Description

Technical Field

[0001] The utility model relates to the technical field of expressways, in particular to a sound insulation barrier for expressways. Background Art

[0002] Expressways, also known as highways, are roads designed specifically for high-speed motorway travel. The definition of expressways varies across different countries, regions, eras, and academic fields. According to China's "Highway Engineering Technical Standard" (JTGB01-2014), expressways are multi-lane roads designed for motorway travel in separate directions and lanes, with fully controlled access. The average annual daily design traffic volume for expressways should be at least 15,000 passenger vehicles, with a design speed of 80 to 120 kilometers per hour.

[0003] After searching, Chinese patent application No. 202021971991.5 discloses a sound barrier for highways that is easy to adjust. The barrier base includes a barrier base with a groove on its upper surface. A barrier plate is provided above the groove, and a protrusion is installed on the outer wall of the bottom end of the barrier plate. The outer surface of the protrusion is adapted to connect with the inner surface of the groove. A screw is installed on one side of the barrier base, and the screw passes through the barrier base, the groove, and the protrusion and extends into the interior of the barrier base. This utility model is provided with an extension plate. By pulling the pull plate outward, the pull plate is rotated, causing the sliding sleeve and the connecting plate to drive the extension plate to slide, causing the extension plate to slide out of the interior of the barrier plate. This makes it convenient to extend the sound barrier in some noisy sections. At the same time, the noise can be sent to the sound absorbing cabin through the sound absorption port for full absorption, reducing the spread of noise and avoiding the impact of noise on the lives of surrounding residents.

[0004] Although the above patent is provided with an extension plate, the pull plate is rotated by pulling the pull plate outward, so that the sliding sleeve and the connecting plate drive the extension plate to slide, and the extension plate slides out of the barrier plate, which is convenient for lengthening the sound insulation board in some noisy sections. At the same time, the noise can be sent to the sound absorbing cabin through the sound absorption port for full absorption, thereby reducing the spread of noise and avoiding the impact of noise on the lives of surrounding residents. However, in actual use, it is not convenient to install and disassemble the sound insulation barrier. During installation, the sound insulation barrier needs to be transported to the installation site as a whole, which is inconvenient to transport. At the same time, it is not firmly fixed during use and is prone to tipping over when hit or in bad weather, affecting the use effect and bringing inconvenience to the user.

[0005] Therefore, it is necessary to modify it to facilitate the installation and disassembly of the sound insulation barrier, facilitate transportation, fix it firmly, and not easily fall over, which is convenient for users. Utility Model Content
