6, kom tsis txhob dai xuab zeb, dai xuab zeb los yog cantilever xuab zeb, yooj yim hauv core, box thiab test. Kev paub tau hais tias dai xuab zeb hauv lub thawv, nchuav yoojyim rau lub cev. Nws tsis yooj yim los tso tus tub ntxhais hanging rau ntawm ib nrab hnub. Cantilever sand core yog tsis ruaj khov, yooj yim mus skew nyob rau hauv qhov kev txiav txim ntawm hlau buoyancy, nws yuav tsum sim kom tsis txhob.

7, yuav tsum yog lub npov txoj hauj lwm, txoj hauj lwm casting thiab qhov chaw ua hauj lwm ua kom txias txias. Tig lub pwm tsis yog tsuas muaj ntau npaum li cas ntawm kev ua haujlwm, tab sis kuj yooj yim ua rau cov xuab zeb hauv kev txav, tawm ntawm cov xuab zeb, thiab txawm tua hluav taws thiab lwm yam teeb meem.
