Abstract

The present study focuses on the design of an intake system with bottom racks and supercritical approach, to be implemented in the existing steeped channel of the Hydraulics Teaching Laboratory (LDH) of the Escuela Politécnica Nacional (EPN). The proposal consists of dimensioning intake and diversion elements, considering the geometric characteristics of the steeped channel, such as its 100% slope and length of 3.84 meters. The hypotheses established for this project were the flow is supercritical before and after the interception, and the maximum flow that circulates through the steeped channel will be collected. These criteria were fundamental for the design of the elements of the intake system. The main elements of the proposed intake system include a bottom rack, a collection channel (gallery) and a discharge vortex that acts as an energy dissipator. Two implementation alternatives have been proposed, each with detailed Class IV budget and floor design drawings. For the design of these alternatives, the base information from previous studies carried out at the LDH was used. To verify the dimensions, a planimetric survey was carried out. Finally, the technical and economic feasibility of implementing this collection system in the LDH is analyzed.
