Ukugaya Indlela: Yintoni? Ingaba isebenza kanjani?

Ukugaya iindlela kunokugqalwa njengokungqusha, kodwa kungaphezulu nje kokuvula iindlela. Namhlanje, siza kuntywila kwihlabathi lokugaya iindlela kwaye sifunde ulwazi oluneenkcukacha ezinjengoomatshini, izibonelelo, kunye nokunye.

Yintoni i-Road Milling/Pavement Milling?

I-Pavement milling, ekwabizwa ngokuba yi-asphalt milling, i-cold milling, okanye iplani ebandayo, yinkqubo yokususa inxalenye yendawo egangathiweyo, ukugquma iindlela, iindlela zokuhamba, iibhulorho, okanye iindawo zokupaka. Ngombulelo kwi-asphalt milling, ukuphakama kwendlela akuyi kunyuka emva kokubeka i-asphalt entsha kwaye yonke imonakalo ekhoyo yesakhiwo inokulungiswa. Ngaphezu koko, i-asphalt endala esusiweyo inokuphinda isetyenziswe njengeaggregate yezinye iiprojekthi zendlela yendlela. Ngezizathu ezithe vetshe, funda nje!

IiNjongo zokugaya iindlela

Kukho izizathu ezininzi zokukhetha indlela yokusila. Esinye sezizathu ezibaluleke kakhulu kukurisayikilisha. Njengoko kukhankanyiwe ngasentla, iasphalt endala inokuphinda isetyenziswe njengeaggregate yeeprojekthi zepavement entsha. I-asphalt esetyenzisiweyo, ekwaziwa njenge reclaimed asphalt pavement (RAP), idibanisa i-asphalt endala egayiweyo okanye etyunyuziweyo kunye ne-asphalt entsha. Ukusebenzisa i-asphalt esetyenzisiweyo endaweni ye-asphalt entsha ngokupheleleyo kwindlela yeenyawo kunciphisa isixa esikhulu senkunkuma, konga imali eninzi kumashishini, kwaye kunciphisa ifuthe elibi kokusingqongileyo.

Ngaphandle kokurisayikilishwa, ukugaya indlela kungaphucula umgangatho wemigangatho yendlela kunye nokwandisa ubomi benkonzo, ngaloo ndlela kuphuculwe amava okuqhuba. Imiba ethile enokuthi ilungiswe kwindlela yokusila kukungalingani, umonakalo, ukurula, ukurhangqa, nokopha. Umonakalo wendlela udla ngokubangelwa ziingozi zemoto okanye imililo. I-rutting ithetha imirhubhe ebangelwa kukuhamba kwamavili, okufana neelori ezithwele kakhulu. I-Raveling ibhekisa kwi-aggregate eyahlulwe enye kwenye. Xa i-asphalt iphakama kwindlela, ukopha kwenzeka.

Ngaphezu koko, ukugaya indlela kukulungele ukwenza iirumble strips.

Iintlobo zokugaya iindlela

Kukho iintlobo ezintathu eziphambili zokugaya iindlela zokujongana neentlobo ezahlukeneyo zeemeko. Izixhobo ezizodwa kunye nezakhono ziyafuneka kwindlela nganye yokusila ngokufanelekileyo.

I-Fine-Milling

I-fine milling isetyenziselwa ukuhlaziya i-surface layer ye-pavement kunye nokulungisa umonakalo ongaphezulu. Inkqubo yile ilandelayo: susa i-asphalt yomhlaba eyonakalisiweyo, lungisa umonakalo wesiseko, kwaye ugubungele umphezulu nge-asphalt entsha. Emva koko, ugudileyo kwaye ukhuphe umgangatho we-asphalt entsha.

Ukucwangcisa

Ngokwahlukileyo kwindlela yokusila, ukucwangcisa kudla ngokusetyenziswa ekulungiseni iipropati ezinkulu ezifana neendlela ezinkulu. Injongo yaso kukwakha umgangatho osemgangathweni wendawo yokuhlala, ishishini, izithuthi, okanye izicelo zorhwebo. Inkqubo yokucwangcisa ibandakanya ukususa yonke i-pavement eyonakalisiweyo endaweni yendawo kuphela, usebenzisa amaqhekeza asusiweyo ukudala i-aggregate, kunye nokusebenzisa i-aggregate kwi-pavement entsha.

