Design standard for so-called sleepers in pipe ways. The sleepers are the alternative to a pipe bridge when supporting piping in pipeways. Use this standard for study purposes only.


Notes for the below figures:

  1. Dimensions and elevation in mm.
  2. Concrete quality ...
  3. Reinforcing steel quality: ...
  4. Pipe Steel Quality A106 GR.A or Fe 360 to EuroNorm 25/72
  5. HE 100 A Steel Quality Fe 360 to EuroNorm 25/72
  6. Concrete cover to reinforcement 25 mm.
  7. All steelwork to be shopprimed before installation, in accordance with SP. BN ...
  8. The top elevation of the sleeper can be adjusted by passing a piece of rebar through the hole in the post and by installing shims between this bar and the top of the footing

Design criteria:

  • piping load = 150 kg/m2
  • span = 600 mm
  • D is equal or smaller: 2500 mm
  • C is equal or smaller: 0.4 * D mm
