Yiziphi izinyathelo zokuphepha okufanele zinakwe ekwakhiweni kweBailey Bridge?

I-Bailey beam iyisigxobo se-truss esakhiwe uhlaka lwe-Bailey, olwakhiwe kakhulu ngokuxhunywa kwamafasitela ezimbali, bese lulungiswa ngamabhawudi.I-Bailey beam ilula futhi iyashesha ekwakhiweni kobunjiniyela, njenge-gantry crane, iplatifomu yokwakha, ibhuloho lomgwaqo wobunjiniyela, njll.

I-Bailey steel bridgeesuka eBrithani, ingabe unjiniyela waseBrithani uDonald Bailey wasungulwa ngo-1938 phakathi nempi yezwe yesibili, izwe lethu ekuqaleni kweminyaka yo-1960 laqala ukukhiqizwa kwezinto zokuhamba ngezempi, kodwa futhi linokuthola inhlekelele, ukwakhiwa kwenhlekelele, ukwakhiwa kwezenhlekelele, ubunjiniyela bezokuvikela amanzi, traffic traffic kanye nezinye izinkambu.

Ukubukeka kwePele Bridge kuthakaselwe iningi lonjiniyela, iPele Bridge yinhle, kodwa ohlelweni lokwakha, sidinga futhi ukunaka ezinye zezinyathelo zayo zokuphepha.

Izinyathelo eziyisithupha zokuphepha zokwakhiwa kwe-Bailey Bridge

1. Izingxenye eziyinhloko zeshidi le-Bere zakhiwe izingxenye ezine: ucezu lwe-truss, iphini lokuxhuma i-truss, uhlaka lokusekela kanye ne-truss bolt.Ilungu ngalinye elicindezelekile le-Bailey truss piece lixhunywe yi-truss kanye nohlaka lokusekela, olukhiqizwa ngu-no.8 Umkhiqizi wensimbi enohlaka olujwayelekile lwama-90cm.Lonke ucezu lwe-truss luhlanganiswe ucezu lwe-Bailey truss ngokusebenzisa izikhonkwane zokugcina.

2. Phakathi nenqubo yokumisa ugongolo oluthambekile lwebhuloho, ngenxa yokuthi amaqembu okwakha asebenza emsebenzini wokuphambana phakathi nenkathi yokwakhiwa kwenani eliphakeme, imizamo yokuqapha ukuphepha kufanele iqiniswe, futhi kumiswe isikhulu esiqapha ukuphepha esizeni.Izinto zokuthutha ezivundlile nezime mpo kufanele zihlinzekwe ngezindawo zokuxwayisa zesikhashana, ezinonxantathu obomvu nomhlophe obiyelwe ifulegi elincane.Qaphela izisebenzi ezingezona ezokwakha zingangeni.

3. Izinto zokumisa zomzimba wohlaka zincike kakhulu ekudluliselweni mathupha kanye nengxenye yokuthutha i-crane.Ukuze kuqinisekiswe ukudluliswa kwazo zonke izinto zokwakha, izisebenzi zokwakha kufanele zibambisane ne-crane ukuze ziphakanyiswe ngokuphepha nangokucophelela.Ukudlulisa ngesandla, ukwenza umsebenzi omuhle wokuzivikela, bopha ibhande lokuphepha, i-echo, thatha kuqala bese uthumela.Vimbela ngokuqinile ukufakwa kwamapayipi nezinsimbi ukuthi zingawi phansi.

4. Ngesikhathi sokwakhiwa kwe-scaffolding, ukuze kuvinjwe izinto eziwela phansi futhi zilimaze abantu, akufanele kube nezimbobo kuhlaka.Ngesikhathi sokumiswa, inetha lokuphepha kufanele limbozwe kuqala, bese kuthi cha.Izintambo ezihlabayo eziyi-18 kufanele ziboshwe ngamaphuzu amane, kungabi bikho into ethambile.Azikho izixhumi zepayipi ezengeziwe nezibophelelo ezizovunyelwa ukuvimbela ukuwa nokulimala.

5. Ukumiswa nokususwa kwesikafula kuzovikela imikhiqizo, futhi umonakalo ezindongeni, amafasitela, ingilazi kanye nezinsiza kuzokwenqatshelwa ngokuphelele.Izinto ezisetshenziswayo kufanele zipakishwe endaweni ebekiwe, futhi umsebenzi wokuhlanza izandla kufanele wenziwe nsuku zonke.

6. Izisebenzi zokwakha kufanele zisebenzise ngokuqinile izindinganiso zikazwelonke nezezimboni, futhi zithobele imithethonqubo efanele yokuphepha kanye nemithetho nemithetho ehlukahlukene yomnikazi kanye nomnyango wephrojekthi.Yamukela ngokungathí sina ukuhlolwa kokuphepha kwabanikazi nokugadwa, futhi wamukele ngenkuthalo nangokujulile ukulungiswa.

Sihlala sibeka okulindelwe ngamakhasimende kuqala, ukulethwa okusheshayo kwe-China amanani abizayo aphansi ekhwalithi ephezulu I-Custom Design Belle Bridge, kunoma ubani onentshisekelo kuzisombululo zethu noma ofuna ukukhuluma ngokuthenga ngokwezifiso, sicela uqiniseke ukuthi usithinte.Ngaphezu kwalokho, sineqembu labaphathi nezingcweti ezisezingeni eliphezulu abenza imikhiqizo yeqophelo eliphezulu futhi abanekhono lokuthuthukisa imikhiqizo emisha ukuze bandise izimakethe zethu zasekhaya nezamazwe ngamazwe.Sibheke ngabomvu ukuba khona kwamakhasimende amasha namadala, kanye nentuthuko yethu efanayo.
