Amabha e-Polymer aqiniswe nge-Fiberglass
Isingeniso Esiningiliziwe
Izinhlanganisela eziqiniswe ngefayibha (i-FRP) ekusetshenzisweni kobunjiniyela bezezakhiwo ngokubaluleka "kwezinkinga zokuqina kwesakhiwo kanye nakwezinye izimo zokusebenza ezikhethekile ukuze kudlale izici zayo ezilula, ezinamandla aphezulu, ze-anisotropic," kuhlanganiswe nezinga lamanje lobuchwepheshe bokusetshenziswa kanye nezimo zemakethe, ochwepheshe bemboni bakholelwa ukuthi ukusetshenziswa kwayo kuyakhetha. Esivikelweni sesitimela esingaphansi komhlaba ukusika isakhiwo sekhonkrithi, imithambeka yomgwaqo ephezulu kanye nokusekelwa kwemihubhe, ukumelana nokuguguleka kwamakhemikhali kanye neminye imikhakha kubonise ukusebenza okuhle kakhulu kokusetshenziswa, okwamukelwa kakhulu yiyunithi yokwakha.
Ukucaciswa Komkhiqizo
Ububanzi obujwayelekile busukela ku-10mm kuya ku-36mm. Ububanzi obujwayelekile obunconywayo bemigoqo ye-GFRP yi-20mm, 22mm, 25mm, 28mm kanye ne-32mm.

Ubuchwepheshe Bokusebenza
1. Ubunjiniyela be-Geotechnical obusebenzisa ubuchwepheshe bokusekela i-GFRP
Amaphrojekthi e-tunnel, slope kanye ne-subway azobandakanya ukunamathisela kwe-geotechnical, ukunamathisela kuvame ukusebenzisa insimbi enamandla okudonswa njengezintambo zokukhonkotha, ibha ye-GFRP ezimweni ze-geological ezingezinhle zesikhathi eside inokumelana okuhle kokugqwala, ibha ye-GFRP esikhundleni sezinduku zokukhonkotha zensimbi ezingenasidingo sokwelashwa kokugqwala, amandla aphezulu okudonswa, isisindo esincane futhi okulula ukukhiqizwa, izinzuzo zokuhamba nokufakwa, okwamanje, ibha ye-GFRP isetshenziswa kakhulu njengezinduku zokukhonkotha kumaphrojekthi we-geotechnical. Njengamanje, izinduku ze-GFRP zisetshenziswa kakhulu njengezinduku zokukhonkotha kubunjiniyela be-geotechnical.
2. Ubuchwepheshe bokuqapha obuhlakaniphile bebha ye-GFRP obuzithuthukisayo
Izinzwa ze-fiber grating zinezinzuzo eziningi ezihlukile kunezinzwa zamandla zendabuko, njengesakhiwo esilula sekhanda lokuzwa, usayizi omncane, isisindo esincane, ukuphindaphindeka okuhle, ukuphazamiseka kwe-anti-electromagnetic, ukuzwela okuphezulu, ukuma okuguquguqukayo kanye nekhono lokufakwa kubha ye-GFRP enqubweni yokukhiqiza. I-LU-VE GFRP Smart Bar iyinhlanganisela yezinzwa ze-LU-VE GFRP kanye nezinzwa ze-fiber grating, ezinokuqina okuhle, izinga lokusinda elihle kakhulu lokufakwa kanye nezici zokudlulisa ukucindezeleka okubucayi, ezifanele ubunjiniyela bezokwakha kanye neminye imikhakha, kanye nokwakhiwa kanye nensizakalo ngaphansi kwezimo zemvelo ezinzima.
3. Ubuchwepheshe bokuqinisa ukhonkolo obusikiwe obungasikwa
Ukuze kuvinjwe ukungena kwamanzi noma inhlabathi ngaphansi kwesenzo sokucindezela kwamanzi ngenxa yokususwa kokwenziwa kokuqinisa insimbi kukhonkolo esakhiweni sendawo ebiyelwe ngaphansi komhlaba, ngaphandle kodonga oluvimba amanzi, abasebenzi kumele bagcwalise inhlabathi eminyene noma ngisho nekhonkolo engenalutho. Ukusebenza okunjalo ngokungangabazeki kwandisa amandla abasebenzi kanye nesikhathi sokujikeleza kokumba imigudu engaphansi komhlaba. Isixazululo ukusebenzisa ikheji lebha le-GFRP esikhundleni sekheji lensimbi, elingasetshenziswa esakhiweni sekhonkolo sendawo ebiyelwe ngaphansi komhlaba, hhayi nje kuphela amandla okuthwala angahlangabezana nezidingo, kodwa futhi ngenxa yokuthi isakhiwo sekhonkolo sebha le-GFRP sinenzuzo yokuthi singasikwa emshinini wesihlangu (TBMs) odlula endaweni ebiyelwe, okususa kakhulu isidingo sokuba abasebenzi bangene futhi baphume emithonjeni yokusebenza njalo, okungasheshisa isivinini sokwakha kanye nokuphepha.
