To avoid the rebar cage uplifts, the speed of concrete casting should be lowered down when the concrete is cast to about 1m under the rebar cage's bottom; when the casting progresses to 4m above the bottom of the rebar cage the tremie should be lifted up to ensure it's bottom is 2m above the rebar cage's one, and then the normal casting speed can be resumed.

为防止钢筋骨架上浮，当灌注砼顶面距钢筋骨架底面1m左右时，应降低砼灌注速度，当砼上升至钢筋骨架底面4m以上时，提升导管，使其底口高于骨架底部2m以上，即可恢复正常砼灌注速度。
