The invention discloses a reinforcement cage hoisting method for an existing pipeline of an underground diaphragm wall. The reinforcement cage hoisting method comprises the following steps that (1) a main hoist and an auxiliary hoist are in place; (2) the reinforcement cage is hoisted to be 0.3-0.5 m away from the ground, and the main hoist continues to hoist until the reinforcement cage is completely upright; (3) the reinforcement cage is lifted by the main lifting belt to move to the groove entering position and put down, the reinforcement cage is put down to the second lifting point of the main lifting belt, a shackle and a steel wire rope of the second lifting point of the main lifting belt are removed, and after the position of the steel wire rope of the first lifting point of the main lifting belt is adjusted, one end of a standby steel wire rope A and one end of a standby steel wire rope D are fixed to the two sides of the reinforcement cage respectively; and (4) the reinforcement cage continues to be lowered to the position below the pipeline, the other end of the standby steel wire rope A penetrates through the position below the pipeline and a fixed pulley located on the guide wall and then is fixed to the main lifting hook, the other end of the standby steel wire rope D is fixed to the main lifting hook, the main lifting point is released, and the standby steel wire rope A and the standby steel wire rope D are stressed and moved to the position below the pipeline. The method is time-saving, labor-saving, safe and effective in operation.
本发明公开用于地连墙既有管线的钢筋笼吊装方法,包括如下步骤:1)主、副吊就位;2)将钢筋笼吊离地面0.3‑0.5m,主吊继续提升,直至钢筋笼完全直立;3)主吊带载移动钢筋笼至入槽位置下放,钢筋笼下放至主吊第二吊点位置,卸除主吊第二吊点卸扣及钢丝绳,将主吊第一吊点的钢丝绳调整位置后,将备用钢丝绳A和备用钢丝绳D的一端分别固定于钢筋笼的两侧;4)钢筋笼继续下放至管线下方,将备用钢丝绳A的另一端穿过管线下方和位于导墙上的固定滑轮后固定于主吊吊钩上,备用钢丝绳D另一端固定于主吊吊钩上,释放主吊吊点,备用钢丝绳A和备用钢丝绳D受力,移动至管线下方。本发明方法操作省时省力,安全、有效。
