Itekhnoloji yesicelo
1. Ubunjineli beJiotechnical obusebenzisa itekhnoloji yenkxaso ye-ankile ye-GFRP
Iiprojekthi zeTunnel, iSlope kunye neSubway ziya kubandakanya ukubethelela i-geotechnical, ukubethelela kudla ngokusebenzisa intsimbi enamandla okutsalwa njengeentonga ze-anchor, iibha ze-GFRP kwiimeko ezimbi zejoloji ezihlala ixesha elide zinokuxhathisa ukugqwala okuhle, iibha ze-GFRP endaweni yeentonga zentsimbi ezingenasidingo sonyango lokugqwala, amandla aphezulu okutsalwa, ubunzima obulula kwaye kulula ukubenza, iingenelo zothutho kunye nokufakelwa, okwangoku, iibha ze-GFRP zisetyenziswa ngakumbi njengeentonga ze-anchor kwiiprojekthi zejoloji. Okwangoku, iibha ze-GFRP zisetyenziswa ngakumbi njengeentonga ze-anchor kubunjineli bejoloji.
2. Itekhnoloji yokubeka esweni ekrelekrele ye-GFRP bar ezenzekelayo
Izinzwa ze-fiber grating zineengenelo ezininzi ezikhethekileyo kunezinzwa zamandla zemveli, ezifana nolwakhiwo olulula lwentloko yokuva, ubungakanani obuncinci, ubunzima obulula, ukuphindaphindeka okuhle, ukuphazamiseka kwe-anti-electromagnetic, uvakalelo oluphezulu, imilo eguquguqukayo kunye nokukwazi ukufakwa kwibha ye-GFRP kwinkqubo yemveliso. I-LU-VE GFRP Smart Bar yindibaniselwano yeebha ze-LU-VE GFRP kunye nezinzwa ze-fiber grating, ezinokuqina okuhle, izinga elihle lokusinda ekusetyenzisweni kunye neempawu zokudluliselwa koxinzelelo olunobuthathaka, ezifanelekileyo kubunjineli bokwakha nakwamanye amasimi, kunye nokwakhiwa kunye nenkonzo phantsi kweemeko ezinzima zokusingqongileyo.
3. Itekhnoloji yokuqinisa ikhonkrithi enokusikwa ekhayeni
Ukuze kuthintelwe ukungena kwamanzi okanye umhlaba phantsi kwesenzo soxinzelelo lwamanzi ngenxa yokususwa kokwenziwa kwesinyithi kwikhonkrithi kwisakhiwo se-subway enclosure, ngaphandle kodonga oluvala amanzi, abasebenzi kufuneka bazalise umhlaba oxineneyo okanye ikhonkrithi ecacileyo. Olu hlobo lokusebenza ngokungathandabuzekiyo luyandisa amandla abasebenzi kunye nexesha lokujikeleza kokumba imigudu engaphantsi komhlaba. Isisombululo kukusebenzisa i-GFRP bar cage endaweni ye-steel cage, engasetyenziswa kwisakhiwo sekhonkrithi se-subway end enclosure, kungekuphela nje amandla okuthwala anokuhlangabezana neemfuno, kodwa kwanangenxa yokuba isakhiwo sekhonkrithi ye-GFRP bar sinenzuzo yokuba sinokusikwa kumatshini we-shield (TBMs) odlula kwi-enclosure, nto leyo esusa kakhulu imfuneko yokuba abasebenzi bangene bephuma kwi-shafts zokusebenza rhoqo, nto leyo enokukhawulezisa isantya sokwakha kunye nokhuseleko.
4. Itekhnoloji yesicelo sendlela ye-GFRP bar ETC
Iindlela ze-ETC ezikhoyo zikhona ekulahlekelweni kolwazi lokudlula, kwanokutsalwa okuphindaphindiweyo, ukuphazamiseka kwendlela ekufutshane, ukulayishwa okuphindaphindiweyo kolwazi lwentengiselwano kunye nokungaphumeleli kwentengiselwano, njl.njl., ukusetyenziswa kweebha ze-GFRP ezingezizo zemagnethi nezingezizo eziqhuba umbane endaweni yentsimbi kwindlela engaphantsi komhlaba kunokulibazisa le meko.
