Isango lesinyithi eliyintsimbi liyinxalenye ebalulekileyo yokulawula inqanaba lamanzi kwizakhiwo ze-hydraulic ezifana nesitishi samandla ombane, i-reservoir, i-sluice kunye ne-ship lock. Lifanele lifakwe phantsi kwamanzi ixesha elide, ngokutshintshana rhoqo komile nokumanzi ngexesha lokuvula nokuvala, kwaye lihlanjwe ngokuhamba kwamanzi ngesantya esiphezulu. Ngokukodwa, inxalenye yomgca wamanzi ichatshazelwa ngamanzi, ukukhanya kwelanga kunye nezinto eziphilayo zasemanzini, kunye namaza amanzi, i-sediment, umkhenkce kunye nezinye izinto ezidadayo, kwaye intsimbi kulula ukuyibola, Inciphisa kakhulu amandla okuthwala kwesango lesinyithi kwaye ichaphazela kakhulu ukhuseleko lobunjineli be-hydraulic. Ezinye zikhuselwe yi-coating, ehlala ingasebenzi emva kweminyaka emi-3 ukuya kwe-5 yokusetyenziswa, kunye nokusebenza okuphantsi komsebenzi kunye neendleko eziphezulu zokulungisa.

Ukugqwala akuchaphazeli nje kuphela ukusebenza ngokukhuselekileyo kwesakhiwo, kodwa kudla nabantu abaninzi, izinto kunye nemali ukwenza umsebenzi wokulwa nokugqwala. Ngokwezibalo zezinye iiprojekthi zesango lokutyibilika, inkcitho yonyaka yokulwa nokugqwala kwesango ithatha malunga nesiqingatha seendleko zokugcinwa konyaka. Kwangaxeshanye, inani elikhulu labasebenzi kufuneka lihlanganiswe ukususa umhlwa, ipeyinti okanye isitshizi. Ke ngoko, ukuze kulawulwe ngokufanelekileyo ukugqwala kwentsimbi, kwandiswe ubomi benkonzo yesango lentsimbi kwaye kuqinisekiswe ukuthembeka kunye nokhuseleko lweeprojekthi zokugcina amanzi kunye namandla ombane, ingxaki yexesha elide yokulwa nokugqwala kwesango lentsimbi itsale ingqalelo enkulu.

Indawo yokugqwala kwesakhiwo sentsimbi, isango le-sluice kunye nezinto ezichaphazela ukugqwala:

1. Indawo yokugqwala kwesakhiwo sentsimbi isango le-sluice

Amanye amasango esinyithi kunye nezakhiwo zentsimbi kwiiprojekthi zokugcina amanzi kunye namandla e-hydropower antywiliselwa kumgangatho wamanzi owahlukeneyo (amanzi olwandle, amanzi acocekileyo, amanzi amdaka emizi-mveliso, njl.njl.) ixesha elide; Amanye ahlala kwindawo emanzi neyomileyo ngenxa yotshintsho lwamanzi okanye ukuvulwa nokuvalwa kwesango; amanye aya kuchatshazelwa kukuhamba kwamanzi ngesantya esiphezulu kunye nokungqubana kwesanti, ukungcola okudadayo kunye nomkhenkce; Inxalenye ephezu kwamanzi okanye ngaphezulu kwamanzi ikwachatshazelwa ngumoya ofumileyo wokuphuma kwamanzi kunye nenkungu yamanzi echithekayo; Izakhiwo ezisebenza emoyeni nazo zichatshazelwa kukukhanya kwelanga nomoya. Ngenxa yokuba indawo yokusebenza yesango le-hydraulic imbi kwaye kukho izinto ezininzi ezinefuthe, kuyimfuneko ukuhlalutya izinto ezibangela ukugqwala.

2. Izinto ezibangela ukugqwala

(1) iimeko zemozulu: iindawo zamanzi zesakhiwo sentsimbi isango lokucoca kulula ukulinyazwa lilanga, imvula nomoya ofumileyo.

(2) imeko yomphezulu wesakhiwo sentsimbi: uburhabaxa, umonakalo woomatshini, ukuxinana kwentsimbi, iziphene zokuwelda, izikhewu, njl.njl. zinempembelelo enkulu ekugqwaleni.

(3) uxinzelelo kunye nokuguquguquka: okukhona uxinzelelo kunye nokuguquguquka kukhulu, kokukhona ukubola kusiba kubi.

(4) umgangatho wamanzi: umxholo wetyuwa emanzini acocekileyo uphantsi, kwaye ukugqwala kwesango kuyahluka ngokuxhomekeke kwimilo yeekhemikhali kunye nongcoliseko lwawo; Amanzi olwandle anomxholo wetyuwa ephezulu kunye nokuqhuba kakuhle komoya. Amanzi olwandle aqulethe inani elikhulu le-chloride ions, enokugqwala kakhulu kwintsimbi. Ukugqwala kwesango lentsimbi emanzini olwandle kuyingozi kakhulu kunamanzi acocekileyo.
