The world's first bridge wearing a rubber fender "anti-collision"
- 2019-04-23-

The rubber fender is a tight and safe protection method for ships in port ships. It is used for the purpose of receiving energy and buffering impact force when a collision occurs between ships or between ships. In the early days, the fenders were replaced by scrap tires. Following the reversal of the ship transport industry, the request for fenders was also popularized. Professional fenders were created and the technical scale of response was set. [1] . The mechanical performance of the fender includes the 50% tightening rate of the defensive force to receive energy, and the small fender (height <500mm, 50%="" tightening="" deformation=""><250mm). stop="" on="" the="" electronic="" material="" testing="" machine;="" deal="" with="" the="" large-scale="" fender="" (height="">100 mm ~ 2,500 mm), the test requirements of the performance index will be more than 100 mm above the deformation of the fender, and the load-deformation curve of the demand record response . Ordinary inductive or differential transformer displacement sensors can not meet the requirements, grating, square grating, magnetic grid or capacitive grid displacement sensor is expensive, for this reason, this paper proposes a lightweight method of measuring displacement - ——Linear-angle-resistance-voltage measurement method, using this principle to test the cheap sensor installation with unacceptable measurement accuracy. Based on this, a set of microcomputers for testing the mechanical properties of rubber fenders was developed. Test system and used for product quality testing of related companies.

The safety of the sea patrol boat is high, and the Jiangsu Runyang Bridge is “off” and “anti-collision back protective clothing”. On the two water bridge piers of the North Bridge of Runyang Bridge, a large anti-collision retainer with a diameter of 3 meters was placed. In addition to the previous construction and resettlement, the four water piers of the current Runyang Bridge have all been equipped with protective rings.

The cross-river bridge has always been a key tool for the safety supervision of maritime traffic. Runyang Nianqiao North Bridge is located in the Yizheng Jieshui River of the Yangtze River. The daily average ship traffic flow in the navigable waters is more than five or six hundred times.

At present, the bridge has been completed, and the four piers that stand in the middle of the river have always been in the form of no anti-collision measures. From 2009 to 2010, the Ministry of Communications developed a special management action of “two defenses” (anti-collision and anti-leakage). Runyang Beibei Bridge was listed as a “hidden hidden danger tool” by Yangzhou Maritime.

In Yangzhou Maritime's repeated urging high, Runyang Nianqiao Retreat Co., Ltd. stopped the investigation and demonstration of the bridge anti-collision method, and repeatedly invested in the action, and finally put it into action at the end of 2012, for the four bridge piers to cross the water On the protection ring against the collision of 5,000-ton ships.
