Ukuvala inkungu kuyindlela yokulungisa umgwaqo enezinhlelo eziningi ezahlukene. Isetshenziswa kakhulu emigwaqweni enokukhanya kuya kokumaphakathi kokulahlekelwa kwezinhlawulo noma okokusebenza okuxekethile. Isibonelo, lapho umgwaqo we-asphalt ukhululekile, ungqimba lwe-fog seal lungaxazulula inkinga; njengendawo eminyene yengxube yetiyela endaweni ephawulwe ngokuguga, ingaphezulu lesendlalelo se-gravel seal, ingaphezulu lengxube ye-asphalt evulekile, njll. Ibhekisela kakhulu eqinisweni lokuthi umgwaqo usuqalile ukukhombisa ukuqhekeka okuncane kokukhathala. kanye nokulahlekelwa okuphelele, kanye nokungena kwamanzi kwawo kwenyukile. Amanzi ahamba ngetiyela azongena engxubeni yetiyela ngemifantu noma ngomonakalo ophelele, abangele imifantu, imifantu, kanye nemigodi kanye nezinye izimo zomgwaqo lapho isakhiwo somgwaqo sisebenza kahle.
Umshini wokulungisa ungqimba lwe-fog seal: Imigwaqo eminingi yetiyela iguga ngokushesha eminyakeni yokuqala engu-2-4 yokusetshenziswa, okubangela ukuthi cishe i-1CM yetiyela emgwaqeni ibe brittle, okubangela ukuqhekeka kwangaphambi kwesikhathi, ukuxega kanye nomunye umonakalo endaweni yomgwaqo, namanzi akuqala. umonakalo ebusweni bomgwaqo. Izifo, ngakho-ke eminyakeni emi-2 kuye kwemine ngemuva kokuvulwa kwe-asphalt kumgwaqo isikhathi sokugcina ungqimba lophawu lwenkungu. Kufanele kunqunywe ngokuqondile ngokusekelwe ophenyweni lwezifo ezivamile zesakhiwo kanye nokusebenza kwe-pavement, inkomba yesimo se-pavement PCI, inkomba ye-international flatness IRI, ukujula kwesakhiwo, izimo zokuguga nezinye izici.
Umsebenzi wesendlalelo sokuvala inkungu:
(1) Umphumela ongangeni manzi, onganciphisa ngempumelelo umonakalo wamanzi phezu komgwaqo;
(2) Impahla yophawu lwenkungu inokungeneka okuhle futhi ingagcwalisa imifantu emihle kanye nezikhala ezingaphezulu endaweni yomgwaqo;
(3) Ngemva kokwakhiwa kongqimba lwenkungu yophawu, amandla okubopha phakathi kwamaqoqo ongqimba olungaphezulu kwetiyela angathuthukiswa, asebenze njengesivuseleli setiyela futhi avikele indawo egandayiwe yetiyela ene-oxidized;
(4) Ukwakhiwa kongqimba lwenkungu kungenza umgwaqo ube mnyama, kukhuphule umehluko wombala womgwaqo, futhi kwandise ukunethezeka kokubukwa komshayeli;
(5) Philisa ngokuzenzakalelayo imifantu engaphansi kuka-0.3MM;
(6) Izindleko zokwakha ziphansi futhi impilo yesevisi yomgwaqo inganwetshwa.
Izindlela zokwakha nezinyathelo zokuphepha:
(1) Iloli elikhethekile lokufutha noma ithuluzi lokufafaza elikhethekile longqimba lokuvala inkungu kufanele kusetshenziselwe ukufafaza ungqimba lokuvala inkungu ngokwezinga lokufafaza elimisiwe.
(2) Amaphethelo okufafaza ezindaweni zokuqala nezokugcina kufanele kuqinisekiswe ukuthi zihlanzekile, futhi uwoyela ozwakalayo kufanele ugandaywe kusengaphambili lapho uqala khona nalapho uphela khona.
(3) Uma ukusabalala okunemigqa noma ukuvuza kwempahla kwenzeka, ukwakhiwa kufanele kumiswe ngokushesha ukuze kuhlolwe.
(4) Isikhathi sokuphulukisa songqimba lwenkungu kufanele sinqunywe ngokuvumelana nohlobo lwempahla kanye nezimo zezulu, futhi singavulelwa ukuhamba kwezimoto kuphela ngemva kokuba somile futhi senziwe.
