Technical Field

The invention relates to a self-luminous curb based on solid wastes and a preparation method thereof, belonging to the technical field of road engineering structures and road engineering materials.

Background

The kerbstone is a boundary marking stone which is paved on the edge of a road surface and used for marking the boundary of the road surface, and not only can play a good role in protecting the edge of the road surface, but also can play a role in inducing driving sight and intercepting and gathering rainwater in the road surface. The kerbstone has various forms, including a vertical type, an inclined type, a flat type and the like. The existing kerbstone is generally made of cement concrete prefabricated blocks, cut natural stones and the like. In recent years, with the continuous enhancement of the policy of ecological environment protection in China, the exploitation of stone materials is strictly limited, the price is continuously increased, and the utilization of natural stone curb stones is less and less. At present, most of roads in China use the kerbstone which is a cement concrete precast block kerbstone.

With the rapid development of national economy, a large amount of solid waste is brought, wherein waste glass and tailings are main solid waste products in the solid waste, so that the environment is polluted, and waste glass fragments have certain dangerousness and are easy to cut; the tailings are piled up like a mountain, occupy a large area of cultivated land and are difficult to be properly treated, so that secondary pollution is caused.

The vast majority of roads and village roads in China have no night illumination, the driving sight distance is short, the vision field is narrow, drivers only depend on the conditions of vehicle lights, light reflecting facilities and the like, the road surface barriers and the road edges are difficult to see clearly, and traffic accidents are easy to happen. According to statistics, the accident rate of road driving at night in China is more than 1.5 times of the accident rate in the daytime, the life and property safety of people is damaged, and huge economic loss is caused. In urban roads, kerbs at rain mouths, road turns, important road sections strictly prohibited from parking, and the like are coated in yellow, and kerbs at fire fighting passages are coated in red, so that pedestrians and vehicles can observe conveniently, and driving safety is guaranteed. But in the case of insufficient lighting at night, this information is difficult to be found. The reason is that the reflection coefficient of common concrete and stone kerbs to light is 0.2-0.3, so that pedestrians and drivers can hardly see the road edge clearly under the driving condition at night. Moreover, the coatings are easy to peel off and fall off, and the use function is influenced.

The luminous concrete curb stone is characterized in that luminous components are added in curb stone concrete, the luminous concrete can provide good lane demarcation and driving visual field for pedestrians and drivers at night or in an environment with poor light conditions, certain illumination can be provided at night in urban roads, information such as warning and prohibition can be provided, the drivers can be warned in roads, particularly at bends and sharp downhill slopes, and the occurrence of traffic accidents is reduced. Therefore, research and development and application of related materials have important social significance and economic value for improving traffic safety and emergency guarantee of roads.

However, the existing luminous concrete curbs have some problems. For example, the most common luminous concrete curb is a luminous concrete which is coated on the surface layer of a concrete strip by adopting a luminous layer, or a fluorescent substance is sprayed on the surface layer of the concrete strip, or a cement-based material is directly mixed with fluorescent powder to prepare the luminous concrete curb, so that the luminous function of the curb is realized, but the curb has the problems of luminous layer or surface luminescence only, weak local luminous brightness and short luminous time, and the luminous layer, the coated fluorescent substance or the surface luminescence part are easy to wear and even fall off after being used for a period of time or impacted, so that the luminous function of the luminous concrete curb is greatly weakened, even the luminous function is lost.

For example, chinese patent document CN111501603A discloses a light-emitting road curb comprising: the interior of the kerbstone body is provided with a power supply preformed hole facing a luminous road surface, and the energy compensator is arranged outside the power supply preformed hole of the kerbstone body and is an excitation light source with the light intensity of more than or equal to 25 LX; and the power supply device is connected with the energy supplementing device through the power supply preformed hole and provides power for the energy supplementing device. The luminous concrete curb that this patent provided shines through electric power, has the service condition height, to the harsh problem of environmental requirement, in case devices such as power or energy supplement ware break down can lead to whole curb to lose luminous function.

The inventive example produced a luminescent concrete curb having a size of 99cm by 15cm prismatic structure.

Test examples

The curbs prepared in examples 1, 2, 3 and comparative example were placed under a light source with an illuminance of 230lux (indoor illuminance) for 12 hours, and then placed in the same dark environment, and after waiting for 8 hours, the light emission luminance was measured, respectively.

The light-emitting luminance of the self-luminous curb prepared in example 1 was 0.43cd/m²The luminance of the self-luminous curb prepared in example 2 was 0.17cd/m²The luminance of the self-luminous curb prepared in example 3 was 0.15cd/m²The luminescent concrete curb prepared in the comparative example had a luminescent brightness of 0.05cd/m²。

The curbstones prepared in examples 1, 2 and 3 and the comparative example were placed in a light source (direct sunlight illumination outside a clear day) with an illumination of 100000lux for 30min, and then placed in the same dark environment, and after waiting for 8h, the light-emitting brightness was measured respectively.

The luminance of the self-luminous kerbstone prepared in the embodiments 1, 2 and 3 is 2.3-3.8 cd/m²The luminous intensity of the luminous concrete curb prepared by the comparative example is 0.02-0.20 cd/m²。

From the data, firstly, the self-luminous curbs prepared in the examples 1, 2 and 3 can still reach the luminous brightness of 2.3-3.8 cd/m2 after being continuously irradiated by sunlight for 30min and placed in a dark environment for 8h, which is 11-189 times that of the comparative example, and the luminous effect at night is far stronger than that of the luminous concrete curbs prepared in the comparative example 1. The lowest brightness of human eyes is 0.32mcd/m2, and the brightness of the self-luminous curb prepared in the embodiments 1, 2 and 3 is 2.3-3.8 cd/m2, so that the self-luminous curb can be distinguished by eyes at night. Secondly, the cement-based material and the fluorescent powder are mixed together in the comparative example 1, and because the cement-based material is not transparent, the concrete finished product only has surface luminescence, and simultaneously, a large amount of luminescent materials are used, so that the cost is increased. The invention adopts a split structure and is formed by splicing the concrete base stone and the luminous stone, thereby optimizing the formula of the self-luminous material, greatly reducing the use of the luminous material, effectively reducing the cost, and avoiding the problems that the luminous concrete curb only has surface luminescence and the luminous layer is easy to wear and even fall off because the luminous stone integrally emits light.
