Product Description
Grey D400 Drain Cover E600 F900 Round To Square Drain Cover
Square Round Hole Manhole Cover With Spring Lock GB/T23858-2009
GB/T 23858-2009 is China's national standard for "Manhole Covers". It was proposed by the Ministry of Housing and Urban-Rural Development and managed by the Technical Committee for Standardization of Water Supply and Drainage Products. It was issued on May 27, 2009 and implemented on February 1, 2010.
Scope of Application and Basic Framework
Applicable to various types of manhole covers (including round, square, etc.) on urban roads and public places. The standard stipulates term definitions, classification structures, materials, requirements, test methods, inspection rules, and marking, packaging, transportation, and storage content.
Classification and Structure
  • Load-bearing capacity: Divided into A15 (pedestrians/bicycles), B125 (community/light vehicles), C250 (roadside/parking lot), D400 (urban trunk road/heavy vehicles), E600 (port/airport), F900 (heavy industry/special high load) grades
  • Material types: Covering ductile iron, steel fiber concrete, composite materials, etc.
  • Structural form: Includes connection between manhole cover and support, anti-settlement/anti-theft/anti-noise design specifications
Materials and Requirements
For raw materials such as cast iron (spheroidization rate, chemical composition), concrete (strength grade), and composite materials (matrix/reinforcement material performance), the composition and performance parameters are clearly defined.
Performance Requirements
  • Dimensional deviation: Strict limitations on diameter, side length, thickness, and support tolerance
  • Appearance quality: No defects such as cracks and sand holes, with clear patterns/text
  • Bearing performance: Must meet corresponding load requirements with no cracks or deformation after testing
  • Special functions: Anti-theft structures must be stable; anti-settling covers must maintain fit with road surface
Test and Inspection
Includes factory inspection (batch/sampling checks) and type inspection (comprehensive checks for new products). Specifies test methods for load, dimensions, and appearance.
Marking, Packaging and Storage
Manhole covers must be marked with load-bearing level, manufacturer details, and production date. Packaging must prevent damage, and storage must be in dry, ventilated conditions.
