Imigoqo eqinisiwe ye-fiberglass
Isingeniso Esinemininingwane
Ama-Composites aqinisiwe wefayibha (i-FRP) kwizicelo zobunjiniyela zomphakathi ngokubaluleka kwe- "Esakhiwo Ukuqina Kwezimo Zokudlala Ezikhethekile zokudlala ezingasindi, amandla aphezulu, ochwepheshe bezimboni bakholelwa ukuthi uhlelo lokusebenza lukhetha. Esivikelweni sesitimela ukusika isakhiwo sokhonkolo, imithambeka ephezulu yemigwaqo ephakeme kanye nokusekelwa komhubhe, ukumelana nokuguguleka kwamakhemikhali nezinye izinkambu kukhombise ukusebenza kwesicelo okuhle kakhulu, okwengeziwe nokwamukelwa yiyunithi yokwakha.
Ukucaciswa komkhiqizo
Amadayimitha angamagama aqala kusuka ku-10mm kuya ku-36mm. Kunconywe ama-radinal ama-radinal amabha we-GFRP angama-20mm, angama-22mm, 25mm, 28mm no-32mm.

Ubuchwepheshe bohlelo lokusebenza
1
Umhubhe, ama-slope kanye namaphrojekthi angaphansi komhlaba azobandakanya i-geotechnical anchrorical, ama-anchlang ajwayele ukusebenzisa insimbi ephezulu ye-anchor, i-gfrer bar ezimweni zokugqwala, okulula ukukhiqiza, njengamanje, ibha ye-GfRP iya ngokuya isetshenziswa njengezinduku ze-anchor zamaphrojekthi we-geotechnical. Njengamanje, imigoqo ye-GFRP isetshenziswa ngokwengeziwe njengezinduku ze-anchor ku-Geotechnical Engineering.

Izinzwa ze-fiber grating zinezinzuzo eziningi ezihlukile zezinzwa zendabuko zendabuko, njengesakhiwo esilula sekhanda elizwakalayo, usayizi omncane, ukuphindaphindwa okuhle, ukuzwela okuphezulu, ukwakheka okuguqukayo, ukwakheka okuguqukayo kanye nekhono lokufakwa kubha ye-GFRP inqubo yokukhiqiza. I-Lu-Ve Gfrep Smart Bar iyinhlanganisela ye-Lu-Ve Gffp Bar kanye nezinzwa ezinhle ze-fiber, ngokuqina okuhle, izinga lokudlulisa izinto ezingcono kakhulu kanye nezinye izinkambu, kanye nenkonzo kanye nenkonzo ngaphansi kwezimo zemvelo ezibucayi.

Ukuze uvimbele ukungena kwamanzi noma inhlabathi ngaphansi kwesenzo sokucindezelwa kwamanzi ngenxa yokususwa kwensimbi kukhonkolo ekwakhiweni okubekiwe, ngaphandle kodonga olubekiwe lwamanzi, abasebenzi kufanele bagcwalise inhlabathi eminyene noma ukhonkolo ocacile. Ukusebenza okunjalo ngokungangabazeki kwandisa amandla abasebenzi abasebenzi kanye nesikhathi sokujikeleza komjikelezo osendaweni engaphansi komhlaba. Isixazululo ukusebenzisa i-GFRP BAR CAGE esikhundleni sekheji lensimbi, elingasetshenziswa esakhiweni sikakhonkolo sendawo yokungena ngaphakathi, kodwa futhi ngenxa yokuthi i-GfRS Prekcrete SAHLE inenzuzo yokungena ngaphakathi, okungasheshisa ijubane lokwakha kanye nokuphepha.
4. I-GfRP BAR ETC Lane Technology
Imigwaqo ekhona ekhona ikhona ekulahlekelweni kwemininingwane yendawo, kanye nokuncishiswa okuphindaphindiwe, ukuphazamiseka komgwaqo okungumakhelwane, Ukulayishwa okuphindaphindiwe kwemigwaqo, njll.
I-5. I-GfRP Bar eqhubekayo eqhubekayo yokuqina kokhonkolo
I-ConcRECE EQINISEKILEYO YOKUGCINA (CRCP) Ngokushayela okunethezekile, umthamo ophakeme, ohlala isikhathi eside, ukulungiswa okulula nezinye izinzuzo ezigcizelelwa yi-cavelos yensimbi, kodwa futhi nokugcina izingcindezi zesakhiwo esinqunyelwe ngokuqhubekayo.

Ngenxa yento evamile ye-icing yomgwaqo ebusika, usawoti de-icing kungenye yezindlela ezengeziwe ezomnotho nezisebenzayo, futhi i-chloride ion iyimicimbi esemqoka yokugqwala kwensimbi ekhonkolo eqinisiwe. Ukusetshenziswa kokumelana okuhle kakhulu kokugqwala kwemigoqo ye-GFRS esikhundleni sensimbi, kungakhulisa impilo yendlela.

Ukugqwala kwe-chloride kokuqiniswa kwensimbi kuyisici esibaluleke kakhulu esithinta ukuqina kwezinhlaka zokhonkolo eziqinisiwe kumaphrojekthi aphesheya kwezilwandle. Isakhiwo esikhulu se-girder-slab esivame ukusetshenziswa emaphethelweni emikhundla, ngenxa yokuzizwa komthwalo wakhe kanye nomthwalo omkhulu wokugoba kanye namabutho amakhulu okugoba kanye namabutho we-shear endaweni ende ye-longitudinal. Ngenxa yesenzo samanzi olwandle, le migoqo yokuqinisa okwenziwe yasendaweni ingalungiswa ngesikhathi esifushane kakhulu, okuholela ekunciphiseni umthamo we-eark wesakhiwo esiphelele, esithinta ukuvela kwezingozi ezijwayelekile.
Isilinganiso sohlelo lokusebenza: Ukwakhiwa kwasolwandle, ukwakhiwa kwamanzi, ichibi le-aquaculture, i-artificial reef, isakhiwo sekhefu lamanzi, idokodo elintantayo
njll.
8. Ezinye izinhlelo ezikhethekile zemigoqo ye-GFRP
(1) Isicelo esikhethekile se-anti-electromagnetic application
Isikhumulo sezindiza kanye namadivayisi wezempi alwa-radar infection amadivayisi, izindonga zokhonkolo ezibucayi, izindonga zekhonkrithi, imishini yokunakekelwa kwempilo, imigoqo ye-geomagnetic, ingasetshenziswa imigoqo yokuqinisa ukhonkolo.
(2) Izixhumi ze-Sandwich Wall Panel
I-sandwich yesandwich efakwe eWandwich eyakhiwe ngamaphaneli amabini amabili ekhonkolo kanye nesendlalelo sokufaka esikalini. Isakhiwo samukela i-OP-SPROFE esanda kwethulwa i-OP-SP300 Glass fiber eqinisiwe izixhumi ze-Composite Material (GFRP) ngokusebenzisa i-Thermal Inflation Board ukuxhumanisa amaphaneli amabini amabili ekhonkolo ndawonye, okwenza udonga lokufakelwa okushisayo luqede ngokuphelele amabhuloho abandayo ekwakhiweni. Lo mkhiqizo awugcini nje ngokusebenzisa izimbotshana ezingezona ezishisayo zama-ge-ve ama-GfRS Terrons, kepha futhi unikeza ukudlala okugcwele emphumeleni wokuhlanganisa odongeni lwe-sandwich.
