Reinforcement type float cylinder type composite anti-collision device

Abstract

The invention belongs to the anti-collision technical field. A reinforcement type float cylinder type composite anti-collision device is formed by connecting multiple float cylinder units. Each float cylinder unit comprises a hollow barrel-shaped surface layer and reinforcing ribs, wherein the surface layer comprises an outer layer, an inner layer and an elastomer filling layer arranged between the outer layer and the inner layer, and the reinforcing ribs are arranged in a hollow cavity of the surface layer. The reinforcement type float cylinder type composite anti-collision device has the beneficial effects that the structural form of a float cylinder is a hollow cylinder form, the structure is stable, and the cylinder structure is smaller in wave force compared with a rectangular structure and is suitable for bad wave environments with strong wave functions, uncertain wave directions and the like; and elastic-plastic deformation energy of an anti-collision structure is high so that energy absorption of an anti-collision block can be improved, and a bridge pier can be further protected. Meanwhile, installation is convenient, maintenance is simple, and the maintenance cost is low.

Description

Technical field [0001] The invention belongs to the technical field of collision avoidance, and in particular relates to an enhanced buoy type composite material collision avoidance facility. Background technique [0002] With the construction of more and more large highway bridges across the river and the improvement of the level of the river channel, more and more large-tonnage ships have entered the river, and the channel evolution after the bridge is built, these bridges across the river are at risk of being hit by ships Significantly increased. The function of the anti-collision device is to reduce the damage to the bridge by changing the collision direction of the ship or reducing the impact force of the ship, while reducing the damage to the ship and the anti-collision device as much as possible. [0003] According to the classification of passive anti-collision facilities by the International Bridge and Structural Engineering Association: 1) Protective plate system; 2) Sup...
