Tam sim no, rau ntau yam haujlwm tsim kho, suav nrog kev tso, ntau yam pob zeb tau siv. Ntau tus ntawm lawv muaj cov yam ntxwv tseem ceeb, lawv tuaj yeem yooj yim zam qib siab ntawm cov av noo, kev nyuab siab hauv tshuab, qhov kub tshaj. Cov nyom nyom tau txais ntau thiab ntau dua qhov muaj koob npe. Koj yuav tsum paub txog cov yam ntxwv tseem ceeb ntawm cov khoom no, nrog rau txog thaj chaw uas nws feem ntau siv.
Nws yog dab tsi?
Dresva yog pob zeb tshwj xeeb, uas yog rau ntau yam sedimentary. Nws zoo li cov ntxhia yooj yim muaj pes tsawg leeg tsim los ntawm kev siv tshuab puas ntawm pob zeb.
Dresva tuaj yeem tsim nyob rau hauv qhov cuam tshuam ntawm kev hloov pauv kub, hnyav nag lossis daus. Cov khoom tuaj yeem tsim ob qho tib si hauv ib puag ncig ntuj thiab nrog kev ua tshwj xeeb ntawm pob zeb. Cov nyiaj tso los ntawm ntuj, raws li txoj cai, tau muab pov tseg. Ntawm ntu geological, lawv yuav raug faus.
- Cov txheej sab saud yog cov av uas muaj pob zeb me me uas zoo ib yam li cov xuab zeb zoo ib yam.
- Cov txheej qis suav nrog cov ntsiab lus loj dua. Ntawm lub hauv paus, raws li txoj cai, muaj cov pob zeb tawg thiab cov pob zeb tawg.
Cov pob zeb no tau txais ntau zaus los ntawm cov khoom sib luag, nrog rau cov khoom siv granite thiab pegmatite. Hauv cov txheej txheem ntawm kev tsim cov nyom, nws cov khoom tau txais cov qauv ntxeem tau. Tab sis tib lub sijhawm, nruab nrab tseem ruaj khov li sai tau . Cov khoom siv pheej yig thiab pheej yig no tau siv ntau yam kev tsim kho.
Tus nqi ntawm cov ntaub ntawv tuaj yeem sib txawv ntau yam . Nws yuav vam khom feem ntau ntawm cov khoom tshwj xeeb ntawm cov ntaub ntawv raw thiab ntawm txoj hauv kev tsuas. Qhov nyuaj dua cov txheej txheem ntawm kev tshem cov khoom los ntawm cov chaw txua txiag zeb, thiab qhov ua kom ntev dua lawv ua, cov nqi rau lawv yuav ntau dua. Nws yuav tsum tau sau tseg tias nyob rau hauv txhua rooj plaub, tus nqi ntawm cov pob zeb yuav qis dua me ntsis piv rau cov pob zeb tawg.
Qhov nruab nrab, niaj hnub no nws yog kwv yees li 200-230 rubles rau 1 m3.
Yam ntxwv thiab khoom
Ntawm qhov tseem ceeb tshaj plaws ntawm tus tsiaj yog cov hauv qab no:
- qib siab zog;
- dej tsis kam;
- muaj peev xwm nce;
- porosity ntawm tus qauv;
- nyiam mus rau huab cua;
- heterogeneous complex muaj pes tsawg leeg;
- xim av-xim av.
Ib qho ntxiv, cov pob zeb muaj qee yam khoom tseem ceeb
- Kev lim dej siab (ntsuas ntawm dej tsis kam). Tus nqi nce ntau dua 100 m 3 / hnub.
- Cov dej noo tsawg. Gruss yuav luag tsis nqus dej noo vim nws cov txheej txheem sab hauv ntau dhau.
- Tus txheeb ze siab ceev. Tus nqi no feem ntau nyob ntawm qhov tob ntawm qhov tshwm sim. Feem ntau, qhov ceev yog kwv yees li 1800 kg lossis ntau dua ib m3. Qhov sib piv sib piv (qhia tau hais tias cov khoom yuav ntom npaum li cas tom qab ramming) tuaj yeem sib txawv me ntsis, tab sis feem ntau nws tus nqi yog 1, 1-1, 3.
