Ukwakhiwa kwe-castable kugxile kwiikhonkco ezininzi ezifana ne-pin welding, ukupeyinta ibhitumene, ukuxutywa kwamanzi, ukulungiswa kwesikhunta, ukungcangcazela, ukukhuselwa kokukhululwa kwe-mold, ukuqinisekiswa kobungakanani, kunye nokuchaneka kweendawo zokulinganisa, kunye nokuphunyezwa kuqhutyelwa ngokungqongqo ngokuhambelana neemfuno zezinto eziphathekayo. umenzi kunye nomzi-mveliso webhoyila.
1. Iphini kwaye ubambe ufakelo lwezikhonkwane
Ngaphambi koxinzelelo lwamanzi, izikhonkwane kwiindawo ezichaphazelekayo ezifana ne-welding joints of the heat and welding joints and joints of the warm surface ngexesha lokuthutha kunye nenkqubo yokufakela kufuneka izaliswe. Lungisa i-welding kwaye ubambe izikhonkwane ukuze uqinisekise ukuba izikhonkwane zicwangciswe ngokobuninzi obuyiliweyo. Ngaphambi kokuba ugalele, sebenzisa umaleko wepeyinti ye-asphalt enobunzima obungaphezulu kwe-1mm kuzo zonke iindawo zentsimbi ezifakwe ngaphakathi, izikhonkwane kunye neminye imiphezulu yesinyithi okanye usonge izinto ezinokutsha.
2. Izithako, ukuhanjiswa kwamanzi, ukulawula ukuxuba
Izithako zilinganiswe kwaye amanzi ahanjiswa ngokungqongqo ngokuhambelana neemfuno zencwadana yezinto eziphathekayo zomenzi wezinto eziphathekayo, kwaye umntu okhethiweyo unoxanduva lokulinganisa ngokuchanekileyo. Amanzi asetyenziselwa ukuxuba izinto zokugalela kufuneka abe ngamanzi acocekileyo (afana namanzi okusela), ane pH eyi 6~8. Nika ingqalelo kumyalelo wokongeza amanzi kunye nokuxuba kunye nexesha lokuxuba. Akuvumelekanga ukongeza amanzi ngokuthanda, kwaye akuvumelekanga ukuqhubela phambili okanye ukwandisa ixesha lokuxuba ngokungaqhelekanga. Ubungakanani bamanzi akufunekanga bongezwe kwindawo enye, kwaye i-castable kufuneka ixutywe ngokupheleleyo. Kuyimfuneko ukongeza i-fiber yensimbi kwi-castable ngexesha lenkqubo yokongeza amanzi kunye nokuxuba, kwaye ayiyi kuxutywa kwi-agglomerates.
3.Ulawulo lwetemplate
Ukwenza i-Castable mold yinkqubo ebaluleke kakhulu, kwaye umgangatho we-mold plate uchaphazela ngokuthe ngqo umgangatho we-castable. Ulawulo lwetemplate lujolise ekwamkelweni kokuqina kwayo kunye nokuchaneka komda. Ithemplethi kufuneka iqine kwaye idityaniswe ngokuqinileyo ukuze kuqinisekiswe ukuba akukho kususwa okanye ukukhululeka ngexesha lokugalela. Isikhunta sokhuni kufuneka sibekwe ngokwemilinganiselo yejometri yomzobo wokwakha kunye nobukhulu bokuthululela, i-prefabricated kwaye ihlanganiswe, kwaye i-interface iqinile. Isikhunta senziwe nge-template ye-15 cm kunye nesikwere sokhuni, kunye nobubanzi be-≤500mm; isikhunta esikhethekileyo senziwe kwisikwere somthi kwaye sigqunywe ngebhodi yebhodi ye-Layered ye-centimeter ezintathu, umphezulu uhlanjululwe ngee-agent ezimbini zokukhulula ukuqinisekisa ukuba ubukhulu be-castable kunye nomphezulu emva kokwakhiwa kugudileyo kwaye kucocekile ngaphandle kokugoba. Ifomwork kufuneka ihlolwe kwaye yamkelwe phambi kokwakhiwa.
4.Ukugalela ulawulo
Xa ugalela i-castable, ukuphakama kwesondlo ngasinye kulawulwa kuluhlu lwe-200 ~ 300mm, inxalenye enobunzima obukhulu kuno-50mm igalelwa nge-vibrator efakiweyo, kwaye indlela "yokukhawuleza nokucotha" isetyenziselwa ukungcangcazela ngokuqhubekayo. ngexesha lokungcangcazela ukuthintela ukugcinwa Kumngxuma osezantsi kunye nokungcangcazela okuvuzayo, ixesha lokungcangcazela kwinqanaba ngalinye akufanele libe lide kakhulu ukukhusela umgubo ocolekileyo ukuba ungadada. Ngethuba lenkqubo yokungcangcazela, intonga yokungcangcazela kufuneka ingabetheli itemplate kunye nezikhonkwane ze-hook kakhulu. Xa ugalela ii-castables ezinkulu kune-50mm ubukhulu, indawo enkulu kune-10m2 kufuneka yakhiwe kwiindawo ezimbini ngexesha elinye; ukuqinisekisa ukuba izinto ezixubeneyo zigalelwa ngexesha elichaziweyo, ukugalelwa kwamacandelo angaphantsi kwama-50mm ubukhulu kukhethwa ukuba kukuzilungelelanisa kunye nokwakhiwa kwe-self-flowing castable degassed.
5.Ukugcinwa kwamalungu okwandisa
Ngenxa yokuba i-coefficient yokwandisa i-castable ayihambelani ne-coefficient yokwandiswa kwentsimbi, malunga nesiqingatha sentsimbi. Ngokuqhelekileyo, kukho iindlela ezine zokusombulula ukwandiswa kwe-castable: enye kukupenda ipeyinti ye-asphalt kwipini kunye nentsimbi, ubukhulu abukho ngaphantsi kwe-1mm. Okwesibini yindawo enkulu yokugalela, egalelwa kwiibhloko zonke i-800 ~ 1000 × 400, kunye nokwandiswa kwezinto ezidibeneyo zixutywe ukusuka kwicala ukushiya i-joint yokwandisa. Okwesithathu kukuvuthuza ngephepha le-ceramic fiber enobunzima obuyi-2mm kumphezulu wehood, izifakelo zemibhobho yesixhobo, kunye neendawo zokungena eludongeni lwesinyithi njengamajoyinti okwandisa. Okwesine, imela ingasetyenziselwa ukusika i-gap yesiqingatha sobunzima ngexesha lokwakhiwa kweplastiki, okanye umngxuma unokubethelwa kwiplastiki ukuxazulula ingxaki yokwandisa.
