Tswj cov khoom siv raw khoom

1.1 Tib batch ntawm raw khoom yuav tsum tau siv kom deb li deb tau nyob rau hauv tib lub project. Xaiv tib lub hauv paus chiv keeb, tib hom, tib xim ntawm cov cement, xuab zeb, gravel thiab admixtures thiab lwm yam ntaub ntawv raw, raw cov ntaub ntawv huv si thiab tsis muaj impurities, tuaj yeem ua tau zoo kom tsis txhob pom cov xim pob zeb tsis zoo ib yam lossis qhov chaw vim qhov raw cov ntaub ntawv tsis yog ib yam nkaus.
1.2 Txhim kho qhov kev tshuaj xyuas ntawm qhov chaw ntawm cov cement
(1) Kev tshuaj ntsuam xyuas: Tshawb xyuas lub Hoobkas tsim nyog daim ntawv pov thawj ntawm txhua batch ntawm cement nkag mus rau hauv qhov chaw, thiab xa cov qauv mus rau lub chaw kuaj xyuas los txiav txim siab nws lub zog, pib thiab qhov kawg ntawm lub sijhawm, kev ruaj ntseg thiab lwm yam ntsuas. Tsuas yog txhua qhov tsim nyog cement tuaj yeem siv tau.
(2) Kev kuaj xyuas kev cia khoom. Xyuas kom cov cement khaws cia rau hauv qhov chaw qhuav, zoo-ventilated, weatherproof, thiab noo-pov thawj qhov chaw. Hauv pem teb yuav tsum tau pav nrog cov neeg pw tsaug zog, tsawg kawg 30cm saum av. Cov cement yuav tsum tau siv sai li sai tau tom qab nkag mus rau hauv qhov chaw. Kev saib xyuas tshwj xeeb yuav tsum tau them nyiaj rau kev tiv thaiv cov dej ntws ntawm cov dej tsis tu ncua lossis nag-soaked cement rau hauv qhov chaw tsim kho. Cov cement no yuav tsis tsuas yog cuam tshuam rau lub zog ntawm cov pob zeb, tab sis kuj ua rau cov pob zeb ua pob zeb muaj qhov tsaus ntuj, cuam tshuam rau qhov pom ntawm pob zeb zoo.
1.3 Ntxiv dag zog rau qhov chaw soj ntsuam ntawm cov xuab zeb thiab pob zeb cov ntaub ntawv
(1) Kev tshuaj ntsuam xyuas: kuaj txhua lub sijhawm, tshuaj ntsuam, cov ntsiab lus impurity, crushing tus nqi thiab lwm yam khoom ntawm cov xuab zeb thiab pob zeb hauv cov xuab zeb. Tswj cov gradation ntawm cov xuab zeb thiab pob zeb. Kev xaiv cov xuab zeb yuav tsum yog cov xuab zeb nruab nrab thiab sib npaug sib npaug, tsis yog qhov siab tshaj qhov feem pua ​​​​ntawm cov txheej txheem gradation, uas yog qhov tsim nyog rau lub compactness ntawm pob zeb.
