Raws li suav yuav ua li cas muaj ntau yam tons ntawm cubed rubble

Mus nqa tawm ntau yam kev tsim kho tej hauj lwm, txawm tias ib tug me me scale, koj yuav tsum xub xam tus nqi ntawm cov ntaub ntawv uas yuav tsum tau. Xam daim ntaub ntawv tsis tau yooj yim. Ib me ntsis nyuaj mus nrhiav rau qhov tsim nyog tus nqi ntawm gravel, xuab zeb, av nplaum, xis mas. Lub xam ntawm tej ntaub ntawv yuav tsum tau nqa tawm kev noj mus rau hauv tus account lawv cov nta. Yog li ntawd, yuav ua li cas muaj ntau yam tons ntawm rubble nyob rau hauv ib lub voos xwmfab? Puas thaum xub thawj siab ib muag, kev txawj ntse yuav pab tau rau cov neeg uas pib nws tus kheej siv. Thiab txawm hais tias koj npaj yuav siv tus neeg ua haujlwm, tseem tswj cov ndlwg ntawm cov xuab zeb thiab gravel muaj, vim hais tias mus them rau nws yuav yeej koj.

Yam influencing kev txiav txim ntawm lub loj ntawm rubble

Yuav kom xam ntau npaum li cas tons ntawm rubble nyob rau hauv ib lub voos xwmfab, koj yuav tsum xav txog cov nram no:

• Hom ntawm cov pob zeb los ntawm qhov uas cov ntaub ntawv uas yog ua;
• loj feem;
• flakiness;
• vlagopogloschaemost.

Tej yam zoo peb xav txog nyob rau hauv tsab xov xwm.

hom gravel

Koj twb zaum pom tias, chippings yuav txawv. Nyob rau hauv geology delve tsis nqi nws, vim hais tias ntawm tag nrho cov pob zeb ua tau kom gravel, dua nws los ntawm lub li. Txhua yam tsiaj nws muaj nws tus kheej ceev, uas, nyob rau hauv lem, muaj feem xyuam rau cov kev nqus. Muaj ob peb hom rubble:

• granite;
• basalt;
• gravel;
• limestone.

Ib tug cov ntaub ntawv uas yog thawj nyob rau hauv daim ntawv, yog muab rho tawm los ntawm quarries nyob rau hauv lub pob zeb granite pob zeb. Nws yog tsim los ntawm kev sib tsoo cov khib nyiab tau tom qab blasting. Crushed granite muaj durability thiab tej yam ntuj tso xim. Nws yog feem ntau thiab yog siv rau cov kev siv ntawm ntau yam lug, cov me nyuam yaus, txoj kev. Tsis tas li ntawd, cov khoom ntawm granite yog siv rau cov hniav hom phiaj.

Basalt gravel mined los ntawm pob zeb basalt. Raws li nws tus yam ntxwv, qhov no cov ntaub ntawv uas yog ib tug competitor rau granite pob zeb. Basaltic gravel muaj siab thermal conductivity, ceev, lub zog, te kuj. Nws yog siv raws li tub lim nyob rau hauv lub chaw ua khoom ntawm heavy ua vaj tse, nyob rau hauv kev tsim kho ntawm txoj kev chaw, rau tag vaj tse.

Gravel chippings ua los ntawm xoob sedimentary pob zeb. Qhov no cov ntaub ntawv uas muaj tus duab ntawm sib npaug pebbles. Nws yog siv nyob rau hauv txoj kev siv. Me fractions yog siv raws li ib tug hniav khoom. Gravel muaj ib tug txaus siab zoo kev ua tau zoo thiab tsis muaj nqi.

Limestone rubble yog ib tug tshwj xeeb tsev ntaub, uas yog muab rho los ntawm limestone - ib tug sedimentary pob zeb. Nws yog ib co resistant rau thermal poob siab thiab tej yam kuj. Qhov no yog ib qho environmentally phooj ywg cov ntaub ntawv uas. Nws siv limestone gravel nyob rau hauv txoj kev siv, zus tau tej cov txiv qaub. Nws kuj yog siv raws li ib tug hniav pob zeb.

chipping loj

Tag nrho cov hom ntawm gravel raug muab faib mus rau hauv cov zauv feem, txhais tau nws loj. Xav txog tej yam ib lub voos xwmfab nrog ntug ntev ntawm 10 hli los yog pob nrog lub tib txoj kab uas hla. Thiab tam sim no - ib tug ua pob thiab tsuav ib tug me ntsis ntau, piv txwv li, 20 mm. Siv ib Rev ntawm sawv daws yuav thiab lwm tus, thiab ces sib tov. Nyob rau hauv lub kawg, koj tau txais qhov luaj li cas (feem) 10-20.

