Ibhakede leMisebenzi

Ama-backhoe loaders iyimishini elula, eyenziwe ngamasondo noma iziqephu ezithutha umhlaba, enezinhliziyo ezimbili ezihlanganisiwe: ibhakede eliqondile elikhululekile phambili nesikhwama sokumba esikhaleni esingemuva esinobhakede obuhlangene. Ngokuqhubeka kokuqala nezinsiza zokwakha ezinzima zokwakha izisekelo ezijulile kanye nezindonga zomhlaba, ama-backhoe loaders adlalela indima ebalulekile njengemishini esiza ukuphakamisa imisebenzi eyinhloko yokwakha yamawalladi wamadibha, izicathulo zokuphuma, izinhlu zezakhiwo ze-secant kanye ne-tangent pile, izindonga ze-sheet pile, kanye nezifakeli ze-jet grouting. Le mishini ayenzi ukwakhiwa kwezakhiwo eziyinhloko, kodwa inikeza ukwesekwa okubalulekile kwe-logistics, ukubhoboza, nokuphatha impahla okuvumela ukuqhuba kahle kwemisebenzi ethile yokwakha izisekelo. Ama-backhoe loaders asetshenziswa ezifundeni eziningi zokwakha izindonga zomhlaba. Ngesikhathi sokulungiselela indawo, ahlola futhi ahlukanise amabhithi ezisekelo, alawula ukuhlela impahla ebanjiwe yenziwa kanye nomhlaba ophumile, futhi ilungisa izindlela zokufinyelela ezilayisheni ezinzima zokubhoboza kanye nezinsiza zokukhama. Ngesikhathi sokwakha esisebenzayo, aphatha ukuhamba kwemikhiqizo emikhulu kuhlanganise ukulungisa nokwabiwa kwe-bentonite slurry, ukuhamba kwezinsiza zokwenziwa kwensimbi, ukuhamba kwemikhono yokubhoboza kanye nemiphetho, nokukhipha okuqhubekayo kokukhipha emadlalweni ewumugqa wamadibha noma emigqeni yokukhama ethulwe. Isikhwama sokumba esisemuva sihlinzeka indawo ethile yokuphuma nokukhipha impahla ezindaweni ezinomkhawulo, kuyilapho umtshali ophambili uhlinzeka ngamandla okuphatha impahla amaningi, okwenza ama-backhoe loaders akhethekile kumaendawo anezithiyo zomhlaba noma izigaba ezinzima lapho ukuhamba kwemikhiqizo okunembile kubalulekile. Umqondo wokusebenza uhlanganisa amasistimu amabili e-hydraulic azimele: ama-hydraulics obhonzu anikeza ukuphakamisa nokulawula ibhakede ukuze kusebenze phambili, kuyilapho ama-hydraulics ama-backhoe asebenza ngenkanyezi, isikhumba, kanye nebhakede elingemuva ngokuzimela. Le msebenzi emibili ivumela abakhiqizi ukuba balekelele, babhobe, futhi bahlukanise impahla njalo. Ezindaweni ze-diagram, ama-backhoe loaders alawula i-clay noma i-sand slurry esekela izindonga ze-trench, agcine izimpahla ezikhashiweyo, futhi aphathe izivolumu zomhlaba ezihambile. Ukuze kufakwe izinhlinzeko ezikhama esikhathini sokusebenzisa i-jet grouting techniques, le mishini ibeka futhi ihambisa iziqu ze-grouting slurry futhi ilawule amakhemikhali e-cement. Izinhlelo ze-tangent kanye ne-secant pile zithola izinzuzo ekuqondiseni kahle ibhakede ze-backhoe loaders zokuhambela nokuphatha imikhono. Izikhala ezitholakalayo zifaka ama-loader anamasondo angu-rigid-frame anesisindo sokusebenza esivela phakathi kwezitho ezintathu kuya kwezine, okukuhle kwama-platfomu asezingeni eliphezulu, kanye nezinguquko ezihambile ezine-pressure ephansi (0.4–0.8 MPa) eyenzelwe imithofu ethambile, ethokozisa, noma ehlanzekile. Amandla wokuwela kahle ajwayele ukufika ukusuka ku-0.1 kuya ku-0.35 cubic meters, namazinga okumba aphakathi kuka-4 kuya ku-5.5 metres. Izixhumi ezikhethekile zifaka ama-grapple buckets okuhweba izinhlanga, ama-plates anomagazini okuthola insimbi, kanye nezinhlelo zokuxhuma ezisheshayo ezivumela ushintsho lokusebenza olusheshayo. Izinhlelo zokukhetha zifaka umthwalo we-sithebhu endaweni yokusebenza kanye nesikhala esitholakalayo, ivolumu impahla edingekayo kanye nezinga lokuphatha, izimo zomhlaba kanye nengxenye yesikhathi (isikhathi esinomswakama vs isikhathi esomile esidinga izinguquko ezihambile), ukuhambisana kokuhamba kwemifula endaweni nokuphathwa kwe-slurry, kanye nemikhakha ye-skills yokusebenza. Izindleko zokuhamba, ukusetshenziswa kwefutha, nezinsiza zokugcinwa endaweni ziwumgomo wezomnotho ohlobene. Izindinganiso zomhlaba wonke zekhomithi ISO 6165 (ukuhlukaniswa kwemishini yokuthutha umhlaba), ISO 11001 (izidingo zokuphepha), kanye nemiyalo yemishini yasekhaya (2006/42/EC) ilawula ukuklama nokusebenza, nakuba ama-backhoe loaders avame ukuba khona ezindinganiso ezithile eziphathelene nezisekelo (EN 14104, DIN 4123) eziphathelene nemishini yokwakha eyinhloko.
