Anti-floating device for cast-in-situ bored pile reinforcement cage
The invention discloses a cast-in-situ bored pile reinforcement cage anti-floating device which comprises a device body, the device body is provided with clamping pieces and telescopic pieces, the device body is symmetrically arranged on the two sides of a reinforcement cage through the clamping pieces, and the device body is connected with the inner wall of a pile hole through the telescopic pieces. The device body is connected with a controller through a connecting line, and the controller is connected with and controls the clamping piece. A controllable telescopic anti-floating device is adopted, the device is fixed in the reinforcement cage, pressure is symmetrically applied to the inner wall of the pile hole, the friction force between the inner wall of the pile hole and the anti-floating device is used for resisting buoyancy borne by the reinforcement cage, the accident that the reinforcement cage floats upwards is avoided, and the pile forming quality and the pile body strength are guaranteed.
本发明公开了一种钻孔灌注桩钢筋笼抗浮装置，包括装置主体，所述装置主体设置夹持件与伸缩件，所述装置主体通过所述夹持件对称设置在钢筋笼的两侧，所述装置主体通过所述伸缩件与桩孔的内壁连接，所述装置主体通过连接线与控制器连接，所述控制器连接并控制所述夹持件。本发明中采用一种可控的伸缩式抗浮装置，该装置固定于钢筋笼中，对称地向桩孔的内壁施加压力，利用桩孔的内壁与抗浮装置之间的摩擦力，抵抗钢筋笼受到的浮力，避免钢筋笼上浮的事故发生，保证成桩质量和桩体强度。
