Problems solved by technology

[0002] With the rapid development of my country's economy, the development of road traffic is becoming more and more extensive, but the road traffic safety in relatively remote villages and mountainous areas is poor, and the accident rate is high
The isolation and guide barriers in these places are usually made of stone or plastic or metal. The aging and brittleness of plastic and the corrosion of metal will easily cause the barriers to have poor weather resistance and short service life. The above-mentioned roadblocks are light and easy to carry and move, and are mainly used for the isolation of pedestrians or as a warning for low-speed vehicles in the city, which cannot fully guarantee traffic safety; most roadblocks are difficult to distinguish at night or in dark environments, although CN 203462410 is designed There is a reflective tape, but it is easy to peel off or be damaged, while the lumi

Abstract

The invention discloses a fiber toughened recycled high-performance concrete self-luminous roadblock which is divided into an inner part and an outer part, wherein the inner part is steel fiber toughened recycled concrete, and the outer part is a polymer waterproof mortar protective layer doped with an energy storage luminous material; the steel fibers introduced into the steel fiber toughened recycled concrete are steel fibers connected into a row by hydrosol; and the energy storage luminescent material is rare earth aluminate. The fiber-toughened recycled high-performance concrete self-luminous roadblock has the characteristics of better toughness, impact resistance and durability; cyclic utilization of environment-friendly self-luminous materials and waste concrete is an important way for realizing green sustainable development of building materials, and the fiber-toughened recycled high-performance concrete self-luminous roadblock has good economic benefits and social benefits.

Description

technical field [0001] The invention relates to road administration equipment for controlling road traffic, in particular to a fiber-toughened recycled high-performance concrete self-luminous roadblock. The roadblock belongs to the field of road traffic facilities. Background technique [0002] With the rapid development of our country's economy, the development of road traffic is becoming more and more extensive. However, the road traffic safety in relatively remote villages and mountainous areas is poor, and the accident rate is relatively high. The isolation and guide barriers in these places are usually made of stone or plastic or metal. The aging and brittleness of plastic and the corrosion of metal will easily cause the barriers to have poor weather resistance and short service life. The above-mentioned roadblocks are light and easy to carry and move, and are mainly used for the isolation of pedestrians or as a warning for low-speed vehicles in the city, which cannot ...
