Kwethulwa izindlela ezintathu ezijwayelekile zokubeka izintambo zangaphandle, okuyilezi: ukubekwa kwamapayipi, ukungcwatshwa okuqondile kanye nokubekwa phezulu.Okulandelayo kuzochaza izindlela zokubeka kanye nezidingo zalezi zindlela ezintathu zokubeka ngokuningiliziwe.
Ukufakwa kwepayipi/udoti
Ukufakwa kwamapayipi kuyindlela esetshenziswa kakhulu kumaphrojekthi wokubeka amakhebula optical, futhi ukubekwa kwawo kufanele kuhlangabezane nezidingo ezilandelayo:
1. Ngaphambi kokubeka ikhebula le-optical, i-sub-hole kufanele ifakwe emgodini we-tube.Ikhebula le-optical kufanele lihlale libekwe ku-sub-tube yombala ofanayo.I-sub-tube orifice engasetshenziswanga kufanele ivikelwe ngepulaki.
2. Uma kucatshangelwa ukuthi inqubo yokubeka iwukusebenza okwenziwa ngesandla, ukuze kuncishiswe ukulahleka kwamalunga ekhebula optical, umkhiqizi wekhebula optical ophayiphi kufanele asebenzise yonke indawo yokubeka ipuleti.
3. Ngesikhathi senqubo yokubeka, amandla okudonsa ngesikhathi sokubeka kufanele ancishiswe.Yonke ikhebula le-optical kufanele libekwe kusukela phakathi kuya ezinhlangothini zombili, futhi abasebenzi kufanele bahlelwe emgodini ngamunye ukuze basize ekudonseni okuphakathi.
4. Isikhundla sembobo yekhebula le-optical kufanele sihlangabezane nezidingo zemidwebo yokuklama, futhi imbobo yepayipi kufanele ihlanzwe ngaphambi kokubeka intambo yepayipi ye-optical.Ishubhu ye-orifice engaphansi kwembobo kufanele iveze ubude obusele obungaba ngu-15cm wembobo yeshubhu emgodini wesandla.
5. Isixhumi esibonakalayo phakathi kwepayipi elingaphakathi lembobo yesandla kanye nepayipi le-plastic textile mesh ligoqwa ngetheyiphu ye-PVC ukugwema ukungena kwenhlabathi.
6. Uma ikhebula le-optical lifakwe emgodini womuntu (wesandla), uma kukhona ipuleti elisekela emgodini wesandla, ikhebula le-optical ligxiliwe epuleti elisekelayo.Uma lingekho ipuleti elisekelayo embotsheni yesandla, ikhebula le-optical kufanele limiswe kubhawodi yokunweba.Umlomo we-hook uyadingeka ukuze ube phansi.
7. Intambo yokubona akufanele igotshwe phakathi kuka-15cm wembobo yokuphuma.
8. Izimpawu zepulasitiki zisetshenziswa embotsheni ngayinye yesandla nakukhebuli yokubona kanye nohlaka lwe-ODF lwegumbi lekhompyutha ukukhombisa umehluko.
9. Imigudu yekhebula yokubona kanye nemigudu kagesi kumele ihlukaniswe okungenani ngosimende owugqinsi ongu-8cm noma ungqimba lomhlabathi ohlangene owugqinsi oluwu-30cm.
Ukungcwatshwa Okuqondile
Uma ingekho imibandela yokusetshenziswa phezulu ngaphansi kwezimo zokubeka futhi nebanga lokubeka lide, ukungcwatshwa okuqondile kuvamile kusetshenziswa, futhi ukungcwatshwa okuqondile kufanele kuhlangabezane nalezi zidingo ezilandelayo:
1. Gwema izindawo ezine-asidi eqinile kanye nokugqwala kwe-alkali noma ukugqwala okukhulu kwamakhemikhali;uma zingekho izinyathelo zokuvikela ezihambisanayo, gwema izindawo zokulimala komhlwa kanye nezindawo ezithintwa imithombo yokushisa noma izindawo ezilinyazwa kalula amandla angaphandle.
2. Ikhebula le-optical kufanele libekwe emseleni, futhi indawo ezungezile yekhebula le-optical kufanele imbozwe ngenhlabathi ethambile noma ungqimba lwesihlabathi olunogqinsi olungekho ngaphansi kuka-100mm.
3. Kubo bonke ubude bekhebula le-optical, ipuleti elivikelayo elinobubanzi obungekho ngaphansi kuka-50mm ezinhlangothini zombili zekhebula le-optical kufanele limbozwe, futhi ipuleti yokuzivikela kufanele yenziwe ngokhonkolo.
4. Indawo yokubeka isezindaweni lapho kumbiwa khona njalo, njengemigwaqo engenela emadolobheni, futhi amabhande ezimpawu adonsa amehlo angabekwa ebhodini lokuvikela.
5. Endaweni yokubeka endaweni engaphansi kwedolobha noma ebhandeni elivulekile, endaweni yomugqa oqondile ongaba ngu-100mm eduze kwendlela yekhebula le-optical, ezindaweni eziphendukayo noma ezihlangene, izimpawu zokuma noma izigxobo kufanele zimiswe.
6. Uma ubeka ezindaweni zenhlabathi ezingaqandisiwe, ukujula komgodla wekhebula esisekelweni sesakhiwo esingaphansi komhlaba akufanele kube ngaphansi kuka-0.3m, futhi ukujula komgodla wekhebula phansi akumele kube ngaphansi kuka-0.7m;lapho itholakala endleleni yomgwaqo noma inhlabathi etshaliwe, kufanele ijule kahle, futhi akufanele ibe ngaphansi kuka-1m.
