Inxalenye ikholamu yekhonkrithi ngaphantsi nangaphantsi weld, isakhiwo esilula, i pedestal ebekelwe indebe edla ngokusetyenziswa kwikhonkrithi ngesiseko intonga-uhlobo ikholamu ufake unyawo, nto leyo ilula kakhulu izityalo yokuvelisa, lo gama icandelo encinane ubunzima, ezothutho. kwaye Ukuphakamisa kwakhona kulula, ulwakhiwo ilula, iintsika zekhonkrithi kunye nentsimbi baba ravioli sheet eliqengqelekayo, ubukhulu ipleyiti ayikho enkulu, ngokubanzi ngaphantsi kwe-40m, kungakhathaliseki ukuba indawo yefektri ukuwelda kunye docking, akukho nzima.Kwangaxeshanye, xa kuthelekiswa nentsika yekhonkrithi eyomeleziweyo engundoqo, ulusu lwentsimbi lwekholam yekhonkrithi luye lwaqiniswa umsebenzi, indima yazo zombini ii-stitrups zentsimbi ezinde kunye neziguquguqukayo, ngokunjalo yenze ityhubhu yangaphakathi yentsimbi, izinto zokonga kunye nentsimbi yentsimbi kunye nothotho lokuqiniswa, Kwakhona, ngenxa yokuba umbhobho webhatyi yekholomu ngokwawo uchasene noxinzelelo olusecaleni lwethemplethi, kodwa kwakhona ugcine i-formwork kunye neenkqubo zokususa iifom.Kwiminyaka yakutshanje, ukumpompa ngezitena okuqhelekileyo, okugalelwe kwisiza akukho bunzima, bendalo kunye nokusetyenziswa okubanzi kwePaola engashukumiyo iindlela zokwakha zekhonkrithi, indawo elungelelanisiweyo - amanyathelo abambekayo, ulwakhiwo olulula.Kwindawo esezantsi yoluhlu kwakhona uvule umngxuma wokunkcenkceshela okwexeshana kunye nempompo yekhonkrithi yokugalela indlela yekhonkrithi ezantsi-up, kungekuphela nje ngokukhawuleza, kodwa nokuqinisekisa umgangatho wokunkcenkceshela.Ngaphezu koko, emva kokugalela umbhobho wentsimbi kwiimeko zokufuma ezizinzileyo, amanzi akakwazi ukujika, ukuphelisa imfuneko yeenkqubo zokulondoloza amanzi, ukwenza lula inkqubo yokunyanga ikhonkrithi.

Kwimveliso yamacandelo ensimbi, iimfuno zokufakela:

①iikholamu zekhonkrithi kunye nombhobho wentsimbi, iimfuno zokuvelisa i-welding ephezulu.Jikelele kufuneka zinikwe ngqangi spiral welding umbhobho, spiral welded umbhobho xa kungekho, ungasebenzisa kwakhona ibhedi yabo roll rolling steel, kodwa iikhoyili zentsimbi ulwalathiso oluqengqelekayo kufuneka perpendicular ukuya kwicala ububanzi lombhobho kunye neemfuno ezithile.Welding steel imveliso ukongeza kwiimfuno jikelele ukuqinisekisa ngokungqongqo ityhubhu flat, ngqo, ngaphandle warping, umhlwa umphezulu kunye namanqaku ukothuka.Ngokukodwa udonga lombhobho walo weemfuno zomhlwa.Inokunyusa umjikelo wemveliso yentsimbi;

②kwinkqubo yokuvelisa icandelo, intsimbi yentsimbi inzima.Iimfuno zesakhiwo umlenze emva kokuwelda umbhobho kufuneka ngqo, nto leyo efuna ukuthatha amanyathelo afanelekileyo xa i-soldering kunye ne-welding yengqwalasela ekhethekileyo kunye nokuqwalasela umyalelo we-welding deformation effect.I-tube butt weld umlenze ngaphambili, kuba umbhobho omncinci onqumlayo kufuneka udityaniswe.Kuba umbhobho ubukhulu enkulu kufuneka ibe enye kunye ukomeleza ezongezelelweyo welding welding okwethutyana fixed-linking welding.Kwinkqubo ye-welding ye-steel butt, ukuba ifunyenwe i-tack-welded seam ekuveleni kwe-micro-cracks, isayithi le-microcracks kufuneka liphelise yonke i-welding kwakhona.Ukuze kuqinisekiswe umgangatho we-weld joint of the, kwindawo ye-splicing kwi-joint joints kwi-joint joints kufuneka umise i-liner eyongezelelweyo.Kwikholam yelathiyisi ukuya kubungakanani obufunekayo kunye ne-engile isinxibelelanisi iibhubhu amalungu amalungu kunye ezahlukeneyo webs kufuneka ichanekile.Ngokukodwa i-webs ye-gap kwi-joint yombhobho kunye nelungu kufuneka isetyenziswe i-intersection curve i-curve yokusika umatshini wokusika umbhobho ngokuhambelana nobubanzi besiphelo sombhobho kunye ne-engile yoqhagamshelwano lomphezulu wombhobho usike indawo.Ukuba akukho matshini wokusika i-automatic sheet metal kufuneka ukwandiswe umbono wokusika ukusika.Ngokuqhelekileyo zisetyenziselwa izakhiwo eziphakamileyo kwipayipi ehlengahlengiswayo, i-tube butt ehlengahlengiswayo inzima yokwakha, ukulungelelaniswa kwisakhiwo se-node sinzima kakhulu, ngokuqinisekileyo kuya kuchaphazela inkqubela phambili yolwakhiwo.
