Integrally curved surface-shaped pier anti-collision floating type casing box

Abstract

The invention discloses an integrally curved surface-shaped pier anti-collision floating type casing box. The pier anti-collision floating type casing box is obtained by splicing and enclosing a plurality of independently sealed box bodies with elliptic sections through joints; the box bodies are made of sandwich plates; and the sandwich plates are obtained by using polyurethane as sandwich layers and steel plates as panels. The pier anti-collision floating type casing box is integrally curved surface-shaped and sleeved on a pier like a rubber kayak or a life buoy; the sections of the box bodies can be also designed in elliptic or circular shapes according to the size of a ship; the casing box totally has better elastic performance; a ship bow is easy to shift to change the direction when impact kinetic energy is absorbed; and a horizontal collision force is decomposed, so that energy is exchanged among the ship, the anti-collision casing box and the pier and a protective effect on each party is achieved. As the box bodies are manufactured by using the sandwich plates with stronger anti-impact capacities, stiffening structures can be not arranged or less stiffening structures can be arranged; therefore, defects that a large amount of stiffening plates and brackets must be arranged in a common buoyancy tank and the exterior of the common buoyancy tank only can be formed by combining a plurality of planes in order to guarantee necessary strength and rigidity are overcome.

Description

technical field [0001] The invention relates to a pier anti-collision device for an inland waterway, in particular to a pier anti-collision floating casing with an overall curved surface. Background technique [0002] In navigable rivers, the accidents of ships colliding with bridge piers have existed for a long time and generally, which have caused great harm to the safe operation of bridges and navigation. Although there are fewer accidents of collapse after the ship hits the bridge, the consequences of the ship hitting the bridge are still shocking. For bridges built on inland waterways with small tonnage ships, due to large changes in water level and flow velocity, a pier anti-collision structure that is not too large in size, does not occupy the waterway, has high buoyancy, is easy to push the bow, and has good impact resistance is required. Cover box, existing various anti-collision facilities are all unsatisfactory to above-mentioned requirement. Contents of the in...

[0002] In navigable rivers, accidents of ships colliding with bridge piers have existed for a long time and generally, which have caused great harm to the safe operation of bridges and navigation

Although there are fewer collapse accidents after the ship hits the bridge, the consequences of the ship hit the bridge are still shocking.

For bridges built on inland waterways with small tonnage ships, due to the large changes in water level and flow velocity, a bridge pier that is not too large in size, does not occupy the waterway, has high buoyancy, is easy to push the bow, and has good impact resistance. Cover box, the existing various anti-collision facilities are not ideal for the above requirements
