Itekhnoloji yothintelo lokugcinwa kwe-asphalt ikhonkrithi kwipavement
Okokuqala, intsingiselo yokukhusela ukugcinwa kwesakhiwo se-asphalt yekhonkrithi ye-asphalt yaziswa, kwaye uphando lwangoku, uphuhliso kunye nesimo sokusetyenziswa kokugcinwa kokuthintela ulwakhiwo lwe-asphalt yekhonkrithi ye-asphalt ekhaya nakwamanye amazwe ishwankathelwa. Iindlela zokwakha ezisetyenziswa ngokuqhelekileyo zokukhusela ukugcinwa kwesakhiwo se-asphalt yekhonkrithi ye-asphalt yaziswa, kwaye i-post-treatment kunye neminye imiba ephambili yokukhusela ukugcinwa kwesakhiwo se-asphalt yekhonkrithi iyahlalutywa kwaye ishwankathelwe, kwaye uphuhliso lwexesha elizayo lulindelwe.
Ulondolozo lothintelo
Ukugcinwa kothintelo kubhekiselele kwindlela yokugcina ephunyezwayo xa isakheko sepavumente singekamoshakali. Iphucula imeko yokusebenza yesakhiwo se-pavement kunye nokulibazisa umonakalo we-asphalt pavement ngaphandle kokunyusa umthamo wokuthwala izakhiwo. Xa kuthelekiswa neendlela zokugcinwa kwendabuko, ukugcinwa kothintelo lusebenza ngakumbi kwaye lufuna ukucwangciswa okufanelekileyo ukufezekisa umphumo oyifunayo.
Ukusukela ngo-2006, owayesakuba nguMphathiswa wezoThutho uye wakhuthaza ukusetyenziswa kogcino lothintelo kwilizwe lonke. Kule minyaka ilishumi idlulileyo, abasebenzi bokulungiswa koohola bendlela belizwe lam baye baqalisa ukwamkela nokusebenzisa ulondolozo lothintelo, kwaye ubugcisa bogcino lothintelo buye bakhula ngakumbi nangakumbi. Ngexesha "leSicwangciso seMinyaka emiHlanu yeshumi elineSibini", umyinge wogcino lothintelo kwiiprojekthi zolondolozo lwelizwe lam lonyuke ngeepesenti ezintlanu ngonyaka, kwaye lufumene iziphumo ezimangalisayo zokusebenza kwendlela. Nangona kunjalo, ngeli nqanaba, umsebenzi wokukhusela wokukhusela awukavuthwa, kwaye kusekho iindawo ezininzi ekufuneka zifundwe. Kuphela ngokuqokelelwa okuninzi kunye nophando olunokuthi itekhnoloji yogcino lothintelo ikhule ngakumbi kwaye ifumane iziphumo ezingcono zokusetyenziswa.
Iindlela eziphambili zokugcinwa kokuthintela
Kwilizwe lam lokugcinwa kobunjineli bendlela yelizwe, ngokwesikali kunye nobunzima beprojekthi yokulondoloza, iprojekthi yokulondoloza yahlulahlulwe ibe: ukugcinwa, ukulungiswa okuncinci, ukulungiswa okuphakathi, ukulungiswa okukhulu kunye nokulungiswa, kodwa akukho didi lwahlukileyo lokugcinwa kokukhusela, okuya kuthi. kuchaphazela kakhulu ukuphunyezwa kweeprojekthi zolondolozo lothintelo. Ngoko ke, kuphuhliso lolondolozo lwexesha elizayo, ukugcinwa kokukhusela kufuneka kufakwe kwi-scope yokulondoloza. Okwangoku, iindlela zokwakha eziqhele ukusetyenziswa ekhaya nakwamanye amazwe ukwenzela ukugcinwa kothintelo lwesakhiwo se-asphalt yekhonkrithi yesamente ibandakanya ukutywinwa, ukutywinwa kodaka lwe-micro-surfacing, ukutywinwa kwenkungu kunye nokutywinwa kwamatye atyunyuziweyo.
Ukutywinwa kubandakanya iindlela ezimbini: i-grouting kunye ne-grouting. I-Grouting kukusebenzisa iglu yobunjineli yokutywinwa ngokuthe ngqo kwindawo apho iintanda zenzeka khona kwindlela. Ekubeni iintanda zitywinwe ngeglue, ubungakanani beentsimbi abukwazi ukuba bukhulu kakhulu. Le ndlela ifanelekile kuphela kwizifo ezinezifo ezincinci kunye nobubanzi obuncinci bokuqhekeka. Xa kulungiswa, i-gel ene-viscoelasticity efanelekileyo kunye nokuzinza kweqondo lokushisa eliphezulu kufuneka isetyenziswe ukunyanga iintambo, kunye neengqungquthela ezibonakala zifuna ukuphathwa ngexesha. Ukutywinwa kubhekiselele ekufudumezeni indawo eyonakeleyo yendlela kunye nokuyisika ivuleke, kwaye emva koko usebenzisa i-sealant ukutywina i-seams kwi-grooves.
Itekhnoloji ye-Slurry yokutywina i-micro-surface ibhekisa kwindlela yokusasaza izinto ezixubeneyo ezenziwe ngokuxuba ibakala elithile lelitye, i-asphalt e-emulsified, amanzi, kunye nokuzalisa kwindlela yomgwaqo usebenzisa i-slurry sealer. Le ndlela inokuphucula ngokufanelekileyo indlela yokusebenza kwendlela, kodwa ayifanelekanga ukunyanga izifo zendlela kunye nezifo ezinkulu.
Itekhnoloji yokutywinwa kwenkungu isebenzisa isisasazo se-asphalt ukutshiza i-asphalt eguquguqukayo engenekayo kakhulu kwindlela yokwenza umaleko wendlela ongenamanzi. Uluhlu olusandul 'ukusekwa lwamanzi olungenamanzi lunokuphucula ukuxhathisa kwamanzi kwindlela kunye nokuthintela ngokufanelekileyo umswakama ukuba ungonakalise ngakumbi isakhiwo sangaphakathi.
Itekhnoloji ye-Chip seal isebenzisa isitshizi esizenzekelayo ukufaka isixa esifanelekileyo se-asphalt kumphezulu wendlela, emva koko isasaze igrabile yesayizi ethile kwi-asphalt, kwaye ekugqibeleni isebenzisa irola yetayara ukuyiqengqa imile. Umphezulu wendlela ephathwa ngeteknoloji ye-chip seal iphucule kakhulu ukusebenza kwayo kwe-anti-skid kunye nokuxhathisa kwamanzi.
