Abstract:
The paper presents an analysis of the rehabilitation directions for the pipe network from irrigation plots used for
aspersion watering. The rehabilitation and modernisation of the pipeline network is differentiated on the structural
components: main pipelines - secondary - distribution, hydrants, hydraulic installations, anchorage blocks,
undercrossing, overcrossing etc. The case study was drawn up for an sprinkler irrigation plot network, Doniceasa-Falciu
Plot 7, Vaslui County. Tertiary irrigation pipes are fed by single-line pumping stations located in the canal. The
discharge pipe of the pumping unit is made of 200 mm diameter steel. The tertiary irrigation pipe with a length of 1020-
1400 m is made of asbestos and PVC-G with decreasing diameter from 200 mm to 125 mm for Q = 70-95 l/s and P =
6,50 - 7,50 bar. The pipeline has irrigation hydrants with diameters of 100 mm and 150 mm. The rehabilitation process
of the pipeline network is based on a hydraulic and resistance calculation abstracts. The paper presents rehabilitation
options for the pipes from the sprinkler irrigation plot.