- Zoo sib xws loj. Qhov hnyav ntawm cov pob zeb zoo li no yuav ncav cuag me ntsis ntau dua 2 tons ib cubic meter. Tus nqi no hu ua qhov nqus tshwj xeeb ntawm cov khoom.
Nws yuav tsum tau nco ntsoov tias tus tsiaj no tsis muaj qhov ua tau zoo. Ib qho ntxiv, nws yuav tsum tsis txhob siv los ua cov khoom siv sab nraum zoov vim nws ua tsis tau zoo rau ntau yam huab cua.
Cov pob zeb no tau tsim los ntawm cov khoom me me, txoj kab uas hla tuaj yeem tsis pub dhau 3-5 hli . Nyob rau tib lub sijhawm, cov khoom uas tsis yog kuav los tiag uas muaj qhov loj me tau hu ua grit lossis tsuas yog cov pob zeb me me. Txhawm rau txhawm rau txiav txim siab ntau dua tus yam ntxwv tseem ceeb ntawm cov pob zeb uas tau khawb ntawm cov nyiaj tshwj xeeb, nws raug xa mus rau kev kawm tshwj xeeb hauv chav kuaj.
Txhua qhov tsis tseem ceeb thiab cov khoom uas cuam tshuam nrog gruss tuaj yeem nrhiav tau yooj yim hauv GOST 8267-93.
Cov ntawv thov
Dresva tuaj yeem siv tau hauv ntau thaj chaw
- Feem ntau nws yog hom tsiaj no uas tau coj los rau qhov raug tso ntawm paving slabs . Hauv qhov no, cov khoom siv yuav tsum tau sib xyaw ua ke nrog cov pob zeb thiab cov pob zeb tawg. Xws li kev sib xyaw ua ke, thaum kho, muaj qib xav tau ntawm lub zog. Nws yuav tso cai rau koj ua kom muaj kev ntseeg siab tshaj plaws thiab ruaj khov pobzeb tso.
- Thiab tseem cov khoom siv ntuj no tuaj yeem siv los tsim lub hauv paus ruaj khov . Hauv qhov no, cov nyom tau ntxiv rau cov cement slurry. Xws li kev tiv thaiv ntxiv yuav ua rau cov qauv ruaj khov thiab muaj zog dua.
- Ib qho ntxiv, cov khoom siv feem ntau tau yuav los txhawm rau txhawm rau txhaws ntawm lub hauv paus uas npaj tau . Cov khoom yuav yog qhov kev xaiv zoo tshaj plaws rau lub hom phiaj no, vim nws muaj dej tsis kam thiab lwm yam yam ntxwv tseem ceeb. Txij li cov pob zeb muaj tus nqi qis, kev ua yuav pheej yig li sai tau.
- Qee zaum cov khoom sib xyaw ua ke no tau txais los ua kom nce qib thiab nce qib thaj chaw . Qhov no yog ua tiav siv cov ntawv rov ua dua, uas tau ua tiav ua ntej pib ua haujlwm pib, lossis thaum kawg. Hauv thawj kis, saum npoo av yog qib txhawm rau txhawm rau txhawm rau nkag mus rau ntau yam khoom ntawm lub xaib. Nws tseem yuav ua kom muaj chaw nres tsheb ib ntus.
Hauv qhov xwm txheej thib ob, cov khoom sib xyaw ua ke tau siv los thawb cov nqaj thiab cov av tsim tom qab ua haujlwm. Grit tuaj yeem ua lub hauv paus zoo rau kev tsim lub tsev pheeb suab, uas tom qab ntawd yuav tau ntim nrog cov tshuaj cement lossis asphalt . Cov av no tseem tuaj yeem tsim nyog rau thaj av uas tom qab ntawd yuav siv rau hauv vaj lossis vaj thiab zaub zaub. Ntau yam khoom siv hauv tsev tuaj yeem teeb tsa rau ntawm qhov chaw zoo li no.
