Description

Technical Field

[0001] This utility model mainly relates to the field of road administration equipment, specifically a highway noise isolation device. Background Technology

[0002] Traffic noise pollution from highways is becoming increasingly prominent as the road network expands. The high traffic volume and speeds along highways result in a wider range of noise impacts. Residents along the routes are increasingly demanding higher environmental quality and are more aware of their rights, leading to a year-on-year increase in complaints about highway traffic noise. Therefore, accelerating the control of highway traffic noise to provide a quiet living environment for residents along the routes and improve citizens' happiness index has become an important issue for ensuring people's livelihood.

[0003] Noise pollution control on highways involves multiple fields, including engineering and traffic management. It encompasses measures such as road surface optimization and speed limit control, as well as key engineering methods like installing soundproofing devices. However, installing soundproofing devices on both sides of highways faces several challenges: First, highways often traverse complex terrains such as mountains, valleys, and farmland, and some sections must avoid existing facilities such as underground pipelines, bridge piers, and high-voltage lines, limiting foundation treatment and construction space and significantly increasing construction difficulty. Second, some sections have scattered residential areas along the route, requiring precise cost-effectiveness calculations for facility construction, making coordination difficult.

[0004] Especially at highway curves, the noise generated by vehicles moving at centrifugal speeds, combined with the sound reflection effect of the curve, has a more significant impact on nearby residents. However, installing soundproofing devices in these areas requires overcoming several additional limitations: on the one hand, it is necessary to strictly ensure driving visibility safety, and the height and position of the device must be precisely matched to the radius of the curve to avoid obstructing the driver's observation of the road surface, roadside signs, and oncoming vehicles; on the other hand, the soundproofing devices on curved sections need to adopt irregular designs, and the splicing accuracy must be precisely controlled during installation to ensure noise reduction effect, making the construction process more complex and increasing the construction period and cost accordingly. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a highway noise isolation device. Its main advantages are: a modular, bent support plate structure with bends; a sound-insulating layer on the outside of the bent support plate structure to block noise generated inside the highway; a height-adjustable connecting structure inside the bent support plate structure to connect with existing guardrails along the highway, allowing the device to be fixedly installed beside the highway for noise isolation; a position-adjustable support connecting column structure at the rear of the bent support plate structure, and a sleeve structure on one side connecting to the support connecting column; and multiple sets of bent support plates connected and secured to the support connecting column structure via the sleeve structure, forming a noise barrier strip along the highway. The bend structure reflects sound, enhancing the noise isolation effect. Furthermore, the flexible connecting structure allows for tight installation at complex curves on the highway, improving the device's applicability. The modular structure allows for flexible selection of installation location and construction length based on actual conditions.

[0006] To achieve the above objectives, this utility model employs the following technical solution: A highway noise isolation device includes a bent support plate.

A telescopic bolt is provided inside the telescopic bolt hole. A telescopic bolt nut is provided inside the telescopic bolt column support frame and is sleeved on the outer circumference of the telescopic bolt and bolted to it. A rotating shaft connecting column sleeve one is fixedly provided at the outer end of the telescopic bolt. A rotating shaft connecting column sleeve two is bolted to the inner side of the rotating shaft connecting column sleeve one.

[0008] Compared with the prior art, the beneficial effects of this utility model are: 1. By setting up a modular bending support plate structure with bending, and further setting a sound insulation layer on the outside of the bending support plate structure to block the noise generated inside the highway, and further setting a connection structure with adjustable height inside the bending support plate structure to connect with the existing guardrail structure on the side of the highway so that the device is fixedly set on the side of the highway to block noise. 2.

Furthermore, the flexible connection structure allows the device to be tightly installed at complex curves of the highway, improving the applicability of the equipment installation. The modular structure allows the device to flexibly select the installation position and construction length according to the actual situation. Attached Figure Description

[0015] Working principle: During installation, the device first places a single bending support plate 1 on the inner side of the railing according to the required installation height. Then, according to the railing height, the pivot seat 5 is installed at the corresponding position of the pivot seat bolt hole 4. Next, the railing connecting frame 6 is fitted onto the outer perimeter of the railing, and then the railing fixing bolt 8 is used to fix the railing connecting frame 6 to the outer perimeter of the railing. In this way, several bending support plates 1 are sequentially installed on the inner side of the railing. Then, by loosening the fixing bolts 13 installed inside a set of bending support plates 1, the fixing groove block 10 can move the pivot connecting column support plate 14 and the pivot connecting column 15 to a certain position. Finally, the pivot connecting column sleeve 25, which is rotatably mounted on the upper part of an adjacent set of bending support plates 1, is fitted onto the pivot connecting column 15 at the corresponding position in that set. The outer perimeter is further fixed by the rotating shaft connecting column sleeve 26, so that the two sides of the bent support plate 1 are connected to each other. By rotating the telescopic bolt nut 24, the telescopic bolt 23 is driven to retract, pulling a set of bent support plates 1 closer to the set of bent support plates 1 connected to it and further abutting, thereby completing the tight connection of the two sides of the bent support plates 1 to prevent noise leakage. By adjusting the position of different rotating shaft connecting columns 15 and the telescopic bolt 23, the angle of different bent support plates 1 can be adjusted to adapt to the installation of railings with different curvatures. After installation, the sound insulation layer 2 isolates the internal noise of the highway and the waterproof layer 3 protects against rain. Furthermore, the bending angle of each bent support plate 1 is coordinated to reflect noise and improve noise reduction capability. The modular structure realizes flexible noise protection settings.
