Assembly Df Ductile Cast Iron Pipe

Umhlangano DfI-Ductile Cast Iron Pipe

1. Ngaphambi kokuba umsele umbiwe, izithiyo endaweni yokumba kufanele zisuswe.
2. Ukuqinisekisa ukuthi inhlabathi ingagcwaliswa kahle ngokwanele endaweni engaphansi kwamapayipi ukuze kufakwe i-backfill esikhathini esizayo kufanele kucatshangelwe.Isikhala esiningi somsele kufanele sigcinwe ezindaweni ezihlangene zamapayipi ukuze kusebenze kalula.

   Ngaphandle kwesimo esikhethekile, umkhawulo womsele kufanele ube umugqa oqondile futhi umbhede kufanele ube sezingeni elifanayo.Lapho kumbiwa ngendlela yomshini, ungqimba lomhlabathi oluyi-0.2-0.3m kufanele luhlale ukuze lusetshenziswe ngesandla.

3. Ubukhulu bomsele (ngaphandle kwesiteji se-steel plate).
4. Usebenzisa ibhulashi locingo kanye neragi ehlanzekile, hlanza ngokucophelela ingaphakathi lesokhethi ikakhulukazi i-gasket recesses.Ikakhulukazi, susa noma yimaphi amadiphozithi omhlaba, isihlabathi, njll. futhi hlanza i-spigot yepayipi ukuze ihlanganiswe futhi i-gasket ngokwayo, ithole umkhawulo obushelelezi.
5. Ukuze uthole ipayipi lensimbi eliwugqinsi elithayiphiwe DN100~300mm, faka i-gasket egoqiwe ekugcineni kwesokhethi ukuze wenze ibhulokhi ebheke ebhuleki ishumekwe ngokuqinile esisekelweni, Cindezela ukuphuma kwe-gasket kuze kumiswe i-gasket ngokulinganayo kusokhethi.Epayipini elithayiphiwe ngenhla kwe-DN400mm, goba amaphethelo amabili e-gasket, bese ucindezela okubili okuphumela ngaphandle ngakunye, ngaleyo ndlela faka kalula i-gasket esisekelweni.Ubuso bangaphakathi bebhulokhi ebheke kumabhuleki abukwazi ukunwetshwa ukusuka kubhuleki lesokhethi.Hlola i-gasket efanele noma cha maqondana nenani elifanele.
6. Gcoba isikhombimsebenzisi se-gasket nesiphetho se-spigot.Ukugcotshwa kungaba amanzi anensipho noma ukuthambisa okune-alkali okungeyona ubuthi.
7. Faka i-spigot esokhethini uze uthinte i-gasket ku-ekseli efanayo.Kumelwe iqondiswe kahle ukuze i-ekseli emaphakathi yepayipi noma izixhumo ziqondane.Ngenkathi ixhuma ipayipi, ipayipi elihlukile lithatha amathuluzi ahlukene.Faka ipayipi ngokucophelela nangokuqhubekayo, uma amandla akhona amakhulu okumelana, ukuxhumana kwepayipi kufanele kumiswe ngokushesha bese ukhipha ipayipi bese uhlola indawo ye-gasket yerabha nesokhethi nesiphetho se-spigot.Ngemva kokukhipha izinkinga, faka futhi.Ukujula kokufaka okudingekayo kufanele kube phakathi kwemigqa emibili emhlophe.
8. Faka isikali esiqondile esikhaleni esiyindilinga phakathi kwesokhethi nodonga lwepayipi uze uthinte i-gasket yerabha futhi ulinganise ukujula ngisho noma cha eduze nomjikelezo wepayipi.Hlola amapayipi axhumene namanye ukuthi ahambisana yini ne-ekseli efanayo, ngaphandle kwalokho indawo engaphansi komsele kufanele ilungiswe ukuze kube nokungahambi kahle.
9. Ngemuva kokuhlanganisa ukuhlanganisa, maqondana nobubanzi lungisa ukuchezuka kwe-angular okufanele kwenelise izimfuneko ezishiwo ohlwini olulungile.
10. Ukugcwaliswa ngemuva: Ngokuvamile, ukuhlola okudingekayo kwepayipi kufanele kuhlolwe ingcindezi yamanzi ngemva kokuba wonke agcwaliswe ngemuva, ikakhulukazi, amalunga angeke agcwaliswe ngemuva, kodwa ingxenye ephakathi yepayipi kufanele igcwaliswe ngemuva ngokuphelele ukuze kugwenywe ukunyakaza kwamapayipi ngaphambi kokuhlolwa.Akudingekile ukukhetha umhlaba ozogcwaliswa ngemuva, kuyilapho ingxenye ethinta ipayipi ngokuqondile yayinesihlabathi esikhethwe kangcono noma umhlaba ocolekile ngenkathi kumbiwa.Qaphela ukuthi kuzo zombili izinhlangothi zepayipi kufanele zonke zigcwaliswe ngesihlabathi, ngokufanayo nephansi lepayipi, ikakhulukazi zama ukukhipha amanzi angaphansi komhlaba futhi ugweme ukwehla kwepayipi ngemva kokufakwa.
