Isikulufu sokuvala esivamile siyisakhiwo sesigaba, ngokuvamile isikulufu sezinyo lonke, esishiselwe phakathi kweshidi lokuvala noma simbozwe ngendandatho yokuvala yokunwebeka, ukuvimbela amanzi ukuthi angadluli odongeni olungaphansi.
Ukuze kongiwe insimbi, u-Hebei Dashan uvele uhlobo olusha lwesikulufu sokuvala, kusukela engxenyeni yesakhiwo ukuya engxenyeni yesakhiwo, eyaziwa nangokuthi izigaba ezintathu zesikulufu sokudonsa.
Isikulufu sokuvala ukudonsa esinezigaba ezintathu sakhiwe ngesikulufu esimaphakathi esixhunywe nezikulufu ezimbili ezilinganayo ekugcineni, isikulufu esimaphakathi sinikezwa ishidi lokumisa amanzi nezitobhi ezimbili, futhi isikulufu sokugcina sihlinzekwa ngemicu yokubopha namantongomane okubopha.Iziphetho ezimbili zesikulufu esimaphakathi zihlinzekwa ngoxhumano lwentambo yangaphandle, futhi ingxenye eyodwa yesikulufu sokugcina inikezwa ngoxhumano lwentambo yangaphakathi kanye noxhumano lwesikulufu esimaphakathi sokumatanisa kwentambo yangaphandle.Ukuxhumana phakathi kwesikulufu esiphakathi nesikulufu sokugcina simbozwe ngephedi le-tubular, ingxenye emaphakathi yephedi iyindandatho yokulinda, ubuso bokuphela kwephedi ye-tubular buhlelwe eduze kwesiyingi somjikelezo wekholomu ye-axial, futhi kukhona. igebe phakathi kwamakholomu.Ubuso bokuphela kwephedi buhlinzekwa ngembobo yokonga impahla.Ngesikulufu esiphakathi nendawo nesiphetho sokuhlanganiswa inhlanganisela yesikulufu sokumisa amanzi, nesikulufu esivamile sokumisa amanzi esisetshenziselwa ukwakha isikhunta sokubunjwa sikakhonkolo, asidingi ukushintsha inqubo yokwakha ekhona, kulula ukukhuthaza ukusetshenziswa.Ngemva kokuthelwa kukakhonkolo nesifanekiso sikhishiwe, isikulufu sokugcina singakhishwa kusikulufu esimaphakathi esishunyekwe odongeni ukuze sigaywe kabusha, futhi isikulufu sokuphela esitholiwe singasetshenziswa kabusha ngesikulufu esisha esiphakathi.
Ipuleti lensimbi yokumisa amanzi.Ebhokisini lesisekelo noma elingaphansi, ipuleti elingaphansi kanye nephaneli yodonga, ukhonkolo wophahla uthululelwa ngokuhlukile futhi ugxivizwe.Lapho ukhonkolo wephaneli odongeni uthululelwa futhi ngokuzayo, kukhona ukuhlanganiswa okubandayo kokwakhiwa.Lapho indawo yokuhlangana ingaphansi kwezinga lamanzi angaphansi komhlaba, kulula ukukhiqiza ukugeleza kwamanzi.Ngale ndlela, kuyadingeka ukwenza ukwelashwa kwezobuchwepheshe kulo mthungo.Kunezindlela eziningi zokwelapha, phakathi kwazo indlela ethandwa kakhulu ukusetha ipuleti yensimbi yokufaka uphawu
Ipuleti elijwayelekile lensimbi yokumisa amanzi ukusebenzisa ipuleti eligoqiwe elibandayo njengesisekelo sezinto, ngoba ubukhulu bepuleti elibandayo bungaba umfaniswano, ukushuba kwepuleti elishisayo alikwazi ukufinyelela i-uniform degree, ukushuba ngokuvamile kungu-2 mm noma 3 mm, ubude ngokuvamile bucutshungulwa bube ngamamitha angu-3 ubude noma amamitha angu-6 ubude, ngokuvamile amamitha amathathu ukuthutha okuhle.
