Ukuqiniswa kwamanzi angaphansi kwamanzi kudlala indima ebalulekile ekwakheni kwengqalasizinda yasolwandle kanye nokugcinwa kwengqalasizinda yasemadolobheni. I-Glass Fibre Sleeve, I-Underwater Epoxy Grout ne-Epoxy Sealant, njengezinto ezisemqoka ekuqinisweni kwamanzi ngaphansi kwamanzi, zinezici zokuphikiswa kokugqwala, amandla aphezulu kanye nokuphila kwenkonzo ende, futhi kusetshenziswa kabanzi ekusebenzeni kobunjiniyela. Leli phepha lizokwethula izici zalezi zinto zokwenziwa, izimiso zokukhetha kanye nezindlela zokwakha ezihambisanayo.
I. I-Glass Fiber Sleeve
I-Glass Fibre Sleeve uhlobo lwesakhiwo esisetshenziselwa ukuqiniswa kwamanzi ngaphansi kwamanzi, futhi izingxenye zalo eziphambili zikhonaingilazi fiberna--minzana. Inokumelana kahle nokugqwala okuhle, amandla aphezulu nokuguquguquka okuhle, okungakhulisa ngempumelelo amandla okuthela nokuzamazama komhlaba kwesakhiwo. Lapho ukhetha imikhono ye-fiberglass, lezi zinto ezilandelayo kufanele zibhekwe:
1.Strefthth kanye Stiffness: Khetha amandla afanele namazinga okuqina ngokuya ngezidingo zangempela zobunjiniyela.
I-2.Diameter nobude: Thola ububanzi obufanele nobude besikhonkwane ngokuya ngosayizi wesakhiwo okufanele baqiniswe.
I-3.Corrosion Ukumelana: Qinisekisa ukuthi umkhono we-fiberglass ungamelana namakhemikhali endaweni engaphansi kwamanzi kanye nokuguguleka kwamanzi olwandle.
II. Underwater opoxy grout
I-Underwater Epoxy Grout iyinto ekhethekile yokulahla, eyakhiwa ikakhulukazii-epoxy resinkanye ne-hardiner. Inezici ezilandelayo:
Ukumelana namanzi: Kunokumelana okuhle kwamanzi futhi akuthinteki ngemvelo engaphansi kwamanzi.
I-2.Bonding: Uyakwazi ukwakha isibopho esiqinile nesikhonkwane se-fiberglass futhi athuthukise amandla aphelele esakhiwo.
3.Low Viscosity: Ngokubonakala okuphansi, kulula ukuthela nokugcwalisa inqubo yokwakha ngaphansi kwamanzi.
III. I-Epoxy Sealant
I-Epoxy Sealant isetshenziselwa ukubopha uphawu lwe-fiberglass sleeve kuphrojekthi yokuqinisa amanzi ngaphansi kwamanzi, okungavimbela ukungena kwamanzi kanye nokugqwala. Izici zalo zimi ngokulandelayo:
Ukumelana namanzi: Ukumelana kwamanzi okuhle, ukusetshenziswa kwamanzi okuhlala isikhathi eside ngeke kwehluleke.
I-2.Bonding: Ingakha isibopho esiseduze ngengilazi ye-fiber sleeve kanye ne-underwater epoxy grout ukwenza ngcono ubuqotho besakhiwo sephrojekthi.
Indlela yokwakha:
I-1.Prepation: Hlanza ingaphezulu lesakhiwo esiqinisiwe, qiniseka ukuthi ingaphezulu lingenamfutho kanye nokungcola.
2.I-2.I-2.Installation of Fiberglass Sleeve: Lungisa umkhono we-fiberglass esakhiweni esiqinisiwe ngokuya ngezidingo zokwakhiwa.
3.Gcina i-Underwater Epoxy Grout: Sebenzisa imishini efanelekile yokufaka i-epoxy ye-epoxy engaphansi kwamanzi ku-fiberglass sleeve, ugcwalise sonke isikhala.
I-4.Sealing Treatment: Sebenzisa i-Epoxy Sealer ukubeka uphawu zombili izinhlangothi ze-fiberglass sleeve ukuvikela ukungena komswakama.
Isiphetho:
I-Glass Fibre Sleeve, I-Underwater Epoxy Grout ne-Epoxy Sealant zivame ukusetshenziswa kwezinto ezisetshenziswayo kumaphrojekthi wokuqiniswa ngaphansi kwamanzi. Badlala indima ebalulekile ekusebenzeni kwamandla, ukusebenza kokuzamazama komhlaba nokuqina kwezakhiwo eziqinisiwe. Ekusebenzeni, izinto ezifanele kufanele zikhethwe ngokuya ngezidingo ezithile zephrojekthi futhi zisebenza ngokuya ngezindlela zokwakha ezihambisanayo zokuqinisekisa ikhwalithi nokwethembeka kwephrojekthi yokuqinisa.
