Amathangi Kamanzi Ensipho Angcwatshwa Emhlabeni: Umhlahlandlela Wobunjiniyela Nokuklama
Ithangi likadoti lensimbi engagqwali engcwatshwa emhlabathini yisisombululo sokugcina esisezingeni eliphezulu, esiqinisekile esenzelwe izindawo lapho izimo zomhlaba zilimaza kakhulu, amazinga amanzi angaphansi komhlaba aphakeme, noma izinto eziqukethwe (udoti/imfucumfucu yezimboni) zilimaza izinto. Ngokungafani namathangi ajwayelekile enziwe ngekhonkrithi noma i-fiberglass reinforced plastic (FRP), insimbi engagqwali inikeza ukuqina okungafani, ukumelana nomlilo, kanye nendawo engavimbeli ukungena kwamanzi evimbela ukungcola nokuvuza.
1. Ukukhethwa Kwezinto: Kungani Insimbi Engagqwali?
Udoti ulimaza amakhemikhali, uqukethe ama-sulfides, ama-chlorides, namazinga ahlukahlukene e-pH angonakalisa izinto ezijwayelekile ngokuhamba kwesikhathi.
● SS316L (Kunconyiwe): Ngodoti ongcwatshwa emhlabathini, i-Grade 316L iyizinga legolide. Ukwengezwa kwe-molybdenum kunikeza ukumelana okungcono kakhulu nokugqwala okubangelwa yi-chloride pitting kanye ne-crevice corrosion, ezivame kakhulu emanzini angcolile.
● SS304: Ifanele kuphela ezinhlelweni ezithile kakhulu, eziphathwe kahle zamanzi angcolile. Ngokuvamile ayinconywa ukungcwatshwa kwamanzi angcolile angafunwanga ngenxa yengozi enkulu yokugqwala.
● Ingaphezulu Elingathinteki: Ukuqedwa okubushelelezi, okungavimbeli izimbobo kuvimbela ukuqoqeka kwama-"fatbergs" (ukwakheka kwamafutha/okuqinile) kanye ne-biofilm, okwenza ithangi libe lula kakhulu ukulihlanza nokulihlola.
2. Ubuqotho Bokwakhiwa: Inkinga "Engaphansi Komhlaba"
Umkhawulo oyinhloko wobunjiniyela bethangi elingaphansi komhlaba akuwona nje uketshezi ngaphakathi, kodwa ingcindezi yenhlabathi ngaphandle.
● Ingcindezi Yangaphandle Ye-Hydrostatic: Ezindaweni ezinamanzi amaningi, ithangi kumele lenziwe ukuze limelane nokudonsela phezulu (ukuntanta) kanye nemiyalezo eqeda amandla.
● Ukuqinisa Okwakhiwayo: Ngokungafani namathangi angaphezulu komhlaba, amathangi ensimbi engagqwali angcwatshwa emhlabeni kumele aqiniswe ngezimbambo zangaphakathi noma izinsika zangaphandle ukuze kuvinjelwe ukuthi izindonga zingadilizwa umthwalo wobumba.
● Izidingo Zokugcwalisa: Ubunjiniyela obunembayo budinga izinto zokugcwalisa ezithile (ngokuvamile itshe elincane noma isihlabathi esihlanzekile) ukuze kuqinisekiswe ukusatshalaliswa okulinganayo komfutho ezindongeni zamathangi.
3. Imephu Yokuqhathanisa: Izinto Zamathangi
Lapho kuchazwa ithangi, onjiniyela baqhathanisa izinto ngokusekelwe ezindlekweni zesikhathi eside zokuphila kunokuba intengo yokuqala yokuthenga.
