Ukomelezwa kweglasi phantsi kwamanzi okukhetha imikhono yefayibha kunye neendlela zokwakha

Ukomelezwa kolwakhiwo lwangaphantsi kwamanzi ludlala indima ebalulekileyo kubunjineli baselwandle kunye nokugcinwa kweziseko ezingundoqo zasezidolophini. Umkhono wefiber yeglasi, i-epoxy grout engaphantsi kwamanzi kunye ne-epoxy sealant, njengezinto eziphambili zokuqiniswa kwamanzi, zineempawu zokuxhathisa ukubola, amandla aphezulu kunye nobomi benkonzo ende, kwaye zisetyenziswa ngokubanzi kubunjineli bobunjineli. Eli phepha liza kwazisa iimpawu zezi zinto, imigaqo yokukhetha kunye neendlela zokwakha ezihambelanayo.

I. I-Glass Fiber Sleeve

Umkhono wefayibha yeglasi luhlobo lwemathiriyeli eyakhiweyo esetyenziselwa ukomeleza ngaphantsi kwamanzi, kwaye iinxalenye zayo eziphambiliifayibha yeglasikwayeintlaka. Inokumelana ne-corrosion egqwesileyo, amandla aphezulu kunye nokuguquguquka okuhle, okunokunyusa ngokufanelekileyo umthamo wokuthwala kunye nokusebenza kwe-seismic yesakhiwo. Xa ukhetha imikhono yefiberglass, ezi zinto zilandelayo kufuneka ziqwalaselwe:
1.Amandla kunye nokuqina: Khetha amandla afanelekileyo kunye nenqanaba lokuqina ngokweemfuno zobunjineli zangempela.
I-2.I-Diameter kunye nobude: Qinisekisa ububanzi obufanelekileyo kunye nobude bomkhono ngokobukhulu besakhiwo esimele siqiniswe.
3.ukumelana nokubola: qinisekisa ukuba umkhono we-fiberglass unokumelana neekhemikhali kwindawo engaphantsi kwamanzi kunye nokukhukuliseka kwamanzi olwandle.

II. ngaphantsi kwamanzi epoxy grout

I-epoxy grout engaphantsi kwamanzi yinto ekhethekileyo yokuhluza, ngokukodwa iqulunqweepoxy resinkunye ne-hardener. Inezi mpawu zilandelayo:
I-1.ukuchasana kwamanzi: inokumelana nokugqwesa kwamanzi kwaye ayichatshazelwa yindawo engaphantsi kwamanzi.
I-2.bonding: ikwazi ukwenza ibhondi eqinile kunye nomkhono we-fiberglass kunye nokuphucula amandla onke esakhiwo.
I-3.i-viscosity ephantsi: kunye ne-viscosity ephantsi, kulula ukuthulula kwaye ugcwalise inkqubo yokwakhiwa kwamanzi.

III. Epoxy sealant

I-Epoxy sealant isetyenziselwa ukutywina umkhono we-fiberglass kwiprojekthi yokuqinisa ngaphantsi kwamanzi, enokuthintela ukungena kwamanzi kunye nokuhlwa. Iimpawu zayo zezi zilandelayo:
I-1.ukuchasana kwamanzi: ukuchasana kwamanzi okulungileyo, ukusetyenziswa kwexesha elide ngaphantsi kwamanzi akuyi kuphumelela.
I-2.bonding: inokwenza ikhonkco elisondeleyo kunye nomkhono wefiber yeglasi kunye ne-epoxy grout engaphantsi kwamanzi ukuphucula ingqibelelo yesakhiwo seprojekthi.

Indlela yokwakha:

I-1.Ukulungiselela: Coca umphezulu wesakhiwo esomeleziweyo, qinisekisa ukuba umphezulu awunayo i-debris kunye nokungcola.
2.Ukufakwa kwe-fiberglass sleeve: lungisa umkhono we-fiberglass kwisakhiwo esomeleziweyo ngokweemfuno zoyilo.
3.Gcwalisa i-epoxy grout engaphantsi kwamanzi: sebenzisa izixhobo ezifanelekileyo ukufaka i-epoxy grout engaphantsi kwamanzi kwi-sleeve ye-fiberglass, ugcwalise yonke indawo yomkhono.
Unyango lwe-4.sealing: sebenzisa i-epoxy sealer ukutywina zombini iziphelo zomkhono we-fiberglass ukuthintela ukungena kokufuma.

Isiphelo:

Umkhono wefiber yeglasi, i-epoxy grout engaphantsi kwamanzi kunye ne-epoxy sealant zizinto eziqhelekileyo ezisetyenziswa kwiiprojekthi zokuqinisa ngaphantsi kwamanzi. Badlala indima ebalulekileyo kumandla okuthwala, ukusebenza kwe-seismic kunye nokuqina kwezakhiwo eziqiniweyo. Ngokusebenza, izinto ezifanelekileyo kufuneka zikhethwe ngokweemfuno ezithile zeprojekthi kwaye zisebenze ngokuhambelana neendlela zokwakha ezihambelanayo zokuqinisekisa umgangatho kunye nokuthembeka kweprojekthi yokuqinisa.
