Ukwakhiwa kwe-castable kugxile ezixhumanisini ezimbalwa ezifana nokushisela iphini, ukudweba itiyela, ukuxuba amanzi, ukulungisa isikhunta, ukudlidliza, ukuvikela ukukhishwa kwesikhunta, ukuqinisekiswa kosayizi, nokunemba kwamaphoyinti okulinganisa, futhi ukuqaliswa kwenziwa ngokuhambisana nezidingo zezinto ezibonakalayo. umkhiqizi kanye nemboni yokubilisa.
1. Phina futhi ubambe ukufakwa kwezinzipho
Ngaphambi kokucindezelwa kwamanzi, izikhonkwane ezindaweni ezithintekayo ezifana nezihlanganisi zokushisela endaweni yokushisa kanye nezihlanganisi ze-welding ezihlangene kanye nezihlanganisi zendawo yokushisa ngesikhathi sokuthutha kanye nenqubo yokufaka kufanele zigcwaliswe. Lungisa i-welding futhi ubambe izipikili ukuze uqinisekise ukuthi izikhonkwane zihlelwe ngokuvumelana nobuningi obuklanyelwe. Ngaphambi kokuthela, sebenzisa ungqimba lukapende lwetiyela olunogqinsi luka-> 1mm kuzo zonke izingxenye zensimbi ezishumekiwe, izinzipho nezinye izindawo zensimbi noma bopha izinto ezivuthayo.
2. Izithako, ukusatshalaliswa kwamanzi, ukulawula ukuxuba
Izithako ziyakalwa futhi amanzi asatshalaliswa ngokuhambisana ngokuqinile nezidingo zemanuwali yezinto ezibonakalayo zomkhiqizi wezinto ezibonakalayo, futhi umuntu oqokiwe unesibopho sokulinganisa okunembile. Amanzi asetshenziselwa ukuxuba izinto zokugaywa kumele abe amanzi ahlanzekile (njengamanzi okuphuza), ane-pH engu-6~8. Naka ukuhleleka kokwengeza amanzi kanye nesikhathi sokuxuba nokuxuba. Akuvunyelwe ukwengeza amanzi ngokuthanda kwakho, futhi akuvunyelwe ukuqhubekela phambili noma ukunweba isikhathi sokuxuba ngokungafanele. Inani lamanzi akufanele lifakwe endaweni eyodwa, futhi okugaywayo kufanele kuhlanganiswe ngokugcwele. Kudingekile ukwengeza i-fiber yensimbi ku-castable ngesikhathi senqubo yokwengeza amanzi nokuxuba, futhi akufanele ihlanganiswe kuma-agglomerates.
3.Ukulawula isifanekiso
Ukwenza isikhunta esisansimbi kuyinqubo ebucayi kakhulu, futhi ikhwalithi yepuleti lesikhunta ithinta ngqo ikhwalithi ye-castable. Ukulawulwa kwesifanekiso kugxile ekwamukelweni kokuqina nokunemba kobukhulu baso. Isifanekiso kufanele siqine futhi sihlanganiswe ngokuqinile ukuze kuqinisekiswe ukuthi akukho ukugudluka noma ukuxega ngesikhathi sokuthululwa. Isikhunta sokhuni kufanele sibekwe ngokuhambisana nobukhulu bejiyomethri bomdwebo wokwakha kanye nobukhulu bokuthulula, okwenziwe ngaphambili futhi kuhlanganiswe, futhi isikhombimsebenzisi siqinile. Isikhunta senziwe ngesifanekiso se-15 cm nesikwele sokhuni, esinobubanzi obungu-≤500mm; isikhunta esimise okukhethekile senziwe ngesikwele sokhuni futhi simbozwe ngebhodi Lendlalelo elingamasentimitha amathathu, indawo engaphezulu ixutshwa ngama-agent amabili okukhipha ukuze kuqinisekiswe ubukhulu be-castable kanye nobuso ngemuva kokwakhiwa bushelelezi futhi buhlanzekile ngaphandle komgodi. Ifomu lesicelo kufanele lihlolwe futhi lamukelwe ngaphambi kokwakhiwa.
4.Ukulawula ukuthela
Lapho uthela okuphonswayo, ukuphakama kokuphakelayo ngakunye kulawulwa ebangeni lika-200~300mm, ingxenye enogqinsi olungaphezu kuka-50mm ithululwa ngesidlidlizi esifakiwe, futhi indlela “yokusheshisa ukungena nokuphuma kancane” isetshenziselwa ukudlidliza ngokuqhubekayo. ngesikhathi sokudlidliza ukuze uvimbele ukugcinwa Ngembobo ephansi kanye nokudlidliza kokuvuza, isikhathi sokudlidliza sephuzu ngalinye akufanele sibe side kakhulu ukuvimbela impushana ukuba ingantanti. Phakathi nenqubo yokudlidliza, induku yokudlidliza akumele ishaye isifanekiso futhi ihuke izinzipho kakhulu. Lapho uthela ama-castable amakhulu kuno-50mm ubukhulu, indawo enkulu kuno-10m2 kufanele yakhiwe ezindaweni ezimbili ngesikhathi esisodwa; ukuze kuqinisekiswe ukuthi izinto ezixubile zithelwa phakathi nesikhathi esinqunyiwe, ukuthululwa kwezingxenye ezingaphansi kuka-50mm ubukhulu kukhethwa ukuba kube ukwakhiwa kwe-self-leveling futhi okuzenzakalelayo kwe-Degassed self-flowing castable.
5.Ukugcinwa kwamalunga okunwetshwa
Ngenxa yokuthi i-coefficient yokwandisa ye-castable ayihambisani ne-coefficient yokwandisa yensimbi, cishe ingxenye yaleyo yensimbi. Ngokuvamile, kunezindlela ezine zokuxazulula ukunwetshwa kwe-castable: eyodwa ukudweba upende we-asphalt phezu kwephini kanye nensimbi, ubukhulu abukho ngaphansi kuka-1mm. Okwesibili ingxenye enkulu yokuthulula, ethelwa ngamabhulokhi njalo ngo-800 ~ 1000×400, futhi izinto ezihlangene zokunweba zinamathiselwe ohlangothini ukuze zishiye ukujoyina. Okwesithathu ukuvunguza iphepha lefibre ye-ceramic enogqinsi luka-2mm ngaphezulu kwehood, izixhumi zepayipi lezinsimbi, nezingxenye zokungena ezindongeni zensimbi njengamajoyinti okunweba. Okwesine, ummese ungasetshenziswa ukusika igebe lokuqina kwesigamu ngesikhathi sokwakhiwa kwepulasitiki, noma umgodi ungabhobozwa epulasitiki ukuxazulula inkinga yokwandisa.
