Crash barriers are used on highways and bridges, and the central median barriers on highways are also made using crash barrier molds. The crash barriers used on highways are typically 4 meters in length, which facilitates faster construction. Due to road variations, the styles of mold equipment differ, so specific production designs are required.
The surface of crash barrier molds is smooth and flawless, producing mold bricks with high hardness and a superior surface. Concrete barrier molds are sheet metal molds used for producing barriers, formed by pressing, bending, and welding steel plates. These molds are detachable and are filled with concrete and steel reinforcement frames to create barriers. These barriers come in various sizes and are primarily used for median and edge isolation on highways, separating bidirectional lanes, and isolating pedestrians from motor vehicles. The surface of cement products can be painted to indicate their purpose. Concrete barrier molds, made from steel, allow for two demoldings per day. After assembly, concrete and steel reinforcement frames are placed inside the molds, and vibration platforms are used for shaping. The molds are then placed in a shaded area for natural curing until the cement sets, after which the molds are removed, completing the prefabrication process of barrier blocks. The production process of barrier steel molds is simple and user-friendly, significantly improving construction efficiency.
