Ndeipi nzira yekugadzira ye block bitumen inonyungudika michina? Chii chinonzi metering parameters?
Mushure mekunge bhitumini inonyunguditsa mudziyo yaita mita uye yagadziriswa, inoburutswa pabhandi rekutakura rinotenderera kure. Iyo block bhitumini inonyungudutsa midziyo inotumirwa kune yakarereka bhandi conveyor nebhandi rekutakura, uye yakarerekera bhandi conveyor inotakurwa kune yakamirira hopper mukati memusanganisi kumirira mirairo. Panguva imwecheteyo, kongiri nedota renhunzi zvinotakurwa nescrew conveyor kune yavo metering uye calibration hoppers yekuyera uye calibration. Zvigadzirwa zvekudzikisa mvura nemvura zvinopatsanurwa nemapombi emvura ecentrifugal uye zvigadzirwa zvinoderedza mvura. Iyo kongiri inonyudzwa mukongiri uye inomisikidzwa uye yakagadziriswa mune yakaenzana metering uye calibration hoppers.
Mushure mekuita mita uye kuenzanisa kwezvinhu zvakasiyana siyana zvebitumen kunyunguduka michina yapera, iyo control system inoburitsa mirairo yekuiisa zvishoma nezvishoma mumusanganisi wekusanganisa. Mushure mekunge kusanganiswa kwapera, gonhi rekurodha remusanganisi rinovhurwa, uye simende kongiri inoburutswa mumusanganisi kuburikidza nebhini rekurasira, yobva yapinda mune inotevera yekushanda cycle system.
Iyo block bitumen inonyungudutsa midziyo inoshandisa tekinoroji yekudzora majoini. Iyo inoyera uye inoratidza iwo ekutanga ma parameter eiyo block bitumen kunyungudutsa midziyo munguva chaiyo kuburikidza nemasensa, masisitimu ekugadzirisa masisitimu, maratidziro epaneru, nezvimwe, uye inodzora zvigadzirwa zvemagetsi kudzora ese ma mechanika emidziyo ye block bitumen inonyunguduka. Zvinoenderana nekushandiswa kwakasiyana kwekugadzirisa simende kongiri, inogona kukamurwa kuita chigadzirwa block bitumen kunyungudutsa midziyo uye yekuvaka purojekiti block bhitumini inonyungudutsa michina. Zviteshi zvekusanganisa zvekutengesa zvinonyanya kushandiswa kugadzira uye kutengesa simende kongiri, nepo kuvaka purojekiti yekusanganisa zviteshi zvinowanzo gadzira simende kongiri kubva kutanga. Zvechokwadi, nzira dzekudya dzakananga dzezviviri zvakasiyanawo. Naizvozvo, pakusarudza chiteshi chekusanganisa, zvinodikanwa kusarudza zvinoenderana nezvinodiwa zve block bitumen kunyungudutsa michina.
Mukugadzira uye kugadzirisa kwechivharo asphalt kunyungudutsa michina uchishandisa simende yakagadzikana ivhu yekusanganisa chiteshi michina, kuitira kuti isangane nezvinodiwa zvekuvaka, izvo zvinodiwa zvekusanganisa zvinhu uye reshiyo yemwaka zvese zvakaomarara. Iyo block asphalt yekunyungudutsa midziyo yakanangana nezvimwe zvinoenderana nechiyero chemwaka muindasitiri yesamende yakagadzikana yevhu yekusanganisa michina indasitiri. Iyo yakakura particle size yekugovera ye coarse aggregate mu block asphalt yekunyungudutsa midziyo haifanire kudarika 30mm.
Vhaka bhitumini inonyunguditsa midziyo inogona kubvumira dombo shoma repamusoro-giredhi rakawandisa dombo kuti riwedzerwe, asi mugove waro haufanire kudarika 2%. Coarse aggregate inofanira kutorwa kuchengetedza dhaka musanganiswa reshiyo, uye diki diki saizi yekugovera chikamu hachifanirwe kudarika 10%. Mugove webwe rakanaka maererano ne 0.3 round hole sieve haisi pasi pe15%. Mvura-simende reshiyo yekongiri mu block asphalt kunyungudutsa midziyo inodzorwa mukati meiyo 0.4-0.6, kudonha kwekongiri kuri 14-16cm, mvura-simende reshiyo yekongiri inofanira kunge iri 38% ~ 45%, uye pasi pemvura kongiri inofanirwa. kuitwa mukati maawa maviri mushure mekusanganiswa kwekongiri. Kongiri ine yakawandisa kudonha kuyerwa kukanganisa mu block bitumen kunyunguduka mudziyo haigone kupinda muhopi, uye inorambidzwa zvachose kuwedzera mvura kune hopper.
