Description

Technical Field

[0001] This utility model belongs to the field of corrugated beam guardrail posts, and in particular relates to a corrugated beam guardrail post designed to control the burial depth. Background Technology

[0002] Corrugated beam guardrails are movable steel guardrails installed in the median strip or along the sides of highways to isolate the road and protect vehicles and passengers. They consist of corrugated steel guardrail panels and posts. The posts, as the main fixed support components between the guardrail and the ground, are buried to a depth that determines their stability. The post burial depth is a crucial indicator for the construction quality inspection of highway corrugated beam guardrails; insufficient burial depth can pose safety hazards to drivers. In traffic accidents resulting in injuries or fatalities, the burial depth of the guardrail posts at the accident site is frequently included in the accident investigation. Due to the large number of guardrail posts, project quality managers cannot guarantee the proper management of each post's construction process. Construction workers may be negligent, using incorrect post lengths or intentionally cutting posts for convenience, creating potential risks for project quality managers.

[0003] According to the "Highway Engineering Quality Inspection and Evaluation Standard, Volume 1: Civil Engineering" (JTG F80 / 1-2017), the testing frequency for post burial depth is 5 measurements per side per 1 km. Currently, the quality inspection of post burial depth often involves pulling out the post for measurement or using a depth measuring instrument. The pull-out measurement method yields accurate results, but it is a destructive test; while using a depth measuring instrument is more convenient, but the accuracy of the results is not ideal. Utility Model Content

[0004] The purpose of this utility model is to provide a corrugated beam guardrail post designed to control the embedment depth, in order to solve the current problems where, due to the large number of guardrail posts, project quality managers find it difficult to ensure that the construction process of each post is properly managed. Construction workers may be negligent and use the wrong post length or deliberately cut the post for ease of construction, which poses a potential risk to project quality managers. In the quality inspection of post embedment depth, the common methods are to pull out the post for measurement or to use a depth measuring instrument to measure the post embedment depth. The pull-out measurement method is accurate, but it is a destructive test; while the depth measuring instrument is more convenient, the results are less accurate.

[0005] To achieve the above objectives, the specific technical solution of this utility model for a corrugated beam guardrail post designed to control the burial depth is as follows:

[0006] A corrugated beam guardrail post designed to control burial depth includes a post body; the post body has a hollow column structure; a metal closed tube is fixedly installed on the inner wall of the post body; a transparent tube is fixedly installed between the metal closed tube and the post body; a display window is provided in the middle of the metal closed tube relative to the transparent tube; a colored liquid is filled in the transparent tube; and a scale is vertically installed on one side of the metal closed tube and the transparent tube.

[0007] Furthermore, the metal enclosed tube can be optionally installed on the outer wall of the column body.

[0008] Furthermore, the lower end of the metal enclosed tube gradually sloping upwards after it is attached to the main body of the column.

[0009] Furthermore, the lower end of the metal enclosed tube is attached to the main body of the column for 50-100mm, and the sloping raised section is 100-150mm.

[0010] This utility model discloses a corrugated beam guardrail post designed to control the embedment depth, which has the following advantages: By installing a metal enclosed tube inside the post body, and by attaching a scale to the metal enclosed tube, the embedment depth can be calculated by comparing the scale during construction and installation, facilitating the control and inspection of the post body's embedment depth. Construction personnel can quickly and intuitively determine whether the post body is properly inserted, preventing the use of incorrect post body length. Furthermore, by installing a transparent tube inside the metal enclosed tube, and filling the transparent tube with a colored liquid, the colored liquid inside the transparent tube can be observed through a display window on the metal enclosed tube. If the post is cut off during construction, the colored liquid in the metal enclosed tube and the transparent tube will automatically flow out, and the metal enclosed tube... If the closed or transparent tube breaks, it is difficult to restore the seal and refill with colored liquid, resulting in the inability to see the colored liquid in the display window. Quality management and inspection personnel can easily determine whether the column has been cut off by checking for the presence of colored liquid. After understanding this function, construction personnel will consciously avoid deliberately cutting off the column for convenience during construction. The lower end of the metal sealing tube is set to fit the column body for 50-100mm, and the last 100-150mm is gradually raised in a sloping shape. This gradually raised shape effectively reduces the resistance of the metal sealing tube to the column body when it is buried in the ground, reduces the impact of the metal sealing tube on the insertion of the column body, and increases the convenience of the device's installation.

[0017] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a corrugated beam guardrail post designed to control the embedment depth.

[0018] like Figure 1-5 As shown, this utility model discloses a corrugated beam guardrail post designed to control the burial depth, comprising a post body 1; the post body 1 has a hollow column structure; a metal closed tube 2 is fixedly installed on the inner wall of the post body 1; a transparent tube 3 is fixedly installed between the metal closed tube 2 and the post body 1; a display window 4 is provided in the middle of the metal closed tube 2 relative to the transparent tube 3; a colored liquid 5 is filled in the transparent tube 3; and a scale 6 is vertically installed on one side of the metal closed tube 2 and the transparent tube 3.

[0019] Combination Figure 1-5 As shown, when using this corrugated beam guardrail post, the post body 1 is driven into the designated position. The embedment depth is judged by the scale 6 set on the metal enclosed tube 2 on the post body 1. Driving is stopped after the stable depth of the post body 1 is reached. Corrugated beam guardrails are then connected and installed on multiple post bodies 1. During construction and installation, the embedment depth is calculated by comparing with the scale 6, which facilitates the control and inspection of the embedment depth of the post body 1. Construction personnel can quickly and intuitively judge whether the post body 1 is driven into place, preventing the use of the wrong length of post body 1. A transparent tube 3 is set inside the metal enclosed tube 2 to allow for the viewing of the post body. The exposed pipe 3 is filled with colored liquid 5. The colored liquid 5 inside the transparent pipe 3 can be observed through the display window 4 set on the metal sealed pipe 2. If the column is cut off during construction, the colored liquid in the metal sealed pipe 2 and the transparent pipe 3 will automatically flow out. Moreover, it is difficult to restore the seal and refill the colored liquid 5 after the metal sealed pipe 2 and the transparent pipe 3 are broken, so the colored liquid will not be visible in the display window 4. Quality management and inspection personnel can easily determine whether the column has been cut off by the presence of colored liquid 5. After the construction personnel understand this function, they will consciously eliminate the phenomenon of deliberately cutting off the column for convenience during construction.

[0020] The metal sealing tube 2 can be optionally installed on the outer wall of the column body 1. The metal sealing tube 2, the transparent tube 3 and the colored liquid 5 filled in the transparent tube 3 are installed on the outer wall of the column body 1. This makes it easier to observe the scale 6 to distinguish the embedment depth and to identify whether the transparent tube 3 contains the colored liquid 5 when it is being installed or the insertion depth is being checked.

[0021] The lower end of the metal sealing tube 2 is attached to the column body 1 and then gradually rises in a sloping shape. The section of the lower end of the metal sealing tube 2 that is attached to the column body 1 is 50-100mm, and the sloping ...
