400 by welding or other connection methods.

[0055] In the above implementation process, the second anti-blocking block 500 adopts a clamp structure, which can be directly sleeved on the column 100 for easy installation. The design of the inner lining plate 700 allows the second anti-blocking block 500 to be conveniently connected to the side of the reinforcing beam 400 close to the column 100, avoiding the need to set bolts on the collision surface of the reinforcing beam 400, so as to achieve a better protective effect of the corrugated plate 300. The reinforcing beam 400 adopts a U-shaped beam structure. The cavity surrounded by the U-shaped beam structure and the inner lining plate 700 can play a certain buffering role in the direction perpendicular to the surface of the corrugated plate 300 when the corrugated plate 300 is impacted by a collision, thereby further improving the protective effect of the corrugated plate 300.

[0056] In a possible implementation, the anti-dumping member 600 includes a ground anchor plate 610, a collision side clamp 620, and a non-collision side clamp 630. The ground anchor plate 610 is arranged around the periphery of the bottom of the column 100 and fixed to the ground. In a possible implementation, the ground anchor plate 610 can be in the form of a flange plate structure and fixed to the ground by fastening bolts.

[0057] Bolt holes for inserting bolts are reserved on the impact side clamp 620 and the non-impact side clamp 630. The impact side clamp 620 and the non-impact side clamp 630 are arranged around the bottom of the column 100 and are fixedly connected by bolts after being installed in place. The bottom of the impact side clamp 620 and the non-impact side clamp 630 are welded to the ground anchor plate 610. The ground anchor plate 610 is fixed to the ground by chemical anchor bolts. In a possible implementation, the ground anchor plate 610 can be fixed to the ground by pre-embedded anchor bolts.

[0058] In one embodiment, the ground anchor plate 610 is divided into two butt-jointed plates. The oncoming side clamp 620 is pre-welded to one of the plates, and the non-oncoming side clamp 630 is pre-welded to the other plate. During installation, after the two plates are butt-jointed, the oncoming side clamp 620 and the non-oncoming side clamp 630 are in a state of being enclosed together. After the oncoming side clamp 620 and the non-oncoming side clamp 630 are connected by bolts, the ground anchor plate 610 is fixed to the ground respectively by chemical anchor bolts. This embodiment is suitable for construction scenarios where welding operations on the engineering site are prohibited.

[0059] In a possible implementation, a stiffening rib 640 is welded on the non-collision side clamp 630 .

[0060] In the above implementation process, the stiffening ribs play a role in strengthening the column 100, restraining and reducing the roll of the column 100 during a vehicle collision, and increasing the overall vertical stiffness of the guardrail.

[0061] It can be seen from the above scheme that the corrugated beam guardrail and the corrugated beam guardrail reinforcement method shown in this application respectively strengthen the longitudinal stiffness and vertical stiffness of the existing corrugated beam guardrail, reduce the vehicle camber and guardrail deformation after the collision, and form an effective protection for the vehicle, the driver and the passengers, and the outer structure of the guardrail. This application does not need to dismantle the original corrugated beam guardrail, and can be implemented on the existing corrugated beam guardrail, and has the characteristics of convenient on-site construction. Therefore, this application can solve the technical problems of material waste, high engineering cost, long construction period, etc. in the existing corrugated beam guardrail reinforcement implementation method.