Isici | Insimbi Engagqwali | Ukhonkolo | I-Fiberglass (FRP) |
Ukumelana Nokugqwala | Kuhle kakhulu | Mbi (Izikhala/Iziqhephu) | Phakathi (Ingozi ye-Osmosis) |
Ubuqotho Bokwakhiwa | Phakathi Kakhulu | Phezulu (uma kuqinisiwe) | Phakathi (Iphuka kalula) |
Isivinini Sokufakwa | Phakathi | Kancane (Kudingeka ukuqina) | Ngokushesha |
Isikhathi Sokuphila | Iminyaka engu-50+ | Iminyaka engu-20–30 | Iminyaka engu-15–25 |
Ingozi Yokuvuza | Cishe Ayikho | Phezulu (Ama-micro-cracks) | Phakathi (Ukuphuka komthungo) |
4. Izinto Ezibalulekile Zokuklama
Ukuqinisekisa ukuthi uhlelo lwakho lwe-underground sewage luhlala lusebenza amashumi eminyaka, qinisekisa ukuthi incazelo yakho yobunjiniyela ihlanganisa lezi zinto:
1. Ukuvikelwa Nge-Cathodic: Ngisho nensimbi engagqwali, i-anode yokuhlatshelwa (i-zinc noma i-magnesium) ingafakwa uma i-chemistry yenhlabathi ibucayi kakhulu (i-acidity ephezulu noma okuqukethwe usawoti).
2. Ukufinyelela Nezimbobo Zokungena: Amathangi angaphansi komhlaba kumele abe nezingxenye zokukhuphuka ezifinyelela phezulu, ezihlome ngezingubo eziqinile, ezingavimeli igesi namanzi ukuze kuvinjelwe ukuphuma kwamavungi nokungena kwamanzi.
3. Ukungenisa Umoya: Indle ivimbela amagesi e-methane ne-hydrogen sulfide. Uhlelo oluqinile lokungenisa umoya alunakugwenywa ukuze kuvinjelwe ukwanda kwengcindezi yangaphakathi nokuqoqeka kwamagesi ayingozi.
4. Ukuvimbela Ukuntanta: Uma izinga lamanzi liphezulu, ithangi kumele liboshwe ku-pad yensimbi eyenziwe nge-concrete ukuze lingaphumi emhlabeni uma lingenawo amanzi.
5. Imibuzo Evame Ukubuzwa (FAQ)
Q: Kungani kukhokhwa imali eningi nge-stainless steel uma ukhonkolo noma ipulasitiki kuneshibhile?
A: Ukhonkolo unemingqikilimba; umunca amakha endle futhi ungagqabuka ngokuhamba kwesikhathi, okuholela ekungcolisweni kwamanzi angaphansi komhlaba. Ipulastiki/ifayibha ingaba nomonakalo wesakhiwo ngaphansi kwemithwalo enzima yenhlabathi. I-stainless steel iyimali "yesikhathi esisodwa"; inikeza izindleko eziphansi zokuba nayo isikhathi eside eminyakeni engu-30+ ngoba ayidingi ukulungiswa noma ukufakwa esikhundleni.
Q: Ingabe lezi tanki zingasetshenziswa ezinhlelweni ze-septic?
A: Yebo, kodwa ngokuvamile ziyadudula ezinhlelweni ze-septic zasekhaya ezijwayelekile. Ziyisinqumo esikhethwayo ezinhlelweni zikamasipala, ezokuhweba, noma zezimboni lapho ukwehluleka kwesakhiwo noma ukuvuza kubeka isibopho esikhulu somthetho noma esemveleni.
Q: Ngiyazi kanjani ukuthi i-tanki ye-stainless engaphansi komhlaba iyavuza?
A: Ngoba zisemhlabeni, awukwazi "ukubona" ukuvuza. Ukufakwa kufaka izimbobo zokuqapha noma ukusetshenziswa kwemiklamo yamathangi anezindonga ezimbili (anenqola yokuthola ukuvuza) ukuze kunikezwe isaziso esisheshayo nganoma yikuphi ukwephulwa.
Amathangi ezindlebe ensimbi engagqwali angaphansi komhlaba ayisinqumo esihamba phambili sokuqina kwengqalasizinda nokuvikelwa kwemvelo. Ngokukhetha izinga elifanele lensimbi (SS316L) nokuqinisekisa ukuthi umklamo wesakhiwo ubheka ingcindezi yenhlabathi ne-hydrostatic, udala uhlelo oluqinile, olungavuzi ukuvuza olunciphisa izikweletu zesikhathi eside ezihambisana nengqalasizinda yezindlebe engaphansi komhlaba esikhulile.
Ngabe njengamanje usezigabeni zokuklama iphrojekthi yamanzi angcolile angaphansi komhlaba, futhi udinga usizo lokubala ubukhulu odongeni lwesakhiwo oludingekayo obujulile benhlabathi yakho nomthwalo othize?
