Umthengisi wezixhobo zokwakha izisombululo zoomatshini bokwakha kangangeminyaka engama-30.
Lo matshini unepleyiti yentsimbi esisicaba ezantsi. Injini encinci yepetroli okanye yedizili ijikelezisa ubunzima obungaphandle kombindi ngaphakathi, nto leyo edala ukungcangcazela okunamandla okunyuka nokuhla. Oku kungcangcazela, kunye nobunzima bomatshini, kutyhala amasuntswana omhlaba kufutshane kwaye kususe izithuba zomoya. Uninzi lweemodeli lungcangcazela phakathi kwamaxesha angama-4000 nama-5800 ngomzuzu, kwaye amandla eziwavelisayo alinganiswa ngee-kilonewtons (kN). Amandla aphezulu athetha ukuxinana okunzulu kwiphasi enye.
Ubukhulu beepleyiti ezahlukeneyo butshintsha indlela umatshini oziphatha ngayo. Iipleyiti ezimxinwa (ezimalunga ne-35–50 cm ububanzi) zifikelela kwiikona ezixineneyo kakuhle, ngelixa iipleyiti ezibanzi (ukuya kuthi ga kwi-67 cm) zigubungela umhlaba omninzi ngokukhawuleza. Izixhobo zerabha ezifunxa ukothuka zigcina uninzi lokushukuma kude nezandla zomqhubi ukuze umsebenzi ungabi nzima.
Abakhi basebenzisa ii-vibratory plate compactors kwimisebenzi emininzi yemihla ngemihla. Balungiselela iziseko phantsi kweendlela zegadi, iindlela zokungena, iipatio kunye nokulungiswa kweendlela ezincinci. Isanti kunye negrabile zisabela kakuhle kuba ukungcangcazela kunceda iinkozo zihlangane kakuhle. Umxube wekhonkrithi owomileyo kunye namatye amancinci nawo uqina kakuhle kwiziseko kunye neeslabs.
Kwimisebenzi ye-asphalt imeko iyatshintsha. I-asphalt eshushu okanye ebandayo inamathela kwipleyiti eyomileyo kwaye yenza iindawo ezingalinganiyo. Yiyo loo nto iimodeli ezinetanki yamanzi eyakhelwe ngaphakathi zitshiza ulwelo oluncinci lwamanzi ukuze ziyeke ukunamathela kwaye zinciphise uthuli ngaxeshanye.
Iimodeli ezibhekisa kwicala elinye zihamba phambili kuphela. Zikhaphukhaphu (ngesiqhelo ziyi-65–120 kg) kwaye kulula ukuziphatha ngee-handles ezigoqekayo okanye amavili amancinci. Ezi zilungele iindawo ezivulekileyo ezithe tyaba ezifana neendlela zokungena okanye uyilo lwegadi apho unokuhamba khona ngemigca ethe tye.
Ii-reversible plate compactors zihamba phambili nangasemva, kwaye ezininzi zinokungcangcazela kwindawo enye. Oku kusindisa ixesha elininzi kwimisele emincinci, ecaleni kweendonga, ezijikeleze iziseko okanye kwiindawo ezixineneyo apho ukujika umatshini ngesandla kunzima khona. Iiyunithi ezinzima eziguqukayo (125–330 kg) zinika amandla aqinileyo (25–38 kN) kwaye zifikelela kubunzulu bokuxinana ukuya kuthi ga kwi-90 cm, nto leyo ezenza zibe lolona khetho lungcono lomsebenzi onzulu okanye oxineneyo.
Soloko uqala ngobukhulu obuchanekileyo bezinto. Yandlala umhlaba okanye igrabile kwiileya ezingatyebanga ngaphezu kokuba umatshini unako ukuyiphatha (ngesiqhelo yi-20-40 cm kuxhomekeke kumandla). Yenza iipaseji ezintathu okanye ezine ezijikelezileyo phezu kweleya nganye ngelixa uhamba ngesantya esizinzileyo.
Jonga ubumanzi bomhlaba kuqala. Igrabile emanzi kakhulu ingenza ipleyiti itsibe kwaye ingahambi kakuhle. Kwi-asphalt, vula ivalvu yetanki yamanzi uze ugcine itanki igcwele. Ngaphandle kwamanzi ipleyiti iyarhuqa kwaye ishiye amabala arhabaxa.
Nxiba iiglavu, izikhuseli zeendlebe kunye nezihlangu eziqinileyo ngalo lonke ixesha. Emva kokugqiba, susa udaka kunye namatye kwipleyiti nakwifreyimu ukuze kungabikho nto iqina ize ibangele ingxaki kwixesha elizayo.
Eyona nzuzo inkulu kukuphucula umhlaba ngokukhawuleza nangokuthembekileyo okuthintela ukuhlaliswa kwakhona kwixesha elizayo. Iimodeli eziguqukayo zigqiba imisebenzi ngokukhawuleza kwiindawo ezinzima kwaye zinciphisa umgudu womqhubi. Iipleyiti ezibanzi kunye namandla aphezulu e-centrifugal anyusa imveliso yemihla ngemihla, ngamanye amaxesha ifikelela kwi-500–650 square metres ngeyure.
Ukukhetha umatshini ochanekileyo nakonga imali. Imodeli ehambelana nohlobo lomhlaba, ubunzulu obufunekayo kunye nobukhulu bendawo ithintela ukudlula okongeziweyo, inkunkuma yepetroli kunye nokulungiswa kwakhona. Iimpawu ezifana nezitshixo zokukhusela ioyile kunye neepleyiti zesiseko eziqinileyo zigcina ukulungiswa kuphantsi kwiminyaka emininzi yokusetyenziswa.
Jonga zonke iibholithi emva komsebenzi ngamnye uze uqinise naziphi na ezivakala ngathi zikhululekile. Izinto eziqinileyo zinciphisa amandla kwaye zinokwaphula iindawo ezibizayo. Tshintsha ioyile yenjini emva kweeveki ezimbini zokuqala zokusetyenziswa, uze emva koko rhoqo emva kweenyanga ezintathu ukuya kwezintlanu.
Kwiimeko ezinothuli hlamba okanye utshintshe isihluzo somoya rhoqo. Ukuba injini ayivuthi, jonga ipetroli, iplagi yespark kunye nekhaburetha kuqala - uninzi lweengxaki zivela kwezi ndawo zintathu.
I-plate compactor egcinwe kakuhle inika ukusebenza okuzinzileyo kwisanti, igrabile, umhlaba oxutyiweyo kunye ne-asphalt. Ukudibanisa amandla e-centrifugal, ububanzi beplate, uhlobo lwendlela kunye netanki yamanzi kwiimeko zakho zokusebenza zokwenyani kunika isantya esifanelekileyo, umgangatho wokugqiba kunye nexabiso lexesha elide kwiprojekthi nganye.