7. Uma ubeka endaweni yenhlabathi efriziwe, kufanele ingcwatshwe ngaphansi kwesendlalelo senhlabathi efriziwe.Uma ingakwazi ukungcwatshwa ngokujulile, ingangcwatshwa emhlabathini owomile oqandisiwe noma umhlabathi ogcwele amanzi ngokugeleza okuhle komhlabathi, nezinye izinyathelo zokuvimbela ukulimala kwekhebula le-optical nazo zingathathwa..
8. Uma ulayini wekhebula obonayo ogqitshwe ngokuqondile unqamula ujantshi wesitimela, umgwaqo onguthelawayeka noma umgwaqo, ipayipi lokuvikela kufanele ligqokwe, futhi ububanzi bokuvikela kufanele budlule umbhede womgwaqo, izinhlangothi zombili zomgwaqo ogandayiwe kanye nohlangothi lomsele wokudonsa amanzi ngaphezu kwalokho. 0.5m.
9. Uma ikhebula le-optical eligqitshwe ngokuqondile lifakwa esakhiweni, ipayipi lokuvikela kufanele libekwe emgodini odlulayo, futhi umlomo wepayipi kufanele uvinjwe ukuvinjelwa kwamanzi.
10. Ibanga elicacile phakathi kwejoyinti lentambo yokubona egqitshwe ngokuqondile kanye nekhebula lokubona eliseduze akufanele libe ngaphansi kuka-0.25m;izikhundla ezihlangene zezintambo ezibonakalayo ezihambisanayo kufanele zinyakaze ukusuka komunye nomunye, futhi ibanga elicacile akufanele libe ngaphansi kuka-0.5m;indawo ehlangene endaweni yemithambeka kufanele ibe evundlile;kumasekhethi abalulekile Kunconywa ukuthi ushiye indlela eyisipele yokubeka ikhebula le-optical esigabeni sendawo kusukela cishe ku-1000mm ezinhlangothini zombili ze-optical cable joint.
I-Overhead/Aerial Laying
Ukwendlaleka ngaphezulu kungaba khona phakathi kwezakhiwo nezakhiwo, phakathi kwezakhiwo nezigxobo zezinsiza, naphakathi kwezigxobo zosizo nezigxobo.Ukusebenza kwangempela kuncike esimweni ngaleso sikhathi.Uma kunezigxobo zezinsiza phakathi kwezakhiwo, izintambo zocingo zingamiswa phakathi kwezakhiwo nezigxobo zezinsiza, futhi izintambo zokukhanya ziboshwe ezintanjeni zocingo;uma zingekho izigxobo ezisetshenziswayo phakathi kwezakhiwo, kodwa ibanga phakathi kwezakhiwo ezimbili licishe libe ngama-50m, izintambo ze-Optical nazo zingamiswa ngokuqondile phakathi kwezakhiwo ngezintambo zensimbi.Izidingo zokubeka zimi kanje:
1. Uma ubeka ikhebula le-optical endaweni eyisicaba ngendlela ye-overhead, sebenzisa ihuku ukulengisa;beka intambo yokubona entabeni noma emthambekeni owumqansa, futhi usebenzise indlela yokubopha ukuze ubeke intambo yokubona.Isixhumi sekhebula le-optical kufanele sikhethe indawo yesigxobo esiqondile okulula ukuyinakekela, futhi ikhebula le-optical eligodliwe kufanele limiswe esigxotsheni ngobakaki ogodliwe.
2. Intambo yokubona yomgwaqo wepali ongaphezulu iyadingeka ukwenza i-telescopic emise okuka-U njalo ngamabhulokhi ama-3 kuya ku-5, futhi cishe i-15m igcinelwe i-1km ngayinye.
3. Intambo yokukhanya engaphezulu (odongeni) ivikelwe ngepayipi lensimbi, futhi umlomo wombhobho kufanele uvalwe ngodaka olungashi.
4. Izintambo ezibona phezulu kufanele zilengiswe ngezimpawu eziyisixwayiso zekhebula njalo emabhulokhini angu-4 nxazonke nasezigabeni ezikhethekile njengokuwela imigwaqo, imifula, namabhuloho.
5. Ishubhu yokuvikela i-trident kufanele yengezwe ezimpambanweni zomugqa wokulengiswa ongenalutho kanye nentambo yamandla, futhi ukunwetshwa komkhawulo ngamunye akufanele kube ngaphansi kwe-1m.
6. Intambo yesigxobo esiseduze nomgwaqo kufanele isongwe ngenduku ekhipha ukukhanya, ubude obungu-2m.
7. Ukuze kuvinjwe amandla omoya ocingweni olumisiwe ekulimazeni abantu, intambo yesigxobo ngayinye kufanele ixhunywe ngogesi ocingweni olulengayo, futhi indawo ngayinye yocingo oludonsayo kufanele ifakwe ngohlobo lwentambo edonsayo yocingo lwaphansi.
8. Ikhebula elibona phezulu livamise ukuba ngamamitha amathathu ukusuka phansi.Uma ungena esakhiweni, kufanele udlule emkhonweni ovikelayo wensimbi omise okwe-U odongeni olungaphandle lwesakhiwo, bese welula ubheke phansi noma phezulu.Imbobo yokungena kwekhebula le-optical ngokuvamile ingu-5cm.
