Precast concrete manhole cover molds & production tools are specialized precast tool sets for construction component manufacturing, with core functions of shaping concrete components and polishing surfaces. The pouring & polishing in this video is the practical embodiment of their precast production function.
Equipped with standardized molds + electric grinders, they can pour 2-3 covers at a time (each ~50kg), operating via "mold shaping + concrete setting". They adjust pouring dosage by cover size, supporting construction progress.
Divided by purpose into 2 types: Circular molds (fit municipal pipeline openings, for urban roads); Square molds (fit residential drainage openings, for community infrastructure). Operation methods: Batch pouring, single-piece polishing.
Core uses: Municipal road pipelines, residential drainage; Extended to factory sewage, park drainage, underground garage sumps. It provides load-bearing protection (main roads) and anti-slip sealing (sidewalks).
Operated via "mold shaping + concrete hardening" (easy to learn); Key tips: Vibrate to exhaust air when pouring, apply even pressure when polishing. As a core construction tool, it boosts efficiency with efficient shaping & durability.
