Accurate locating method for lowering pile foundation steel reinforcement cage
The invention relates to an accurate locating method for lowering a pile foundation steel reinforcement cage. The accurate locating method for lowering the pile foundation steel reinforcement cage comprises the steps that two mutual-crossed steel reinforcement cage axis locating ropes are arranged along the diameter of the steel reinforcement cage; one end of a traction rope is connected to a tipof a conical buoy, and the other end of the traction rope retraces and goes upwards again after penetrating the crossing point of the two steel reinforcement cage axis locating ropes and serves as thecontrol end of the traction rope; after the steel reinforcement cage is lowered to the bottom of a pile hole, the control end of the traction rope is lifted and pulled upwards until only the top of the buoy is exposed above the slurry liquid level, and at the moment, the buoy directly faces the center of the steel reinforcement cage; through two mutual-crossed pile hole axis locating ropes on thetop of a pile hole, a plumb bob is lowered on the crossing point position of the two pile hole axis locating ropes; and the steel reinforcement cage is moved through a crane so that the buoy center is aligned with the lower end of the plumb bob, and at the moment, the axis of the steel reinforcement cage coincide with the axis of the pile hole. The accurate locating method for lowering the pile foundation steel reinforcement cage is applicable to lowering construction of pile foundation steel reinforcement cage with excessively-high virtual piles, the method is simple and easy to operate, andin addition, the cost is not increased additionally.
本发明涉及一种桩基钢筋笼下放精确定位方法，沿钢筋笼直径设两根相互交叉的钢筋笼轴心定位绳，将一根牵引绳一端连接一锥形浮标的尖头端，另一端自上而下穿过两钢筋笼轴心定位绳的交叉点后再折返向上，作为牵引绳控制端；钢筋笼下放到桩孔底后，向上提拉牵引绳控制端，直至浮标仅顶部露出在泥浆液面以上，此时浮标正对钢筋笼的中心；在桩孔顶部通过两根相互交叉的桩孔轴心定位绳，在两桩孔轴心定位绳的交叉点处下放一线锤，通过吊机移动钢筋笼，使浮标中心与线锤下端对正，则此时钢筋笼轴心与桩孔轴心重合。本发明适用于虚桩过高的桩基钢筋笼下放施工，方法简单易操作，且不额外增加成本。
