The kerb stone is a mark set between the road surface and other structures. Curb stones are generally required between the separation belt of urban roads and the road surface, and between the sidewalk and the road surface. Curb stones are often required at the edge of the central separation belt of the highway, the right edge of the carriageway, or the outer edge of the shoulder.
Curbstones usually come in two forms, one is ordinary concrete prefabrication, the other is stone processing, and they are all impervious materials. The foundation under the curb is generally fine concrete, which is also impervious material. Since the bottom layer of the pavement is a thick, compacted foundation layer, which is an impervious layer, the curb and the underlying foundation are impervious, resulting in the infiltration of water inside the pavement layer or drain through the curb and its foundation. The pavement structure layer and the water at the interface between the surface layer and the base layer cannot be smoothly discharged from the pavement structure, which is one of the inducements of early damage to the pavement. Based on a patented technology, a new type of concrete curb was designed. The new curb stone can drain the water inside the pavement layer, and the cost of the curb stone is not much different from that of the commonly used curb stone.
The curbstone making machine equipment uses sand, industrial waste slag, slag, and slag as the raw material for road tiles. Add a small amount of cement and press it by the roadside stone machine. You can also change the mold to make different types of roadside stones and colored bricks. , Roadside stone bricks, lawn bricks, permeable bricks, special-shaped bricks, etc., suitable for paving roads, highways, squares, highways, improving the urban ecological environment, beautifying the urban environment, and protecting the water and soil from being lost.
