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:
- Dimensions and elevation in mm.
- Concrete quality ...
- Reinforcing steel quality: ...
- Pipe Steel Quality A106 GR.A or Fe 360 to EuroNorm 25/72
- HE 100 A Steel Quality Fe 360 to EuroNorm 25/72
- Concrete cover to reinforcement 25 mm.
- All steelwork to be shopprimed before installation, in accordance with SP. BN ...
- 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
The next figures show a typical design for the foundation:
