Zisebenza Njani Izityalo Ze-Asphalt? Ingcaciso Enzulu
Ukuqonda Iziseko Zezityalo Ze-Asphalt
Ngaba wakha wazibuza ukuba izityalo ze-asphalt zisebenza njani? Ukuba ubandakanyeka kulwakhiwo, ekwakheni iindlela, okanye kubunjineli bokwakha, ukuqonda indlela izityalo ze-asphalt ezisebenza ngayo kubalulekile. Izityalo ze-asphalt zingumqolo wokwakhiwa kweendlela zanamhlanje, ukuvelisa izixhobo ezifunekayo ukugawula iindlela, iindlela ezinkulu, kunye neendawo zokupaka. Kodwa ezi zityalo zisebenza njani kanye kanye? Masiyihlalutye inyathelo ngenyathelo.
Yintoni isityalo seAsphalt?
Isityalo se-asphalt sisixhobo esenziwa yi-asphalt, umxube wezinto ezidityanisiweyo (njengesanti, ilitye eliqhekekileyo, kunye nelitye elityumkileyo) kunye ne-bitumen, olulwelo olunamathelayo, olumnyama, nolunamandla kakhulu oluvela kwi-petroleum. Lo mxube uyafudunyezwa kwaye udityaniswe ngokwemilinganiselo ethile ukwenza izinto ezigudileyo, ezihlala ixesha elide, neziguquguqukayo ezisetyenziselwa ukugquma iindlela.
Izinto ezibalulekileyo kwisityalo se-Asphalt
Ngaphambi kokuba ungene kwinkqubo, kubalulekile ukuqonda izinto ezibalulekileyo kwisityalo se-asphalt. Ezi ziquka:
- Iibhini eziDibeneyo : Ezi zikhongozeli zokugcina izinto ezigcina izinto eziluhlaza ezifana nesanti, ilitye eliqhekekileyo kunye namatye atyumkileyo.
- Idrama Yokomisa : Kulapho kufudunyezwa khona ii-aggregates ukususa umswakama nokuzilungiselela ukuxuba.
- Indlu yeengxowa okanye yokuqokelela uthuli : Le nkqubo ihluza uthuli kunye namasuntswana avela kwiigesi zokukhupha umoya ukuze ihlangabezane nemigaqo yokusingqongileyo.
- Inqaba Yokuxuba : Kulapho ke izinto ezishushu ezidityaniswe khona nebitumen nezinye izongezo ukuze kwenziwe umxube wokugqibela we-asphalt.
- IiSilo zokugcina : Ezi zigcina imveliso ye-asphalt egqityiweyo ide ilungele ukuthuthwa iye kwiindawo zokwakha.
Inkqubo Yokuvelisa I-Asphalt
Ukusebenza kwesityalo se-asphalt kungahlulwahlulwa ngokwamanqanaba aliqela:
1. Ukulungiselela Okupheleleyo
Inkqubo iqala ngokukhupha nokulungisa ii-aggregates. Ezi zinto zihlala zifunyanwa kwiingxobo okanye kwimigxobhozo yesanti, emva koko zityunyuzwe zize zihluzwe ngokobukhulu obufunekayo. Ii-aggregates zigcinwa kwiibhini ezahlukeneyo ukuqinisekisa ukuba zilungele inyathelo elilandelayo.
2. Ukomisa kunye nokuFudumeza
Emva koko ezi aggregates zifakwa kwidrama yokomisa, apho zifudunyezwa khona ukuya kumaqondo obushushu aphezulu (ngesiqhelo malunga ne-300°F) ukuze kususwe naluphi na umswakama. Eli nyathelo libalulekile kuba umswakama unokuphazamisana neempawu zokubopha zebhitumen.
3. Ukuxuba neBitumen
Xa ii-aggregates zomile kwaye zishushu, zidluliselwa kwi-mixing tower. Apha, i-bitumen yongezwa kumxube, kunye nezongezo ezifana nezizalisi, imicu, kunye neekhemikhali eziphucula ukusebenza kwe-asphalt. Lo mxube uphela udityaniswe kakuhle ukuqinisekisa ukuba uyafana.
4. Ulawulo loMgangatho
Emva kokuxuba, i-asphalt iyavavanywa ukuqinisekisa ukuba iyahlangabezana nemigangatho efunekayo. Oku kuquka ukujonga ukuhambelana, uxinano, kunye nokuqina. Ukuba ibhetshi ayihlangabezani neemfuno, kwenziwa uhlengahlengiso ngaphambi kokuba i-asphalt igcinwe kwii-silos.
5. Ugcino kunye nokuThuthwa
I-asphalt egqityiweyo igcinwa kwii-silos ezigqunyiweyo ukuze kugcinwe ubushushu bayo. Xa kufika ixesha lokuthutha i-asphalt ukuya kwindawo yokwakha, ilayishwa kwiilori ezigqunyiweyo ukuze zigcine izinto zishushu ngexesha lokuhamba.
Izinto eziqwalaselwayo kwiNdalo
Izityalo ze-asphalt zanamhlanje ziyilwe kucingwa ngokugcinwa kwendalo. Izityalo ezininzi ngoku zisebenzisa ubuchwepheshe obusebenzisa amandla kakuhle kunye neenkqubo zokunciphisa ukukhutshwa komoya. Umzekelo, ezinye izityalo zisebenzisa i-asphalt pavement ephinde yasetyenziswa (i-RAP) endaweni yezinto ezingabonakaliyo, ukunciphisa inkunkuma kunye nokugcina izixhobo zendalo. Ukongeza, iingxowa kunye nabaqokeleli bothuli baqinisekisa ukuba izinto ezincinci ziyancitshiswa, nto leyo enciphisa impembelelo yesityalo kwindalo.
Iintlobo eziqhelekileyo zezityalo zeAsphalt
Kukho iintlobo ezahlukeneyo zezityalo ze-asphalt, nganye yenzelwe ukuhlangabezana neemfuno ezithile:
- Izityalo zeBatch : Ezi zityalo zivelisa i-asphalt ngokwamaqela, nto leyo evumela ulawulo oluchanekileyo kumxube. Zilungele iiprojekthi ezinkulu.
- Izityalo zeDrum Mix : Ezi zityalo zivelisa i-asphalt rhoqo, nto leyo eyenza ukuba zisebenze ngakumbi kwimveliso enomthamo omkhulu.
- Izityalo Eziphathwayo : Ezi ziiyunithi ezincinci, ezihambayo ezinokufuduselwa kwiindawo ezahlukeneyo, nto leyo ezenza zibe zilungele iindawo zokwakha ezikude.
Isiphelo
Izityalo ze-asphalt zidlala indima ebalulekileyo ekwakheni nasekugcineni iziseko zophuhliso zanamhlanje. Ngokuqonda indlela ezisebenza ngayo ezi zityalo, unokuyiqonda indlela ezintsonkothileyo kunye nokuchaneka ngayo okubandakanyekayo ekuveliseni i-asphalt esemgangathweni ophezulu. Nokuba ungumakhi, unjineli, okanye unomdla nje kule nkqubo, ukwazi yonke into eyenzeka kwimveliso ye-asphalt kunokukunceda wenze izigqibo ezinolwazi kwiprojekthi yakho elandelayo. Nangona kunjalo, ukuba unemibuzo engaphezulu malunga nezityalo ze-asphalt, zive ukhululekile ukunxibelelana neengcali ukuze ufumane isikhokelo esithe vetshe.
