Description

Device for preventing ship from impacting pier

Technical Field

The utility model belongs to bridge engineering protection field, in particular to pier position protection specifically is a prevent device of ship striking pier.

Background

In recent years, in order to adapt to the increasing of traffic volume, the construction quantity of cross-river sea bridges in all regions of the country is rapidly increased, meanwhile, the domestic waterway transportation has the characteristics of large transportation quantity and low cost, the quantity and ton level of navigation ships are increased year by year, the navigation mileage of inland waterway reaches 12.7 kilometers, 14.49 water transportation ships are owned, and more attention is paid to the safety of the waterway operation.

According to statistics, the ship bridge collision accidents recorded in China are increasing day by day, serious influences are brought to the operation of ships and upper broken bridges, the ship bridge collision accidents cause huge and irreparable losses to the traffic, economy and property in China, and the degree of accident injury caused by the fact that the ships collide the bridges is extremely urgent by adopting corresponding protection measures. The pier is the most important bearing structure of bridge, also is the position that boats and ships are relatively easy to collide, and the reasonable setting in this position prevents that the ship from hitting the facility and can reduce the injury of boats and ships striking pier to bridge structures, personnel and boats and ships to a very big extent.

At present, the common anti-collision treatment modes of bridge pier positions across bridges on navigation channels of China can be divided into three types, namely non-collision facilities, indirect collision facilities and direct collision facilities. For no anti-collision facility, the bridge structure is required to resist ship collision, once a collision accident occurs, no protective facility can block the collision ship, and the bridge body is easy to be threatened, so that potential safety hazard exists; the indirect anti-collision facility is an anti-collision safety barrier (such as an anti-collision pile group, a floating barrier net and the like) arranged outside a pier, but the protection performance is uncertain mostly without safety verification; the direct anti-collision facility mainly protects the bridge pier through a device arranged outside the bridge pier, the device and the bridge pier bear the impact of ships together, the horizontal resistance of the bridge pier and the buffering energy absorption of the device are utilized to reduce the ship impact, but along with the increase of water transport ships, the ship carrying capacity and the carrying speed, the self anti-collision design of a plurality of built bridges at present can not meet the safety requirement under the navigation environment.

In recent years, researchers have developed many research works aiming at ship bridge collision protection, and have achieved some achievements, but still have certain limitations: the pier anti-collision device made of the rubber material is only suitable for protecting the condition of light collision; the steel box-shaped anti-collision facility absorbs collision energy by utilizing plastic deformation of a structure, is suitable for the situation of strong collision, but cannot effectively reduce the damage of a ship body by self large damage when collision occurs. Therefore, materials applied to pier collision avoidance facilities need innovative exploration.

With the development of new materials, various new materials are produced, wherein high-performance porous aluminum is a novel material, the high-performance porous aluminum has superior characteristics in both structure and function compared with the traditional structural material, rigid anti-collision is changed into flexible anti-collision, and research shows that the foamed aluminum has the performances of light weight, energy absorption, shock absorption, electromagnetic shielding and the like besides the mechanical performances of high specific stiffness and superior specific strength, can work at high temperature, has high waterproofness, and has remarkable advantages as a pier anti-collision device material.

In conclusion, according to the anti-collision requirement of the upper span bridge pier and the requirement of the ship buffering performance, the device for preventing the ship from colliding the pier is provided by combining the characteristics of the porous aluminum material, and has the characteristics of simple construction and repeated reutilization.
