Cov khoom siv hauv tsev xws li sib tsoo pob zeb-xuab zeb sib xyaw yog cov khoom tsim los ntawm cov khoom siv ntuj tsim. Ib qho ntxiv, nws tuaj yeem tsim los ntawm huab cua ntawm pob zeb. Qhov tseeb, nws yog kev sib xyaw ntawm cov xuab zeb thiab cov pob zeb tawg, siv dav hauv kev tsim kho.

Cov yam ntxwv dav dav

Feem ntau, cov khoom siv hauv tsev yog pov tseg ntawm granite thiab limestone tsim thaum lub sijhawm rho tawm thiab ua cov pob zeb, uas muaj cov tawg ntawm cov pob zeb tawg thiab cov pob zeb txua zeb.

Thaum crushing nyob rau hauv ib tsob nroj sorting, qhov sib tov yog sieved , txhawm rau txhawm rau ua haujlwm ib feem, ntxuav los ntawm cov khoom me me, vim li ntawd, ntau hom khoom siv hauv tsev tau txais raws qhov loj ntawm cov nplej ntawm cov pob zeb tawg.

Yog tias muaj pes tsawg leeg muaj 4 lossis ntau dua feem pua ntawm av nplaum thiab hmoov av, cov khoom lag luam tsis tuaj yeem ua tau raws li tus qauv ntawm GOST 25607-94. Ib qho ntxiv, nws yuav tsum tau hais tias cov keeb kwm hluav taws xob nyob hauv thaj tsam 300 Bq / kg, uas suav tias yog kev nyab xeeb thiab tso cai siv cov khoom sib xyaw los tsim cov tsev nyob.

Cov yam ntxwv tseem ceeb yuav tsum paub txog thaum teeb tsa thiab thauj:

• ntim qhov hnyav;
• tej ceev.

Nws hloov tawm tias tsis yog tsuas yog cov sib xyaw ua ke yog qhov tseem ceeb, tab sis kuj yog qhov ntom ntom ntom ntom, uas yog, kev sib zog ua kom sib tsoo ntawm cov pob zeb tawg, uas yog tus yam ntxwv hloov pauv hauv nws ntim thaum ramming, nrog rau kev nqaim thiab kev thauj mus los. Ib qho ntawm qhov xav tau feem ntau qhov ntau thiab tsawg - 20-40 mm, yog C6 sib xyaw nrog qhov ntom ntom ntom ntawm 1.35 t / m3. Nrog ib feem loj dua, qhov tamping tsis ua haujlwm zoo.

Cov duab ntawm cov nplej kuj tseem ua lub luag haujlwm, nyiam dua thaum nws yog cuboid. Qhov tseeb, cov ntsuas no txiav txim siab qhov zoo ntawm cov khoom siv hauv tsev. Yog tias koj tsis quav ntsej nws, nws tsis tuaj yeem ua tiav cov yam ntxwv ua tau zoo ntawm txoj kev saum npoo av, rau qhov uas, feem ntau, siv cov pob zeb tawg-xuab zeb sib xyaw.

Cov txiaj ntsig ntawm kev sib xyaw dawb-ntws

Crushed-zeb-xuab zeb sib xyaw ntawm ntau hom yog cov khoom siv ruaj khov uas ua rau nws siv tau rau kev ua haujlwm sab nraum zoov.

Qhov zoo tshaj:

• muaj peev xwm nqus dej ua pa;
• tiv taus cov av noo siab;
• tiv thaiv kom sov qis;
• chav kawm muaj kev nyab xeeb ntawm hluav taws xob;

• lub zog, hnav tsis kam nyob rau hauv siab load;
• kev pom zoo lim dej pom coefficient hauv txheej rau ntau lub hom phiaj;
• muaj pes tsawg leeg ntawm cov pob zeb tawg thiab xuab zeb.

Cov no yog cov khoom lag luam tseem ceeb ntawm cov khoom lag luam, uas, ntxiv rau, tseem ceeb rau lawv cov nqi qis.

Hom khoom

Cov pob zeb tawg-xuab zeb sib xyaw, ua cov khoom ntawm kev zom, muaj cov nplej ntawm qhov sib txawv, uas txiav txim siab nws cov feem. Qhov dav ntawm kev thov cov khoom siv nyob ntawm qhov ntsuas no.

SCHPS C1 - qhov sib xyaw ua kom muaj qhov loj me ntawm 40 mm. Qhov tseeb, cov khoom tuaj yeem suav nrog cov feem me me ntawm 5 txog 10 hli, uas nyob hauv feem ntau ntawm cov ntim, qhov loj tshaj tam sim no muaj nyob hauv 10% ntawm tag nrho, 10% ntawm cov hmoov av zoo li microparticles kuj tseem tso cai hauv kev sib xyaw. Lub hauv paus tseem ceeb ntawm kev thov C1 sib xyaw yog kev teeb tsa ntawm txoj hauv kev, tshwj xeeb, thaum nws xav tau kom tau txais lub tiaj tiaj, du. Txawm tias txoj hauv kev tsis muaj txheej txheem tuaj yeem tsim kho nrog kev pab ntawm cov khoom siv. Cov no feem ntau yog tshav dav hlau tsaws tsag.

