Mabhawa ePolymer Akasimbiswa neFiberglass
Nhanganyaya Yakadzama
Zvishandiso zvefiber zvinosimbiswa (FRP) mukushandiswa kweinjiniya yezvivakwa mukukosha kwe "matambudziko ekugara kwenguva refu uye mune mamwe mamiriro ekushanda akakosha kuti zviite sezvisina kureruka, simba rakawanda, hunhu hweanisotropic," pamwe chete nedanho razvino rekushandisa tekinoroji nemamiriro emusika, nyanzvi dzeindasitiri dzinotenda kuti kushandiswa kwayo kunosarudza. Mukuchengetedza chivakwa chekongiri pasi pevhu, migwagwa mikuru yepamusoro uye rutsigiro rwematangi, kuramba kukanganiswa nemakemikari uye mimwe minda kwaratidza kushanda kwakanaka kwekushandisa, uye kwave kugamuchirwa zvakanyanya nechikamu chekuvaka.

Tekinoroji yekushandisa
1. Uinjiniya hweGeotechnical netekinoroji yekutsigira GFRP anchor
Mapurojekiti emugero, ekutsvedza uye epasi pevhu achasanganisira kunamatira kwenzvimbo dzepasi pevhu, kunamatira kunowanzo shandisa simbi yakasimba yekunamatira sematanda ekunamatira, GFRP bar mumamiriro ezvinhu asina kunaka kwenguva refu ine simba rakanaka rekudzivirira ngura, GFRP bar panzvimbo pematanda ekunamatira esimbi pasina chikonzero chekurapa ngura, simba guru rekunamatira, huremu hushoma uye nyore kugadzira, mabhenefiti ekutakura nekuisa, pari zvino, GFRP bar iri kushandiswa zvakanyanya sematanda ekunamatira kumapurojekiti ezvepasi pevhu. Parizvino, matanda eGFRP ari kushandiswa zvakanyanya sematanda ekunamatira muinjiniya yezvepasi pevhu.
2. Tekinoroji yekutarisa yeGFRP bar inozvigadzira yega
Ma sensor ekugadzira fiber ane mabhenefiti akawanda akasiyana pane ma sensor emagetsi echinyakare, akadai sechimiro chiri nyore chemusoro wekuona, saizi diki, huremu hwakareruka, kugona kudzokororwa zvakanaka, anti-electromagnetic interference, high sensitivity, variable shape uye kugona kuiswa muGFRP bar mukugadzirwa. LU-VE GFRP Smart Bar isanganiswa yeLU-VE GFRP bars uye fiber grating sensors, ine kugara kwenguva refu, mwero wakanaka wekurarama kwekushandisa uye hunhu hwekutumira strain, hwakakodzera mainjiniya ehurumende nedzimwe nzvimbo, pamwe nekuvaka uye sevhisi mumamiriro ezvinhu akaoma.
3. Tekinoroji yekusimbisa kongiri inochekwa nesimbi
Kuti mvura kana ivhu zvisapinde pasi pesimba remvura nekuda kwekubviswa kwesimbi mukongiri muchivako chepasi pevhu, kunze kwemadziro anovhara mvura, vashandi vanofanira kuzadza ivhu rakakora kana kongiri isina chinhu. Kushanda kwakadaro pasina mubvunzo kunowedzera simba revashandi uye nguva yekuchera tunnel pasi pevhu. Mhinduro ndeyekushandisa GFRP bar cage panzvimbo pekeji yesimbi, iyo inogona kushandiswa muchivako chekongiri chepasi pevhu, kwete chete simba rekutakura rinogona kusangana nezvinodiwa, asiwo nekuda kwekuti chimiro chekongiri cheGFRP bar chine mukana wekuti chinogona kuchekwa mumuchina wekudzivirira (TBMs) unopfuura nepachivako, zvichibvisa zvakanyanya kudiwa kwevashandi kupinda nekubuda mumashaft ekushanda nguva nenguva, izvo zvinogona kukurumidzisa kumhanya kwekuvaka uye kuchengetedzeka.
4. Tekinoroji yekushandisa nzira yeGFRP bar ETC
Nzira dziripo dzeETC dziripo mukurasikirwa neruzivo rwekufamba, uye kunyange kuderedzwa kwakadzokororwa, kukanganiswa kwemigwagwa iri pedyo, kudzokororwa kweruzivo rwekutengeserana uye kukundikana kwekutengeserana, nezvimwewo, kushandiswa kwemabhawa eGFRP asina magineti uye asina kufambisa mhepo panzvimbo pesimbi mumigwagwa kunogona kunonotsa chiitiko ichi.
