Sand-crushed pob zeb sib tov, uas paub nyob rau hauv cov ntawv luv PSC, muaj 50 feem pua kev tshuaj ntsuam thiab tib tus nqi ntawm cov pob zeb crushed. Hauv qhov no, cov ntsiab lus ntawm cov khoom xyaw kawg lossis pob zeb yuav tsum yog tsawg kawg 15% ntawm tag nrho pawg. Cov khoom no yog tau los ntawm crushing limestone, thiab nws cov natural ntau yam kuj muaj nyob rau ntawm no.
Kev piav qhia dav dav
Sand-gravel sib tov muaj cov yam ntxwv zoo heev thiab tus nqi qis. Ob yam no ua rau cov khoom siv nrov heev hauv kev kho thiab kev tsim kho. Nws yog qhov zoo tshaj plaws rau compacting txheej hauv txoj kev ua haujlwm. Cov muaj pes tsawg leeg yog indispensable rau kev tsim kho ntawm pob zeb, asph alt thiab lwm qhov chaw. Nws dhau los ua ib feem ntawm cov crane khiav. Cov muaj pes tsawg leeg yog dav siv nyob rau hauv ntsuas railway embankments, raws li zoo raws li nyob rau hauv lub tsim ntawm asph alt qhob mixs.
PShS kev faib tawm
Sand-gravel mixtuaj yeem enriched los yog ntuj, thawj ntawm lawv yog tau los ntawm txoj kev ntawm natural enrichment. Ntawm lwm yam, qee pawg ntawm cov ntaub ntawv tuaj yeem paub qhov txawv, ntawm lawv C2, uas txhais tau tias feem ntau txog 20 millimeters. Yog hais tias peb tham txog cov muaj pes tsawg leeg nyob rau hauv lub abbreviation C4 los yog C5, ces koj muaj ib feem ntawm txog li 80 millimeters. Lub npe C6 kuj qhia txog qhov feem ntawm 0 txog 40 millimeters. Ntawm kev muag khoom koj tuaj yeem pom C12, uas txhais tau tias muaj kev suav nrog txog 10 millimeters. Nyob ntawm lub hom phiaj, qhov sib tov tuaj yeem yog cov hauv qab no: rau kev pavement ntawm txoj kev thiab lub hauv paus ntawm airfields, rau ballasting railway embankments thiab rau kev tsim cov asph alt qhob mixs.
Siv gravel-sand
Sand-gravel sib tov, nyob ntawm daim ntawv thov, muaj qee yam zoo. Yog li, crushed pob zeb-xuab zeb siv rau kev loj thiab airfields muaj peev xwm muab lub zog yuav tsum tau rau txheej los yog hauv paus. Ntawm lwm yam, nws yog siv los ntxiv dag zog rau txoj kev lub xub pwg nyom. Xuab zeb, uas yog siv rau ballasting embankments, yog siv nyob rau hauv lub koom haum ntawm railway lem ntawm ntau yam patency thiab kev siv ntawm lub tsheb, uas distinguishes tus thib ob muab tub lim los ntawm yav dhau los ib tug nyob rau hauv uas nws yog npaj rau lub hom phiaj lem. Hauv nws cov khoom siv, kev siv tshuab ntawm crushing serpentinite yog siv. Qhov tshwm sim yuav tsum tsis pub tshaj 25 millimeters loj.
Crushed pob zeb-xuab zeb sib tov (GOST 9128-97, yuav tsum tau soj ntsuam thaumntau lawm) tuaj yeem siv rau kev sib xyaw asph alt thiab yog cov khoom siv uas tau txais hauv cov txheej txheem ntawm crushing pob zeb. Cov muaj pes tsawg leeg yog siv los ua cov ntxhia hauv cov khoom sib xyaw ua ke. Cov khoom tuaj yeem sib txawv ntawm 1 txog 20 millimeters.
Cov txiaj ntsig tseem ceeb
Crushed pob zeb-sand mix C4 feem ntau piv rau cov pob zeb ntshiab. Cov tom kawg poob hauv ntau yam. Ntawm lawv, yuav tsum tau hais txog tus nqi qis dua, zoo heev sealing zoo, nrog rau txoj kev siv yooj yim. Vim lub fact tias cov sib tov piav qhia muaj xuab zeb, crushed pob zeb thiab gravel, zaum kawg cov khoom ntawm cov mixs yog cuam tshuam los ntawm cov yam ntxwv ntawm peb Cheebtsam ib zaug. Qhov tseem ceeb tshwj xeeb yog lub zog ntawm cov pob zeb crushed, tus nqi siab tshaj plaws yog M1400. Qhov kev ntsuas no hais txog pob zeb me me rau cov ntaub ntawv muaj zog. Nws yog tsis yooj yim sua kom tsis txhob tawm ib qho kev tiv thaiv Frost uas npaj txhij-ua xuab zeb-gravel mixs muaj. Tag nrho lawv cov npe tuaj yeem yuav hauv khw muag khoom siv. PSC feem ntau yog sau npe F300. Cov ntsiab lus ntawm plua plav thiab av nplaum tuaj yeem ncav cuag 20%, qhov ntsuas no yuav tsum raug coj mus rau hauv tus account thaum yuav khoom.
Zaj lus
Sand-gravel sib tov muaj ntau yam zoo, feem ntau ntawm lawv tau teev nyob rau hauv tsab xov xwm. Yog tias koj txiav txim siab siv cov lus piav qhia rau kev tsim kho, koj yuav tsum xub paub koj tus kheej nrog cov nqi. Tus nqi nruab nrab ntawm lub hauv paus ntawm cov khoom siv hauv tsev niaj hnub no yog txog 400rubles ib cubic meter, uas tuaj yeem hu ua tus nqi pheej yig uas yav tom ntej tus tswv ntawm lub tsev ntiag tug tuaj yeem them taus. Thiab qhov no yog lwm qhov zoo ntawm cov khoom piav qhia.
