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 lokusetshenziswa 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 kokusakaza.Enqubweni yokuphonsa ehambisanayo, kunamazinga ahlukene.
Iphini lebhakede ekusetshenzisweni kwabantu, ngenxa yomsebenzi walo omuhle, ngakho-ke lingasetshenziswa kabanzi ezinhlelweni zokusebenza zemishini ehlukene.Ukuze ulenze ohlelweni, 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 oqine ngokusesilinganisweni, 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 kokukhipha ukushisa kanye nezinguquko ze-pathological. Inani lokujuluka elikhiqizwa yi-8-- ukusebenza kwehora kuzohluka ngendawo encane yegesi, ukuzikhandla ngokomzimba, kanye 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.Nokho, endaweni yokusebenzela enkulu yokukhanga, indawo yokusebenza eduze kwesithando somlilo noma umshini wesando wokuwisa ingase ibe phezulu njenge-150 ~ 190.Kubangela kalula ukuntuleka kosawoti kanye nokushisa okushisayo.Ukuvezwa izinguquko ezincane ze-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 ovamile ophansi kanye nokudlidliza, kodwa futhi kungase kube nezingxenye ezithile zefrikhwensi ephezulu, izinga lokucindezela komsindo elingu-95~115 db. okungase kwehlise ikhono lokusebenza futhi kuthinte ukuphepha.
