Yiziphi Izinhlobo Ezihlukene Zezitshalo Zokuxuba I-Asphalt?

Isingeniso Sezitshalo Zokuxuba I-Asphalt

Izitshalo zokuxuba i-asphalt ziyizinto ezibalulekile embonini yokwakha, zidlala indima ebalulekile ekukhiqizweni kwe-asphalt, into eyisisekelo yokwakha nokulungisa imigwaqo. Kodwa-ke, ngezinhlobonhlobo zezitshalo ezitholakalayo, kungaba nzima ukunquma ukuthi yiluphi uhlobo olufanelana nezidingo zakho ezithile. Kulesi sihloko, sizohlola izinhlobo ezahlukene zezitshalo zokuxuba i-asphalt, izici zazo, kanye nezimo lapho zisebenza kahle kakhulu khona.

Ukuqonda Izisekelo

Ngaphambi kokuhlola izinhlobo ezahlukene, kubalulekile ukuqonda umsebenzi oyisisekelo wesitshalo sokuxuba i-asphalt. Lezi zitshalo zihlanganisa i-aggregate (njengesihlabathi, amatshe ayigugu, namatshe), i-bitumen (i-bonding agent), nezinye izithasiselo ukukhiqiza i-asphalt, into esetshenziselwa ukugandaya imigwaqo, izindawo zokupaka, kanye nezinye izindawo. Ukusebenza kahle kanye nekhwalithi ye-asphalt kuncike kakhulu ohlotsheni lwesitshalo esisetshenziswayo.

1. Izitshalo Ezixubile Ze-Asphalt

Izitshalo ze-asphalt ezixutshwe ngamaqoqo zingenye yezinhlobo ezivame kakhulu zezitshalo zokuxuba i-asphalt. Njengoba igama lisho, lezi zitshalo zikhiqiza i-asphalt ngamaqoqo, kanti i-batch ngayinye iqukethe inani elithile le-aggregate kanye ne-bitumen. Le nqubo ivumela ukulawula okukhulu ikhwalithi yomkhiqizo wokugcina, okwenza izitshalo ze-batch mix zilungele amaphrojekthi amakhulu lapho ukuhambisana kubalulekile khona.

Enye yezinzuzo ezibalulekile zezitshalo ezixutshwe ngama-batch ukuguquguquka kwazo. Zingenziwa ngokwezifiso kalula ukuze zikhiqize izinhlobo ezahlukene ze-asphalt, zihambisane nezidingo ezahlukene zephrojekthi. Kodwa-ke, zivame ukuba nezindleko zokusebenza eziphakeme kanye nezikhathi zokukhiqiza ezinde uma kuqhathaniswa nezinye izinhlobo zezitshalo.

2. Izitshalo Ezixubile Ze-Asphalt Eziqhubekayo

Ngakolunye uhlangothi, izitshalo ze-asphalt ezixubile njalo zikhiqiza i-asphalt ngokugeleza okuqhubekayo. Ngokungafani nezitshalo ze-batch mix, izitshalo ze-continuous mix azikhiqizi i-asphalt ngamaqoqo ahlukene; kunalokho, zigcina ukugeleza okuqhubekayo kokukhiqiza. Lokhu kuzenza zisebenze kahle futhi zingabizi kakhulu kumaphrojekthi amakhulu, esikhathi eside.

Lezi zitshalo zilungele kakhulu amaphrojekthi adinga i-asphalt eningi, njengokwakhiwa komgwaqo omkhulu. Kodwa-ke, kungenzeka ukuthi aziyona inketho engcono kakhulu kumaphrojekthi amancane noma lawo adinga izinguquko ezivamile ohlotsheni lwe-asphalt.

3. Izitshalo Zokuxuba I-Asphalt Ezihambayo

Izitshalo zokuxuba i-asphalt ezihambayo zenzelwe ukuguquguquka nokuphatheka kalula. Lezi zitshalo zilungele amaphrojekthi adinga ukukhiqizwa kwe-asphalt ezindaweni ezikude noma kumaphrojekthi esikhashana lapho ukusetha isitshalo esihlala njalo kungenzeki khona. Izitshalo ezihambayo zincane, kulula ukuzithutha, futhi zingahlanganiswa futhi zihlukaniswe ngokushesha.

Enye yezinzuzo eziyinhloko zezitshalo zokuxuba i-asphalt ezihambayo yikhono lazo lokunciphisa izindleko zokuhamba. Ngokukhiqiza i-asphalt endaweni, osonkontileka bangagwema izindleko zokuthutha i-asphalt kusuka esitshalweni esikude ukuya endaweni yokwakha. Kodwa-ke, izitshalo ezihambayo zingase zibe namandla okukhiqiza aphansi uma kuqhathaniswa nezitshalo ezimile.

4. Izitshalo Ze-Asphalt Ezixutshwe Ngesigubhu

Izitshalo ze-asphalt ezixubene nezigubhu ziwuhlobo lwesitshalo esixubene esiqhubekayo esisebenzisa i-drum ukuhlanganisa i-aggregate ne-bitumen. Lezi zitshalo zaziwa ngokusebenza kwazo kahle kakhulu futhi zivame ukusetshenziselwa amaphrojekthi amakhulu. I-drum mixer iqinisekisa ukuthi i-aggregate ishiswa ngokulinganayo, okuholela kumkhiqizo we-asphalt ohambisanayo nosezingeni eliphezulu.

Izitshalo zokuxuba izigubhu zithandwa kakhulu ezindaweni ezinesimo sezulu esifudumele, njengoba zifaneleka kahle ukukhiqiza i-asphalt exubile eshisayo. Kodwa-ke, kungenzeka ukuthi aziyona inketho engcono kakhulu kumaphrojekthi adinga ukukhiqizwa kwe-asphalt exubile ebandayo.

5. Izitshalo ze-Asphalt eziphikisanayo

Izitshalo ze-asphalt ezisebenzisa i-counterflow ziyizinhlobo ezahlukene zezitshalo ezixuba i-drum ezisebenzisa i-counterflow drum ukuxuba. Kulezi zitshalo, i-aggregate kanye ne-bitumen kugeleza ngezindlela eziphambene ngaphakathi kwe-drum, okuvumela ukuxuba okuphumelelayo nokulawula kangcono umkhiqizo wokugcina.

Izitshalo ezisebenzisa i-counterflow zaziwa ngekhono lazo lokukhiqiza i-asphalt esezingeni eliphezulu enokukhishwa okuncane komoya, okwenza kube yindlela enobungani nemvelo. Kodwa-ke, zingaba nzima kakhulu ukuzisebenzisa nokuzinakekela uma kuqhathaniswa nezinye izinhlobo zezitshalo.

Isiphetho

Ekuphetheni, uhlobo lwesitshalo sokuxuba i-asphalt osikhethayo luzoncika ezidingweni ezithile zephrojekthi yakho. Kungakhathaliseki ukuthi udinga isitshalo sokuxuba i-batch ukuze sikwazi ukuguquguquka, isitshalo sokuxuba esiqhubekayo ukuze sisebenze kahle, noma isitshalo esihambayo ukuze sikwazi ukuthwala kalula, ukuqonda umehluko phakathi kwalezi zinhlobo zezitshalo kuzokusiza ukuthi wenze isinqumo esinolwazi. Ngokukhetha isitshalo sokuxuba i-asphalt esifanele izidingo zakho, ungaqinisekisa impumelelo kanye nobude bemisebenzi yakho yokwakha.
