The invention provides a construction method of a cast-in-place pile reinforcement cage lifting appliance capable of being rapidly detached. The construction method comprises the following steps that the length of the lifting appliance is determined according to the actual site construction size; the lifting appliance is assembled on site; the assembled lifting appliance is lowered to the position of the stiffening stirrup of the reinforcement cage, the lifting appliance is adjusted to enable the stiffening stirrup to be arranged in the clamping ring, the inserting rod penetrates through the fixing ring and the hollow pipe and is clamped on the hollow pipe at the upper end of the clamping ring, and the lifting appliance and the reinforcement cage are fixed; the previous step is repeated, and the other lifting appliance is fixed to the reinforcement cage at the position, opposite to the lifting appliance, of the reinforcement cage; the steel pipe penetrates through the lifting lug of the lifting appliance and is lapped on the sleeper; pouring concrete; after pouring is completed, the inserting rod is lifted, and the inserting rod is separated from the clamping ring and lifted out; and the lifting appliance is moved to separate the clamping rings from the stiffening stirrups of the reinforcement cage, and the lifting appliance is lifted out of the reinforcement cage. The construction method can effectively solve the problems of low mounting precision, upward floating of the reinforcement cage, material waste and the like, and improves the mounting quality, the dismounting speed and the like.
本发明提供一种利用可快速拆卸的灌注桩钢筋笼吊具的施工方法,包括以下步骤:根据现场实际施工尺寸确定吊具长度;将吊具进行现场组装;将组装好的吊具下放至钢筋笼的加劲箍筋的位置,调整吊具使得加劲箍筋置于卡环内,将插杆穿过固定环和空心管,卡在卡环上端空心管上,吊具和钢筋笼固定;重复上一步骤,在钢筋笼与吊具相对的位置上将另一吊具与钢筋笼固定好;钢管穿过吊具的吊耳,钢管搭接在枕木上;浇筑混凝土;浇筑完毕后,提拉插杆,使插杆脱离卡环并提出;移动吊具使得卡环脱离钢筋笼的加劲箍筋,将吊具提出钢筋笼。本发明施工方法可有效的解决安装精度低、钢筋笼上浮、材料浪费等问题,提高了安装质量、拆卸速度等。
