Ulwakhiwo oluthuthwayo lugxile kwiikhonkco ezahlukeneyo ezifana nokuwelda iiphini, ukupeyinta ngebhitumen, ukuxuba amanzi, ukulungisa isikhunta, ukungcangcazela, ukhuseleko lokukhululwa kwesikhunta, ukuqinisekiswa kobungakanani, kunye nokuchaneka kwamanqaku okulinganisa, kwaye ukuphunyezwa kwenziwa ngokuhambelana ngokungqongqo neemfuno zomenzi wezinto kunye nomzi-mveliso webhoyila.
1. Faka izikhonkwane uze uzibambe
Ngaphambi kokuba kubekho uxinzelelo lwamanzi, iiphini kwiindawo ezifanelekileyo ezifana neendawo zokuwelda zomphezulu wokufudumeza kunye neendawo zokuwelda ezidibeneyo kunye neendawo zokuwelda zomphezulu wokufudumeza ngexesha lenkqubo yokuthutha nokufakela kufuneka zizaliswe. Lungisa izikhonkwane zokuwelda kunye nokubamba ukuqinisekisa ukuba iiphini zicwangciswe ngokwemilinganiselo eyilelweyo. Ngaphambi kokuthulula, faka umaleko wepeyinti ye-asphalt enobukhulu obungaphezulu kwe-1mm kuzo zonke iindawo zesinyithi ezifakwe ngaphakathi, izikhonkwane kunye nezinye iindawo zesinyithi okanye ugoqe izinto ezitshayo.
2. Izithako, ukusasazwa kwamanzi, ulawulo lokuxuba
Izithako ziyalinganiswa kwaye amanzi asasazwa ngokuhambelana neemfuno zencwadi yemiyalelo yomenzi wezinto, kwaye umntu otyunjiweyo unoxanduva lokulinganisa ngokuchanekileyo. Amanzi asetyenziselwa ukuxuba izinto ezixutywayo kufuneka abe ngamanzi acocekileyo (njengamanzi okusela), ane-pH eyi-6 ~ 8. Nika ingqalelo kulandelelwano lokongeza amanzi kunye nexesha lokuxuba nokuxuba. Akuvumelekanga ukongeza amanzi ngokuthanda, kwaye akuvumelekanga ukuqhubela phambili okanye ukwandisa ixesha lokuxuba ngokungakhethiyo. Ubungakanani bamanzi akufuneki bongezwe kwindawo enye, kwaye into exutywayo kufuneka ixutywe ngokupheleleyo. Kubalulekile ukongeza i-fiber yentsimbi kwi-castable ngexesha lenkqubo yokongeza amanzi nokuxuba, kwaye akufuneki ixutywe kwii-agglomerates.
3. Ulawulo lwetemplate
Ukwenza isikhunta esinokusetyenziswa yinkqubo ebaluleke kakhulu, kwaye umgangatho wepleyiti yesikhunta uchaphazela ngqo umgangatho wesikhunta esinokusetyenziswa. Ulawulo lwethempleyithi lugxile ekwamkeleni ukuqina kwayo kunye nokuchaneka kwayo okulinganayo. Ithempleyithi kufuneka iqine kwaye idityaniswe ngokuqinileyo ukuqinisekisa ukuba akukho kushukuma okanye ukuyekelela ngexesha lokugalela. Isikhunta somthi kufuneka sibekelwe ngokwemilinganiselo yejometri yomzobo wokwakha kunye nobukhulu bokugalela, senziwe kwangaphambili kwaye sahlanganiswa, kwaye ujongano luqinile. Isikhunta senziwe ngethempleyithi eyi-15 cm kunye nesikwere somthi, ububanzi obuyi-≤500mm; isikhunta esinobume obukhethekileyo senziwe ngesikwere somthi kwaye sigqunywe ngumphezulu. Ibhodi eneziisentimitha ezintathu, umphezulu uxutywe ngee-agents ezimbini zokukhulula ukuqinisekisa ukuba ubukhulu besikhunta esinokusetyenziswa kwaye umphezulu emva kokwakhiwa uthambile kwaye ucocekile ngaphandle kokufaka imingxuma. Ifom kufuneka ihlolwe kwaye yamkelwe ngaphambi kokwakhiwa.
4. Ulawulo lokuthulula
Xa kugalelwa into ephoswayo, ukuphakama kokutya ngakunye kulawulwa kumgama we-200 ~ 300mm, inxalenye enobukhulu obungaphezulu kwe-50mm igalelwa ngesixhobo sokudlidliza esifakiweyo, kwaye indlela "yokungena ngokukhawuleza nokuphuma kancinci" isetyenziselwa ukudlidliza rhoqo ngexesha lokudlidliza ukuthintela ukugcinwa. Kwingxinano esezantsi kunye nokudlidliza kokuvuza, ixesha lokudlidliza lenqaku ngalinye akufuneki libe lide kakhulu ukuthintela umgubo ocolekileyo ukuba ungadada. Ngexesha lenkqubo yokudlidliza, intonga yokudlidliza akufuneki ibethe ithempleyithi kwaye ihoke izikhonkwane kakhulu. Xa kugalelwa izinto eziphoswayo ezingaphezulu kwe-50mm ubukhulu, indawo engaphezulu kwe-10m2 kufuneka yakhiwe ngamanqaku amabini ngexesha elinye; ukuqinisekisa ukuba izinto ezixutyiweyo zigalelwa ngexesha elichaziweyo, ukugalelwa kwamacandelo angaphantsi kwe-50mm ubukhulu kukhethwa ukuba kube kukwakha okuzilawulayo kunye nokwakha okuzilawulayo okuzilawulayo okuzilawulayo.
5. Ukubhukisha iindawo zokwandisa
Ngenxa yokuba i-expansion coefficient ye-castable ayihambelani ne-expansion coefficient yentsimbi, imalunga nesiqingatha sentsimbi. Ngokubanzi, kukho iindlela ezine zokusombulula ukwandiswa kwe-castable: enye kukupenda ipeyinti ye-asphalt kumphezulu we-pin kunye nesinyithi, ubukhulu abungaphantsi kwe-1mm. Eyesibini yinxalenye enkulu yokuthulula, egalelwa kwiibhloko rhoqo nge-800 ~ 1000 × 400, kwaye izinto zokudibanisa ukwandiswa zincamathiselwa ecaleni ukuze zishiye i-expansion joint. Eyesithathu kukufaka iphepha le-ceramic fiber elinobukhulu be-2mm kumphezulu we-hood, izixhobo zombhobho wezixhobo, kunye neendawo zokungena eludongeni lwesinyithi njengeendawo zokudibanisa ukwandiswa. Okwesine, imela ingasetyenziselwa ukusika isithuba esiphakathi kobukhulu ngexesha lokwakhiwa kweplastiki, okanye umngxuma ungabhobozwa kwiplastiki ukusombulula ingxaki yokwandisa.
