Description

Technical Field

[0001] This utility model relates to the field of Yellow River embankment maintenance technology, specifically to a prefabricated road protection pier for Yellow River embankments. Background Technology

[0002] Currently, with the gradual completion of standardized Yellow River embankments and the hardening of embankment roads, the passage of overweight and oversized vehicles poses a significant threat to these roads, often resulting in severe damage. This also brings difficulties and a heavy burden to the management of Yellow River embankment projects. Therefore, a prefabricated road protection pier is needed in the maintenance of Yellow River embankments.

[0003] Chinese patent document CN215104897U discloses a prefabricated road pier for the Yellow River embankment. It incorporates a telescopic rod, a sleeve, a slide rail, a first limiting block, and a first spring. The telescopic rod retracts within the sleeve, making the device more stable during fixation and greatly increasing its ease of use. The device is also more stable during support, improving its overall stability. Furthermore, it includes a locking rod, a locking groove, a fixing groove, a second spring, and a first connecting cylinder. When fixing the mechanism, the locking rod and locking groove engage, further stabilizing the device and enhancing its stability. Finally, it includes a locking head, a locking plate, a third spring, and a second connecting plate. When connecting multiple road pier bodies, the locking head and locking plate engage, fixing and locking the connecting pipes, making the connection and fixation process more stable and significantly increasing the device's stability during use.

[0004] The existing technology has the following problems:

[0005] Currently, most road guardrails are cast directly on both sides of the road, making them inconvenient to assemble and disassemble. This prevents some large emergency vehicles from passing over the guardrails, thus affecting rescue and other work. Furthermore, they do not provide cushioning, and when a vehicle hits a road guardrail, the guardrail will be damaged by a strong impact. Utility Model Content

[0006] This utility model provides a prefabricated road protection pier for the Yellow River embankment to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] A prefabricated retaining wall pier for the Yellow River embankment includes several retaining wall pier bodies. Assembly rods are provided between adjacent retaining wall pier bodies. Buffer grooves are provided on the front and rear sides of each retaining wall pier body. A buffer assembly is slidably connected to the inner cavity of each buffer groove.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figures 1-7 As shown, a prefabricated road pier for the Yellow River embankment includes several road pier bodies 1. Assembly rods 2 are provided between adjacent road pier bodies 1. Buffer grooves 9 are provided on the front and rear sides of each road pier body 1. Buffer components 4 are slidably connected to the inner cavity of the buffer grooves 9. The top of each road pier body 1 is U-shaped. Connecting columns 11 are fixedly installed at the front and rear positions of opposite sides of the top of each road pier body 1. The bottom of each road pier body 1 is conical. Mounting plates 7 are fixedly installed at the four corners of the lower surface of each road pier body 1. The buffer components 4 include buffer plates 41, which are slidably connected to the inner surface of the buffer grooves 9. A damper 43 is fixedly installed on the right side of the buffer plate 41. A spring 44 is movably sleeved on the outer surface of the damper 43. The fixed end of the damper 43 is fixedly installed to the right side of the buffer groove 9. The two ends of the spring 44 are fixedly installed to the right side of the buffer plate 41 and the right side of the buffer groove 9, respectively. There are nine dampers 43 and springs 44, arranged in a linear array.

[0028] The road pier body 1 is symmetrically installed on both sides of the Yellow River embankment using mounting plates 7 and bolts. Adjacent road pier bodies 1 are connected into a whole using assembly rods 2. The road pier bodies 1 and assembly rods 2 are installed on both sides of the embankment according to its length, ensuring vehicles can travel within the designated area, maintaining the integrity of the embankment structure, and improving the safety and emergency passage capacity of the embankment road. The construction process of this prefabricated road pier is relatively simple and convenient, reducing on-site work and construction time, and minimizing the impact on the surrounding environment. During use, when it is necessary to move the road pier body 1, it can be quickly moved using bolts and mounting plates 7. The road pier body 1 was removed from the Yellow River embankment, enabling rapid disassembly and assembly of the road pier body 1. This improved the convenience of using the road pier, allowing large vehicles and special vehicles for embankment maintenance to pass through in a timely manner, ensuring the smooth progress of flood control and disaster relief work. When a vehicle collides with the road pier body 1, the vehicle will first come into contact with the buffer plate 41. With the cooperation of the damper 43 and the spring 44, the buffer plate 41 will have a certain buffering effect on the road pier body 1, thereby preventing the road pier body 1 from being damaged due to strong impact. To a certain extent, it plays a protective role for the road pier body 1 and extends the service life of the road pier.

