Description

Technical Field

[0001] The utility model relates to the technical field of bridges, in particular to a bridge anti-noise installation structure. Background Art

[0002] Bridges generally use sound insulation screens to isolate the noise from running vehicles. Sound insulation screens effectively reduce the noise generated by traffic by means of sound absorption, reflection and isolation. During the sound transmission process, the sound insulation screens will act as a shield, affecting the transmission of sound waves. At the same time, the sound-absorbing materials inside can absorb a lot of sound waves, further reducing the spread of noise.

[0003] At present, the installation methods of sound insulation panels mainly include using cranes and manual methods. Although installation by crane can achieve higher installation efficiency, this method is relatively cumbersome and has high cost. In contrast, manual installation faces certain safety risks. Workers need to stand on the protective walls on both sides of the bridge to work. However, such a working environment makes them lack adequate protection measures on both sides during the installation process, which increases the risk of falling from the bridge and makes the entire installation process quite dangerous.

[0004] Therefore, since the sound insulation panels of the above-mentioned bridges need to be installed manually, and the workers have no protective measures during installation, which makes them easily fall from the bridge, a bridge noise-proof installation structure can be designed. Through the electric telescopic and pneumatic telescopic structures combined with the gear transmission structure, the safety of the workers can be guaranteed while the sound insulation screen is installed.
