The article discusses issues related to the use of
polyethylene double-layer corrugated pipes “CORSIS” of
large diameter in the reclamation industry as discharge
and conducting manifolds instead of some conducting
channels. This reduces the contours of the fields being
processed. The most significant factors are noted – the
length of the run, the configuration or relief of the field
areas, affecting the productivity of agricultural machines.
The most rational sizes of the fields to be processed
are recommended. The hydraulic characteristics of the
“CORSIS” pipes of 200, 315, 400 and 500 mm diameter
examined and the possible drainage areas with the
use of polyethylene double-layer corrugated “CORSIS”
pipes as conducting and drainage manifolds with partial
replacement of some channels are given. It has been
found that if the slopes are greater than 0.001 and the fill
degree h/dis greater than 0.3, all pipelines provide nonbinding flow rates.
