Okokuqala, kufuneka sihlalutye izizathu eziphambili zokuphuphuma kwezityalo zokuxuba i-asphalt:
1. Xuba kwisisele esibandayo. Ngokuqhelekileyo kukho iisilo ezintlanu okanye ezine ezibandayo, nganye kuzo inamasuntswana obungakanani obuthile. Ukuba izinto ezibandayo zenkcazo ezahlukeneyo zixutywe okanye zifakwe ngempazamo ngexesha lenkqubo yokutya, oko kuya kubangela ukunqongophala kwamasuntswana enkcazo ethile phakathi kwexesha elithile, kunye nokuphuphuma kwamasuntswana enye inkcazo, enokuthi itshabalalise ngokulula ibhalansi yokutya phakathi. izisele ezishushu nezibandayo.

2. Ukuqulunqwa kweengqungquthela zezinto eziluhlaza zenkcazo efanayo kunokuhlukahluka okukhulu. Kuba kukho amasimi egrabile amakhulu kwimarike, imigangatho eyahlukeneyo yegrabile iyafuneka kumphezulu wendlela, kunye nezityuli zegrabile nezikrini ezisetyenziswa kwikwari nganye zinemizekelo eyahlukeneyo kunye neenkcukacha. Igrabile eneenkcukacha ezifanayo ezithengiweyo kwiindawo ezahlukeneyo zegrabile ziya Ukwahlukahlukana kokwakheka kwamasuntswana kwenza kube nzima kwisityalo sokuxuba ukulawula ibhalansi yokutya ngexesha lenkqubo yokuxuba, okukhokelela kwintsalela okanye ukunqongophala kwemathiriyeli kunye namatye eenkcukacha ezithile.

3. Ukukhethwa kwesikrini somgqomo oshushu. Ngokwethiyori, ukuba ukuhlelwa komgqomo wezinto ezishushu kuzinzile, kungakhathaliseki ukuba zingaphi izimbobo ze-sieve ezifakwe, aziyi kuchaphazela ukulinganisa umxube. Nangona kunjalo, ukuvavanywa kwe-silo eshushu yesityalo sokuxuba kuneempawu zokunciphisa ubungakanani be-particle kunye nokunganyuki, ngoko ke iinqununu zobukhulu obuthile zinokuxutywa kunye neencinci ezincinci kunobukhulu bazo. Isixa salo mxholo sisoloko sinempembelelo enkulu ekukhethweni kwesikrini sesityalo sokuxuba kunye nokuba siphuphuma. Ukuba ijika lomxube ligudileyo kwaye umgangatho wesikrini ukhethwe ngokufanelekileyo, izinto ezigqityiweyo eziveliswe sisityalo sokuxuba zinokuqinisekisa ukuba ukulinganisa akugqithisi. Kungenjalo, into ephuphumayo ayinakuthintelwa kwaye inokuba yingozi, ibangele inkunkuma enkulu kunye nelahleko yezoqoqosho.

Emva kokuba isityalo sokuxuba i-asphalt siphuphuma, iziphumo ezilandelayo ziya kwenzeka:

1. Umxube uhlelwe kakuhle. Inokubonwa kule nkqubo yokuweyisha ingentla ukuba xa isisele esishushu siphuphuma sibe sisidityana esicolekileyo okanye kwiaggregate enkulu, iaggregate ye fine aggregate iya kulinganiselwa kwisixa esimiselweyo okanye igqithe kuluhlu lwesixa, lo gama iaggregate enkulu iya kulinganiselwa kumlinganiselo osele ubekiwe. isixa. iya kuvalwa, nto leyo ekhokelela kwimbuyekezo eyanelanga, nto leyo ebangela ukuba kucutshungulwe ngokupheleleyo okanye ngokuyinxenye umxube wonke. Ukuthatha iisilo ezi-4 ezishushu njengomzekelo, uluhlu lokuhlola lwe-1#, 2#, 3#, kunye ne-4# iisilo ezishushu ngu-0~3mm, 3~6mm, 6~11.2~30mm, kunye ne-11.2~30mm ngokulandelelanayo. Xa isisele 3# siphuphuma, isisele 4# njl. njl Ngokufanayo, xa i-1 # isitora iphuphuma, i-2 # isitora iyaphuphuma, njl. njl., isixa-mali sembuyekezo ye-1 # yempahla ephaphazelayo ye-1 # iya kudlula isixa esimiselweyo, kwaye i-2 # indawo yokugcina impahla ayiyi kufikelela kumthamo wokulinganisa ngenxa yesixa sembuyekezo enganelanga. . Isixa esisetwayo, umgangatho uwonke ulungile; xa 2# ugcino ephuphuma, 3# indawo yokugcina okanye 4# indawo yokugcina impahla iya kuphuphuma, iya kuba yi-3 ~ 6mm ubukhulu kunye ne-6 ~ 30mm encinci.

