Iteknoloji yesicelo
1. Ubunjineli be-Geotechnical ngeteknoloji ye-GFRP ye-anchor inkxaso
Itonela, ithambeka kunye neeprojekthi zikaloliwe eziphantsi komhlaba ziya kubandakanya i-anchoring ye-geotechnical, i-anchoring isoloko isebenzisa intsimbi ephezulu yokuqina njengeentonga ze-ankile, ibha ye-GFRP kwiimeko ezimahlwempu zexesha elide zinokumelana ne-corrosion, ibha ye-GFRP endaweni yeentonga ze-ankile yentsimbi ngaphandle kwemfuneko yonyango lomhlwa, amandla aphezulu okuqina, ubunzima obulula kunye ne-advanteji eyongezelelekileyo ye-GF njengoko ikhoyo kwaye isetyenziswa ngokulula, ukufakwa kwe-GF, ukufakwa kunye nokufakwa lula. iirodi zeeprojekthi ze-geotechnical. Okwangoku, imivalo ye-GFRP isetyenziswa ngakumbi nangakumbi njengeentonga ze-ankile kubunjineli be-geotechnical.
2. Itekhnoloji yokubeka iliso ekrelekrele ibha ye-GFRP yokuzingenisa
I-Fiber grating sensors ineenzuzo ezininzi ezikhethekileyo ngaphezu kwee-sensor zamandla zendabuko, ezifana nesakhiwo esilula sentloko yokuva, ubungakanani obuncinci, ubunzima bokukhanya, ukuphindaphinda okulungileyo, ukuphazamiseka kwe-anti-electromagnetic, uvakalelo oluphezulu, ukumila okuguquguqukayo kunye nokukwazi ukufakwa kwi-bar ye-GFRP kwinkqubo yokuvelisa. I-LU-VE GFRP Smart Bar yindibaniselwano ye-LU-VE GFRP imivalo kunye ne-fiber grating sensors, ehlala ixesha elide, izinga eliphezulu lokusinda kunye neempawu ezithintekayo zokudluliselwa koxinzelelo, ezifanelekileyo kubunjineli boluntu kunye nezinye iindawo, kunye nokwakhiwa kunye nenkonzo phantsi kweemeko ezibuhlungu zokusingqongileyo.
3. Ithekhinoloji yokuqinisa ikhonkrithi yeShield cuttable
Ukuze uthintele ukungena kwamanzi okanye umhlaba phantsi kwesenzo soxinzelelo lwamanzi ngenxa yokususwa okwenziweyo kokuqiniswa kwentsimbi kwikhonkrithi kwisakhiwo sokuvalwa kwendlela, ngaphandle kodonga lokumisa amanzi, abasebenzi kufuneka bazalise umhlaba oxineneyo okanye nokuba ikhonkrithi ecacileyo. Umsebenzi onjalo ngokungathandabuzekiyo unyusa ubunzulu bomsebenzi wabasebenzi kunye nexesha lomjikelo wokwembiwa kwetonela engaphantsi komhlaba. Isisombululo kukusebenzisa i-GFRP bar yekheji endaweni yentsimbi yentsimbi, enokuthi isetyenziswe kwisakhiwo sekhonkrithi ye-subway end enclosure, kungekuphela nje umthamo wokuthwala unokuhlangabezana neemfuno, kodwa nangenxa yokuba i-GFRP bar isakhiwo sekhonkrithi sinenzuzo yokuba sinokunqunyulwa kumatshini wekhaka (TBMs) ukunqumla indawo ebiyelweyo, ukuphelisa kakhulu imfuneko yokusebenza kunye nabasebenzi. ukukhawulezisa isantya sokwakha kunye nokhuseleko.
4. Itekhnoloji yesicelo se-GFRP bar ETC
Imizila ye-ETC ekhoyo ikhona ekulahlekeni kolwazi lokuhamba, kunye nokuncitshiswa okuphindaphindiweyo, ukuphazamiseka kwendlela engummelwane, ukulayishwa ngokuphindaphindiweyo kolwazi lwentengiselwano kunye nokungaphumeleli kwentengiselwano, njl., Ukusetyenziswa kwemivalo ye-GFRP engeyiyo-magnetic kunye ne-non-conductive endaweni yentsimbi kwi-pavement inokunciphisa le nto.
