Bridge anti-ship-collision structure

Abstract

The invention discloses a bridge anti-ship-collision structure which comprises a plurality of layers of anti-collision sleeve boxes arranged outside a bridge bearing platform in a surrounding mode, wherein the top faces of the anti-collision sleeve boxes adjacent to the bridge bearing platform are connected to the upper surface of the bridge bearing platform in a suspended mode, and the side wallsof the anti-collision sleeve boxes are connected with the side walls of the bridge bearing platform in an attached mode; and the top surfaces of the adjacent layers of anti-collision sleeve boxes areconnected in a suspended manner, and the side walls are connected in an attached manner. Through the anti-collision design of multiple layers of anti-collision sleeve boxes, the anti-collision sleeveboxes of the corresponding layers can be selected according to the anti-collision grade; when collision occurs, the outer-layer anti-collision sleeve box deforms firstly, the collision force is released, and the ship is stopped; and when the deformation of the outer-layer anti-collision sleeve box is not enough to release all the collision force, the inner-layer anti-collision sleeve box deformsalong with the outer-layer anti-collision sleeve box, and the remaining collision force is released. The collision energy of a collision ship is absorbed through deformation of the inner-layer anti-collision sleeve box and the outer-layer anti-collision sleeve box, so that the purpose of protecting a bridge structure from being damaged by collision is achieved.

Description

technical field [0001] The invention belongs to bridge anti-ship collision technology, in particular to a bridge anti-ship collision structure. Background technique [0002] With the rapid development of the national economy and the implementation of national strategies such as the integration of the Yangtze River Delta and the Guangdong-Hong Kong-Macao Greater Bay Area, the implementation of a series of super-large cross-sea bridges will inevitably be accelerated. Usually, large-scale sea-crossing bridges are located in economically developed areas with busy maritime trade, and they will inevitably face the problem of crossing dense waterways and defusing the risk of ship collision. Taking effective measures to prevent passing ships from colliding with bridges is a very important link in bridge construction. At present, there are more than 10 kinds of anti-collision structures for bridges, ranging from attached anti-collision structures to floating net protection systems, ...

AI Technical Summary

Problems solved by technology

For ships over 50,000 tons, due to the huge impact force, if designed according to conventional ideas, the scale of the anti-collision facilities will be huge, and there will be problems such as difficult construction and installation, poor economy, and extremely difficult to dismantle and replace after impact damage
