Umthengisi wezixhobo zokwakha izisombululo zoomatshini bokwakha kangangeminyaka engama-30.
Amandla okuxinana kweplate compactor yenye yeenombolo zokuqala ezijongwa ngabathengi, kodwa ikwayenye yeenombolo ezilula kakhulu ukungaqondi. Umgangatho ophezulu we-kN ubonakala unamandla kwiphepha leenkcukacha, kodwa ukusebenza kwendawo yomsebenzi kuxhomekeke kwinto engaphezulu kwamandla kuphela. Ukuphindaphinda, ubungakanani beplate, ubunzima bomatshini, uhlobo lomhlaba, ubukhulu bomaleko kunye nokufuma konke oku kugqiba ukuba iplate compactor isebenza kakuhle kangakanani.
Cinga ngokukhetha izihlangu kwindawo yokwakha. Izihlangu ezinkulu zinokubonakala ziqinile, kodwa ukuba azilingani nomhlaba, awuyi kuhamba umgama omde. Ingqiqo efanayo iyasebenza kwi-plate compactor. Umatshini ofanelekileyo awusoloko unenani elikhulu. Nguwo othumela amandla okungcangcazela afanelekileyo kwizinto ezifanelekileyo kubunzulu obufanelekileyo.
Amandla okuxinana ngamandla okungcangcazela adluliselwa yi-plate compactor emhlabeni ngepleyiti yayo esisiseko. Kwiinkcukacha ezininzi zemveliso, eli xabiso liboniswa njengamandla e-centrifugal kwaye lilinganiswa ngee-kilonewtons, ezihlala zibhalwa njenge-kN. I-10kN plate compactor ivelisa amandla angaguquguqukiyo kune-30kN reversible plate compactor, kodwa oko akuthethi ukuba umatshini we-30kN ungcono kuyo yonke imisebenzi.
Izinto ezingaphantsi kwepleyiti zibaluleke ngokufanayo nenani elikwileyibhile. Igrabile ekhululekileyo, isanti emanzi, i-asphalt, iibhloko zendlela kunye nomhlaba oxutyiweyo zonke zisabela ngokwahlukileyo ekungcangcazeleni. Izinto ezirhabaxa zihlala kakuhle xa zingcangcazela kuba amasuntswana anokuhamba aye kwindawo eqinileyo. Udongwe olunamathelayo okanye umhlaba omanzi kakhulu unokumelana nokungcangcazela, utsibe phantsi kwepleyiti, okanye wenze nje umatshini uzive ngathi ngequbuliso ugqibe ekubeni yisilwanyana sasefama esinobuqhophololo.
I-kN ikuxelela ukuba ingakanani amandla aguqukayo anokwenziwa yinkqubo yokukhupha umoya. Kubathengi, yindawo yokuqala eluncedo xa uthelekisa iinkcukacha ze-plate compactor. Ii-light forward plate compactors zihlala zisetyenziselwa ukulungiswa okuncinci, iipatio, ukulungiswa kwe-paving kunye neengqimba zegrabile ezincinci. Iimodeli ezinobunzima obuphakathi zilungele iziseko zendlela yokungena, umsebenzi wokulungisa umhlaba kunye nomhlaba oqhelekileyo we-granular. Ii-heavy reversible plate compactors zingcono kwiingqimba ezingaphantsi kwesiseko ezityebileyo, ukulungiswa kwendlela, ukugcwaliswa kwemisele kunye nokusetyenziswa okuqinileyo kwabakhi.
Eyona nto ibalulekileyo kukulinganisa i-plate compactor kN rating nomsebenzi. Ukuba umaleko ubhityile, umphezulu uthambile, okanye umsebenzi usondele kwiindlela ezinqamlezileyo kunye nemiphetho, amandla amaninzi anokwenza kube nzima ukulawula umatshini. Xa usebenza kwiipavers, umzekelo, irabha mat inokuba luncedo ngakumbi kunamandla angaphezulu kuba inceda ekukhuseleni umphezulu. I-kN ephezulu iluncedo xa kufuneka ubunzulu kunye noxinano, kodwa ayisiyonto imangalisayo kuyo yonke indawo.
