Multi-stage buffering energy-consumption type anti-bumping corrosion-resistance steel floating box

Abstract

The invention relates to a multi-stage buffering energy-consumption type anti-bumping corrosion-resistance steel floating box. The steel floating box comprises a first-stage buffering retractable rolling contacting module, a second-stage energy-absorbing-sliding contacting module, a third-stage energy-consumption-corrosion-resistance steel box body, wherein the first-stage buffering retractable rolling contacting module comprises corrugated energy-absorbing bases which overlap in the bumping direction and a rolling assembly which can generate rolling friction on a bridge structure, the second-stage energy-absorbing-sliding contacting module comprises rubber fenders which overlap in the bumping direction and a sliding assembly which can be in sliding contact with the bridge structure, and the third-stage energy-consumption-corrosion-resistance steel box body comprises a bumping sinking-preventing sub module and an anti-bumping sub module. Compared with the prior art, multi-stage floating matter and ship bumping of the bridge structure can be achieved; multi-stage repairing of the device can be achieved on the premise that the bridge structure is effectively protected; the corrosionresistance maintenance problem of the anti-bumping device in rivers, lakes and seas can be solved by the excellent corrosion resistance of a composite steel plate, and the engineering and economic benefits are outstanding.

Description

technical field [0001] The invention relates to an anti-floating device for a bridge structure and a ship collision floating device, in particular to a multi-stage buffer energy-consuming anti-collision and corrosion-resistant steel buoy box. Background technique [0002] Engineering measures to reduce the risk of ship collisions on bridges. When the impact force of the ship is close to or much greater than the bearing capacity of the bridge pier, the anti-collision protection system attached to the bridge pier can protect the bridge pier from impact damage and avoid the resulting collapse of the bridge superstructure. In order to meet the requirements of bridge durability, even when the impact force of the ship is less than the carrying capacity of the pier, anti-ship facilities of corresponding scale can be installed to prevent damage to the durability of the pier such as the pier concrete being knocked down by the ship. [0003] Compared with fixed installations, floatin...
