Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention provides a multistage layered anti-collision device, and figure 1 shows a schematic sectional structure diagram of the multistage layered anti-collision device, the anti-collision device is provided with a middle cavity 10 for accommodating protected objects such as piers and the like, and when the anti-collision device is applied to the protection of bridges in a river channel, when ships with different tonnages impact the bridges, the impact force of the ships on the piers is absorbed, and the piers and the ships are protected. The multistage layering buffer stop includes: shell 9, foam module 7, concrete module 5, steel truss 1. A first accommodating cavity is formed in the shell 9 and is used for accommodating the steel truss 1, the concrete module 5 and the foam module 7; the foam modules 7 are arranged along the inner wall of the rubber layer 9, and a second accommodating cavity is formed in the foam modules 7; the concrete modules 5 are arranged along the inner wall of the second accommodating cavity, and a third accommodating cavity is formed in the concrete modules 5; the steel truss 1 is placed in the third accommodating cavity and clings to the inner wall of the concrete module 5; the first accommodating cavity, the second accommodating cavity and the third accommodating cavity are of hollow and closed annular structures.

Referring to fig. 3, the concrete module 5 is formed by mixing high-performance concrete and light balls 51 to form a honeycomb shape, so that the deformation energy dissipation capability of the anti-collision device is improved; since the light ball 51 is a light material ball having a density lower than that of the high performance concrete, such as a plastic ball, a foam ball, etc., the specific gravity of the concrete module 5 is reduced and the concrete module is easily floated on the water. The larger the number of the light balls 51 in the concrete module 5, the smaller the specific gravity of the concrete module 5, and the easier the anti-collision device floats on the water surface. A plurality of concrete modules 5 are wrapped by a first composite material 6 with fiber materials and then installed on the outer side of the stiffening steel truss 1.
The foam module 7 is internally provided with foam particles, and externally coated with a second composite material 8, such as glass fiber cloth, resin and the like.
In this embodiment, the outer shell 9 is a first buffer layer, the foam module 7 is a second buffer layer, the concrete module 5 forms a third buffer layer, and the steel truss 1 forms a fourth buffer layer. When a small-tonnage ship body impacts a pier, the rubber layer 9, the foam module 7 and the concrete module 5 can realize damping and buffering impact, and meanwhile, the ship and the pier are protected; when a large-tonnage ship impacts a pier, the steel truss 1 absorbs energy by utilizing the stable mechanical property of the steel truss, weakens the impact force on the pier and protects the bridge. The multistage layered anti-collision device provided by the invention can improve the tolerance of a bridge to the impact force of ship bodies with different tonnage, can ensure larger stable connection and support performance when collision occurs, and has good buffering anti-collision capability.