I-frequency idla ngokuboniswa njenge-VPM, oko kuthetha ukungcangcazela ngomzuzu. Ichaza ukuba umatshini ungcangcazela ngokukhawuleza kangakanani, ngelixa i-kN ichaza ukuba ingakanani amandla afumanekayo. La maxabiso mabini asebenza kunye. I-high-frequency plate compactor inokuba luncedo kakhulu kwiileya ezincinci zesanti, igrabile encinci okanye ukulungiswa kwe-paving kuba ukungcangcazela ngokukhawuleza kunceda amasuntswana ukuba ahlale ngokukhawuleza.
Kwimaleko ezinzulu, amandla adinga ixesha kunye nobunzima ukuze ahambe kwizinto. Kulapho oomatshini abanzima abanamandla amakhulu e-centrifugal badla ngokusebenza ngcono khona. I-plate compactor encinci enee-frequency eziphezulu inokushiya umphezulu ubonakala ucocekile, kodwa umaleko ongezantsi usenokuba ukhululekile ukuba i-lift inzima kakhulu. Yiyo loo nto iinjineli kunye nabaphathi beendawo bengafanele bagwebe umatshini ngokwe-frequency okanye i-kN yodwa. Umhlaba awukhathali ngenani elinye elimangalisayo; usabela kumatshini opheleleyo.
Ubungakanani bepleyiti buchaphazela zombini ukugquma kunye nolawulo. Ipleyiti ebanzi igubungela indawo engakumbi kwiphasi nganye, nto leyo enceda kumhlaba ovulekileyo njengeziseko zendlela, iindawo zokupaka iimoto kunye neendawo ezinkulu zegrabile. Oku kungonga ixesha kuba umqhubi ufuna iiphasi ezimbalwa ukuze agqume umphezulu ofanayo. Nangona kunjalo, ipleyiti ebanzi ayisoloko ilungele kufutshane neendonga, imisele, iikona okanye imiphetho yendlela.
Ipleyiti encinci icotha kwiindawo ezinkulu, kodwa inika umqhubi ulawulo olungcono kwiindawo ezimxinwa kunye nomsebenzi oneenkcukacha. Ubungakanani bepleyiti bukwatshintsha indlela amandla asasazeka ngayo kwizinto. Uvavanyo olufanayo lwe-kN kwipleyiti encinci lunokubonakala luxinene ngakumbi, ngelixa ipleyiti ebanzi isasaza amandla phezu komphezulu omkhulu. Yingakho ubungakanani bepleyiti ye-plate compactor kunye namandla okuxinana kufuneka zithelekiswe rhoqo. Imveliso iluncedo, kodwa kuphela ukuba umatshini usakwazi ukufikelela kwiindawo apho umsebenzi kufuneka wenziwe khona.
Kwiindawo zokuhombisa amatye, iipatio, iindlela zokuhamba kunye nokulungiswa kweziqwenga ezincinci, ulawulo ludla ngokuba lubaluleke ngakumbi kunamandla aphezulu. I-compactor yepleyiti edibeneyo ilula ukuyikhokela kwaye ayinakuphazamisa umphezulu ogqityiweyo. Xa ihombisa phezu kweepavers, imathi yerabha inceda ekunciphiseni ukukrwela, ukuqhekeka kunye naloo manqaku amancinci omphezulu abathengi abawaqaphelayo ngokukhawuleza kunokuba iinjineli zisenza.
Kwiziseko zegrabile, ukulungiswa kwendlela yokungena kunye neziseko ezingaphantsi komhlaba, i-compactor yepleyiti ephakathi enobunzima obuphakathi kunye nobukhulu bepleyiti idla ngokuba lukhetho olusebenzayo. Izinto ezisetyenzisiweyo kufuneka zibekwe kwiileya ezifanelekileyo. Ukuzama ukucutha umaleko ongqindilili ngexesha elinye kudla ngokudala umphezulu obonakala uqinile ngezinto ezikhululekileyo ngaphantsi, okufana nokupeyinta udonga ngaphandle kokulungisa iintanda kuqala.
