Umbhobho wokuthuthwa kwamanzi angaphandle: iimpawu

Umbhobho we- sewerage wangaphandle okwenziwa rhoqo ngePVC. Le nkcazelo ibonakalise kakuhle kumashishini amaninzi. Iququzelela kakhulu ubunzima bomkhiqizo, obuchaphazela ngokufanelekileyo ukuhamba ngexesha lokuthutha nokupakisha. Ukumelana ngokungapheli kwamabhobho e-PVC ukubola kukubaluleke kakhulu.

Umbhobho wokuthuthwa kwamanzi emzimbeni wangaphandle ukusuka kwi-PVC unokuqwalaselwa njengesisombululo esiphezulu, kuba kule meko kukho umlinganiselo "olungcono wemilinganiselo". Le mibhobho iyakwazi ukwenza inkqubo enye kunye nomhlaba ojikelezayo, onokuyithatha imithwalo, inempahla yokuzihlanza, kunye ne-coefficient yokwandisa kule meko iphantsi kakhulu. Ukuthuthwa kwamanzi angaphandle kunomthwalo omkhulu kunokuba ungaphakathi, ngoko iipayipi kufuneka zenziwe ngepolymer enegunya eliphezulu. Iindonga zeemibhobho ezinjalo zenziwe ngokulinganayo ukuba ububanzi bungama-millimitha angama-110-200, kunye ne-three-layered, ukuba ububanzi buyi-250-500 millimeters. Kwimeko yesibini, uluhlu oluphakathi luyenziwe ngezinto zobucibu.

Umbhobho wokuthuthwa kwamanzi angaphandle ungenziwa kwi-asbestos-samente, insimbi yentsimbi, i-polyethylene. Uhlobo lo kuqala lunalo luncedo olunjengexabiso elincinci kwaye luthembeka, kodwa lugqabile, yingakho kukho iingxaki zokuthutha. Iipolphpropylene iipayipi zingaphelela ngaphezu kwehafu yeshumi.

Unokuqwalasela uhlobo olunjani lwamabhobho okuthuthwa kwamanzi okuhambisa amanzi ngaphandle. I-asbestos-samente iveliswa kwi-asbestos fiber kunye ne-Portland samente. Isisindo sabo sincinci ngokwaneleyo, amandla aphakamileyo, ahlala esheleleka ixesha elide, ukwenzela ukuba ukuphuma kwexesha kuhlale . Ukuyibeka kulula kakhulu.

Umbhobho we-ceramic yangaphandle yokucoca i-sewerage ayisebenzisi kaninzi. Nangona kunjalo, ngokwemigangatho yentsebenzo, iyakwazi ukugqithisa intsimbi. Iibhobho ezinjalo zizinzile, zigcina kakuhle ukukhanya kwe-surface yangaphakathi, azichaphazelekayo kwiinkqubo ezonakalisayo. Ubude obufutshane kunye nobuqhekeko yizona ziphene ezingundoqo. Inani elincinci lamalungu alwamkelekanga kwimibhobho ende.

Inketho yeklasi ifakwe iipayipi zensimbi. Zithembeke kakhulu, zinamandla amashishini kunye namachiza. Kwinkqubo yokufakela kwabo, kusetyenziswa amanxeba ensimbi, anokuqinisekisa ukuba unxibelelwano onokwethenjelwa kwiimeko zokutywinwa okuchanekileyo. Ubunzima obunzima-apha ubunqongophala obaluleke kakhulu beephayibhile, inkqubo ebaluleke kakhulu yokufakela kwabo. Ukuba kuyimfuneko yokubeka i-system- diameter system , ngoko ayikwazi ukuphathwa ngaphandle kokusetyenziswa kwezixhobo ezikhethiweyo zokuphakamisa.

Iibhobho ze-PVC zokuthuthwa kwamanzi angaphandle zivame ukusetyenziswa. Olu khetho lunemivuzo eninzi:

• Iindleko eziphantsi;
• Ukulula kokufakela;
• Ukunyanzelana kwamachiza;
• Ukuzinza.

Zonke ezi mpawu kwaye zenze le ndlela ikhetheke kakhulu kwiinjongo ezahlukeneyo.
