Iteknoloji yesicelo
1. Ubunjineli be-Geotechnical ngeteknoloji ye-GFRP ye-anchor inkxaso
Itonela, i-slope kunye neeprojekthi ze-subway ziya kubandakanya i-anchoring ye-geotechnical, i-anchoring isoloko isebenzisa intsimbi ephezulu yokuqina njengeentonga ze-ankile, ibha ye-GFRP kwixesha elide leemeko zejoloji ezihlwempuzekileyo zinokuxhathisa okuhle kokubola, ibha ye-GFRP endaweni yeentsimbi ze-anchor zentsimbi ngaphandle kwemfuneko yonyango lomhlwa. Amandla aphezulu, ubunzima obulula kunye nokulula ukwenza, ukuthutha kunye nokufakwa kwezinto ezilungileyo, okwangoku, ibha ye-GFRP isetyenziswa kakhulu njenge-ankile. 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
Abenzi boluvo be-Fiber grating banezinto ezininzi eziluncedo ezikhethekileyo ngaphezulu kwezinzwa zamandla emveli, ezinje ngesakhiwo esilula sentloko yokuva, ubungakanani obuncinci, ubunzima bokukhanya, ukuphindaphindwa okuhle, ukuphazamiseka kwe-anti-electromagnetic, ubuntununtunu obuphezulu, imilo eguquguqukayo kunye nokukwazi ukufakwa kwibar ye-GFRP. kwinkqubo yemveliso. 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 zokudluliselwa koxinzelelo olubuthathaka, olulungele ubunjineli boluntu kunye nezinye iindawo, kunye nokwakhiwa kunye nenkonzo phantsi kobunzima. iimeko zokusingqongileyo.
3. Ikhaka leteknoloji yokuqinisa ikhonkrithi
Ukuze uthintele ukungena kwamanzi okanye umhlaba phantsi kwesenzo soxinzelelo lwamanzi ngenxa yokususwa okwenziweyo kokuqinisa intsimbi kwikhonkrithi kwisakhiwo sokuvalwa kwendlela, ngaphandle kodonga lokumisa amanzi, abasebenzi kufuneka bazalise umhlaba oshinyeneyo okanye nokuba ikhonkrithi ecacileyo. . Umsebenzi onjalo ngokungathandabuzekiyo unyusa ukuqina kwabasebenzi 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 ukuthwala umthamo onokuhlangabezana neemfuno, kodwa nangenxa yokuba i-GFRP bar isakhiwo sekhonkrithi sinakho inzuzo yokuba inokusikwa kumatshini wekhaka (TBMs) enqumla indawo ebiyelweyo, isusa kakhulu isidingo sabasebenzi sokungena nokuphuma rhoqo kwiishafu zokusebenza, ezinokuthi ukukhawulezisa isantya sokwakha kunye nokhuseleko.
4. Itekhnoloji yesicelo se-GFRP bar ETC
Imizila ekhoyo ye-ETC ikhona ekulahlekeni kolwazi lokudlula, kunye nokuncitshiswa okuphindaphindiweyo, ukuphazamiseka kwendlela engummelwane, ukulayishwa ngokuphindaphindiweyo kolwazi lwentengiselwano kunye nokusilela kwentengiselwano, njl., Ukusetyenziswa kwemivalo ye-GFRP engeyiyo-magnetic kunye ne-non-conductive endaweni yentsimbi kwi-pavement. inokucothisa le nto.
5. Ibha ye-GFRP eqhubekayo yepavumente yekhonkrithi eyomeleziweyo
Ipavumente eyomeleziweyo ngokuqhubekayo (CRCP) ngokuqhuba ngokukhululekileyo, umthamo ophezulu wokuthwala, ixesha elide, ukugcinwa lula kunye nezinye iingenelo ezibalulekileyo, ukusetyenziswa kweglasi yeglasi yokuqinisa imivalo (GFRP) endaweni yentsimbi esetyenzisiweyo kolu lwakhiwo lwendlela, zombini ukoyisa ukungalungi kokulula. i-corrosion yensimbi, kodwa kunye nokugcina iingenelo ze-pavement yekhonkrithi eyomeleziweyo ngokuqhubekayo, kodwa nokunciphisa uxinzelelo ngaphakathi kwesakhiwo se-pavement.
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. Ulwakhiwo lwe-slab-slab-span enkulu ehlala isetyenziswa kwiitheminali zezibuko, ngenxa yobunzima baso kunye nomthwalo omkhulu esiwuthweleyo, siphantsi kwamathuba amakhulu okugoba kunye nemikhosi yokucheba kwisithuba sebhanti yelongitudinal nakwinkxaso, ethi ukujika kubangela ukuba kubekho iintanda. Ngenxa yesenzo samanzi olwandle, ezi zivalo zokuqinisa zasekuhlaleni zinokugqweswa ngexesha elifutshane kakhulu, okukhokelela ekunciphiseni umthamo wokuthwala wesakhiwo ngokubanzi, esichaphazela ukusetyenziswa okuqhelekileyo kwe-wharf okanye ukwenzeka 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 zovavanyo, iindonga zekhonkrithi, iyunithi yokhathalelo lwempilo izixhobo ze-MRI, i-geomagnetic observatory, izakhiwo zokudityaniswa kwenyukliya, iinqaba zomyalelo wesikhululo seenqwelomoya, njl., zingasetyenziswa endaweni yeentsimbi zentsimbi, imivalo yobhedu, njl. Imivalo ye-GFRP njengento yokuqinisa ikhonkrithi.
(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.
