Umbhobho wentsimbi odibeneyo ojikelezayo ongaphantsi komhlaba wegesi yendalo
Yazisa:
Imibhobho yegesi yendalo engaphantsi komhlaba idlala indima ebalulekileyo ekuhambiseni olu butyebi buxabisekileyo emakhayeni, kumashishini nakwimizi-mveliso. Ukuqinisekisa ukhuseleko nokusebenza kakuhle kwale mibhobho, kubalulekile ukusebenzisa izixhobo ezifanelekileyo kunye neenkqubo zokuwelda ngexesha lokwakha. Siza kuhlola ukubaluleka kwemibhobho yentsimbi eweldiweyo ejikelezayo kunye nokubaluleka kokulandela iinkqubo ezifanelekileyo zokuwelda imibhobho xa usebenza nayo.umbhobho wegesi yendalo ongaphantsi komhlaba.
Umbhobho odibeneyo ojikelezayo:
Umbhobho odibeneyo ojikelezayo uthandwa kakhulu ekwakhiweni kwemibhobho yegesi yendalo engaphantsi komhlaba ngenxa yamandla ayo angaphakathi kunye nokuqina kwayo. Le mibhobho yenziwa ngokugoba umcu wentsimbi oqhubekayo ube yimo ejikelezayo uze uyidibanise kwimithungo. Isiphumo kukuba imibhobho enezihlanganisi eziqinileyo nezivaliweyo ezinokumelana noxinzelelo olukhulu lwangaphandle kwaye zilungelelanise neentshukumo zomhlaba. Olu lwakhiwo lukhethekileyo lwenzaumbhobho wentsimbi odibeneyo ojikelezayoilungele imibhobho engaphantsi komhlaba apho uzinzo lubaluleke kakhulu.

Uvavanyo lwe-Hydrostatic
Ubude bombhobho ngamnye buya kuvavanywa ngumvelisi kuxinzelelo lwe-hydrostatic oluya kuvelisa eludongeni lombhobho uxinzelelo olungaphantsi kwama-60% wamandla aphantsi okuvelisa kubushushu begumbi. Uxinzelelo luya kugqitywa yile equation ilandelayo:
P=2St/D
Utshintsho Oluvumelekileyo Kubunzima Nobukhulu
Ubude bombhobho ngamnye buya kulinganiswa ngokwahlukeneyo kwaye ubunzima bawo abuyi kwahluka ngaphezu kwe-10% ngaphezulu okanye i-5.5% phantsi kobunzima bawo obuqikelelwayo, obubalwe kusetyenziswa ubude bawo kunye nobunzima bawo ngobude beyunithi nganye.
Ububanzi bangaphandle abuyi kwahluka ngaphezu kwe-±1% ukusuka kububanzi obuqhelekileyo bangaphandle.
Ubukhulu bodonga nangaliphi na ixesha abuyi kuba ngaphezulu kwe-12.5% phantsi kobukhulu bodonga obuchaziweyo.
Ubude
Ubude obungacwangciswanga obunye: 16 ukuya kwi-25ft (4.88 ukuya kwi-7.62m)
Ubude obuphindwe kabini obungacwangciswanga: ngaphezulu kwe-25ft ukuya kwi-35ft (7.62 ukuya kwi-10.67m)
Ubude obufanayo: umahluko ovumelekileyo ±1in
Iphela
Iipayipu mazifakelwe iziphelo ezingenanto, kwaye iziphelo ezisemaphethelweni mazisuswe.
Xa isiphelo sepayipi esichazwe njengesiphelo se-bevel, i-engile mayibe ngama-30 ukuya kuma-35 degrees
Iinkqubo zokuwelda imibhobho:
Efanelekileyoiinkqubo zokuwelda imibhobhozibalulekile ekuqineni nasekukhuselekeni kwemibhobho yegesi yendalo engaphantsi komhlaba. Nazi izinto ezimbalwa ezibalulekileyo ekufuneka ziqwalaselwe:
1. Iziqinisekiso zoMthumeli:Kufuneka kuqeshwe abawelda abafanelekileyo nabanamava, ukuqinisekisa ukuba baneziqinisekiso kunye nobuchule obufunekayo bokusingatha iinkqubo ezithile zokuwelda ezifunekayo kwimibhobho yegesi yendalo. Oku kunceda ukunciphisa umngcipheko weziphene zokuwelda kunye nokuvuza okunokwenzeka.
2. Ukulungiswa kunye nokucoca amalungu:Ukulungiswa okufanelekileyo kwamalungu kubalulekile ngaphambi kokuba kudityaniswe. Oku kuquka ukususa naluphi na ukungcola, inkunkuma okanye izinto ezingcolisayo ezinokuchaphazela kakubi ukuthembeka kwamalungu. Ukongeza, ukuqaqambisa imiphetho yepayipi kunceda ekudaleni amalungu adityaniswe ngokuqinileyo.
3. Iindlela zokuwelda kunye neeparameter:Iindlela zokuwelda ezichanekileyo kunye nemilinganiselo kufuneka ilandelwe ukuze kufunyanwe ii-welds ezisemgangathweni ophezulu. Inkqubo yokuwelda kufuneka iqwalasele izinto ezinje ngobukhulu bombhobho, indawo yokuwelda, ukwakheka kwegesi, njl. Kucetyiswa ukusebenzisa iinkqubo zokuwelda ezenzekelayo ezifana nokuwelda kwe-arc yentsimbi yegesi (GMAW) okanye ukuwelda kwe-arc engaphantsi komhlaba (SAW) ukuqinisekisa iziphumo ezihambelanayo kunye nokunciphisa iimpazamo zomntu.
4. Uhlolo noVavanyo:Ukuhlolwa nokuvavanywa ngokupheleleyo kwe-weld kubalulekile ukuqinisekisa umgangatho kunye nokuthembeka kwayo. Iitekhnoloji ezifana novavanyo olungonakalisiyo (NDT), kubandakanya uvavanyo lwe-X-ray okanye lwe-ultrasound, zinokubona naziphi na iziphene ezinokubakho ezinokuthi zibeke emngciphekweni ukuthembeka kwexesha elide kombhobho.
Ukuququmbela:
Ukwakhiwa kwemibhobho yegesi yendalo engaphantsi komhlaba kusetyenziswa umbhobho wentsimbi odibeneyo ojikelezayo kufuna ukuthotyelwa kweenkqubo ezifanelekileyo zokuwelda imibhobho. Ngokuqesha abawelda abafanelekileyo, ukulungiselela ngononophelo iindawo zokudibanisa, ukulandela iindlela ezifanelekileyo zokuwelda, nokwenza uhlolo olucokisekileyo, sinokuqinisekisa ukhuseleko, ukuqina, kunye nokusebenza kakuhle kwale mibhobho. Ngokuqwalasela ngenyameko iinkcukacha kwinkqubo yokuwelda, sinokuhambisa igesi yendalo ngokuzithemba ukuhlangabezana neemfuno zamandla zoluntu lwethu ngelixa sibeka phambili impilo-ntle yokusingqongileyo kunye nokhuseleko loluntu.
