A group pile type bridge anti-ship collision device

Abstract

The application relates to a group pile type bridge anti-ship collision device, which belongs to the field of bridge anti-ship collision devices. It includes structural piles and floating islands. The structural piles are arranged around the outer periphery of the bridge. The floating island is composed of multiple sections of floating boxes connected by connectors. The floating boxes are installed on the structural piles. There is a gap between the floating island and the bridge. There is a sealed air chamber to make the floating box float in the water. There are rollers on the structural piles. The rollers protrude from the surface of the floating box. The surface of the rollers is coated with lubricating glue. . In the present application, by arranging floating islands, structural piles and rollers, and by applying lubricating glue on the rollers, when the ship hits the floating island, it can be guided to slide toward the side wall of the floating island by contacting the rollers, so that the ship is not easy to stop instantaneously. If the impact force is too large, it also increases the impacted area of ​​the floating island, so as to better dissipate the energy of the ship and play a good anti-collision protection effect on the bridge.

Description

technical field [0001] The invention relates to the field of bridge anti-ship collision devices, in particular to a group pile type bridge anti-ship collision device. Background technique [0002] With the rapid development of my country's transportation industry, the number of bridges has increased year by year. After the bridge is completed and put into use, the collision of ships passing through the bridge must be considered. [0003] Although the anti-collision capability of the bridge mainly depends on the structure of the bridge itself, in order to reduce the risk of affecting the overall structure of the bridge due to partial damage to the bridge, it is necessary to install necessary anti-collision devices. The existing anti-ship collision device is generally a steel structure fender or a flexible material pontoon, which can undergo plastic deformation to dissipate energy when it is hit by a ship, but the local deformation and energy dissipation of the anti-ship colli...

AI Technical Summary

Problems solved by technology

The existing anti-ship collision devices are generally steel structure fenders or flexible material buoys, which can undergo plastic deformation to dissipate energy when hit by a ship, but the local deformation energy dissipation of the anti-ship collision device is low, and this type of anti-ship collision Most of the devices are in direct contact with the bridge. Once the local deformation and energy dissipation of the anti-ship collision device cannot withstand the impact force of the ship, the impact force of the ship will still be transmitted to the bridge, which is not conducive to the protective effect of the bridge.
