Umhlinzeki wemishini yokwakha wezixazululo zemishini yokwakha iminyaka engama-30.
Ukukhetha i-blade yedayimane akukhona nje ukukhetha ububanzi obufanele nokwethemba ukuthi i-saw izokuthethelela. I-blade kufanele ifane nezinto zokwakha, i-saw, ukujula kokusika kanye nezimo zendawo yokusebenza. I-concrete, i-asphalt kanye nama-slab aqinisiwe konke kungabonakala “njengezinto eziqinile” uma ukude, kodwa ku-blade yedayimane kuziphatha ngendlela ehlukile kakhulu.
Umthetho oyisisekelo ulula: izinto eziqinile ngokuvamile zidinga isibopho esithambile, kuyilapho izinto ezithambile nezirhabaxa zidinga isibopho esiqinile. I-Norton Abrasives ichaza ukukhethwa kwesibopho se-blade yedayimane nge-logic efanayo yezibopho eziphambene: izibopho eziqinile zifanela izinto ezithambile zokuhuzuka njenge-asphalt, kuyilapho izibopho ezithambile zifanela ukhonkolo oqinile. Ekuqaleni kuzwakala sengathi kuphambene, kodwa kunengqondo uma ukhumbula ukuthi izibopho zensimbi kumele ziguge ngesivinini esifanele ukuze kuvezwe amadayimane amasha.
Umthetho osheshayo: khetha i-blade ngezinto kuqala, bese uqinisekisa uhlobo lwebhondi, ukwakheka kwengxenye, usayizi weserha, ukujula kokusika kanye nokusetshenziswa okumanzi noma okomile.
| Izinto | I-Blade Enconyiwe | Uhlobo lwebhondi | Indlela Engcono Kakhulu Yokusika |
|---|---|---|---|
| Ukhonkolo olungisiwe | I-blade yedayimane yekhonkrithi ehlukaniswe ngezigaba | Isibopho esithambile kuya kwesiphakathi | Kumanzi noma komile |
| Ukhonkolo oqinile | I-blade yekhonkrithi yesibopho esithambile | Isibopho esithambile | Kukhethwa okumanzi |
| Ukhonkolo oluhlaza | Itshe eliluhlaza okotshani noma i-blade yokungena kusenesikhathi | Isibopho esiqinile | Kuncike ohlotsheni lwesaha |
| I-Asphalt | I-blade yedayimane ye-asphalt | Isibopho esiqinile | Kumanzi noma komile |
| I-slab eqinisiwe | I-blade yedayimane eqinisiwe yekhonkrithi | Isibopho esithambile kuya kwesiphakathi | Kukhethwa okumanzi |
| Ukhonkolo one-rebar | I-blade ehlukaniswe nge-laser | Isibopho esithambile kuya kwesiphakathi | Kukhethwa okumanzi |
| I-patch yekhonkrithi ne-asphalt | I-blade ehlanganisiwe elinganisiwe | Isibopho esiqinile esimaphakathi | Ukusika okufushane okuxubile kuphela |
Sebenzisa leli shadi njengesihlungi sokuqala. Uma ufuna ukuqhathanisa okujulile phakathi kwezinto zokwakha imigwaqo, funda lo mhlahlandlela ku- ukukhetha i-blade yesaha likakhonkolo vs i-asphalt Ukukhetha i-blade yokugcina kusancike kububanzi be-blade, usayizi we-arbor, amandla esaha, ukujula kokusika, isilinganiso se-RPM kanye nokuthi amanzi ayatholakala yini.
Ikhonkrithi eqinisiwe ilukhuni, ikakhulukazi uma ine-aggregate eningi. Iyathuntubeza amadayimane avele obala, ngakho-ke isibopho kumele siguge ngokwanele ukuze siveze amadayimane amasha okusika. Ama-diamond blade guides avame ukuphatha ikhonkrithi engama- 3,000 psi noma ngaphansi njengento ethambile kanye nekhonkrithi engama- 6,000 psi noma ngaphezulu njengento eqinile. Lokho kunikeza onjiniyela nabathengi indawo ewusizo yokuqala ngaphambi kokuhlola uhlobo lwe-aggregate kanye nokuqinisa.
I-asphalt ithambile kunekhonkrithi elungisiwe, kodwa iyakhahlazeka kakhulu. Isihlabathi kanye ne-aggregate e-asphalt kungadla umongo we-blade uma kusetshenziswa i-blade engafanele. Yingakho i-blade yedayimane ye-asphalt ivame ukusebenzisa isibopho esiqinile kanye nokuvikelwa okungaphansi. Ngolimi olulula lwendawo yokusebenza, i-asphalt akuyona "ikhonkrithi elula." Iwumshini wokugaya i-blade ogqoke izingubo zomgwaqo.
