Reinforcement cage lowering positioning device and positioning method
The invention provides a steel reinforcement cage lowering positioning device and method, and relates to the technical field of steel pile foundation construction. The pile casing is buried in the excavated pile hole; based on the pile hole design coordinate circle point, measuring the installation circle point of the pile casing so as to obtain the accurate installation position of the pile casing; the relative positions of the two positioning bearing frames on the top of the pile casing are adjusted through limiting mechanisms connected with the positioning bearing frames; then the corresponding positioning bearing frames are fixed to the top of the pile casing through the limiting mechanisms; the positioning support connecting beam and the reinforcement cage are sequentially assembled; lowering the reinforcement cage until the upper end of the reinforcement cage is lower than the top of the pile casing; then the positioning supporting frame is erected on the lug plate, then the positioning support can be in lap joint with the positioning supporting frame, and the positioning support is fixed to the upper position of the positioning supporting frame through the limiting piece; the installation precision of the reinforcement cage is ensured; and deviation of the reinforcement cage in the steel casing during pouring is avoided, the bearing capacity and stability of the pile foundation are improved, and the construction quality of the pile foundation is improved.
本发明提出了一种钢筋笼下放定位装置及定位方法，涉及钢桩基础施工技术领域。将护筒埋设于开挖完成的桩孔内；基于桩孔设计坐标圆点测量护筒的安装圆点，从而得出护筒的准确安装位置；通过与定位支承架连接的限位机构调整两个定位支承架在护筒顶部的位置相对位置；随后通过限位机构将对应的定位支承架固定在护筒的顶部；将定位支架连接梁以及钢筋笼依次组装；下放钢筋笼，直至钢筋笼的上端低于护筒的顶部；随后将定位支承架架设在耳板上，随后即可将定位支架搭接在定位支承架上，并利用限位件使定位支架固定在定位支承架上位；确保钢筋笼的安装精度；避免钢护筒内的钢筋笼在浇筑时偏位，提高桩基承载力和稳定性，增加桩基的施工质量。
