Ob chav txheej iav yog quilt rau haus dej thiab tshuaj yej.Vim nws yog ob-txheej, nws muaj kev txuag hluav taws xob zoo heev thiab zoo nkauj tsos.Cov hauv qab no yog cov kev paub txog kev kub siab grouting.
Cov kev lig kev cai ntawm grouting yog txhaj cov slurry rau hauv cov qauv gypsum, thiab cov slurry pwm absorbs dej ntawm slurry los tsim ib tug embryo nrog ib tug tej thickness.Txawm li cas los xij, nyob rau hauv lub xeev ntuj no, cov txheej txheem filtration grouting yog qeeb, qhov kev ua tau zoo yog tsawg, thiab cov qauv ntawm lub embryo ntawm lub khob iav ob txheej yog inconsistent, cov ntsiab lus dej yog siab, thiab nws tsis yooj yim rau demould, uas ua rau kom qhuav shrinkage thiab firing shrinkage ntawm ob-txheej iav khob loj, uas yog ib qho yooj yim ua rau deformation tsis xws luag.
Txhawm rau kom nqus tau sai sai hauv cov dej hauv slurry, xyuas kom meej qhov compactness ntawm lub embryo thiab tiv thaiv qhov tshwm sim ntawm cov teeb meem xws li embryo cracking thiab delamination, high-pressure grouting yog siv nyob rau hauv zus tau tej cov iav ob txheej.
Kev kub siab grouting yog cov txheej txheem siab heev los ua ob txheej iav khob.Lub khob tsim los ntawm cov txheej txheem no muaj qhov zoo heev thiab tuaj yeem txo tus nqi.
