Description

Floating pier anti-collision facility capable of unloading force and installation method thereof

Technical Field

The invention relates to the technical field of bridges, in particular to a floating bridge pier anti-collision facility and an installation method thereof.

In recent years, a large number of bridges are built in China, ships are developed in large scale and rapidly, the frequency of collision accidents between the ships and the bridges is gradually increased, and the collision consequences of the ships and the bridges are more and more serious.

Crash facilities generally meet the following requirements: (1) the ability to absorb energy is great, preferably the bow can be spread out so that most of the energy remains on the vessel; (2) the anti-collision device is reliable and safe; (3) the anti-collision facilities are more economical to manufacture, install, maintain and repair; (4) the anti-collision facilities cannot occupy too large area, cannot influence the navigation of the channel and occupy the channel as less as possible; (5) the structural form of the anti-collision facility is reasonably arranged as much as possible, and the damage of a collision ship is reduced to the maximum extent; (6) the new problem caused by the arrangement of the anti-collision facility is avoided; (7) the product is suitable for dry and flood; and water level change requirements such as rising tide and falling tide. The principle of setting up the anticollision facilities is as follows: (1) when a bridge collides, the bridge is generally damaged most seriously, so that the bridge can be used even if crashworthy facilities and ships are damaged; (2) in the event of a bridge collision, damage to the collision avoidance facilities is possible to some extent, but is preferably easy to repair; (3) when a bridge is collided, half of the responsibility is on the ship side, but the sinking of the ship causes huge economic loss, so when an anti-collision facility is designed, the damage condition of the ship is also considered, and the sinking accident is avoided.

Most pier anticollision facilities used at present all are installation spring or rubber on the pier, utilize spring or rubber buffering when the bridge bumps, reduce the loss that the accident caused, the effect that this kind of device that cushions when the striking can play is very limited, still can cause great impact damage to the bridge in many times, especially under the principle that the protection pier is preferred, more likely can cause devastating harm to the ship, threaten the safety of ship personnel, when the ship sails at night, the speed is very fast, when the load is great, the loss that the bridge bumps the accident and causes is still great.
