Grouting Experiment Video (Tshuaj ntsuab)
Tom qab kev tsim kho cov khoom siv grouting tiav, lub sijhawm kho yuav tsum tau ua kom lub zog ntawm cov khoom siv grouting. Thaum kho thaum lub caij ntuj sov, nws tuaj yeem npog nrog cov hnab straw thiab kho nrog dej kom lub ntsej muag ntawm lub ntsej muag moist. Thaum lub caij ntuj no, curing, siab damping roj hmab bearings, thiab acceleration ntawm localization ntawm epoxy grout siv rau av qeeg-dawb redispersible roj hmab hmoov yuav ua txhaum qhov teeb meem uas txawv teb chaws lwm tus neeg tswj cov roj hmab hmoov ua lag luam nyob rau hauv kuv lub teb chaws. Thaum qhov kev tsim kho lub caij ntuj no tsis muaj qhov tshwj xeeb rau kev loj hlob ntawm lub zog, ib feem tom qab grouting yuav tsum tau them nrog zaj duab xis yas thiab npog nrog cov ntaub ntawv rwb thaiv tsev nyob rau lub sijhawm. Los ntawm cov kev taw qhia ntawm kev pom, mortar yuav tsum muaj peev xwm sib cog lus nrog ntau yam substrates thiab muaj tsawg shrinkage, siab compressive zog thiab zoo abrasion kuj. Lub hom phiaj tseem ceeb ntawm kev siv lub zog loj uas tsis yog shrinkage grouting thiab tom qab lub grouting pib, txoj hauj lwm siab grouting funnel yuav tsum tau siv thaum lub grouting nrug yog ≥.m, thiab cov grouting yog pib los ntawm qhov chaw los yog ib sab ntawm cov khoom. puag. Cov khoom siv grouting tuaj yeem tsis tsuas yog ua lub luag haujlwm ntawm cov kab noj hniav compaction, tab sis kuj muaj kev sib txuas zoo nrog cov pob zeb, uas tuaj yeem ua lub luag haujlwm ntawm kev kho cov pob qij txha thiab cov pob qij txha txias. .
