Description

Technical Field

[0001] The invention relates to the technical field of noise reduction barrier installation, and in particular to a road barrier for highway engineering construction. Background Art

[0002] Various construction operations are required during highway construction, such as digging foundation pits, tamping earth, driving foundation piles, on-site welding, etc. These construction operations will generate high decibel noise, and it is necessary to install and lay noise reduction barriers outside the road construction to prevent the noise from radiating outward and affecting the rest of surrounding residents.

[0003] A sound barrier is an acoustic barrier standing between the noise source and the sound receiving point. It is mainly used for sound insulation and noise reduction on highways, expressways, elevated composite roads and other noise sources. It is mainly composed of a steel structure support frame and sound insulation panels. The lower end of the steel structure support frame is fixed on the concrete track, and the sound insulation panel is inserted downward between two adjacent steel structure support frames.

[0004] The current noise reduction barrier has the following problems: during transportation, the transport personnel need to first move the sound insulation panels from the transport vehicle to the ground. When constructing, the workers carry the sound insulation panels and climb onto the scaffolding or elevator until they reach the height of the upper end of the steel structure support frame. Then, they hold the sound insulation panels and insert them one by one into the steel structure support frame. This increases the labor intensity of the workers. The workers stand on the scaffolding and need to lean out to insert the sound insulation panels downward, which may cause the risk of falling and is very inconvenient to install. Therefore, the existing noise reduction barrier has the defect of inconvenient installation method and low safety factor for workers during installation.
