Okokuqala, sidinga ukuhlaziya izimbangela eziyinhloko zokuchichima ezitshalweni zokuxuba i-asphalt:
1. Hlanganisa esiseleni esibandayo. Ngokuvamile kunezisele ezibandayo ezinhlanu noma ezine, ngayinye enezinhlayiya ezinobukhulu obuthile. Uma izinto ezibandayo zokucaciswa okuhlukile zixutshwe noma zifakwe ngephutha ngesikhathi sokuphakelwa, kuzodala ukushoda kwezinhlayiya zencazelo ethile phakathi nenkathi ethile yesikhathi, kanye nokuchichima kwezinhlayiya zesinye isicaciso, esingacekela phansi kalula ibhalansi yokudla phakathi. izisele ezishisayo nezibandayo.

2. Ukwakheka kwezinhlayiya zezinto ezingavuthiwe zokucaciswa okufanayo kunokuhlukahluka okukhulu. Njengoba kunezindawo ezimbalwa zamatshe amakhulu emakethe, ukucaciswa kwetshe elihlukile kuyadingeka endaweni yomgwaqo, futhi izingqimba zamatshe nezikrini ezisetshenziswa enkwalini ngayinye zinamamodeli ahlukene kanye nokucaciswa kwawo. Igravel enokucaciswa okufanayo kwegama okuthengwe ezindaweni ezihlukene zamatshe izoba Ukuhlukahluka kokwakheka kwezinhlayiyana kwenza kube nzima ngesitshalo sokuxuba ukulawula ibhalansi yokuphakelayo phakathi nenqubo yokuhlanganisa, okuholela emalini enqwabelene noma ekushoda kwezinto namatshe okucaciswa okuthile.

3. Ukukhethwa kwesikrini somgqomo oshisayo. Ngokwethiyori, uma ukuhlukaniswa komgqomo wezinto ezishisayo kuzinzile, kungakhathaliseki ukuthi zingaki izimbobo zesisefo ezakhiwe, ngeke kuthinte ukuhlukaniswa kwengxube. Kodwa-ke, ukuhlolwa kwe-silo eshisayo yesitshalo sokuxuba kunezici zokunciphisa usayizi wezinhlayiyana nokungakhuli, ngakho izinhlayiya zobukhulu obuthile zingase zixutshwe nezinhlayiya ezincane kunobukhulu bazo. Inani lalokhu okuqukethwe livame ukuba nomthelela omkhulu ekukhethweni kwesikrini kwesitshalo sokuxuba nokuthi siyachichima yini. Uma ijika lengxube libushelelezi futhi indawo yesikrini ikhethwe kahle, izinto eziqediwe ezikhiqizwa isitshalo sokuxuba zingaqinisekisa ukuthi ukuhlukaniswa akuchichimeki. Uma kungenjalo, lesi simo esichichimayo asinakugwenywa futhi singase sibe sibi kakhulu, sibangele udoti omkhulu wezinto ezibonakalayo kanye nokulahlekelwa kwezomnotho.

Ngemuva kokuchichima kwesitshalo sokuxuba i-asphalt, imiphumela elandelayo izokwenzeka:

1. Ingxube ihlelwe kahle. Kungabonakala enqubweni yokukala engenhla ukuthi lapho isisele esishisayo sichichima esilinganisweni esihle noma isamba esikhulu, isamba esihle sizokalwa ngenani elinqunywe kusengaphambili noma seqe ububanzi benani, kuyilapho isamba esikhulu sizokalwa ngokunqunywa kusengaphambili. inani. izovalwa, okuholela esinxephezelweni esinganele, okuholela ekuncipheni kokuhlolwa okuphelele noma okuyingxenye kwayo yonke ingxube. Uma sithatha izisele ezishisayo ezingu-4 njengesibonelo, ububanzi bokuhlola obungu-1#, 2#, 3#, kanye no-4# wezisele ezishisayo ngu-0~3mm, 3~6mm, 6~11.2~30mm, kanye no-11.2~30mm ngokulandelana. Uma isisele 3# sichichima, isisele 4# nokunye. Ngokufanayo, lapho indawo yokugcina impahla engu-1# ichichima, indawo yokugcina 2# iyachichima, njll., inani lesinxephezelo sempahla endizayo engu-1# lizodlula inani elibekiwe, futhi indawo yokugcina impahla engu-2# ngeke ifinyelele umthamo wokukala ngenxa yenani lesinxephezelo esinganele. . Inani elibekiwe, ukugreda sekukonke kuhle; lapho 2# inqolobane igcwala, indawo yokugcina 3# noma 4# indawo yokugcina impahla igcwala, izoba wugqinsi ngo-3~6mm futhi ibe ngu-6~30mm izacile.

