Salvage method for hole collapse pile foundation reinforcement cage
The invention discloses a collapsed hole pile foundation reinforcement cage fishing method. The method comprises the following construction steps that S1, construction preparation is conducted, specifically, a reinforcement fishing device is installed on a drill rod square head of a rotary drilling rig; s2, a reinforcement cage is fixed, specifically, a reinforcement fishing device is hoisted downwards to the bottom of the hole collapse pile foundation along the side wall of the reinforcement cage through a rotary drilling rig, and a twisting claw hook of the reinforcement fishing device makes contact with a pile foundation reinforcement hole; s3, twisting off: twisting off the pile foundation steel bars from the bottom through rotation of the rotary drilling rig; and S4, salvaging: salvaging the collapsed hole pile foundation reinforcing steel bars through ascending of the rotary drilling rig. The collapsed hole pile foundation reinforcement cage salvage method can quickly break and salvage collapsed hole pile foundation reinforcements, reduce the construction time, reduce the construction difficulty and save the construction cost.
本发明公开了一种塌孔桩基钢筋笼打捞方法，包括以下施工步骤：S1：施工准备：将钢筋打捞装置安装在旋挖钻机的钻杆方头上；S2：固定钢筋笼：通过旋挖钻机将钢筋打捞装置下吊沿钢筋笼侧壁下放至塌孔桩基底部，使钢筋打捞装置的绞抓钩接触桩基钢筋孔；S3：绞断：通过旋挖钻机的旋转，将桩基钢筋从底部绞断；S4：打捞：通过旋挖钻机上升将塌孔桩基钢筋进行打捞。塌孔桩基钢筋笼打捞方法能够快速搅断、打捞塌孔桩基钢筋，减少施工时长，降低施工难度，节约施工成本。
