Chidule cha Ntchito
Jazan Economic City ili pamtunda wa 725km kumwera kwa Jeddah City ndi 80km kuchokera ku Jazan City. Jazan New Economic City ndi likulu la mafakitale ndi zamalonda lomwe lili ndi doko lotanganidwa, koma derali limakonda kusefukira chifukwa cha mvula yamphamvu komanso kusayenda bwino kwa madzi. Njira yotulutsira madzi osefukira ya 21.3km itenga gawo lofunikira poteteza zida zamatawuni komanso chitetezo cha anthu.
The Jazan spillway panopa ndi ntchito yaikulu kwambiri padziko lonse lapansi yomwe ikugwiritsidwa ntchitoMtengo wa GFRP monga kulimbikitsa konkire. Makasitomala a polojekitiyi ndi Saudi Aramco Company ndi Dubai Pultron Company.
Katundu wa FRP Materials
Fiberglassndi azinthu zophatikiza , nthawi zambiri amapangidwa ndi vinyl resin ndi galasi fiber. Kugwiritsiridwa ntchito kwa bar code PRV monga konkire yolimbikitsidwa kwakhala kutchuka m'zaka zaposachedwa, monga omanga adzidalira kwambiri zipangizo ndi kupita patsogolo kwa njira zopangira, komanso mpikisano wowonjezereka wakhala wopikisana kwambiri poyerekeza ndi rebar yachikhalidwe pamtengo. Kuphatikiza pa kukana dzimbiri, ndodo za FRP zimakhala ndi mphamvu zenizeni zenizeni, kusalowerera ndale kwamagetsi komanso kutopa kwambiri. Kuphatikiza apo, kulemera kwa bar yopepuka kumachepetsanso ndalama zotumizira ndi kukhazikitsa. Ngakhale kukula kwamafuta ndi kuuma kwapakati pakati pa FRP rebar ndi konkire ndizabwino, zotanuka modulus, kumeta ubweya ndi kupsinjika kwapang'onopang'ono ndizochepa. Othandizira atatu apadziko lonse lapansi a FRP ndodo adalemekezedwa chifukwa chaukadaulo wawo wapamwamba kwambiri, luso lawo laukadaulo komanso malo omwe ali. Kuteteza chilengedwe kumatanthauza kuti anthu amateteza mwanzeru zinthu zachilengedwe, kugwiritsa ntchito bwino zinthu zachilengedwe, komanso kupewa kuipitsa ndi kuwononga chilengedwe. Malo oipitsidwa ndi owonongeka ayenera kuthetsedwa mokwanira kuti apange malo abwino ku moyo wa munthu ndi ntchito. Kusefukira kwa Jazan kunali kosinthira kwakukulu pamakampani opanga zomangamanga, chifukwa inali imodzi mwama projekiti akuluakulu padziko lonse lapansi omwe amagwiritsa ntchito.Chithunzi cha FRPngati konkriti.
Al Yamama, kampani yomwe imamanga njanjiyi, idathira konkire yopitilira 1,500 masikweya mita patsiku pakumanga, ndikupangitsa kuti ikhale imodzi mwantchito zomanga ngalande zothamanga kwambiri zomwe zidachitikapo mu ufumuwo. Opitilira masikweya mita 11 miliyoni a FRP rebar adaperekedwa panthawi yonseyi, pomwe pafupifupi 82 peresenti anali ndodo zowongoka ndipo 18 peresenti anali ma calipers.
Kuyankha Zosintha Zamapangidwe a Njira Zowongolera Chigumula
Pulojekiti ya kukula uku imasintha nthawi ndi nthawi. Kusiyanasiyana kwa mapangidwe ndi kuchuluka kumafuna kuchulukitsidwa kwa magawo opanga kuti akwaniritse masiku obweretsa. Kuti izi zitheke, ndi ukatswiri ndi chithandizo cha gulu la uinjiniya ndi ochita nawo kafukufuku, makina owonjezera ogaya okha ndi chitoliro chatsopano cha bender adayikidwa. Kutumizidwa kwachangu kwa zidazo kunakulitsa zotulukapo ndipo kunakumana mosavuta ndi nthawi yomanga. maziko. Vuto lina ndi mawonekedwe a dambo. Kapangidwe kameneka kanafuna kuti pakhale mgwirizano wokulirapo mu slab iliyonse, kotero kunali koyenera kupereka tendon yosinthika yomwe imatha kusinthasintha kumbuyo. Nthawi zonse, izi sizikanatheka, koma pambuyo poyesa gawo la uinjiniya ndi akatswiri a pultrusion, kupindika kovutirako kumeneku kunamalizidwa ndipo kukonzekera kwa FRP rebar kunamalizidwa ndikuperekedwa ku polojekitiyi pa nthawi yake.
Zotsatira Zabwino Zogwiritsa Ntchito FRP Rebar
Zopanda dzimbiri komanso kukana kwambiri kwamankhwala - Chifukwa cha kugwiritsa ntchito ma polima a fiberglass ochita bwino kwambiri, kulimba kwake kwapadera kumatsimikizira zaka 100 za moyo popanda kukonzanso. Jishan Spillway idzateteza okhalamo ndi mzinda ku zowonongeka zomwe zimachitika chifukwa cha kusefukira kwa madzi. Pazaka zitatu zapitazi za polojekitiyi, aramco ndi kontrakitala adagwira ntchito limodzi kuti aphunzire zabwino ndi zoyipa zogwiritsa ntchito rebar ya GFRP m'malo mwa rebar yokhala ndi epoxy. Kwa 100ft x 100ft slab konkire yokhala ndi yankho la 0,2m GFRP, kugwiritsa ntchito mipiringidzo yachikhalidwe kumachepetsa mtengo wandalama ndi 10%, mtengo wa konkriti wokhazikika ndi 11%, mtengo wachitsulo womanga ndi 42%, mtengo wa cranes ndi 100% ndi 67% % ya ndalama zogwirira ntchito. Ndalama zonse zomwe zasungidwa mwachindunji pulogalamu yowonjezera ya PRGF inali 21%. Zosungazo zimakhala zokulirapo pamene kuwunika kwa moyo wanthawi zonse kumaganiziridwa. Pazinthu zina zazikulu zofanana, kulimbikitsa FRP kungathenso kuchepetsa mtengo kwambiri.
Izi ndizochitika zenizeni. Monga msika wotsogola ku China, GRECHO imapereka zida zapamwamba za fiberglass, kuphatikiza FRP rebar ndi zinthu zina za FRP, zopangira malonda, mafakitale, ndi nyumba. GRECHO ikhoza kukupezerani FRP yapamwamba komanso yotsika mtengo pophatikiza zinthu zapakhomo. GRECHO ikugwirizananso ndi zimphona zapamwamba za fiberglass padziko lonse lapansi.
