Kungani Ukulungiswa Kokusabela Kwamabhuloyi Kuyinxenye Ebalulekileyo Ekusebenzeni Kwebhuloyi YeDiamond KwiReinforced Concrete

Iziphumo Zokusabela Okungahle: Ukuglazwa, Ukudla Kakhulu, Nokwephula Kwangaphambili Kwebhuloyi

Xa izindlela zokunika izinto zokudla azidaliwa ngendlela efanelekileyo, izibobo ze-diamond ziyenzela imibuzo emithathu ekusobala kakhulu eyenza ubude bokuphila babo kube yizikhathi eziphindwe kabili. Okokuqala kukhona ukuglazwa, emva koko ukwephukela kwakhona, kulandela ukupheleka kwezibobo ngokushesha. Le miba ihlangana njalo. Uma umuntu unikela ngokushesha kakhulu, akukho nqubo yokubamba okwanele ukuwephesa ikonkreti. Kutheni okulandelayo? Ukuxhasana kwenza ukuthi ukwephukile kwenze isitshalo esivumelana sokudla esihlangothini esenza ukuthi sizange sihlale sicutshunge ngendlela efanele. Ngokwesinye isikhathi, ukuthinta kakhulu kwenza ukuthi kube khona ukuthintana okuningi kakhulu kwezibobo, ikakhulukazi xa kusebenziswa konkrethe enenziwe ngaphezu kuka-2% yesithayi. Lokhu kuyenza ukuthi ikore iphinde, amasegment ayekwa, futhi ekugcineni kuyaphula umfanekiso wokudliwa ngokugcwele. Abasebenzi abaningi abanengqondo bahlola umbala wezinkawusha njengendlela yokuhlola. Izinkawusha ezimnyama zibonisa ukuthi zonke izinto zihamba kahle. Kodwa uma izinkawusha ziyohla emhlophe noma dheli, lokhu kuyisigina sokuthi kunezinto ezinempazamo kakhulu, sisigina sokuthi kufuneka usuke ngokushesha kakhulu.

Ukuthi Kanjani Ithekwane Ethelelweyo Yekonkreti Ebekiwe Ngokudluliselana Kukhuniwa Ukuguqula Kwesilinganiso Sekhuni

Ukwakheka kokhonkolo oqinisiwe okuyinhlanganisela kudala izinselele ezinkulu lapho kusikwa. Ngokuyinhloko, sinama-agregates agqwalile phakathi kuka-Mohs 3 kuya ku-5 agxunyekwe ku-cement paste, konke kuxubene nezinsimbi ezinzima kakhulu ezinamandla e-Mohs 7.5 kuya ku-8. Lokhu kuhlanganisa kuholela ekushintsheni okuzumayo kwemishini okuphazamisa izinga lokudla eliqhubekayo. Lapho amathuluzi okusika eshaya lezo zinhlayiya eziqinisiwe ezakha cishe u-5 kuya ku-15% wezingxenye eziningi, ukumelana kuyakhuphuka ngokuphindwe kathathu kunezinga elijwayelekile. Lolo hlobo lwamandla lubeka ama-blade engozini yangempela yokuqhekeka noma yokulahlekelwa amadayimane ngokuphelele. Ukhonkolo ngokwawo ungakwazi ukubhekana nokudla okusheshayo, kodwa noma nini lapho kukhona ushintsho lwensimbi, ingcindezi idinga ukwehla ngokushesha. Ukuhlolwa okusebenzayo kubonisa ukuthi opharetha ababona ukuzamazama kushintsha futhi balungise amazinga okuphakelayo kungakapheli isigamu somzuzwana ngemva kokubona ukwanda kokuphakama, bavame ukushintsha ama-blade cishe ama-40% kaningi kunalabo abanamathela ekubekweni kwejubane eliqinile kulo lonke umsebenzi.

Ukwenza Kwesayensi Ngekulungiswa Kwehafu YokuFeeda: Ubuchwepheshe Bekomphutha, I-RPM, Nezinhlelo Zeblade

Ukusobala Kwehafu: Kungani Ukubuchwepheshe Okuncane Kukudinga Izindleko Ezimnandi (Ngaphandle Kweqiniso)

Kuningi okwesekwe yizinyamazane: xa kusebenzisa konkrethi embile noma ebuthuthukile (konke okungenaphansi kwe-3,000 PSI), ukuchukumisa kancane kusebenza ngokulungile kukuqinisekisa ngokukhetshele. Lokhu kuyindlela, konkrethi embile akakhathaze ngokwanele, kodwa akakwazi ukwakha ngokwanele ukuphazanyiswa okwadlulelwe kumasegment amadhamu nokuvulela amaxeshe akuphucukileyo. Xa akukho nokukhethsele okwanele emva kwesekwa, amadhamu angahlala ajikele ngaphandle kokugwinya ngendlela efanelekileyo, okwakha kakhulu ukudla kunezindlela zokudla kakhulu futhi kugcine kakhulu ukudla kwezindlela zokudla. Izihloko ezivela kumelabhu zibonisa lokho abasebenzi abaningi abanaziwayo - ukukhethsele kakhulu kwezindlela zokudla kwekonkrethi embile kugcine kakhulu ukudla kweblade ngaphaya kwe-40% kanti kugcine kakhulu ukudla kwezindlela zokudla ngeminyaka ezimbili. Ngokulungile, kufanele ukuthula izindlela zokudla ngokungu-15 kuze kungu-20% kusukela kuthinta kwabafundiwa xa kusebenzisa konkrethi okungafuthi, okungafuthi, noma okubonisa izinkomba zokucindezela. Kufanele ukuthinta ngendlela efanelekileyo kuye kakhulu kukuqinisekisa ukuthinta kakhulu kulezi zimo.

