Abstract
El riego es uno de los factores prioritarios para lograr rendimientos satisfactorios de los cultivos, razón por el cual se debe establecer una adecuada infraestructura de riego, que permita mínimas infiltraciones, el canal de riego El Conde actualmente es de material rústico, existiendo pérdidas de agua por infiltración, debido a estos problemas y con la finalidad de que los 15 usuarios con 214 Has cuenten con el suministro del agua adecuadamente, se diseñó el mejoramiento de la línea de conducción del canal de riego entre la progresiva Km 0+000 al Km 2+000, para ello se ejecutó un estudio de mecánica suelos, un estudio hidráulico y estructural de la línea de conducción y un estudio topográfico en campo; por otro lado, se realizó también el estudio estructural e hidráulico de las obras de arte y además se obtuvo los costos y presupuestos de la infraestructura planteada. Para la investigación se utilizó el método transversal descriptivo, obteniéndose información directa e indirecta a través de un levantamiento topográfico perimétrico y altimétrico, en el estudio de suelos se tomaron muestras de suelo a través de calicatas a una profundidad de 1.20 m, cada 500 m a lo largo del canal de riego, para el diseño hidráulico y estructural de la línea de conducción se utilizó la ecuación de Mannig y se eligió una sección transversal trapezoidal, además se verificó la falla del concreto por asentamiento y comparación del momento de volteo - resistente y esfuerzos de tracción y compresión. El suelo analizado presenta una clasificación en su mayoría SC, con un peso específico de 1700 Kg/cm3 y capacidad portante de 0.9 Kg/cm2. Para el diseño hidráulico se tuvieron 5 tramos con pendientes de 0.0035 m/m , 0.002 m/m y 0..001 m/m, un caudal de 0.48m3/seg, la sección transversal fue una base de 0.50 m, tirante 0.44 m, borde libre 0.21 m y talud de 0.80, revestido con concreto simple de f´c= 175 Kg/cm2. Las obras de arte consideradas fueron una alcantarilla tipo cajón con un ancho interno de 0. 8 m y altura de 0.75 m, con un espesor de paredes y losas de 0.20m, revestido con concreto armado f´c= 210 Kg/cm2., y 5 tomas laterales con compuerta metálica deslizante. El presupuesto ascendió a S/. 584,736.68 .
ABSTRACT Irrigation is one of the priority factors to achieve satisfactory crop yields, which is why an adequate irrigation infrastructure must be established, which allows minimal infiltration, the El Conde irrigation canal is currently made of rustic material, with water losses due to infiltration, due to these problems and in order that the 15 users with 214 Has have adequate water supply, the improvement of the irrigation canal conduction line was designed between the progressive Km 0 + 000 to Km 2 +000, for this, a soil mechanics study, a hydraulic and structural study of the conduction line and a topographic study in the field were carried out; on the other hand, the structural and hydraulic study of the works of art was also carried out and the costs and budgets of the proposed infrastructure were also obtained. For the research, the descriptive cross-sectional method was used, obtaining direct and indirect information through a perimetric and altimetric topographic survey, in the soil study, soil samples were taken through pits at a depth of 1.20 m, every 500 m of the conduction line, for the structural and hydraulic design of the conduction line, the Mannig equation was used and a trapezoidal cross section was chosen, in addition, the failure of the concrete was verified by settlement and comparison of the turning moment - resistant and stresses of traction and compression. The soil analyzed presents a classification mostly SC, with a specific weight of 1700 Kg / cm3 and a bearing capacity of 0.9 Kg / cm2. For the hydraulic design there were 5 sections with slopes of 0.0035 m / m, 0.002 m / m and 0..001 m / m, a flow of 0.48m3 / sec, the cross section was a base of 0.50 m, tie 0.44 m, free edge 0.21 m and slope of 0.80, lined with simple concrete of f´c = 175 Kg / cm2. The works of art considered were a box-type culvert with an internal width of 0.8 m and a height of 0.75 m, with a wall and slab thickness of 0.20 m, lined with reinforced concrete f´c = 210 Kg / cm2., And 5 side intakes with sliding metal gate. The budget amounted to S /. 584,736.68.
