Ukulawulwa kwekhwalithi yokufakwa kwePipeline Ukufakwa eChina ikakhulukazi kufaka phakathi: Isigaba sokulungiselela ukwakhiwa, isigaba sokwakha, isigaba sokuhlola, isivivinyo sokuhlola, ukuhlanza amapayipi nokuhlanza nokuhlanza indawo yokuhlanza nokuhlanza nokuhlanza indawo yokuhlanza nokuhlanza indawo yokuhlanza kanye nokuhlanza indawo yokuhlanza nokuhlanza nokuhlanza kanye nesigaba sokuhlanza kanye nokuhlanza indawo yokuhlanza kanye nesigaba sokuhlanza nokuhlanza kanye nokuhlanza isigaba. Ngezidingo ezengeziwe zobuchwepheshe, ekwakhiweni kwangempela, kufanele silungiselele, silungiselele, silawule futhi silwa nokulwa nokuwohloka komsebenzi ngokwesimo sangempela.

1. Thola uhlelo lokufaka lwePipeline yenqubo

Ngaphambi kokuthi kunqunywe inqubo yepayipi, inani eliyisisekelo lokufakwa kwephrojekthi nokwakha kumele lichazwe ngokuya ngokufakwa kanye nokwakhiwa kwesiza nokwakha. Izinsizakusebenza eziphambili zabantu nezinto zokwakha zizoqinisekiswa ngokukwazi kahle isimo sokuthuthukiswa kwephrojekthi yonke kanye nezinto eziphambili kanye nezinsizakusebenza zabantu zeyunithi yokwakha. Ngohlelo lohlelo lwezinto ezibonakalayo kanye namandla, kwabelwa ukwabiwa okuphelele. Ngaphansi kwesimo sokuqinisekisa inqubekela phambili yokwakha, inqubo ehambisanayo izohleleka futhi ihlelwe ukusindisa abasebenzi bezokwakha futhi balwele isikhathi sokwakha, ukuze bathuthukise ukusebenza kahle kwemishini emikhulu efana ne-crane.

Njengephuzu eliyisihluthulelo sokulungiselela uhlelo lokwakha, uhlelo lobuchwepheshe lubandakanya ikakhulukazi: uhlelo olunembile lokuphakamisa kanye nesicelo senqubo ye-welding. Lapho u-welding wezinto ezikhethekile futhi ukhuphukela amapayipi amakhulu abubanzi, incazelo yezobuchwepheshe yohlelo lokwakha kumele ithuthukiswe, futhi isisekelo esithile semiyalo sizothathwa njengesisekelo sokwakhiwa kwesayithi nokufakwa. Okwesibili, ngokusho kwekhwalithi yokuqukethwe kweSikimu sokwakha kanye nezindlela zokuqinisekisa ukuphepha, uhlelo lokwakha lunganqunywa ngokuhlanganisa zonke izici zezinto, futhi indawo izoqondiswa kahle futhi ihlelekile ukwakhiwa okuhambisanayo.

2. Ukusebenza kwePipeline Preabrication Technology ekwakhiweni

Njengenqubo evamile eChina, inqubo yokuxhumana ngepayipi kufanele inakekele ngenxa yokujula kokuphambuka kokungaphambi kokuphamba kanye nobungako obuphansi bokuqala. Isibonelo, amanye amaphrojekthi wokwakha ahlongoza ukuthi inqubo yamapayipi kumele ibe ngaphezu kwama-40%, okuthuthukisa kakhulu ubunzima bamabhizinisi wokwakha ngokuya ngesimo sangempela. Njengokuxhumeka okusemqoka kokufakwa kwepayipi kwe-Pipeline, ukujula kwe-preakricution kusekuhlelweni okulula kokuqondisa phambili kumabhizinisi amaningi eChina. Isibonelo, inqubo yokusebenzisa phambili yesigaba samapayipi aqondile nge-elbow kanye nokuxhumeka okubili kwepayipi futhi umuntu angaxazulula inkinga elula yokufaka yepayipi. Lapho kufakwa imishini yamapayipi, akunakudlala indima yokuqanjwa kwepayipi. Ngakho-ke, ekwakhiweni kwangempela, kufanele sivikele inqubo yokwakha ngaphambi kwesikhathi, bese sifaka igobolondo elihambisanayo elihlanganisiwe esimweni sokufaka se-Mercury kanye nokushisa i-Exchanger ngaphansi kwezimo. Emkhakheni owenziwe ngoMkhandlu ngaphambi komhlangano, lapho umhlangano wensimu usuqediwe, amalunga we-welding weqembu le-welding yendawo adonswa emuva esitshalweni esihambelanayo sokuqamba, kanti nemishini ezenzakalelayo isetshenziselwa ngqo ukufudumala, futhi i-flange ehambisanayo ixhumeke ngama-bolts . Ngakho-ke, umsebenzi we-welding wezandla esizeni sokwakha ungasindiswa futhi ukusebenza kahle kwepayipi kungathuthukiswa.