[0029] like Figures 2-5 As shown, cylindrical positioning grooves 8 are provided on the upper and lower positions of the left and right sides of the road pier body 1, and positioning posts 6 are fixedly installed on the left and right ends of the assembly rod 2. The outer surface of the positioning post 6 is inserted into the inner surface of the positioning groove 8.

[0030] By inserting the positioning post 6 and the positioning groove 8, the assembly rod 2 can be positioned, making the installation of the adjacent road pier body 1 more convenient.

[0031] like Figure 5 As shown, an anti-slip sleeve 3 is fixedly installed on the outer surface of the connecting column 11. The anti-slip sleeve 3 is made of rubber.

[0032] The connecting column 11 facilitates the movement of the road pier body 1, and the anti-slip sleeve 3 can play a role in preventing slipping and improving the convenience of movement. The staff can put their hands on the anti-slip sleeve 3 to facilitate the movement of the road pier body 1.

[0033] like Figures 1-6 As shown, reflective strips 5 are fixedly installed on the upper and lower positions of the front and rear sides of the road pier body 1.

[0034] Setting up reflective strips 5 can improve visibility at night or in poor visibility conditions, thereby increasing driving safety.

[0035] like Figure 6 , Figure 7 As shown, limit blocks 42 are fixedly installed on both the left and right sides of the lower surface of the buffer plate 41, and limit grooves 10 are opened on both the left and right sides of the lower surface of the buffer groove 9. The inner surface of the limit groove 10 is slidably connected to the outer surface of the limit block 42, and both the limit groove 10 and the limit block 42 are T-shaped.

[0036] The sliding of the limiting block 42 and the limiting groove 10 allows the buffer plate 41 to slide within the buffer groove 9, while also limiting the buffer plate 41.

[0037] The working principle of this invention is as follows: The road pier body 1 is symmetrically installed on both sides of the Yellow River embankment using mounting plates 7 and bolts. The positioning post 6 on the assembly rod 2 is inserted into the positioning groove 8 on the road pier body 1. Another road pier body 1 is then installed on the right side of the road pier body 1, with its left positioning groove 8 connected to the positioning post 6 on the right end of the assembly rod 2. The road pier body 1 and assembly rod 2 are installed on both sides of the embankment according to its length, ensuring vehicles can travel within a specified range. The assembly rod 2 and positioning post 6 connect adjacent road pier bodies 1 into a single unit, improving the safety and emergency passage capacity of the embankment road. The construction process of this prefabricated road pier is relatively simple and convenient, reducing on-site work and construction time, and minimizing the impact on the surrounding environment. During the process, when it is necessary to move the main body 1 of the road embankment, the main body 1 of the road embankment can be quickly removed from the Yellow River embankment by means of bolts and mounting plates 7. This enables the rapid disassembly and assembly of the main body 1 of the road embankment, facilitating the timely passage of large vehicles and special vehicles for embankment maintenance and repair, and ensuring the smooth progress of flood control and disaster relief work. The reflective strips 5 can improve visibility at night or in poor visibility conditions, thereby increasing driving safety. When a vehicle crashes into the main body 1 of the road embankment, the vehicle will first come into contact with the buffer plate 41. With the cooperation of the damper 43 and the spring 44, the buffer plate 41 will produce a certain buffering effect on the main body 1 of the road embankment, thereby preventing the main body 1 of the road embankment from being damaged by strong impact. To a certain extent, it plays a protective role for the main body 1 of the road embankment and extends the service life of the road embankment.

[0038] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
