Description
Technical Field
The invention belongs to the technical field of water building safety protection, and particularly relates to an ocean pier system for protecting a ship body by adopting a yaw mechanism.
Background
With the continuous development of the transportation industry, a large number of bridges across the sea and the river are continuously built. The bridge is a busy navigation channel in most of rivers and sea areas, the conditions of water flow, billows, storms and the like are complex, and the bridge inevitably bears certain risk of ship collision. Relevant researches have been carried out at home and abroad, the ship bridge collision theory is put forward, and bridge protection facilities are designed. The basic purpose of bridge collision avoidance is to prevent the bridge from being structurally damaged due to the fact that the ship impact force exceeds the design bearing capacity of the bridge pier, and to protect the ship as much as possible and minimize the loss. The crash facilities are different in type and work mechanism. When a ship collides or rubs a bridge pier or an anti-collision pier of a bridge, the momentum of the ship with a certain speed is very large, and in order to reduce the damage of the ship to the bridge pier caused by the collision, an anti-collision box, a double-wall anti-collision steel sleeve box or a flexible energy-consumption anti-collision device is usually arranged on the bridge pier to achieve the aim of protecting the bridge pier. The anti-collision box or the double-wall anti-collision steel sleeve box is used for blocking the ship, consuming the kinetic energy of the ship, decelerating the ship, delaying collision and weakening the collision force of the ship to a pier; when a ship collides or collides a pier, the kinetic energy of the ship is huge, and the anti-collision box, the double-wall anti-collision steel sleeve box and the flexible energy-consuming anti-collision device can only prevent small ships due to the very limited elastic buffering capacity of materials, can not well absorb the huge kinetic energy of the ship for the ships with larger mass or higher navigational speed, have poor energy dissipation and anti-collision effects, are easy to crash, have potential safety hazards, have short service life, and need to be replaced immediately after being crashed, and the anti-collision box is formed by welding steel plates, is a huge object, weighs thousands of tons, is not easy to install, is easy to corrode after being crashed, and affects the service life. Therefore, the existing protection device for the pier is to be further improved, the anti-collision pier at the present stage is a very common marine traffic safety facility and is widely applied in some dangerous areas, when objects such as a ship body and the like collide with the pier, the anti-collision pier or the anti-collision mounting suite with the buffering performance can greatly buffer the huge impact force generated by the collision, so that the serious consequences generated by traffic collision accidents can be greatly reduced, the firm anti-collision pier with strong anti-collision capability and good buffering performance is a very necessary marine traffic safety infrastructure under the action of the huge impact force, nearly hundreds of river-crossing and sea-crossing bridges are built in China in the last twenty years, but many of the bridges are super engineering, but the accidents such as serious casualties, property loss and the like caused by the collision of the objects such as the ship body and the like with the pier, the method has the advantages that the method is not enough in bridge pier anti-collision design and anti-collision measures of marine traffic, the initial research on bridge pier anti-collision in China is late, the early attention degree is not good enough, and many anti-collision design theories and calculation methods refer to foreign research results, so that the key point is to develop and design effective anti-collision bridge pier facilities, the design aims of not damaging bridges, not damaging ship bodies and not firming bridge piers are achieved, and the method plays an important role in influencing the development of marine traffic in national economy and society.
