Kuvakwa kwedhamu remagetsi emvura ndeimwe yemabasa makuru uye akaomarara evanhu, humbowo hwehunyanzvi hweinjiniya uye kuzvipira kusimba rinogara kwenguva refu. Zvivakwa zvikuru izvi hazvingoiti chete kuti mvura isashande; zvinoshandura simba renzizi dzinoyerera kuita magetsi akachena, mwenje yemaguta uye maindasitiri emagetsi. Maitiro ekuvaka rimwe iboka remitambo yezvidzidzo zve geology, mainjiniya ehurumende, nesainzi yezvakatipoteredza.
Danho 1: Chirongwa - Kuronga uye Kugoneka
Kare kare foshoro yekutanga isati yasvika pasi, makore anotsaurirwa pakuronga zvine hungwaru. Mainjiniya, nyanzvi dzezvepasi, uye nyanzvi dzezvakatipoteredza vanoita ongororo dzakakura.
Kusarudzwa kweNzvimbo: Nzvimbo yakakodzera inobatanidza kuyerera kwemvura kwakasimba uye kwakavimbika nenzvimbo yakakodzera, senge mupata wakadzika, kugadzira dziva guru. Dombo riri pasi rinofanira kunge rakagadzikana zvakakwana kuti ritsigire huremu hwakawanda hwedhamu.
Kuongorora Mhedzisiro Yezvakatipoteredza Nemagariro (ESIA): Danho iri rakakosha rinoongorora migumisiro inogona kuitika. Rinogadzirisa kutama kwevanhu munharaunda, kukanganisa nharaunda dzemuno uye kutama kwehove, uye kuchengetedzwa kwenzvimbo dzekare kana dzekare. Nzira dzekuderedza dambudziko iri, dzakadai sekuvaka manera ehove kana kugadzira nzvimbo itsva dzekugara mhuka dzesango, dzinogadzirwa padanho iri.
Dhizaini neUinjiniya: Rudzi rwedhamu rinosarudzwa zvichienderana nehunhu hwenzvimbo yacho. Dhizaini yakajairika idhamu regiravhiti, rusvingo rukuru, rwakatwasuka rwekongiri runovimba nehuremu hwaro kuti rudzivirire kumanikidzwa kwemvura. Rimwe idhamu remugero, rakavakwa nevhu rakamanikana nematombo, rinowanzoshandiswa kumipata yakakura.
Danho rechipiri: Kuisa hwaro - Kugadzirira Nzvimbo uye Kuchinja-chinja
Nehurongwa huripo, shanduko chaiyo yenzvimbo inotanga.
Kugadzirira Nzvimbo: Masango anocherwa, uye nzvimbo yekuvaka inofambika nekuvaka migwagwa nemabhiriji. Nzvimbo yedhamu pachayo inocherwa kusvika padombo rakasimba kuti pave nehwaro hwakasimba.
Kutsauswa kweRwizi: Danho rakakosha pakugadzira nzvimbo yakaoma yebasa. Izvi zvinowanzoitwa nekuvaka migero yenguva pfupi kana migero yakatenderedza divi renzvimbo yekuvaka kuti itsause kuyerera kwerwizi. MaCofferdams—nzvimbo dzenguva pfupi dzisingapindi mvura—akavakwa kudzivirira nzvimbo huru yekuvaka kubva kurwizi rwakatsauswa.
Chikamu chechitatu: Kumuka kweHofori - Kuvakwa Kukuru
Iyi ndiyo danho rinoonekwa zvakanyanya uye rinorema, rinosanganisira kufamba kwezvinhu zvakawanda.
Kudira Konkriti (yeMadhamu Egravity): Kune madhamu makuru ekonkriti akadai serudzi rwegravity, kuvakwa kunoitika muzvikamu zvakasiyana, zvinobatana. Mapaipi ekutonhodza anoiswa mukonkriti kuti agadzirise kupisa kunobva panguva yekuoma, kudzivirira kuputika kunogona kukanganisa kunaka kwechivako. Maitiro aya anoenderera mberi uye anogona kutora makore akati wandei.
Kuvakwa kweDombo (reMadhamu ePasi/Matombo): Zvidimbu zvevhu risingapindi mvura nematombo akamanikana zvinoiswa zvakarongeka uye zvinokungurutswa kuti pave nepakati pakaoma, pasingapindi mvura. Nzira iyi inoda kuti zvinhu zvigare zvichiwanikwa kubva kumagwenga ari pedyo.
Kugadzirwa kweSpillway: Panguva imwe chete, vharuvhu yekudzivirira mvura inoyerera, iyo inovakwa. Chivako ichi chinobvumira mvura yakawandisa kuti ipfuure dhamu zvakachengeteka panguva yemvura zhinji, zvichidzivirira dziva kuti risapfuure mvura zvichikonzera kukuvara kukuru.
Chikamu chechina: Mwoyo weSisitimu - Kuiswa kwePowerhouse
Sezvo dhamu richikwira, basa rinotanga pamagetsi.
Mapombi ePenstock: Mapaipi makuru esimbi anoiswa nepakati pedhamu kana kuti akakomberedza, akagadzirirwa kufambisa mvura kubva mudhamu nesimba guru.
Maturbine neMajenareta: Mukati meimba yemagetsi, mapenstock anonangidzira mvura pamashizha ematurbine makuru, zvichiita kuti atenderere. Maturbine aya akabatana nemajenareta, ayo anoshandura simba remuchina kuita simba remagetsi. Rudzi rwakajairika iFrancis turbine, iyo inoshanda zvakanaka pakuyerera kwemvura kwakasiyana-siyana uye kumanikidzwa.
Danho rechishanu: Kusungwa uye Kutumirwa Kwebasa
Kana chivakwa chikuru chapera uye maturbine aiswa, nguva yechokwadi inosvika.
Kuvharirwa: Migero yekutsausa mvura inovharwa zvishoma nezvishoma, uye rwizi rwunotanga kuzadza dziva riri kuseri kwedhamu. Maitiro aya anononoka uye anotariswa nokungwarira, sezvo mvura iri kukwira ichiisa simba pachivako chitsva kekutanga.
Kushanda: Sezvo dura rinosvika padanho rekushanda, mvura inoburitswa kuburikidza nepamatangi kuti itenderedze maturbine. Majenareta anosanganiswa negrid yemagetsi, uye chirimwa chemagetsi chinotanga kupa magetsi zviri pamutemo.
Nhaka yeSimba uye Mutoro
Kupedzwa kwedhamu remagetsi rinoshandisa mvura ibudiriro huru. Rinopa simba rinogara kwenguva refu, rinogona kushandiswazve, rinoderedza kuvimba nemafuta epasi, uye rinogona kupa zvimwe zvinobatsira zvakaita sekudzora mafashamo, kudiridza, uye kuzorora.
Zvisinei, hazvisi pasina kuchinjana kwakakura. Mhedzisiro yezvakatipoteredza nemagariro evanhu—kubva kunharaunda dzakachinjwa kusvika kunharaunda dzakadzingwa—yakakura uye inogara kwenguva refu. Nokudaro, kuvaka madhamu emazuva ano kunosanganisira kuronga nekudzivirira matambudziko pamwe chete neunyanzvi hweinjiniya. Dhamu remagetsi rinogadzirwa zvakanaka rinomira sechiratidzo chekugona kwedu kushandisa simba rezvisikwa, richitiyeuchidza nezvekuenzanisa kwakanaka pakati pekufambira mberi nekuchengetedza.
