Resin vs. Cement Grouting: Qhov twg yog qhov tiag "Gold Standard" rau kev txhawb nqa mus tas li?
Hauv kev tsim cov kev tsim kho hauv av mus tas li, ob peb qhov kev sib cav tsis tu ncua ntawm cov mining thiab civil engineers raws li kev xaiv ntawmResin AnchoringthiabCement Grouting.
Ob txoj kev thov kom muab "tus qauv kub" rau kev ruaj ntseg. Txawm li cas los xij, txhua tus neeg uas tau ua haujlwm ntev ntev - txoj kev txoj kev lossis txoj haujlwm tunnel paub tias qhov kev xaiv "txoj cai" tsis yog hais txog kev nyiam- nws yog hais txog kev sib piv cov khoom mus rau qhov tseeb ntawm geological.
Resin capsules tau revolutionized mining los ntawm kev ua kom "point-rau- thauj tog rau nkoj" ceev.
Tus Pro:Lub ntsiab kom zoo dua yog lub sijhawm. Resin anchors ncav cuag lawv lub peev xwm thauj khoom hauv feeb, tsis yog hnub. Hauv siab - cov mines ntau lawm, qhov twg txhua qhov thib ob suav, resin tso cai rau kev nce qib mus tas li yam tsis tau tos rau lub sijhawm tshuaj lom neeg los rub rau.
Kev txwv:Resin yog "muaj" tov. Nws ua haujlwm zoo kawg nkaus hauv cov pob zeb ruaj khov lossis me me pob zeb tawg. Txawm li cas los xij, nyob rau thaj tsam hnyav lossis tob, siab - qhov chaw muaj kev ntxhov siab, cov resin tuaj yeem ua nkig. Nws tsis sau cov voids loj lossis ntxiv dag zog rau pob zeb loj nws tus kheej; nws tsuas yog glues lub bolt rau lub qhov.
2. Cement Grouting: Qhov tob-Rock Stabilizer
Cement grouting (siv hollow grouting bolts) yog ib txwm hnyav hnyav ntawm kev txhawb nqa hauv av.
Tus Pro: Nws ua ntau tshaj li tsuas yog thauj tog rau nkoj ib lub bolt- nws sib sau ua ke hauv av. Nyob rau hauv lub siab, grout penetrates fissures, tawg, thiab voids, zoo tig ib tug loj ntawm xoob, tawg pob zeb mus rau hauv ib tug khoom, ntxiv dag zog "beam." Qhov no yog vim li cas nws yog qhov mus - mus rau qhov mus tas li thiab txoj kab nqes stabilization.
Qhov Kev Txwv: Nws yog kev ua haujlwm - hnyav thiab qeeb. Lub sijhawm kho rau cov cement tuaj yeem nyob ntawm 24 teev mus rau ob peb hnub, uas feem ntau tsis tuaj yeem lees txais sai sai - txav mus rau kev txhim kho mining ntsej muag.
Yog li, qhov twg yog tus qauv kub? Yog tias koj txhais tus qauv los ntawm kev tsim khoom, resin yog tus yeej. Yog tias koj txhais nws los ntawm geological kev txhawb zog thiab kev ua neej ntev, cement yog huab tais.
Txawm li cas los xij, niaj hnub kev tswj hwm hauv av tau nce siab siv txoj hauv kev hybrid:
Kev Pabcuam Tseem Ceeb: Siv Resin-Anchored Thread Bolts rau tam sim, nrawm-paced kev txhawb nqa thaum lub sijhawm nce ntawm qhov.
Kev them nyiaj yug Thib Ob: Txhim kho Hollow Grouting Bolts tom qab hauv qhov project lub neej voj voog los txhawb cov strata nyob ib puag ncig yog tias av siab nce lossis yog tias ntev - kev saib xyuas lub sij hawm qhia tau hais tias muaj zog ntau dhau.
4. Kev txiav txim siab: Daim ntawv teev npe ceev
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: Qhov tseeb -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: Dab tsi thoob ntiaj teb cov qauv ua koj tus kheej -drilling thauj tog rau nkoj 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 muaj txiaj ntsig 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.