4. Ubuchwepheshe bokusebenzisa umzila webha ye-GFRP ETC
Imizila ye-ETC ekhona ikhona ekulahlekelweni kolwazi lokudlula, ngisho nokuncishiswa okuphindaphindiwe, ukuphazamiseka komgwaqo oseduze, ukulayishwa okuphindaphindiwe kolwazi lokuthengiselana kanye nokwehluleka kokuthengiselana, njll., ukusetshenziswa kwemigoqo ye-GFRP engeyona i-magnetic kanye ne-non-conductive esikhundleni sensimbi emgwaqweni kunganciphisa lesi simo.
5. Ibha ye-GFRP eqinisiwe eqhubekayo
Indlela yokuhamba ngokhonkolo eqiniswe njalo (i-CRCP) enokushayela okukhululekile, amandla aphezulu okuthwala, ukuqina, ukulungiswa okulula kanye nezinye izinzuzo ezibalulekile, ukusetshenziswa kwezinsimbi zokuqinisa ingilazi (i-GFRP) esikhundleni sensimbi esetshenziswa kulesi sakhiwo sendlela yokuhamba ngokhonkolo, kokubili ukunqoba ubuthakathaka bokugqwala kalula kwensimbi, kodwa futhi nokugcina izinzuzo zendlela yokuhamba ngokhonkolo eqiniswe njalo, kodwa futhi nokunciphisa ukucindezeleka ngaphakathi kwesakhiwo sendlela yokuhamba ngokhonkolo.
6. Ubuchwepheshe bokusebenzisa ukhonkolo be-GFRP bar anti-CI ekwindla nasebusika
Ngenxa yento evamile yokwenziwa kwe-icing emgwaqweni ebusika, ukususa i-salt icing kungenye yezindlela ezingabizi kakhulu neziphumelelayo, kanti ama-ion e-chloride ayimbangela eyinhloko yokugqwala kwensimbi yokuqinisa emgwaqweni wekhonkrithi oqinisiwe. Ukusetshenziswa kokumelana okuhle kakhulu nokugqwala kwezinsimbi ze-GFRP esikhundleni sensimbi, kungandisa impilo yendlela.
7. Ubuchwepheshe bokuqinisa ukhonkolo wasolwandle ngebha ye-GFRP
Ukugqwala kwe-chloride kokuqinisa insimbi kuyisici esibaluleke kakhulu esithinta ukuqina kwezakhiwo zekhonkrithi eziqinisiwe kumaphrojekthi asogwini. Isakhiwo se-girder-slab esikhulu esivame ukusetshenziswa ezindaweni zokubeka imikhumbi, ngenxa yesisindo saso kanye nomthwalo omkhulu esiwuthwalayo, sibhekana nezikhathi ezinkulu zokugoba kanye namandla okusika ngesikhathi se-girder ende kanye nokusekelwa, okubangela ukuthi kukhule imifantu. Ngenxa yesenzo samanzi olwandle, lezi zingodo zokuqinisa zendawo zingagqwala ngesikhathi esifushane kakhulu, okuholela ekunciphiseni kwamandla okuthwala isakhiwo sonke, okuthinta ukusetshenziswa okuvamile kwechweba noma ngisho nokuvela kwezingozi zokuphepha.
Ububanzi besicelo: udonga lwasolwandle, isakhiwo sesakhiwo esiseceleni kolwandle, ichibi lezolimo zasemanzini, udonga lwamatshe okwenziwa, isakhiwo sekhefu lamanzi, idoko elintantayo
njll.
8. Ezinye izinhlelo zokusebenza ezikhethekile zamabha e-GFRP
(1) Isicelo esikhethekile sokuphazamiseka kwe-anti-electromagnetic
Izikhungo zezindiza nezempi, amadivayisi okulwa nokuphazamiseka kwe-radar, izindawo zokuhlola imishini yezempi ebucayi, izindonga zekhonkrithi, imishini ye-MRI yeyunithi yokunakekelwa kwempilo, indawo yokuhlola i-geomagnetic, izakhiwo ze-nuclear fusion, imibhoshongo yomyalo wesikhumulo sezindiza, njll., ingasetshenziswa esikhundleni semigoqo yensimbi, imigoqo yethusi, njll. Imigoqo ye-GFRP njengento yokuqinisa ikhonkrithi.
(2) Izixhumi zephaneli yodonga yesandwich
Iphaneli yodonga olufakwe i-sandwich efakwe kusengaphambili yakhiwe ngamaphaneli amabili aseceleni ekhonkrithi kanye nesendlalelo sokuvikela phakathi nendawo. Isakhiwo samukela izixhumi ze-OP-SW300 glass fiber reinforced composite material (GFRP) ezisanda kwethulwa ngebhodi lokuvikela ukushisa ukuze kuxhunywe amaphaneli amabili aseceleni ekhonkrithi ndawonye, okwenza udonga lokuvikela ukushisa luqede ngokuphelele amabhuloho abandayo ekwakhiweni. Lo mkhiqizo awusebenzisi nje kuphela ukuhanjiswa kwemisipha ye-LU-VE GFRP okungewona ukushisa, kodwa futhi unikeza ukusebenza okugcwele komphumela wokuhlanganiswa kodonga lwe-sandwich.
