Izinto ezisetshenziswayo ekwakhiweni kwephrojekthi ehlukene zihlukile, ngakho-ke iyunithi yokwakha izokhetha ukusetshenziswa kwezinto ezingavuthiwe ngokuya ngesimo sangempela. Ngokugandaywa komgwaqo kwamanje, ukusetshenziswa kwezinto ezingavuthiwe zebanga likakhonkolo we-asphalt kuvamile, futhi kuzosetshenziswa imininingwane ehlukene. Ukhonkolo we-asphalt, ngakho-ke lapho isitshalo sokuxuba i-asphalt sicutshungulwa, izinto zokusetshenziswa zidinga ukulinganisa ngokuhambisana nemithethonqubo efanele, ukuze kuhlangatshezwane nezidingo zangempela zokwakha.
Ukhonkolo we-asphalt obekwe phansi ungahlukaniswa ngemibala ehlukene ebusweni. Lokhu futhi kuwumphumela wokhonkolo we-asphalt ngemva kokucubungula. Ngakho-ke, isitshalo se-asphalt sinezidingo zobuchwepheshe eziqinile futhi ububanzi bokusetshenziswa kwaso bubanzi. , okuhlanganisa ukugandaywa kwemigwaqo esheshayo, imigwaqo esezingeni, imigwaqo kamasipala, izikhumulo zezindiza, namachweba.
Isitshalo sokuxuba i-asphalt sihlanganisa umshini omkhulu kanye nemishini yokusiza. Ngesikhathi sokusetshenziswa, iqeda imisebenzi yesistimu eyinhloko njengokulinganisa, ukuhlinzeka, nokuxuba. Ngesikhathi sokusebenza kwesethi yonke yemishini yemishini, iqeda ngempumelelo ukukhiqizwa nokucubungula ukhonkolo we-asphalt, ukuhlinzeka ngengqalasizinda inikeza izindinganiso eziphakeme zezinto zokusetshenziswa, ngakho izitshalo zokuxuba i-asphalt zibalulekile ekukhiqizeni.
Isitshalo sokuxuba i-asphalt sisho isethi ephelele yemishini esetshenziselwa ukukhiqizwa ngobuningi bokhonkolo we-asphalt. Kuhlanganisa izingxenye ezifana nomshini wokugreda, isikrini esidlidlizayo, isiphakeli sebhande, isidluliseli esiyimpuphu, ilifti kanye ne-plug valve. I-valve yepulaki iyilungu elivalayo noma i-valve ejikelezayo emise okwe-plunger. Ngesikhathi sokusetshenziswa, idinga ukujikeleziswa ngamadigri angamashumi ayisishiyagalolunye ukwenza ukuvuleka kwephaseji kwepulaki ye-valve kufane naleyo esemzimbeni wevalvu. Ingabuye ihlukaniswe. ukuyenza ivuleke noma ivale. Uma isetshenziswa ezitshalweni zokuxuba i-asphalt, i-valve yepulaki ngokuvamile isesimweni se-cylinder noma i-cone.
Indima ye-valve ejikelezayo esitshalweni sokuxuba i-asphalt ukwenza ukwakheka kwemishini kube lula. Ngokuyinhloko isetshenziselwa ukusika noma ukuxhuma i-medium, futhi ingasetshenziswa njengendlela yokuguqula. Ukusebenza kwe-valve ejikelezayo esitshalweni sokuxuba i-asphalt kuyashesha futhi kulula. Ngisho noma isetshenziswa kaningi, ngeke kube nezinkinga ezinkulu. Yiqiniso, i-valve ye-rotary nayo inezinye izici eziningi. Ukwakheka kwayo kulula futhi kulula ukuyinakekela.