2. Umxube okrwada. Imixube erhabaxa yenziwa kukuba amasuntswana esefa amakhulu abenzima kakhulu okanye amasuntswana esefo amancinci abe khaphukhaphu kakhulu. Thatha isikrini sesityalo sokuxuba njengomzekelo: xa iindawo zokugcina 1#, 2#, 3#, kunye ne-4# ziphuphuma, ezinye iindawo zokugcina ziya kukala ngokuchanekileyo. Kungakhathaliseki ukuba nayiphi na enye, ezimbini okanye ezintathu zokugcina 1 #, 2 #, kunye 3 # ziyasilela ukulinganisa ubungakanani obumiselweyo, inqanaba elilandelayo lamasuntswana arhabaxa kufuneka ligcwaliswe, nto leyo eya kukhokelela kwizinto ezinkulu, izixhobo ezincinci kunye nemixube.

3. Kukho ukutenxa okukhulu kwi-gradation of particles in the mix. Ukugqithisa kwisakhiwo sokuxuba kubangelwa ubukhulu becala ngenxa yokulinganisa okunganeleyo kwinqanaba elithile lezinto zegranular kwi-bin material eshushu, okubangelwa ukugqithisa okwaneleyo kwemilinganiselo eyaneleyo yomgangatho omnye okanye ngaphezulu kwezinto zegranular, okubangelwa ukuphuphuma. Umlinganiselo womxube wemveliso ufumaneka ngokuhlolwa kwe-silo eshushu kunye nokuxubana kwezilingo. Ngokuqhelekileyo, emva kokuba umngxuma we-sieve we-silo eshushu unqunywe, ukuhlelwa komxube akuyi kutshintsha kakhulu kwithiyori. Ubuncinci i-throughput kufuphi nomngxuma wesihluzo we-silo eshushu kufuneka ihlale izinzile. Ngaphandle kokuba kukho umtya wemigqomo okanye isikrini esaphukileyo kwi-bin eshushu, kuya kubakho ukutenxa okukhulu kwibakala lomxube we-granules. Nangona kunjalo, kumsebenzi wokwakha, kwafunyaniswa ukuba ukuhlelwa komxube kwakungazinzanga emva kokukhetha imingxuma yesikrini.

Indlela yokulawula isixa esisasazekayo yenye yezinto eziphambili ezifuna ukusonjululwa ngexesha lokuxuba umxube we-asphalt. Kufuneka ithintelwe kule miba ilandelayo:

1. Imithombo ezinzileyo yemathiriyeli. Umbhali uyaqonda ukusuka kwiminyaka emininzi yokusebenza kwemveliso ukuba ukuzinza komthombo wezinto eziphathekayo kuyisitshixo sokulawula ukuphuphuma. Igrabile engaqinisekanga ibangela ukunqongophala okanye ukugqithiswa kwebakala elithile leaggregate kwiplanti yokuxuba. Kuphela xa umthombo wezinto eziphathekayo uzinzile, isityalo sokuxuba sinokulawula ngokuzinzileyo ukulinganisa umxube. Emva koko, ngelixa uqinisekisa ukuhla, izinga lokuhamba kwesityalo sokuxuba sinokuhlengahlengiswa ukulungelelanisa ukunikezelwa kwezinto ezibandayo kunye nokunikezelwa kwezinto ezishushu ngexesha elifutshane. isidingo. Ngaphandle koko, umthombo wesondlo uya kungazinzi kwaye akunakwenzeka ukugcina ibhalansi ethile yokutya ixesha elide. Kuthatha ixesha lohlengahlengiso ukusuka kwelinye ibhalansi yokutya ukuya kwelinye, kwaye ibhalansi yokutya ayinakufikelelwa ngexesha elifutshane, okubangela ukuphuphuma. Ngoko ke, ukulawula ukuchithwa, ukuzinza kwemithombo yezinto eziphathekayo kubalulekile.

2. Ukukhetha okufanelekileyo kwesikrini se-silo eshushu. Imigaqo emibini kufuneka ilandelwe ekuhlolweni: ① Qinisekisa umgangatho womxube; (2) Qinisekisa ukuba ukuphuphuma kwesityalo sokuxuba kuncinci kangangoko.

