Kev tsim cov asph alt loj hauv thaj chaw ntawm Lavxias Federation tau ua txij li xyoo 2013. Xyoo no, nws tau txiav txim siab los tsim ntau txoj haujlwm tseemfwv, uas suav nrog kev tsim kho txoj kev tshiab, nrog rau kev kho cov kev loj qub.

Kev piav qhia dav dav

Ib yam khoom xws li asph alt yog siv ntau zaus, tshwj xeeb tshaj yog niaj hnub no. Nrog nws cov kev pab, yuav luag txhua txoj kev tsim, uas tuaj yeem yog tsoomfwv txoj kev loj ntawm cov nroog, lossis cov kev ntiag tug me hauv lub vaj. Rau kev npaj ntawm ob qho kev xaiv, tib qhov sib tov yog siv. Yog tias peb tham txog cov ntsiab lus dav dav ntawm cov tshuaj no, ces nws suav nrog ntau lub ntsiab lus. Bitumen yuav ua raws li kev khi rau cov khoom no.

Hauv kev tsim cov asph alt, cov khoom siv raw xws li xuab zeb thiab qee cov ntxhia pob zeb tsis tuaj yeem muab xa nrog. Lub caij thib peb thiab zaum kawg yuav yog cov additives, kuj ua los ntawm cov zaub mov los yog hluavtaws.

Raw khoom rau asph alt

Nws yuav tsum tau muab sau tseg tias cov khoom no yuavua ob hom. Muaj asph alt ntawm natural keeb kwm thiab artificially tsim. Yog hais tias peb tham txog lub ntuj daim ntawv ntawm cov khoom no, ces nws los ntawm hnyav roj residues. Cov khoom no yog cov khoom siv dub refractory.

Hauv kev tsim cov asph alt, cov khoom siv feem ntau yog cov khoom siv tawv thiab xoob, xws li xuab zeb, pob zeb, limestone. Nqus khi cov ntsiab lus ntxiv rau lawv, uas tuaj yeem yog bitumen lossis tar.

Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias txhawm rau kom tau txais cov pob zeb asph alt sib tov, nws tsis txaus tsuas yog sib tov tag nrho cov ntsiab lus no. Txhawm rau ua kom cov tshuaj nyuaj txaus, nws yog compacted thiab dov tawm nrog ib tug roller. Tom qab dhau los ntawm cov txheej txheem no, cov khoom muaj zog zoo li lub pob zeb, thiab muaj peev xwm tiv taus kev ntxhov siab loj heev.

piav qhia dav dav ntawm asph alt hom

Nyob hauv kev tsim cov asph alt, ib qho ntawm cov haujlwm tseem ceeb tshaj plaws uas cov chaw tsim khoom ntsib yog kev ua raws txhua qhov kev faib ua feem nrog qhov raug siab heev. Yog hais tias nws tshwm sim hais tias muaj ntau viscous tshuaj los yog xoob minerals, ces lub resulting txheej yuav tsis muaj peev xwm tiv taus siab loads. Nws yuav tawg nyob rau hauv kev cuam tshuam ntawm yam xws li kub hloov pauv, av noo siab.

Nws tseem tsim nyog hais tias hom asph alt thiab nws cov khoom siv sib txawv tuaj yeem sib txawv heev nyob ntawm seb qhov chaw twg yuav tsum tau pw. Hauv lwm lo lus, kev nyab xeeb ntawm thaj chaw ua si lub luag haujlwm tseem ceeb.

Hnub no, muaj ntau yam sib txawv ntawm cov khoom siv raw. Qhov yooj yim tshaj plaws thiab pheej yig tshaj rau kev tsim khoom yog xuab zeb. Cov muaj pes tsawg leeg ntawm cov khoom no yog heev yooj yim - xuab zeb thiab bitumen. Yog hais tias crushed pob zeb thiab me ntsis ntxhia hmoov ntxiv rau qhov muaj pes tsawg leeg, ces cov zis yuav yog lub pob zeb crushed hom txheej. Raws li kev siv thev naus laus zis ntawm asph alt ntau lawm, txhua yam yuav hloov pauv - los ntawm nws cov yam ntxwv thiab qhov chaw ntawm daim ntawv thov mus rau tus nqi.

Muaj peb pawg ntawm cov khoom siv asph alt pob zeb. Qhov sib txawv ntawm cov pawg no nyob rau hauv qhov kub thiab txias ntawm cov khoom xws li bitumen melted. Peb pawg tseem ceeb yog kub, sov thiab txias asph alt. Qhov txawv kuj yog nyob rau hauv qhov kub thiab txias ntawm qhov chaw ua hauj lwm ntawm nteg tawm txoj kev tshiab nto.

