Umbhobho wenkqubo udlala indima ebalulekileyo kumandla, iikhemikhali, i-petrochemical, i-metallurgy kunye nezinye iiyunithi zokuvelisa. Inkqubo yokufakela ihambelana ngokuthe ngqo nomgangatho weprojekthi kunye nomthamo wokhuseleko. Kwinkqubo yofakelo lombhobho, iteknoloji yenkqubo yombhobho yiprojekthi eneemfuno eziphezulu zobugcisa kunye nenkqubo yokufakela enzima kakhulu. Umgangatho wokufakelwa kwemibhobho uchaphazela ngokuthe ngqo umgangatho wenkqubo yokuthutha, ayichaphazeli kuphela inkqubo yokuthutha imveliso, kodwa idlala indima enkulu emsebenzini. Ngoko ke, kwinkqubo yokufakelwa kwemibhobho yenkqubo, umgangatho wofakelo kufuneka ulawulwe. Eli phepha lixoxa kwaye lichaza ulawulo lofakelo lwemibhobho kunye neengxaki ekufuneka ziqwalaselwe kwintsimi yofakelo lombhobho eChina.
Umbhobho womoya oxiniweyo
Ukulawulwa komgangatho wokufakwa kwemibhobho yenkqubo e-China ikakhulu kubandakanya: isigaba sokulungiselela ukwakhiwa, isigaba sokwakha, isigaba sokuhlola, uvavanyo lokuhlola, ukuhlanjululwa kwemibhobho kunye nenqanaba lokucoca. Ngokunyuka kweemfuno zobugcisa, kulwakhiwo lwangempela, kufuneka silungiselele, sifake, silawule kunye nomsebenzi wokulwa nokubola ngokwemeko yangempela.
1. Ukumisela iskimu sofakelo lombhobho wenkqubo
Ngaphambi kokuba kumiselwe inkqubo yokufakelwa kombhobho, ubungakanani obusisiseko bokufakelwa kweprojekthi kunye nokwakhiwa kufuneka kuchazwe ngokwemiqathango yokufakela kunye nokwakhiwa kwendawo kunye noyilo lokwakha. Imithombo ephambili yoluntu kunye nezinto eziphathekayo zokwakhiwa ziya kuqinisekiswa ngokulawula yonke imeko yophuhliso lweprojekthi kunye neyona nto ibalulekileyo kunye nezibonelelo zabasebenzi beyunithi yokwakha. Ngolungiselelo lwenkqubo yezinto eziphathekayo kunye nabasebenzi, ulwabiwo olubanzi lwenziwa. Phantsi komqathango wokuqinisekisa inkqubela phambili yolwakhiwo, inkqubo ehambelanayo iya kucwangciswa kwaye ilungiselelwe ukugcina abasebenzi bokwakha kunye nokuzabalazela ixesha lokwakha, ukuze kuphuculwe ukusebenza kakuhle koomatshini abakhulu abafana nekhreyini.
Njengenqaku eliphambili lokulungiswa kweskimu sokwakha, iskimu sobugcisa sibandakanya ikakhulu: iskimu sokuphakamisa ngokuchanekileyo kunye nesicelo senkqubo ye-welding. Xa i-welding yezixhobo ezikhethekileyo kunye nokuphakanyiswa kwemibhobho yobubanzi obukhulu, inkcazo yobugcisa yeskimu sokwakha kufuneka iphuculwe, kwaye isiseko esithile sokhokelo siya kuthathwa njengesiseko sokwakhiwa kwesiza kunye nokufakwa. Okwesibini, ngokweskimu somxholo weskimu sokwakha umgangatho kunye namanyathelo okuqinisekisa ukhuseleko, iskimu sokwakha sinokumiselwa ngokudibanisa yonke imiba yezinto, kwaye isiza siya kukhokelwa ngokufanelekileyo nangokucwangcisiweyo kulwakhiwo oluhambelanayo.
2. Ukusetyenziswa kweteknoloji ye-pipeline prefabrication kulwakhiwo
Njengenkqubo eqhelekileyo e-China, inkqubo yokwenziwa kwemibhobho yangaphambili kufuneka inikwe ingqwalasela ngenxa yobunzulu obungafezekanga bokucwangciswa kwangaphambili kunye nobungakanani obuphantsi be-prefabrication. Ngokomzekelo, ezinye iiprojekthi zokwakha ziphakamisa ukuba ukwakhiwa kwangaphambili kwemibhobho kufuneka kube ngaphezu kwe-40%, ephucula kakhulu ubunzima bamashishini okwakha ngokweyona meko. Njengekhonkco eliphambili lofakelo lombhobho wenkqubo, ubunzulu bokwenziwa busekwinkqubo elula yolwakhiwo kumashishini amaninzi eTshayina. Ngokomzekelo, inkqubo yokucwangciswa kwangaphambili kwecandelo lombhobho ochanekileyo kunye ne-elbow kunye nombhobho ukudibanisa ezimbini kunye nomnye unokusombulula ingxaki yokufakela elula yombhobho wenkqubo. Xa izixhobo zokubhobhoza zifakwe, azikwazi ukudlala indima yokwenziwa kombhobho kwangaphambili. Ngoko ke, kulwakhiwo lwangempela, kufuneka sicinge ngenkqubo yokwakha kwangaphambili, kwaye sifake igobolondo ehambelanayo ehambelanayo kwindawo yokufakela i-mercury kunye nobushushu bokushisa phantsi kweemeko. Kumbhobho wokudityaniswa kwentsimi yangaphambili, xa udibaniso lwentsimi lugqityiwe, idibansi yokuwelda yeqela lentsimi elifanisiweyo litsalwa emva kwiplanti ehambelanayo, kwaye izixhobo ezizenzekelayo zisetyenziselwa ukuwelda, kwaye iflange ehambelana nayo idityaniswe neebholiti. . Ngaloo ndlela, umsebenzi we-welding manual kwisiza sokwakha unokugcinwa kwaye ukufakwa kakuhle kombhobho kunokwandiswa.
