(1) Kudzora tembiricha yemusanganiswa:
Kupisa kwemusanganiswa ndeimwe yemaitiro ekufanirwa kuongororwa kwemusanganiswa. Kana tembiricha yakanyanyisa kana kuti yakaderera, ichava dongo uye haigone kushandiswa. Naizvozvo, maitiro ekudzora tembiricha ndeimwe yehunyanzvi hunyanzvi hunofanirwa kuve nevashandisi.
Zvinhu zvinokanganisa kupisa kwemusanganiswa zvinosanganisira kunaka kwemafuta. Kana hutano hwemafuta husina kunaka, iyo calorific value yakaderera, uye kupisa kusina kukwana, kuchaita kuti dombo rive risina kugadzikana, kutonhora kunenge kwakaderera, uye zvakasara zvinopisa zvicharamba zviri mumusanganiswa, zvichikanganisa zvakanyanya kunaka kwemusanganiswa. Kana iyo viscosity yemafuta yakanyanyisa, kusvibiswa kwemukati kwakakwirira, uye mvura yemvura yakakwirira. Ichakonzera matambudziko ekubatidza, kuvharika kwepombi, uye kutonga kwekushisa. Hunyoro hwezvinhu zvakabikwa chimwe chinhu chinokanganisa tembiricha. Iyo mbishi ine hunyoro hukuru uye haina kuenzana. Munguva yekugadzira, kupisa kwekupisa kwebwe kwakaoma kudzora. Uye zvakare, iyo tekinoroji mamiriro eiyo combustion system, kudzvanywa kwepombi yekupa mafuta, uye huwandu hwejekiseni remafuta zvese zvine chekuita nekupisa kwemusanganiswa. Kutadza kwakadai sekupfeka, kubuda kwemhepo, uye kuvharika kweiyo combustion system inodzivirira chikamu chimwe nechimwe kubva pakuchengeta kuita kwayo kwepakutanga, zvichikonzera kuderera kwehurongwa hwekudzvanywa, kusagadzika kwemafuta, kushomeka kweatomization combustion, uye zvakanyanya kukanganisa tembiricha inomutsa.
Nokudaro, vashandi vane ruzivo vanofanira kukwanisa kutonga zvakarurama kunaka kwemafuta, kuoma uye kunyorova kwezvinhu zvakasvibirira, uye mamiriro ekushanda kwegadziriro yekupisa. Tora matanho akakodzera nekukasika kana matambudziko aonekwa. Kunyangwe michina yemazuva ano yekusanganisa ine otomatiki tembiricha yekudzora tembiricha, tembiricha yekudzora ine lag nekuti inoda maitiro kubva pakuona tembiricha kusvika pakuwedzera nekubvisa marimi emoto kugadzirisa tembiricha. Kuti uve nechokwadi chekuti tembiricha yekusanganisa yekusanganisa chiteshi haiburitse tsvina, anoshanda anofanirwa kunyatso cherechedza shanduko yekushisa, kufanotaura mhedzisiro yekushanduka kwekushisa pachine nguva, uye nemaoko kuwedzera kana kuderedza murazvo kana kuwedzera kana kudzikisa huwandu hwekudya kudzora. kushanduka kwekushisa kuitira kuti mhinduro dzekuchinja Usapfuure huwandu hwakatarwa, nokudaro kuderedza kana kubvisa tsvina.
(2) Giredhi kutonga kwemusanganiswa:
Kukwidziridzwa kwemusanganiswa kunokanganisa zvakananga kushanda kwepavement. Kana iyo gradation yemusanganiswa isinganzwisisike, iyo nzira ichatambura kubva kune zvimwe zvirwere senge hombe kana diki void ratio, mvura permeability, rutting, nezvimwewo, izvo zvinoderedza hupenyu hwebasa repavement uye kukanganisa zvakanyanya kunaka kweprojekiti. Naizvozvo, iyo gradation kutonga kwemusanganiswa zvakare humwe hunyanzvi hunofanirwa kuve nemushandisi.
Zvinhu zvinokanganisa kukwenenzverwa kwemusanganiswa zvinosanganisira: shanduko mune yakasvibira particle size, shanduko mune yekusanganisa chiteshi chidzitiro, kuyerwa kukanganisa, nezvimwe.
Iyo particle size yezvinhu zvakasvibirira inokanganisa zvakananga gradation yemusanganiswa. Kana shanduko mune zvigadzirwa zvawanikwa, mushandisi anofanirwa kushandira pamwe nerabhoritari kugadzirisa muyero wemusanganiswa wekugadzira. Shanduko yechidzitiro chemidziyo inopisa muchiteshi chekusanganisa chinhu chakakosha chinokanganisa kukwidziridzwa kwemusanganiswa. Kana iyo skrini yakavharwa uye zvinhu zvinopisa zvikasatariswa zvakakwana, giredhi inozotetepa. Kana iyo skrini yakatyoka, ikakuvadzwa, yadeuka, kana kupfekwa kupfuura muganhu, ichaita kuti musanganiswa uwedzere kukora; iyo yekuyera kukanganisa kweiyo yekusanganisa chiteshi inobatawo zvakananga gradation. Kana kuyerwa kwekukanganisa kwakagadziriswa kwakakura zvakanyanya, chiyero chemusanganiswa wekugadzira chinotsauka zvakanyanya kubva pachinangwa chemusanganiswa reshiyo, zvichikanganisa zvakanyanya kunaka kwemusanganiswa. Kana kuyerwa kwekuyerwa kwakagadziriswa kudiki zvakanyanya, kuchawedzera kuyerwa nguva uye kukanganisa kubuda. Izvo zvakare zvinokonzeresa kuti kuyerwa kunowanzo kudarika muganho uye kukanganisa kushanda kwakajairwa kwechiteshi chekusanganisa.
Muchidimbu, mutyairi anofanirwa kunyatso tarisisa shanduko yezvigadzirwa, tarisa skrini nguva zhinji, kugadzirisa matambudziko panguva yakakodzera, uye kugadzirisa chiyero chekuyera kune yakanakisa mamiriro zvichienderana nehunhu hwechiteshi chekusanganisa uye zvimwe zvinhu. Nyatsofunga zvimwe zvinhu zvinokanganisa gradation kuti uve nechokwadi chekusanganiswa kweiyo jet mill musanganiswa.
(3) Kudzora kweiyo mafuta-dombo reshiyo yemusanganiswa:
Iyo asphalt musanganiswa weasphalt-dombo reshiyo inotarwa negradation yemaminerari zvinhu uye zviri mukati mehupfu. Ndiyo vimbiso yakakosha yesimba repavement uye kuita kwayo. Yakawandisa kana kushoma asphalt inokonzeresa zvirwere zvakasiyana panzira.
Naizvozvo, kunyatso kudzora huwandu hweasphalt chikamu chakakosha chekutonga kwekugadzira. Vashandi vanofanirwa kutarisisa kune zvinotevera zvinhu panguva yekugadzira:
Panguva yekushanda, edza kugadzirisa kukanganisa kweyero yeasphalt sediki sezvinobvira kuti uwane yakanakisa asphalt kuyerwa; huwandu hwehupfu hunowedzerawo chinhu chakakosha chinokanganisa asphalt-stone ratio, saka kuyerwa kwehupfu kunofanirawo kunyatsodzorwa; maererano neguruva rehuwandu hwehuwandu hwakanaka, ita zvigadziriso zvinonzwisisika Kuvhurwa kweiyo induced dhizaini fan inovimbisa kuti guruva remukati musanganiswa riri mukati meiyo dhizaini renji.
