Abstract

The invention provides a high-strength road pile. The road pile is cylindrical. The core of the road pile is made of a particle reinforced foamed aluminum base composite. The periphery of the core is coated with an elastic material layer. A copper alloy cylinder is arranged outside the elastic material layer. The external surface of the copper alloy cylinder is coated with an anti-corrosive paint, and a composite foaming agent is used for fully filling and foaming aluminum base alloy to obtain the particle reinforced foamed aluminum base composite. The aluminum base alloy better ensures that a product has a better shock-resistant effect.

Description

technical field [0001] The invention relates to a high-strength road pile and belongs to the technical field of roadblock accessories. Background technique [0002] Barricade is a common name for columnar barricades. It is often made of copper pipe, steel pipe and injection molding. It has good warning, flexibility, and anti-car rolling. It is mainly used for urban intersection lanes, highway maintenance, traffic police law enforcement, road law enforcement, hotels, residential areas, sports venues, and dangerous areas. , road construction sites, etc. The existing road piles have complicated processing technology and poor strength. Contents of the invention [0003] A high-strength road pile, the road pile is cylindrical, the core of the road pile is a particle-reinforced foamed aluminum-based composite material, the core is surrounded by an elastic material layer, the elastic material layer is a copper alloy cylinder, and the outer surface of the copper alloy cylinder i...
