Iindawo Zokuqaqamba Ezihlala Zihleli ZeeTreyi Zeentambo Zentsimbi Kwiindawo Ezinzima Zokusebenza
Amaqela okwakha sele efumene iingxaki ezingenakuphephekaiitreyi zekhebula zesinyithikwiindawo ezinomhlwa ophezulu. Iifama zomoya eziselunxwemeni, iipayiphu zikamasipala eziselunxwemeni, izityalo zeekhemikhali kunye nezikhululo zokucoca amdaka zihlala zichatshazelwa yinkungu yetyuwa, umsi osekelwe kwi-asidi kunye nokufuma okuphezulu.
Ezi meko zinzima zokusebenza zitshabalalisa izakhiwo zentsimbi ezirhangqiweyo ngokukhawuleza. Iirekhodi zokugcinwa kwendawo ezivela kwiiprojekthi zomoya ezili-12 zaseMzantsi-mpuma Asia zibonisa ukuba umhlwa ubonakala kwiitreyi zekhebula zentsimbi eziqhelekileyo kwiminyaka emine kuphela yokusebenza.
Ukugqwala okungalawulwayo kunciphisa amandla okuthwala izinto, kuguqula iifreyimu zetreyi kwaye kukrwele ubushushu bentambo yangaphandle ngokuhamba kwexesha. Okubaluleke ngakumbi kukuba, iitreyi zentsimbi eziqhubayo ziya kusasaza iimpazamo zesekethe xa kuphuma ukuvuza kwentambo, nto leyo ebangela umngcipheko wokhuseleko rhoqo kubasebenzi abasebenza ngaphambili kunye nabasebenzi bokulungisa.
Uninzi lwabanini beeprojekthi ngaphambili babekhetha iitreyi zentsimbi ukuze bafumane iindleko zokuthenga eziphantsi. Sekunjalo abazange bayikhathalele imirhumo yokulungisa efihlakeleyo eqhubekayo eqokelelwe ngexesha lokusebenza kweprojekthi ixesha elide.
Izibalo zeendleko zoshishino zibonisa ukuba iitreyi zekhebula zesinyithi zifuna ukususwa komhlwa kobuchwephesha kunye nokupeyintwa ngokutsha kokubola rhoqo emva kweenyanga ezili-18 kwiindawo ezinobungozi. Ngaphakathi komjikelo weprojekthi weminyaka engama-25, iindleko zokugcinwa kunye nokutshintshwa zizonke zinokuphinda kabini utyalo-mali lokuqala lwezinto zokwakha, zidale umthwalo wemali ongeyomfuneko kwiiprojekthi zeziseko zophuhliso zexesha elide.
Amandla Angundoqo Awenza Iitreyi Zekhebula ze-FRP Zibe Yindlela Engcono
Zenziwe nge-one-piece integral molding ene-fiberglass mesh kunye ne-anti-corrosion vinyl resin, iitreyi zekhebula ze-FRP zisombulula iingxaki zezinto zesinyithi ngokusisiseko.
Ngokungafaniyo neetreyi zentsimbi ezixhomekeke kwiingubo zomphezulu ukukhusela ukugqwala, izinto ezikrwada ze-FRP azina-asidi, i-alkali, inkungu yetyuwa kunye neegesi ezininzi zeekhemikhali zoshishino. Imveliso egqityiweyo ayifuni unyango olongezelelweyo lokulwa nomhlwa kwaye ayidingi kugcinwa rhoqo emva kokufakwa.
Uvavanyo lobunjineli basentsimini lubonisa ukuba iitreyi zekhebula ze-FRP ezifanelekileyo zinokusebenza ngokuzinzileyo iminyaka engama-28 ukuya kwengama-30 kwiindawo ezixineneyo, ubomi benkonzo obuphindwe kathathu kuneemveliso zesinyithi eziqhelekileyo ezishushu eziditywayo.
Ezinye iingenelo ezimbini ezisebenzayo zizuze ukuqatshelwa ngokubanzi ngabakhi behlabathi. Okokuqala, ipropati yayo engeyiyo ehambisa umbane ithintela uthumelo lwamandla ngexesha leengozi zokuvuza kweentambo, ithintela iimpazamo zesekethe kwiindawo ezincinci kwaye ithintela ukucima kombane okukhulu.
