Description

Technical Field

[0002] The subway roof is centered on the subway, and subway supporting facilities are built in its upper space, and multi-level development and construction such as commercial, office, and residential areas are carried out. Rail transit is used as a guide to promote urban development, and supporting services are provided for the city around the subway. In large cities, it usually refers to commercial and residential buildings built at the ground entrances and exits of the subway. The operation of the subway will produce a lot of noise, which can easily affect the people around the subway. Therefore, the subway roof needs to be treated with vibration reduction and noise reduction; the existing subway roof vibration reduction and noise reduction structure has certain disadvantages when used. When the subway roof is treated with vibration reduction and noise reduction, vibration reduction is mostly carried out through vibration reduction plates. The vibration reduction material is single and the vibration reduction effect is poor. In order to ensure the effect of vibration reduction and noise reduction, it needs to be frequently inspected and repaired, and disassembly and replacement are very inconvenient. For this reason, we propose an efficient vibration reduction and noise reduction structure for the subway roof. Utility Model Content
