AutoCAD Manhole Blocks

Manhole blocks can be used to drop into your drainage strategy plan to ensure that manholes will not clash with each other. They are a great way to show the differences between manhole chambers (ie foul/storm/catch pit) in your drawing and are colour coded to separate the types.

The manhole block sizes available in this DWG are;

  • 1.2m (Internal Diameter)
  • 1.5m (Internal Diameter)
  • 1.8m (Internal Diameter)
  • 2.1m (Internal Diameter)
  • 2.4m (Internal Diameter)

Choose from any of the sizes above for;

  • Foul Chambers
  • Storm Chambers
  • Catch Pit Chambers

NB: The sizes of these chambers are in respect to the internal diameter of the chamber only. Ensure you check the wall thickness of the chambers you will be installing on site and add this to the internal dimensions to ensure your chambers will not clash on site.
