Ukuqinisa isakhiwo ngaphansi kwamanzi kudlala indima ebalulekile kubunjiniyela basolwandle kanye nokugcinwa kwengqalasizinda yasemadolobheni. I-glass fiber sleeve, i-epoxy grout engaphansi kwamanzi kanye ne-epoxy sealant, njengezinto ezibalulekile ekuqiniseni ngaphansi kwamanzi, zinezici zokumelana nokugqwala, amandla aphezulu kanye nokuphila isikhathi eside, futhi zisetshenziswa kabanzi emisebenzini yobunjiniyela. Leli phepha lizokwethula izici zalezi zinto, izimiso zokukhetha kanye nezindlela zokwakha ezihambisanayo.
I. Isikhwama se-Glass Fiber
Isikhafu sefayibha yengilazi uhlobo lwezinto zokwakha ezisetshenziselwa ukuqinisa ngaphansi kwamanzi, futhi izingxenye zaso eziyinhloko yilezii-fiber yengilazifuthii-resin. Inokumelana okuhle kakhulu nokugqwala, amandla aphezulu kanye nokuguquguquka okuhle, okungakhulisa ngempumelelo amandla okuthwala kanye nokusebenza kokuzamazama komhlaba kwesakhiwo. Lapho ukhetha imikhono ye-fiberglass, izici ezilandelayo kufanele zicatshangelwe:
1. Amandla nokuqina: Khetha izinga lamandla nokuqina elifanele ngokwezidingo zangempela zobunjiniyela.
2. Ububanzi nobude: Nquma ububanzi nobude obufanele besikhwama ngokuya ngobukhulu besakhiwo esizoqiniswa.
3.ukumelana nokugqwala: qinisekisa ukuthi isivikelo se-fiberglass singamelana namakhemikhali angaphansi kwamanzi kanye nokuguguleka kwamanzi olwandle.
II. i-grout epoxy engaphansi kwamanzi
I-grout ye-epoxy engaphansi kwamanzi iyinto ekhethekile yokugaya, ehlanganiswe kakhului-epoxy resinkanye ne-hardener. Inezici ezilandelayo:
1. Ukumelana namanzi: inokumelana namanzi okuhle kakhulu futhi ayithinteki yimvelo engaphansi kwamanzi.
2.ukubopha: ukukwazi ukwakha isibopho esiqinile ngesikhwama se-fiberglass nokuthuthukisa amandla aphelele esakhiwo.
3.ukuthamba okuphansi: uma ithamba liphansi, kulula ukulithulula nokugcwalisa inqubo yokwakha ngaphansi kwamanzi.
III. I-Epoxy sealant
I-Epoxy sealant isetshenziselwa ukuvala isivikelo se-fiberglass kuphrojekthi yokuqinisa ngaphansi kwamanzi, engavimbela ukungena kwamanzi nokugqwala. Izici zayo yilezi ezilandelayo:
1. Ukumelana namanzi: ukumelana namanzi okuhle, ukusetshenziswa kwamanzi isikhathi eside ngeke kwehluleke.
2.ukubopha: kungakha isibopho esiseduze nesigqoko sefayibha yengilazi kanye ne-grout ye-epoxy engaphansi kwamanzi ukuthuthukisa ubuqotho besakhiwo sephrojekthi.
Indlela yokwakha:
1. Ukulungiselela: Hlanza ubuso besakhiwo esiqinisiwe, qiniseka ukuthi ubuso abunazo izinsalela kanye nokungcola.
2. Ukufakwa kwesikhafu se-fiberglass: lungisa isikhafu se-fiberglass esakhiweni esiqinisiwe ngokwezidingo zomklamo.
3. Gcwalisa i-grout ye-epoxy engaphansi kwamanzi: sebenzisa imishini efanele ukufaka i-grout ye-epoxy engaphansi kwamanzi esikhwameni se-fiberglass, ugcwalise yonke indawo yesikhwama.
4.ukwelashwa kokuvala: sebenzisa i-epoxy sealer ukuvala zombili izinhlangothi zesikhafu se-fiberglass ukuvimbela ukungena komswakama.
Isiphetho:
Isikhindi sefayibha yengilazi, i-epoxy grout engaphansi kwamanzi kanye ne-epoxy sealant yizinto ezisetshenziswa kakhulu kumaphrojekthi okuqinisa ngaphansi kwamanzi. Zidlala indima ebalulekile emandleni okuthwala, ukusebenza kokuzamazama komhlaba kanye nokuqina kwezakhiwo eziqinisiwe. Empeleni, izinto ezifanele kufanele zikhethwe ngokuya ngezidingo ezithile zephrojekthi futhi zisetshenziswe ngokuhambisana nezindlela zokwakha ezifanele ukuqinisekisa ikhwalithi nokuthembeka kwephrojekthi yokuqinisa.
