Cov khoom no yog tsim thaum lub sij hawm kev puas tsuaj ntawm pob zeb khib nyiab. Nyob ntawm cov xwm txheej sib sau, cov xuab zeb tuaj yeem yog:

  • alluvial;
  • marine;
  • deuvial;
  • eolian;
  • lake.

Thaum cov khoom tsim tawm thaum lub sijhawm ua haujlwm ntawm cov pas dej thiab cov kwj deg, nws cov ntsiab lus yuav muaj cov duab sib npaug.

Hnub no, yuav luag txhua hom xuab zeb yog siv los ntawm tus txiv neej hauv ntau yam haujlwm thiab kev lag luam. River xuab zeb yog lub tsev sib xyaw ua kemuab rho tawm los ntawm cov dej ntws. Cov khoom siv no muaj kev ua kom huv zoo, uas yog vim li cas tsis muaj pob zeb me me, av nplaum cov ntsiab lus impurities thiab txawv teb chaws suav nrog hauv cov qauv.

Quarry xuab zeb tau muab tshem tawm los ntawm kev ntxuav nrog dej hauv qhov ntim loj, vim li ntawd, nws muaj peev xwm tshem tau cov hmoov av ntawm cov av nplaum. Xav txog cov hom xuab zeb, koj tuaj yeem pom cov xuab zeb zeb, uas yog ntxuav thaum lub sij hawm rho tawm los ntawm cov feem loj ntawm cov pob zeb. Cov khoom no yog dav heev nyob rau hauv kev tsim cov mortars mus rau nteg lub hauv paus thiab kev siv ntawm plastering. Koj tseem tuaj yeem pom cov pob zeb pob zeb hauv av asph alt sib tov.

Kev tsim cov xuab zeb yuav tsum ua raws li GOST 8736-2014, raws li cov khoom siv yog xoob inorganic sib xyaw ntawm cov nplej ntxhib, qhov loj ntawm qhov ncav cuag 5 hli. Qhov ceev ntawm cov khoom yog 1300 kg / m 3. Lub tsev xuab zeb yog tsim thaum lub ntuj puas tsuaj ntawm pob zeb, nws yog mined los ntawm txoj kev tsim cov xuab zeb-gravel thiab xuab zeb deposits tsis muaj thiab siv cov khoom enrichment.

Cov hom xuab zeb tseem ceeb kuj suav nrog cov xuab zeb hnyav hnyav, uas muaj qhov sib xyaw xoob uas tau los ntawm kev sib tsoo ntawm cov pob zeb, ntawm cov tom kawg yuav tsum tau qhia:

  • slag;
  • granites;
  • limestone;
  • marble;
  • pumice;
  • tug.

Ntawm cov xuab zeb dag

Lawv tuaj yeem muaj qhov sib txawv thiab qhov ntom ntom. Yog hais tias peb piv cov nplej ntawm ib tug muabxuab zeb nrog cov nplej ntawm lub hauv paus chiv keeb, lub qub yog txawv los ntawm ib tug mob-angled duab thiab ib tug ntxhib nto. Artificial sands feem ntau yog siv los ua cov sib xyaw ua ke hauv kev npaj cov plasters thiab cov khoom siv zoo nkauj. Raws li qhov tshwm sim, nws tuaj yeem ua tiav qhov kev ntxhib los mos ntawm cov txheej txheem saum toj kawg nkaus ntawm qhov chaw sab nrauv.

Cov khoom siv no tuaj yeem dhau los ua ib feem ntawm txhua txheej ntawm plaster, vim tias feem ntawm cov nplej tuaj yeem sib txawv, nyob ntawm seb hom mortar. Feem ntau cov nplej loj yog suav tias yog sib npaug ntawm qhov loj ntawm cov xuab zeb ntuj. Hauv kev tsim cov xuab zeb dag, hlawv cov thee, pob zeb, nrog rau cov khoom tsis muaj hluav taws kub, uas cov ntsiab lus sulfur tsawg, raug coj los ua.

Cov yam ntxwv ntawm cov khoom siv yuav nyob ntawm qhov zoo ntawm txheej txheej. Nyob rau hauv kev tsim cov hniav plaster los ntawm xws li xuab zeb, crushed pob zeb, hmoov ntawm no pob zeb los yog crumb yuav ntxiv tau ntxiv kom txuag tau nyiaj, nws txawm tau txais txiaj ntsig los ntawm qhov zoo ntawm qhov kev ntxhib los mos.

