Fiberglass Yakasimbiswa Polymer Bars
Detailed Sumo
Fiber yakasimbiswa composites (FRP) mumagariro einjiniya zvikumbiro mukukosha kwe "matambudziko ekugara uye mune mamwe akakosha mamiriro ekushanda kuti atambe huremu hwayo, simba repamusoro, anisotropic maitiro," akasanganiswa neyazvino nhanho yehunyanzvi hwekushandisa uye mamiriro emusika, nyanzvi dzeindasitiri. tenda kuti kushandiswa kwayo kunosarudza. Mu subway shield yekucheka kongiri chimiro, yakakwirira-giredhi migwagwa mitsetse uye mugero rutsigiro, kuramba kukukurwa kwemakemikari nemimwe minda kwakaratidza kuita kwakanakisa kwechikumbiro, zvakanyanya kugamuchirwa nechikamu chekuvaka.
Chigadzirwa Specification
Nominal madhayamita anotangira 10mm kusvika 36mm. Inokurudzirwa mazita madhayamita eGFRP mbariro i20mm, 22mm, 25mm, 28mm uye 32mm.

Application Technology
1. Geotechnical engineering neGFRP anchor support technology
Tunnel, materu uye mapurojekiti epasi pevhu achabatanidza geotechnical anchoring, anchoring anowanzo shandisa high tensile simba simbi seanchor rods, GFRP bhaa munzvimbo yakarebesa yakashata geological mamiriro ane yakanaka kusaita ngura, GFRP bhaa pachinzvimbo chesimbi anchor tsvimbo pasina chikonzero chekuora. , simba rakanyanya kusimba, huremu huremu uye nyore kugadzira, kutakura uye kuisa zvakanakira, parizvino, GFRP bar iri kuwedzera kushandiswa seancho. tsvimbo dze geotechnical projects. Parizvino, mabhawa eGFRP ari kushandiswa zvakanyanya uye zvakanyanya sematanda eanchor mune geotechnical engineering.
2. Self-inductive GFRP bar intelligent monitoring technology
Fiber grating sensors ine akawanda akasiyana mabhenefiti pamusoro pechinyakare simba sensors, senge yakapusa chimiro chemusoro unonzwa, diki size, huremu huremu, yakanaka kudzokorora, anti-electromagnetic kupindira, kunzwisiswa kwepamusoro, chimiro chakasiyana uye kugona kuiswa muGFRP bar. mukugadzira. LU-VE GFRP Smart Bar musanganiswa weLU-VE GFRP mabhawa uye faibha grating sensors, ine kusimba kwakasimba, yakanakisa dhirivha yekupona uye inonzwisa tsitsi yekuchinjisa maitiro, akakodzera einjiniya yehurumende uye mamwe minda, pamwe nekuvaka uye sevhisi pasi pehasha. mamiriro ezvakatipoteredza.
3. Shield cuttable kongiri yekusimbisa tekinoroji
Kuti uvhare kupindira kwemvura kana ivhu pasi pekuita kwekumanikidza kwemvura nekuda kwekubviswa kwesimbi yekusimbisa mukongiri mune subway yakavharirwa chimiro, kunze kwemadziro ekumisa mvura, vashandi vanofanirwa kuzadza imwe ivhu rakaoma kana kunyange plain kongiri. . Kushanda kwakadaro pasina mubvunzo kunowedzera kusimba kwevashandi uye nguva yekutenderera yekuchera pasi pevhu. Mhinduro ndeyekushandisa GFRP bar cage pachinzvimbo chesimbi, iyo inogona kushandiswa mune kongiri chimiro che subway end enclosure, kwete chete kutakura kutakura kunogona kuzadzisa zvinodiwa, asiwo nekuda kwekuti iyo GFRP bar kongiri chimiro chine mukana wekuti inogona kutemwa mumushini wenhovo (TBMs) ichipfuura neyakavharika, ichibvisa zvakanyanya kukosha kwevashandi kupinda nekubuda mumashaft anoshanda nguva zhinji, izvo zvinogona mhanyisa kukurumidza kwekuvaka uye kuchengeteka.
