Attached type ship-collision-prevention structure of steel-concrete combined structure

Abstract

The invention discloses an attached type ship-collision-prevention structure of a steel-concrete combined structure. The structure is attached to the outer wall, located on the water surface elevation, of a bridge pier or bearing platform, and comprises one or multiple units, and each unit comprises a shell of a box-shaped structure. Each shell is made of a strain strengthening UHPC concrete material, a framework is mounted in a hollow inner cavity of each shell, each inner cavity is filled with foam concrete, each framework comprises multiple thin steel tubes and multiple structural steel lattices, the thin steel pipes are parallel to each other, the length direction of each thin steel pipe is parallel to the horizontal direction, every two adjacent thin steel pipes are connected throughthe corresponding structural steel lattices, and a net-shaped structure is formed. Multiple cavities defined by the structural steel lattices and the inner walls of the shells are filled with the foamconcrete. Due to application of the structure, the outer surface of a bridge pier ship-collision-prevention facility is free of steel structure exposing, the internally-filled foam concrete can better improve the energy dissipation after ship collision, the bridge ship-collision-prevention property can be improved, durability is improved, and meanwhile, self floating of the bridge pier ship-collision-prevention facility is achieved.

Description

technical field [0001] The invention relates to the technical field of bridge pier protection, in particular to an anti-ship collision structure of an attached steel-concrete composite structure. Background technique [0002] Pier anti-ship collision facility is a kind of existing technology that is widely used in various bridge pier protection. Among them, the attached pier anti-ship facilities mainly fall into two categories: steel and FRP materials. [0003] In practical application, there are certain defects in the above two types of anti-ship collision facilities for bridge piers. [0004] The steel attached pier anti-ship collision facilities, in practical application, the corrosion of metal materials is difficult to deal with, and the maintenance workload after the anti-corrosion paint is scratched is also relatively large, and the maintenance cost is relatively high. [0005] The attached pier anti-ship collision facility of FRP material solves the corrosion proble...

Problems solved by technology

[0004] The attached steel pier anti-ship collision facilities, in practical application, the corrosion of metal materials is difficult to deal with, and the maintenance workload after the anti-corrosion paint is scratched is also relatively large, and the maintenance cost is high

[0005] The attached pier anti-ship collision facility of FRP material solves the corrosion problem, but the structure is relatively thin, the anti-collision performance is limited, and the connection with the cap under the action of wave dynamics is also very high. In water bodies with large waves prone to problems
