Ngokuthuthuka okuqhubekayo kwezokuthutha komgwaqo omkhulu emhlabeni, indlela yokwenza i-asphalt pavement ingagcini nje ngokuqinisekisa ukusebenza komgwaqo, kodwa futhi ukusheshisa inqubekelaphambili kanye nokonga izindleko bekulokhu kukhathaza ochwepheshe bemigwaqo emikhulu. Ubuchwepheshe bokwakha i-asphalt synchronous chip seal buxazulule inkinga ye-slurry yangaphambilini Isendlalelo sokuvala sinokushiyeka okuningi njengezimfuneko eziqinile kuma-aggregate, ukwakhiwa kuthintwa imvelo, ubunzima bokulawula ikhwalithi, kanye nezindleko eziphezulu. Ukwethulwa kwalobu buchwepheshe bokwakha akulula nje ukuthuthukisa ikhwalithi yokwakha nokulondoloza izindleko, kodwa futhi kunesivinini sokwakha esisheshayo kunesendlalelo sokuvala uphawu lwe-slurry. Ngesikhathi esifanayo, ngenxa yokuthi lobu buchwepheshe bunezici zokwakha okulula kanye nokulawula ikhwalithi okulula, kuyadingeka kakhulu ukuthuthukisa ubuchwepheshe bokuvalwa kwe-asphalt synchronous chip seal ezifundazweni ezihlukahlukene zezwe.

Iloli le-synchronous chip sealing iloli lisetshenziselwa ikakhulukazi inqubo yokuvala amatshe endaweni yomgwaqo, ukuvimbela ukungena kwamanzi kwebhuloho kanye nongqimba oluphansi lokuvala. I-synchronous chip seal truck iyisisetshenziswa esikhethekile esingavumelanisa ukusatshalaliswa kwe-asphalt binder netshe, ukuze i-asphalt binder netshe kube nokuxhumana okugcwele kwendawo ngesikhathi esifushane futhi kufinyelele ukunamathela okuphezulu phakathi kwakho. , ilungele ikakhulukazi ukusabalalisa izibophezelo zetiyela ezidinga ukusetshenziswa kwebitumen eguquliwe noma itiyela lerabha.

Ukwakhiwa kokuphepha emgwaqeni akukona nje kuphela ukuzibophezela, kodwa nempilo yabanye. Izinkinga zokuphepha zibaluleke kakhulu kunanoma yini enye. Sethula kuwe imiyalelo yokuphepha yokwakhiwa kwezimoto zokuvala i-asphalt synchronous sealing:
1. Ngaphambi kokusebenza, zonke izingxenye zemoto, i-valve ngayinye ohlelweni lwamapayipi, i-nozzle ngayinye nezinye izinto zokusebenza kufanele zihlolwe. Kuphela uma kungekho amaphutha angasetshenziswa ngokujwayelekile.
2. Ngemuva kokuhlola ukuthi alikho iphutha emotweni yokuvala i-synchronous, shayela imoto ngaphansi kwepayipi yokugcwalisa, qala ubeke wonke ama-valve endaweni evaliwe, uvule i-cap encane yokugcwalisa phezulu kwe-tank, ufake ipayipi yokugcwalisa. , qala ukugcwalisa i-asphalt, bese ufaka uphethiloli Uma usuqedile, vala u-oyela omncane ngokuqinile. Itiyela elengeziwe kufanele lihlangabezane nezidingo zokushisa futhi alikwazi ukugcwaliswa ligcwele kakhulu.
3. Ngemuva kokuthi iloli lokuvalwa kwe-synchronous ligcwele i-asphalt ne-gravel, qala kancane bese ushayela endaweni yokwakha ngesivinini esiphakathi. Ngesikhathi sokuthutha, akekho ovunyelwe ukuma endaweni ngayinye; ukususwa kwamandla kumele kuphele egiyeni, futhi isishisi sinqatshelwe ukusetshenziswa ngenkathi ushayela; wonke ama-valve kufanele avaliwe.
4. Ngemva kokuthunyelwa endaweni yokwakha, uma izinga lokushisa le-asphalt ethangini leloli le-synchronous sealing lingakwazi ukuhlangabezana nezidingo zokufafaza, i-asphalt kufanele ishiswe. Phakathi nenqubo yokushisa kwe-asphalt, iphampu ye-asphalt ingashintshwa ukuze kuzuzwe ukushisa okufanayo.
5. Ngemva kokuba itiyela ethangini lifinyelela izimfuneko zokufafaza, shayela imoto yokuvala ehambisanayo kuze kube yilapho umlomo wombhobho wangemuva usuqhele ngo-1.5 kuya ku-2m ukusuka endaweni yokuqala yokusebenza futhi ume. Ngokwezidingo zokwakha, ungakhetha ukufutha okuzenzakalelayo okulawulwa yideski langaphambili kanye nokufafaza okwenziwa ngesandla okulawulwa ingemuva. Ngesikhathi sokusebenza, akekho ovunyelwe ukuma endaweni ephakathi nendawo, imoto kufanele ishayele ngesivinini esingaguquki, futhi akuvunyelwe ukunyathela i-accelerator.
6. Uma umsebenzi usuqediwe noma indawo yokwakha ishintshwa phakathi nendawo, isisefo, iphampu ye-asphalt, amapayipi kanye nemibhobho kufanele kuhlanzwe.
7. Ngemva kokusebenza kokuhlanza kwesitimela sokugcina sosuku kuqediwe, imisebenzi elandelayo yokuvala kufanele igcwaliswe.