Kwisiseko sendlela, umva womsele kunye nomsebenzi womkontrakta onzima, i-reversible plate compactor idla ngokufaneleka ngakumbi. Amandla aphezulu e-centrifugal, ubunzima bomatshini obukhulu kunye nentshukumo yokubuyela umva phambili kunceda umqhubi ukuba aqine amaleko amakhulu kwaye asebenze kwiindawo ezifuna kakhulu. Kulapho ukuthelekisa iinkcukacha ze-20kN kunye ne-30kN plate compactor kuba luncedo khona, ngakumbi kubakontrakta, abathengisi kunye neenkampani zokuqeshisa ezifuna izixhobo zeemeko ezahlukeneyo zomsebenzi.
Xa uthelekisa iinkcukacha ze-plate compactor, qala ngezinto ezifunekayo, hayi ngomatshini. Buza ukuba zeziphi izinto ekufuneka ziqiniswe: i-gravel, isanti, i-asphalt, ii-pavers, umhlaba oxutyiweyo okanye i-trench backfill. Emva koko jonga ubukhulu beleya, indawo yokusebenza ekhoyo kunye nokugqitywa okufunekayo. Emva koko, thelekisa i-kN, i-frequency, ubungakanani beplate, ubunzima bomatshini, isantya sokuhamba kunye nezixhobo eziluncedo ezifana netanki yamanzi, i-raber mat, isiphatho sokusonga kunye nesakhelo sokuphakamisa.
Isigqibo esihle sokuthenga silandela ulandelelwano olulula. Okokuqala, khetha uhlobo lomatshini: i-forward plate compactor yomsebenzi olula ukuya kophakathi, okanye i-reversible plate compactor yee-layers ezinzima kunye nemisebenzi yabakhi abaqinileyo. Okwesibini, jonga ukuba amandla okuxinana afanelekile na kwizinto kunye nobunzulu. Okwesithathu, qinisekisa ukuba ubungakanani beplate buhambelana nendawo. Kwiinkampani zokuqeshisa kunye nabathengisi, ukufikelela kulondolozo, iindawo ezisele, ukhetho lwenjini kunye nokulula kokuthutha kufuneka kuqwalaselwe kuba umatshini olula ukuwusebenzela ufumana ukuthenjwa ngokukhawuleza kunowo ubonakala uqinile ephepheni kuphela.
Hayi. I-kN ephezulu inceda ngezinto ezinzulu okanye ezixineneyo, kodwa ayisoloko ingcono kwiileya ezincinci, iipavers okanye ukulungiswa kwe-asphalt. Isiphumo esifanelekileyo sixhomekeke kwi-kN, i-frequency, ubungakanani bepleyiti, ubunzima bomatshini, uhlobo lwezinto kunye nolawulo lomqhubi.
Amandla eCentrifugal ngamandla aguqukayo adalwe yi-exciter ejikelezayo ngaphakathi kwi-plate compactor. Abathengi badla ngokuyijonga njengexabiso lamandla okuxinana, kodwa ukusebenza kokwenyani kuxhomekeke kwindlela loo mandla athunyelwa ngayo kwi-plate ukuya kwizinto.
I-frequency kunye ne-kN zenza imisebenzi eyahlukeneyo. I-frequency ibonisa ukuba umatshini ungcangcazela ngokukhawuleza kangakanani, ngelixa i-kN ibonisa ukuba inamandla angakanani na enokuyivelisa. I-thin granular layers zihlala zixhamla kwi-frequency ephezulu, ngelixa i-deep layers zihlala zifuna ubunzima obungakumbi kunye nokudluliselwa kwamandla aqinileyo.
Ipleyiti enkulu ingcono ekugqumeni iindawo ezivulekileyo ngokukhawuleza. Ipleyiti encinci ingcono kwiimphetho, ukulungisa amabala, iipavers kunye neendawo ezimxinwa. Ubungakanani bepleyiti obufanelekileyo buxhomekeke ekubeni umsebenzi ufuna isantya, ulawulo okanye ukufikelela.
Ubunzulu bokuxinana buxhomekeke kubunzima bomatshini, umlinganiselo we-kN, ukuphindaphinda, ubungakanani bepleyiti, uhlobo lomhlaba, ukufuma kunye nobukhulu bomaleko. Ii-compactors zepleyiti ezincinci ezingaphambili zilungele umsebenzi ongaphantsi ukuya kophakathi, ngelixa iimodeli ezinzima eziguqukayo zingcono xa kuxinana nzulu.
