•Imboni yamakhemikhali: ukuthuthwa koketshezi noma amagesi angaboli (izinto ezisetshenziswayo kufanele zikhethwe ngokwendlela yokuxhumana).
Ubunjiniyela bokwakha kanye nesakhiwo
•Uhlaka lwesakhiwo: lusetshenziselwa ukusekela amakholomu, imishayo, ama-trusses, njll. ezakhiweni zesakhiwo sensimbi.
•I-scaffolding: isetshenziswa njengensika eqondile noma isigxobo esivundlile se-scaffolding elula, okulula ukuyakha ngokushesha.
•Uthango kanye nezinsimbi zokuvikela: njengamapayipi okusekela izindawo zokwakha kanye nezinsimbi zokuvikela umgwaqo.
Ukukhiqizwa kwemishini
•Indlu yemishini: njengesakhiwo sohlaka lwendlu yefeni kanye ne-air conditioner.
•Imishini yokudlulisa: izingxenye ezithwala umthwalo ezingacindezeli kakhulu njengezithutha zokuhambisa kanye nemishayo yokushayela.
Izimoto kanye nezokuthutha
•Ishasi yemoto: izingxenye zesakhiwo samaloli amancane nama-trailer.
•Izindawo zokuhamba: amapayipi okusekela izingodo zezibani zasemgwaqweni kanye nezigxobo zezimpawu zomgwaqo.
Ezinye izinkambu
•Ukukhiqiza ifenisha: izinhlaka zefenisha yensimbi (njengemashalofu namadokodo).
•Ubunjiniyela bamandla: imikhono yokuvikela ikhebula, izingxenye zesakhiwo sombhoshongo wokudlulisa.
Imininingwane yamamodeli epayipi ahlanganisiwe ngomthungo oqondile
Imininingwane yamapayipi ahlanganisiwe ngomthungo oqondile ivame ukuhlukaniswa ngobubanzi bangaphandle (OD), ubukhulu bodonga (WT), kanye nezinto zokwakha, futhi ilandela amazinga omhlaba wonke noma kazwelonke. Okulandelayo ukuhlukaniswa okuvamile kanye nemininingwane ejwayelekile:
1. Ukuhlukaniswa ngenqubo yokukhiqiza
Ukushisela ukumelana nemvamisa ephezulu (ipayipi le-ERW):
•Inqubo: Sebenzisa ugesi ovame kakhulu ukushisa umphetho wepuleti lensimbi bese ushisela ngaphansi kwengcindezi.
•Izici: Ukushisela okuncane, ukusebenza kahle okuphezulu, kufanelekile kumapayipi anezindonga ezincane (ubukhulu bodonga ≤ 20mm).
•Isicelo: Ukuthuthwa koketshezi olunomfutho ophansi, ukwesekwa kwesakhiwo.
Ukushisela i-arc okucwiliswe emanzini (Ipayipi le-LSAW, umthungo oqondile wokushisela i-arc engaphansi kwamanzi enamacala amabili):
• Inqubo: Kusetshenziswa ubuchwepheshe bokushisela i-arc ecwiliswe emanzini, izinhlangothi zombili ziyashiselwa, futhi amandla okushisela aphezulu.
• Izici: Ubukhulu bodonga bukhulu kakhulu (ngokuvamile ≥6mm), bufanelekela izikhathi zokucindezela okuphezulu noma umthwalo omkhulu.
• Ukusetshenziswa: Amapayipi kawoyela negesi ahamba ibanga elide, amaphrojekthi amakhulu ezakhiwo.
