3. CARES FOR BEDDING
Before bedding the DEBITFLO in concrete, follow these recommendations to avoid any deformation inside the channel and
unbalanced channel parts.
- The strengthening pieces are sufficient to keep optimal all dimensions of the channel during stocking and transport.
- These strengthening pieces are not designed to resist with the pressure due to materials (concrete, sand, foams, etc.) during bedding.
- Therefore, it is necessary to adapt bracing device, internal wood struts to balance the pressure from bedding materials and avoid
restrictions/surface defects in the channel.
- Until all the materials are stabilized, dried, keep all the original strengthening pieces in place.
- Steel frameworks are of a good help for huge channels: drill into the external wood strengthening pieces to fix the channel to the structure.
- First bedding the ends of the channel and bottom of each strengthening pieces assure to keep a good position when filling is
done with sand or weak concrete.
No respect of these recommendations will cancel the manufacturer warranty.
UPSTREAM FINISHING
Coupling of DEBITFLO and input channel should be done of concrete, avoiding sudden changes of dimensions.
DOWNSTREAM FINISHING
Coupling of DEBITFLO and output line should be done of concrete, keeping a freely falling.
