Emkhakheni wokwakha, ukunemba nokusebenza kahle kubaluleke kakhulu, ikakhulukazi uma kukhulunywa ngomsebenzi wekhonkrithi. Ubuso bekhonkrithi obulinganiswe kahle futhi obuhlanganisiwe kahle bakha isisekelo sezakhiwo ezihlala isikhathi eside, kusukela phansi kwezimboni kuya emigwaqweni yokuhlala. Phakathi kwezinto ezintsha ezishintshe ukuqeda ikhonkrithi, umshini we-screed wekhonkrithi ye-laser kaphethiloli uvelele njengoshintsha umdlalo. Lo mshini othuthukisiwe uhlanganisa amandla, ukunemba, kanye nokuhamba ukuze ulethe imiphumela emihle kakhulu, okwenza kube yinto ebalulekile ezindaweni zokwakha zesimanje.
Enhliziyweni yayo,umshini we-screed we-laser concrete odlidlizayoiklanyelwe ukwenza imisebenzi emibili ebalulekile: ukulinganisa ukhonkolo osanda kuthululwa kanye nokususa amabhamuza omoya ngokudlidliza. Ngokungafani nezindlela zendabuko zesandla ezincike emandleni angokomzimba kanye nokwahlulela okubonakalayo, lo mshini usebenzisa ubuchwepheshe ukuqinisekisa ukuvumelana. Ukuhlanganiswa kohlelo lwe-laser yikho okulwenza luhluke—lesi sici sisebenza njengesiqondiso esiqondisayo, sivumela i-screed ukuthi igcine izinga eliqondile ezindaweni ezinkulu. Kungakhathaliseki ukuthi isebenza phansi kwendlu yokugcina impahla engamamitha-skwele ayi-100 noma ibanga elide lomgwaqo omkhulu, isiqondiso se-laser siqinisekisa ukuthi ubuso bekhonkolo bunamathela ekuphakameni okuqondile okuchazwe ezinhlelweni zephrojekthi.
Ukusebenza komshini kusekelwa yizingxenye eziningana ezibalulekile, ngayinye idlala indima ebalulekile ekusebenzeni kwayo. Injini kaphethiloli isebenza njengomthombo wamandla oyinhloko, inikeza i-torque ephezulu kanye nokuthembeka. Lokhu kunenzuzo ikakhulukazi ezindaweni zokwakha ezikude lapho ukufinyelela kukagesi kulinganiselwe khona, njengoba kuqeda isidingo sezintambo noma amajeneretha. Izinjini zikaphethiloli zesimanje ezisetshenziswa kule mishini zivame ukwakhiwa ukuze zisebenzise kahle uphethiloli kanye nokukhishwa okuphansi komoya, okuhambisana nezindinganiso zemvelo ezikhulayo embonini yokwakha.
Ipuleti le-screed elidlidlizayo elinamathiselwe enjinini, eliza ngobude obuhlukahlukene ukuze livumelane nosayizi bephrojekthi abahlukene. Ipuleti liyadlidliza ngemvamisa elawulwayo—ngokuvamile phakathi kokudlidliza okungu-4,000 kuya ku-6,000 ngomzuzu—kuye ngokuthi ingxube yekhonkrithi injani kanye nokuvumelana okufiswayo. Lokhu kudlidliza kubalulekile ngoba kuqinisa ikhonkrithi, kuphoqe amabhamuza omoya ukuba akhuphukele phezulu futhi aphume. Ngaphandle kokuqiniswa okufanele, amaphakethe omoya angenza ukhonkrithi ube buthaka, okuholela ekuqhekekeni nasekuhlulekeni kwesakhiwo ngokuhamba kwesikhathi. Isenzo sokudlidliza sisiza futhi ukuxazulula i-aggregate ngaphakathi kwengxube, ukuqinisekisa ukusatshalaliswa okufanayo okuthuthukisa amandla.
Okuhambisana nepuleti elidlidlizayo yi-laser receiver kanye nesistimu yokulawula. I-laser transmitter, ebekwe endaweni eqondile endaweni yokwakha, ikhipha umsebe we-laser ovundlile osebenza njengomugqa wokubhekisela. I-receiver, efakwe emshinini we-screed, ithola lo msebe bese ithumela izimpawu ohlelweni lokulawula. Uma i-screed iphambuka emgqeni we-laser—ngisho nangengxenye encane ye-intshi—uhlelo lulungisa ukuphakama kwepuleti ngokuzenzakalelayo noma luxwayise umqhubi, luqinisekisa ukuthi indawo ihlala isezingeni elifanele. Leli zinga lokunemba cishe akunakwenzeka ukulifinyelela ngamathuluzi esandla njenge-screeds yesandla noma i-bull floats, evame ukwenza amaphutha kubantu.
Enye yezinzuzo ezibaluleke kakhulu ze-umshini we-screed we-laser wekhonkrithi odlidlizayoukusebenza kahle kwayo. Umsebenzisi oyedwa angakwazi ukumboza izindawo ezinkulu ngesikhathi esincane kakhulu kunesikhathi esingathatha iqembu esebenzisa izindlela ezenziwe ngezandla. Isibonelo, ukulinganisa i-slab engamamitha-skwele angu-500 kungathatha usuku ngamathuluzi endabuko, kodwa umshini ungaqeda umsebenzi ofanayo ngamahora ambalwa nje. Lokhu akugcini nje ngokunciphisa izindleko zabasebenzi kodwa futhi kusheshisa isikhathi sephrojekthi, okuvumela izigaba zokwakha ezilandelayo ukuthi ziqale kusenesikhathi. Ngaphezu kwalokho, ukuhamba komshini—ngokuvamile kusekelwa amasondo noma ama-skid—kwenza kube lula ukujika, ngisho nasezindaweni ezingalingani.
