The Hong Kong-Zhuhai-Macao Bridge uses a rubber isolation bearing with a length and width of 1.77m, which is currently the world's largest rubber isolation bearing, developed and provided by ZZSD New Material Technology Co., Ltd. This product can effectively resist the impact of typhoon, earthquake, tsunami and other disasters or man-made accidents on the bridge.
According to reports, rubber isolation bearings are widely used in houses, highways, bridges and other buildings. The most critical technology is the rubber technology located in the middle of the bridge support, known as the "heart" of the bridge support. The greater the damping of the rubber, the stronger the ability to consume energy, generally reducing the seismic intensity by 0.5 to 2 degrees. High-damping rubber isolation bearings can absorb and consume more than 40% of the vibration energy in the test.
In view of the special working conditions of the Hong Kong-Zhuhai-Macao Bridge with a large span and complex terrain, ZZSD has adopted a unique rubber formulation process and detection technology to develop the world's largest high-damping rubber isolation support with a length of 1.77m and a width of 1.77m. The bearing capacity of this bearing is about 3 000t, which can provide buffer protection for the Hong Kong-Zhuhai-Macao Bridge against the typhoon of magnitude 16, earthquake of magnitude 8, and the impact of 300,000 tons of giant ships.
