COLLISION BY A SHIP Technical Field The present disclosure relates to the technical field of bridge security, and in particular to a self-floating protection device for avoiding bridge collision by a ship.
Background As important engineering structures across rivers and also hubs for communicating land transportation between banks of rivers, bridges are playing a self-evident role in land transportation. However, bridges are man-made obstacles for water transportation ships. As a result, bridges and ships turn out to be opposite contradictions. In a sense, ever since the construction of bridges on navigable rivers, there has been the possibility of bridge-ship collisions and this possibility objectively exists throughout the whole life of bridges.
Water transportation 1s an inevitable component of comprehensive transportation system, and has been greatly developed in China in recent years. Navigation ships tend to be larger, faster and denser, while the bridge structures in navigable waters are more and more complex. Therefore, under the background of increasingly high navigation density, the ship-bridge contradiction is bound to be more prominent, and the possibility of bad bridge collisions by ships will also be larger. Apparently, it is necessary to provide collision-prevention devices for bridges with high navigation density and high navigation requirements, and to optimize and research performances of anti-collision devices.
The afore-mentioned information disclosed in the part of Background is merely for better understanding of the background of the present disclosure, and thus may include information that does not constitute prior art known to ordinary technicians in this field.
