Izixazululo Zesisekelo Samathangi Okugcina Ensipho Engagqwalisiwe: Umhlahlandlela Wobunjiniyela
Izitsha zokugcina ezakhiwe ngensimbi engagqwali ziyizimpahla ezibalulekile ezisetshenziswa ikakhulukazi ezindaweni ezihlanzekile (zokudla/iziphuzo/imithi) kanye nezindawo ezinokubola kakhulu (ezamakhemikhali). Ngokungafani nezitsha zensimbi ye-carbon, ukwakhiwa kwesisekelo sesitsha sensimbi engagqwali kufanele kubheke ukuhlukaniswa kwezinto kanye nokunwebeka kwezinga lokushisa ukuze kuvinjelwe ukungcola kanye nokubola kwe-galvanic. Isixazululo esiphumelelayo sesisekelo sezitsha zensimbi engagqwali sibeka phambili ubuqotho besikhumba sesitsha kanye nokuhlanzeka kwendawo ezungezile.
1. Inkinga Ebalulekile: Ukuhlukaniswa Kwezinto
Umehluko omkhulu phakathi kwezisekelo zezitsha zensimbi ye-carbon nezensimbi engagqwali yisidingo sokuvimbela ukubola kwe-galvanic kanye nokungcola kwe-ferrous.
● Gwema Izinsimbi Ezingafani: Insimbi engagqwali akumele yothintane ngqo nensimbi ye-carbon eqinisayo noma izinto ezifakwe ngaphakathi kwesisekelo.
● Ukuphathwa Komswakama: Ukhonkolo olumanzi lungaba yindawo yokuhlala yama-ion e-chloride, angabangela ukuqhekeka kokugqwala okubangelwa ukucindezeleka (SCC) kwezinye izigaba zensimbi engagqwali.
● Izendlalelo Zokuhlukanisa: Umklamo wesisekelo kufanele ube nomgoqo ongokwenyama—njengendawo ye-neoprene enokuminyana okuphezulu, i-HDPE liner, noma i-bitumen-free mastic ekhethekile—phakathi kukakhonkolo kanye nengxenye engezansi yetangi.
2. Izixazululo Ezivamile Zesisekelo
A. I-Pedestal Ephakanyisiwe (Egcizelela Inhlanzeko)
Le modeli, evame ukusetshenziswa ezitshalweni zokudla nezamaphilisi, iphakanyisa lonke itangi nge-concrete pedestals noma imilenze yensimbi engagqwali.
● Inzuzo: Inikeza amandla aphelele okuhlanza ngaphansi kwethangi, ivimbele ukuqoqeka kodaka, amagciwane, noma i-biofilm.
● Inothi Lobunjiniyela: Kufanele yakhelwe ukuphatha imithwalo yokuzamazama komhlaba, njengoba isikhungo samandla siphakeme kakhulu kune-tank esekelwe ku-slab.
B. Udonga Oluyindilinga Lwe-Concrete Ngamanzi
EmataNgeni amakhulu aqondile, kusetshenziswa udonga oluyindilinga lwe-concrete oluqiniswe ngensimbi. Ithangi lihlezi phezu komalaka ohlanganisiwe, ongahlanganisi insimbi, futhi ongabi namakloride.
● Inzuzo: Kuyonga kakhulu kumadayamitha amakhulu ngenkathi kugcinwa ibanga elidingekayo ukusuka enhlabathini nasekhonkrithini.
● Inothi Lobunjiniyela: Ingaphezulu kodonga lwendandatho kufanele luqiniswe ngomthambeka (i-camber) kude nodonga lwethangi ukuvimbela ukuqoqana kwamanzi.
C. I-Slab-on-Grade (Nokuhlukaniswa)
Isetshenziselwa amathangi amancane noma lapho phansi kufanele kube munye nodonga lwesikhungo.
● Inzuzo: Kwandisa ukusetshenziswa kwesikhala sangaphansi.
● Inothi Lobunjiniyela: Idinga upende oluqinile lwe-epoxy noma i-polyurethane phezu kwekhonkrithi ukuze luvalwe, kanye "nesiketi" sensimbi engagqwalisiwe noma i-plinth ukuhlukanisa umphetho wethangi kubahlanza phansi nomswakama.
3. I-Matrix Yokuqhathanisa Yezobuchwepheshe
Ukukhetha uhlobo olufanele lwesisekelo kuncike ezidingweni zenhlanzeko kanye nosayizi wesitsha.
