Ukuvalwa kwe-slurry kwaqala eJalimane futhi kunomlando weminyaka engaphezu kwengama-90. Ama-slurry seal anezinhlobonhlobo zezinhlelo zokusebenza futhi angasetshenziselwa ukulungisa umgwaqo omkhulu. Ngenxa yokuthi inezinzuzo zokonga amandla, ukunciphisa ukungcoliswa kwemvelo kanye nokwelula inkathi yokwakha, ithandwa kakhulu ochwepheshe bomgwaqo omkhulu kanye nabasebenzi bokulungisa. Isendlalelo sokuvalwa kwe-slurry senziwe ngama-chips amatshe asezingeni elifanele noma isihlabathi, izigcwalisi (usimende, umcako, umlotha wempukane, impushana yetshe, njll.), i-asphalt e-emulsified, izingxube zangaphandle namanzi, ezixutshwa zibe yi-slurry ngengxenye ethile bese zisakazwa A. isakhiwo esigandayiwe esisebenza njengophawu ngemva kokugandaywa, ukuqina nokwakhiwa. Ngenxa yokuthi ukungaguquguquki kwale ngxube yodaka kuncane futhi umumo ufana nodaka, ukujiya kokugandaya kuvame ukuba phakathi kuka-3-10mm, futhi kudlala indima enkulu yokuvimbela amanzi noma ukuthuthukisa kanye nokubuyisela umsebenzi wokugandaya. Ngokuthuthuka okusheshayo kwe-asphalt eyenziwe nge-polymer-modified emulsified kanye nokuthuthukiswa kobuchwepheshe bokwakha, i-polymer-modified emulsified asphalt slurry seal seal ibonakala.
I-slurry seal inemisebenzi elandelayo:
1. Ukuvimbela amanzi
Usayizi wezinhlayiyana ezihlanganisiwe zengxube ye-slurry muhle uma kuqhathaniswa futhi unokuhlelwa okuthile. Ingxube ye-asphalt slurry emulsified yenziwa ngemuva kokuthi umgwaqo ugandaywe. Ingakwazi ukunamathela ngokuqinile endaweni yomgwaqo ukuze yakhe ungqimba olungaphezulu oluminyene, olungavimbela imvula neqhwa ekungeneni kungqimba oluyisisekelo futhi kugcinwe ukuzinza kwesendlalelo sesisekelo nesisekelo senhlabathi:
2. Umphumela wokulwa nokushelela
Njengoba ukujiya kwe-emulsified asphalt slurry ingxube mncane, futhi izinto ezimahhadla ekudidiyelweni kwayo zisakazwa ngokulinganayo, futhi nenani letiyela lifanelekile, isenzakalo sokukhukhula kwamafutha emgwaqeni ngeke kwenzeke. Indawo yomgwaqo inendawo enhle emagebhugebhu. I-coefficient ye-friction ikhuphuke kakhulu, futhi ukusebenza kwe-anti-skid kuthuthukiswa kakhulu.
3. Ukumelana nokugqoka
I-Cationic emulsified asphalt inokunamathela okuhle kuzo zombili izinto zamaminerali ane-acidic kanye ne-alkaline. Ngakho-ke, ingxube ye-slurry ingenziwa ngezinto ezisezingeni eliphezulu zamaminerali okunzima ukugqoka nokugaya, ngakho-ke ingathola ukumelana nokugqoka okuhle futhi yandise impilo yesevisi yomgwaqo.
4. umphumela wokugcwalisa
Ingxube ye-asphalt slurry e-emulsified iqukethe amanzi amaningi, futhi ngemva kokuxuba, isesimweni se-slurry futhi ine-fluidity enhle. Le slurry inomphumela wokugcwalisa nokulinganisa. Ingamisa imifantu emincane endaweni yomgwaqo kanye nendawo egandayiwe engalingani ebangelwa ukuxega nokuwa endaweni yomgwaqo. I-slurry ingasetshenziselwa ukuvala imifantu futhi igcwalise imigodi engashoni ukuze kuthuthukiswe ubushelelezi bomgwaqo.
Izinzuzo ze-slurry seal:
1. Inokumelana nokugqoka okungcono, ukusebenza okungangeni manzi, nokunamathela okuqinile kungqimba olungaphansi;
2. Inganweba isikhathi sokuphila kwemigwaqo futhi yehlise izindleko eziphelele zokuyilungisa;
3. Isivinini sokwakha siyashesha futhi sinomthelela omncane kuthrafikhi;
4. Sebenza ngezinga lokushisa elijwayelekile, elihlanzekile futhi elinobungani nemvelo.
Ubuchwepheshe obubalulekile bokwakhiwa kokuvalwa kwe-slurry:
1. Izinto ezisetshenziswayo zihlangabezana nezidingo zobuchwepheshe. I-aggregate inzima, i-gradation inengqondo, uhlobo lwe-emulsifier lufanelekile, kanye nokuvumelana kwe-slurry kumaphakathi.
2. Umshini wokuvala uphawu unemishini ethuthukisiwe nokusebenza okuzinzile.
3. Umgwaqo omdala udinga ukuthi amandla awo wonke omgwaqo omdala ahlangabezane nezidingo. Izindawo ezinamandla anganele kumele ziqiniswe. Imigodi nemifantu emikhulu kufanele kumbiwe futhi kulungiswe. Amabhele namabhodi okugeza kumele kugaywe. Imifantu emikhulu kuno-3 mm kufanele igcwaliswe kusenesikhathi. Imigwaqo kufanele igezwe.
4. Ukuphathwa kwethrafikhi. Nciphisa isiminyaminya ukuze uvimbele izimoto ukuthi zingashayeli ocingweni olunodaka ngaphambi kokuba luqine.