2. Ingxube engahluziwe. Izingxube ezimahhadlahhadla zibangelwa izinhlayiya zesisefo ezinkulu ezisinda kakhulu noma izinhlayiya ezincane zesisefo zilula kakhulu. Thatha isikrini sesitshalo sokuxuba njengesibonelo: uma izindawo zokugcina impahla 1#, 2#, 3#, kanye no-4# zichichima, ezinye izindawo zokugcina impahla zizokala ngokunembile. Kungakhathaliseki ukuthi noma iyiphi indawo yokugcina impahla eyodwa, ezimbili noma ezintathu 1#, 2#, kanye no-3# ziyehluleka ukukala inani elimisiwe, izinga elilandelayo lezinhlayiya ezimahhadla kumele ligcwaliswe, okuzokwenza nakanjani kuholele ezintweni ezinkulu, Izinto ezincane nezixube ezimbalwa.

3. Kukhona ukuchezuka okukhulu ekuhlukaniseni izinhlayiya engxubeni. Ukuchichima esakhiweni sokuxubana kubangelwa ikakhulukazi ukukala okunganele kwezinga elithile lezinto eziyimbudumbudu emgqonyeni wezinto ezishisayo, okuholela ekweqiseni kwamanani ahlobene anele weleveli eyodwa noma ngaphezulu yezinto eziwumbudumbudu, okuholela ekuchichimeni. Isilinganiso semiksi yokukhiqiza sitholakala ngokuhlolwa kwe-silo eshisayo nokuxuba isivivinyo. Ngokuvamile, ngemva kokunqunywa kwembobo yesisefo ye-silo eshisayo, ukuhlukaniswa kwengxube ngeke kushintshe ngokuphawulekayo embonweni. Okungenani i-throughput eduze nembobo yesisefo ye-silo eshisayo kufanele ihlale izinzile. Ngaphandle kwalapho kunochungechunge lwemigqomo noma isikrini esiphukile kubhini oshisayo, kuzoba khona ukuchezuka okukhulu ebangeni lokuxutshwa kwama-granules. Kodwa-ke, ekusebenzeni kokwakha, kwatholakala ukuthi ukuhlukaniswa kwengxube kwakungazinzile ngemva kokukhetha izimbobo zesikrini.

Indlela yokulawula inani lokusabalalisa ingenye yezinkinga ezibalulekile okudingeka zixazululwe ngesikhathi sokuxuba ingxube ye-asphalt. Kufanele igwenywe ezicini ezilandelayo:

1. Imithombo ezinzile yezinto zokwakha. Umbhali uyaqaphela kusukela eminyakeni eminingi yokuzijwayeza ukukhiqiza ukuthi ukuzinza komthombo wezinto ezibonakalayo kuyisihluthulelo sokulawula ukuchichima. Itshe elilinganiselwe elingaqinisiwe liphumela ekushodeni noma ekudluleleni kwenani elithile leqoqo esitshalweni sokuxuba. Kuphela lapho umthombo wezinto ezibonakalayo uzinzile, isitshalo sokuxuba singalawula ngokuzinzile ukuhleleka kwengxube. Khona-ke, ngenkathi uqinisekisa ukuhlukaniswa, izinga lokugeleza kwesitshalo sokuxuba lingalungiswa ukuze kulinganiswe ukunikezwa kwezinto ezibandayo kanye nokunikezwa kwezinto ezishisayo ngesikhathi esifushane. isidingo. Uma kungenjalo, umthombo wokuphakelayo ngeke uzinze futhi ngeke kwenzeke ukugcina ibhalansi ethile yokuphakelayo isikhathi eside. Kuthatha isikhathi sokulungiswa ukusuka kubhalansi yokuphakelayo kuya kwesinye, futhi ibhalansi yokuphakelayo ayikwazi ukufinyelelwa ngesikhathi esifushane, okuholela ekuchichimeni. Ngakho-ke, ukulawula ukuchithwa, ukuzinza kwemithombo yezinto ezibonakalayo kuyisihluthulelo.

2. Ukukhetha okunengqondo kwesikrini se-silo esishisayo. Izimiso ezimbili kufanele zilandelwe ekuhlolweni: ① Qinisekisa ukuhlukaniswa kwengxube; (2) Qinisekisa ukuthi ukuchichima kwesitshalo sokuxuba kuncane ngangokunokwenzeka.

