The sound barrier screen is widely used in several fields. A common fixed sound barrier is installed as follows. First, a steel plate is welded to the bottom edge of both ends of the sound barrier on the construction site enclosure. There are mounting holes at the four corners of the steel plate, and then the diameter The 10mm and 40mm long steel bars are covered with wires, and the lower end is bent and anchored in the foundation formwork. The positions of the four steel bars are matched with the positions of the mounting holes on the steel plate, and the concrete is poured. After the formwork is removed after the curing period, the sound barrier is installed on the concrete. Finally, fasten the upper end of the steel bar with washers and nuts 3 of corresponding size to complete the installation of the sound barrier. However, conventional sound barrier screens need to be installed in place on the fence of the entire construction site in order to achieve the effect of comprehensive sound insulation and noise reduction, and a lot of manpower and material resources are invested. For example, if a single side of a construction site is 200m long and 20m wide, about 145 sound barriers need to be installed, and 145 pieces of steel plates, bent anchor bars, nuts, concrete formwork and other materials need to be installed. The characteristic of the mobile sound barrier is that it can be moved and fixed flexibly. If a single side of a construction site is 200m long and 20m wide, only the sound insulation sound barrier around the construction area of the project needs to be invested, and the construction structure section is 20m long. , basically only need to invest about 13 to 20 mobile sound barriers. Compared with conventional sound barriers, the amount of investment is 7 times that of mobile sound barriers. The mobile sound barrier can not only reduce the cost of investment, but also has advantages in recycling. The installation and disassembly of the mobile sound barrier is simple, and its base size and weight are small, which is convenient for transportation and storage. The traditional sound barriers are fixed on the construction access road, on the isolation pier and on the self-made concrete foundation. As for the "base" of the conventional sound barrier, it is basically immovable, or its own weight is particularly large, it is difficult to transport and store, and it is easy to be damaged, and the cost of secondary transportation and storage is relatively high. The manpower and material input of the mobile sound barrier is 1/7 of that of the conventional sound barrier (according to the above example). In terms of recycling, it can not only be moved, installed and disassembled flexibly, but also convenient for transportation and storage. Under normal circumstances, the loss of the mobile sound barrier is very small, and it can be recycled many times. Compared with conventional sound barriers, its cost is greatly reduced.

It should be noted that, for the convenience of description, the sound and sound mentioned in the utility model are synonyms. The above-mentioned embodiments can be freely combined as required. The above is only a preferred embodiment of the utility model, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the utility model, some improvements and modifications can also be made, these improvements and Retouching should also be regarded as the scope of protection of the present utility model.
