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 bridgeyavela eBrithani, kukhona unjiniyela waseBrithani uDonald Bailey owasungulwa ngo-1938 phakathi nempi yezwe yesibili, izwe lakithi ekuqaleni kwawo-1960 laqala ukukhiqiza ibhuloho lomgwaqo onguthelawayeka onguthelawayeka 321, ibhuloho lensimbi le-Bailey libonakala ngesakhiwo esilula, izingxenye ezilula, izinto zokuhamba ezilula. , kodwa futhi inomthwalo omkhulu wokuthwala, ukuqina kwesakhiwo, impilo ende yokukhathala, ikakhulukazi esetshenziswa kwezokuthutha zamasosha, ukutakula kanye nokusiza izinhlekelele, ukwakhiwa kwezokuvikela kuzwelonke, ubunjiniyela bokongiwa kwamanzi, ukuhamba kwemigwaqo kanye neminye imikhakha.

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 amathimba okwakha asebenza emsebenzini wokuphambana phakathi nesikhathi sokwakha, imizamo yokuqapha ukuphepha kufanele iqiniswe, futhi kumiswe isikhulu esiqapha ukuphepha endaweni. . 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 kwezikafula kuzovikela imikhiqizo, futhi ukulimala kwezindonga, 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 yikhasimende kuqala, ukulethwa okusheshayo kwe-China amanani aphansi entengo esezingeni eliphezulu I-Custom Design Belle Bridge, kunoma ubani onentshisekelo ezisombululweni zethu noma ofuna ukukhuluma ngokuthenga ngokwezifiso, sicela uqiniseke ukuthi usithinta. 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.