Ukuze kuqinisekiswe ukuhlukaniswa kwengxube, ukukhethwa kwesikrini kufanele kusondele kakhulu kusayizi wemeshi olawulwa i-gradation, njengo-4.75mm, 2.36mm, 0.075mm, 9.5mm, 13.2mm, njll. Ngokucabangela ukuthi isikrini sesikrini sesitshalo sokuxuba sinokuthambekela okuthile, usayizi wezimbobo zesikrini kufanele ukhuliswe ngokulinganayo.

Ukuchichima kwezitshalo zokuxuba bekulokhu kuyinkinga enzima ukuthi amayunithi wokwakha ayixazulule. Uma kuvuza kwenzeka, kuba nzima ukukulawula ngempumelelo. Ngakho-ke, ukuze kuqinisekiswe ukuthi kukhona ukuchichima okuncane ngangokunokwenzeka esitshalweni sokuxuba, kubalulekile ukufanisa umthamo wezinto ezibonakalayo we-hot bunker ngayinye namandla ayo okukhipha. Ngemva kokuba ijika lokugreda lesilinganiso senhlanganisela eqondiwe selinqunyiwe elabhorethri, ukukhethwa kwesikrini sesitshalo sokuxuba kufanele kusekelwe ejikeni lokugreda ukulinganisa ukugeleza kwempahla ebandayo kanye nesidingo sezinto ezishisayo zesitshalo sokuxuba. Uma izinga elithile lezinto eziwumbudumbudu lishoda, ububanzi bosayizi wesikrini saso kufanele bunwetshwe ngangokunokwenzeka ukuze kuqinisekiswe isidingo sezinto ezishisayo ezixutshiwe. Indlela eqondile imi kanje: Hlukanisa izigaba ezihlukene ejikeni lokuhlanganisa ingxube → Hlola ukuphuma kwezinto eziyimbudumbudu → Thola usayizi wemeshi ngokuya ngokuphuma kwawo → Yenza izilinganiso zomgqomo ngamunye oshisayo zilingane ngangokunokwenzeka → Nciphisa umthelela wezinto ezimpukane isinxephezelo ngokuthweswa iziqu Umthelela. Phakathi nenqubo yokubeka, zama ukukala izinga ngalinye lezinto zokwakha kuze kube sekugcineni. Ukuvalwa komnyango we-warehouse, kuncane isinxephezelo sezinto ezindizayo; noma inqolobane inezicabha ezimbili, owodwa omkhulu nomunye omncane, futhi ziyavulwa lapho ukukala kuqala. Noma yomibili iminyango ivulwa ngesikhathi esifanayo, futhi kuvulwa umnyango omncane kuphela ekupheleni kokukala ukuze kuncishiswe umthelela wesinxephezelo sezinto endizayo ekugredini ekupheleni kwesisindo.

3. Qinisa isiqondiso sokuhlola. Ilabhorethri kufanele ikhulise imvamisa yokuhlolwa kwezinto zokusetshenziswa ngokusekelwe enanini lezinto zokusetshenziswa ezingena esizeni kanye nezinguquko ezintweni ezingavuthiwe, lenze amajika agelezayo ezisele ezibandayo ngezikhathi ezithile, futhi yondle idatha ehlukahlukene ibuyisele esitshalweni sokuxuba ngesikhathi esifanele. indlela yokuqondisa ukukhiqizwa ngokunembile nangesikhathi esifanele, nokugcina izimo ezishisayo nezibandayo Ibhalansi yokuphakelayo okuhlobene kwezinto.

4. Ukwenziwa ngcono kwemishini yokuxuba ingxube ye-asphalt. (1) Misa amabhakede aphuphumayo amaningi esitsha sokuxuba, futhi usethe ibhakede elichichimayo lomgqomo ngamunye wezinto ezishisayo ukuze uvimbele ukuchichima ekuxubeni futhi kwenze kube nzima ukuphinda usetshenziswe; (2) Khulisa inani lesinxephezelo sempahla endizayo kuphaneli yokulawula yemishini yokuxuba Ngesibonisi nesisetshenziswa sokulungisa iphutha, imboni yokuhlanganisa ingalungisa inani lesinxephezelo sempahla endizayo kungakhathaliseki ukuthi iyachichima noma cha, ukuze ingxube ikwazi ukunakekela. ukuhleleka okuzinzile ngaphakathi komkhawulo.
