Amarig Anama-Fixed Leader Masts

Izisebenzi ezineziqongo ezinamamast ukuze ziqondise zibonisa isigaba esikhethekile sezinsiza zokuhweba ezixhunywe ku- excavator eziklanyelwe ukwakhiwa kwemigqa nezicelo zokuthuthukiswa komhlaba. Lezi zinhlelo zisebenzisa ubuchwepheshe bokuvusa ukuze zifake izikhala, izikhala zephepha, nezinye izinto ezijulile zokwakha, ngokuhlanganisa imvamisa yokuphendula namandla adlalayo, okwenza zibe nesikhathi esihle sokuhamba izakhiwo zokwakha ezinhlobonhlobo zezilwanyana zomhlaba. Izixhobo ezinamamast angashintshi zigcina uhlaka oluqinile, oluhlelwe ngokuqondile olukhombisa inqubo yokufaka izikhala, kuqinisekisa ukunemba nokwakhiwa kwezakhiwo ngalesi sikhathi sokushaya. Ukwakhiwa komast okuqinile kunikeza izinzuzo ezihlukile emsebenzini wokushaya izikhala. Ngokungafani namamast anokuphenduka, izakhiwo eziqinile zinikeza ukuzinza okuthuthukisiwe nokusabalalisa indawo, kuvumela abaphathi ukuthi bafeze izinga lokuphumeza elivamile phakathi kokufaka okwehlukene. Lezi zixhobo ngokuvamile zibanjwa nezinsimbi zokuvusa—izinsiza zehydraulic ezikhethekile ezikhiqiza amandla aphezulu ahamba ngokuqhubekayo athunyelwa ngqo emqondweni wesikhala. Indlela yokuvusa yehlisa ukuphikisana ngesikhathi sokufaka izikhala ngokuthambisa noma ukuthonya izinsalela zomhlabathi ezisondelene, kudala ukwehla okwesikhashana ekuthinteni ubumphetho bokuphaka kobuvimba. Le ndlela ikhethekile kakhulu uma kushaywa izikhala eziphakathi kwezizinda zeqhwa ezinzima, izinqolobane zamafutha, nezinye izinto eziphalapheleyo lapho ukuziphatha okujwayelekile kungase kube isikhathi eside futhi kungenzeka kubangele umonakalo ezinsizeni ezinqeni noma ezakhiweni ezisondelene. Izisebenzi eziphakanyisiwe zokuhweba ezinokuzikhumbuza zisetshenziswa ezinhlobonhlobo zamaphrojekthi wokwakha, kusukela ezisekelweni zezimoto nasemabhulidini kuya ekuthuthukisweni kwezakhiwo zezimboni nasezinhlelweni zokuvikela kwezokuhlala. Lezi zinsiza zibaluleke kakhulu ekufakeni izikhala zensimbi, izikhala ze-H, nezikhala ezibiyelwe ezindaweni ezinezidingo ezihleliwe zokuphendula, njengezindawo zokwakha ezisemadolobheni eduze kwezinto ezikhona. Ukuhlanganiswa kwamandla okuvusa nokuhola okulungile kuvumela ukulawula ngobukhulu obuhle bokujula nokwehliswa kwesithontelo sesithombe sokuqhubekela phambili uma kuqhathaniswa nezindlela zokuphikisana, okwenza lezi zinhlelo zibe kuhle kakhulu kumaphrojekthi aneziqondiso eziqinile zendawo noma izakhiwo. Amamamast aqinile akwazi ukuhambisana nezinhlobo ezahlukene zezikhala nezilinganiso, avumela abakhiqizi nabachwepheshe bezisekelo ukuba bahlukane nezinsiza zabo ukuze zihambisane nezidingo zaphrojekthi ezithile. Izimo zomhlaba zenza ukuba umthelela omkhulu ekukhetheni nasekuphakamiseni izisebenzi ezinamamast aqinile. Lezi zinhlelo zenziwa kahle ezimweni zomhlaba eziphalapheleyo—ukudla, umsandawane, nezindawo zeqhwa—lapho imvamisa yokuvusa phakathi kuka-10 no-30 Hz yehlisa ngempumelelo ukucindezela okuhle kanye nokuphikisana komhlaba. Emazingeni aphathelene nezakhiwo zebhuku eziqinile, izisebenzi ezinamamast aqinile zingadinga izindlela zokushaya ezengeziwe noma ukuhlola umhlabathi ukuze kuqinisekiswe ukufaka okuhlengelele. Lezi zinsiza zithola impumelelo ekwakhiweni kwamabhulidi, ukuthuthukiswa kwamachweba, izinsiza zezimali eziphindaphindayo, kanye nezinhlelo zezimboni lapho izikhathi zokufaka ezisheshayo nokuhlonipha ukuma kubalulekile. Abaphathi abanolwazi nabakhokheli bezisekelo bakhetha izinhlelo zamamamast aqinile ngokusekelwe ekuhlolweni kwemibala yomhlabathi, ezichasayo zezikhala, izidingo zesikhathi sokwenza, kanye nemikhawulo yokufinyelela, kuqinisekiswe ukusebenza kahle nokufaneleka kwezindleko ngesikhathi sokufaka izisekelo ezijulile.
