Application Scenarios
1. Municipal Public Areas
City Roads
Installed beneath roadways and sidewalks, protecting underground water meters, stopcocks, and valves, ensuring the stable operation of the urban water supply system.
Parks and Green Belts
Hidden beneath walkways or lawns, they do not affect the aesthetic appearance of the landscape and facilitate regular maintenance of water supply equipment by maintenance personnel.
Commercial Districts
In pedestrian streets and shopping areas with high pedestrian traffic, they provide a safe and stable walking surface while facilitating quick maintenance of water supply facilities.
2. Residential Communities and Living Areas
Residential Communities
Embedded in the ground in front of apartment buildings or in green belts, protecting residents' water meters, preventing damage from external forces, and facilitating meter reading and maintenance by property management or water supply departments.
Schools and Hospitals
Installed under roads on campuses and hospital grounds, ensuring stable daily water supply for teachers, students, and patients, and avoiding safety hazards caused by protruding manhole covers.
Renovation of Old Residential Areas
Used as an upgrade to replace old manhole covers, improving the safety and durability of water supply facilities and reducing maintenance costs.
3. Industrial and Commercial Parks
Industrial Parks
Used in factory roads, workshop entrances, and other locations, withstanding the pressure of heavy vehicles such as forklifts and trucks, protecting industrial water supply pipelines and metering equipment.
Logistics Parks
Suitable for scenarios with high-frequency truck traffic, preventing manhole cover collapse or displacement, ensuring the safety of both logistics transportation and the water supply system.
Commercial Complexes
Installed in underground parking lots and plaza grounds, balancing traffic load-bearing capacity and equipment protection, meeting the water supply operation and maintenance needs of large commercial complexes.
Maintenance Procedures
Regular inspection
Check the fit between the cover plate and the manhole frame every 6-12 months to prevent loosening or displacement.
Cleaning and maintenance
Promptly clean dirt, sand, and debris from the surface of the cover plate to prevent clogging of drainage holes.
Anti-corrosion treatment
If the coating is found to be peeling off, immediately apply anti-rust paint to prevent the cast iron from rusting.
Emergency handling
If the cover plate is damaged, it must be replaced immediately to prevent pedestrians and vehicles from falling into the manhole.
Production process
Mold Making: Customized sand molds are created according to customer requirements, ensuring precise dimensions and markings.
Cast Iron Melting: Ductile cast iron raw materials are melted in a medium-frequency furnace, with the composition controlled to guarantee material properties.
Casting and Forming: Molten iron is poured into the sand mold, and after cooling, the casting is removed from the mold.
Grinding and Cleaning: Flashing and burrs are removed from the casting, and surface defects are repaired.
Anti-corrosion Coating: Hot-dip galvanizing or epoxy asphalt coating is applied to enhance corrosion resistance.
Testing and Packaging: Load pressure testing and visual inspection are performed, and qualified products are packaged and stored.