Micro-Milling

Micro milling, njengoko igama libonisa, ukususa kuphela umaleko obhityileyo (malunga ne-intshi enye okanye ngaphantsi) asphalt endaweni yonke umphezulu okanye kwipavumente. Eyona njongo iphambili yokusila kukulondoloza endaweni yokulungisa. Le yeyona ndlela igqwesileyo yokuthintela indledlana yabahambi ukuba ibe mandundu. Igubu lokusila elijikelezayo lisetyenziswa kwi-micro milling, kunye namazinyo amaninzi okusika i-carbide-tipped, i-aka road milling teeth, ifakwe kwi-drum. La mazinyo okungqusha abekwe ngokwemiqolo ukwenza umphezulu ogudileyo. Nangona kunjalo, ngokungafaniyo namagubu okusila asemgangathweni, ukungqusha okuncinci kungquba kuphela umphezulu ukuya kubunzulu obungekho nzulu, kodwa kusonjululwe iingxaki ezifanayo zendlela.

Inkqubo & oomatshini

Umatshini wokungqusha obandayo wenza i-pavement milling, ekwabizwa ngokuba yi-cold planer, ingakumbi equka igubu lokusila kunye nenkqubo yokuhambisa.

Njengoko kukhankanyiwe ngasentla, igubu lokugaya lisetyenziselwa ukususa kunye nokugaya indawo ye-asphalt ngokujikeleza. Umgqomo wokugaya ujikeleza kwicala elichasene nomatshini wokuhamba, kwaye isantya siphantsi. Iqukethe imiqolo yabaphathi bezixhobo, ephethe amazinyo okusika i-carbide-tipped, akaindlela yokusila amazinyo. Ngamazinyo okusika anqumle umphezulu we-asphalt. Ngenxa yoko, amazinyo okusika kunye nezixhobo zokuphatha izixhobo zikhawuleza ziphele kwaye zifuna ukutshintshwa xa zaphukile. Amathuba anqunyulwa yimpahla yokusila, ukusuka kwiiyure ukuya kwiintsuku. Inani lamazinyo okugaya indlela lichaphazela ngokuthe ngqo iimpembelelo zokugaya. Okukhona, igudile.

Ngexesha lokusebenza, i-asphalt esusiweyo iwela kumhambisi. Emva koko, inkqubo yokuhambisa idlulisela iasphalt endala egayiweyo kwilori eqhutywa ngumntu ephambi kancinane kwesicwangcisi esibandayo.

Ukongeza, inkqubo yokugaya ivelisa ubushushu kunye nothuli, ngoko ke amanzi asetyenziselwa ukupholisa idrum kunye nokunciphisa uthuli.

Emva kokuba umphezulu we-asphalt uhlanjululwe kububanzi obufunwayo kunye nobunzulu, kufuneka ucocwe. Emva koko, i-asphalt entsha iya kubekwa ngokulinganayo ukuqinisekisa ukuphakama okufanayo komphezulu. Iasphalt esusiweyo iya kuphinda isetyenziswe kwiiprojekthi zepavement entsha.

Iingenelo

Kutheni le nto sikhetha ukugaya i-asphalt njengendlela ebalulekileyo yokugcina indlela? Sikhankanye ngasentla. Ngoku, makhe sixoxe ngakumbi ngezizathu eziphambili.

Ukufikeleleka nokuSebenza ngoQoqosho

Enkosi ekusebenziseni iasphalt esetyenzisiweyo okanye ebuyisiweyo, ixabiso lisezantsi ngokweyiphi na indlela yokugaya oyikhethayo. Iikontraka zolondolozo lweendlela zikholisa ukonga iasphalt ehlaziyiweyo kwiiprojekthi zepavumente zangaphambili. Kuphela ngale ndlela, bayakwazi ukunciphisa iindleko kwaye basabonelela ngenkonzo enkulu kubathengi.

Ukuzinza kokusingqongileyo

I-asphalt esusiweyo inokuxutywa nezinye izinto kwaye isetyenziswe kwakhona, ngenxa yoko ayiyi kuthunyelwa kwiindawo zokulahla inkunkuma. Ngokwenyani, uninzi lweeprojekthi zokuhamba kwendlela kunye nokulungiswa zisebenzisa iasphalt ehlaziyiweyo.

Akukho Miba yokuGutyulwa kwamanzi kunye neMiba yokuHamba ngoMphakamo

Unyango olutsha lomphezulu lunokuphakamisa ubude bendlela kunye nokubangela imiba yokuhambisa amanzi. Ngokugaya i-asphalt, akukho mfuneko yokongeza iileya ezininzi ezintsha phezulu kwaye akuyi kubakho zingxaki zesakhiwo ezifana neziphene zokuhambisa amanzi.
