Rainwater culvert pipe mold are industrial molds specifically engineered for producing concrete culverts used in municipal stormwater drainage systems. Designed to manufacture culverts with plain-end, socket-end, or flanged-end joints, these molds ensure structural strength, sealing integrity, and compressive resistance. They are suitable for urban underground utility tunnels, road drainage systems, and agricultural irrigation projects.
Usage
Designed for prefabricating concrete stormwater culverts, applicable to urban drainage systems, highway/railway culverts, and river rehabilitation projects, enabling high-capacity drainage and flood prevention.
Key Applications
Municipal engineering
Urban underground utility tunnels, stormwater harvesting systems
Transportation infrastructure
Expressway / railway drainage culverts
Water conservancy
River diversion channels, flood storage zones
Sponge City initiatives
Ecological retention ponds, permeable trench systems
