Reinforcement cage floating control device for cast-in-place pile of pipe rolling machine and construction method of reinforcement cage floating control device
The invention discloses a reinforcement cage floating control device for a cast-in-place pile of a pipe twisting machine and a construction method of the reinforcement cage floating control device. A positioning ring is arranged in the middle of the reinforcement cage floating control device, a plurality of back pressure assemblies are arranged on the inner side of the positioning ring, a plurality of suspender assemblies are arranged on the outer side of the positioning ring, and two flanges are welded to the outer side of a pile casing on the uppermost portion; the distance between the two flanges is slightly larger than the distance between the two adjacent clamping teeth, and during construction, the movable rod overturns outwards and downwards so that the two adjacent clamping teeth on the movable rod can clamp the flanges on the outer side of the cylinder wall of the protective cylinder to provide counter force for resisting upward floating of a reinforcement cage. After the reinforcement cage passes through the positioning ring in the pile casing in a one-way mode, the pressing plate resets to obliquely press and abut against the stirrup at the upper end of the reinforcement cage downwards and outwards, then the reinforcement cage is kept below the positioning ring all the time and cannot retreat, and therefore the reinforcement cage is effectively prevented from floating upwards. The method solves the problem that the anti-floating effect of the reinforcement cage is unstable by adopting existing remedial measures in the concrete pouring construction of the cast-in-place pile of the pipe twisting machine in a construction site.
本发明公开了一种用于搓管机灌注桩的钢筋笼上浮控制装置及其施工方法，其中部为定位环，定位环的内侧为多道反压组件，定位环的外侧为多道吊杆组件，在最上部一节护筒外侧焊接形成两道凸缘，两道凸缘的间距略大于相邻的两道卡齿之间的间距，在施工时，活动杆向外向下翻转以令活动杆上的相邻两卡齿夹持于护筒的筒壁的外侧的凸缘以为抵抗钢筋笼的上浮提供反力，之后钢筋笼单向通过护筒内定位环后压板复位以斜向下向外压抵钢筋笼的上端箍筋，进而始终保持钢筋笼在定位环的下方，不可回退，从而有效避免钢筋笼上浮。本发明解决了建筑工地内搓管机灌注桩混凝土浇筑施工中，钢筋笼采用现有补救措施的抗浮效果不稳定的问题。
