Ukwakhiwa kwe-Castable kugxila ekuxhumaneni okuningana njengokushisela amaphini, ukupenda nge-bitumen, ukuxuba amanzi, ukulungisa isikhunta, ukudlidliza, ukuvikelwa kokukhululwa kwesikhunta, ukuqinisekiswa kosayizi, kanye nokunemba kwamaphuzu okulinganisa, futhi ukuqaliswa kwenziwa ngokuhambisana ngokuqinile nezidingo zomkhiqizi wezinto zokwakha kanye nefektri yebhoyila.
1. Faka izipikili bese uzibamba
Ngaphambi kokucindezela kwamanzi, amaphini ezindaweni ezifanele njengezihlanganisi zokushisela zobuso bokushisa kanye nezihlanganisi zokushisela ezihlanganisiwe kanye nezihlanganisi zobuso bokushisa ngesikhathi senqubo yokuthutha nokufaka kufanele agcwaliswe. Lungisa izipikili zokushisela bese ubamba ukuqinisekisa ukuthi amaphini ahlelwe ngokwezinga eliklanywe ngalo. Ngaphambi kokuthulula, faka ungqimba lopende we-asphalt obukhulu obungu-> 1mm kuzo zonke izingxenye zensimbi ezifakiwe, izipikili nezinye izindawo zensimbi noma ugoqe izinto ezivuthayo.
2. Izithako, ukusatshalaliswa kwamanzi, ukulawula ukuxuba
Izithako ziyakalwa futhi amanzi asatshalaliswa ngokuhambisana nezidingo zencwadi yezinto zokwakha yomenzi wezinto, futhi umuntu oqokiwe unesibopho sokulinganisa okunembile. Amanzi asetshenziselwa ukuxuba izinto ezifakwayo kumele abe ngamanzi ahlanzekile (njengamanzi okuphuza), ane-pH engu-6 ~ 8. Naka ukuhleleka kokufaka amanzi kanye nesikhathi sokuxuba nokuxuba. Akuvunyelwe ukwengeza amanzi ngokuthanda, futhi akuvunyelwe ukuqhubekisela phambili noma ukwandisa isikhathi sokuxuba ngokunganaki. Inani lamanzi akumelwe lifakwe endaweni eyodwa, futhi into efakwayo kumele ixutshwe ngokuphelele. Kuyadingeka ukwengeza i-fiber yensimbi ku-castable ngesikhathi senqubo yokwengeza amanzi nokuxuba, futhi akufanele ixutshwe ngama-agglomerate.
3. Ukulawula ithempulethi
Ukwenza isikhunta esithungwayo kuyinqubo ebaluleke kakhulu, futhi ikhwalithi yepuleti lesikhunta ithinta ngqo ikhwalithi yesikhunta esithungwayo. Ukulawulwa kwethempulethi kugxile ekwamukelweni kokuqina kwayo kanye nokunemba kwayo. Ithempulethi kumele iqine futhi ihlanganiswe kahle ukuqinisekisa ukuthi akukho ukugudluka noma ukukhululeka ngesikhathi sokuthulula. Isikhunta sokhuni kufanele sibekwe ngokwezilinganiso zejometri zomdwebo wokwakha kanye nobukhulu bokuthulula, silungiswe futhi sihlanganiswe, futhi isixhumi siqinile. Isikhunta senziwe ngethempulethi engu-15 cm kanye nesikwele sokhuni, ububanzi obungu-≤500mm; isikhunta esinomumo okhethekile senziwe ngesikwele sokhuni futhi simbozwe ubuso. Ibhodi elingamasentimitha amathathu elinezingqimba, ubuso bugcotshwa ngezinto ezimbili zokukhulula ukuqinisekisa ukuthi ubukhulu besikhunta esithungwayo kanye nobuso ngemva kokwakhiwa bubushelelezi futhi buhlanzekile ngaphandle kokufaka imigodi. Ifomu kumele lihlolwe futhi lamukelwe ngaphambi kokwakhiwa.
4. Ukulawula ukuthulula
Uma kuthululwa okusanhlamvu, ukuphakama kokudla ngakunye kulawulwa ebangeni elingu-200 ~ 300mm, ingxenye enobukhulu obungaphezu kuka-50mm ithululwa nge-vibrator efakiwe edlidliza, futhi indlela "yokungena ngokushesha nokuphuma kancane" isetshenziselwa ukudlidliza njalo ngesikhathi sokudlidliza ukuvimbela ukugcinwa. Ukuze kube nokudlidliza komgodi ongezansi nokuvuza, isikhathi sokudlidliza sephuzu ngalinye akufanele sibe side kakhulu ukuvimbela impuphu ecolekileyo ukuthi ingantanti. Ngesikhathi senqubo yokudlidliza, induku yokudlidliza akumele ishaye ithempulethi futhi ibambe izipikili kakhulu. Uma kuthululwa okusanhlamvu okungaphezu kuka-50mm ubukhulu, indawo engaphezu kuka-10m2 kufanele yakhiwe ngamaphuzu amabili ngesikhathi esisodwa; ukuqinisekisa ukuthi izinto ezixubile zithululwa ngaphakathi kwesikhathi esibekiwe, ukuthululwa kwezingxenye ezingaphansi kuka-50mm ubukhulu kungcono ukuthi kube ukwakhiwa okuzilinganisayo kanye nokwakhiwa okuzihambisayo okuzenzakalelayo okusanhlamvu okusanhlamvu okusanhlamvu.
5. Ukubhukha amalunga okunwetshwa
Ngenxa yokuthi i-coefficient yokwandisa ye-castable ayihambisani ne-coefficient yokwandisa yensimbi, cishe isigamu saleyo yensimbi. Ngokuvamile, kunezindlela ezine zokuxazulula ukwanda kwe-castable: eyodwa ukupenda upende we-asphalt phezu kwephini kanye nobuso bensimbi, ubukhulu bungaphansi kuka-1mm. Esesibili yingxenye yokuthulula yendawo enkulu, ethelwa ngamabhulokhi njalo ngo-800 ~ 1000 × 400, futhi izinto zokuhlanganisa ezinwetshiwe zinamathiselwa ohlangothini ukuze zishiye i-expansion joint. Esesithathu ukubopha iphepha le-ceramic fiber elinobukhulu obungu-2mm ebusweni be-hood, izinto zokufaka amapayipi ezinsimbi, kanye nezingxenye zokungena odongeni lwensimbi njengezihlanganisi zokunwetshwa. Okwesine, ummese ungasetshenziswa ukusika igebe lobukhulu obuyingxenye ngesikhathi sokwakhiwa kwepulasitiki, noma imbobo ingabhobozwa epulasitikini ukuxazulula inkinga yokwandisa.