Ama-slab aqinisiwe anezela enye inkinga: insimbi. I-blade yedayimane yekhonkrithi ene-rebar idinga izingxenye eziqinile, ingcindezi yokudla eqinile kanye nokupholisa okuhle. Ukusika okumanzi ngokuvamile kuyindlela ehlakaniphile ngoba ukuthintana nensimbi kudala ukushisa ngokushesha.
| Uhlobo lwebhondi | Okuhle Kakhulu Kwaba | Uma Kusetshenziswe Kabi |
|---|---|---|
| Isibopho esithambile | Ikhonkrithi eqinile, i-aggregate eqinile, ikhonkrithi eqinisiwe | Igqoka ngokushesha kakhulu e-asphalt |
| Isibopho esiphakathi | Umsebenzi ojwayelekile wekhonkrithi kanye nomsebenzi oxubile | Kuyamukeleka, kodwa akuhlali kukuhle |
| Isibopho esiqinile | I-Asphalt, ukhonkolo oluhlaza, ibhlogo elihudulayo | Ingagcotshwa kukhonkrithi eqinile |
I-Aggregate nayo ibalulekile. Ezinye iziqondiso zokukhetha ama-blade zihlukanisa i-aggregate enkulu kune -3/4 intshi njenge-aggregate enkulu, kuyilapho i-aggregate engaphansi kwe -3/8 intshi kulula ukuyisika kodwa ingase iguge i-blade ngokushesha. Yingakho ama-slab amabili anamandla afanayo okucindezela esengasika ngendlela ehlukile. I-concrete inomqondo wokuhlekisa, futhi ivame ukuyifihla ngaphakathi kwe-aggregate.
Uma ukhonkolo uqinile, qala nge-blade yedayimane yekhonkolo ehlukanisiwe. Uma ukhonkolo uqinile noma i-blade iqala ukucwebezela, qhubekela ebophweni elithambile. Uma ukhonkolo uthambile futhi uhudula, qhubekela ebophweni eliqinile. Ukuze uthole izinketho zamathuluzi ahlobene, ungahlola futhi inkemba yesaha likakhonkolo ikhasi.
Ukukhetha i-saw blade yekhonkrithi kufanele futhi kuhambisane ne-saw. Isibonelo, Imininingwane ye-Husqvarna K 770 Bhala i-blade engamasentimitha angu-14 , ukujula kokusika okuphezulu okungamasentimitha angu-5 , ukuphuma okungu-5 hp kanye nesivinini esiphezulu esingu-18,000 fpm . Lezo zinombolo ziyisikhumbuzo sokuthi ukukhetha i-blade akugcini nje ngezinto ezibonakalayo. Ububanzi, usayizi we-arbor kanye nesilinganiso sesivinini kumele kufane nomshini.
Ukuze usike i-asphalt, sebenzisa i-blade yedayimane ye-asphalt ezinikele. Kufanele ibe nesibopho esiqinile, i-slurry clearance enhle kanye nokuvikelwa kokusikwa okungaphansi. UNorton uphawula ukuthi ukusikwa okungaphansi kungaholela ekulahlekelweni yizingxenye, futhi uncoma ukuvikelwa kokusikwa okungaphansi noma ukugeleza kwamanzi okwandisiwe lapho izinto ezihuquzelayo zihlasela khona insimbi.
I-blade ejwayelekile eqondene ne-asphalt ibonisa ukuthi la mathuluzi angaba akhethekile kangakanani. I-CMT ibala i-asphalt blade engu-300 mm ngesigaba esivikelwe ngaphansi kwe-8 mm , imbobo engu-20 mm kanye nesilinganiso esiphezulu se-rpm esingu-6,400 , futhi siyiphawula njengengafaneleki kukhonkolo noma kukhonkolo okuqinisiwe. Ngemisebenzi yokuhamba nge-asphalt, hlanganisa i-blade nomsiki ofanele, njenge- umsiki wekhonkrithi kaphethiloli wokusika i-asphalt kanye ne-concrete pavement .
Uma ufuna ukhonkolo oluqinisiwe, sebenzisa i-blade elinganiselwe ukuthintana ne-rebar. Isibopho esithambile kuya kwesiphakathi sisiza i-blade ukuthi iqhubeke nokusika ukhonkolo oqinile, kuyilapho ukwakhiwa okuneziqephu eziqinile kusiza ukuthi isinde ekushiseni nasekushayweni lapho kuvela insimbi. Iziqephu ezifakwe nge-laser zivame ukuthandwa uma kusetshenziswa ukusika okunzima ngoba uxhumano lweziqephu luqina ngaphansi kwezimo ezinzima.
