Abstract
Description
Technical Field
[0001] This application relates to the field of guardrail technology, and more specifically to a resilient highway traffic guardrail that is easy to restore. Background Technology
[0002] Guardrails are one of the safety facilities in traffic engineering. They can be used in the construction of traffic engineering projects such as highways, parking lots, and scenic spots to provide safety protection for vehicles, thereby reducing vehicle accident damage and improving safety protection.
[0003] However, existing highway traffic guardrails not only have drawbacks such as long construction time, difficulty in repairing damaged sections, and untimely repairs, but most of them are also rigid and cannot mitigate the impact of vehicles losing control, resulting in poor safety protection.
[0004] Therefore, the existing guardrails need to be improved. Utility Model Content
[0005] In view of this, this application provides an easily recoverable flexible highway traffic guardrail to solve the technical problems of existing highway traffic guardrails, which not only have the defects of long construction time, difficulty and untimely repair after damage, but also are mostly rigid and cannot mitigate the impact of vehicles losing control, resulting in poor safety protection effect.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] An easily recoverable resilient highway traffic guardrail, comprising:
[0008] Several pillars;
[0009] Flexible protective components are respectively installed on both sides of two adjacent columns;
[0010] The flexible protection component includes:
[0011] External prestressed steel strands connected to one side of two adjacent columns;
[0012] At least one internally prestressed steel strand is connected to the other side of two adjacent columns.
[0013] Furthermore, the flexible protective component also includes several flexible protective nets connected to the inner prestressed steel strands and the outer prestressed steel strands.
[0014] Furthermore, an inner protective element is provided on the outer side of the internally prestressed steel strand.
[0015] Furthermore, the inner protective element includes an inner flexible waterproof sleeve.
[0016] Furthermore, an outer protective element is provided on the outer side of the externally prestressed steel strand.
[0017] Furthermore, the outer protective component includes an outer flexible waterproof sleeve.
[0018] Furthermore, several steel plates are provided on both sides of the column, and both ends of the inner prestressed steel strand and the outer prestressed steel strand are anchored between the two steel plates of two adjacent columns.
[0019] As can be seen from the above technical solution, the advantages of this utility model are:
[0020] 1. In this application, the column is made of steel and fixed to the road surface with bolts, which makes the installation and disassembly of the column convenient and facilitates subsequent replacement work.
[0021] 2. In this application, the flexible protective components are installed on both sides of the column. The inner prestressed steel strands in the flexible protective components can provide a buffer for vehicles on the inner side of the road, and the outer prestressed steel strands in the flexible protective components can provide further protection for the inner prestressed steel strands. Therefore, under the dual protection of the inner and outer prestressed steel strands, the impact mitigation effect can be achieved, thereby enhancing the overall impact resistance of the guardrail.

[0027] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and their descriptions are used to explain this application, but are not intended to limit it.
[0028] refer to Figures 1 to 3 ,like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides an easily recoverable flexible highway traffic guardrail, including: several posts 1 and several flexible protective components. The posts 1 are arranged in a line at intervals on the road. The flexible protective components are located between the inner and outer sides of two adjacent posts 1 (the inner side is the side closer to the middle of the road, and the outer side is the side originally farther from the middle of the road). The flexible protective components can provide flexible protection for vehicles, reducing vehicle damage while reducing the impact on the guardrail itself, thereby extending its service life. Specifically, the flexible protective components include: an outer prestressed steel strand 42, at least one inner prestressed steel strand 41, and several flexible protective nets 6. The inner prestressed steel strand 41 is connected between the inner sides of two adjacent posts 1 by anchoring; the outer prestressed steel strand 42 is also connected to the outer sides of two adjacent posts 1 by anchoring; the flexible protective nets 6 are connected between the inner prestressed steel strand 41 and the outer prestressed steel strand 42.
[0029] Preferably, an inner protective element is provided on the outer side of the internally prestressed steel strand 41.
[0030] Specifically, the inner protective component includes an inner flexible waterproof sleeve 31, which is sleeved on the outside of the inner prestressed steel strand 41. It can provide protection for the inner prestressed steel strand 41 to prevent it from being corroded, thereby extending its service life.
[0031] Preferably, an outer protective element is provided on the outer side of the externally prestressed steel strand 42.
[0032] Specifically, the outer protective component includes an outer flexible waterproof sleeve 32, which is sleeved on the outside of the outer prestressed steel strand 42. It can provide protection for the outer prestressed steel strand 42 to prevent it from being corroded, thereby extending its service life.
[0033] In one embodiment, several steel plates 2 are provided on both sides of the column 1. The two ends of the inner prestressed steel strand 41 and the outer prestressed steel strand 42 are anchored and fixed between two steel plates 2 at corresponding positions on two adjacent columns 1. Specifically, four steel plates 2 are provided on the inner side of the column 1 for fixing two inner prestressed steel strands 41, and two steel plates 2 are provided on the outer side of the column 1 for fixing one outer prestressed steel strand 42.
[0034] like Figure 2 As shown, two inner prestressed steel strands 41 are installed between the inner sides of two adjacent columns 1. The two inner prestressed steel strands 41 and the outer prestressed steel strands 42 located on the outer side of the column 1 are distributed at intervals, so that the upper, middle and lower positions of the guardrail have good impact resistance.
[0035] When a vehicle loses control and crashes into the guardrail due to an accident or malfunction, the flexible protective net 6 connects the inner prestressed steel strands 41 and the outer prestressed steel strands 42. This prevents the inner and outer prestressed steel strands 41 and 42 from becoming unstable and acts as the first line of defense against impact. When the impact is too great and causes excessive deformation of the flexible protective net 6, the inner prestressed steel strands work in conjunction with the two outer prestressed steel strands 42 to act as the second line of defense against impact. Therefore, through the combined action of the inner prestressed steel strands 41, the outer prestressed steel strands 42, and the flexible protective net 6, this application achieves a dual buffering effect, greatly improving the overall impact resistance of the guardrail and reducing the risk of overturning when a vehicle hits the guardrail. The strong buffering capacity also allows the application to easily recover after being subjected to impact, reducing the cost of damage maintenance and replacement.
[0036] In addition, the column 1 is made of steel and is fixed to the road surface with bolts, which not only makes construction convenient and quick, but also makes replacement easy, greatly reducing the difficulty of subsequent maintenance work.
[0037] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to the embodiments of this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
