1. Ukuthuthukisa Ukusebenza Kokwakha kanye Nokwelula Impilo Yesevisi

Inhlanganisela ye-fiber-reinforced polymer (FRP) inezinto zokwakha ezihlaba umxhwele, ezinenani eliphakeme kakhulu lamandla nesisindo kunezinto zokwakha zendabuko. Lokhu kuthuthukisa umthamo wesakhiwo wokuthwala umthwalo ngenkathi kunciphisa isisindo saso sonke. Uma isetshenziselwa izakhiwo ezibanzi ezifana nezinsimbi zophahla noma amabhuloho, izingxenye ze-FRP zidinga izakhiwo ezimbalwa ezisekelayo, ezehlisa izindleko zesisekelo futhi zithuthukise ukusetshenziswa kwendawo.

Isibonelo, isakhiwo sophahla senkundla yezemidlalo enkulu eyenziwe ngezinhlanganisela ze-FRP sinesisindo esingama-30% esingaphansi kwesakhiwo sensimbi. Lokhu kunciphise umthwalo esakhiweni esikhulu futhi kwathuthukisa ukumelana nokugqwala, kusivikela ngokuphumelelayo endaweni enomswakama ngaphakathi kwendawo. Lokhu kwandise impilo yesevisi yebhilidi futhi kwehlisa nezindleko zokusilungisa zesikhathi eside.

 2. Ukuthuthukisa Izinqubo Zokwakha Ukuze Kuthuthukiswe Ukusebenza Kahle

Ikhono lokuzenzela nokukhiqizaIzinhlanganisela ze-FRPkumafomu e-modular kunciphisa kakhulu ukwakhiwa. Esilungiselelweni sefekthri, isikhunta esithuthukisiwe nemishini ezenzakalelayo ilawula ngokunembile inqubo yokubumba, iqinisekisa ikhwalithi ephezulu, izingxenye zokwakha ezinemba okuphezulu.

Ngezitayela zezakhiwo eziyinkimbinkimbi ezifana nedizayini yaseYurophu, izindlela zendabuko zidinga ukuqoshwa kwezandla nokufaka amatshe okuthatha isikhathi esiningi nokusebenza kanzima, okunemiphumela engahambisani. I-FRP, nokho, isebenzisa amasu okubumba aguquguqukayo kanye nemodeli ye-3D ukwenza isikhunta sezingxenye zokuhlobisa eziyinkimbinkimbi, okuvumela ukukhiqizwa okukhulu.

Emphakathini wokuhlala okunethezeka, ithimba lephrojekthi lisebenzisa amaphaneli okuhlobisa e-FRP ezindonga zangaphandle. La maphaneli enziwa efekthri abese athuthelwa endaweni ukuze ahlanganiswe. Uma kuqhathaniswa nokwakhiwa kwamatshe kanye nokuplastelwa kwendabuko, isikhathi sokwakha sehlisiwe sisuka ezinyangeni eziyisithupha saya kwezintathu, okuwukunyuka kokusebenza kahle okucishe kube ngama-50%. Amaphaneli futhi abe nemithungo efanayo kanye nezindawo ezibushelelezi, athuthukisa kakhulu ikhwalithi yesakhiwo nokukhanga kobuhle, futhi azuza ukunconywa okuphezulu kubahlali kanye nemakethe.

3. Ukushayela Intuthuko Esimeme kanye Nokuzijwayeza Izimiso Zokwakha Eziluhlaza

Izinhlanganisela ze-FRP zifaka isandla ekuthuthukisweni okusimeme embonini yezokwakha ngezinzuzo eziqinile zemvelo. Ukukhiqizwa kwezinto zendabuko njengensimbi nosimende kudla amandla. Insimbi idinga ukuncibilikiswa kwezinga lokushisa eliphezulu, okudla izinto zokubasa ezimbiwa phansi njengamalahle ne-coke futhi ikhiphe isikhutha. Ngokuphambene, ukukhiqizwa nokubunjwa kwezinhlanganisela ze-FRP kulula, kudinga amazinga okushisa aphansi namandla amancane. Izibalo zochwepheshe zibonisa ukuthi ukukhiqizwa kwe-FRP kusebenzisa amandla angaphansi kuka-60% kunensimbi, kunciphisa ukusetshenziswa kwezinsiza kanye nokukhishwa kwekhabhoni futhi kukhuthaze ukuthuthukiswa kokuluhlaza okuvela emthonjeni.

Izinhlanganisela ze-FRP nazo zinenzuzo ehlukile ekusetshenzisweni kabusha. Nakuba izinto zokwakha zendabuko kunzima ukuzisebenzisa kabusha, i-FRP ingahlakazwa futhi iphinde icutshungulwe kusetshenziswa izinqubo ezikhethekile zokugaywa kabusha. Abalulamaimicu yengilaziingasetshenziswa kabusha ukukhiqiza imikhiqizo emisha eyinhlanganisela, idale umnotho oyindilinga osebenza kahle. Inkampani enkulu yokukhiqiza eyinhlanganisela isungule uhlelo lokugaywa kabusha lapho izinto ezilahliwe ze-FRP zichotshozwa futhi zihlolwe ukuze kwakhiwe amafayibha agaywe kabusha, abese esetshenziselwa ukukhiqiza amaphaneli okwakha nezinto zokuhlobisa. Lokhu kunciphisa ukuthembela emithonjeni emisha futhi kunciphisa umthwalo wemvelo wokulahlwa.

Ukusebenza kwemvelo kwe-FRP ezinhlelweni zokwakha nakho kuyaphawuleka. Ekwakhiweni kwesakhiwo samahhovisi esonga amandla, i-FRP yasetshenziselwa izindonga, kuhlanganiswe nomklamo wokushisa oshisayo osebenza kahle kakhulu. Lokhu kunciphise kakhulu ukusetshenziswa kwamandla okushisa nokupholisa kwesakhiwo. Izibalo zibonisa ukuthi ukusetshenziswa kwamandla kwalesi sakhiwo bekungaphansi ngo-20% kunezakhiwo zendabuko, kunciphisa kakhulu ukuthembela kwaso kumafutha ezinto ezimbiwa phansi njengamalahle negesi yemvelo kanye nokunciphisa ukukhishwa kwekhabhoni. I-microstructure eyingqayizivele ye-FRP ihlinzeka ngokufaka ukufudumala okuhle kakhulu nempilo ende yesevisi, futhi ukusetshenziswa kwayo kunciphisa udoti wokwakha okhiqizwa ukulungiswa nokulungiswa kwesakhiwo.

Njengoba imithethonqubo yezemvelo iba namandla, izinzuzo ezisimeme zeIzinhlanganisela ze-FRPembonini yezokwakha ziya ngokuya zigqama. Ukwamukelwa okusabalele kwalokhu kwaziswa kumaphrojekthi ahlukahlukene—kusukela ezakhiweni zokuhlala kuye kwezentengiselwano, kusukela ezikhungweni zomphakathi kuya ezimbonini zezimboni—kunikeza isisombululo esisebenzayo soshintsho oluluhlaza embonini. Njengoba izinhlelo zokugaywa kabusha zithuthuka kanye nobuchwepheshe obuhlobene buthuthuka, i-FRP izodlala indima enkulu nakakhulu emkhakheni wezokwakha, iqinise izici zayo ezinekhabhoni ephansi kanye nezici ezivumelana nemvelo futhi ibe negalelo ekuzuzweni kwezinjongo zentuthuko esimeme.
