Estudio y rediseño del sistema de tuberías de distribución del agua de riego de la zona TB 11 de las parroquias San Luis- Maldonado-Cubijíes del cantón Riobamba

Abstract

The objective of this work was to study and redesign the irrigation water distribution piping system of the TB11 zone of the San Luis - Maldonado - Cubijíes parishes, in Riobamba canton. The TB11 irrigation system was evaluated by direct observation and information was collected on the current status and technical data of all components to establish the initial hydraulic situation through Manning's equation. The hydraulic calculations included flow and velocity values and, finally, head losses of 99.44 m.c.a., and proposed trajectories for the branches of reservoirs 65 and 67B, considering two alternatives in which qualitative (length of pipe and possibility of building houses) and hydraulic (head losses) aspects were evaluated. Also, signage was placed and made under the INEN878:2013 standard for 11 selected locations along the pipeline route. Subsequently, the pipeline was redesigned based on Manning's equation where the new diameters and flow rates with which the system will correctly supply each reservoirwere obtained.Amaintenance listwas also prepared with immediate corrective actions and visual inspections for the proper functioning of the release valves, air valves, interconnection valves, and butterfly valves. Finally, a budget estimate was made for the implementation of the new TB11 piping system which resulted in $ 3' 650 808, 00 US dollars.