5. I-GFRP bar eqhubekayo eqinisiweyo yendlela yekhonkrithi
Indlela yokuhamba ngentsimbi eqinisiweyo rhoqo (CRCP) eqhuba kakuhle, inomthamo ophezulu wokuthwala, ihlala ixesha elide, kulula ukuyilungisa kunye nezinye iingenelo ezibalulekileyo, ukusetyenziswa kweebha zokuqinisa ifayibha yeglasi (GFRP) endaweni yentsimbi esetyenziswa kolu lwakhiwo lwendlela, zombini ukoyisa iingxaki zokubola kwentsimbi ngokulula, kodwa nokugcina iingenelo zendlela yokuhamba ngentsimbi eqinisiweyo rhoqo, kodwa nokunciphisa uxinzelelo ngaphakathi kwesakhiwo sendlela.
6. Itekhnoloji yesicelo sekhonkrithi ye-GFRP bar ekwindla nasebusika
Ngenxa yento eqhelekileyo yokugquma i-ayisi endleleni ebusika, ukususa i-salt de-icing yenye yeendlela ezingabizi kakhulu nezisebenzayo, kwaye ii-ion ze-chloride zezona zinto ziphambili zokugquma kwentsimbi eqinisayo kwindlela eqinisiweyo yekhonkrithi. Ukusetyenziswa kokumelana okuhle kokugquma kweebhari ze-GFRP endaweni yentsimbi, kunokwandisa ubomi bendlela.
7. Itekhnoloji yokuqinisa ikhonkrithi yolwandle yebha ye-GFRP
Ukubola kwe-chloride yokuqinisa intsimbi yeyona nto iphambili echaphazela ukuqina kwezakhiwo zekhonkrithi eziqinisiweyo kwiiprojekthi zaselunxwemeni. Isakhiwo se-girder-slab esikhulu esisetyenziswa rhoqo kwiindawo zokubeka izibuko, ngenxa yobunzima baso kunye nomthwalo omkhulu esiwuthwalayo, siphantsi kwamaxesha amakhulu okugoba kunye namandla okucheba kwisithuba se-girder ende nakwinkxaso, nto leyo ebangela ukuba kubekho imingxunya. Ngenxa yesenzo samanzi olwandle, ezi bar zokuqinisa zasekuhlaleni zinokubola ngexesha elifutshane kakhulu, nto leyo ebangela ukuncipha kwamandla okuthwala kwesakhiwo siphela, nto leyo echaphazela ukusetyenziswa okuqhelekileyo kwechweba okanye nokuba kwenzeke iingozi zokhuseleko.
Ububanzi besicelo: udonga lolwandle, isakhiwo sesakhiwo esisemanzini, ichibi lezolimo zasemanzini, ulwalwa lokwenziwa, isakhiwo sokuqhekeka kwamanzi, idokhi edadayo
njl. njl.
8. Ezinye izicelo ezikhethekileyo zeebha ze-GFRP
(1) Isicelo esikhethekileyo sokuphazamiseka kwe-anti-electromagnetic
Izixhobo zokuthintela ukuphazamisana ne-radar kwizikhululo zeenqwelo-moya nezomkhosi, izixhobo zokuvavanya izixhobo zomkhosi ezibuthathaka, iindonga zekhonkrithi, izixhobo ze-MRI zeyunithi yokhathalelo lwempilo, indawo yokujonga i-geomagnetic, izakhiwo ze-nuclear fusion, ii-towers zomyalelo wesikhululo seenqwelo-moya, njl.njl., zingasetyenziswa endaweni yeebha zentsimbi, iibha zekopolo, njl.njl.