Yog tias koj xav tau nce qib ntawm lub xaib, tom qab ntawd koj yuav tsum tsim cov txheej tuab tuab ntawm cov khoom siv, thiab tom qab ntawd ua tib zoo saib xyuas thiab ua kom nruj tamping li sai tau . Nws yuav tsim qhov me me ntawm pob zeb, yog li nws yuav tsis tsim nyog ntxiv cov muaj pes tsawg leeg nyob rau lub sijhawm.
Yog tias koj xav tau nce cov av mus rau qhov siab siab lossis tsuas yog ntxiv dag zog rau nws, tom qab ntawd koj tseem tuaj yeem siv cov khoom siv pob zeb no, tab sis tseem ntau zaus lawv siv pob zeb tshwj xeeb muaj pes tsawg leeg.
- Grit tuaj yeem tsim nyog rau fertilizing ntau yam nroj tsuag, vim nws muaj cov qauv ntxeem tau thiab hloov pauv los ntawm kev ua cov pob zeb. Xws li cov khoom muaj nyob hauv lawv cov muaj pes tsawg tus ntawm cov khoom noj muaj txiaj ntsig thiab muaj txiaj ntsig zoo, cov zaub mov, nws yog lawv uas ua raws li cov chiv rau vaj thaj av. Qee lub sij hawm me me tsis tau cog ntoo thiab cov nyom tau cog rau ntawm cov hauv paus tsim los ntawm gruss. Tab sis qhov no tsuas tuaj yeem ua tiav ntawm kev sib xyaw nrog cov organic tsis huv, txwv tsis pub koj yuav tsum tau txheej txheej ntawm cov av dub lossis cov av tshwj xeeb cog rau saum. Hauv cov txheej txheem ntawm kev rhuav tshem pob zeb tas mus li, kev sib xyaw ua ke yuav cuam tshuam tas li nrog cov av thiab saturate nws, nws ua rau thaj av muaj av ntau dua, thiab tseem tso cai rau koj nce qib ntawm kev tsim khoom thiab muaj sia nyob ntawm cov zaub tshiab.
- Dresva tau nquag siv hauv kev tawm tsam dej khov thaum lub caij ntuj no. Txog cov hom phiaj no, cov khoom siv ib puag ncig zoo ib puag ncig yuav tsum ua kom tsawg li sai tau. Cov khoom me me muaj cov khoom zoo heev.
- Sedimentary pob zeb qee zaum siv los npaj lub hauv paus rau cov cement. Hauv qhov no, kev sib xyaw yuav tsum tau ua kom zoo nrog kev sib tsoo. Thaum ntxiv cov tshuaj reagents rau huab hwm coj, cov kua qaub zoo tuaj yeem tau txais.
- Dresva yuav yog qhov kev xaiv zoo tshaj plaws rau kev tsim cov txheej txheem dej ntws. Tom qab tag nrho, nws khav theeb muaj peev xwm ya raws qis, xws li kev sib xyaw yuav tsis nqus dej.
- Ntau zuj zus, lawv tau pov tseg txoj hauv kev, cov av los ntawm cov tsiaj no, thiab kev ua haujlwm tau ua tiav nrog nws txoj kev pab. Thaum thaj chaw tsim kho av, cov av me me yuav yog qhov kev xaiv zoo, lawv yuav ua rau nws tuaj yeem rov ua tau thaj av, tsim qhov chaw rov qab rau tom tshav puam thiab txoj kev taug kev. Tab sis tib lub sijhawm, thaum tsim cov txheej txheem txhim khu kev qha, suav nrog cov tsev nyob, nws tsis tuaj yeem siv cov khoom siv ntawd, vim nws tsis muaj qib xav tau ntawm lub zog thiab tsis tuaj yeem muab kev ntseeg tau txaus.
