Chainsaw tshuab chaw txua txiag zeb txiav kev lag luam

Sawing thiab mining ntawm pob zeb cov ntaub ntawv hais txog txoj kev txiav cov pob zeb mus rau hauv ib qho kev zoo thiab lumpiness los ntawm ntau ntau lub pob zeb masonry ntawm ntau qhov ntau, mechanical saw, wedge thiab blasting, thiab lwm yam, yuav tsum tau siv raws li raw cov ntaub ntawv rau masonry thiab tag cov ntaub ntawv ntawm civil thiab kev tsim vaj tse ubno thiab cais lawv ntawm pob zeb pob zeb.

Los ntawm kev sib txuas ntawm cov neeg kho tshuab, ntim thiab blasting, lub pob zeb txiav mus rau hauv ib qho chaw thiab lumpiness, thiab sib cais los ntawm pob zeb mass. Lub pob zeb yog siv ua raw cov ntaub ntawv rau masonry thiab tag nrho cov ntaub ntawv rau civil thiab kev tsim kho tej yaam num. Pob zeb tau siv rau hauv kev tsim kho vaj tse thiab vaj tse rau ntau txhiab xyoo, lub pyramid Iyiv, lub hauv paus ntawm lub Forbidden City nyob rau hauv Beijing, Tuam Tshoj, lub pob zeb cov kauj ruam thiab railings, pob zeb archways ntawm Ming tombs, thiab lwm yam, yog tag nrho carved nrog pob zeb masonry ntawm ntau ntau thiab tsawg. Tab sis daim ntawv ua tiav cov khoom lag luam zeb, muaj keeb kwm ntawm 100 xyoo nkaus xwb. Cov khoom siv niaj hnub no (xws li cement, thiab lwm yam), ntau dua, hloov lub pob zeb, tab sis qee lub tsev nyob ruaj khov, tseem ceeb pej xeem thiab kev ua si hauv tsev, tseem yuav tsum tau siv ntau yam khoom siv pob zeb rau kev dai kom zoo thiab phab ntsa khoom. Yog hais tias suav yun hua, dawb marble, dandong ntsuab, dai tshauv, Italian xi na yog marble gold, African xiav granite yog tos, nws yog tus zoo muag khoom ntawm kev lag luam thoob ntiaj teb, nws thov hlob tsis tu ncua.

Cov kauj ruam ntawm kawb pob tsuas yog nyob ntawm seb yam khoom nqa. Thaum siv cov crane mobile, nws yog 5 ~ 10m, thaum siv thaum siv ntauwd crane, nws muaj peev xwm ncav tau tshaj 10m. Cov khoom loj yuav txuag tau nyiaj npaum li cas rau kev npaj, kom qhov theem siab tau muaj qhov kev xav nce. Lub kauj ruam qhov siab ntawm qhov kev txiav yog tsuas yog txiav txim los ntawm qhov qhia meej ntawm sab thiab nws cov twj drilling, feem ntau 2 ~ 3m. Lub disadvantage ntawm xaim hlua pom yog tias txiav siab tsis loj. Tsis ntev tas los no, lub peev txheej tsim ntawm cov hlua xaim vibrating saw tau tuaj yeem khees me ntsis ntxiv los ntawm 32 ~ 40% dua li ntawm kev sib kis ceev. Ltalis, Soviet Union tau pib siv cov hlua pob zeb diamond hlau.

Nplaim taws kub nplhaib txoj kev siv nrog cov nplaim pob zeb, ua kom txiav ntog kom phom lub pob zeb thiab tsuas yog siv los nres uas muaj ntau cov pob zeb hauv av pob zeb, tsuas yog ntsug txiav, txiav zeeg ploj loj dua, yog tias muaj peb qho dawb, feem ntau feem ntau txiav ob tog, zoo tshaj plaws txiav tsuas yog ib sab, rau lwm ob qhov chaw nrog blasting los yog clink sib cais hom. Cov ntsej muag txiav ntawm lub nplaim taws yuav tsum tau xaiv rau ntawm feem ntau nyuaj seem thiab ntxhib hniav. Kev nrov nrov nyob rau hauv cov txheej txheem ntau lawm yog siab li 120dB, uas tsim kev puas tsuaj rau ib puag ncig thiab cov neeg ua haujlwm.
