Technology to restore design parameters of irrigation pump discharge pipelines

Abstract The article discusses the restoration of irrigation pump station discharge pipelines’ design parameters, based on sand-cement anticorrosion shotcrete coating technology. Repair of created cracks, damages during operation, and restoration of design parameters of discharge pipelines is performed using shotcreting with Kalmatron® (USA) additive. Besides, paper theoretically validates optimal design data of restored discharge pipelines, the thickness of the anticorrosion coating, and their influence on working characteristics of irrigation pump stations. Theoretical and applied tasks are resolved based on the practical implementation of foreign technology, local supplies, and the use of the Company’s standards at water facilities throughout Uzbekistan’s irrigation systems developed and implemented by the authors of this article.
