Ubunzulu bokungcwatywa kwentambo yokukhanya engcwatywe ngokuthe ngqo buya kuhlangabezana namalungiselelo afanelekileyo eemfuno zoyilo lobunjineli bonxibelelwano lwentambo yentambo yonxibelelwano, kwaye ubunzulu obuthile bokungcwaba buya kuhlangabezana neemfuno kwitheyibhile engezantsi.Intambo yokukhanya kufuneka ibe mcaba ngokwendalo phantsi komsele, kwaye kungabikho xinzelelo kunye nesithuba.Ububanzi bomsele ogrunjwe ngokuzenzela kufuneka bube yi-400mm.
Kwangaxeshanye, ukubekwa kweentambo zamehlo ezingcwatyiweyo kufuneka zifezekise ezi mfuno zilandelayo:
1. I-radius ye-curvature ye-cable optical engcwatywe ngokuthe ngqo kufuneka ibe ngaphezu kwamaxesha angama-20 ububanzi obungaphandle bekhebula le-optical cable.
2. Iintambo ze-Optical zinokufakwa kumsele ofanayo kunye nezinye iintambo zonxibelelwano zonxibelelwano.Xa ubeka emseleni omnye, kufuneka bahlelwe ngokuhambelanayo ngaphandle kokugqithisa okanye ukuwela.Umgama ocacileyo ohambelanayo phakathi kweentambo kufuneka ube ≥ 100mm.
Ngqo wangcwatywa intambo yamehlo ebeka parameter table.jpg
Itheyibhile yomgama omncinane ocacileyo phakathi kwemigca yonxibelelwano engcwatywe ngqo kunye nezinye izibonelelo
3. Xa intambo ye-optical engcwatywe ngokuthe ngqo ihambelana okanye iwela kunye nezinye izibonelelo, umgama phakathi kwabo awuyi kuba ngaphantsi kwezibonelelo kwitheyibhile engentla.
4. Xa intambo ye-optical ibekwe kwiindawo ezinokuguquguquka okukhulu komhlaba (ezifana neentaba, i-terraces, imisele eyomileyo, njl. njl.), kufuneka ihlangabezane neemfuno ezichaziweyo zokungcwaba ubunzulu kunye ne-radius of curvature.
5. Imilo "S" mayisetyenziselwe ukwandlalela kumathambeka anethambeka elikhulu kuno-20° kunye nobude bethambeka eligreyidi.
phezu kwe 30m.Xa umsele wentambo ye-optical kwithambeka kunokwenzeka ukuba uhlanjwe ngamanzi, amanyathelo afana nokuqiniswa kokuvalwa okanye ukuguqulwa kufuneka kuthathwe.Xa ubeka kwi-slope ende kunye ne-slope enkulu kune-30 °, kuyacetyiswa ukuba kusetyenziswe i-cable ekhethekileyo ye-optical cable (ngokuqhelekileyo intambo yensimbi ye-armored optical cable).
6. Umlomo wentambo ye-optical engcwatywe ngokuthe ngqo edlula kwi-tube yokukhusela kufuneka ivalwe ngokuqinileyo
7. I-tube yokukhusela kufuneka ifakwe apho i-cable optical engcwatywe ngokuthe ngqo ingena kwindoda (isandla) umgodi.Umaleko wokukhusela isikrweqe sentambo yokukhanya kufuneka ufikelele malunga ne-100mm ukusuka kwindawo yenkxaso yangaphambili kumngxuma.
8. Iimpawu ezahlukeneyo zeentambo ze-optical ezingcwatywe ngokuthe ngqo kufuneka zifakwe ngokweemfuno zoyilo.
9. Amanyathelo okhuseleko angcwatywa ngokuthe ngqo
iintambo ezithe ngqo ezidlulayo
imiqobo erhabaxa kufuneka ihlangabezane neemfuno zoyilo.
Ukuzaliswa ngasemva kufuneka kuhlangabezane noku kulandelayo
iimfuno:
1. Gcwalisa umhlaba omhle
kuqala, ngoko umhlaba oqhelekileyo, kwaye musa ukonakalisa iintambo zamehlo kunye neminye imibhobho emseleni.
2. Emva kokugcwalisa i-300mm yomhlaba ocolekileyo kwiintambo ze-optical ezingcwatywe kwiindawo ezisezidolophini okanye ezidolophini, zigubungele ngezitena ezibomvu zokukhusela.Ngalo lonke ixesha malunga ne-300mm yomhlaba osemva kufuneka ugayiwe kube kanye, kwaye umhlaba oseleyo kufuneka ucocwe ngexesha.
3 Umsele wentambo ye-optical emva kokuba umhlaba uhlanganisiwe kufuneka uhlanjululwe kunye nomgangatho wendlela kwindlela okanye kwi-sidewalk yezitena, kwaye umhlaba ongasemva akufanele ube naluphi na ukudakumba phambi kokulungiswa kwendawo yendlela;indlela yomhlaba inokuba ngama-50-100mm ukuphakama kunomgangatho wendlela, kwaye umhlaba ongasedolophini unokuba malunga ne-150mm ukuphakama.
Xa kufuneka intambo ye-micro-groove optical kumphezulu wendlela, i-cable groove kufuneka inqunyulwe ngokuthe tye, kwaye ububanzi be-groove kufuneka bugqitywe ngokwe-diameter yangaphandle yentambo ye-optical ebekwe, ngokubanzi ngaphantsi kwe-20mm;Ubunzulu sh
inokuba ngaphantsi kwe-2/3 yobunzima bomphezulu wendlela;i-bottom of the groove cable kufuneka ibe tyaba, ngaphandle kwee-sills ezinzima (amanyathelo), kwaye akufanele kubekho i-debris efana negrabile;i-angle yekona ye-groove kufuneka ihlangabezane neemfuno ze-radius ye-curvature emva kokuba intambo ibekwe.Kwangaxeshanye, ezi mfuno zilandelayo nazo kufuneka zilandelwe:
1. Ngaphambi kokubeka intambo ye-optical, kuyacetyiswa ukuba ubeke isanti ecocekileyo eyi-10mm phantsi komsele okanye ubeke umcu we-foam kunye nobubanzi obufana nobubanzi bomsele njenge-buffer.
2. Emva kokuba intambo ye-optical ifakwe kwi-groove, imathiriyeli yokukhusela i-buffer kufuneka ibekwe phezulu kwentambo ye-optical ngokweempawu ezahlukeneyo zezinto zokubuyisela i-pavement.
3. Ukubuyiselwa kwendlela yabahambi ngeenyawo kufuneka kuhlangabezane neemfuno zogunyaziwe wendlela;kunye nesakhiwo sepavumente emva kokubuyiselwa kufuneka sihlangabezane nemfuneko yomsebenzi wenkonzoizinto zecandelo lendlela elihambelanayo.
