Thaum Pob Zeb Bolts Tsis Txaus: Lub Hwjchim ntawm Cable Anchors hauv Kev Pabcuam Sib Nrauj
Hauv kev mining hauv av thiab hnyav engineering, engineers feem ntau ntsib ib qho kev sib tw tseem ceeb: "Active Mining Zone" lossis cov pob zeb tawg yog tuab heev rau cov qauv 2.4-meter pob zeb bolts kom ncav cuag hauv av ruaj khov.
Qhov no yog qhov twgCable Anchors(tseem hu uaAnchor Cables) tuaj ua si. Raws li qhov siab -lub zog, hloov tau, thiab ntev - ntau yam kev daws teeb meem, cable anchors muab qhov sib sib zog nqus - zaum ruaj khov uas txheem bolting tshuab ua tsis tau.
Tsis zoo li cov hlau pob zeb bolts,Cable Anchorsyog tsim los ntawm siab- tensile steel strands (feem ntau yog 7-hlau los yog 19-xov hlau strands). Vim tias lawv hloov tau, lawv tuaj yeem tsim tau ntev ntev-feem ntau mus txog 6, 10, lossis txawm 20 meters-tso cia lawv thauj tog rau nkoj tob rau hauv cov pob zeb ruaj khov nyob deb ntawm lub ru tsev excavation.
2. Qhov tseem ceeb ntawm Cable Anchors
A. Extraordinary Tensile Strength
Cable anchors yog tsim los tiv thaiv cov khoom loj. Ib qho 17.8mm lossis 21.8mm siab -tensile cable thauj tog rau nkoj tuaj yeem muaj kev tawg ntau tshaj 300-600 kN, ntau dua li cov qauv rebar bolts feem ntau.
B. Kev yooj yim hauv qhov chaw txwv
Ib qho ntawm cov txiaj ntsig zoo tshaj plaws yog kev yoog raws. Hauv qhov qis- qhov siab qhov siab (piv txwv li, 3 meters siab), koj tsis tuaj yeem nruab ib lub 6-meter steel ntsia liaj qhov rooj. Txawm li cas los xij, 6-meterCable Anchortuaj yeem coiled thiab yooj yim ntxig rau hauv qhov borehole, ua kom muaj zog sib sib zog nqus tau nyob rau hauv qhov chaw nruj hauv av.
C. Ua Ntej Ua Ntej -Stressing Capability
Cable anchors feem ntau ntsia nrog tshwj xeebBarrel thiab Wedgeteeb. Qhov no tso cai rau lub cable ua "pre-stressed" siv hydraulic tensioner. Los ntawm kev siv thawj zaug load, lub cable nquag compresses lub pob zeb strata ua ke, tiv thaiv kev txav mus los ua ntej nws pib.
Mining engineers feem ntau hais txog cable anchors hauv cov xwm txheej hauv qab no:
Loj Span Intersections:Qhov twg lub ru tsev cheeb tsam yog dav dhau rau tus qauv bolting qauv tuav.
Fault Zones thiab Fractured Av:Qhov twg "xoo" txheej ntawm pob zeb yog tob tshaj qhov ntev ntawm tus qauv bolt.
Ntev -Lub Sij Hawm Infrastructure:Txoj kev thauj khoom loj lossis kev cob qhia hauv av uas xav tau lub neej ua haujlwm 20+ xyoo.
Secondary Support:Raws li kev ntsuas kev nyab xeeb ntxiv tau teeb tsa tom qab thawj lub bolting los ua haujlwm lig -theem kev ntxhov siab redistribution.
4. Cov Cheebtsam tseem ceeb ntawm Kev Pabcuam Cable
Txhawm rau kom muaj kev nyab xeeb siab tshaj plaws, lub thauj tog rau nkoj cable yuav tsum tau kho raws li qhov ua tiav. Ntawm Zhongfu Mining, peb muab tag nrho cov siab - zoo sib dhos:
Steel Strand: Siab-tensile, qis-so steel strand.
Barrel thiab Wedge: Lub precision -engineered gripping mechanism uas tswj qhov nro.
Cable Phaj: Heavy- cov phaj ua haujlwm tsim los tiv taus siab ua ntej- kev nyuaj siab loads.
Grouting Khoom: Cov kev daws teeb meem tshwj xeeb los xyuas kom meej tias tag nrho qhov ntev ntawm cov kab txuas txuas nrog lub pob zeb.
FAQ
Q: Cov qauv thoob ntiaj teb dab tsi ua koj tus kheej -drilling bolts ua raws li?
A: Peb lub tshuab SDA (xws li R- xov thiab T- xov) yog tsim los ntawm nruj raws li ISO 10208 thiab ASTM cov qauv. Peb siv siab - lub zog seamless steel tubing kom ntseeg tau tias muaj zog tensile zoo dua thiab muaj zog txaus rau kev thov cov mining thiab tunneling tej yaam num.
Q: Vim li cas SDA bolts ua haujlwm zoo dua li cov pob zeb pob zeb hauv av tawg?
A: Cov bolts ib txwm xav tau ua ntej -drilled qhov uas feem ntau tawg hauv av xoob. Lub SDA system sib txuas cov drilling, grouting, thiab anchoring rau hauv ib qho kev ua haujlwm. Qhov no tshem tawm qhov xav tau ntawm cov kav dej thiab tiv thaiv lub qhov borehole, txuag txog li 50% ntawm lub sijhawm installation.
Q: Koj cov txiv ntseej kheej kheej ua li cas tuav cov pob zeb tsis sib xws?
A: Peb precision-engineered spherical txiv ntseej (dome ceev), thaum ua ke nrog domed daim hlau, tso cai rau 7 mus rau 10 degrees ntawm angular them. Qhov no ua kom ntseeg tau tias lub ntsia liaj qhov rooj tswj xyuas qhov ruaj ntseg, qhov chaw thau khoom faib tawm txawm tias lub ntsej muag lub ntsej muag tsis sib xws lossis tsis sib xws.
Thaum lub pob zeb bolts yog "khob cij thiab butter" ntawm kev txhawb nqa hauv av,Cable Anchorsyog txoj cai pov hwm qhov kawg rau siab - kev pheej hmoo thiab siab - thaj chaw muaj kev ntxhov siab. Kev nkag siab thaum twg thiab yuav ua li cas los siv qhov sib sib zog nqus cable yog qhov tseem ceeb rau kev tiv thaiv lub ru tsev loj thiab ua kom qhov project ntev.
Nrhiav rau siab - muaj peev xwm txhawb kev daws teeb meem?
Zhongfu Mining muaj siab - tensileCable Anchors, Barrel thiab Wedge sets, thiab customizedAnchor phajkom haum rau koj qhov xav tau tshaj plaws hauv qhov sib sib zog nqus- cov haujlwm tsuas.
