Ulwakhiwo lwentsimbi isango le-sluice licandelo elibalulekileyo lokulawula inqanaba lamanzi kwizakhiwo ze-hydraulic ezifana nesikhululo sombane wamanzi, idama, isluice kunye nokutshixwa kweenqanawa. Kufuneka ifakwe ngaphantsi kwamanzi ixesha elide, kunye nokutshintshwa rhoqo okomileyo kunye nokumanzi ngexesha lokuvula kunye nokuvala, kwaye ihlanjwe ngamanzi ahamba ngesantya esiphezulu. Ngokukodwa, inxalenye yomgca wamanzi ichatshazelwa ngamanzi, ukukhanya kwelanga kunye nezinto eziphilayo zasemanzini, kunye namaza amanzi, intlenga, umkhenkce kunye nezinye izinto ezidadayo, kunye nentsimbi kulula ukubola, Inciphisa kakhulu umthamo wokuthwala isango lentsimbi kwaye ngokunzulu. ichaphazela ukhuseleko lobunjineli be-hydraulic. Ezinye zikhuselwe ngokutyabeka, okusilela ngokubanzi emva kweminyaka emi-3 ukuya kwemi-5 yokusetyenziswa, kunye nokusebenza okuphantsi kunye neendleko eziphezulu zokugcinwa.

I-Corrosion ayichaphazeli kuphela ukusebenza ngokukhuselekileyo kwesakhiwo, kodwa iphinda idle abantu abaninzi, izinto eziphathekayo kunye nezibonelelo zemali ukwenza umsebenzi wokulwa nokubola. Ngokweenkcukacha-manani zezinye iiprojekthi ze-sluice gate, inkcitho yonyaka ye-akhawunti yokuchasana nokubola kwesango malunga nesiqingatha seendleko zonyaka zokugcinwa. Ngelo xesha, inani elikhulu labasebenzi kufuneka lihlanganiswe ukususa i-rust, ipeyinti okanye isitshizi. Ngoko ke, ukuze kulawulwe ngokufanelekileyo ukubola kwentsimbi, ukwandisa ubomi benkonzo yesango lensimbi kunye nokuqinisekisa ukuthembeka kunye nokukhuseleka kokugcinwa kwamanzi kunye neeprojekthi ze-hydropower, ingxaki yexesha elide lokulwa ne-corrosion yesango lensimbi liye latsala ingqalelo enkulu.

Ubume bentsimbi yesango lesluice yesakhiwo sentsimbi kunye nezinto ezichaphazela umhlwa:

1.Imeko ye-Corrosion ye-steel structure sluice gate

Amanye amasango esinyithi esluice kunye nezakhiwo zentsimbi kwindawo yokugcina amanzi kunye neeprojekthi zombane wamanzi zintywiliselwa kumgangatho ohlukeneyo wamanzi (amanzi olwandle, amanzi amatsha, amanzi amdaka akwimizi-mveliso, njl.njl.) ixesha elide; Abanye bahlala kwindawo eyomileyo emanzi ngenxa yokutshintsha komgangatho wamanzi okanye ukuvulwa nokuvalwa kwesango; ezinye ziyakuchatshazelwa kukuhamba kwamanzi ngesantya esiphezulu kunye nokukhuhlana kwentlenga, inkunkuma edadayo kunye nomkhenkce; Inxalenye ekumphezulu wamanzi okanye ngaphezulu kwamanzi ikwachatshazelwa ngumoya ofumileyo wokuphuma kwamanzi abe ngumphunga kunye nenkungu etshizayo yamanzi; Izakhiwo ezisebenza kwiatmosfera zikwachatshazelwa kukukhanya kwelanga nomoya. Ngenxa yokuba indawo yokusebenza yesango le-hydraulic imbi kwaye kukho izinto ezininzi ezichaphazelayo, kuyimfuneko ukuhlalutya izinto zokubola.

2. Iimeko zomhlwa

(2) imeko yendawo yesakhiwo sensimbi: uburhalarhume, umonakalo womatshini, i-cavitation, iziphene ze-welding, izikhewu, njl.njl zinempembelelo enkulu kwi-corrosion.

(3) uxinzelelo kunye nokuguqulwa: ngakumbi uxinzelelo kunye ne-deformation, i-corrosion imbi kakhulu.

(4) umgangatho wamanzi: umthamo wetyuwa wamanzi acocekileyo uphantsi, yaye ukudleka kwesango kuyahluka ngokuxhomekeke kwimichiza kunye nongcoliseko; Amanzi olwandle anetyuwa eninzi kunye nokuhamba kakuhle. Amanzi olwandle aneeyoni ezininzi zekloridi, ezidla ngokutya intsimbi. Ukonakala kwesango lentsimbi kumanzi olwandle kubi kakhulu kunoko kumanzi amatsha.
