Yuav ua li cas yuav thiab siv cov pob zeb sib xyaw kom raug?

Kev yuav khoom kom raug thiab siv cov khoom sib xyaw ua ke tuaj yeem tsim kev lag luam thiab kev muaj txiaj ntsig zoo. Nws tsis tsuas yog txhim kho pob zeb ua kom muaj zog tab sis kuj txo cov nqi ntawm cov pob zeb sib xyaw tsim. Cov txheej txheem tshwj xeeb yog raws li hauv qab no:

01. Kev Xeem Phaj

Kev ntsuam xyuas cov ntsuas kev ntsuas ntawm cov khoom sib xyaw yog ib kauj ruam tseem ceeb ua ntej kev sib tham txog kev yuav khoom. Los ntawm kev sim, cov qauv tsim nyog rau ntau yam kev ntsuas ntawm cov khoom sib xyaw yuav tsum raug tsim.
Cov ntsuas no suav nrog cov ntsiab lus ntawm cov khoom, cov dej txo qis, qhov ntom ntom, muab tshuaj txhuam dej, thiab cov dej ua kom txo qis. Nws raug nquahu kom siv cov pob zeb ua kom txo qis tus nqi raws li qhov taw qhia tseem ceeb los ntsuas qhov zoo ntawm cov khoom sib xyaw.

02. Theem kev yuav khoom

Thaum cov qauv tsim nyog rau cov khoom sib xyaw tau raug txiav txim siab, kev sib tham txog kev yuav khoom tuaj yeem pib. Nws raug nquahu kom ua kev sib tw ntawm cov neeg tsim khoom sib xyaw ua ke raws li cov qauv tsim nyog tau tsim los ntawm kev sim. Raws li qhov kev pom zoo tias cov khoom siv sib xyaw ua tau raws li qhov xav tau ntawm kev sib tw, tus neeg muag khoom yuav tsum raug xaiv raws li lub hauv paus ntsiab lus ntawm tus nqi qis tshaj.
Nyob rau tib lub sijhawm, tus nqi yuav tsum tsis yog tib qho kev ntsuas rau kev xaiv cov tuam ntxhab. Tej yam xws li kev tsim muaj peev xwm, kev thauj mus los, thiab kev muaj peev xwm xa khoom yuav tsum raug txiav txim siab. Ntawm cov npe tseem ceeb hauv kev ua lag luam, "Jiye Changqing" pob zeb superplasticizer tau txais kev ntseeg siab ntawm ntau cov nroj tsuag batching nrog nws cov khoom siv dav dav rau cov nroj tsuag loj loj lossis cov haujlwm loj engineering, nrog rau nws cov khoom zoo heev thiab kev pab cuam tom qab muag. peev xwm.

03. Theem Txais

Batching nroj tsuag yuav tsum tau kuaj cov khoom sib xyaw ua ntej lawv muab tso rau hauv warehouses. Tsuas yog cov khoom sib xyaw ua tau raws li cov qauv pom zoo hauv daim ntawv cog lus tuaj yeem lees txais. Nws raug nquahu kom sib txawv ntawm cov ntsuas tseem ceeb thiab cov cim qhia siv.
Los ntawm kev xyaum mus sij hawm ntev, nws tau pom tias qhov ntsuas tseem ceeb rau cov khoom sib xyaw yog cov dej txo qis (paste-sand) thiab cov dej ua kom txo qis, thaum cov ntsuas ntsuas suav nrog qhov ntom ntom (qhov tshwj xeeb lub ntiajteb txawj nqus), cov ntsiab lus ruaj khov, thiab cement paste fluidity.
Vim muaj kev txwv lub sij hawm, cov ntsuas feem ntau raug sim thaum lub sij hawm lees txais suav nrog qhov ntom ntom, cement paste fluidity, thiab dej txo tus nqi (paste-sand).
Yog tias qhov kev lees paub lees paub pom tias cov khoom sib xyaw tsis ua raws li cov qauv, cov lus pom zoo yog raws li hauv qab no:

Rov qab los:Yog tias cov dej txo qis qis dua qhov qis dua ntawm cov qauv tsim nyog, cov khoom siv yuav tsum tau rov qab.

Kev siv downgraded:Hauv cov xwm txheej ceev uas tam sim no cov khoom lag luam ntawm cov khoom siv tsis tuaj yeem ua tau raws li qhov xav tau, kev siv qis qis tuaj yeem sib tham. Qhov no feem ntau suav nrog nce qhov ntau npaum li cas los them rau qhov txo qis dej, nrog tus nqi them los ntawm tus neeg muag khoom.

Nws raug nquahu kom qhia txog kev tuav ntawm kev tsis ua raws li kev cog lus ntawm kev yuav khoom kom tsis txhob muaj kev tsis sib haum xeeb thaum muab cov khoom sib xyaw ua ke tsis haum.

04. Phaj siv

Feem ntau, cov neeg soj ntsuam zoo yuav tsum nruj me ntsis ua raws li kev tsim cov pob zeb sib xyaw, suav nrog cov tshuaj sib xyaw.

Ua ntej thiab thaum lub sij hawm tsim khoom txhua hnub, cov neeg soj ntsuam zoo yuav tsum kuaj cov dej noo ntawm cov xuab zeb thiab gravel aggregates los coj kev tsim khoom.