Sib tov C2 muaj lub zog siab zog, nws muaj cov pob zeb tawg nrog cov khoom tiv taus te (F100 lossis F300). Qhov loj tshaj plaws ntawm cov nplej suav nrog hauv kev sib xyaw yog 20 hli, thiab lub hauv paus yog cov feem me me uas muaj qhov loj me txog 10 hli. Av thiab hmoov av tsuas yog 5%. Cov khoom muaj nws qhov zoo, suav nrog kev muaj peev xwm nteg tau hauv txhua qhov huab cua thiab huab cua sov.

Cov txheej uas tau txais nrog cov khoom no tsis ntshai ya raws, txias, thiab tsis ua rau tawg thaum ua haujlwm. Nws tuaj yeem siv ob qho tib si rau kev tsim txheej txheej ntawm I-III pawg, thiab rau kev tsim kho av hauv thaj chaw ntiag tug, vim nws tus nqi pheej yig.

Khoom C3 sib txawv hauv cov granules loj tshaj plaws nrog qhov loj ntawm 120 mm. Nws cov Cheebtsam yog crushed granite thiab zeb zeb, thaum hmoov av thiab av nplaum raws li GOST tsis pub tshaj 4%. Qhov no yog cov khoom siv ruaj khov, tiv taus cua sov, kev teeb tsa uas yooj yim dua thiab yooj yim dua piv rau lwm hom SchPS. Lub hom phiaj tseem ceeb - txheej ntxiv ntawm txoj kev saum npoo av, ua rau nws muaj peev xwm txo tus nqi ntawm cov ntaub ntawv xws li asphalt, qhob.

Kev faib ua feem ntawm cov pob zeb muaj qhov ua tau zoo, vim li no cov txheej txheej tiv taus kom cov khoom hnyav nce.

• SCHPS C4 suav nrog sifted cov chaw txua txiag zeb xuab zeb thiab cov pob zeb tawg ua ke nrog ib feem ntawm 80 hli. Kev sib xyaw yog siv rau kev tsim vaj tsev, txij li cov ntsuas hluav taws xob ntawm cov khoom tsis tshaj 300 Bq / kg. Qhov no yog cov khoom siv zoo, yooj yim rau kev khaws thiab thauj, koj tuaj yeem ua haujlwm nrog nws hauv txhua qhov xwm txheej huab cua. Nws yog siv los tsim txoj hauv kev, ballast prism ntawm txoj kev tsheb ciav hlau thiab tramways, thiab ntxiv dag zog rau txoj kev xub pwg.
• Sib C5 muaj feem ntawm 40 txog 80 hli. Qhov no yog cov khoom lag luam muaj txiaj ntsig zoo hauv qhov xav tau ntau, lub ntim loj uas tau ua los ntawm 40-60 mm hais nrog cov hmoov av zoo li cov tshuaj ntxiv tsis tshaj 4%. Kev siv ntawm cov khoom lag luam zoo ib yam li kev siv C4, nws kuj tseem siv rau hauv kev tsim cov tsev nyob thiab cov tsev tsim khoom, txoj kev hauv av, rau kev ua haujlwm pob zeb, raws li txhawb cov txheej txheem ntawm txoj kev.

Thaj chaw ntawm kev thov sib xyaw C4 thiab C5 yog qhov dav dua, lawv suav tias yog cov ntaub ntawv xav tau tshaj plaws.

Crushed-zeb-zeb muaj pes tsawg leeg С6 txawv los ntawm lwm qhov sib xyaw ua ke pub dawb hauv kev pom kev sib cog nrog cov menyuam, khaws cia ntev, muaj peev xwm ua haujlwm ntawm qhov kub thiab txias thiab hauv huab cua sib txawv. Lub hauv paus ntawm cov khoom siv yog granite feem ntawm 5 txog 20 thiab 20-40 hli. Nws yog siv nyob rau yuav luag txhua qhov chaw ntawm kev tsim kho. Tom qab kev teeb tsa, kev txav mus los ntawm qhov tsim tau tso cai yuav luag tam sim. Cov khoom sib xyaw muaj tus nqi qis, ua tsaug uas muaj lub sijhawm los cawm ntawm asphalt thiab pob zeb ua vaj.

• Khoom C7 thiab C8 feem ntau yog ua haujlwm thaum tso txheej txheej qis ntawm txoj kev loj thiab muaj qhov sib txawv me me - 10 thiab 5 mm. Kev txhawb cov cement ntawm C7 cov khoom ua rau sib tov tiv taus qhov kub thiab tsis suav nrog cov tsos ntawm cov kab nrib pleb ntawm txheej thaum ua haujlwm.
• Sib C9 muaj qhov loj me ntawm 80 mm, ntxiv rau txoj hauv kev, nws tau siv rau kev tsim kho cov chaw nres tsheb, cov xwmfab, kev taug kev thiab txoj kev hauv tebchaws.
• Thaum pib theem ntawm txoj kev tsim kho, nws raug tso cai siv C10 nrog cov ntsiab lus 20 hli , nws muaj txog li 30% ntawm cov xuab zeb zeb zeb thiab 20% av nplaum thiab hmoov av.

Raws li cov yam ntxwv zoo ntawm kev sib zog ntawm cov khoom, qhov xav tau tshaj plaws yog C4 tsoo pob zeb-xuab zeb sib xyaw, uas tseem suav tias yog ze tshaj rau cov zaub mov ntuj hauv nws cov muaj pes tsawg leeg.
