Cement brick highway slope protection brick laying cement tile 1: Sidewalks original soil compaction, leveling small square brick plastic mold, the density is higher, but also add weight lane gravel layer, busy sidewalks 100-150mm thick plastic mold light 150-200mm thick lanes, truck lanes 200-300 thicker than the thickness depends on the load. 2: The sand bed to play Pinto square brick sidewalk brick circular plastic mold sector, the decomposition pressure, drainage role in the sand as well, 25-40mm thick, and be compacted and smooth. 3: the tiles flat on the sand bed, according to the design pattern laying and retention sand sand to full fill the gaps in general can be. Fluid Polishing Fluid Polishing is to rely on high-speed flow of the liquid and carry abrasive scouring surface to achieve the purpose of polishing. Common methods: abrasive jet machining, liquid jet machining, hydrodynamic grinding. Hydrodynamics attrition is driven by hydraulic fluid carrying the abrasive medium speed reciprocating flow through the workpiece surface. Mainly in the lower pressure medium flowing through good special compound (polymer-like substance) and mixed with abrasive made of silicon carbide abrasive powder can be used.
