Namuhla emnothweni wemakethe, ngokuthuthuka okuqhubekayo kobuchwepheshe, kanye nentuthuko eqhubekayo yesayensi nobuchwepheshe, inkambu yamanje yobunjiniyela emnothweni wemakethe inomkhuba othile wokuthuthuka, futhi manje iphini lebhakede lisetshenziswa kakhulu ku-excavator yanamuhla ngaphezulu. kabanzi.Ekusetshenzisweni kwemishini yayo, inezici ezinhle.Ukuze yenze imikhiqizo yayo isetshenziswe, ibe nomsebenzi omuhle, ngakho ekukhiqizeni okuhambisanayo nasekukhiqizeni, kunezindinganiso ezithile.
Emgqeni wezinyo lebhakede ukuze kusetshenziswe okuhambisanayo kunomsebenzi omuhle, manje abantu ekucubunguleni okuhambisanayo kwemikhiqizo yayo, kunezindinganiso ezithile.Okusho ukuthi, lapho umkhiqizo ophelile ukhiqizwa, ukugeleza kwenqubo evamile kuyamukelwa. Enqubweni yokucubungula ehambisanayo, kukhona ukubunjwa kwesihlabathi, ukubunjwa nokunemba.Enqubweni yokuphonsa ehambisanayo, kunamazinga ahlukene.
Iphinikhodi yebhakede ekusetshenzisweni kwabantu, ngenxa yomsebenzi wayo omuhle, ngakho-ke ingasetshenziswa kabanzi ekusetshenzisweni kwemishini ehlukene.Ukuze ulenze isicelo, linesici esihle, ngakho-ke liqhuba ukukhiqizwa okuhambisanayo nomkhiqizo walo, lizokwenza. qhubeka nokukhiqiza ngokwesicelo esiqinile.
1. Inqubo yokubumba ihlanganisa: ukusika izinto zibe izilinganiso ezidingekayo, ukufudumeza, ukubumba, ukwelashwa kokushisa, ukuhlanza nokuhlola.Ephepheni elincane lezandla, yonke le misebenzi yenziwa inqwaba yabakhandi bensimbi, isandla nesandla, endaweni encane. .Bonke bachayeka ezingozini ezifanayo eziyingozi zendawo ezungezile kanye nomsebenzi;Ezingqungqutheleni ezinkulu zokuqopha izinto, izingozi ziyahlukahluka ngomsebenzi.
Izimo zokusebenza nakuba izimo zokusebenza zihluka ngokuya ngohlobo lokukhanga, zinezici ezithile ezifanayo: umsebenzi wezandla oqinile, i-microclimate eyomile neshisayo, umsindo nokudlidliza, kanye nokungcoliswa komoya ngenxa yentuthu.
2. Izisebenzi zichayeka ekushiseni okuphezulu komoya kanye nemisebe eshisayo ngesikhathi esisodwa, okuholela ekunqwabelaneni kokushisa emzimbeni, ukushisa kanye nokushisa kwe-metabolic, okuholela ekungalinganini kokushisa nokuguquka kwe-pathological. Inani lokujuluka elikhiqizwa i-8- ukusebenza kwehora kuzohluka ngendawo encane yegesi, ukuzikhandla ngokomzimba, nezinga lokujwayela okushisayo, ngokuvamile ukusuka ku-1.5 kuya ku-5 amalitha, noma ngisho nangaphezulu.Eshabhubhu encane yokubumba noma kude nomthombo wokushisa, inkomba yokucindezeleka kokushisa ye-BJH. ngokuvamile i-55 ~ 95.Kodwa-ke, endaweni yokusebenzela enkulu yokubumba, indawo yokusebenza eduze kwesithando somlilo noma umshini wesando wokuwisa ingase ibe phezulu njenge-150 ~ 190.Kubangela kalula ukuntuleka kosawoti kanye nokushisa kwe-spasm.Ukuchayeka ekushintsheni kwe-microclimatic ngesikhathi kubanda. inkathi ingase ibe nomthelela ekuzivumelaniseni nezimo, kodwa izinguquko ezisheshayo nezivamile zingase zibe yingozi empilweni.
Ukungcoliswa komoya: umoya osendaweni yokusebenza ungase ube nensimu, i-carbon monoxide, i-carbon dioxide, i-sulphur dioxide, noma i-acrolein, kuye ngohlobo lukaphethiloli osetshenziswa esithandweni sokushisa nokungcola okuqukethwe, kanye nokusebenza kahle komlilo, ukugeleza komoya, kanye nokukhipha umoya. .
Umsindo nokudlidliza: uhlobo lokukhanga isando nakanjani luzokhiqiza umsindo ophansi kanye nokudlidliza, kodwa futhi lungase lube nezingxenye ezithile zefrikhwensi ephezulu, izinga lokucindezela komsindo elingu-95~115 db.Ukuchayeka kwabasebenzi ekudlidlizeni kokubumba kungase kubangele izinga lokushisa kanye nokungasebenzi kahle, okungase kwehlise ikhono lokusebenza futhi kuthinte ukuphepha.
