- Isihlabathi: Nakuba idonsa ngokushesha, isihlabathi sishintsha kalula, okungenzeka siveze izintambo.
- Loam: Ingxube elinganiselayo yesihlabathi, udaka, nobumba, i-loam inikeza ukuzinza futhi ngokuvamile ilungele ukungcwatshwa kwekhebula.
- Umhlabathi Wamadwala: Kunzima ukufaka umsele, inhlabathi enamadwala ingase ilimaze izintambo ngesikhathi sokufakwa.
- Silt: Okuhle nokungagcini amanzi, izingozi ze-silt eziguquguqukayo kanye nokugeza.
Ukuze kuncishiswe lezi zinselele, amaqembu avame ukusebenzisa imisele engangeni manzi futhi engeza amatshe noma isihlabathi ukuze akhiphe amanzi enhlabathini engazinzile. Ukuyisa izintambo kude nezindawo ezithandwa yizikhukhula kunciphisa futhi izingozi.
Ithiphu: Ukwenza ukuhlolwa kwenhlabathi ngaphambi kokufaka kuqinisekisa ukukhethwa kwezinhlobo zekhebula ezifanele kanye nezinyathelo zokuzivikela.
Ukubhekana Nezinselele Zetafula Lamanzi
Amathebula aphezulu amanzi adala ubungozi obukhulu ezintamboni ze-fiber optic ezigqitshiwe, okuhlanganisa ukungena kwamanzi kanye nokuwohloka kwesignali. Onjiniyela kufanele bahlole izimo ze-hydrological ukuze bakhe izixazululo ezisebenzayo.
Amasu ahlanganisa:
- Ukufaka izintambo ezinezendlalelo ezithuthukisiwe zokuvimba amanzi.
- Ukusebenzisa amatshe noma isihlabathi ukuthuthukisa ukugeleza kwamanzi eduze kwekhebula.
- Ukugwema izindlela eziphansi ezivame ukuba nezikhukhula.
Ezindaweni ezinamatafula amanzi ashintshashintshayo, imigudu yokuvikela inikeza izivikelo ezengeziwe. Lezi zinyathelo ziqinisekisa ukuthi izintambo zihlala zisebenza naphezu kwezinselelo zemvelo.
Ukunciphisa Umthelela Wezemvelo Nasemadolobheni
Ukufakwa kwekhebula ezindaweni zasemadolobheni kufanele kulinganise ukuthuthukiswa kwengqalasizinda nokulondolozwa kwemvelo. Amaqembu abeka phambili izinqubo ezizinzile ukuzenciphisa ukuphazamiseka.
- Izintambo zomzila ukuze kugwenywe izindawo ezingamaxhaphozi kanye nemvelo ebucayi.
- Ukumba ngesandla eduze kwezimpande zesihlahla ukuvimbela umonakalo.
- Ukubuyisela umhlaba ngemva kokufakwa ukuze kugcinwe ibhalansi yemvelo.
Imibiko yokuhlela amadolobha ivame ukugcizelela ukubaluleka kokunciphisa ukuphazamiseka okuhlobene nokwakhiwa. Ngokunamathela kulezi zinqubo, amadolobha anganweba amanethiwekhi awo e-fiber optic kuyilapho elondoloza indawo yawo yemvelo kanye nedolobha.
Qaphela: Ukufaka izindlela ezilungele imvelo akugcini nje ngokuvikela imvelo kodwa futhi kuthuthukisa ukusekelwa komphakathi kumaphrojekthi wengqalasizinda.
Ukuhlola Nokuqinisekisa Ikhwalithi
Amaphrothokholi okuhlola okufakwa ngaphambilini

Ukuqinisekisa Ukuthobelana Namazinga Omkhakha
Ukunamathela ezindinganisweni zomkhakha kuqinisekisa ikhwalithi nokuthembeka kokufakwa kwe-fiber optic. II-IEC 61300-3-35 ejwayelekileidlala indima ebalulekile ekugcineni inhlanzeko nokusebenza ekuxhumekeni kwe-fiber optic. Ihlinzeka ngemibandela yokugreda eyinhloso yokuhlolwa kwenhlanzeko, isuse ukwahlulela okuqondile. Izidingo zesitifiketi ziyahlukahluka kuye ngohlobo lwesixhumi, usayizi wefayibha, nezigaba zokukhubazeka, njengokuklwebheka nokungcola.
Ithiphu: Ukulandela la mazinga akuqinisekisi ukuthobela kuphela kodwa futhi kuthuthukisa ukuqina nokusebenza kahle kwamanethiwekhi e-fiber optic.
Ngokusebenzisa ukuhlola okuqinile nokunamathela ezilinganisweni ezimisiwe, amaphrojekthi wengqalasizinda yedolobha angafinyelela amanethiwekhi okuxhumana aqinile nathembekile.
Ukufakwa nokugcinwa okuyimpumelelo kwekhebula le-fiber optic yokungcwaba kuncike ekuhleleni okucophelelayo, ekwenzeni okunembayo, nasekunakekeleni okuqhubekayo. Izinyathelo ezibalulekile zifaka ukuhlela umzila, ukuhlolwa kwenhlabathi, kanye nokubambelela ezindinganisweni zemboni ngesikhathi sokugenca, ukufakwa kwekhebula, nokugcwalisa ngemuva. Ukuhlolwa okuvamile kanye nezinyathelo zokuvikela eziqinile zithuthukisa ukwethembeka kwenethiwekhi.
Le ndlela yokufaka inikeza izinzuzo ezingenakuqhathaniswa zengqalasizinda yasemadolobheni. Ukuqina kwayo, ukusebenza kahle kwezindleko, kanye nekhono lokusekela ukudluliswa kwedatha ngesivinini esikhulu kuyenza ibaluleke kakhulu emadolobheni anamuhla. Ngokufakwa okufanele, lezi zintambo zingasebenzisa amanethiwekhi asemadolobheni amashumi eminyaka, njengoba kuqinisekiswa izici zawo zokwakha eziqinile kanyeimpilo ende yesevisi.
Ukwamukela izinqubo ezihamba phambili kuqinisekisa ukwethembeka kwesikhathi eside futhi kunciphisa ukuphazamiseka. U-Dowell, umholi othenjwayo ezisombululweni ze-fiber optic, unikeza isiqondiso sochwepheshe ukuze kusetshenziswe kalula. Xhumana no-Eric, Umphathi Womnyango Wezohwebo Zangaphandle, ukuze uthole izixazululo eziklanyelwe ezihlangabezana nezidingo zakho zengqalasizinda yedolobha.