5. GFRP bar inoenderera mberi nekugadzira kongiri yakasimbiswa
Nzira yekufamba nepasi pekongiri yakasimbiswa nguva dzose (CRCP) ine kutyaira kwakasununguka, ine simba rekutakura zvinhu zvakawanda, inogara kwenguva refu, iri nyore kugadzirisa uye zvimwe zvakanakira zvakakosha, kushandisa girazi fiber rekusimbisa simbi (GFRP) pachinzvimbo chesimbi inoshandiswa panzira iyi, zvese zviri zviviri kukunda zvakanakira ngura iri nyore yesimbi, asiwo kuchengetedza zvakanakira nzira yekufamba nepasi pekongiri yakasimbiswa nguva dzose, asiwo kuderedza kushushikana mukati menzira yekufamba nepasi.
6. Tekinoroji yekushandisa kongiri yeGFRP bar anti-CI mumatsutso nechando
Nekuda kwechiitiko chinowanzoitika chekuisa icing mumugwagwa munguva yechando, kubvisa icing munyu ndeimwe yenzira dzinodhura uye dzinoshanda, uye maion echloride ndiwo anonyanya kukonzera ngura yesimbi inosimbisa simbi mumugwagwa wekongiri wakasimbiswa. Kushandisa simbi dzeGFRP panzvimbo pesimbi kunogona kuwedzera hupenyu hwemugwagwa.
7. Tekinoroji yekusimbisa kongiri yegungwa yeGFRP bar
Kuora kwesimbi inosimbiswa ne chloride ndicho chinhu chinonyanya kukanganisa kugara kwenguva refu kwezvivakwa zvekongiri yakasimbiswa mumapurojekiti ekunze. Chimiro chegirder-slab chakakura chinowanzoshandiswa muchiteshi chengarava, nekuda kwekurema kwacho uye mutoro mukuru wachinotakura, chinokotamira zvakanyanya uye simba rekuchekwa mukati megirder refu uye pakutsigira, izvo zvinoita kuti matombo abude. Nekuda kwekushanda kwemvura yegungwa, aya masimbi ekusimbisa emunharaunda anogona ngura munguva pfupi, zvichikonzera kudzikira kwesimba rekutakura chivakwa chose, izvo zvinokanganisa kushandiswa kwechikepe kana kutoitika kwetsaona dzekuchengetedza.
Chimiro chekushandisa: madziro egungwa, chimiro chekuvaka chegungwa, dziva rekurima, matombo ekugadzira, chimiro chemvura, chiteshi chinoyangarara
nezvimwewo.
8. Mamwe mashandisirwo akakosha eGFRP bars
(1) Kushandiswa kwakakosha kweAnti-electromagnetic interference
Nzvimbo dzendege nedzemauto, zvishandiso zvinodzivirira kukanganiswa kweradar, nzvimbo dzekuyedza michina yemauto, madziro ekongiri, michina yeMRI yekuchengetedza hutano, nzvimbo yekuongorora yemagetsi, zvivakwa zvenyukireya, shongwe dzekuraira dzenhandare yendege, nezvimwewo, zvinogona kushandiswa pachinzvimbo chesimbi, simbi dzemhangura, nezvimwewo. GFRP bars sezvinhu zvinosimbisa kongiri.
(2) Zvinobatanidza mapaneru emadziro esandwich
Panera remadziro rakagadziriswa nesandwich rakaumbwa nemapanera maviri emativi ekongiri uye layer inodziisa pakati. Chimiro ichi chinoshandisa zvisungo zvitsva zveOP-SW300 glass fiber reinforced composite material (GFRP) kuburikidza nebhodhi rekudziisa thermal kuti zvibatanidze mapanera maviri emativi ekongiri pamwe chete, zvichiita kuti madziro ekudziisa thermal abvise zvachose mabhiriji anotonhora mukuvaka. Chigadzirwa ichi hachingoshandisi chete LU-VE GFRP tendons isingashandise thermal conductivity, asiwo chinopa mukana wakazara wekusanganiswa kwemadziro esandwich.