Uhlobo Lwesisekelo | Izinga Lenhlanzeko | Ukuphathwa Kokucindezeleka Okushisayo | Isicelo Esingcono Kakhulu |
I-Pedestal Ephakanyisiwe | Okungcono Kakhulu | Okuhle kakhulu (Ukuhamba Komoya) | Amalungiselelo Ephilisi/Okudla/Okokuphuza |
I-Concrete Ring Wall | Kulinganiselwe | Kuhle | Amakhemikhali/amanzi amakhulu |
I-Slab-on-Grade | Phezulu (ene-coating) | Kuhle | Amathangi amancane/aphakathi endlini |
I-Saddle Support | Phakathi | Kakhulu | Amathangi ensimbi engagqwali ayekwele |
4. Izinto Ezibalulekile Zobunjiniyela
Lapho kuklanywa lezi zisekelo, abobunjiniyela bomphakathi nabakhi bokwakha kumele baqinisekise:
● Isilinganiso Sokunweba Ngenxa Yokushisa: Insimbi engagqwali inesilinganiso esiphakeme sokunweba ngenxa yokushisa kune-carbon steel. Uma ithangi liboshwe ngokuqinile kakhulu esisekelweni, ukushintsha kokushisa kungadala ukugoba. Isisekelo kumele sivumele ukunweba okuncane okungaphandle.
● Ukubeka Okungenawo InsSimbi: Uma usebenzisa udonga oluyindilinga, impahla yokugcwalisa ngaphakathi kumele ingenazo izinhlayiya zensimbi noma usawoti, okungadala "ukugqwala" ngaphansi komhlaba phansi kwensimbi engagqwali.
● Ukuqedwa Kwendawo Engaphezulu: Ezinhlelweni zokuhlanzeka, phansi eduze kwesisekelo kumele kube nomthambeka ophuma uye endaweni yokudonsa amanzi. Akumele kube "nezindawo ezifile" lapho izinto zokuhlanza zingakwazi ukuqoqana eduze kwesisekelo sethangi.
5. Imibuzo Evame Ukubuzwa (FAQ)
Umbuzo: Ngidinga i-liner phakathi kwesisekelo nethangi lensimbi engagqwali?
A: Yebo. I-membrane yokuhlukanisa (njenge-HDPE geomembrane noma i-neoprene sheet) iyatuswa kakhulu. Isebenza njengendawo yokushelela ukuze kuvunyelwane nokunwebeka kwe-thermal futhi ivimbele ukuthintana okuqondile phakathi kwensimbi nomswakama we-concrete.
Q: Ngingasebenzisa i-rebar evamile ye-carbon steel esisekelweni ngaphansi kwethangi lensimbi engagqwalisiwe?
A: Yebo, uma nje i-concrete cover yanele futhi kukhona ungqimba oluhlukanisayo phakathi kwezinga elingezansi le-tank kanye nendawo ye-concrete. Insimbi engagqwalisiwe akumele ithinte ukuqinisa insimbi.
Q: Ngiyihlanza kanjani ngaphansi kwethangi lensimbi engagqwalisiwe eliphakanyisiwe?
A: Imiklamo ephakanyisiwe (ama-pedestal noma imilenze) yakhelwe ngokukhethekile ukuze ihlanjwe ngamanzi anomfutho ophezulu kanye nezinqubo ze-Clean-in-Place (CIP). Qinisekisa ukuthi uhlelo lokudonsa lwesikhungo sakho lwakhelwe ukubhekana nevolumu yamanzi adonsayo adaliwe ngesikhathi samajikijolo okuhlanza.
Izixazululo zokwakhiwa kwezisekelo zamathangi ensimbi engagqwali ziqhutshwa isidingo sokuhlanzeka nokuqina. Noma ngabe kusebenzisa i-pedestal ephakanyisiwe ukuze kucutshungulwe ngokwezempilo noma udonga oluyindilinga ukuze kugcinwe amakhemikhali asindayo, umgomo oyinhloko wobunjiniyela ukuhlukanisa insimbi engagqwali ezintweni ezingcolisa imvelo nezinto ezisetshenziswayo. Ukuqondiswa kochwepheshe kwezobunjiniyela bezindawo kanye nezakhiwo kubalulekile ukuqinisekisa ukuthi lezi zimpahla ezibalulekile zihlala zisebenza isikhathi esihloselwe sona.
Ngabe njengamanje uklama ukwakheka kwesikhungo sezempilo, futhi ungathanda isiqondiso esithile ezidingweni zokubopha ezizamazama komhlaba zamaphedestali ethangi lensimbi engagqwali ephakanyisiwe?
