El Salto Dam (Spanish: ''Presa El Salto''), located on the Guadalquivir River in the municipal district of El Carpio (Province of Córdoba, Spain), comprises a dam and its corresponding hydroelectric power station. The dam is situated near the 3.3 kilometer mark on the Pedro Abad-Adamuz highway (CO-412). Its Neo-Mudéjar design is the result of a collaboration between architect Casto Fernández Shaw and engineers Carlos Mendoza and Antonio del Águila. The Madrid-based engineering consulting firm undertook construction of the dam between 1918 and 1922. Since its inception, the dam has proved valuable to the local population for its contribution to the development and economic expansion of the area. == Design == Built on the site of some old water mills, the dam creates a grade in the riverbed through the use of two abutments, one on each bank of the river, and five interior buttresses. The buttresses, which sustain the bridge and the six sluice gates, also hold up the metal structure bearing the machines that operate the gates. The abutment on the right bank forms an arched portal over the roadway and houses the access stairway to the control room, whose crowning octagonal turret once bore a dome. This dome, the horseshoe arch and alfiz, the simple and double windows, and the handrail supports all belong to the Neo-Mudéjar style. The entire concrete structure is covered with a facing of blocks in imitation of stretcher and header bond masonry. The upper metal structure, a lattice box girder, initially held a wooden platform that has since been replaced by a grate. The motors that power the gears and chains used to raise the sluice gates are housed here in protective casings. A traveling bridge crane projects from the upstream side of the girder. From within its two-story wooden cabin, the operator is able to stack metal beams in slots parallel to the sluice gates in order to retain the water and allow the gates to be isolated. The crane is also used to lift motor and gear assembly casings. In addition to its carefully designed mechanisms, the dam has an important artistic value and is in a good state of preservation. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「El Salto Dam」の詳細全文を読む スポンサード リンク
