The anti-collision technology of the pier of the Hong Kong-Zhuhai-Macao Cross-sea Bridge has become the top priority of the bridge design. JSHY Technology Engineering Co., Ltd. uses fixed composite material flexible energy dissipation fender according to the pier type of Hong Kong-Zhuhai-Macao Bridge. The fender is composed of a composite material facing surface, reinforced connecting plate, energy dissipation column, closed-cell energy-dissipating core material, and energy-dissipating closed-cell foam materials, etc. are introduced through vacuum and integrated into a shape of "7", which becomes The "protective clothing" of the Zhu'ao Bridge effectively reduces the destructive force caused by the collision of the ship with the bridge and improves the safety of shipping.
