Abstract
The utility model discloses a multilayer-filled aqueduct bent anti-collision device, relates to an aqueduct bent anti-collision device, and aims to solve the problems that no anti-collision measures exist and the protection measures are insufficient when the current collision damage of impactors such as vehicles to aqueduct bent is caused. The utility model provides an aqueduct framed bent buffer stop that multilayer was filled includes that the hoop is around 3 polyethylene square pouring jacket of framed bent, and pouring jacket edges and corners department is convex structure, the pouring jacket is polyethylene cystosepiment, polyurethane blotter, polyethylene grid respectively from inside to outside filler, and the grid is inside to constitute square cavity structure by vertically and horizontally staggered's grid, adopts bolted connection between grid and the main tank, through the special glue adhesion of PE between polyethylene cystosepiment and the framed bent. The utility model relates to an aqueduct bent frame anti-collision device with a recyclable collection sleeve and filling materials.
Description
Technical Field
The utility model relates to the technical field of aqueduct bent frame collision avoidance, in particular to an aqueduct bent frame collision avoidance device with multilayer filling.
Background
As the accident that the vehicle and the ship impact the aqueduct bent frame frequently occurs, the damage to the aqueduct structure can be caused while the life and property loss is caused to the personnel, and the important mode for protecting the safety of the aqueduct bent frame structure is to set up an anti-collision measure. At present, a self-floating anti-collision device is arranged on an aqueduct section with navigation requirements, an aqueduct anti-collision facility on a highway section mainly takes active protection as a main part, the active protection mainly prompts a driver in the forms of safety warning and the like to prevent traffic accidents, passive anti-collision measures follow pier anti-collision technology, and anti-collision piers are arranged on materials such as steel, plastics or rubber.
Disclosure of Invention
In order to solve the problems of poor protection effect and difficult maintenance of the conventional aqueduct bent frame anti-collision facility, the utility model provides the aqueduct bent frame anti-collision device filled in multiple layers, which consists of sleeve boxes filled with different materials, can improve the bidirectional protection performance of the device, has the characteristics of easy disassembly and recycling, and can better maintain the stability of a bent frame collision process.
The technical scheme adopted by the utility model for solving the technical problem is as follows: the utility model provides a aqueduct framed bent buffer stop that multilayer was filled includes that the hoop centers on 3 polyethylene square pouring jackets of framed bent, and pouring jacket edges and corners department is convex structure, the pouring jacket is polyethylene cystosepiment, polyurethane blotter, polyethylene grid respectively from inside to outside filler, and the grid is inside to constitute square cavity structure by vertically and horizontally staggered's bars, adopts bolted connection between grid and the main tank, through the special glue adhesion of PE between polyethylene cystosepiment and the framed bent, reaches the purpose that effectively resists vehicle impact effect.
The utility model has the advantages that the energy absorption effect of the device can be better improved by the aid of the multi-layer filled anti-collision materials, the anti-collision materials are filled into the sleeve box, so that the device is easy to disassemble and can be recycled, the edges and corners of the sleeve box are subjected to arc treatment to reduce lateral impact force, and the main box is of a flexible grid structure, so that the aqueduct bent is protected, and meanwhile, a driver is protected.
