SPLG: dab tsi yog nws thiab cov hau kev ntawm kev siv

Nyob rau hauv niaj hnub siv no yog siv ib tug loj npaum li cas ntawm tej yam ntuj tso tsis-metallic cov ntaub ntawv, thiab mixtures thereof. Nyob rau hauv feem ntau tus neeg mob, nws yog ib lub xuab zeb, gravel thiab av nplaum. Tom qab ntawm reservoirs, dej ntws thiab seas ua ib tug sib tov ntawm xuab zeb thiab gravel, uas yog lub hauv paus SPLG. Yuav ua li cas yog nws thiab dab tsi yog qhov txawv nruab nrab ntawm tus ASG thiab SPLG?

Ib tug sib tov ntawm tej yam ntuj tso ntaub ntawv

Xuab zeb-gravel mixtures yog heev nrov thiab yog ib feem ntawm lub pob zeb ua lug, uas yog siv nyob rau hauv kev tsim kho ntawm lub tsev, txoj kev, paving, tso lub hauv paus. Zoo mixtures thiab lawv lub zog yog nyob ntawm seb seb, qhov uas lawv raug ntes. Lub ntsiab ntsuas no yog qhov tus fastening zog. Feem ntau nws yuav tsum tau ib tug sib tov nyob rau hauv uas tus nqi ntawm cov gravel nce. Yuav kom qhov no tov yog ntxiv rau lub ntuj gravel. Siv tsim rau cov khoom no - vibrating npo. Cov no ib tug sib tov OPGS, seev suab uas - enriched xuab zeb-gravel sib tov. Artificially enriched sib tov nkag mus rau lub pob zeb ua muaj pes tsawg leeg: nws yog ua ke nrog xis mas thiab dej. Qhov loj tshaj plaws - yog tus ua kevcai nco txog proportions, yog li ntawd lub pob zeb ua yog txoj cai zoo rau lub hom phiaj rau cov uas nws yog npaj. Cov muaj nuj nqis thiab zoo tshaj ntawm gravel nyob rau hauv lub Scope ntawm lub pob zeb ua. Ntuj PLG sib tov muaj txog li 20% gravel, hos cov - tus nqi twb tau nce mus rau 75%, raws li pom nyob rau hauv cov kev yees duab. SPLG thiab hais txog artificially enriched CBC muaj pes tsawg leeg.

Muaj pes tsawg leeg thiab cov division rau hauv pab pawg OPGS

Ntawm kuj zoo kawg tseem ceeb yog grain loj thiab crushing, lub xub ntiag ntawm av nplaum thiab xuab zeb nyob rau hauv lub ntoos sib xyaw. Tag nrho cov no muaj feem xyuam rau cov ntsuas xws li lub dag lub zog SPLG. Yuav ua li cas nws yog: Zoo ntsuas ntawm qhob? Nws tsis yog tsuas yog lub dag lub zog, tab sis kuj te.

Ib qho ntawm feem nrov OPGS xam tau tias yog ib tug sib tov nyob rau hauv uas lub gravel cov ntsiab lus ntawm 70%. Qhov seem 30% feem pua - yog xuab zeb, wherein tsis muaj impurities. Tab sis nyob rau hauv lub ntoos sib xyaw tej zaum yuav tam sim no av nplaum, tsis ntau tshaj li 1% los ntawm qhov ceeb thawj, thiab mus txog rau tsib feem pua ntawm cov organic tshuaj. Lis gravel tuaj nyob rau hauv ntau ntau thiab tsawg, los ntawm 10 mus rau 70 mm. Nws yuav tsum tsis txhob yuav ib tug mix. Cov sib tov siv ib tug grain fractions: Loj ntawm lawv muaj peev xwm yuav yog 10 los yog 40, 20 los yog 70 mm. SPLG muab faib mus rau hauv pab pawg raws li lawv cov ntsiab lus ntawm cov feem pua ntawm cov gravel:

• 25%;
• los ntawm 25 mus 35%;
• los ntawm 35 mus rau 50%;
• los ntawm 50 mus rau 65%;
• mus rau 75%.

dosing

Ib yam li muab faib mus rau hauv pab pawg SPLG (nws yog dab tsi - twb decoded), thiab pob zeb ua ua los ntawm ntau hom. Nws tag nrho cov nyob rau qhov twg thiab rau dab tsi lub hom phiaj yog siv. Standard Kev npaj: sib tov noj plaub qhov chaw, ib tug - ½ ib feem xis mas thiab dej. Ib feem ntawm cov khoom xyaw yog txiav txim los ntawm ceeb thawj. Thaum qhob yog npaj txhij rau tso lub hauv paus, lub pom piv ntawm qhov chaw - 1: 8. Muab tus nqi ntawm cov gravel nyob rau hauv lub muaj pes tsawg leeg, lub hom MAAs uas yog muab rau hauv cov kev npaj ntawm ib tug sib tov npaj qhob ntawm lub cim yog yuav tsum tau. Cov kev siv ntawm OPGS ua ib co khaubncaws sab nraud povtseg nyob rau hauv lub puag los yog sab saum toj lub tsho tiv no txoj kev. Nrog rau qhov kev tsim kho kev ua vaj tse vaj tse siv tsis tau tsuas yog rau cov hauv paus, tab sis kuj rau MAAs screeds rau pob zeb ua plag tsev. Lub chaw uas zoo heev nyob ib ncig ntawm lub tsev, toj roob hauv pes tsim yog tseem ua nrog rau qhov kev pab los ntawm vaj tse thiab mixtures SPLG.

tshwj xeeb tshaj yog ib tug sib tov ntawm

Raws li ib tug lub tsev cov ntaub ntawv uas sib tov yog heev ke thiab yog heev nrov nyob rau hauv kev tsim kho ua hauj lwm. Tom qab tag nrho, nws txig raws qhov chaw. Tshwj xeeb tshaj yog pab tau yog cov zoo nyob rau hauv paving txoj kev.

Tag nrho cov yam ua rau tus nqi ntawm SPLG. Yuav ua li cas yog nws thiab yuav ua li cas koj puas paub qhov feem pua ntawm tag nrho cov inclusions? Nws yuav tsum tsis pub tshaj 3% ntawm tag nrho cov ceeb thawj. Nws yog ib nqi hmoog rau lub fact, uas feem nyob rau hauv gravel lawv yuav tsum tsis txhob ntau tshaj qhov ntev ntawm 40 mm. Tag nrho cov ntaub ntawv qhia nyob rau hauv cov ntaub ntawv lees tias ua raws cai nrog rau cov uas yuav tsum tau ntawm GOST sib tov.
