Xa ubeka i-thin-walledimibhobho yentsimbi engenasici, kufuneka zifakwe emva kokuba imisebenzi yoluntu igqityiwe.Ngaphambi kokufakela, okokuqala, khangela ukuba indawo yomngxuma ogciniweyo ichanekile.

Xa ubeka imibhobho yensimbi engenasici, umgama phakathi kwenkxaso esisigxina akufanele ube mkhulu kune-15mm.Umgama phakathi kwezixhaso ezisisigxina zemibhobho yamanzi ashushu kufuneka umiselwe ngokwesixa sombhobho wokwandiswa kwe-thermal kunye nembuyekezo evumelekileyo yokwandiswa kwamalungu.Inkxaso emiselweyo kufuneka ibekwe kwi-diameter eguquguqukayo, isebe, i-interface, kunye namacala omabini odonga oluthwele kunye ne-slab yomgangatho.Ukufakwa kwenkxaso ehambayo kwimibhobho yensimbi engenasici enqabileyo iya kuhlangabezana neemfuno zenkcazo yoyilo kunye nemizobo.

Izibophelelo zemibhobho yesinyithi okanye ii-hangers kufuneka zisetyenziswe ukulungisa imibhobho yentsimbi ecekeceke engenasici kwimibhobho yokuhambisa amanzi nakwiindawo zokuhambisa amanzi;iintambo zombhobho okanye i-hangers kufuneka zibekwe kumgama we-40-80mm ukusuka kwizinto zokufakelwa.

Xa ubeka imibhobho yensimbi engenasici, i-casing pipes kufuneka ifakwe xa imibhobho idlula emgangathweni.Imibhobho yeplastiki kufuneka isetyenziswe kwimibhobho ye-casing;imibhobho yentsimbi yentsimbi kufuneka isetyenziswe xa uwela uphahla.Imibhobho ye-casing kufuneka ibe yi-50mm phezulu kunophahla kunye nomhlaba, kwaye amanyathelo angqongqo angangeni manzi kufuneka athathwe.Kwimibhobho efihliweyo, uvavanyo loxinzelelo kunye neerekhodi zokwamkelwa ezifihliweyo ziya kwenziwa ngaphambi kokutywinwa.Emva kokuphumelela uvavanyo loxinzelelo kunye nokuthatha amanyathelo okukhusela i-corrosion, i-M7.5 i-cement mortar ingasetyenziselwa ukuzaliswa.

Xa ubeka imibhobho yensimbi engenasici, akufuneki kubekho ukugoba kwe-axial kunye nokuphazamiseka, kwaye akukho kulungiswa okunyanzelekileyo xa udlula kwiindonga okanye phantsi.Xa uhambelana neminye imibhobho, umgama wokukhusela kufuneka ugcinwe njengoko kufuneka.Xa uyilo lungachazwanga, umgama ocacileyo akufanele ube ngaphantsi kwe-100mm.Xa imibhobho ihambelana, umbhobho obhityileyo owenziwe ngentsimbi engenasici kumsele wemibhobho kufuneka ulungelelaniswe ngaphakathi kumbhobho wentsimbi.