4. GFRP bar ETC lane application tekinoroji
Nzira dziripo dzeETC dziripo mukurasikirwa kweruzivo rwekupfuura, uye kunyange kudzokororwa kuderedzwa, kuvhiringidzwa kwemigwagwa yevavakidzani, kudzokororwa kurodha ruzivo rwekutengeserana uye kutadza kwekutengeserana, nezvimwewo, kushandiswa kweasina magineti uye asiri-conductive GFRP mabara pachinzvimbo chesimbi mugwara. inogona kuderedza chiitiko ichi.
5. GFRP bhaa inoenderera yakasimbiswa kongiri pavement
Inoramba ichisimbisa kongiri pavement (CRCP) ine kutyaira kwakagadzikana, yakakwirira kutakura simba, kusimba, kugadzirisa nyore uye zvimwe zvakakosha, kushandiswa kwegirazi fiber reinforcing bars (GFRP) pachinzvimbo chesimbi inoiswa kune ino dhizaini chimiro, zvese kukurira zvipingamupinyi zviri nyore. corrosion yesimbi, asiwo kuchengetedza zvakanakira zvekuramba zvakasimbiswa kongiri pavement, asi zvakare kuderedza kushushikana mukati meiyo pavement chimiro.
6. Kudonha uye yechando GFRP bar anti-CI kongiri yekushandisa tekinoroji
Nekuda kwechiitiko chinowanzoitika cheicing yemugwagwa munguva yechando, munyu de-icing ndeimwe yenzira ine hupfumi uye inoshanda, uye chloride ion ndiyo inonyanya kukonzera ngura yekusimbisa simbi mune yakasimbiswa kongiri pavement. Iko kushandiswa kweakanakisa corrosion kuramba kweGFRP mabara pachinzvimbo chesimbi, kunogona kuwedzera hupenyu hwepavhu.
7. GFRP bar marine concrete reinforcement teknolojia
Chloride corrosion yekusimbisa simbi ndiyo inonyanya kukosha inokanganisa kusimba kweakasimbiswa kongiri zvimiro mumapurojekiti ekumahombekombe. Iyo hombe-span girder-slab chimiro chinowanzo shandiswa mumateshi echiteshi, nekuda kwekuremerwa kwayo uye mutoro muhombe wainotakura, inoiswa pasi pekukotama nguva huru uye mauto ekugera mukati menguva yegirder refu uye parutsigiro, iyo kutendeuka kunoita kuti mitswe iite. Nekuda kwekuita kwemvura yegungwa, aya mabhawa ekusimbisa enzvimbo anogona kuomeswa munguva pfupi pfupi, zvichikonzera kudzikiswa kwesimba rekutakura rechimiro chese, izvo zvinokanganisa kushandiswa kwakajairwa kweiyo wharf kana kunyangwe kuitika kwetsaona dzekuchengetedza. .
Chiyero chekushandisa: seawall, chivakwa chemvura pamberi pemvura, dziva remvura, reef reef, chimiro chekupwanya kwemvura, chiteshi chinoyangarara.
etc.
8. Mamwe maapplication akakosha emabhawa eGFRP
(1) Anti-electromagnetic kupindira yakakosha application
Airport uye zvivakwa zvemauto anti-radar kupindira midziyo, inonzwisisika mauto ekuyedza zvivakwa, kongiri madziro, yehutano unit MRI michina, geomagnetic observatory, nuclear fusion zvivakwa, airport command tower, nezvimwewo, inogona kushandiswa pachinzvimbo chesimbi mbariro, mbariro dzemhangura, etc. GFRP mbariro sezvo kusimbisa zvinhu nokuda kongiri.
(2) Sandwich wall panel connectors
Iyo precast sandwich insulated wall panel inoumbwa nekongiri yemativi mapaneru uye insulating layer iri pakati. Chimiro chinotora iyo ichangoburwa OP-SW300 girazi fiber reinforced composite material (GFRP) zvinongedzo kuburikidza neiyo thermal insulation board kuti ibatanidze maviri kongiri eparutivi mapaneru pamwe chete, zvichiita kuti madziro ekudzivirira anopisa abvise zvachose mabhiriji anotonhora mukuvaka. Ichi chigadzirwa hachingo shandisa iyo isiri-yekupisa conductivity yeLU-VE GFRP tendons, asi zvakare inopa yakazara kutamba kune musanganiswa maitiro e sandwich wall.
