Tswj Deforming Av: Vim Li Cas Kev Sib Nqus Stabilizers Outperform hauv Squeezing Pob Zeb
Txhua tus engineer underground nws thiaj li khiav mus rau hauv av uas tsis kam nyob twj ywm. Txawm hais tias koj hu nws "sab hauv av," "sov av nplaum," lossis tsuas yog lub ru tsev hnyav, cuam tshuam nrog lub qhov av uas xav kaw rau hauv koj yog mob taub hau loj.
Yog tias koj sim tawm tsam cov pob zeb zoo li no nrog kev txhawb nqa nruj heev- zoo li qhov tawv tawv, tag nrho -grouted rebar bolt- feem ntau koj yuav xaus nrog snapped steel thiab txoj kev ua tsis tiav. Lub pob zeb muaj ntau dhau lawm; nws yuav rhuav txhua yam uas tsis kam txav nrog nws.
Qhov ntawd yog qhov Friction Stabilizers, universally hu ua Split Sets, ua pov thawj lawv tsim nyog. Lawv tsis tawm tsam lub pob zeb txav; lawv tswj nws. Cia peb saib cov geometry thiab physics ntawm vim li cas lawv ua haujlwm zoo hauv av deforming.
Thaum xub thawj siab ib muag, ib qho kev sib cais zoo li yooj yim: C- zoo li tus steel raj nrog ib tug tapered kawg thiab ib tug welded- ntawm lub nplhaib rau lub thauj tog rau nkoj phaj. Tab sis engineering yog tag nrho hauv lej ntawm tus ntoo khaub lig-section.
Sab nraud txoj kab uas hla ntawm lub raj yog txhob txwm tsim kom muaj me ntsis loj dua lub laum qhov. Thaum koj tsav nws mus rau hauv lub qhov (siv pneumatic rauj lossis jumbo rig), C-puab raug yuam kom compress me ntsis.
Qhov no tsim loj, nruam radial kev sib txhuam raws tag nrho ntev ntawm phab ntsa borehole.
Tsis zoo li lub ntsiab lus -anchored mechanical bolt, kev sib txhuam stabilizer tuav lub pob zeb los ntawm sab saum toj mus rau hauv qab, faib cov khoom sib npaug.
2. Lub Hwj Chim ntawm "Yielding" (Ua Haujlwm Nrog Pob Zeb)
Ntawm no yog lub ntsiab yog vim li cas kev sib txhuam stabilizers zoo nyob rau hauv squeezing av: lawv muaj peev xwm yield.
Thaum lub strata nyob ib puag ncig pib converge, ib lub pob txha pob txha muaj kev nyuaj siab heev kom txog thaum nws snaps. Ib qho kev sib cais, txawm li cas los xij, muaj ib qho ua tau - nyob rau hauv tso tawm valve. Yog hais tias qhov kev txav hauv av tshaj qhov kev sib txhuam, cov raj sab hauv tuaj yeem plam me ntsis hauv qhov borehole yam tsis poob nws lub peev xwm tuav.
Nws absorbs lub zog kinetic ntawm lub pob zeb txav.
Nws deforms gracefully thaum tuav lub zog clamping siab ntawm lub phaj nto thiab lub ntsej muag pob zeb.
Nws yog qhov tseem ceeb ntawm kev poob siab absorber rau koj lub qhov.
Ib cag ntawm geomechanics, tus thawj tswj hwm qhov chaw nyiam sib faib cov txheej txheem rau ib qho laj thawj yooj yim:ceev.
Hauv kev nrawm nrawm -paced txoj kev loj hlob, txhua feeb suav. Resin bolts yuav tsum tau drilling, qhov ntxuav, capsule insertion, spinning, thiab tos lub sij hawm kho. Muab faib? Koj laum lub qhov, tsav lub ntsia liaj qhov rooj hauv tsev, thiab koj ua tiav. Tsis muaj tshuaj lom neeg tos lub sijhawm. Rau kev txhawb nqa ib ntus lossis tam sim lub ntsej muag stabilization tam sim ntawd tom qab tawg, tsis muaj dab tsi ntaus qhov nrawm ntawm kev sib txhuam stabilizer.
4. Qhov Kev Muaj Peev Xwm Muaj Peev Xwm: Qhov Chaw Tsis Siv Lawv
Ua ncaj ncees txog cov khoom txwv yog qhov zoo engineering yog txhua yam hais txog. Split sets muaj nyias phab ntsa steel piv rau hnyav -cov haujlwm rebar bolts.
Yog tias koj tab tom cuam tshuam nrog cov dej hauv av acidic los yog ntub dej, tsis kho cov hlau sib cais yuav corrode sai. Yog li ntawd, nyob rau hauv corrosive ib puag ncig, koj yuav tsum sivKub-Dip Galvanized (HDG) cais pawg.
Lawv kuj yuav tsum tsis txhob yog koj thawj qhov kev xaiv rau loj, tuag- hnyav li qub loads nyob rau hauv nyuaj, blocky pob zeb qhov twg ib tug tawv resin daim ntawv cog lus yuav tsum nruj me ntsis. Sib piv cov cuab yeej rau geology.
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 tsoo 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 casing thiab tiv thaiv borehole vau, 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.
Kev cuam tshuam nrog deforming hauv av yog kev ua si ntawm physics, tsis yog brute quab yuam. Los ntawm kev tso cai hlais thaum tswj kev sib txhuam radial tsis tu ncua, kev sib cais ua rau koj hloov tau yooj yim, txhim khu kev qha kab ntawm kev tiv thaiv tawm tsam converging strata.
NtawmZhongfu Mining, peb dov peb cov kev sib txhuam stabilizers los ntawm qib siab - qib steel nrog nruj tswj qhov qhov kam rau ua. Qhov ntawd txhais tau hais tias lub zog sib xyaw ua ke thiab txhim khu kev qha rub - tawm kev sib txhuam txhua zaus koj tsav ib qho rau hauv lub ru tsev.
