Description

Technical Field

[0001] This utility model relates to the field of municipal construction engineering technology, specifically a noise reduction device for municipal construction engineering. Background Technology

[0002] Municipal engineering refers to the construction or repair of urban buildings, roads, or squares. When roads are being built, the construction site is often open-air and located near residential or public buildings. The noise generated by the construction machinery can cause noise pollution to the surrounding environment. Therefore, it is necessary to use soundproof barriers and other equipment to enclose the construction site to isolate and reduce noise and prevent it from affecting the residents living nearby.

[0003] Existing soundproof barriers only use a single layer of soundproof panels for sound insulation, resulting in poor sound insulation. In addition, the existing soundproof barriers are connected by bolts, making them inconvenient to assemble and disassemble.

[0004] Based on this, a noise reduction device for municipal construction projects is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content
