Chiyambi Chatsatanetsatane
Ma fiber reinforced composites (FRP) mu ntchito zauinjiniya wa zomangamanga chifukwa cha "mavuto olimba a kapangidwe kake komanso m'mikhalidwe ina yapadera yogwirira ntchito kuti igwire ntchito mopepuka, mwamphamvu kwambiri, komanso makhalidwe ake a anisotropic," kuphatikiza ndi mulingo wamakono waukadaulo wogwiritsira ntchito komanso momwe msika ulili, akatswiri amakampani amakhulupirira kuti kugwiritsa ntchito kwake ndikosankha. Mu chitetezo cha sitima yapansi panthaka chodula kapangidwe ka konkire, malo otsetsereka apamwamba kwambiri komanso chithandizo cha ngalande, kukana kukokoloka kwa mankhwala ndi madera ena kwawonetsa magwiridwe antchito abwino kwambiri, ndipo kwavomerezedwa kwambiri ndi gulu lomanga.
Mafotokozedwe a Zamalonda
Ma dayamita odziwika bwino amayambira pa 10mm mpaka 36mm. Ma dayamita odziwika bwino a mipiringidzo ya GFRP ndi 20mm, 22mm, 25mm, 28mm ndi 32mm.

Zofunika: Zofunikira zina ziyenera kutsatira zomwe zili mu muyezo wa JG/T406-2013 “Glass Fiber Reinforced Plast for Civil Engineering”

Ukadaulo Wogwiritsa Ntchito
1. Uinjiniya wa Geotechnical ndi ukadaulo wothandizira wa GFRP nangula
Mapulojekiti a ngalande, malo otsetsereka ndi sitima yapansi panthaka adzaphatikizapo kuyika zitsulo za geotechnical, kuyika zitsulo nthawi zambiri kumagwiritsa ntchito chitsulo champhamvu kwambiri ngati ndodo za nangula, bala la GFRP m'malo mwa mikhalidwe yoipa ya geology nthawi yayitali limakhala ndi kukana dzimbiri, bala la GFRP m'malo mwa ndodo za nangula zachitsulo popanda chifukwa chothandizira dzimbiri, mphamvu yayikulu yoyika zitsulo, kulemera kopepuka komanso kosavuta kupanga, ubwino woyendera ndi kukhazikitsa, pakadali pano, bala la GFRP likugwiritsidwa ntchito kwambiri ngati ndodo za nangula pamapulojekiti a geotechnical. Pakadali pano, mipiringidzo ya GFRP ikugwiritsidwa ntchito kwambiri ngati ndodo za nangula mu uinjiniya wa geotechnical.
2. Ukadaulo wodziwunikira wanzeru wa GFRP bar wodzipangira wekha
Ma sensor olumikizira ulusi ali ndi ubwino wambiri kuposa ma sensor achikhalidwe, monga kapangidwe kosavuta ka mutu womvera, kukula kochepa, kulemera kopepuka, kubwerezabwereza bwino, kusokoneza kwa ma electromagnetic, kukhudzidwa kwambiri, mawonekedwe osinthika komanso kuthekera koyikidwa mu bala la GFRP popanga. LU-VE GFRP Smart Bar ndi kuphatikiza kwa mipiringidzo ya LU-VE GFRP ndi ma sensor olumikizira ulusi, okhala ndi kulimba kwabwino, kupulumuka bwino kwambiri komanso mawonekedwe osavuta kusamutsa mphamvu, oyenera mainjiniya ndi madera ena, komanso zomangamanga ndi ntchito pansi pa nyengo zovuta zachilengedwe.