5. Ibha ye-GFRP eqhubekayo yepavumente yekhonkrithi eyomeleziweyo
Ipavumente eyomeleziweyo ngokuqhubekayo (CRCP) ngokuqhuba kakuhle, umthamo ophezulu wokuthwala, ixesha elide, ukugcinwa lula kunye nezinye iingenelo ezibalulekileyo, ukusetyenziswa kwemivalo yeglasi yokuqinisa ifayibha (GFRP) endaweni yentsimbi esetyenzisiweyo kolu lwakhiwo lwendlela, zombini ukoyisa ukungalungi kwentsimbi elula, kodwa nokugcina iingenelo zokuqhubeka koxinzelelo ngaphakathi koxinzelelo oluqhubekayo, kodwa kwakhona ukuncipha koxinzelelo lwepawunti.
6. Ukuwa kunye nobusika i-GFRP ibha ye-anti-CI ye-concrete application technology
Ngenxa yento eqhelekileyo yendlela ebusika, i-salt de-icing yenye yeendlela zoqoqosho kunye neyona ndlela isebenzayo, kwaye i-chloride ion yizona zinto zibangela ukubola kwensimbi yokuqinisa kwi-pavement yekhonkrithi eqinisiweyo. Ukusetyenziswa kokumelana okugqwesileyo kwe-corrosion kwimivalo ye-GFRP endaweni yentsimbi, kunokunyusa ubomi be-pavement.
7. I-GFRP ibha yokuqinisa iteknoloji yokuqinisa ikhonkrithi yaselwandle
I-Chloride corrosion of steel reinforcement yeyona nto ibalulekileyo echaphazela ukuqina kwezakhiwo zekonkrithi ezomeleziweyo kwiiprojekthi ezikude nonxweme. Isakhiwo esikhulu se-span girder-slab esihlala sisetyenziswa kwiitheminali zechweba, ngenxa yobunzima baso kunye nomthwalo omkhulu esiwuthweleyo, sixhomekeke kwixesha elikhulu lokugoba kunye nemikhosi yokucheba ngexesha le-longitudinal girder nakwinkxaso, ebangela ukuba iintanda ziphuhlise. Ngenxa yesenzo samanzi olwandle, le mivalo yokomelezwa kwendawo inokugqweswa ngexesha elifutshane kakhulu, okukhokelela ekunciphiseni umthamo wokuthwala wesakhiwo esipheleleyo, esichaphazela ukusetyenziswa okuqhelekileyo kwe-wharf okanye nokubakho kweengozi zokhuseleko.
Umda wesicelo: udonga lolwandle, ulwakhiwo lolwakhiwo lwasemanzini, ichibi lasemanzini, ulwalwa olwenziweyo, ulwakhiwo lokuphumla kwamanzi, idokhi edadayo.
njl.
8. Ezinye izicelo ezizodwa zeebha ze-GFRP
(1)Anti-electromagnetic uphazamiseko isicelo esikhethekileyo
Isikhululo seenqwelomoya kunye nezixhobo zomkhosi izixhobo ezichasene nokuphazamiseka kwe-radar, izixhobo zomkhosi ezibuthathaka zokuvavanya izixhobo, iindonga zekhonkrithi, iyunithi yokhathalelo lwempilo izixhobo ze-MRI, i-geomagnetic observatory, izakhiwo ze-nyukliya ze-fusion, iinqaba zomyalelo wesikhululo seenqwelomoya, njl., zingasetyenziswa endaweni yeentsimbi zentsimbi, imivalo yobhedu, njl.
(2) Izihlanganisi zepaneli yodonga lweSandwich
I-sandwich ye-precast insulated panel yodonga yenziwe ngamacandelo amabini ekhonkrithi kunye ne-insulating layer embindini. Isakhiwo samkela i-OP-SW300 ifayibha yeglasi esanda kwaziswa ifayibha eyomeleziweyo (GFRP) izihlanganisi ngokusebenzisa ibhodi yokugquma i-thermal ukudibanisa iiphaneli ezimbini zecala lekhonkrithi kunye, okwenza udonga lokufakelwa kwe-thermal luphelise ngokupheleleyo iibhulorho ezibandayo kulwakhiwo. Le mveliso ayisebenzisi kuphela i-non-thermal conductivity ye-LU-VE GFRP i-tendon, kodwa inika umdlalo opheleleyo kwisiphumo sokudibanisa kodonga lwesandwich.