I-RPM—Ukuvumelanisa Kusuka: Indlela Ezingathathu Yokulungiselela Okuphathelene Nokukhipha Kwizimo Nezimo Ezihlala Ngazo

Ukuvumelanisa i-RPM nesilinganiso sesuka sibaluleke kakhulu ekuphileni kwesimo sezindlela nokukhipha ngokuefficiency. Indlela eziqinisekisiweyo ezinezinyathelo ezithathu yokulungiselela iyagcina ukuba yinto efanayo phakathi kweminyaka yonke:

1. Dala i-RPM yekhasi : Luthela ubude bendawo yesikibane kwi-specifications zomsebenzisi wesikibane—ungahlali phezu kwe-RPM enikeziwe ngokumelene.
2. Lungisa ingxenye yesuka : Shintshela pansi de kude liphinde likhuphe ngendlela efana nempahla (ngaphandle kwezimo) noma isiluri esigugu, esimbi (nezimo).
3. Funda impendulo yethemperetsha : Ekukhipheni ngaphandle kwezimo, sinxepha i-RPM ngama-20% ngokuqala kumaqondo wokushintsha komusa (ukublula noma ukushintsha kwegolide); ekukhipheni nezimo, nyusa isilinganiso sesuka uma isiluri sikhula siluhlaza noma sibukeka sikhazimula—lokhu kusho ukuthi kusekelwe kancane futhi akusekeli kakhulu.

Ukuqinisekiswa kwensimu kubonisa ukuthi ukunamathela kule nqubo kwandisa ukuphila kwe-diamond blade ngo-25% lapho kusikwa ukhonkolo oqinisiwe.

Amasu wokulungisa isilinganiso sokudla lapho usika i-rebar yensimbi

Ukuphathwa Kwezikhukhula Zomthwalo: Ukuguqulwa Kwesilinganiso Sokudla Esisikhathi Sangempela Ngesikhathi Sokuzibandakanya Kwe-Rebar

Lapho umshini ushaya ibha yensimbi, kubangela ukuqhuma okukhulu komthwalo okungaba ngaphezu kokuphindwe kathathu kunokujwayelekile. Empeleni lesi ngesinye sezizathu eziyinhloko ezenza izingxenye ziqale ukubola futhi amabhondi aqale ukwehluleka ngokuhamba kwesikhathi. Ukuze kulungiswe le nkinga kahle, izisebenzi kudingeka zinciphise ngokushesha ijubane lokudla kodwa zingazivali ngokuphelele izinto. Uma bebona izimpawu ezinjengokushintsha kokudlidliza, ukwehla kwephimbo lomsindo, noma ukubona udaka oluxubene nezingcezu zensimbi nezinhlansi ezindizayo, kufanele banciphise ingcindezi yokudla cishe ngamaphesenti angu-40 kuya kwangu-50. Ngesikhathi esifanayo, ukugcina ama-RPM aphakathi kuka-2 500 no-3 000 kusiza ukugcina amandla okusika ngaphandle kokubangela umonakalo ngenxa yokwehla ngokushesha. Ngokwezivivinyo zasensimini ezanyatheliswa kuyi-Construction Tech Journal ngonyaka odlule, le ndlela inciphisa izinkinga zokuqhekeka cishe izingxenye ezimbili kwezintathu uma iqhathaniswa nokugijima ngesivinini esiqinile ngaso sonke isikhathi.

Ukuphepha kuqhathaniswa nokusebenza kahle: Isiqondiso Esisekelwe Ebufakazini Ngokuqedwa Ngokuqhutshwa Ngokuqhubekayo Kwe-Rebar

Ukuhlaziywa okuphelele kwezingxenye zangempela zokhonkolo oqinile ezingu-1 200 kwembula ukuvumelana okucacile phakathi kokuphepha, ukuphila isikhathi eside kwezingxenye zokwakha nokukhiqiza:

Ukulungisa amazinga okuphakelayo abe ngu-15 kuya ku-15 cm ngomzuzu kuyilapho ugcina umshini usebenza kubonakala kuwukulinganisela okuhle kakhulu emisebenzini eminingi. Le ndlela igcina ukushisa kwethuluzi lokusika kulawulwa, kuhlale kungaphansi kuka-300°C lapho i-graphite iqala ukwakheka khona emabhejini. Le nqubo empeleni iqeda umsebenzi ngokushesha okungamaphesenti angu-27 uma iqhathaniswa nokuyeka ngokuphelele phakathi kwezingxenye, futhi ingaphansi kwengcindezi eseceleni ezintweni lapho konke kuqondaniswe kahle phezulu naphansi. Nokho, lokho okwenzekayo kubalulekile lapho opharetha benganaki ukubeka indawo ngokuqondile phakathi nalezo zinguquko ngokusebenzisa imigoqo yokuqinisa. Ngisho nokuphambuka okuncane kungenza izingxenye ziguge ngokushesha ngokuphindwe izikhathi ezingu-3,5 ngoba umthwalo usakazwa ngokungafani ebusweni bokusika.

Amasu okuhlola okuqinisekisiwe okuhlolwa kwe-operator ukuze kulungiswe izinga lokudla elihambisanayo ezimweni zasendle

Ukufunda ukuguqulwa kwesilinganiso sokudla kukhonkolo oqinisiwe kudinga ukuqaphela izinzwa, ama-reflexes alinganisiwe, nokulawula okuguquguqukayo, hhayi ukunamathela ngokuqinile kumazinga ajwayelekile. Abasebenza abanolwazi bathembela ekubuyiseleni okuhlanganisiwe:
