Example Embodiment

[0019] Figure 1 to Figure 3 An embodiment of the energy-absorbing guided pier anti-collision device of the present invention is shown. The pier anti-collision device includes a pipe pile group 1 arranged next to the pier 4, and the pipe pile group 1 is provided with an anti-collision pontoon 2 in the collision When it happens, the bow or hull of the ship first comes into contact with the anti-collision pontoon 2. The anti-collision pontoon 2 is squeezed and deformed under the impact of the collision force while absorbing energy; the collision avoidance pontoon 2 deforms and collides with the contact part of the ship The energy continues to be transferred to the pipe pile group 1, causing flexural deformation of the overall structure of the pipe pile group 1, so that the pipe pile group 1 absorbs part of the energy. The overall elastic deformation of the pipe pile group 1 has a certain reaction force on the ship, and the reaction force affects the ship. The navigation has a cer...

Abstract

The invention discloses an energy-absorbing guide anti-collision device for a pier. The anti-collision device comprises a tubular pile group arranged beside the pier, wherein, an anti-collision buoyancy tank is sheathed outside the tubular pile group. The energy-absorbing guide anti-collision device for the pier has the advantages of simple structure, low cost and capability of absorbing energy during the collision process and guiding ship motion.

Description

technical field [0001] The invention relates to a bridge protection device, in particular to an energy-absorbing and guiding pier anti-collision device. Background technique [0002] The piers of the bridges spanning the channel may be collided with ships. In order to resist the impact force of the ship, the design of the pier must consider the impact force of the ship. In our country, accidents of boats crashing into bridges occur frequently. For example, the Wuhan Yangtze River Bridge had 70 accidents from its completion in 1975 to December 18, 1999. Among them, more than 10 major accidents had direct economic losses of millions of dollars. There have been more than 300 incidents of boat collisions with bridges on the three main water systems of the Yangtze River, the Pearl River, and the Heilongjiang River. Although not every collision accident leads to a major tragedy of bridge destruction, it is certain that the service life, safety and earthquake resistance of the br...
