Ukuqinisa ulwakhiwo olungaphantsi kwamanzi kudlala indima ebalulekileyo kubunjineli bezolwandle kunye nokugcinwa kweziseko zedolophu. I-glass fiber sleeve, i-underwear epoxy grout kunye ne-epoxy sealant, njengezinto eziphambili ekuqiniseni okungaphantsi kwamanzi, zineempawu zokumelana nokugqwala, amandla aphezulu kunye nobomi obude benkonzo, kwaye zisetyenziswa kakhulu kwimisebenzi yobunjineli. Eli phepha liza kwazisa iimpawu zezi zinto, imigaqo yokukhetha kunye neendlela zokwakha ezifanelekileyo.
I. Isingxobo seFayibha yeGlasi
Isingxobo sefayibha yeglasi luhlobo lwezixhobo zokwakha ezisetyenziselwa ukuqinisa phantsi kwamanzi, kwaye izinto zayo eziphambili zeziifayibha yeglasikwayei-resin. Inokumelana nokugqwala okugqwesileyo, amandla aphezulu kunye nokuguquguquka okuhle, okunokunyusa ngempumelelo amandla okuthwala kunye nokusebenza kwenyikima yesakhiwo. Xa ukhetha imikhono yefiberglass, kufuneka kuqwalaselwe ezi zinto zilandelayo:
1. Amandla nokuqina: Khetha amandla nokuqina okufanelekileyo ngokweemfuno zobunjineli zokwenyani.
2. Ububanzi kunye nobude: Chonga ububanzi kunye nobude obufanelekileyo besleeve ngokwesayizi yesakhiwo esiza kuqiniswa.
3.ukumelana nokugqwala: qinisekisa ukuba isingxobo se-fiberglass sinokumelana neekhemikhali ezikwimeko engaphantsi kwamanzi kunye nokukhukuliseka kwamanzi olwandle.
II. i-epoxy grout engaphantsi kwamanzi
I-epoxy grout engaphantsi kwamanzi yinto ekhethekileyo yokugquma, eyenziwe ikakhului-epoxy resinkunye ne-hardener. Ineempawu ezilandelayo:
1. Ukumelana namanzi: inokumelana namanzi okugqwesileyo kwaye ayichaphazeleki yimeko engaphantsi kwamanzi.
2.ukubopha: ukukwazi ukwakha ukubopha okuqinileyo ngesingxobo sefiberglass nokuphucula amandla esakhiwo ngokubanzi.
3.i-viscosity ephantsi: xa i-viscosity iphantsi, kulula ukuyigalela nokuzalisa inkqubo yokwakha phantsi kwamanzi.
III. I-Epoxy sealant
I-Epoxy sealant isetyenziselwa ukuvala isingxobo se-fiberglass kwiprojekthi yokuqinisa amanzi phantsi kwamanzi, enokuthintela ukungena kwamanzi kunye nokugqwala. Iimpawu zayo zezi zilandelayo:
1.ukuxhathisa amanzi: ukuxhathisa amanzi kakuhle, ukusetyenziswa kwamanzi ixesha elide akuyi kusilela.
2.ukubopha: kunokwenza umanyano olusondeleyo nesingxobo sefayibha yeglasi kunye ne-epoxy grout engaphantsi kwamanzi ukuphucula ukuthembeka kwesakhiwo seprojekthi.
Indlela yokwakha:
1. Ukulungiselela: Coca umphezulu wesakhiwo esiqinisiweyo, qiniseka ukuba umphezulu awunazo inkunkuma kunye nongcoliseko.
2. Ukufakelwa kwesingxobo se-fiberglass: lungisa isingxobo se-fiberglass kwisakhiwo esiqinisiweyo ngokweemfuno zoyilo.
3. Zalisa i-epoxy grout engaphantsi kwamanzi: sebenzisa izixhobo ezifanelekileyo ukufaka i-epoxy grout engaphantsi kwamanzi kwisingxobo se-fiberglass, ugcwalise yonke indawo yesingxobo.
4.unyango lokutywina: sebenzisa i-epoxy sealer ukutywina zombini iziphelo zesingxobo se-fiberglass ukuthintela ukungena komswakama.
Isiphelo:
Isingxobo sefayibha yeglasi, i-epoxy grout engaphantsi kwamanzi kunye ne-epoxy sealant zizinto ezisetyenziswa rhoqo kwiiprojekthi zokuqinisa phantsi kwamanzi. Zidlala indima ebalulekileyo kumthamo wokuthwala, ukusebenza kwe-seismic kunye nokuqina kwezakhiwo eziqinisiweyo. Ngokwesiqhelo, izixhobo ezifanelekileyo kufuneka zikhethwe ngokweemfuno ezithile zeprojekthi kwaye zisetyenziswe ngokuhambelana neendlela zokwakha ezifanelekileyo ukuqinisekisa umgangatho kunye nokuthembeka kweprojekthi yokuqinisa.
