Isango lokufaka amanzi esakhiweni sensimbi liyingxenye ebalulekile yokulawula izinga lamanzi ezakhiweni ze-hydraulic ezifana nesiteshi sikagesi wamanzi, idamu, i-sluice kanye nokukhiya umkhumbi. Kufanele licwiliswe ngaphansi kwamanzi isikhathi eside, ngokushintshana njalo komile nokumanzi ngesikhathi sokuvula nokuvala, futhi ligezwe ngokugeleza kwamanzi okusheshayo. Ikakhulukazi, ingxenye yomugqa wamanzi ithintwa amanzi, ukukhanya kwelanga nezinto eziphilayo zasemanzini, kanye namagagasi amanzi, inhlabathi, iqhwa nezinye izinto ezintantayo, futhi insimbi kulula ukuyigqwala, Yehlisa kakhulu amandla okuthwala isango lensimbi futhi ithinta kakhulu ukuphepha kobunjiniyela be-hydraulic. Amanye avikelwe ngengubo, evame ukwehluleka ngemva kweminyaka emi-3 kuya kwemi-5 yokusetshenziswa, ngokusebenza kahle okuphansi kanye nezindleko eziphezulu zokulungisa.

Ukugqwala akugcini nje ngokuphazamisa ukusebenza okuphephile kwesakhiwo, kodwa futhi kusebenzisa izinsiza eziningi zabantu, izinto ezibonakalayo kanye nezezimali ukwenza umsebenzi wokulwa nokugqwala. Ngokwezibalo zeminye imisebenzi yesango lokugqwala, izindleko zonyaka zokuvimbela ukugqwala kwesango zibiza cishe ingxenye yezindleko zonyaka zokulungisa. Ngesikhathi esifanayo, inani elikhulu labasebenzi kufanele lihlanganiswe ukuze kususwe ukugqwala, upende noma isifutho. Ngakho-ke, ukuze kulawulwe ngempumelelo ukugqwala kwensimbi, kwandiswe isikhathi senkonzo yesango lensimbi futhi kuqinisekiswe ubuqotho nokuphepha kwamaphrojekthi okulondolozwa kwamanzi kanye namandla kagesi, inkinga yesikhathi eside yokulwa nokugqwala kwesango lensimbi idonsele ukunaka okukhulu.

Indawo yokugqwala kwesakhiwo sensimbi isango lokungena kanye nezici ezithinta ukugqwala:

1. Indawo yokugqwala yesango lesakhiwo sensimbi

Amanye amasango ensimbi kanye nezakhiwo zensimbi kumaphrojekthi okulondolozwa kwamanzi kanye namandla kagesi acwiliswe emazingeni ahlukahlukene amanzi (amanzi olwandle, amanzi ahlanzekile, amanzi angcolile ezimbonini, njll.) isikhathi eside; Amanye avame ukuba sendaweni emanzi eyomile ngenxa yokushintsha kwezinga lamanzi noma ukuvulwa nokuvalwa kwesango; amanye azothinteka nokugeleza kwamanzi okusheshayo kanye nokungqubuzana kwendle, udoti oluntantayo kanye neqhwa; Ingxenye ebusweni bamanzi noma ngaphezu kwamanzi nayo ithintwa umoya omanzi wokuhwamuka kwamanzi kanye nenkungu yamanzi agelezayo; Izakhiwo ezisebenza emkhathini nazo zithintwa ukukhanya kwelanga nomoya. Ngenxa yokuthi indawo yokusebenza yesango le-hydraulic imbi futhi kunezici eziningi ezithonyayo, kubalulekile ukuhlaziya izici zokugqwala.

2. Izinto zokugqwala

(1) izici zesimo sezulu: izingxenye zamanzi zesakhiwo sensimbi isango lokungena kwamanzi kulula ukuliguguleka yilanga, imvula kanye nomoya omanzi.

(2) isimo sobuso besakhiwo sensimbi: ubulukhuni, umonakalo womshini, ukugoba, amaphutha okushisela, izikhala, njll. kunomthelela omkhulu ekugqwaleni.

(3) ukucindezeleka kanye nokuguquguquka: lapho ukucindezeleka kanye nokuguquguquka kukhulu, kulapho ukugqwala kuba kubi khona.

(4) ikhwalithi yamanzi: okuqukethwe usawoti emanzini ahlanzekile kuphansi, kanti ukugqwala kwesango kuyahlukahluka kuye ngokwakheka kwamakhemikhali kanye nokungcola kwawo; Amanzi olwandle anokuqukethwe usawoti omningi kanye nokuqhuba kahle komoya. Amanzi olwandle aqukethe inani elikhulu lama-ion e-chloride, okuyinto egqwalisa kakhulu insimbi. Ukugqwala kwesango lensimbi emanzini ahlanzekile kubi kakhulu kunokwamanzi ahlanzekile.
