Description

Technical Field

[0001] This utility model relates to the field of roadbed reinforcement technology, and in particular to a roadbed reinforcement structure for road design. Background Technology

[0002] A roadbed is the foundation of a track or road surface, and is an earthwork structure formed through excavation or filling. The main function of a roadbed is to provide the necessary conditions for the laying of tracks or roads and the operation of trains or vehicles, and to bear the static and dynamic loads of tracks, locomotives, rolling stock, roads, and traffic loads, while transferring and dispersing the loads deep into the foundation.

[0003] However, in existing technologies, in order to ensure the stability of the roadbed in subsequent use, reinforcement supports are generally installed on its slopes. The reinforcement supports are usually fixed to the roadbed with through nails to ensure stable support for the roadbed. The reinforcement of the roadbed requires the installation of multiple reinforcement supports, and each reinforcement support requires multiple through nails for fixation. Since the reinforcement supports and through nails are mostly in a separate state before installation on the roadbed, and the through nails are more numerous than the reinforcement supports, there may be cases where the through nails are missing or omitted, resulting in some reinforcement supports not being able to be stably installed on the roadbed. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of the existing technology: the reinforcement of the roadbed requires the installation of multiple reinforcement brackets, and each reinforcement bracket requires multiple through nails for fixation. Since the reinforcement bracket and the through nails are mostly in a separate state before installation on the roadbed, and the through nails are more numerous than the reinforcement brackets, there may be cases where the through nails are missing or omitted, resulting in some reinforcement brackets being unable to be stably installed on the roadbed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a roadbed reinforcement structure, comprising a roadbed body, wherein reinforcement supports are placed on both sides of the roadbed body, a through hole is formed on the surface of the reinforcement support, and a through nail is inserted through the through hole, the through nail being inserted into the roadbed body, one end of the through nail being fixedly connected to a limiting plate, and a sliding groove is formed on the surface of the through nail, and a blocking block is fixedly connected to the surface of the through hole, the blocking block being slidably connected to the sliding groove.

[0006] In a preferred embodiment, a positioning post is fixedly connected to the lower surface of the reinforcing bracket, and the positioning post is engaged with the roadbed body.

[0007] In a preferred embodiment, the size of the through hole is adapted to the size of the insert pin.

[0008] In a preferred embodiment, one end of the blocking block is fixedly connected to a locking post, and the locking post engages with one end of the sliding groove.

[0009] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0010] This invention, with the help of a sliding groove and a blocking block, restricts the upward movement of the insert pin in the through hole, preventing it from completely detaching from the through hole during upward movement. With the help of a limiting plate, it restricts the downward movement of the insert pin in the through hole, preventing it from completely detaching from the through hole during downward movement. This allows the insert pin to be stably connected to the reinforcing bracket, effectively preventing the situation of missing or incomplete insertion pin removal. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1

[0018] like Figure 1-3As shown, this utility model provides a technical solution: a roadbed reinforcement structure, including a roadbed body 1, with reinforcement supports 2 placed on both sides of the roadbed body 1's slopes. The reinforcement supports 2 are fixed to the slopes of the roadbed body 1 to reinforce it. A through hole is formed on the surface of the reinforcement support 2, and a through-hole 4 is inserted through the through hole. The through-hole 4 is inserted into the roadbed body 1. One end of the through-hole 4 is fixedly connected to a limiting plate 5, which restricts the downward movement of the through-hole 4, preventing it from completely detaching from the through hole. A sliding groove 6 is formed on the surface of the through-hole, and a blocking block 7 is fixedly connected to the surface of the through hole. The blocking block 7 is slidably connected to the sliding groove 6. With the help of the limiting plate 6 and the blocking block 7, the upward movement of the insert pin 4 in the through hole is restricted, preventing it from completely detaching from the through hole during upward movement. With the help of the limiting plate 5, the sliding groove 6 and the blocking block 7, the insert pin 4 can be stably connected to the reinforcing bracket 2, effectively avoiding the situation where the insert pin 4 is missing or not taken. When the reinforcing bracket 2 needs to be reinforced and installed on the slope of the road base 1, the reinforcing bracket 2 is first placed on the slope of the road base 1, so that the surface of the reinforcing bracket 2 is in contact with the surface of the slope of the road base 1. Then, the limiting plate 5 is struck with a hammer to make the insert pin 4 and the sliding groove 6 on it move downward along the blocking block 7 in the through hole, so that the insert pin 4 penetrates into the road base 1. With the cooperation of the insert pin 4 and the limiting plate 5, the reinforcing bracket 2 is fixed on the road base 1.

[0019] Example 2

[0020] like Figure 1-3 As shown, a positioning post 3 is fixedly connected to the lower surface of the reinforcing bracket 2, and the positioning post 3 is engaged with the roadbed body 1. After the reinforcing bracket 2 is placed on the slope of the roadbed body 1, the positioning post 3 is first inserted into the roadbed body 1 to perform a preliminary positioning effect on the reinforcing bracket 2. This effectively reduces the possibility of the reinforcing bracket 2 moving randomly during the process of hitting the limiting plate 5 to make the through pin 4 enter the roadbed body 1, thus affecting the final support effect of the reinforcing bracket 2 on the roadbed body 1. The size of the hole is matched with the size of the through nail 4, which can effectively ensure the stability of the reinforcing bracket 2 fixed on the road base body 1 with the help of the through nail 4 and the limiting plate 5. One end of the blocking block 7 is fixedly connected to the locking post 8, and the locking post 8 is engaged with one end of the slide groove 6. Before the through nail 4 is connected to the road base body 1, the locking post 8 is engaged at the bottom end of the slide groove 6, so that the tip of the through nail 4 can be stably retracted into the through hole for protection, reducing the possibility of damage to the tip of the through nail 4 before use.

[0021] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
