El dia 5 de desembre els 22 alumnes del batxillerat tecn\u00f2logic de l\u2019Institut Joan Brudieu van gaudir de la visita a la presa de Rialb a prop de Ponts a la comarca de la Noguera. Aquesta presa \u00e9s una de les m\u00e9s grans de Catalunya amb una capacitat de 402 hm3 i la seva funci\u00f3 \u00e9s abastir l\u2019aigua de boca, regular el cabal del riu\u00a0 Segre per tal d\u2019evitar inundacions aig\u00fces avall i subministrar cabal al canal Segarra-Garrigues.<\/p>\n
Durant la visita l\u2019alumnat va rebre les explicacions dels t\u00e8cnics responsables sobre el procediment de la construcci\u00f3 de la presa, el sistema de regulaci\u00f3 de l\u2019aigua, sistemes de seguretat i turbinaci\u00f3.<\/p>\n
Les seves obres es van iniciar l’abril de 1993, encara de l\u2019any d\u2019abans van tenir lloc tasques de neteja de la zona. Previament es va construir un canal per desviar el curs del riu. \u00c9s tracta d\u2019una presa de gravetat constru\u00efda per blocs, amb 1.200.000 m3 de formig\u00f3 compactat, dels quals s’usaven 5.000 m3 di\u00e0riament. Les excavacions anteriors ja havien suposat el despla\u00e7ament de 950.000 m3 de terra.<\/p>\n
Un cop acabades les obres, vora l’any 2000, van deixar un pant\u00e0 amb capacitat de 402 m3 d’aigua. Durant el transcurs de les obres cal destacar que el formig\u00f3 es tenia que deixar refredar, deixant reposar cada bloc al voltant de 7 dies.<\/p>\n
Aquesta gran construcci\u00f3 compta amb les seg\u00fcents caracter\u00edstiques:<\/p>\n
Quant la central hidroel\u00e8ctrica cal destacar:<\/p>\n
L’embassament\u00a0 tamb\u00e9 compta amb multitud d\u2019elements de control entre els que destaquen: sism\u00f2grafs, p\u00e8nduls, term\u00f2metres,….aix\u00ed com les revisions constants de pr\u00e0cticament cada element de la presa.<\/p>\n
D’altra banda disposa de protocols de seguretat per diferents casos que s’hi poden arribar a donar.<\/p>\n
Des d\u2019aqu\u00ed tamb\u00e9 volem agrair a la Confederaci\u00f3 hidrogr\u00e0fica de l\u2019Ebre i en especial als seus t\u00e8cnics que van fer possible aquesta visita, donant una visi\u00f3 m\u00e9s propera dels conceptes que s\u2019expliquen dia a dia a les aules.<\/p>\n
