[0002] With the rapid development of urbanization and infrastructure construction, the development and utilization of underground space has become an effective way to ease the pressure of ground traffic and increase public facilities. The construction of subway tunnels, integrated pipe corridors, underground parking lots and other projects is becoming more and more frequent. These underground projects generate a lot of noise during the excavation, drilling, blasting and other operations, which not only affects the daily life and health of surrounding residents, but also may have adverse effects on the environment. Therefore, effectively controlling and reducing underground construction noise has become one of the problems that need to be solved in current urban construction.

Secondly, these barriers are often of fixed height and length and cannot be adjusted according to the construction depth and the different noise sensitivities of the surrounding environment. In addition, traditional materials such as masonry and concrete are heavy and cumbersome to install, which not only increases construction costs but may also prolong the construction period. Furthermore, their environmental protection and recyclability are poor, and they are prone to waste resources and environmental pollution after being abandoned. Summary of the invention
