Rubble pob zeb yog ib qho ntawm cov khoom siv hauv tsev qub tshaj plaws. Ib daim ntawv tuaj yeem hnyav txog li 40 kg thiab txog li 50 cm hauv qhov loj. Lub hauv paus ntawm extraction ntawm cov khoom no yog thaj chaw ntawm limestones, sandstones, dolomites, plhaub pob zeb, lwm yam igneous thiab metamorphic pob zeb. Tsis tshua muaj nws yog mined los ntawm granite.
Peb hom buta
Muaj peb hom pob zeb. Torn - nws yog tau los ntawm blasting. Bedous - nws tawg tawm ntawm cov pob zeb txheej. Plitnyakovy - nws yog mined los ntawm metamorphic thiab sedimentary pob zeb uas muaj shale qauv. Plitnyakovy rubble pob zeb muaj daim ntawv ntawm lub phaj, txawm li cas los xij, tsis sib xws. Tib yam tuaj yeem hais txog cov pob zeb txaj txaj txaj. Cov phiaj no, txawm tias lawv qhov tsis sib xws, muaj qhov zoo ib yam li lub ntsej muag torn. Tab sis lawv yooj yim dua los siv thaum lub sij hawm tsim kho, vim lawv yuav luag tsis tas yuav tsum tau them nqi ntxiv rau masonry. Whereas, ntxiv rau torn butu, lwm yam ntaub ntawv yuav tsum tau. Txhawm rau sau cov voids tsim thaum lub sij hawm masonry, pebbles me me thiab mortar yog xav tau. Txawm tias qhov tseeb tiasrubble pob zeb yog mined los ntawm blasting, tej yam yuav tsum tau siv rau nws. Cov qauv yuav tsum yog homogeneous, tsis muaj av nplaum thiab xoob pob zeb, tsis tawg lossis delaminated.
Key Features
pob zeb ruaj khov. Nws lub zog nyob ntawm qhov chaw nws tau mined: los ntawm lub teeb pob zeb, hnyav sedimentary los yog igneous. Nyob ntawm qhov no, lub zog yog ntsuas hauv thaj tsam ntawm 2 txog 30 MPa. Lwm qhov zoo heev ntawm cov pob zeb no yog Frost tsis kam. Nws yuav tsum yog tsawg kawg yog 15 cycles. Qhov no txhais tau hais tias cov pob zeb rubble tau khov thiab thawed tsawg kawg yog 15 zaug thiab tsis tawg thiab delaminate, tsis poob ntau tshaj 5% ntawm qhov hnyav, thiab nws tuaj yeem siv rau hauv kev tsim kho. Thaum ntaus nrog rauj, lub pob zeb yuav tsum ua lub suab nrov. Qhov no hais txog nws qhov zoo. Hloov pauv, lub suab dull txhais tau hais tias muaj ntau ntawm impurities ntawm av nplaum thiab lwm yam pob zeb. Xws li lub raj mis yooj yim tawg nrog ib lub tshuab rauj (qhov hnyav 1 kg), thiab nws yuav tawg mus rau hauv pob zeb. Yog li ntawd, cov khoom siv tsis zoo yog ua tiav rau hauv pob zeb crushed. Rau pob zeb pob zeb masonry, rubble pob zeb yog siv, tus nqi ntawm uas yog ho qis dua tus nqi ntawm tib cov khoom npaj rau cladding.
Kev tsim kho
Lub pob zeb zoo tsim nyog rau kev tso lub hauv paus ntawm cov tsev monumental, hydraulic thiab lwm qhov chaw engineering. Rubble masonry kuj yog siv rau kev tsim kho ntawm cov sumps, tso tsheb hlau luam, cov kav dej thiab cov tsev uas tsis yogyuav cua sov. Hauv qhov no, qhov hnyav ntawm pob zeb yuav tsum tsis pub tshaj 30 kg. Cov pob zeb loj heev tau muab faib ua ntej nrog lub sledgehammer rau hauv daim ntawm qhov loj me. Ib lub laj kab me tuaj yeem muab tso nrog lub pob zeb qhuav qhuav. Tsis muaj kev sib txuas lus siv ntawm no. Rau kev tsim kho siab dua, yuav tsum muaj kev sib koom ua ke. Qhov no yog ib qho ntawm cov khoom tsim nyog tshaj plaws hauv tsev. Nws tus nqi txawv ntawm 1,500 txog 20,000 rubles ib tuj. Cov ntaub ntawv raug muab tso rau txhua pawg, uas qhia txog qhov qub yug, qhov loj ntawm daim, Frost tsis kam thiab qib zog.
