Anti-floating structure suitable for mechanical construction of vertical shaft and construction method of anti-floating structure
The anti-floating structure comprises a mechanical method construction vertical shaft wall and inclined uplift piles arranged in an inclined mode, the inclined uplift piles are connected with the mechanical method construction vertical shaft wall through connecting beams, the bottom of the mechanical method construction vertical shaft wall is sealed through a bottom sealing structure, and a vertical shaft bottom plate is arranged above the bottom sealing structure. According to the construction method, when the vertical shaft is constructed through the mechanical method, according to the anti-floating requirement of the vertical shaft, one or two of external expansion of the bottom sealing structure and the oblique uplift piles are selected for anti-floating. The anti-floating measure and mechanical construction of the vertical shaft have good adaptability, the self weight and frictional resistance of the soil body are fully utilized to resist floating, the effect of the uplift pile is played to the greatest extent, the scale of the vertical shaft is prevented from being increased, and good economical efficiency is achieved.
本发明提供一种适应机械法施工竖井的抗浮结构，包括机械法施工竖井井壁、斜向设置的斜向抗拔桩，斜向抗拔桩通过连梁与机械法施工竖井井壁相连，所述机械法施工竖井井壁的底部采用封底结构封底，所述封底结构上方设有竖井底板。本发明还提供一种适应机械法施工竖井的抗浮结构施工方法：采用机械法施工竖井时，根据竖井的抗浮需求，选择封底结构外扩、斜向抗拔桩其中一种或两种进行抗浮。本发明提供的抗浮措施与机械法施工竖井具有较好适应性，充分利用土体的自重和摩阻力抗浮，最大可能发挥抗拔桩的效用，避免了增加竖井规模，具有较好的经济性。
