Endaweni yokusebenzela yakwaJinbin, abasebenzi balungisa insimbi engagqwalipenstock amasango. Isango le-penstock elinamathiselwe ngensimbi engagqwali lithandwa kakhulu emikhakheni yokonga amanzi kanye nokunikezwa kwamanzi kanye nokukhipha amanzi. Isizathu esiyinhloko sisezinhlelweni zazo ezingokwemvelo ezinobukhulu obuningi njengokubalulekile, ukwakheka, nokusebenzisa. Lezi zinzuzo ziyasekelana, zakha ukuncintisana okuphelele okudlula kude lokho kwamasango endabuko. (Abakhiqizi bePenstock)

Izakhiwo ezibonakalayo ziyisisekelo esiyisisekelo sokusungulwa kwayo. Umzimba oyinhloko wenziwe ngensimbi engagqwali engu-304 noma engu-316, engagcini nje ngokumelana ngokuqinile nama-asidi, ama-alkali nokugqwala, futhi engakwazi ukumelana nokuguguleka kwemithombo yezindaba egqwalayo, kodwa futhi ingakwazi ukuzivumelanisa nokucwiliswa isikhathi eside ezindaweni ezinomswakama nezinothe ngamanzi, igweme izinkinga zokugqwala nokuguga kwamasango ensimbi endabuko, nokuqinisa ukuqina kwesango lomthombo wensimbi, nokuqinisekisa ukusimama komthombo.

Isakhiwo esiyingqayizivele esifakwe odongeni sinikeza izinzuzo ezibalulekile zokufaka. Asikho isidingo sokuthulula isisekelo se-pier esindayo. Ingaxhunywa ngokuqondile odongeni noma odongeni lwe-pool ukuze kufakwe okugxilile, kube lula kakhulu inqubo yokwakha umphakathi kanye nokunciphisa izindleko zephrojekthi iyonke. Idizayini yayo yevolumu ehlangene ingakwazi ukuzivumelanisa nezimo ezicindezelayo zesikhala njengamanethiwekhi amapayipi amadala namakamelo amaphampu amancane, ukuxazulula ngokuphumelelayo inkinga yezidingo zesikhala sokufakwa okuphezulu kwamasango e-sluice evamile.

Inezinhlobonhlobo zezimo ezisebenzayo kanye nokuvumelana nezimo okuqinile. Noma ngabe uhlelo lwesibili lokuphakelwa kwamanzi lwezakhiwo zomphakathi, imigudu yokunisela yokukhiqiza yezolimo, noma amanethiwekhi okukhipha indle kanye nezindawo zokuhlanza indle emkhakheni wezimboni, zonke zingahlangabezana nezidingo ngokuvula nokuvala okuzinzile nokusebenza kwazo okuzinzile kanye nekhono lokulawula elivumelana nezimo, futhi azikhawulelwe uhla olujwayelekile lokushisa okuphakathi nendawo nokucindezela.

Ukunethezeka kokugcinwa nokuqina kwenza inzuzo yezomnotho ekabili. Ingaphezulu lensimbi engagqwali libushelelezi futhi liminyene, okwenza kube nzima ukuthi ukungcola nokungcola kubambelele. Ukugcinwa kwansuku zonke kudinga kuphela ukuhlanzwa okulula futhi akudingi ukukhishwa njalo kokugqwala noma ukudweba. Izindleko zonyaka zokulungisa ziphansi kakhulu. Ngesikhathi esifanayo, i-stainless steel penstock valve inamandla amakhulu esakhiwo, ukumelana nokugqokwa okuqinile, kanye nempilo yesevisi evamile edlula kude le yamasango endabuko, inciphisa imvamisa yokushintshwa kanye nokutshalwa kwezimali okulandelayo.