Hiav txwv xuab zeb tuaj yeem siv rau hauv kev tsim cov vaj tsev sib xyaw, tsim cov khoom sib xyaw ua ke, kev ua haujlwm ntawm plaster, nteg txoj kev hauv paus, kev tsim cov laj kab thiab thaiv, ua cov khoom siv rau lub tsev grouts thiab dyes. Kev tsim cov xuab zeb no yog tswj hwm los ntawm GOST 8736-93.

Fractions tuaj yeem sib txawv ntawm 2.5 txog 3.5 Mk, uas txiav txim siab qhov me me module. Grain ceev yog sib npaug li qhov txwv ntawm 2 mus rau 2.8 g / cm3. Lub hiav txwv xuab zeb yuav tsum tsis muaj cov khoom txawv teb chaws kiag li.impurities, tab sis nyob rau hauv qee feem koj tuaj yeem pom cov ntsiab lus me me ntawm av nplaum thiab hmoov av. Hiav txwv xuab zeb yog tus cwj pwm los ntawm kev siv zog ntawm kev tsim khoom, uas ua rau nws cov nqi siab dua li cov xuab zeb quarry alluvial.

Lub ntsiab feature ntawm quarry xuab zeb yog qhov tsis muaj impurities thiab zaus. Alluvial quarry khoom muaj cov yam ntxwv hauv qab no: feem ntawm 1.5 mus rau 5 hli, qhov ntom sib npaug li 1.60 g / cm 3, nrog rau cov av nplaum, hmoov av thiab lwm yam impurities. Cov tom kawg hauv qhov muaj pes tsawg leeg yuav tsum tsis txhob ntau tshaj 0.03%.

Quarry xuab zeb, tus nqi ntawm ib lub cubic meter yuav yog 2200 rubles, yog siv tsis tau tsuas yog nyob rau hauv kev tsim kho, tab sis kuj nyob rau hauv kho kom zoo nkauj, raws li zoo raws li lub teb chaws kev khwv nyiaj txiag. Tshwj xeeb tshaj yog muaj txiaj ntsig yog kev siv cov xuab zeb hauv kev tsim cov pob zeb thiab cib, nrog rau hauv kev tsim kho thiab vaj tsev.

Khaub thuas xuab zeb, tus nqi yuav yog 2300 rubles, tuaj yeem nthuav tawm hauv daim ntawv ntawm cov khoom siv nrog ib feem ntawm 2.5 txog 2.7 hli. Hauv kev tsim cov pob zeb uas muaj zog thiab cov pob zeb muaj zog, cov xuab zeb ntxhib feem ntau yog siv. Cov khoom siv hauv av mus rau masonry thiab paving slabs.

Alluvial dej xuab zeb muaj qhov ntom ntawm 1.5 kg / m 3. Yog tias peb tab tom tham txog qhov ntom ntom hauv lub xeev ntawm cov av noo, ces daim duab no yuav raug txo mus rau 1.45.tej zaum yuav muaj cov hmoov av, av nplaum thiab av nplaum, tab sis tsis ntau tshaj 0.7% los ntawm qhov hnyav. Cov dej noo ntawm cov khoom yog 4% thaum lub ntiajteb txawj nqus yog 2.6g / cm 3. Cov xuab zeb no yog mined siv lub dredger, uas yog tsau rau ntawm lub nkoj. Cov cuab yeej zoo li no tau ntxiv nrog kev teeb tsa hydromechanical, lub twj tso kua mis muaj zog, cov tes hauj lwm thiab cov tso tsheb hlau luam rau kev faib cov khoom los ntawm kev sib xyaw. Extracting xuab zeb los ntawm cov dej qhuav yog zoo li extracting xuab zeb.

Zaj lus

Yuav luag txhua hom xuab zeb tuaj yeem raug ntaus nqi rau thawj chav kawm ntawm radioactivity. Qhov tsuas yog kev zam yog crushed xuab zeb. Yog tias peb tham txog lwm yam, ces lawv muaj hluav taws xob muaj kev nyab xeeb thiab tuaj yeem siv rau hauv txhua qhov kev tsim kho yam tsis muaj kev txwv.

Kev siv cov xuab zeb yog ib txwm niaj hnub no. Piv txwv li, nws cov quartz ntau yam yog siv los tsim cov khoom siv vuam siv rau kev siv dav thiab tshwj xeeb. Raws li kev tsim kho ntau yam, nws yog siv kom tau cov txheej txheem txheej txheem los ntawm kev sib xyaw nrog dyes. Sands kuj tau siv thaum lub sijhawm ua haujlwm tiav, nrog rau kev kho qhov chaw. Cov khoom siv kuj ua ib feem ntawm asph alt pob zeb sib tov, uas yog siv rau hauv kev tso txoj kev thiab hauv kev tsim kho.
