A ground barrier vibration damping device

Abstract

The invention discloses a ground barrier vibration damping device, which relates to the technical field of vibration isolation buildings; it comprises a vibration damping plate, a particle layer, a water bag layer, a friction layer and a high damping plate; a layer of powdery solid particles is laid inside the vibration damping plate A granular layer is formed, and the water bag layer is arranged between the damping plate and the friction layer. The water bag layer includes several closely arranged water bags. The layers are able to rub against each other, and the device can effectively reduce the vibration of the adjacent foundation.

Description

technical field [0001] The invention relates to the field of vibration-isolation building technology, in particular to a ground barrier vibration-damping device. Background technique [0002] With the rapid development of the transportation industry, the environmental vibration caused by the traffic load has attracted more and more attention. Vehicle vibration has many adverse effects on the structure of houses along the road, residents' life and work, especially in the urban roads with heavy traffic. The impact of environmental vibration caused by vehicles on some urban roads has far exceeded the relevant national regulations. It will interfere with people's living and working environment, affect people's physical and mental health, and cause damage to buildings, underground pipelines and some high-precision instruments and equipment near the vibration source, resulting in large economic losses. [0003] Therefore, it is very important to study vibration isolation measures...

Problems solved by technology

Vehicle vibration has many adverse effects on the structure of houses along the road, residents' life and work, especially in the urban roads with heavy traffic. The impact of environmental vibration caused by vehicles on some urban roads has far exceeded the relevant national regulations. It will interfere with people's living and working environment, affect people's physical and mental health, and will cause damage to buildings, underground pipelines and some high-precision instruments and equipment near the vibration source, resulting in large economic losses.

[0003] Therefore, it is very important to study vibration isolation measures. At present, urban vibration isolation is mainly to install a vibration isolation barrier made of a single material in the foundation. Although it has a certain vibration reduction effect, its vibration reduction effect is still not satisfactory. Requirements for the vibration isolation effect that the vibration isolation barrier can achieve
