Since the introduction of rubber fenders into China in the mid-eighties, it has always been used for ports, docks and some ships. Since the collapse of the Jiujiang Bridge in Guangdong in June 2007, the collision of bridge piers has become a hot development. The project, some owners and large design institutes began to pay attention to the anti-collision project of the new super bridge, and some professional anti-collision equipment production enterprises such as Jiangsu Anjin Rubber Co., Ltd. appeared in the market. As the main product of anti-collision damping energy absorption, the rubber fender is selected for its single focus on the dock.

Bridge anti-collision and "three is not bad", the selection of rubber fenders is mainly based on navigation conditions, ship tonnage, water level and so on. Nowadays, more arched V-shaped rubber fenders are used. Although the fenders have been used in many ways, the piers have a lot of rows and turns, but because the fenders have less energy absorption, the surface is easily scratched and damaged and easy to fall off. , easy to age. When the time is long, the foundation does not have the protective effect. In addition, the threshold of the product is low, many small workshops have low cost and cut corners, and some products are even 3-5 young and lightly broken into powder. Invalid.
The rolling rubber fender resolves the force of the pier when it is hit by a large displacement. Used in some narrow navigation holes, it is also the right choice. However, because of the high cost of the product, many applications are unlikely.
In summary, the anti-collision effect can be achieved well, and the cost should be saved. The super arch type (SA type, the second generation of V type) combined rubber fender, 2-5 rubber fenders (or more) should be used. After sharing an anti-collision panel, the ultra-high molecular polyethylene board (ie, UHMW-PE) is anchored on the anti-collision panel, and the rubber fender anti-collision system can be arranged around the whole pier according to the pier. This way there is no dead point from any point of impact. When the vessel hits, the entire anti-collision plate is forced to absorb energy through the rubber fender behind it. This combined anti-collision system works well to withstand the impact of large ships. Low cost (many cut the number of rubber fenders used, long life.
