Light-emitting porous water-permeable concrete pavement structure

Abstract

The invention relates to a light-emitting porous pervious concrete pavement structure. The structure comprises a porous pervious cement concrete base layer and light-emitting surface layers arranged on the two sides of the upper surface of the porous pervious cement concrete base layer, and the light-emitting surface layers are distributed on the two sides of the upper surface of the porous pervious cement concrete base layer in a grid shape. Compared with the prior art, artificial luminous stone with no radioactivity is used, the structure is composed of an alkaline earth long-afterglow material activated by rare earth elements, and therefore the structure can automatically emit light and is long in light-emitting time. The adhesiveness of the light-emitting layers and the pervious cementconcrete structure is guaranteed through transparent epoxy resin glue, the light-emitting effect is not influenced, and the bonding performance is good; the light-emitting structure layer is of a grid structure, and the light-emitting performance and the mechanical property are ensured while the light-emitting performance is ensured.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a luminescent porous concrete pavement structure. Background technique [0002] In recent years, with the continuous development of urban road traffic, people's requirements for transportation speed and economic benefits have been continuously improved. At the same time, people have paid more and more attention to the research, paving and construction of functional pavements. On the one hand, in order to alleviate urban waterlogging disasters and reduce runoff water pollution, there is an increasing demand for permeable pavement in cities. On the other hand, a luminescent functional pavement that can not only meet the needs of road lighting at night, but also save energy has become the focus of new pavement. [0003] The luminescent pavement is paved with new luminescent materials. A new pavement that can emit light independently is paved on low-grade roads or road sec...

Problems solved by technology

[0004] The current preparation method of luminous pavement, one is to use fluorescent powder to coat the concrete surface, and the other is to spread luminous stone on the concrete surface or use it as aggregate to replace part of the aggregate, forming a road that can absorb light energy and then emit light. Long afterglow material layer, but at the same time there are great defects, the former has low afterglow intensity and short afterglow duration, the pollution caused by phosphor powder to the environment, the latter has low road surface strength and poor durability, and the luminous intensity of the aggregate substitution method is insufficient. high material cost
