Fiberglass Yakasimbiswa Polymer Bars
Detailed Sumo
Fiber reinforced composites (FRP) mumashandisirwo einjiniya mukukosha kwe "zvinetso zvekugara kwenguva refu uye mune mamwe mamiriro akakosha ekushanda kuti atambe huremu hwayo, simba repamusoro, anisotropic maitiro," akasanganiswa nehuwandu hwazvino hwehunyanzvi hwekushandisa uye mamiriro emusika, nyanzvi dzeindasitiri dzinotenda kuti mashandisiro ayo anosarudza. 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 yakakwirira tensile simba simbi seanchor rods, GFRP bhaa munzvimbo yakarebesa isina kunaka geological mamiriro ane yakanaka kusaonda, GFRP bhaa pachinzvimbo chesimbi anchor tsvimbo pasina kudiwa kwekuora, kusimba kwesimba, huremu huremu uye nyore kugadzira, kutakura kunowedzera, GF iripo uye bhenekeri rinowedzera kugadzirwa, kutakura uye bhenekeri. 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 dhizaini yemusoro unonzwa, diki saizi, uremu huremu, yakanaka kudzokorora, anti-electromagnetic kupindira, kunzwisiswa kwepamusoro, kuchinjika chimiro uye kugona kuiswa muGFRP bar mukugadzira maitiro. LU-VE GFRP Smart Bar musanganiswa weLU-VE GFRP mabara uye faibha grating sensors, ine kusimba kwakasimba, yakanakisa dhizaini yekupona uye inocherekedza dhizaini yekuchinjisa hunhu, inokodzera civil engineering uye mamwe minda, pamwe nekuvaka uye sevhisi pasi pemamiriro ekunze akaomarara.
3. Shield cuttable kongiri yekusimbisa tekinoroji
Kuti uvhare kupindira kwemvura kana ivhu pasi pechiito chekumanikidza kwemvura nekuda kwekubviswa kwesimbi yekusimbisa mukongiri mune subway yakavharirwa chimiro, kunze kwemadziro ekumisa mvura, vashandi vanofanirwa kuzadza imwe dense ivhu 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 mukongiri yekongiri yekuvharirwa kwepasi pevhu, kwete chete kutakura simba kunogona kuzadzisa zvinodiwa, asiwo nekuda kwekuti iyo GFRP bar kongiri chimiro chine mukana wekuti inogona kutemwa mumushini wenhoo (TBMs) ichipfuura yakavharirwa, ichibvisa zvakanyanya kushaikwa kwevashandi. mhanyisa kukurumidza kwekuvaka uye kuchengeteka.
4. GFRP bar ETC lane application tekinoroji
Iripo ETC nzira dziripo mukurasikirwa kwemashoko endima, uye kunyange kudzokororwa kuderedzwa, kukanganiswa kwemigwagwa yevavakidzani, kudzokororwa kurodha ruzivo rwekutengeserana uye kukundikana kwekutengeserana, nezvimwewo, kushandiswa kwemagineti uye kwete-conductive GFRP mbariro panzvimbo yesimbi mumigwagwa inogona kuderedza chiitiko ichi.
5. GFRP bhaa inoenderera yakasimbiswa kongiri pavement
Inoramba ichisimbisa kongiri pavement (CRCP) ine kutyaira kwakagadzikana, yakakwira kutakura simba, yakasimba, kugadzirisa nyore uye zvimwe zvakakosha, kushandiswa kwegirazi fiber reinforcing bars (GFRP) pachinzvimbo chesimbi inoiswa kune ino dhizaini chimiro, zvese kukurira zvipingamupinyi zvekuora nyore kwesimbi, asiwo kuchengetedza zvakanakira zvekuramba uchisimbisa mukati meiyo kongiri inosimbisa, asi zvakare kuderedza kusimba kwekongiri.
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 yakakura-span girder-slab chimiro chinowanzo shandiswa mumateshi echiteshi, nekuda kwehuremu hwayo uye mutoro wakakura wainotakura, inoiswa pasi penguva dzakakura dzekukotama uye mauto ekugera mukati mehurefu hwegirder uye parutsigiro, izvo zvinozoita 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 mauto zvivako anti-radar kupindira midziyo, mauto echiuto kuedza midziyo, kongiri madziro, utano utano MRI midziyo, geomagnetic observatory, nyukireya fusion zvivakwa, airport command tower, etc., inogona kushandiswa panzvimbo simbi mbariro, mhangura mbariro, etc. GFRP mbariro sechinhu chinosimbisa kwekongiri.
(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.