Ukuqina kungenye inzuzo ebalulekile. Le mishini yakhelwe ukumelana nezimo ezinzima zezindawo zokwakha, enezinhlaka eziqinile, izinto ezingagqwali, kanye nezembozo zokuvikela zezingxenye ezizwelayo njenge-laser receiver. Izinjini zikaphethiloli zenzelwe ukusetshenziswa kanzima, ezidinga ukulungiswa okuncane uma zisetshenziswa ngokweziqondiso. Ukuhlolwa njalo kwamafutha enjini, izihlungi zomoya, kanye nezindlela zokudlidliza ngokuvamile kwanele ukugcina umshini usebenza kahle iminyaka eminingi.
Ukuguquguquka komshini we-gasoline laser concrete vibrating screed owenza ukuthi ufanelekele izinhlelo zokusebenza eziningi ezahlukene. Uvame ukusetshenziswa kumaphrojekthi ezentengiselwano afana nezitezi zezitolo ezinkulu, imigwaqo yezindiza, kanye nama-workshop efektri, lapho izindawo ezinkulu neziyisicaba zibalulekile khona. Ekwakhiweni kwezindlu zokuhlala, ubaluleka kakhulu ekuthululweni kwemigwaqo, ama-patio, kanye nezitezi ezingaphansi komhlaba, okuqinisekisa ukuqeda okubushelelezi okuthuthukisa ubuhle kanye nokusebenza. Ngisho nasemaphrojekthini akhethekile afana nama-bridge decks noma amagalaji okupaka, ukunemba komshini kusiza ukuhlangabezana nezindinganiso zobunjiniyela eziqinile.
Ukuze kuthuthukiswe ukusebenza kahle komshini, opharetha kumele balandele izinqubo ezifanele. Ngaphambi kokusebenzisa, umshini wokudlulisa i-laser kufanele ulinganiswe futhi ubekwe endaweni ezinzile ukuze kugwenywe ukuphazamiseka. Ingxube yekhonkrithi kumele futhi ilungiswe kahle—ngesilinganiso esifanele samanzi nosimende—ukuqinisekisa ukuthi igeleza kahle ngaphansi kwe-screed. Ngesikhathi sokusebenza, opharetha kufanele ashukumise umshini ngesivinini esizinzile, okuvumela ipuleti elidlidlizayo ukuthi lihlanganise ukhonkrithi ngokulinganayo. Ukudlula okugoqene ngamasentimitha ambalwa kusiza ukuvimbela izikhala, kuyilapho ukulungisa imvamisa yokudlidliza ngokusekelwe ekusebenzeni kahle kokhonkrithi kuqinisekisa ukuqina okuhle.
Njenganoma yimuphi umshini, umshini wokudlidliza we-laser concrete we-gasoline udinga ukulungiswa njalo ukuze usebenze kahle kakhulu. Injini kaphethiloli kufanele inakekelwe ngokwesimiso somkhiqizi, ngokushintsha uwoyela, ukushintshwa kwe-spark plug, kanye nokuhlanza izihlungi. Indlela yokudlidliza, okuhlanganisa ama-bearings kanye nezisindo ezingavamile, kufanele ihlolwe ukuthi ayigugi yini, njengoba izingxenye ezonakele zinganciphisa ukusebenza kahle kokudlidliza. Isamukeli se-laser kanye ne-transmitter kumele zigcinwe zihlanzekile futhi zilinganiswe ukuze kugcinwe ukunemba, njengoba ukungcola noma ukungalungi kungaphazamisa isignali ye-laser.
Ekuphetheni, umshini wokudlidliza we-laser concrete vibrating screed we-gasoline uchaze kabusha ukulinganisa kanye nokuqina kwekhonkrithi embonini yokwakha. Ngokuhlanganisa amandla enjini kaphethiloli, ukunemba kwesiqondiso se-laser, kanye nokusebenza kahle kokudlidliza okulawulwayo, uletha imiphumela esezingeni eliphezulu futhi engabizi kakhulu. Amandla ayo okusingatha izindawo ezinkulu ngokungasebenzi kahle, ukunciphisa amaphutha, nokusheshisa isikhathi sephrojekthi kwenza kube ithuluzi elibalulekile ekwakheni kwesimanje. Njengoba ubuchwepheshe buqhubeka nokuthuthuka, singalindela ukuthuthuka okwengeziwe kule mishini—njengokuzenzakalela okuthuthukisiwe noma ukuhlanganiswa nezinhlelo zokuphatha amaphrojekthi edijithali—okuqinisa indima yabo njengesisekelo sokwakha ikhonkrithi. Kwabakhi nabakhi abahlose ukuletha izindawo eziqinile, ezisezingeni, neziqediwe ngobungcweti, ukutshala imali emshinini wokudlidliza we-laser concrete vibrating screed akuyona nje ukukhetha kodwa isinqumo esihlakaniphile esizuzisayo ngokuhamba kwesikhathi.
