Ib yam yuav hais txog postelistom rubble. Cov phiaj no, txawm nws muaj kev roughness, muaj tib zoo raws li lub ragged saib. Tab sis lawv muaj ntau nyiam siv nyob rau hauv kev tsim kho, txij li thaum lawv yuav tsum tau yuav luag tsis muaj nqi ntxiv rau tso. Whereas lwm yam ntaub ntawv uas yuav tsum tau nyob rau hauv tas li ntawd mus rau lub ragged rooj muag zaub. Yuav kom sau cov voids tsim nyob rau hauv lub masonry, yuav tsum me me pob zeb thiab mortar. Txawm tias muaj tseeb hais tias cov rubble pob zeb yog mined los ntawm blasting, yuav thov tej yam uas yuav tsum tau. Tus qauv yuav tsum niaj hnub zoo li, tsis muaj impurities av nplaum thiab xoob pob zeb, tsis muaj tej kab nrib pleb thiab tej yam tshwm sim ntawm kev sib cais.

Ntsiab nta

Heev muaj zog pob zeb. Nws lub zog yog nyob rau ntawm, qhov uas nws tau muab rho tawm: los ntawm lub teeb pob zeb, hnyav igneous los yog sedimentary. Nyob rau hauv no lub dag lub zog yog ntsuas nyob rau hauv lub chav los ntawm 2 mus rau 30 MPa. Lwm ntawm lub zoo heev thaj chaw ntawm cov pob zeb no - te. Nws yuav tsum muaj tsawg kawg yog 15 mus. Qhov no txhais tau tias lub rubble pob zeb raug khov thiab yaj tsawg kawg yog 15 lub sij hawm thiab tseem tsis crumble thiab flake, tsis poob ntau tshaj 5%, thiab nws yuav siv tau nyob rau hauv kev tsim kho. Thaum ntaus nrog ib tug rauj zeb yuav muab ib tug ringing suab. Nws hais txog nws cov high quality. Conversely, clunk txhais tau tias ib tug loj npaum li cas ntawm impurities thiab lwm hom ntawm cov av nplaum. Tej fwj yooj yim tawg ib tug rauj (yuag: 1 kg), thiab nws yuav crumble mus rau hauv rubble. Yog li ntawd substandard khoom ua mus rau hauv gravel.

Siv nyob rau hauv kev tsim kho

Pob zeb yog zoo suited rau tso cov me nyuam yaus ntawm monumental tsev, hydraulic thiab lwm yam engineering chaw. Masonry chaw txua txiag zeb pob zeb no kuj siv rau qhov kev siv ntawm lub taub dej khawb tso tsheb hlau luam, tso tsheb hlau luam, dej thiab cov vaj tse uas tsis yog rhuab. Yog li pob zeb hnyav yuav tsum tsis ntau tshaj 30 kg. Heev pob zeb loj loj nrog ib tug sledgehammer rau ib tug pre-cais daim haum loj. Me laj kab yuav pw Bout los ntawm qhuav tso. Muaj tsis siv rau tsevneeg tshuaj. Rau ntau ntau vaj tse yuav tsum tau cov phau ntawv tshuaj. Qhov no yog ib qho ntawm feem tsim nyog cov ntaub ntawv. Nws nqi yog hom twg los ntawm 1,500 mus 20,000 rubles ib ton. Rau txhua batch ntawm muab cov ntaub ntawv uas qhia cov niam txiv yug menyuam, luaj li cas ntawm daim, lub hom zog thiab te kuj.
