Semi-cantilever type tower crane foundation construction method
The invention discloses a semi-cantilever type tower crane foundation construction method which comprises the following steps: before a foundation pit is excavated, driving a foundation pit support pile; two pairs of tower crane foundation piles are driven into the tower crane foundation design position, so that the two pairs of tower crane foundation piles are located in a foundation pit fat groove and outside a foundation pit correspondingly; erecting a top beam at the top of the foundation pit support pile; a tower crane foundation is erected on the two pairs of tower crane foundation piles, so that the tower crane foundation is supported on the top beam; the foundation pit is excavated to the designed height, and the tower crane foundation cantilever piles are formed by the pair of tower crane foundation piles located in the foundation pit fat groove; and ground hardening is conducted at the position, corresponding to the tower crane foundation cantilever pile, in the foundation pit fat groove, and the construction efficiency is improved through the half-cantilever type tower crane foundation construction method.
本发明公开了一种半悬臂式塔吊基础施工方法，包括步骤：在基坑开挖前，打入基坑支护桩；在塔吊基础设计位置处打入两对塔吊基础桩，使两对所述塔吊基础桩分别位于基坑肥槽内以及基坑外；在所述基坑支护桩顶部支设冠梁；在两对所述塔吊基础桩上支设塔吊基础，使所述塔吊基础支撑在所述冠梁上；开挖基坑至设计高度，使位于基坑肥槽内的一对所述塔吊基础桩形成塔吊基础悬臂桩；在所述基坑肥槽内对应于所述塔吊基础悬臂桩的位置处进行地面硬化，通过所述半悬臂式塔吊基础施工方法，提高了施工效率。
