Description
Technical Field
The invention relates to the technical field of bridge collision avoidance, in particular to a novel self-resetting pier collision avoidance device.
Background
With the economic construction and development of China, traffic infrastructure is also rapidly developed, a single-seat bridge is continuously pulled out, the bridge bears the important role of economic development of two places, the civil problem is also concerned, and more large-scale bridge projects are established. Among which hundreds of millions and billions of bridge projects.
While the land transportation is developed, the development of the water transportation is not small and various, the sizes and the tonnage of ships are larger and larger, the channels on the water are crowded, and the like, the water transportation is also continuously developed, the advantages and the disadvantages of the water transportation are discussed continuously, and the problem of the water transportation also needs to be studied seriously. Accidents caused by ship collision with bridge piers are frequent in recent years, and natural factors and artificial accidents are caused; however, such accidents often cause huge economic loss, ships can be damaged greatly in the collision process, bridges can also bear huge damage in the collision process, piers can crack due to huge impact force to cause unsafe factors, and if the tonnage of the ships is too large, the bridges can be directly collapsed due to collision, so that the ships can be covered. Thus, huge economic loss is formed, and the well-known value of the bridge is shown not only in the aspect of high manufacturing cost but also in the social value born by the bridge. Therefore, the research and development of pier collision avoidance are particularly important. It is uneconomical and unrealistic to increase the impact load of the designed bridge pier from the surface alone, so it is very important to develop an economical and realistic anti-collision device for the bridge pier. At present, simple springs and rubber are paved on bridge piers of most rivers to buffer the impact of ships, and a plurality of technologies such as a pontoon are utilized to protect the bridge piers. The springs and the rubber are easy to install, but have small buffering capacity, and the impact of the ship can still be transmitted to further act on the bridge pier. The float boat technology has the problems of easy damage and complex replacement. Therefore, a pier anti-collision device is needed, which can effectively absorb the impact energy of ships to achieve the buffering effect, can also turn the ship, and can still retain most of the energy on the ship, thereby reducing the damage of the bridge and the ship in the impact process and having the advantage of simple installation.