Okwesibini, iitreyi zekhebula ze-FRP zilula kakhulu, zinobunzima obuyi-1/3 kuphela yeetreyi zentsimbi ezinomgangatho ofanayo wokuthwala umthwalo. Uyilo olulula lunciphisa kakhulu ubunzima bokufakelwa kwindawo ephakamileyo kwaye lunciphisa ixesha lokwakhiwa kweprojekthi iyonke malunga ne-25%.
Imfuno Ekhulayo Yemarike Eqhutywa Lulwakhiwo Lwamandla Amatsha Lwehlabathi
Imfuno yehlabathi yeetreyi zekhebula ze-FRP ibangelwa ikakhulu ngamandla omoya akhula ngokukhawuleza olwandle, ukuhlaziywa kwemizi-mveliso kunye neeprojekthi zendlela yemibhobho kamasipala.
Ukwakhiwa kwefama yomoya engaphandle kolwandle kuluhlu lwezona zinto zifunekayo kakhulu. Ukuze kufezekiswe iinjongo zokungathathi cala kwekhabhoni, iYurophu, iMpuma Asia kunye neMzantsi-mpuma Asia zikhawulezisa ulwakhiwo olukhulu lweziseko zomoya engaphandle kolwandle. Indawo engqongileyo yaselwandle erhabaxa kakhulu yenza iitreyi zekhebula ze-FRP zibe yinto eyimfuneko yokuncedisa kwiintambo kuzo zonke iinkqubo zombane zaselwandle.
Ngaphandle koko, iiprojekthi zokuhlaziya iipaki zemizi-mveliso ezindala eYurophu naseMntla Melika ziyaphelisa iitreyi zentsimbi ezigugileyo ezigugileyo ngokwamaqela. Zonke izityalo ezisandula ukwakhiwa ezisebenzisa iikhemikhali kunye nokucoca amdaka zidwelise iitreyi zentambo ze-FRP njengezixhobo ezixhasayo ezisemgangathweni kwimizobo yokwakha esemthethweni.
Imingeni ekhoyo kuShishino kunye neendlela zoPhuhliso lwexesha elizayo
Nangona iingenelo zokusebenza ezibalaseleyo, iitreyi zekhebula ze-FRP zisajongene nemiqobo ethintela ukungena ngakumbi kwimarike.
Ixabiso eliphezulu lokuthenga kwangaphambili xa lithelekiswa neetreyi zentsimbi lisengumqobo omkhulu, ingakumbi kwiiprojekthi zikamasipala ezincinci ezinemijikelo yenkonzo emfutshane. Okwangoku, abavelisi abangalawulwayo abakumgangatho ophantsi banciphisa iindleko zezinto eziluhlaza ngokunciphisa umxholo wefiberglass kunye nokusebenzisa i-resin ephantsi.
Ezi mveliso ze-FRP ezingezizo ezilungileyo azinawo amandla okumelana nempembelelo kwaye azinawo amandla okusebenza afanelekileyo okubamba umlilo, nto leyo eyonakalisa udumo lwalo lonke eli shishini. Ukongeza, ukungabikho kwemigangatho yemveliso yehlabathi edibeneyo kubangela ukungalingani okuncinci kweenkcukacha ngexesha lokubhida kobunjineli obungaphaya kwemida.
Abahlalutyi beshishini banombono onethemba wexesha elide wophuhliso lwetreyi yekhebula ye-FRP. Njengoko abanini beprojekthi abaninzi bebeka phambili iindleko zomjikelo wobomi bonke kuneendleko zokwakha zexesha elinye, inzuzo yezoqoqosho yeemveliso ze-FRP ezingenalondolozo iya kuba yinto ephawulekayo.
Abavelisi abaphambili bakwaphucula iifomyula zezinto eziluhlaza ukuze banciphise umsantsa wamaxabiso phakathi kweetreyi zekhebula ze-FRP kunye nezentsimbi. Kwixesha elizayo, iitreyi zekhebula ze-FRP ezikrelekrele ezixhotyiswe ngee-sensors zokujonga ubushushu kunye nokuvuza ngexesha langempela ziya kuqaliswa ukuze zihambelane neemfuno zokwakha igridi ekrelekrele.
Kwiminyaka emihlanu ezayo, iitreyi zekhebula ze-FRP ziya kuphuma kwiimeko ezinzima kwaye zisetyenziswe kakhulu kubunjineli bombane bangaphakathi nangaphandle. Ezi zinto ziya kuqhubeka nokubumba ngokutsha imakethi yolawulo lweekhebula zehlabathi ebisoloko ilawulwa ziimveliso zesinyithi.
