Izintambo zangaphansi kolwandle zidlala indima ebalulekile ekuxhumaneni komhlaba wonke, zithwala idatha eningi olwandle. Ukukhetha izinto ezifanele zalezi zintambo kubalulekile ukuqinisekisa ukuqina kwazo, ukusebenza kwazo, kanye nokuthembeka kwazo ezindaweni ezingaphansi kwamanzi eziyinselele. Kulesi sihloko, sizohlola izinselele ezihilelekile ekukhetheni izinto zezintambo zangaphansi kolwandle futhi sixoxe ngezixazululo ezingasiza ekwenzeni izinqumo ezinolwazi.
Ukumelana Nokugqwala:
Enye yezinselele eziyinhloko ekwakhiweni kwekhebula langaphansi kolwandle ukugqwala. Izintambo zivezwa emanzini olwandle, okungabangela umonakalo omkhulu wokugqwala ngokuhamba kwesikhathi. Ukukhetha izinto ezinokumelana nokugqwala okuhle kubalulekile ukuze ikhebula lihlale isikhathi eside. Izixazululo ezifana nokusebenzisa ama-alloy amelana nokugqwala njengensimbi engagqwali noma ukusebenzisa izembozo ezikhethekile zinganikeza isivikelo esisebenzayo ekugqwaleni.
Amandla Okusebenza:
Izintambo zangaphansi kolwandle zidinga ukumelana nokucindezela okukhulu kanye nokucindezeleka kwemishini ngenxa yemisinga yolwandle, amagagasi, kanye nesisindo samanzi. Ukukhetha Izinto Zokusebenzisa Izintambo Zangaphansi Kolwandle ezinamandla aphezulu kwemishini kubalulekile ukuqinisekisa ukuthi izintambo zingakwazi ukumelana nalezi mandla ngaphandle kokubeka engcupheni ubuqotho bazo. Izinto ezinamandla aphezulu njengezintambo ze-aramid kanye nama-polymers aqiniswe nge-carbon fiber (CFRP) zivame ukusetshenziselwa ukuthuthukisa izakhiwo zemishini zezintambo zangaphansi kolwandle.
Ukuvimba Amanzi Nokumboza:
Ukugcina ukuvikela okufanele kanye nezakhiwo zokuvimba amanzi kubalulekile ukuvimbela ukungena kwamanzi nokuvikela izingxenye zangaphakathi zekhebula. I-Polyethylene, i-polypropylene, kanye ne-cross-linked polyethylene (XLPE) zivame ukusetshenziselwa ukuvikela nokuvimbela amanzi ezintanjeni zamanzi. Lezi zinto zinikeza izakhiwo ezinhle kakhulu zokuvikela ugesi futhi zingamelana nokungena kwamanzi, ziqinisekise ukusebenza kahle kwekhebula kanye nokuphila isikhathi eside.
Ukuguquguquka kanye ne-Bend Radius:
Izintambo zangaphansi kolwandle zivame ukudinga ukuguquguquka futhi zikwazi ukumelana nokugoba okuphindaphindiwe ngaphandle kokuphazamisa ukusebenza kwazo. Izinto zokwakha Izintambo zangaphansi kolwandle ezinokuguquguquka okuphezulu kanye nokuqina okuphansi kokugoba, njengezinhlobo ezithile ze-polyurethane kanye ne-elastomers, zivame ukusetshenziswa ukuqinisekisa ukuthi izintambo zingafakwa futhi zigcinwe ezimweni ezahlukene zangaphansi kolwandle ngenkathi zigcina ubuqotho bazo kagesi kanye nobemishini.
Ukuzinza Kokushisa:
Izintambo zangaphansi kolwandle zingase zithole ukushintshashintsha okukhulu kwezinga lokushisa ezindaweni ezingaphansi kwamanzi. Kubalulekile ukukhetha Izinto Zokusebenzisa Izintambo Zangaphansi Kolwandle ezinokuqina okuhle kokushisa ukuqinisekisa ukuthi izintambo zingakwazi ukumelana nalezi zinguquko zokushisa ngaphandle kokuthinta ukusebenza kwazo. Izinto ze-thermoplastic ezifana ne-polyethylene ne-polypropylene zinikeza ukuzinza okuhle kokushisa, okwenza kube ukukhetha okufanele kwezingqimba zokushisa kanye nezendlalelo zokubopha.
Isiphetho:
Ukukhetha izinto ezifanele zezintambo zasemanzini kuyinqubo ebalulekile ehilela ukucabangela izinselele ezithile eziphathelene nezimo ezingaphansi kwamanzi. Ngokubhekana nezici ezifana nokumelana nokugqwala, amandla omshini, ukuvimba amanzi, ukuguquguquka, kanye nokuqina kokushisa, abakhiqizi bezintambo kanye nabaqhubi bangaqinisekisa ukusebenza kahle kanye nobude bezintambo zasemanzini. Ukuqonda lezi zinselele nokusebenzisa izixazululo zezinto ezifanele kubalulekile kumanethiwekhi okuxhumana omhlaba wonke athembekile futhi asebenzayo.
