Cast-in-situ bored pile reinforcement cage hoisting and lowering device and construction method
The invention relates to the technical field of cast-in-place pile reinforcement cage lowering, in particular to a cast-in-place bored pile reinforcement cage hoisting and lowering device and a construction method.The cast-in-place bored pile reinforcement cage hoisting and lowering device comprises a base, a positioning hole is formed in the base, and a positioning claw is horizontally and slidably connected to the base and provided with two rotating wheels; the two rotating wheels are wrapped with a conveying crawler belt used for abutting against the reinforcement cage. The base is installed at a pile hole, the positioning hole and the pile hole are coaxially and right opposite, the reinforcement cage penetrates through the positioning hole, the positioning claw slides to clamp and position the reinforcement cage, the reinforcement cage and the pile hole are coaxially and right opposite, when the positioning claw clamps the reinforcement cage, the conveying crawler belt abuts against the reinforcement cage, and the movement direction of the conveying crawler belt is consistent with the movement direction of the reinforcement cage. And the reinforcement cage is gradually lowered to drive the conveying crawler belt and the rotating wheel to rotate, so that the friction force between the conveying crawler belt and the reinforcement cage is reduced, the conveying crawler belt is protected, meanwhile, lowering of the reinforcement cage is not affected, and the position precision of the reinforcement cage in the lowering process can also be guaranteed.
本申请涉及灌注桩钢筋笼下放的技术领域，尤其是涉及钻孔灌注桩钢筋笼吊装下放装置及施工方法，包括基座，基座上开设有定位孔，基座上水平滑动连接有定位爪，定位爪设有两个转动轮，两个转动轮外包裹有用于与钢筋笼抵触的输送履带。基座安装于桩孔处，并使得定位孔与桩孔同轴正对，钢筋笼穿过定位孔，定位爪滑动对钢筋笼进行夹持定位，使得钢筋笼与桩孔同轴正对，定位爪对钢筋笼夹紧时，输送履带与钢筋笼抵触，且输送履带的运动方向与钢筋笼的运动方向一致。钢筋笼逐渐下放，带动输送履带和转动轮转动，从而减小输送履带和钢筋笼之间的摩擦力，对输送履带进行防护，同时也不会影响钢筋笼的下放，也能够保证钢筋笼在下放过程中的位置精度。
