Izintambo zokungenza zasolwandle zidlala indima ebalulekile ekuxhumaneni komhlaba wonke, ziphethe inani elikhulu lemininingwane kuwo wonke ama-Oceans. Ukukhetha izinto ezifanele zalezi zintambo kubalulekile ukuze kuqinisekiswe ukuqina kwazo, ukusebenza, kanye nokwethenjwa ekunciphiseni kwezindawo ezingaphansi kwamanzi. Kulesi sihloko, sizohlola izinselelo ezibandakanyeka ekukhetheni izinto zezintambo zangaphansi komhlaba bese sixoxa ngezixazululo ezingasiza ekwenzeni izinqumo ezinolwazi.
Ukumelana nokugqwala:
Enye yezinselelo eziyinhloko ukwakheka kwekhebula ngaphansi komhlaba. Izintambo zivezwa emanzini olwandle, ezingadala ukulimala okukhulu kokugqwala ngokuhamba kwesikhathi. Ukukhetha izinto zokwakha ezinokumelana kahle kokugqwala kubalulekile empilweni ye-Cable ende. Izixazululo ezinjengokusebenzisa ama-alloys alwa nokugqwala njengensimbi engenasici noma asebenzisa izigqoko ezikhethekile anganikeza ukuvikela okusebenzayo ekubhujisweni.
Amandla okwenziwa ngomshini:
Izintambo zokungaphansi zabantu zidinga ukumelana nengcindezi enkulu nokucindezelwa kwemishini ngenxa yemisinga yolwandle, amagagasi, kanye nesisindo samanzi. Ukukhetha izinto zezintambo zamakhekhe angaphansi komhlaba ezinamandla amakhulu wemishini kubalulekile ukuqinisekisa ukuthi izintambo zingamelana nalawo mandla ngaphandle kokuyekethisa ubuqotho babo. Izinto zokuqinisa eziphakeme eziphakeme njengezicucu ze-aramid kanye ne-polymers eqiniswe yi-carbon
Ukuvinjwa kwamanzi nokufakelwa:
Ukugcina ukufakwa okufanele kanye nezakhiwo ezivimba amanzi kubalulekile ukuvikela ukungena kwamanzi nokuvikela izingxenye zangaphakathi zentambo. I-Polyethylene, i-polypropylene, kanye ne-polyethylene exhumene ne-cross Lezi zinto zokwenziwa zinikeza izakhiwo ezinhle kakhulu zokufakwa kukagesi futhi zingamelana nokungena kwamanzi, ziqinisekisa ukusebenza kahle kwentambo kanye nokuphila isikhathi eside.
Ukuvumelana nezimo kanye nokugoba irediyo:
Izintambo zokungaphansi komhlaba zivame ukudinga ukuguquguquka futhi zikwazi ukubekezelela ukugoba okuphindaphindiwe ngaphandle kokuyekethisa ukusebenza kwawo. Izinto ezisetshenziswayo zamakhebule angaphansi komhlaba ngokuguquguquka okuphezulu kanye nokugoba okuphansi, njengezinhlobo ezithile ze-polyurethane nama-lastomers, zivame ukusetshenziswa ukuqiniseka ukuthi amakhekhe angafakwa futhi agcinwe ngokwethembeka kwawo kagesi nokwenza imisebenzi.
Ukuqina okushisayo:
Izintambo zangaphansi zingathola ukuhlukahluka okuphansi kwezinga lokushisa ezindaweni ezingaphansi kwamanzi. Kubalulekile ukuthi ukhethe izinto zezintambo zezintambo zomkhumbi ngokuqina okuhle kakhulu ukuze uqinisekise ukuthi izintambo zingamelana nalezi zinguquko zokushisa ngaphandle kokuthinta ukusebenza kwazo. Izinto ze-thermoplastic ezifana ne-polyethylene ne-polypropylene zinikeza ukuzinza okuhle okushisayo, okwenza ukuba babe nezinketho ezifanele zokufakelwa kanye nezendlalelo zokushaya.
Isiphetho:
Ukukhetha izinto ezifanele zezintambo zangaphansi komhlaba kuyinqubo ebalulekile ehilela ukucabanga ngezinselelo ezithile ngezimo ezingaphansi kwamanzi. Ngokubhekana nezinto ezifana nokumelana nokugqwala, amandla emishini, ukuvinjwa kwamanzi, ukuguquguquka, kanye nokuqina okushisayo, abakhiqizi bekhebula nabasebenza ngokusebenza kwamakhebuli angaphansi komhlaba. Ukuqonda lezi zinselelo kanye nokusebenzisa izixazululo ezifanele ezibonakalayo kubalulekile kumanethiwekhi okuxhumana athembekile nawokusebenza kahle.
