Fiberglass Rock Bolt
Sharaxaada Alaabta
Barroosinka Fiberglass waa shay dhisme ah oo sida caadiga ah ka samaysan xidhmooyin fiberglass ah oo xoog badan oo lagu duuduubay resin ama matrix sibidhka. Waxay muuqaal ahaan la mid tahay rebar birta, laakiin waxay bixisaa miisaan ka fudud iyo iska caabin daxalka weyn. Barroosinnada fiberglassku caadi ahaan waa wareegsan yihiin ama qaab ahaan waa dun, waxaana lagu habeyn karaa dhererka iyo dhexroorka codsiyada gaarka ah.
Tilmaamaha Alaabta
1) Xoog Sare: Barroosinnada fiberglass-ku waxay leeyihiin awood cufan oo aad u fiican waxayna u adkeysan karaan culeysyada xajinta.
2) Fudud: Barroosinnada fiberglassku way ka fudud yihiin birta dhaqameed, taas oo sahlaysa in la raro lana rakibo.
3) Iska caabinta daxalka: Fiberglass ma daxaloobayo mana daxaloobayo, sidaa awgeed waxay ku habboon tahay deegaanka qoyan ama daxalka leh.
4) Insulation: Dabeecadda aan biraha ahayn awgeed, barroosinnada fiberglass-ku waxay leeyihiin sifooyin dahaadh ah waxaana loo isticmaali karaa codsiyada u baahan dahaarka korantada.
5) Habaynta: Dhexroorka iyo dhererka kala duwan ayaa la cayimi karaa si loo buuxiyo shuruudaha mashruuc gaar ah.

Faa'iidooyinka alaabta
1) Kor u qaadida xasiloonida ciidda iyo dhagaxa: Barroosinnada fiberglass-ka ah waxa loo isticmaali karaa in kor loogu qaado xasilloonida ciidda ama dhagaxa, taas oo yaraynaysa khatarta dhul go’a iyo burburka.
2) Qaab-dhismeedka Taageerada: Waxaa caadi ahaan loo isticmaalaa in lagu taageero qaab-dhismeedka injineernimada sida tunnelyada, qodista qodista, jeexyada iyo tunnelyada, bixinta xoog iyo taageero dheeraad ah.
3) Dhismaha dhulka hoostiisa: Barroosinnada fiberglass-ka ah waxaa loo isticmaali karaa mashaariicda dhismaha dhulka hoostiisa, sida tunnel-yada dhulka hoostiisa mara iyo meelaha baabuurta la dhigto ee dhulka hoostiisa ah, si loo xaqiijiyo badbaadada iyo xasilloonida mashruuca.
4) Horumarinta Ciidda: Waxa kale oo loo isticmaali karaa mashaariicda horumarinta ciidda si kor loogu qaado awoodda carrada.
5) Kharashka kaydinta: Waxay dhimi kartaa gaadiidka iyo kharashka shaqada sababtoo ah miisaankeeda fudud iyo rakibidda fudud.
Codsiga Alaabta
Barroosinka Fiberglass waa qalab injineernimo madaniga ah oo badan oo loogu talagalay codsiyo kala duwan, oo bixiya xoog iyo xasillooni la isku halayn karo iyadoo la dhimayo kharashyada mashruuca. Xooggeeda sare, caabbinta daxalka iyo habaynta ayaa ka dhigaysa mid caan ku ah mashaariic kala duwan.
