GROUND SETTLEMENT

Ground settlement e.g. where a pipe leaves an underground structure, can be accommodated by a pair of KLAMFLEX Couplings.

All pipe trenches are of necessity excavating below the invert to allow for pipe bedding. Where this bedding is to be flexible, e.g. granular fill, some settlement of the pipe will inevitably occur when it is backfilled. To relieve pipe stresses, Coupling A should be installed as close to the structure as possible. Coupling B permits pipe C to angulate, taking up settlement Y. The length of pipe C is determined as in above diagram, though its structural strength in bending must be considered.
