Technical Field

[0001] This utility model relates to the field of sound barrier technology, specifically to an adjustable highway sound barrier. Background Technology

[0002] Noise barriers, as an effective facility for reducing noise on highways, are widely used in highway construction.

[0003] However, most existing highway noise barriers have fixed structures and cannot be flexibly adjusted according to factors such as noise intensity and terrain conditions in different road sections. In some high-noise sections, the noise reduction effect of fixed-structure noise barriers is limited; while in some low-noise sections, overly heavy noise barriers not only waste materials but also increase construction costs. Furthermore, the installation and maintenance of traditional noise barriers are relatively complex, and once damaged, repairs are difficult and require significant manpower, material resources, and time.

[0004] Therefore, developing a highway sound barrier that is flexibly adjustable, adaptable to different environmental needs, and easy to install and maintain is of significant practical importance. This invention provides an adjustable highway sound barrier that, through its unique structural design, effectively solves the problems existing in the prior art and has broad application prospects and market value.

The inner wall of the vertical positioning frame 1 is movably connected to a first combined barrier 2 and a second combined barrier 3 stacked from bottom to top. The contact ends of the first combined barrier 2 and the second combined barrier 3 are movably connected.

[0028] The first combined barrier 2 includes a positioning plate 4 and a flip plate 5, with one end of the positioning plate 4 and one end of the flip plate 5 hinged together by a connector.

[0029] The top of the positioning plate 4 is provided with an upper receiving groove 8, and the top of the flip plate 5 is fixedly connected with a plug block 9 that is adapted to the upper receiving groove 8. The outer wall of the plug block 9 is movably plugged into the inner wall of the upper receiving groove 8.

[0030] The connecting parts include a shaft 6 and a bushing 7. The shaft 6 is fixedly connected to the side of the upper receiving groove 8 near the top.

[0031] Example 2

[0032] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, the inner wall of the adaptable arc groove 11 is movably connected to the outer wall of the shaft 6. Side docking grooves 10 are provided on the sides of both the positioning plate 4 and the flipping plate 5, and a side docking block 12 adapted to the side docking groove 10 is fixedly connected to the inner wall of the vertical positioning frame 1.

[0033] The side docking block 12 is movably inserted into the inner wall of the side docking groove 10.

[0034] The bottom end of the vertical positioning frame 1 is fixedly connected to a base 13, and the upper surface of the base 13 is provided with fastening bolts 14.

[0035] The working principle of this adjustable highway sound barrier will be explained in detail below.

[0036] like Figure 1-4 As shown, the core of the adjustable highway sound barrier lies in its ingenious structural design to achieve adjustable functionality. The vertical positioning frame 1 serves as the supporting framework for the entire sound barrier, with a first combined barrier 2 and a second combined barrier 3 stacked from bottom to top on its inner wall.