Ungaphoqi i-blade uma ifika e-rebar. Gcina ukudla kuzinzile, sebenzisa amanzi uma kungenzeka futhi ugweme ukujikisa i-saw esikiwe. Uma i-blade iqala ukubhema, i-saw iqala ukugxumagxuma, noma umqhubi eqala ukuxoxisana nomshini, yima bese uhlola ukusetha.
Ukusikwa okumanzi akukhona nje kuphela ngokuphila kwe-blade. Isiqondiso se-silica sokwakhiwa kwe-OSHA ibeka izinga lesenzo se-silica esicwebezelayo esicwebezelayo ku- 25 μg/m³ kanye nomkhawulo wokuvezwa ovunyelwe ku- 50 μg/m³ , kokubili njengesilinganiso sesikhathi samahora angu-8. Lokho kwenza ukusika okumanzi kube yisinqumo sokulawula uthuli kanye nesinqumo sokupholisa.
Ukusika okomile kuyasiza ekusikeni okufushane kanye nomsebenzi wokulungisa, kodwa kuphela nge-blade elinganiswe ukusetshenziswa okomile. Ungalokothi usebenzise i-blade emanzi kuphela. Lokho akuyona indlela esheshayo yokushisa ngokweqile, ukugqwala kanye ne-blade eba yinsimbi elahliwe ebiza kakhulu ngokuzumayo. Ukuze uthole ukuqhathanisa okujulile, funda ukusika ukhonkolo okumanzi vs okomile .
I-blade enhle esaheni elingalungile isanikeza imiphumela emibi. Ngaphambi kokusika, qinisekisa ububanzi be-blade, usayizi we-arbor, i-RPM ephezulu, ukujula kokusika, ukuphakelwa kwamanzi kanye namandla esahe. Uma umsebenzi uhilela ukusika okude kwemigwaqo, ukulungiswa komgwaqo noma ukufaka imisele, lo mhlahlandlela umayelana indlela yokukhetha isaha lomgwaqo elifanele lokusika ukhonkolo kanye ne-asphalt isinyathelo esilandelayo esingcono.
Kwabakhi abaqhathanisa imishini, umhlahlandlela wokugcina wabasiki bekhonkrithi nemishini yokusika imigwaqo inikeza umongo owengeziwe ngohlobo lomshini, ukujula kokusika kanye nomsebenzi womgwaqo. Uma udinga umbono obanzi wokusetshenziswa, isihloko esiku- izinzuzo zesaha lomgwaqo zokulungisa ukhonkolo, i-asphalt kanye ne-pavement futhi kuyinkomba yangaphakathi ewusizo.
Iphutha lokuqala ukusebenzisa i-blade eyodwa ukwenza ukhonkolo, i-asphalt kanye nama-slab aqinisiwe. Elesibili ukunganaki ukuqina kwe-bond. Elesithathu ukusola isaha lapho inkinga yangempela iwukugqokwa kwe-blade, i-RPM engalungile, ukupholisa okubi noma ukufana kwezinto ezingalungile.
Uma i-blade yedayimane iyeka ukusika, hlola isibopho, izinto zokwakha, isivinini se-saw kanye nokunikezwa kwamanzi ngaphambi kokusunduza ngamandla. I-blade enhle kufanele inqume ngokucindezela okuqhubekayo. Uma kufanele ulwe ne-saw, i-blade cishe ikutshela okuthile. Ngaleyo nkinga ethile, sebenzisa lo mhlahlandlela ku- ukugqokwa kwe-blade yedayimane nokuthi kungani i-blade iyeka ukusika .
Sebenzisa ishadi lokukhetha i-blade yedayimane ukuze unciphise ukukhetha, bese uqinisekisa izinto ezine: izinto zokwakha, isibopho, i-saw match kanye nendlela yokusika. Ukuze uthole ukhonkolo, cabanga ngamandla kanye ne-aggregate. Ukuze uthole i-asphalt, cabanga ngokuguguleka kanye nokuvikelwa kokunqunywa. Ukuze uthole ama-slab aqinisiwe, cabanga ngensimbi, ukushisa kanye nokupholisa.
I-blade yesokudla ayigcini nje ngokusika ngokushesha. Isebenza kahle, ihlala isikhathi eside, inciphisa isikhathi sokungasebenzi futhi yenza umqhubi abukeke sengathi uhlele konke kusukela ekuqaleni.
