Ingxenye yekholomu kakhonkolo incane futhi incane ukushisela, isakhiwo esilula, isisekelo esibekelwe inkomishi evame ukusetshenziswa kukhonkolo ngesisekelo sonyawo lokufaka ikholomu yohlobo lwenduku, okuyizitshalo zokukhiqiza ezilula, kuyilapho isisindo sengxenye encane, ezokuthutha. futhi Ukuphakamisa futhi kulula, ukwakhiwa kulula, izinsika zikakhonkolo nezensimbi zaziyishidi eligoqiwe le-ravioli, ukushuba kwepuleti akukukhulu, ngokuvamile ngaphansi kwama-40m, kungakhathaliseki ukuthi i-welding site yefektri kanye ne-docking, ayinabo ubunzima.Ngesikhathi esifanayo, uma kuqhathaniswa namakholomu kakhonkolo aqinisiwe ayisihluthulelo, isikhumba sensimbi sekholomu kakhonkolo siqinise umsebenzi, indima yakho kokubili ama-stirrps ensimbi e-longitudinal kanye ne-transverse, kanjalo ne-steel yangaphakathi yeshubhu, okonga impahla kanye ne-steel banding kanye nochungechunge lokuqiniswa, Futhi, ngenxa yokuthi ipayipi yejacket yekholomu ngokwayo imelana nokucindezela kwe-lateral kwesifanekiso, kodwa futhi londoloza i-formwork kanye nezinqubo zokususa ifomu.Eminyakeni yamuva nje, ukupompa izitini okuvamile, okuthululelwe esizeni abukho ubunzima, bokudala nokusetshenziswa kabanzi kwezindlela zokwakha zikakhonkolo zePaola ezingadlidliziwe, isiza esilula kakhulu - izinyathelo zikakhonkolo, ukwakhiwa okulula.Engxenyeni engezansi yekholomu ibuye ivule imbobo yokuchelela yesikhashana ngokuthululwa kwephampu kakhonkolo yendlela yokufika phansi, hhayi nje ngokushesha, kodwa futhi nokuqinisekisa izinga lokunisela.Ngaphezu kwalokho, ngemva kokuthela ipayipi lensimbi ezimweni zomswakama ozinzile, amanzi awakwazi ukuhwamuka, aqede isidingo sezinqubo zokongiwa kwamanzi, enze inqubo yokuphulukisa kakhonkolo ibe lula.

Ekukhiqizeni izingxenye zensimbi, izidingo zokufaka:

①amakholomu kakhonkolo ngepayipi lensimbi, izidingo zokukhiqiza eziphezulu zokushisela.Okujwayelekile kufanele kunikezwe kuqala Kuvunguza ashiselwe ipayipi, Kuvunguza ashiselwe ipayipi lapho kungekho, ungase futhi usebenzise umbhede wabo roll rolling steel, kodwa amakhoyili steel rolling isiqondiso kufanele perpendicular isiqondiso ububanzi tube futhi ube nezidingo ezithile.Welding steel ukukhiqizwa ngaphezu izidingo jikelele ukuqinisekisa ngokuqinile tube flat, iqonde, ngaphandle warping, ukugqwala ebusweni kanye shock marks.Ikakhulukazi ipayipi layo odongeni izidingo nokugqwala.Kungase kwandise umjikelezo wokukhiqiza insimbi;

②enqubweni yokukhiqiza ingxenye, i-steel butt inzima.Izidingo zesakhiwo isitho ngemva Welding ipayipi kumele iqonde, okudinga ukuthatha isinyathelo esifanele lapho soldering kanye Welding of ukunakwa okukhethekile futhi ukucabangela oda Welding deformation effect.I-tube butt weld umlenze ngaphambili, ngoba ipayipi eliwububanzi obuncane kufanele lishiselwe.Ukuze ipayipi elikhulu ububanzi kufanele kube omunye ukuqinisa ezengeziwe ashiselwe steel tube okwesikhathi fixed-oxhumanisa Welding.Enqubweni yokushisela izinqe zensimbi, uma kutholakala i-tack-welded seam lapho kuvela imifantu emincane, isiza se-microcracks kufanele siqede konke ukushiselwa kabusha.Ukuze kuqinisekiswe ikhwalithi ye-weld joint of the, endaweni yesehlakalo ukuhlanganisa emajoyini amapayipi kumele kumise liner eyengeziwe.Ukuze ikholomu ye-lattice ibe usayizi odingekayo kanye ne-engeli yokuhlanganisa isixhumi amashubhu ezitho kanye nezinhlobonhlobo zamawebhu kufanele zinembile.Ikakhulukazi igebe webs at the joint ipayipi kanye umlenze kufanele kusetshenziswe empambana ijika ipayipi othomathikhi cutting umshini ngokusho ububanzi ekupheleni ipayipi kanye angle of contact surface ipayipi ukusika isikhala.Uma kungekho othomathikhi ishidi metal ukusika imishini kufanele kwandiswe umbono staking out ukusika.Okuvame ukusetshenziswa ezakhiweni eziphakeme kakhulu kumapayipi aguquguqukayo, i-tube butt eguquguqukayo inzima yokwakha, ukulungiswa esakhiweni se-node kuyinkimbinkimbi, ngokungangabazeki kuzothinta inqubekelaphambili yokwakhiwa.
