The invention provides a prefabricated stand column in-plant overturning method. The method comprises the steps that an overturning area is arranged, wherein the overturning area comprises a foundation pit, the foundation pit is defined by side walls on the four sides, the side walls can support a prefabricated stand column, and the interior of the foundation pit is filled with sandy soil; the prefabricated stand column is overturned to a horizontal state from a vertical state, wherein the prefabricated stand column is vertically hoisted and moved to the position above one side wall of the foundation pit, and one side of the bottom of the prefabricated stand column is aligned with the side wall; the prefabricated stand column is lowered, one side of the bottom of the prefabricated stand column is supported on the side wall, and the other side of the bottom of the prefabricated stand column is suspended above the sandy soil; the prefabricated stand column continues to be lowered, the bottom of the prefabricated stand column overturns towards the interior of the foundation pit due to single-side stress, and the other side of the bottom of the prefabricated stand column is located inthe sandy soil; and under the traction of a hoisting device, the prefabricated stand column continues to be overturned till the prefabricated stand column completely lies in the foundation pit, and overturning of the prefabricated stand column from the vertical state to the horizontal state is completed. According to the prefabricated stand column in-plant overturning method, the overturning areais simple in component and easy and convenient to operate, and the effect of protecting the appearance of the prefabricated stand column is achieved.
本发明提供一种预制立柱厂内翻转的方法,包括设置翻转区域:翻转区域包括基坑,基坑由四边侧墙围成,侧墙能支撑预制立柱,在基坑的内部填充沙土;将预制立柱由竖直状态翻转至水平状态:将预制立柱竖向起吊,并移动至基坑的一边侧墙上方,将预制立柱的底部一侧对准侧墙;将预制立柱下放并使预制立柱的底部一侧支撑于侧墙上,且另一侧悬空于沙土的上方;将预制立柱继续下放,预制立柱的底部由于单侧受力从而向基坑内翻转,使预制立柱的底部的另一侧位于沙土内;在吊装装置的牵引下继续翻转预制立柱,直至预制立柱完全平躺于基坑内,完成预制立柱由竖直状态到水平状态的翻转。本发明翻转区域构件简单、操作简便,起到保护预制立柱外观的作用。
