Ob leeg cementitious thiab epoxy grouts yog tsim los siv nyob rau hauv load, qhov twg ib tug muab tub lim yuav tsum tau ua raws li ib tug structurally suab khoom.
Sib tov los ntawm cov hmoov qhuav kom qhov sib xws, lawv tuaj yeem ua tau zoo heev los siv los ua cov khoom ntim tau, lossis tuaj yeem siv tau rau hauv daim ntawv ua kua ntau dua. Feem ntau cov grouts muaj cov khoom tsis-shrink uas txhais tau tias thaum lawv tawv, koj tshuav nrog lub hauv paus zoo kawg nkaus.
Ob hom muaj lawv qhov zoo - cia peb saib kom meej ntxiv ntawm qhov sib txawv ntawm cov cement raws li grouts thiab epoxy grouts.
Dab tsi yog cementitious grout?
Cementitious grout yog siv los tsim kom muaj qhov sib luag ntawm cov qauv hauv qab thiab cov hauv paus hauv paus. Nws enables txawm dispersal ntawm lub load rau hauv cov pob zeb uas twb muaj lawm. Piv txwv li, koj tuaj yeem txhim kho ib kem, ntxiv cov cementitious grout hauv qab rau cov thickness uas tau teev tseg, thiab koj kem thiab tag nrho cov load yuav hloov mus rau lub hauv paus pob zeb.
Cementitious grout yog tsim rau ntau yam ntawm cov txaj sib txawv thiab kho daim ntaub ntawv raws li hauv paus, bearing daim hlau thiab steel thav ntawv.
Dab tsi yog epoxy grout?
Zoo sib xws hauv kev ua haujlwm yog epoxy grout. Feem ntau siv rau hauv cov xwm txheej kub ntxhov, epoxy grout muaj kev loj hlob sai, txawm li cas los xij tsis haum rau kev siv raws li cov mercury nce. Yog tias siv rau hauv thaj chaw uas muaj qhov kub thiab txias, cov cementitious grout yuav yog qhov kev xaiv ntau dua.
Epoxy grouts kuj zoo li cov kua dej tsawg dua li cov cementitious grouts thiab qhov no tuaj yeem muaj qhov kev xaiv rau koj qhov project. Yog hais tias koj grouting nyob rau hauv cov khoom loj los yog baseplates nws yuav yooj yim dua los siv ib tug dawb ntws cementitious grout.
Epoxy grouts yog qhov zoo tshaj plaws rau cov cheeb tsam muaj zog siab, ua tiav lub zog thaum ntxov (los yog HES) thiab txhawb nqa cov khoom hnyav.
Grout xaiv rau nruj vs dynamic loading
Yog tias koj tab tom kho lub hauv paus ntawm cov khoom siv uas muaj ntau qhov chaw thau khoom, xws li tshuab nrog kev sib hloov lossis vibrating, epoxy grouts tuaj yeem ua tau ntev dua, muab qhov kev pabcuam siab tshaj plaws tsis siab dhau.
Tensile zogntawm grout yog ntsuas raws li Australian Standards. Yog tias koj qhov kev teeb tsa raug rau siab vibration lossis dynamic loading, koj yuav xav tau lub zog tensile ntau dua.
Cementitious grout kuj zoo tagnrho rau cov bolts, dowels, bearing pads, keyway pob qij txha thiab crane rails. Qhov no tsis yog-corrosive thiab non-metallic cement raws li cov khoom siv sai sai tsim muaj zog compressive sai.
Compressive zogyog muaj peev xwm tiv taus downward siab. Lub peev xwm ntawm cov grout kom ncav cuag qhov kawg compressive lub zog sai yog feem ntau tseem ceeb thaum cov cav tov yuav tsum tau muab tso rau hauv kev pab cuam ASAP.
Ua ntej koj xaiv ib tug grout
Txhawm rau txiav txim siab seb puas cementitious lossis epoxy yog hom zoo tshaj plaws ntawm grout siv rau koj qhov project, xav txog cov ntsiab lus hauv qab no:
Puas yuav xav tias lub grout yuav ua haujlwm ntawm qhov kub thiab txias? Qhov kev pabcuam siab tshaj plaws yog dab tsi?
Puas yog thaj chaw yuav raug grouted rau ntub thiab qhuav cycles thiab/los yog tshuaj lom neeg raug?
Cov packers thiab shims puas tuaj yeem muab tso tau yooj yim, zoo nyob rau hauv ciam teb ntawm thaj chaw grouting?
Puas yog cov cuab yeej tau txais kev txhawb nqa ruaj khov lossis nws puas yuav muaj zog? Yog tias nws txav, vibrates lossis tig, lub grout puas tsim ib daim ntawv cog lus txaus?
Puas muaj thaj chaw loj nyob rau hauv cov khoom ruaj khov los sau? Qhov no puas yuav yooj yim dua nrog cov dej ntws dawb es tsis yog tuab, ntim tau grout?
Puas yog cov teeb meem thermal expansion yog qhov tseem ceeb: koj cov khoom xaiv puas haum rau cov substrate uas twb muaj lawm?
Puas yog daim ntawv thov thickness pom zoo rau koj qhov project?
