Typhoons, earthquakes, tsunamis ...... lingering cross-sea bridge, "ghost", how to prevent and reduce their super-destructive Bridge? Recently, Zhuzhou Times New Material Technology Co., Ltd. developed the world's largest rubber bearings come out, and will be applied in the largest cross-sea bridge - the Hong Kong-Zhuhai-Macao Bridge. It appears, will effectively resist the impact of the disaster or man-made incidents of cross-sea bridge.
Isolation movable seismic isolation device is installed between the foundation and the foundation of the building, when the external force such as earthquake struck, the device just like to play ball, the vibration energy conversion and consumption, "avoid" building affected by vibration. Rubber bearings of this type of isolation equipment, it is widely used in housing, roads, bridges and other buildings.
The isolation bearing the most critical technology is located in the middle of the bridge bearing rubber technology, known as bridge bearing the "heart" of the rubber damping (free vibration attenuation friction and hinder) the greater the consumption energy capacity of the stronger, and generally reduce the seismic intensity of 0.5-2 degrees. Especially high damping rubber bearings, the test can absorb and consume more than 40% of the vibration energy.