3. Ukadaulo wolimbitsa konkire wodulidwa ndi chishango
Pofuna kuletsa kulowa kwa madzi kapena nthaka chifukwa cha mphamvu ya madzi chifukwa chochotsa chitsulo cholimbitsa mu konkire m'nyumba yosungiramo zinthu zapansi panthaka, kunja kwa khoma loletsa madzi, ogwira ntchito ayenera kudzaza dothi lolimba kapena konkire wamba. Mosakayikira, ntchito yotereyi imawonjezera mphamvu ya ogwira ntchito komanso nthawi yozungulira yofukula ngalande zapansi panthaka. Yankho lake ndikugwiritsa ntchito khola la GFRP m'malo mwa khola lachitsulo, lomwe lingagwiritsidwe ntchito mu kapangidwe ka konkire ka khola la pansi panthaka, osati mphamvu yokha yonyamulira yomwe ingakwaniritse zofunikira, komanso chifukwa chakuti kapangidwe ka konkire la GFRP m'mbali mwake kali ndi ubwino woti kakhoza kudulidwa mu makina oteteza (TBMs) omwe amadutsa m'khola, zomwe zimachotsa kwambiri kufunika kwa ogwira ntchito kulowa ndi kutuluka m'ma shaft ogwirira ntchito pafupipafupi, zomwe zingathandize kufulumizitsa liwiro la ntchito yomanga ndi chitetezo.
4. Ukadaulo wa GFRP bar ETC lane application
Misewu ya ETC yomwe ilipo ilipo chifukwa cha kutayika kwa chidziwitso cha njira, komanso ngakhale kuchotsedwa mobwerezabwereza, kusokoneza misewu yapafupi, kukweza mobwerezabwereza chidziwitso cha malonda ndi kulephera kwa malonda, ndi zina zotero, kugwiritsa ntchito mipiringidzo ya GFRP yopanda maginito komanso yosayendetsa magetsi m'malo mwa chitsulo m'misewu kungachedwetse vutoli.
5. Mzere wa konkire wokhazikika wa GFRP
Njira yoyendetsera konkire yolimbikitsidwa mosalekeza (CRCP) yokhala ndi kuyendetsa bwino, mphamvu zonyamula katundu zambiri, yolimba, yosavutikira kukonza komanso zabwino zina zofunika, kugwiritsa ntchito mipiringidzo yolimbitsa ulusi wagalasi (GFRP) m'malo mwa chitsulo chomwe chimagwiritsidwa ntchito panjira iyi, zonse ziwiri kuti zithetse mavuto a dzimbiri mosavuta, komanso kuti zisunge ubwino wa njira yoyendetsera konkire yolimbikitsidwa mosalekeza, komanso kuchepetsa kupsinjika mkati mwa njira yoyendetsera.
6. Ukadaulo wa GFRP bar anti-CI wogwiritsa ntchito konkriti nthawi ya autumn ndi yozizira
Chifukwa cha vuto lofala la ayisikilimu pamsewu m'nyengo yozizira, kuchotsa ayisikilimu ya mchere ndi njira imodzi yotsika mtengo komanso yothandiza, ndipo ma ayoni a chloride ndi omwe amachititsa kuti chitsulo cholimbitsa chizizirike m'misewu ya konkire yolimbikitsidwa chizizirike. Kugwiritsa ntchito mipiringidzo ya GFRP m'malo mwa chitsulo kungathandize kuti msewu ukhale wolimba komanso wautali.
7. Ukadaulo wolimbitsa konkire wa m'nyanja wa GFRP bar
Kuwonongeka kwa chloride kwa kulimbitsa chitsulo ndi chinthu chofunikira kwambiri chomwe chimakhudza kulimba kwa nyumba zomangira konkire zolimbikitsidwa m'mapulojekiti akunja. Kapangidwe ka girder-slab kamene kamagwiritsidwa ntchito kwambiri m'malo oimikapo sitima, chifukwa cha kulemera kwake komanso katundu waukulu womwe umanyamula, kamakumana ndi nthawi yopindika kwambiri komanso mphamvu zodula pakati pa girder yayitali komanso pa chithandizo, zomwe zimapangitsa kuti ming'alu ikule. Chifukwa cha momwe madzi a m'nyanja amachitira, mipiringidzo yomangira iyi imatha kuzizira pakapita nthawi yochepa kwambiri, zomwe zimapangitsa kuti mphamvu yonyamula katundu yonse ichepe, zomwe zimakhudza kugwiritsa ntchito bwino doko kapena ngozi zachitetezo.
Kugwiritsa ntchito: khoma la m'nyanja, kapangidwe ka nyumba ya m'mphepete mwa nyanja, dziwe la ulimi wa nsomba, thanthwe lopangira, kapangidwe ka madzi, doko loyandama
ndi zina zotero.
8. Ntchito zina zapadera za mipiringidzo ya GFRP
(1) Ntchito yapadera yotsutsana ndi kusokoneza kwa maginito
Zipangizo zoletsa kusokoneza ma radar m'malo mwa bwalo la ndege ndi asilikali, malo oyesera zida zankhondo, makoma a konkriti, zida za MRI, malo owonera zinthu m'mlengalenga, nyumba zolumikizirana ndi nyukiliya, nsanja zolamulira bwalo la ndege, ndi zina zotero, zingagwiritsidwe ntchito m'malo mwa zitsulo, zitsulo zamkuwa, ndi zina zotero. Zipangizo za GFRP ngati zinthu zolimbikitsira konkriti.
(2) Zolumikizira za Sandwich pakhoma
Khoma lotetezedwa ndi sandwich lomwe lapangidwa kale limapangidwa ndi ma panel awiri a konkriti ndi gawo loteteza pakati. Kapangidwe kake kamagwiritsa ntchito zolumikizira zatsopano za OP-SW300 glass fiber reinforced composite material (GFRP) kudzera mu bolodi loteteza kutentha kuti lilumikize ma panel awiri a konkriti pamodzi, zomwe zimapangitsa kuti khoma loteteza kutentha lichotse kwathunthu milatho yozizira pomanga. Chogulitsachi sichimangogwiritsa ntchito mphamvu ya LU-VE GFRP yosagwirizana ndi kutentha, komanso chimaperekanso mphamvu yonse ku mphamvu yophatikizana kwa khoma la sandwich.