Ukuze kuqinisekiswe ukuhla komxube, ukukhethwa kwesikrini kufuneka kube ngokusondeleyo kangangoko kunokwenzeka kwisayizi ye-mesh elawulwa yi-gradation, njenge-4.75mm, 2.36mm, 0.075mm, 9.5mm, 13.2mm, njl. ukuba umnatha wekhusi wesityalo sokuxuba unotyekelo oluthile, ubungakanani bemingxuma yesikrini kufuneka bonyuswe ngokulinganayo.

Ukugqithiswa kwezityalo zokuxuba kuye kwaba yingxaki enzima kwiiyunithi zokwakha ukusombulula. Nje ukuba kuvuze kuvuze, kuba nzima ukukulawula ngokufanelekileyo. Ngoko ke, ukwenzela ukuba kuqinisekiswe ukuba kukho ukuphuphuma okuncinci kunokwenzeka kwisityalo sokuxuba, kubalulekile ukufanisa umthamo wezinto eziphathekayo zebhankethi nganye eshushu kunye nomthamo wayo wokukhupha. Emva kokuba i-curve grading ratio ye-target mix ratio igqitywe kwilabhoratri, ukukhethwa kwesikrini sesityalo sokuxuba kufuneka kusekelwe kwi-curve yokulinganisa ukulinganisa ukuhamba kwezinto ezibandayo kunye nemfuno eshushu yezinto ezixutywayo. Ukuba ibakala elithile lezinto zegranular linqongophele, uluhlu lwesayizi yesikrini sayo kufuneka lwandiswe kangangoko kunokwenzeka ukuze kuqinisekiswe imfuno yezinto ezixubeneyo ezishushu. Indlela ethile yile ilandelayo: Yahlula amacandelo ahlukeneyo kumxube wegophe lokudityaniswa → Khupha isiphumo semathiriyeli yegranular → Khangela ubungakanani bemesh ngokokuphuma → Yenza umlinganiselo womgqomo ngamnye oshushu ulingane kangangoko → Nciphisa impembelelo yemathiriyeli yempukane. imbuyekezo kwi-gradation Impembelelo. Ngethuba lenkqubo yokumisela, zama ukulinganisa inqanaba ngalinye lezinto eziphathekayo ukuya ekupheleni. Incinci ingcango yendawo yokugcina impahla ivaliwe, incinci imbuyekezo yezinto ezibhabhayo; okanye indawo yokugcina impahla ineengcango ezimbini, enye enkulu nencinane, yaye ziyavulwa xa ukulinganisa kuqala. Okanye zombini iingcango zivulwa ngaxeshanye, kwaye kuphela ucango oluncinci luvulwa ekupheleni kokulinganisa ukunciphisa impembelelo yembuyekezo yezinto eziphaphazelayo ekuhleleni ekupheleni kokulinganisa.

3. Ukuqinisa isikhokelo sovavanyo. Ilabhoratri kufuneka yandise ukuphindaphindwa kovavanyo lwemathiriyeli ekrwada ngokusekwe kubungakanani bezinto eziluhlaza ezingena kwindawo kunye notshintsho kwizinto eziluhlaza, zenze iigophe ezijikelezayo zeesilo ezibandayo amaxesha ngamaxesha, kwaye zondle idatha eyahlukeneyo ibuyele kwisityalo sokuxuba ngexesha elifanelekileyo. indlela yokukhokela imveliso ngokuchanekileyo nangexesha, kunye nokugcina iimeko ezishushu nezibandayo ezikwi-Relative feed balance of materials.

4. Ukuphuculwa kwezixhobo zokuxuba umxube we-asphalt. (1) Misela ii-emele eziphuphumayo ezininzi zeplanti yokuxuba, kwaye ubeke i-emele ephuphumayo kumgqomo wezinto ezishushu ngamnye ukukhusela ukuphuphuma kokuxutywa kunye nokwenza kube nzima ukuphinda usetyenziswe; (2) Ukwandisa ubungakanani bembuyekezo yezinto ezibhabhayo kwiphaneli yokulawula yesityalo sokuxuba Ngomboniso kunye nesixhobo sokucoca, isityalo sokuxuba sinokulungelelanisa isixa sembuyekezo yezinto eziphaphazelayo kungakhathaliseki ukuba kuphuphuma okanye cha, ukwenzela ukuba umxube unokugcina. udidi oluzinzileyo phakathi komda.