Thaum cov khoom siv raw khoom hloov pauv, kev hloov kho rau kev sib xyaw ua ke yuav tsum tau ua kom sai. Kev xav tau dej ntau ntxiv ntawm cov ntaub ntawv cementitious thiab aggregates, nrog rau kev txo cov dej txo qis ntawm cov khoom sib xyaw, tuaj yeem ua rau cov dej tsis txaus. Txoj hauv kev kom raug yog txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhav

05. Kev soj ntsuam tas li

Admixtures uas ua tau raws li cov qauv kev cog lus thaum lub sij hawm kuaj ua ntej cia tuaj yeem khaws cia. Txawm li cas los xij, vim tias tej zaum yuav muaj qhov tsis sib xws ntawm tus nqi txo cov dej thiab cov txiaj ntsig los ntawm kev sim sib xyaw, kev sim niaj hnub ntawm cov khoom sib xyaw yog pom zoo tom qab cia.
Kev ntsuam xyuas yuav tsum suav nrog cov ntsuas xws li cov dej ua kom txo qis thiab cov ntsiab lus ruaj khov, nrog rau cov dej ua kom txo qis yog qhov ntsuas tseem ceeb uas yuav tsum tau ua raws li qhov yuav tsum tau ua.
Yog tias qhov kev hloov pauv tseem ceeb hauv qhov kev txo qis ntawm cov dej hauv cov pob zeb tau pom, cov qauv yav dhau los ntawm cov khoom siv tsim nyog yuav tsum tau muab piv rau kev txheeb xyuas seb qhov kev hloov pauv yog vim li cas cov khoom siv los yog lwm yam khoom siv raw. Raws li kev soj ntsuam, cov neeg soj ntsuam zoo yuav tsum tau kho cov tshuaj sib xyaw kom sai kom ntseeg tau tias qhov sib piv ntawm cov dej-cement tseem nyob hauv cov qauv tsim, tswj kev ua vaj tse. Nyob rau tib lub sijhawm, cov neeg muag khoom ntawm cov khoom siv raw cov lus nug yuav tsum tau ceeb toom tam sim rau kev txhim kho kom zoo.

06. Kev Sib Tw Sib Tw

Txhawm rau kom ntseeg tau tias qhov tsim nyog ntawm kev tsim khoom sib xyaw tsim, nws raug nquahu kom ua qhov kev sim sib xyaw ua pov thawj rau feem ntau siv pob zeb sib xyaw tsim yam tsawg kawg ob zaug hauv ib hlis.
Nws tau raug pom tias feem ntau cov nroj tsuag batching uas muaj teeb meem nrog cov pob zeb muaj zog lossis cov nqi siab tsis muaj kev sim sib xyaw ua pov thawj rau lawv cov qauv sib xyaw ua ke. Kev ntsuam xyuas kev sib xyaw ua ke ntawm kev sib xyaw ua ke yog kev ntsuam xyuas zoo ntawm cov khoom siv pob zeb uas twb muaj lawm, kev ua haujlwm tau zoo, thiab lub zog.

Xaus

1. Kev nkag siab yuam kev ntawm kev siv cov khoom sib xyaw hauv cov nroj tsuag batching tshwm sim los ntawm qhov tsis muaj kev nkag siab ntawm cov txheej txheem thiab cov haujlwm tseem ceeb ntawm cov khoom sib xyaw, nrog rau kev paub tsis txaus ntawm qhov cuam tshuam ntawm cov dej-cement piv rau kev ua vaj tse.
2. Kev kho cov kev xav tsis zoo no yuav tsum muaj kev tswj hwm thoob plaws txhua theem, suav nrog kev sim, kev yuav khoom, kev lees paub, kev siv, kev sim niaj hnub, thiab kev sim sib xyaw ua pov thawj. Kev ua kom muaj zog ntawm cov pob zeb yog nyob rau hauv kev tswj cov dej cov ntsiab lus tiag tiag thaum lub sij hawm tsim khoom thiab tswj cov dej-cement piv rau hauv cov qauv tsim.
3. Thaum qhov zoo ntawm admixtures yog tsawg, ua kom tiav cov kev xav tau txo cov dej yuav tsum tau nce qhov ntau npaum. Kev xyaum qhia tau hais tias kev siv cov khoom siv high-standard admixtures nrog tsawg npaum li cas yog qhov zoo dua li kev siv cov khoom siv qis nrog cov khoom siv siab, txawm hais tias muaj zog ntawm cov pob zeb ua vaj huam sib luag lossis kev tswj cov nqi sib xyaw.
4. Qhov muag tsis pom kev txwv qhov ntau npaum li cas ntawm cov khoom sib xyaw yog unscientific. Qhov no feem ntau ua rau muaj dej ntau ntxiv thiab cov khoom siv cementitious, nce nqi tsim khoom sib xyaw.
5. Qhov tsis muaj kev saib xyuas zoo thiab kev sim tshuaj xyuas qhov sib xyaw ua ke tuaj yeem ua rau muaj qhov tsis zoo ntawm cov khoom sib xyaw ua ke, ua rau muaj kev nce hauv cov ntsiab lus dej thiab muaj kev puas tsuaj loj rau cov pob zeb ua kom muaj zog. Txhim kho qhov zoo saib xyuas ntawm cov khoom sib xyaw yog ncaj qha ntsig txog kev ruaj ntseg thiab lav ntawm pob zeb compressive zog.

Hauv cov ntsiab lus, kev paub txog kev siv cov khoom sib xyaw kom raug tso cai rau kev ua kom muaj zog ntxiv thaum tswj cov nqi tsim khoom sib xyaw lossis txo cov nqi tsim khoom thaum tswj kev ua vaj tse, tsim kom muaj txiaj ntsig zoo thiab kev lag luam rau cov nroj tsuag batching.
