II-HBD60-Uhloboibhuloho ladabuka eJalimane futhi langeniswa eChina ukuze likhiqizwe ngobuningi ngokuhlaziywa kwesakhiwo salo onjiniyela beGreat Wall.

Ukwethulwa kweI-HBD60-Uhloboibhuloho lisukela emigomeni yezobuchwepheshe kanye nokushoda kwe-Bailey Bridge. Njengoba kwaziwa yibo bonke, i-Belle Bridge iyisakhiwo esivamile sebhuloho lensimbi elakhiwe ngaphambili, okuyibhuloho elithwele ibhuloho elingaphezulu nangaphansi elinephini elilodwa elixhumanisa iyunithi ye-truss njengohlaka oluyinhloko lwesakhiwo sebhuloho, elinezinzuzo zesakhiwo esilula, ukuguquguquka okuqinile nokushintshana okuhle. Kodwa noma ngabe umthwalo ungemkhulu, ungafinyelela amamitha angama-60 kuphela ngespan eyodwa.

Ngakho-ke,I-Great Wall Groupwethula iI-HBD60-Uhloboibhuloho. Nakuba i-truss yamukela insimbi enkulu, isakhiwo silula, esingagcini nje ngokuba nenzuzo yokuguquguquka okuqinile kwebhuloho lensimbi le-Bailey elakhiwe ngaphambili, kodwa futhi lenza umkhawulo we-span, lithuthukisa ubude be-span eyodwa futhi lisindise izindleko ze-bridge pier. .

I-HBD60uhlobougongolo lwensimbi olwakhiwe ngaphambili luvamise ukuthatha uhlaka oluqinisiwe lwemigqa ephindwe kabili ngechord yesithathu, ehlanganiswa kusukela ezingxenyeni ezijwayelekile ezifana nezigxobo zokugcina, amasegimenti e-truss ajwayelekile, amachords, amachords aqinisiwe, amachord wesithathu, ama-crossbeam, izinduku zokubopha ezingazwani nomoya, nezisekelo eziqondile. I-truss eyinhloko ixhunywe ngama-bolts aphezulu. I-truss ejwayelekile ingu-3.048m ubude, inobude obuyingqimba eyodwa obungu-2.250m kanye nobude obukabili obuyi-4.500m. Kunama-trusses amabili ohlangothini olulodwa, futhi umgwaqo wenqola uthatha indawo yebhuloho likakhonkolo eliqinisiwe eliqiniswe endaweni noma idekhi yebhuloho lensimbi.

Ezokuthutha kanye Nokugcinwa kwe-HBD60 UhloboAmabhuloho Esakhiwo Sensimbi

I-1) Ngesikhathi sokulayisha, ukuthutha, kanye nenqubo yokukhipha izingxenye ngesikhathi sokuthunyelwa, kuyadingeka ukugwema ukulimaza ifilimu kapende, kanye nokulimala kokushayisana nokuguqulwa kwezingxenye.

I-2) Izindlela zokuthutha eziningi kufanele zisetshenziselwe ukuthutha ingxenye, futhi kungakhathaliseki ukuthi iyiphi enye esetshenziswayo, ukuhamba okuphakathi kufanele kuncishiswe.

3) Lapho uthumela izingxenye, umenzi kufanele anikeze umsebenzisi isitifiketi sekhwalithi yomkhiqizo, uhlu lwezingxenye zomkhiqizo, kanye nemiyalo yokusebenzisa ibhuloho lensimbi.

I-4) Ukugcinwa kwamabhuloho ensimbi kufanele kwenziwe ezindaweni zokugcina impahla, futhi ukuphathwa kwazo kufanele kwenziwe ngokuhambisana nezinhlinzeko ezifanele zeMithethonqubo Yokuphathwa Kwezindawo Zokuthwala Izinto Zokuvikeleka Kazwelonke kanye neManuwali Yokuphatha Yezindawo Zokugcinwa Kwempahla Yezokuvikela Kazwelonke. .

I-5) Ukuqinisekisa ukuxhuma okushelelayo kwama-bolts aphezulu phakathi kwezingxenye zebhuloho lensimbi, iyunithi yokucubungula kufanele ithathe izinyathelo ezisebenzayo nezinokwenzeka ukuvimbela ukuguqulwa kwengxenye ngesikhathi sokugcinwa nokuthuthwa kwezingxenye zebhuloho lensimbi.

I-6) Ngesikhathi sokugcinwa nokuthuthwa kwezingxenye, ukunakwa kufanele kukhokhwe ekuvikelweni kwendawo yokumboza isakhiwo sensimbi. Uma kukhona umonakalo, kufanele ulungiswe ngesikhathi. Iyunithi yokucubungula kufanele yakhe inqubo yokulungisa indawo enamathelayo ehlangabezana nezidingo zethu zokwakha.
