Description
Technical Field
The invention belongs to the technical field of bridge collision prevention, and particularly relates to a combined assembly type bridge ship collision prevention device.
Background
With the development of the water transportation industry, a bridge collision accident of a ship occurs, so that the bridge and the ship are damaged, huge economic loss and casualties are brought, and the installation of a protective device at the position of a pier is particularly important.
The method for preventing and reducing the occurrence of the ship bridge collision accident mainly comprises early warning collision prevention and passive collision prevention. The early warning and collision avoidance is to arrange early warning equipment near a bridge pier, monitor the motion information of a ship, predict a flight path line, find the risk of the ship colliding with the bridge in advance, remind the ship to adjust the course in time and avoid colliding with the bridge; the passive collision avoidance is that various collision avoidance devices are arranged near the bridge pier, and the collision avoidance devices absorb energy to reduce serious consequences caused by bridge collision accidents of a ship. At present, the passive anti-collision device mainly has the structural forms of cluster anti-collision piles, fence anti-collision pile groups, self-floating steel sleeve boxes, arch self-floating lifting anti-collision devices and the like. The device needs large transportation when being installed, is inconvenient to construct and install on site, is not easy to maintain and replace after being damaged, and has higher cost; part buffer stop direct mount is on the pier, and the impact force is concentrated on the installation fixed position more when being strikeed, and the anticollision effect is relatively poor.