Qhov tseem nrhiav-tom qab los ntawm cov kev pab yog crushed granite 5-20. Qhov no cov ntaub ntawv uas yog siv rau qhov siv thiab ua manually sidewalks, pavement vuas, tsheb chaw ua si, raws li zoo raws li nyob rau hauv qhuav ntawm ntau yam qhob khoom. Nyob rau hauv kev twb kev txuas nrog rau qhov no lub caij ntuj sov neeg nyob thiab tus tswv tsev ntawm ib tug neeg lub tsev yog xav nyob rau hauv yuav ua li cas muaj ntau yam tons ntawm crushed pob zeb lub voos xwmfab fractions 5-20. Peb yuav tsis thauj koj cov lus teb thiab nthuav qhov nruab nrab volume ceeb thawj. Rau ib feem ntawm gravel nws yog 1,38 t / m ^3.

Nyob rau hauv thawj zaug rau theem ntawm kev tsim kho ntawm ntau yam khoom siv ib tug loj pob zeb. Nws yuav tsum tau crushed granite 20-40. Nws tau thov rau sau lub entrances rau lub tsev qhov chaw cov me nyuam yaus. Nyob rau hauv kev txiav txim siab kom lub tsev project ntawm no cov ntaub ntawv uas, peb yuav tsum paub ntau npaum li cas tons ntawm crushed pob zeb lub voos xwmfab fractions 20-40. Lub volumetric hnyav ntawm lub pob zeb - 1,41 t / m ^3.

Rau txoj kev filling thiab cov cheeb tsam uas yuav tsum tau loj load yog thov gravel loj 40-70. Heev feem ntau nws yog siv rau kev kho nyob rau hauv lub tsev chaw flowable av. Yuav ua li cas muaj ntau yam tons ntawm crushed pob zeb lub voos xwmfab nyob rau hauv feem 40-70 - yooj yim mus nrhiav. Tab sis tsis txhob nkim lub sij hawm rau suav. Crushed granite muaj ib tug nruab nrab volumetric luj ntawm 1,47 t / m ^3.

Nyob rau hauv lub railway, industrial, thaj tsim kho, nyob rau hauv qhov siv thiab ua loj heev ua kev reinforced lug siv gravel loj 25-60. Ordinary cov neeg siv, uas siv cov khoom siv no rau txawv vaj tse, lawv xav paub yuav ua li cas muaj ntau yam tons ntawm cubed rubble fractions 25-60. Teb: nyob rau hauv ib tug cubic Meter ntawm 1,38 m pob zeb ntawm ib tug muab me me.

flakiness

Flakiness (daim ntawv no) - ib qho ntawm qhov tseem ceeb tsis tau xav txog thaum txiav txim yuav ua li cas muaj ntau yam tons ntawm cubed rubble. Los ntawm tej yam daim ntawv no yog cov ntaub ntawv uas - ib tug phaj-li, rab koob zoo li los yog cuboid, cov kev ceev ntawm lub sau theem ntawm volume nyob. Nyob rau hauv kev txiav txim kom tsis txhob tuaj nyob puv nkaus ntawm qhov yooj yim cov ntaub ntawv thiab rau ntau tuab filling yuav tsum yuav rubble flakiness tsis ntau tshaj li 15%.

dej saturation

Dej saturation - ib kauj uas muaj feem xyuam rau qhov loj ntawm rubble. Qhov ntau khib nyiab, ntau dua qhov lub daim duab. Qhov nruab nrab feem pua, nyob ntawm seb lub hom gravel, los mus rau 10%. Dej saturation littered cov ntaub ntawv uas nce mus txog 100% los yog ntau tshaj. Tsis xav yuav gravel uas zoo xws li khib nyiab: qias neeg los yog nrog ib tug ntau ntawm cov xuab zeb. Dhau li ntawm tus fact tias nws yog hnyav zog, tej khoom yuav tau ua los ntawm kev tsim pov tseg. Nws cov nqi pheej yig dua.

Kev ntiajteb txawj nqus (SG)

Tag nrho cov saum toj no yam li ib tug tag nrho thiab ib lub zuj zus, kev cuam tshuam rau qhov kev txiav txim ntawm yuav ua li cas muaj ntau yam tons ntawm cubed rubble. Cov nuj nqis txawv me ntsis nyob rau hauv sib txawv thaj thiab cov huab cua puag. Yog hais tias koj xav mus nws tus kheej xam tej kev ceev ntawm crushed pob zeb, ntsuas muab los ntawm ib yam ntawm 1.4, thiab tau txais ib tuj. Txhais conversely, yooj yim heev. Yog hais tias koj muaj cov nyiaj nyob rau hauv tons, faib nws los ntawm 1.4 - thiab tau txais ib tug tshwm sim ntawm nyhav peev xwm.
