Permeable kerbstone and preparation method thereof

Abstract

The invention relates to the technical field of road engineering, in particular to permeable kerbstone and a preparation method thereof. The permeable kerbstone comprises a permeable base layer and a permeable surface layer. The permeable base layer is manufactured by bonding single grading rubble. The permeable surface layer is composed of a permeable surface layer top face layer on the top face of the permeable base layer and a permeable surface layer side face layer on the side face of the permeable base layer. The permeable surface layer top face layer and the permeable surface layer side face layer are both manufactured by bonding rubble through bonding agents. The rubble particle size of the permeable base layer is larger than that of the permeable surface layer side face layer. The rubble particle size of the permeable surface layer side face layer is larger than that of the permeable surface layer top face layer. The permeable kerbstone is prepared through the steps of layered mold entering pouring, steam maintenance, drying, squeezing, polishing, demolding and the like. The permeable kerbstone is good in permeable property, impoundment property and water retention, a natural color is adopted, and the effect of ecological environmental protection is achieved; meanwhile, the permeable kerbstone is high in strength, not prone to being broken and good in durability; and the production process can achieve the effect of energy saving and environment protection, and the production technology is simple.

Description

technical field [0001] The invention relates to the technical field of road engineering, in particular to a permeable curb and a preparation method thereof. Background technique [0002] At present, the curbs used in the market are generally concrete curbs or marble curbs. Among them, the concrete curbs are made by off-site prefabrication process, and the marble curbs are made by surface polishing after cutting the original stone. [0003] However, neither the concrete curb stone nor the marble curb stone has the performance of water permeability. Therefore, in rainy and snowy weather, the concrete curb stone or marble curb stone will block the penetration of accumulated water into the ground, which will easily cause the phenomenon of pavement water accumulation . At the same time, neither concrete curbs nor marble curbs have the function of filtering and purifying water. Under the washing of rainwater, sediment will often be lost and pollute the road surface.

[0003] However, neither the concrete curb stone nor the marble curb stone has the performance of water permeability. Therefore, in rainy and snowy weather, the concrete curb stone or marble curb stone will block the penetration of accumulated water into the ground, which will easily cause the phenomenon of pavement water accumulation

At the same time, neither concrete curbs nor marble curbs have the function of filtering and purifying water. Under the washing of rainwater, sediment will often be lost and pollute the road surface.

[0004] In addition, the existing curb stones are usually in a single tone, which is not beautiful enough

Some colored curbstones are also toned by toner, which is easy to fade and not environmentally friendly

[0005] The existing production process of curb stones is traditional, the pollution is relatively large, the production process is not environmentally friendly, and it is not energy-saving
