Umkhawulo owodwa wekhebula le-optical ugxilwe ogwini, futhi umkhumbi uhamba kancane uye olwandle oluvulekile.Ngenkathi ucwilisa intambo yokubona noma ikhebula olwandle,

i-excavator eshona phansi yolwandle isetshenziselwa ukubeka.

Umkhumbi (umkhumbi wekhebula), i-submarine excavator

1. Umkhumbi wekhebula uyadingeka ukuze kumiswe izintambo ze-trans ocean optical.Lapho ubeka, umqulu omkhulu wekhebula le-optical uzofakwa emkhunjini.Okwamanje,

umkhumbi osezingeni eliphezulu kakhulu obeka ikhebula lokukhanya ungathwala amakhilomitha angu-2000 wekhebula le-optical futhi uwubeke ngesivinini esingamakhilomitha angu-200 ngosuku.

Ngaphambi kokubeka, kuyadingeka ukuhlola nokuhlanza umzila wamakhebula, ukuhlanza amanetha okudoba, izinto zokudoba nezinsalela, kumbiwe imisele yemikhumbi ehamba olwandle,

khulula ulwazi lokuzulazula olwandle, futhi uthathe izinyathelo zokuphepha.Umkhumbi wokwakha obeka ikhebula elingaphansi kwamanzi ulayishwe ngokugcwele izintambo ezihamba ngaphansi kolwandle

futhi ifinyelela endaweni emisiwe yolwandle engaba ngu-5.5km ukusuka esiteshini sesitimela.Ikhebula elingaphansi kwamanzi elibeka umkhumbi wokwakha lihamba nomunye

umkhumbi wokwakha osizayo, uqala ukuhlehlisa ikhebula, bese udlulisela ezinye izintambo emkhunjini wokwakha osizayo.

Ngemva kokuqedwa kokuhlehliswa kwekhebula, le mikhumbi emibili iqala ukubeka izintambo ezihamba ngaphansi kolwandle ibheke esiteshini.

Izintambo ezihamba ngaphansi kolwandle ekujuleni kolwandle zibekwe ngokunembile endaweni emisiwe yomzila ngemikhumbi emile eguquguqukayo efakwe ngokugcwele.

izinto zokwakha ezizenzakalelayo njengamarobhothi esilawuli kude sangaphansi kwamanzi kanye nokuma okuzenzakalelayo.

2. Enye ingxenye yomkhumbi obeka ikhebula elikhanyayo i-submarine excavator,ezobekwa ogwini ekuqaleni futhi ixhunywe

ekugcineni okugxilile kwekhebula le-optical.Umsebenzi wayo ufana negeja.Emakhebulini abonakalayo, yi-counterweight ewavumela ukuthi acwile olwandle.

I-excavator izodonswa phambili ngomkhumbi futhi iqedele imisebenzi emithathu.

Esokuqala siwukusebenzisa ikholomu yamanzi anomfutho ophezulu ukuze kususwe inzika phansi olwandle futhi kwakhe umsele wekhebula;

Okwesibili ukubeka ikhebula le-optical ngokusebenzisa imbobo yekhebula le-optical;

Okwesithathu ukungcwaba ikhebula, ukumboza isihlabathi ezinhlangothini zombili zentambo.

Kalula nje, umkhumbi obeka ikhebula ngowokubeka izintambo, kuyilapho i-excavator ingeyokubeka izintambo.Nokho, intambo ye-trans ocean optical iwugqinsi uma kuqhathaniswa

futhi iyavumelana nezimo, ngakho ijubane eliya phambili lomkhumbi kufanele lilawulwe ngokuqinile.

Ngaphezu kwalokho, olwandle olumangelengele, amarobhothi adingeka ukuthi ahlale ebona indlela engcono kakhulu yokuvimbela ukulimala kwamadwala ekhebulani.

Uma ikhebula elingaphansi kwamanzi lilimele, lilungiswa kanjani?

Ngisho noma ikhebula le-optical libekwe ngokuphelele, kulula ukulinyazwa.Kwesinye isikhathi umkhumbi udlula noma ihange lithinte intambo yokubona ngephutha,

nenhlanzi enkulu izolimaza ngephutha igobolondo lekhebula le-optical.Ukuzamazama komhlaba okwenzeka eTaiwan ngo-2006 kwadala umonakalo ezintamboni eziningi ze-optical, ngisho ne-

amabutho ezitha angalimaza ngamabomu izintambo ezibonayo.

Akulula ukulungisa lezi zintambo ze-optical, ngoba ngisho nomonakalo omncane uzoholela ekukhubazekeni kwezintambo ezibonakalayo.Kudingeka amandla amaningi kanye nezinto ezibonakalayo

izinsiza zokuthola igebe elincane emashumini ezinkulungwane zamakhilomitha wekhebula le-optical.

Ukuthola intambo yokubona enephutha enobubanzi obungaphansi kuka-10 cm ukusuka olwandle ngamakhulu noma izinkulungwane zamamitha ukujula kufana nokufuna

inaliti ku-haystack, futhi kunzima kakhulu ukuyixhuma ngemva kokulungiswa.

Ukuze ulungise ikhebuli yokubona, qala ngokuthola indawo yomonakalo ngokuthumela amasignali asuka ezintamboni zokukhanya kuzo zombili iziphetho, bese uthumela.

irobhothi ukuze lithole ngokunembile futhi linqamule le ntambo yokubona, futhi ekugcineni lixhume ikhebula lokukhanya eliyisipele.Nokho, inqubo yokuxhuma izoqedwa

phezu kwamanzi, futhi intambo yokubona izophakanyiselwa phezu kwamanzi ngesikebhe sokudonsa, futhi ixhunywe futhi ilungiswe unjiniyela ngaphambi kokuba

ibekwe olwandle.

Iphrojekthi yezintambo ezihamba ngaphansi kwamanzi ibonwa njengephrojekthi enkulu eyinkimbinkimbi futhi enzima yiwo wonke amazwe emhlabeni.
