[0002] Railway construction construction noise reduction sound insulation board, it usually realizes the noise reduction effect through the reflection, absorption and barrier noise transmission path. This sound insulation board not only can significantly reduce the noise level, but also can provide a relatively quiet working and living environment for construction workers and surrounding residents.

[0003] The terrain along the railway is complex and changeable, and the existing device cannot quickly adjust the height, resulting in reduced adaptability of the device, making the device difficult to install and the noise reduction effect poor, and multiple sound insulation boards are fixed by bolts, making disassembly more troublesome and having limitations.

[0004] The reason for this problem is that the terrain along the railway is complex and changeable. The existing noise reduction sound insulation board device often lacks the function of quickly adjusting the height in design, which directly leads to a significant reduction in the adaptability of the device when facing different terrains. Because the height cannot be quickly adjusted according to the actual situation on site, the installation personnel often need to do a lot of measurement and planning work before installation, but there will still be difficulties in installation, which will affect the noise reduction effect. When the sound barrier needs to be moved, replaced or maintained, workers need to spend more time and effort to disassemble and reassemble the bolts, which not only increases the maintenance cost, but also limits the flexibility and reusability of the sound barrier. In particular, in the environment along the railway, which needs frequent maintenance and upgrading, the limitations of bolt fixation are more obvious, so we propose a railway construction construction noise reduction sound insulation board to solve the above problems.