• thawj hom yog kub tso cov khoom. Raws li ib feem ntawm xws li ib tug sib tov yog bitumen, uas melted ntawm kub heev, thiab yog li ntawd rau nws nteg nws yog tsim nyog los cua sov asph alt mus txog 120 degrees Celsius thiab saum toj no. Feem ntau, cov khoom siv los tsim txoj kev loj tshiab.
• hom thib ob yog sov styling. Cov tshuaj muaj pes tsawg leeg muaj xws li tsawg-viscosity bitumen, uas yuav tsum tau rhuab mus rau ib tug ntsuas ntawm 40-80 degrees Celsius.
• hom kawg yog asph alt txias, lossis txias paving. Qhov sib xyaw ntawm cov khoom sib xyaw suav nrog ib qho tshwj xeeb bituminous puag, uas tuaj yeem siv tau yog tias huab cua kub tsis qis dua 10 degrees Celsius. Qhov kev xaiv no yog siv feem ntau. Qhov lojdaim ntaub ntawv yog kho lem, patching qhov los yog potholes nyob rau hauv lub pavement uas twb muaj lawm.

Tsim tawm hauv tsev

Nws yog ntuj uas cov nroj tsuag asph alt koom nrog kev tsim khoom. Tsuas muaj ob hom kev lag luam no. Qhov sib txawv ntawm lawv yog nyob rau hauv cov txheej txheem ntawm kev tsim cov khoom. Muaj cov chaw ua haujlwm cyclic lossis txuas ntxiv mus.

thawj qeb ntawm cov nroj tsuag feem ntau yog tsim nyob ze cov nroog loj, qhov chaw asph alt yog qhov xav tau tas li, tab sis tsis yog ntau dhau. Ib qho tshwj xeeb ntawm hom kev lag luam no yog tias nws muaj peev xwm hloov tau hom mortar tsim ob peb zaug hauv ib qho kev hloov. Nws tseem ceeb heev uas yuav tsum nco ntsoov tias qhov no tsis cuam tshuam qhov zoo ntawm cov khoom tsim.

Cyclic Enterprise

Hom asph alt cog no yog nruab nrog cov khoom siv yooj yim tshaj plaws tab sis siv tau zoo tshaj plaws. Muaj cov chav tau txais cov khib nyiab, ib qho chaw khaws cov khoom tiav, nrog rau asph alt mixing cog. Ntxiv rau qhov tseem ceeb hauv kev tsim khoom, kuj tseem yuav muaj qee yam khoom siv tshwj xeeb ntxiv. Nws tuaj yeem yog ntauwd, ib qho screen, crushing thiab tshuaj ntsuam vibrating sieve siv los tshuaj xyuas cov khoom siv pob zeb. Tsis tas li ntawd, kev siv cov cuab yeej zoo li no ua rau lub vijtsam txhim kho qhov ua tau zoo ntawm asph alt vim qhov tseeb tias tag nrho cov khoom siv ntau tau muab faib ua feem ntau txawm tias ua ntej lawv nkag mus rau hauv qhov sib tov.

Los ntawm qhov tsis zoo ntawm kev lag luam zoo li no, ib tus tuaj yeem tawm qhov tseeb tiasnws tsim cov khoom siv me me ntawm txoj kev. Tsis tas li ntawd, nws yog kiag li nyob ruaj ruaj vim muaj cov units xws li ib tug pej thuam thiab ib qho screen. Tus nqi ntawm asph alt yuav siab dua qhov kev tsim khoom tas mus li.

Qhov txiaj ntsig tseem ceeb ntawm cov nroj tsuag tsis tu ncua yog tias nws tsuas muaj cov cuab yeej tsim nyog tshaj plaws los ua nws cov haujlwm. Qhov no tso cai rau koj txav mus tas li.

Ib txwm, qhov txiaj ntsig thib ob ntawm qhov kev lag luam no yog cov txheej txheem tsim khoom tas li, ua tsaug uas nws tuaj yeem tau txais ntau cov asph alt. Tag nrho cov khoom tsim nyog yog tas li muab rau lub bunker rau cua sov. Muaj cov txheej txheem tseem ceeb tshwm sim, thiab cov zis twb tau npaj ua asph alt. Los ntawm lub bunker, cov khoom yog pauv mus rau lub cia silo. Nyob rau hauv cov chaw zoo li no, koj tuaj yeem ua kom kub ntawm cov khoom mus txog plaub hnub.

Ntawm qhov tsis zoo ntawm kev tsim khoom, nws sawv tawm tias tsis muaj suab nrov, uas txhais tau hais tias cov khoom xyaw tsis sieved. Yog tsis muaj cov txheej txheem no ua rau cov khoom ntawm cov khoom kawg, vim tias feem ntau yuav cov khoom siv raw, cov khoom ntxhia tsis tau raws li cov qauv thiab muaj cov impurities. Lub ingress ntawm xws li cov khoom tsis tsim nyog rau hauv qhov sib tov thiab txo cov durability ntawm txheej.

Tus nqi ntawm asph alt nyob ntawm qhov zoo ntawm nws qhov kev npaj. Tus nqi pib los ntawm kwv yees li 600 rubles ib tuj thiab tuaj yeem ncav cuag 3,000 rubles rau tib lub ntim.
